Embodiments for Carrying Out the Invention

[0016] The digital emergency electric safety control system of the present invention, that is, the DESCON emergency system, includes a power device, an instantaneous current value detection device, an instantaneous current value determination device, a first alarm notification information output means, a power supply automatic cut-off possible determination means, a first power supply cut-off device, a second power supply cut-off device, a housing temperature information acquisition means, a circuit temperature information acquisition means, a housing temperature monitoring means, a circuit temperature information monitoring means, a second alarm notification information output means, and a third alarm notification information output means. Hereinafter, in this specification and the drawings, the "digital emergency electric safety control system" may be referred to as the "DESCON emergency system" or "DESCON". The power device is one in which a power supply side circuit, which is an electric circuit from the power supply side, and a load side circuit, which is a plurality of electric circuits branched from the power supply side circuit and each leading to a plurality of loads, are electrically connected inside a housing. A first electrical device is interposed in the power supply side circuit inside the housing, and a second electrical device is interposed in each of the plurality of load side circuits inside the housing. The first electrical device interposed in the power supply side circuit and the plurality of second electrical devices interposed in each of the plurality of load side circuits are all arranged inside the housing.

[0017] Such power devices are, for example, various power transformation and distribution facilities, distribution boards, sub-distribution boards, lighting fixtures, power panels, control panels, remote control device panels, extension cords or wiring branch connection junction boxes between devices and instruments such as distribution boards and sub-distribution boards. The first electrical device is arranged inside the housing that constitutes the above-described power device, and is for making an electrical connection between the power supply side circuit from the power supply side and the load side circuit leading to the load. Examples include a main breaker and a leakage breaker. The plurality of second electrical devices are circuit breakers of a type different from the above-described main breaker, leakage breaker, etc. Examples include a magnetic switch, a power relay, and a solid state relay. Examples of the load that the load side circuit leads to include power, electrical, and electronic devices and equipment that receive power supply and operate, such as prime movers, elevators, air conditioning equipment, ventilation equipment, lighting equipment, refrigerated and frozen cases, refrigerators and freezers, measuring instruments, computer equipment, surveillance cameras, medical equipment, communication devices, etc., which are arranged and used inside and outside buildings, etc., and power, electrical, and communication devices and equipment that are arranged and used in vehicles and means of transportation such as trains, cars, airplanes, and ships, etc., and outlets to which these are connected. These loads will be connected to the tip sides of each of the plurality of load side circuits. The instantaneous current value detection device is connected to the above-described circuit and detects an instantaneous AC current value or an instantaneous DC current value, which is the instantaneous current value flowing through the circuit, at an instantaneous time. For example, it is connected to the above-described load-side circuit and detects an instantaneous AC current value or an instantaneous DC current value, which is the instantaneous current value flowing through the load-side circuit, at an instantaneous time.

[0018] As the instantaneous current value detection device, a current sensor using an instrument transformer called a CT (Current Transformer) or a DC instantaneous current measuring device using a Hall element illustrated in FIG. 17 can be adopted.

[0019] The instantaneous time unit in the detection at an instantaneous time is, for example, 1 / 12000 second = 83 microseconds, and can be arbitrarily set between 1 / 50,000 second (= 20 μsec) and 1 / 100,000 second (= 10 μsec). Also, within this range, it can be set to microseconds proportional to the performance level of the computer (PC) constituting the DESCON emergency system.

[0020] Setting the instantaneous time unit in the detection at an instantaneous time to microseconds between 1 / 50,000 second (= 20 μsec) and 1 / 100,000 second (= 10 μsec) is advantageous for detecting the risk of the tracking phenomenon earlier and taking necessary measures such as power-off before the tracking phenomenon occurs.

[0021] The instantaneous current value determination device performs a process of comparing the detected instantaneous current value with a preset allowable current value range.

[0022] For example, an instantaneous current value corresponding to 12 to 17 times the normal current value in the circuit where the instantaneous current value is detected is determined to be within the alarm issuance range described later.

[0023] Also, for example, an instantaneous current value in a range that exceeds 17 times and reaches up to 22 times the normal current value in the detected circuit is determined to be within the power supply cutoff range and within the warning range as described later.

[0024] When the instantaneous current value determination device determines that the instantaneous current value is within a predetermined warning range, the first warning notification information output means performs a process of outputting warning notification information together with information identifying the power device related to the housing to the administrator terminal used by the administrator who manages the power device and the operator terminal owned by the person in charge of managing the power device.

[0025] The administrator terminal can be configured by a personal computer or the like equipped with image information display means such as a monitor. The operator terminal can be configured by a mobile terminal such as a smartphone in which an application for operating the system of the present invention is downloaded. The administrator terminal and the operator terminal are connected to be capable of mutually exchanging information with a computer system including a server computer or the like that constitutes the digital emergency electric safety control system of the present invention, that is, the DESCON emergency system, via a communication network such as the Internet or a dedicated line.

[0026] When the instantaneous current value determination device determines that the instantaneous current value is within a predetermined power supply cutoff range, the power supply automatic cutoff possible determination means performs a process of determining whether the load to which the current of the determined instantaneous current value is supplied is a load capable of automatic power supply cutoff.

[0027] The first power supply cutoff device performs a process of automatically cutting off the power supply to the load determined to be capable of automatic power supply cutoff by the power supply automatic cutoff possible determination means.

[0028] When the second power supply cut-off device is determined to be unable to automatically cut off the power supply by the power supply automatic cut-off determination means, it cuts off the power supply to the load device control device that controls the load determined to be unable to automatically cut off the power supply, and then continues to perform a process of automatically cutting off the power supply to the load.

[0029] The inside-casing temperature information acquisition means constantly detects the temperature inside the casing described above, and performs a process of outputting, as digital information, the inside-casing temperature information, which is information regarding the detected temperature inside the casing, together with the information identifying the power device related to the casing. The circuit temperature information acquisition means, which consists of a digital temperature sensor, a digital thermometer, etc., constantly detects the temperature of the circuit described above, and performs a process of outputting, as digital information, the circuit temperature information, which is information regarding the detected temperature of the circuit, together with the information identifying the circuit where the temperature is detected. The inside-casing temperature monitoring means performs a process of comparing the temperature inside the casing acquired by the inside-casing temperature information acquisition means with a preset inside-casing monitoring temperature. The circuit temperature monitoring means performs a process of comparing the temperature of the circuit acquired by the circuit temperature information acquisition means with a preset circuit monitoring temperature. When the inside-casing temperature monitoring means determines that the temperature inside the casing acquired by the inside-casing temperature information acquisition means exceeds the inside-casing monitoring temperature, the second alarm notification information output means performs a process of outputting alarm notification information to the administrator terminal and the person-in-charge terminal together with the information identifying the power device related to the casing. When the load-side circuit temperature monitoring means determines that the temperature of the circuit acquired by the circuit temperature information acquisition means exceeds the circuit monitoring temperature, the third alarm notification information output means performs a process of outputting alarm notification information to the administrator terminal and the person-in-charge terminal together with the information identifying the determined circuit.

[0030] The digital emergency electric safety control system of the present invention, i.e., the DESCON emergency system, is composed of a computer system including a server computer and the like. Although not shown, this computer system includes a CPU that controls to realize various functions of the system of this embodiment according to an operating system, a predetermined computer program installed or downloaded, etc., a storage unit that stores the operating system, various computer programs, etc., and stores data necessary for the CPU to execute processing for each control, a ROM as the storage unit, a RAM, a hard disk, an information input / output unit such as a communication interface that stores data necessary for the CPU to execute processing and is also used as a work area where information is appropriately rewritten by the CPU, and these are configured to be connected by necessary bus lines and are composed of a computer.

[0031] The processing operations performed by the above-described instantaneous current value determination device, first warning notification information output means, power supply automatic cutoff possible determination means, first power supply cutoff device, second power supply cutoff device, housing temperature monitoring means, circuit temperature information monitoring means, second warning notification information output means, third warning notification information output means, etc. are executed by such a computer system.

[0032] The above-described instantaneous current value determination device, first warning notification information output means, power supply automatic cutoff possible determination means, first power supply cutoff device, second power supply cutoff device, housing temperature monitoring means, circuit temperature information monitoring means, second warning notification information output means, third warning notification information output means, etc. do not necessarily have to be configured such that all of these are provided in one device or equipment. For example, a device or equipment having some of these configurations may be provided in a power device, and this may be provided at a location separate from the power device and be connected to another device or equipment composed of a computer having other configurations so as to be able to communicate information via a wired or wireless network. Alternatively, a device or equipment having some of the configurations described above in the power device may be deployed, which is deployed at a location separate from the power device and is connected via a wired or wireless network so as to be capable of information communication with other devices or equipment composed of a computer having some of the other configurations and other devices or equipment composed of a computer having the remaining part of the other configurations. In the above, a server computer installed on the cloud may be included in one or more other devices or equipment that are deployed at a location separate from the power device, are connected via a wired or wireless network, and have some or the remaining configurations of the other configurations described above.

[0033] <An example of a tracking detection system in the DESCON emergency system> The above-described DESCON emergency system can be configured to include a tracking detection system described below. In this tracking detection system, as shown in FIG. 16, 1) the analog instantaneous AC current value detected by the current detection CT is converted into an analog voltage value, 2) the analog voltage value is converted into a digital voltage value, and 3) the digital voltage value is converted into a current value to detect abnormal currents such as sparks and tracking.

[0034] This series of processing operations can be configured to be realized by, for example, a microcontroller or a microprocessor in the form of a printed circuit board.

[0035] In this tracking detection system, for example, a current of 50 Hz can be measured for 1 / 20,000 seconds and a current of 60 Hz can be measured for 1 / 16,666 seconds to measure short-circuit currents such as sparks and tracking phenomena that occur instantaneously and detect large currents of sparks and tracking.

[0036] 50 Hz detects the instantaneous current in units of 1 / 20,000 seconds, and 60 Hz detects the instantaneous current in units of 1 / 16,666 seconds, converts the detected analog current value into an analog voltage value, converts the converted analog voltage value into a digital voltage value, and further converts it into a current value to detect abnormal currents such as sparks and tracking.

[0037] Such a tracking detection system can be called a DESCON tracking detection digital system. The above-mentioned DESCON tracking detection digital system is a tracking detection system in an electric circuit where an alternating current is flowing.

[0038] <Another example of the tracking detection system in the DESCON emergency system> The above-mentioned DESCON emergency system can be configured to include other tracking detection systems described below. In this tracking detection system, as shown in FIG. 17, 1) convert the analog instantaneous DC current value detected by a DC instantaneous current meter into an analog voltage value, 2) convert the analog voltage value into a digital voltage value, and 3) convert the digital voltage value into a current value to detect abnormal currents such as sparks and tracking.

[0039] As the DC instantaneous current meter, as exemplified in FIG. 17, a Hall element detector, a fluxgate detector, or other DC instantaneous current meters known in this technical field can be adopted.

[0040] The process of converting the analog voltage value into a digital voltage value can be configured to be realized by, for example, a microcontroller or a microprocessor in the form of a printed circuit board.

[0041] In this tracking detection system, for example, the current can be measured at 1 / 10,000 seconds to 1 / 100,000 seconds to 1 / n seconds, and the short-circuit current such as sparks and tracking phenomena that occur instantaneously can be measured to detect the large current of sparks and tracking.

[0042] Detect the instantaneous current in units of 1 / 10,000 second to 1 / 100,000 second to 1 / n second, convert the detected analog current value to an analog voltage value, convert the converted analog voltage value to a digital voltage value, and further convert it to a current value to detect abnormal currents such as sparks and tracking.

[0043] For example, it is a tracking detection system for DC electrical equipment such as railways and DC motors of electric vehicles, and DC power supply devices such as solar power generation and storage batteries.

[0044] Such a tracking detection system can be called a DESCON tracking detection digital system. The above-mentioned DESCON tracking detection digital system is a tracking detection system in an electric circuit where a direct current is flowing.

[0045] <An example of the tracking detection function in the DESCON emergency system> The DESCON emergency system can be configured to have a tracking detection function, which is illustrated by an example in FIG. 20. The tracking detection function can be exerted by the tracking detection system in the above-mentioned DESCON emergency system.

[0046] In this tracking detection function, an instantaneous current value detector: CT (Current Transformer) is installed in the corresponding circuit such as a switchboard, distribution board, control panel, and terminal equipment, and the CT detects the analog current value detected in an instantaneous time. The instantaneous time unit in analog current detection is, for example, 1 second / 12,000 (83 μsec) to 1 second / 50,000 (20 μsec). Also, for example, it can be 1 second / 100,000 (10 μsec) to 1 second / N value in proportion to the performance of the PC.

[0047] Next, convert the analog current value to an analog voltage value. For example, convert the analog current value detected at the instantaneous time such as the above 1 second / 12,000 (83 μsec) to 1 second / 50,000 (20 μsec) to 1 second / 100,000 (10 μsec) to 1 second / N value (N μsec) to an analog voltage value.

[0048] Next, convert the analog voltage value to a digital voltage value. That is, perform A / D conversion on the converted analog voltage value to a digital voltage. Next, convert the digital voltage value converted as described above to a current value. Next, based on the current value converted as described above, detect and judge abnormal current. For example, detect and judge an instantaneous current value with a magnification that protrudes to 30 to 100 times the allowable current value as an abnormal current such as a short circuit, spark, or tracking phenomenon in the corresponding circuit.

[0049] The above-described processing operations can be configured to be realized by, for example, a microcontroller or a microprocessor in the form of a printed circuit board. Also, these processes can be executed by the CPU of a computer.

[0050] When an abnormal current is detected by the above-described processing, if automatic shutdown is possible, automatically shut off the power supply to the circuit of the corresponding distribution board.

[0051] Also, send an alert to the PCs, tablets, smartphones, etc. of the relevant personnel. This alert email can be sent multiple times until the relevant personnel confirm and reset it, so that it is possible to handle the recovery safely after automatic shutdown.

[0052] Also, the board and equipment of the corresponding circuit can be confirmed and handled remotely or on-site.

[0053] In this way, the tracking detection function, an example of which is described in Fig. 20, that the DESCON emergency system is equipped with can continuously transmit alerts regarding alert transmission and automatic shutdown until the relevant personnel confirm and reset the alerts sent, so that electrical burnout and electrical fires can be perfectly controlled and prevented.

[0054] <An example of the joule heat detection function in the DESCON emergency system> The DESCON emergency system can be configured to have a joule heat detection function, an example of which is described in Fig. 21. In this joule heat detection function, the temperature of the connection terminal block for each circuit where a circuit breaker is installed is monitored. That is, the temperature sensor monitors the temperature rise due to the joule heat of the connection terminal block.

[0055] Assume that the circuits where circuit breakers are installed, for example, the cables, are cables with different temperature ratings such as 60 degrees for IV·KIV, 60 degrees for VVF, 60 degrees for VCT, 75 degrees for HIV, 90 degrees for CV, and 90 degrees for MLFC. In this case, based on the allowable temperature of the wires and the like, the attention temperature of the cables, wires, etc. is determined arbitrarily in advance as judgment information for the allowable temperature. For example, +10 to 15 degrees, etc. are stored in the database, and when the corresponding panel, cable, circuit, etc. reach the attention temperature, an alert can be sent to the relevant personnel's PC, tablet, and smartphone in the form of sound, numerical values, and images.

[0056] For example, a temperature sensor detects temperature anomalies caused by temperature rises due to loosening, gaps, disengagement, etc. of connection terminal blocks.

[0057] When it can be determined that there is a temperature anomaly and automatic shutdown is possible, the power supply of the circuit of the corresponding distribution board is automatically shut off.

[0058] If the temperature rises to a predetermined level, the power supply to the circuit of the corresponding switchboard will be automatically cut off. For example, it can detect and judge the occurrence of the spark tracking phenomenon due to the melting and burning of the coating materials of the electrical resistance of the corresponding cable, wire, circuit, etc., and can prevent electrical burnout and electrical fire accidents.

[0059] In this case, it can be in a form that sends alerts to the PCs, tablets, smartphones, etc. of the relevant personnel. The alert incoming sound will ring until the relevant personnel confirm and reset it, or emails can be sent continuously multiple times and the incoming sound will continue to prevent the relevant personnel from missing the confirmation.

[0060] Also, the switchboard and equipment of the corresponding circuit can be checked and dealt with remotely or on-site.

[0061] In this way, the Joule heat detection function of the DESCON emergency system, an example of which is illustrated in Fig. 21, can continuously send the alerts transmitted to the relevant personnel until they confirm and reset the alerts, so that electrical burnout and electrical fires can be perfectly controlled and prevented regarding the above-mentioned alert transmission and automatic shutdown.

[0062] <An example of the overcurrent detection function in the DESCON emergency system> The DESCON emergency system can be configured to have an overcurrent detection function, an example of which is illustrated in Fig. 22. In this overcurrent detection function, the current values of each circuit where circuit breakers are installed are monitored.

[0063] For example, an instantaneous current value detector CT (Current Transformer) is used to monitor the overcurrent of each circuit.

[0064] The operating time of the circuit breaker for different current values is, for example, when the rated current value is 30A, at 1.25 times the rated current value, i.e., 37.5A, the operating time of the protective shutdown of the corresponding circuit breaker is 60 minutes or less.

[0065] For example, when a wiring breaker such as a breaker for protecting a circuit is not properly installed, an overcurrent occurs in the circuit and the current increases. As a result, the wire generates significantly more heat due to Joule heat. If this state continues, the temperature of the wire rises to a high level, and the insulating material of the wire melts.

[0066] For example, based on the allowable temperatures of cables, wires, etc. for different temperatures such as the allowable temperature of IV·KIV being 60 degrees, VVF being 60 degrees, VCT being 60 degrees, HIV being 75 degrees, CV being 90 degrees, MLFC being 90 degrees, etc., arbitrarily determined in advance, for example, with respect to the allowable temperature, for example, for distribution boards, sub - distribution boards, junction boxes, connection devices, terminal devices, connected equipment, electrical equipment and appliances, the above - mentioned cables, wires, etc., the caution temperature can be used as judgment information. For example, +10 to 15 degrees can be stored in a database, and when the corresponding board, cable, circuit, etc. reaches the caution temperature, voice, numerical values, and images are sent as alerts to the PCs, tablets, and smartphones of relevant personnel.

[0067] An instantaneous current value detector CT (Current Transformer) is installed for each of the above - mentioned circuits to detect abnormal current values, and the temperature rise of cables, wires, connection fittings, etc. is detected by a temperature sensor.

[0068] When an abnormal current or temperature is detected and automatic shutdown is possible, the power supply of the circuit of the corresponding sub - distribution board is automatically shut off.

[0069] If the temperature rises to a predetermined temperature, the power supply of the circuit of the corresponding sub - distribution board is automatically shut off. For example, when the coating material of the electrical resistance of the corresponding cable, wire, circuit, etc. melts or burns out, the occurrence of a spark - tracking phenomenon is detected and judged, and it is possible to prevent electrical burnout and electrical fire accidents.

[0070] In this case, an alert is sent to the PCs, tablets, smartphones, etc. of relevant personnel. The alert incoming sound can be made to ring until the relevant personnel confirm and reset it, or emails can be sent continuously multiple times and the incoming sound can be continuous to prevent the relevant personnel from missing the confirmation.

[0071] The panel and equipment of the corresponding circuit can be checked and handled remotely or on-site.

[0072] In this way, the overcurrent detection function of the DESCON emergency system, as illustrated in Fig. 22, can continuously send alerts regarding the above-mentioned alert transmission and automatic shutdown until the relevant personnel confirm and reset the sent alerts, thus fully controlling and preventing electrical burnout and electrical fires.

[0073] <An example of the leakage current detection function in the DESCON emergency system> The DESCON emergency system can be configured to have a leakage current detection function, as illustrated by an example in Fig. 23. In this leakage current detection function, the leakage overcurrent of each circuit equipped with a circuit breaker is monitored by a leakage current value detector ZCT (Zero-phase Current Transformer).

[0074] When ZCT detects an abnormality in the leakage overcurrent of a circuit, for example, when a predetermined leakage current value is reached and automatic shutdown is possible, the power supply to the circuit of the corresponding distribution board is automatically shut off. For example, it can detect and judge insulation defects such as aging of the corresponding cable, wire, and circuit, and prevent electrical burnout, electrical fire accidents, and electric shock accidents.

[0075] When the leakage current value detected by ZCT reaches the attention current value, it can be configured to send alerts in the form of sound, numerical values, and images to the PCs, tablets, and smartphones of the relevant personnel. The alert incoming sound can be configured to ring until the relevant personnel confirm and reset it, or emails can be sent continuously multiple times and the incoming sound can be continuous to prevent the relevant personnel from missing the confirmation.

[0076] The panel and equipment of the corresponding circuit can be checked and handled remotely or on-site.

[0077] In this way, the leakage current detection function, an example of which is illustrated in Fig. 23, provided by the DESCON emergency system can continuously transmit alerts related to the above-mentioned alert transmission and automatic shutdown until the relevant personnel confirm and reset the sent alerts, so as to perfectly control and prevent electrical burnout and electrical fires.

[0078] <An example of the breaker system in the DESCON emergency system> The above-mentioned DESCON emergency system can be configured to include the breaker system described below. As shown in Fig. 19 as an example, this breaker system incorporates and houses the above-mentioned tracking detection function, joule heat detection function, overcurrent detection function, leakage current detection function, and automatic shutdown function in the wiring breaker (circuit breaker) in the DESCON emergency system to prevent electrical fires and burnout accidents.

[0079] Any of the CT (Current Transformer) in the above-mentioned tracking detection function and overcurrent detection function, the temperature sensor in the above-mentioned joule heat detection function, and the leakage current value detector ZCT (Zero-phase Current Transformer) in the above-mentioned leakage current detection function are built into the circuit breaker.

[0080] As a result, this breaker system can detect abnormalities in tracking, joule heat, overcurrent, leakage current, etc. for each circuit of, for example, distribution boards, sub-distribution boards, control panels, electrical equipment, load devices, etc., in units of main breakers (wiring breakers). When abnormal values of pre-determined tracking current, temperature, overcurrent, and leakage current are detected, alerts will be sent to the PCs, tablets, smartphones, etc. of the relevant personnel in the form of sound and images.

[0081] In addition, when a predetermined alarm current, alarm temperature, and alarm leakage current are detected, an alert can be sent to the PCs, tablets, smartphones, etc. of relevant personnel via voice and images, and the corresponding circuit or main breaker can be set to an automatic cut-off mode.

[0082] Such a breaker system can be called a DESCON smart breaker system, as exemplified in FIG. 19.

[0083] <Various embodiments of the DESCON emergency system of the present invention and various functions exhibited> The configuration of the DESCON emergency system detects current, voltage, temperature, images, etc. of power receiving and transforming equipment, switchboards, distribution boards, control panels, main lines, circuits, breakers, remote devices, etc. and load terminal equipment, electrical equipment, etc., and determines whether they are normal values or abnormal values by referring to various databases input in advance. For example, as attention signals at the attention stage of abnormality for each value in the abnormal value, relevant personnel are alerted with information such as voice, numerical values, and images about, for example, customer name, building name, facility name, location, relevant panel, type of lighting and power of the circuit, etc., capacity, electrical equipment at the system terminal, load equipment name, etc. Alerts are sent in real time via voice, images, and numerical values using a PC, tablet, or smartphone.

[0084] According to the DESCON emergency system, when the abnormal numerical value becomes high, an alert is sent "as a warning signal via voice, image, and numerical value", "the relevant equipment panel, main line, circuit, breaker, etc. are automatically cut off", "the relevant personnel are alerted that the automatic cut-off has occurred via voice, image, and numerical value", "continuous transmission is performed until the relevant personnel confirm and reset", and an embodiment can be achieved where "the restoration after the automatic cut-off can be safely handled in real time".

[0085] The above automatic cutoff is applicable to cases where various equipment such as products, manufacturing, etc. by computer programs like AI, IoT, etc., and lighting, elevators, etc. in logistics centers, large freezers, refrigerators, etc., commercial facilities where many people gather, terminal buildings, hotels, etc., data centers for important data research test results, etc., substations of infrastructure, etc., and corresponding various equipment such as trains, ships, etc. in transportation, electrical equipment, etc., and corresponding terminal equipment, electrical equipment, etc. are automatically cut off as described above. When these are controlled by a computer based on a computer program, when terminal equipment such as control is to be shut down by a predetermined program, 2) The DESCON emergency system composed of distribution boards, sub-distribution boards, control panels, main lines, circuits, breakers, etc. and remote devices for each system, cloud servers, LAN, etc. has a function that the remote devices of the corresponding distribution boards, sub-distribution boards, control panels, etc. transmit signals to the protection stop device through an emergency response protection program composed of remote devices for each system, cloud servers, LAN, etc., and the batch or selected terminal equipment such as control shuts down according to a predetermined program, and has a normal and safe stop function control means, and also has a control means for confirming the stop signal.

[0086] The DESCON emergency system can be implemented in such a way that whether the current, voltage, insulation, temperature, etc. of the above equipment, main lines, circuits, breakers, terminal load equipment, electrical equipment, etc. are normal or abnormal is calculated and judged by a program predetermined for, for example, customer name, building name, facility name, location, each panel circuit, etc. of electric lights and power, compared with numerical values such as annual, seasonal, monthly, weekly, daily, hourly, minute, etc. and annual, seasonal, monthly, weekly, daily, hourly, minute, etc., the numerical values such as the above current, voltage, insulation, temperature, etc. and normal and abnormal are recorded in a database, and the above content is periodically displayed on the PC, tablet, smartphone, etc. of the relevant person and the display by a program, or automatically printed.

[0087] The DESCON emergency system is connected to the fire detectors on the disaster prevention panel of building facilities, such as fire prevention facilities. It receives abnormal signals from the smoke detectors and heat detectors of the fire alarm, identifies the received floor number and area, and cuts off the electricity and equipment necessary for evacuation, fire notification, broadcasting equipment, emergency lights, lighting, mechanical smoke exhaust, air supply, etc. outside the building and the previously defined lighting and power equipment automatically. It alerts relevant personnel in real-time with voice, images, and numerical values on a PC, tablet, or smartphone. For example, it transmits the customer name, building name, facility name, location, relevant panel, circuit, etc., the type and capacity of lighting and power, and continuously transmits until the relevant personnel confirm and reset it. It can be implemented in a form that can respond safely in real-time to the restoration after automatic shutdown.

[0088] The DESCON emergency system, for example, in the connection fittings of distribution boards, sub-distribution boards, control panels, terminal equipment, electrical machinery equipment, etc. in the power transmission and transformation equipment system, if dust, garbage, etc. adhere after a long time, or there is humidity or the relevant connection fitting circuit and terminal fittings loosen in proportion to the elapsed time, and there is a possibility of a tracking phenomenon occurring, it can arbitrarily define, for example, a caution temperature, an alarm temperature, etc. in advance, program and input them. If the alarm temperature is reached, it alerts relevant personnel's PCs, smartphones, tablets, etc. For example, it transmits the customer name, building name, facility name, location, relevant panel, circuit, etc., the type and capacity of lighting and power, and continuously transmits until the relevant personnel confirm and reset it. It transmits, automatically cuts off the corresponding cable, circuit, etc., alerts the relevant personnel that it has been automatically cut off, and continuously transmits until the relevant personnel confirm and reset it. It can be implemented in a form that can respond safely to the restoration after automatic shutdown.

[0089] The DESCON emergency system, for example, in the connection fittings of switchboards, distribution boards, control panels, terminal equipment, electrical machinery equipment, etc. in the power receiving and transforming equipment system, after a long time, dust, garbage, etc. adhere, and due to moisture, etc. or in proportion to the elapsed time, the corresponding connection fitting circuits, terminal fittings, etc. become loose, and due to the increase in the electrical and thermal resistance value in gaps, etc., Joule heat of electrical resistance heat exceeding the allowable temperature of each wire type is generated in the wiring, circuit, etc., and the temperature of each wire, etc. exceeds the allowable temperature of the corresponding type, and the electrical insulation coating material deforms and melts in proportion to the high temperature, causing the + and - of electricity to short-circuit and spark, and there is a risk of electrical fire accidents, etc. In advance, for example, arbitrarily set the caution temperature, alarm temperature, etc., program and input them. When the alarm temperature is reached, an alert is sent to the PCs, smartphones, tablets, etc. of the relevant personnel, for example, the customer name, building name, facility name, location, type, capacity of lighting and power in the corresponding panel, circuit, etc. are transmitted, and continuous transmission is carried out until the relevant personnel confirm and reset. After transmission, the corresponding cable, circuit, etc. are automatically cut off, and an alert is sent to the relevant personnel that the automatic cut-off has been made, and continuous transmission is carried out until the relevant personnel confirm and reset. It can be made into an embodiment capable of implementing recovery safety measures after automatic cut-off.

[0090] The DESCON emergency system, in proportion to the number of years elapsed of the connection fittings, terminals, cables, wiring, circuits, etc. of switchboards, distribution boards, control panels, terminal equipment, electrical machinery equipment, etc. in the power receiving and transforming equipment system, the connection fittings, etc. become loose, and due to the decrease in the conduction area in gaps, etc., electrical resistance heat is generated, and in proportion to the elapsed time, the temperature rises due to Joule heat and may reach or exceed the allowable temperature of each wire. In advance, for example, arbitrarily set the caution temperature, alarm temperature, program and input them. When the alarm temperature is reached, an alert is sent to the PCs, smartphones, tablets, etc. of the relevant personnel, for example, the customer name, building name, facility name, location, type, capacity of lighting and power in the corresponding panel, circuit, etc. are transmitted, and continuous transmission is carried out until the relevant personnel confirm and reset. After transmission, the corresponding cable, circuit, etc. are automatically cut off, and an alert is sent to the relevant personnel that the automatic cut-off has been made, and continuous transmission is carried out until the relevant personnel confirm and reset. It can be made into an embodiment capable of implementing recovery safety measures after automatic cut-off.

[0091] The DESCON emergency system can detect, within an extremely short period of time, a current that causes the insulation coating materials of wires, circuits, etc. to melt and burn out due to adhesion of dust, dirt, etc. to each panel, connection fittings, terminals, circuits, terminal devices, etc., moisture due to humidity, or an increase in the temperature of each panel, connection fittings, terminals, circuits, electric wires, etc., resulting in a short circuit or spark instantaneously. It can detect a short circuit or spark current value, which is, for example, 50 to 80 times the normal current magnification, in the tracking phenomenon of short circuits and sparks. This pre-determined 50 to 80 magnification, for example, a 50 to 80 magnification current value, is sent as a short circuit warning and spark warning signal to the PCs, smartphones, tablets, etc. of relevant personnel as an alert. For example, it transmits the customer name, building name, facility name, location, type, capacity of lighting and power for the corresponding panel, circuit, etc., automatically shuts off the corresponding panel, circuit, etc., and alerts the relevant personnel that the automatic shut-off has occurred. It sends the alert multiple times until the relevant personnel confirm and reset it, and can be implemented in a form that can handle the recovery safety measures after the automatic shut-off.

[0092] The detection within an extremely short period of time can be, for example, an instantaneous detection at 1 / 12000 seconds = 83 microseconds. Here, 12000 is, for example, a common multiple of 50HZ and 60HZ.

[0093] The DESCON emergency system is designed to protect electrical equipment from overcurrents exceeding the rated current. It monitors the overcurrents in the receiving and transforming equipment, switchboards, distribution boards, control panels, terminal equipment, electrical machinery, etc., as well as the current (A) in the main lines, circuits, etc. For example, the rated current is divided into ranges such as 30A or less, 30A to 50A or less, ···, 445A to 400A or less, 800A to 1000A or less, 1600A to 2000A or less, etc. The allowable current is 1.25 times the rated current, and the operating time of the allowable current breaker is 60 minutes or less. When the allowable current is 2.0 times the rated current, the operating time of the allowable current breaker is 6 minutes or less to 120 minutes or less. Due to the relationship of electrical equipment safety protection, if each current exceeds the rated current, the breaker will operate after a certain time. However, for example, the required current of a specific single unit, connection, etc. of the corresponding terminal load equipment, electrical machinery, etc. is not the current value set above until the breaker operates. Instead, it may be a weak overcurrent that requires a long time or the insulation and coating materials are consumed due to aging, etc. When the equipment operates for 24 hours a year, depending on the overload current situation, etc., according to the overcurrent situation of the equipment, for example, the maximum allowable temperature of the high-voltage transformer of the receiving and transforming equipment, and the load factor and operating factor of the low-voltage lighting and power equipment capacity relative to the lighting and power equipment capacity of the same equipment reach the allowable factor. Before that, arbitrary attention temperature and attention current are determined in advance, and alerts are sent to the PCs, smartphones, tablets, etc. of relevant personnel. For example, the customer name, building name, facility name, location, type, capacity, etc. of lighting and power in the corresponding panel, circuit, etc. are transmitted. The alerts are sent repeatedly until the relevant personnel confirm and reset. Before the load factor and operating factor of the low-voltage lighting and power equipment capacity relative to the lighting and power equipment capacity of the same equipment exceed the allowable factor, the corresponding low-voltage lighting, power distribution board, lighting, power distribution board, control panel, terminal load equipment, electrical machinery, etc. are automatically shut off in a determined priority order without the need for automatic shutdown. By doing so, the system reduces the maximum allowable temperature of the transformer of the receiving and transforming equipment and the load factor and overcurrent factor of the allowable current. It can be automatically shut off, and alerts are sent to relevant personnel to inform them of the automatic shutdown. The alerts are continuously sent until the relevant personnel confirm and reset. It is also possible to implement a recovery safety response after automatic shutdown.

[0094] <Flowchart related to an embodiment of the tracking detection function in the DESCON emergency system> Install an AC instantaneous current value detector in the corresponding circuits of distribution boards, sub-distribution boards, control panels, terminal equipment, etc., and detect the analog current value detected at an instantaneous time. Detect the instantaneous current value of the corresponding circuits of distribution boards, sub-distribution boards, control panels, terminal equipment, etc. As the AC instantaneous current value detector, a current sensor using an instrument current transformer called CT (Current Transformer) can be adopted. In this specification and drawings, the AC instantaneous current value detector may be simply displayed as "CT".

[0095] As described above, the detection at an instantaneous time can be, for example, the detection at 1 / 12000 seconds obtained by dividing by 50×60×4 = 12000, which is the least common multiple of 50HZ and 60HZ.

[0096] As described above, the instantaneous time unit in the detection at an instantaneous time is, for example, 1 / 12000 seconds = 83 microseconds, and it can be arbitrarily set between 1 / 50,000 seconds (= 20μsec) and 1 / 100,000 seconds (= 10μsec). Also, within this range, it can be set to microseconds proportional to the performance of the computer (PC) constituting the DESCON emergency system.

[0097] Setting the instantaneous time unit in the detection at an instantaneous time to microseconds between 1 / 50,000 seconds (= 20μsec) and 1 / 100,000 seconds (= 10μsec) is advantageous for detecting the risk of the tracking phenomenon earlier and taking necessary measures such as power-off before the tracking phenomenon occurs.

[0098] Subsequently, compare the instantaneous current value detected as described above with a preset allowable current value, and determine the short circuit, spark, tracking phenomenon, etc. of the corresponding circuit.

[0099] For example, an instantaneous current value with a magnification factor that exceeds 30 times the allowable current value, which is the current value allowed in the corresponding circuit such as a distribution board, sub-distribution board, control panel, terminal equipment, etc., is determined as an abnormal current leading to short circuits, sparks, tracking phenomena, etc. in the corresponding circuit.

[0100] The current value determined as an abnormal current value can be arbitrarily set within the range of 30 times to 100 times the allowable current value, which is the current value allowed in the corresponding circuit such as a distribution board, sub-distribution board, control panel, terminal equipment, etc.

[0101] Note that as described above, after detecting the instantaneous current value as an analog current value, a process of converting the analog current value into an analog voltage value can be performed.

[0102] For example, convert the analog current value detected at an instantaneous time such as the above-mentioned 1 / 50,000 seconds (=20 μsec) to 1 / 100,000 seconds (=10 μsec), for example, 1 / 12,000 seconds (83 μsec) into an analog voltage value.

[0103] In this case, subsequently, convert the analog voltage to a digital voltage (A / D conversion), and then convert the digital voltage into a digital current value. For example, through a computer program, the digital voltage value after A / D conversion as described above is converted into a digital current value by the processing operation performed by the CPU of the computer.

[0104] The digital current value thus converted is treated as the detected instantaneous current value, and this is compared with the preset allowable current value as described above, and it is also possible to adopt an embodiment in which a determination is made on short circuits, sparks, tracking phenomena, etc. in the corresponding circuit.

[0105] When it can be determined that the detected instantaneous current value is an abnormal current leading to the occurrence of short circuits, sparks, tracking phenomena, etc. in the corresponding circuit compared with the preset allowable current value, it is determined whether it is possible to automatically cut off the corresponding circuit of the distribution board, sub-distribution board, control panel, terminal equipment, etc.

[0106] When it can be determined that automatic shutdown is possible, the power supply of the corresponding circuit is automatically shut down.

[0107] On the other hand, if the corresponding circuit determined to have an abnormal current is controlled by a computer or the like and it is necessary to cut off the power after first cutting off the computer or the like that is performing the control, first, the power supply to the computer or the like that is performing the control is cut off, and subsequently, the power supply can be cut off.

[0108] Send alerts to the PCs, tablets, smartphones, etc. of relevant personnel. The alert emails are sent repeatedly until the relevant personnel confirm and reset them, and it is a system that can handle recovery safety after automatic shutdown. Check and respond to the panel and equipment of the corresponding circuit remotely or on-site.

[0109] <DESCON Emergency System Joule Heat Detection Function Flow> Monitor the temperature of wires, connection fittings, etc. for each circuit Monitor the temperature rise due to the Joule heat of cables, wires, etc. with a temperature sensor.

[0110] For example, based on the allowable temperatures of cables, wires, etc. for different temperatures such as the allowable temperature of IV·KIV being 60 degrees, VVF being 60 degrees, VCT being 60 degrees, HIV being 75 degrees, CV being 90 degrees, MLFC being 90 degrees, etc., for example, with respect to the arbitrarily determined allowable temperature in advance, for example, for the warning temperatures of distribution boards, sub-distribution boards, junction boxes, connection devices, terminal appliances, connected equipment, electrical appliances, the aforementioned cables, wires, etc., with a determination means, for example, +10 to 15 degrees are stored in the database in advance, and when the corresponding boards, cables, circuits, etc. reach the warning temperature, audio, numerical values, and images are sent as alerts to the PCs, tablets, and smartphones of relevant personnel.

[0111] Detect temperature abnormalities: Detect the temperature rise due to loosening, gaps, disengagement, etc. of connection terminal blocks, etc. with a temperature sensor.

[0112] If automatic shutdown is possible, automatically shut off the power supply of the circuit of the corresponding distribution board.

[0113] If the temperature rises to a predetermined temperature, automatically shut off the power supply of the circuit of the corresponding distribution board. For example, it is characterized by means for detecting and judging the occurrence of a spark tracking phenomenon due to the melting and burning of the coating material of the electrical resistance of the corresponding cable, wire, circuit, etc., and it is possible to prevent electrical burnout and electrical fire accidents.

[0114] Send an alert to the PCs, tablets, smartphones, etc. of the relevant personnel.

[0115] The alert incoming call sound rings until the relevant personnel confirm and reset it, or emails are sent continuously multiple times and the incoming call sound continues to prevent the relevant personnel from overlooking the confirmation. It is a system. Check and respond to the corresponding circuit board and equipment of the relevant circuit remotely or on-site.

[0116] <An example of the overcurrent detection function flow of the DESCON emergency system> Monitor overcurrent by circuit Install an alternating current instantaneous current value detector: CT on the corresponding circuits of distribution boards, sub-distribution boards, control panels, terminal equipment, etc., and monitor overcurrent by circuit.

[0117] The operating time of the breaker according to the current value is, for example, 1.25 times the rated current value of 37.5 A for a rated current value of 30 A, and the operating time of the protective interruption of the corresponding breaker is 60 minutes or less.

[0118] For example, when a wiring breaker such as a breaker for protecting a circuit is not properly installed, an overcurrent occurs in the circuit and the current increases, so the heat generation of the wire increases significantly due to Joule heat. If this state continues, the wire temperature rises to a high temperature and the insulating material of the wire melts.

[0119] For example, based on the allowable temperatures of cables, wires, etc. at different temperatures such as the allowable temperature of IV·KIV being 60 degrees, VVF being 60 degrees, VCT being 60 degrees, HIV being 75 degrees, CV being 90 degrees, MLFC being 90 degrees, etc., for a pre - arbitrarily determined allowable temperature, for example, for the allowable temperature, for example, in distribution boards, sub - distribution boards, junction boxes, connection devices, terminal appliances, connected equipment, electrical equipment and appliances, the cables, wires, etc., the caution temperature is determined by a judgment means. For example, +10 to 15 degrees is stored in a database, and when the corresponding boards, cables, circuits, etc. reach the caution temperature, audio, numerical values, and images are sent as alerts to the PCs, tablets, and smartphones of relevant personnel.

[0120] Detect current and temperature abnormalities An alternating - current instantaneous current - value detector CT is installed for each of the above - mentioned circuits to detect abnormal current values, and the temperature rise of cables, wires, connection fittings, etc. is detected by a temperature sensor.

[0121] When automatic shutdown is possible, the power supply of the circuit of the corresponding sub - distribution board is automatically shut off.

[0122] If the temperature rises to a predetermined temperature, the power supply of the circuit of the corresponding sub - distribution board is automatically shut off. For example, it is characterized by a means for detecting and judging the occurrence of a spark - tracking phenomenon due to the melting and burning of the coating material of the electrical resistance of the corresponding cables, wires, circuits, etc., and it is possible to prevent electrical burnout and electrical fire accidents.

[0123] Send alerts to the PCs, tablets, smartphones, etc. of relevant personnel. The alert incoming sound rings until the relevant person confirms and resets it, or emails are sent continuously multiple times and the incoming sound continues to prevent the relevant person from overlooking the confirmation. This is a system.

[0124] Check and respond to the corresponding circuit board and equipment remotely or on - site.

[0125] The joule heat - current detection device can be arbitrarily installed in 1 to n numbers on the power line.

[0126] The detection device can be configured to be connected to the power line but not to the network.

[0127] Each detection device can be directly connected to an upstream remote device in some way so that it can send signals to the remote device.

[0128] The above-mentioned Joule heat - current detection device can be directly connected to a remote device outside the control panel. In addition, it is also possible to configure the Joule heat - current detection devices (P4 - P5) installed arbitrarily in the number of 1 to n on the power line to be directly connected to the remote device 2 inside the control panel.

[0129] <One embodiment of the flow when cutting off at the time of temperature - current abnormality detection> The above-mentioned Joule heat - current detection device sends the value of the built - in sensor to the remote device. When the remote device detects an abnormality in temperature - current, it activates and cuts off the corresponding breaker.

[0130] The central control device constituting the DESCON emergency system sends a cutoff notice to the PCs, tablets, smartphones, etc. of relevant personnel through the cloud server.

[0131] <Another embodiment of the flow when cutting off at the time of temperature - current over - detection> The Joule heat - current detection device sends the value of the built - in sensor to the corresponding remote device. When the corresponding remote device detects a temperature - current over - condition, it activates and cuts off the corresponding breaker.

[0132] The central control device constituting the DESCON emergency system sends a cutoff notice to the PCs, tablets, smartphones, etc. of relevant personnel through the cloud server. <Deployment method of Joule heat - current detection device> In the information network (A) and control network (B) that make up the DESCON emergency system, the Internet (open public network) can be used at locations of the WAN (wide area network). When sending interruption notifications to the PCs, tablets, smartphones, etc. of relevant personnel, there are no particular problems with using the Internet.

[0133] However, except for sending interruption notifications, when making a connection between bases or performing remote access, it is conceivable to use a dedicated line or VPN (closed network) instead of the Internet, taking security into consideration. In that case, the location of the WAN can be replaced as needed. <Tracking Detection Function in the DESCON Emergency System> Conventional electrical protection breakers, etc., for example, the current measurement time is measured in units of time, minutes, and seconds with a current transformer (CT), etc. When the power frequency is 50 Hz, for example, it is usually measured at 0.1 sec (100 msec), and when it is 60 Hz, it is usually measured at 0.083 sec (83 msec). Thermal operating breakers and leakage breakers with safety protection functions for overcurrent, leakage, etc. of electrical equipment cut off the corresponding circuit, and they have a safety protection function. However, for tracking phenomena such as the short circuit and sparking of the corresponding part instantaneously, for example, in the case of conventional electrical equipment such as main lines, cables, and wiring, when the power frequency is 50 Hz, for example, usually 0.1 sec (100 msec), and when it is 60 Hz, usually 0.083 sec (83 msec), leakage breakers that operate by thermal operation based on such measurements do not sense phenomena such as instantaneous electrical burnout and ignition and do not perform protection operations, and the current situation of conventional protection breakers, etc. is that electrical burnout, electrical fire accidents, etc. occur.

[0134] In the DESCON emergency system, CTs are installed in the corresponding circuits of distribution boards, sub - distribution boards, control panels, terminal equipment, etc.

[0135] Convert the analog current value detected by CT at an instantaneous time of 1 / 50,000 seconds (=20 μsec) to 1 / 100,000 seconds (=10 μsec), for example, 1 / 12,000 seconds (83 μsec), etc. into an analog voltage value, and use a computer, PC, microcontroller, etc. to convert it into an instantaneous digital voltage of, for example, 1 / 50,000 seconds (=20 μsec) to 1 / 100,000 seconds (=10 μsec), for example, 1 / 12,000 seconds (83 μsec), etc., and convert and detect it into a digital current according to a program predetermined on a printed circuit board.

[0136] Convert the digital voltage value obtained by converting the digital voltage into a current into a digital current value as described above, and detect the current value of an abnormal phenomenon protruding instantaneously such as a short circuit or spark in the corresponding circuit at an instantaneous time of, for example, arbitrarily determined 1 / 50,000 seconds (=20 μsec) to 1 / 100,000 seconds (=10 μsec), for example, 1 / 12,000 seconds (83 μsec), etc.

[0137] Next, the power frequency can be, for example, 50 Hz, 60 Hz, or other frequencies, and convert the instantaneous analog current value CT current such as short circuit, spark, tracking phenomenon, etc. generated by the above equipment into a voltage. For example, install an analog-to-digital converter (A / DC) in the corresponding circuit, convert the detected analog current value into a digital voltage value, and convert the converted digital voltage value into an analog voltage value by converting the analog current value detected at an instantaneous time of, for example, arbitrarily determined 1 / 50,000 seconds (=20 μsec) to 1 / 100,000 seconds (=10 μsec), for example, 1 / 12,000 seconds (83 μsec), etc., and then convert this into a digital voltage, and judge the predetermined attention current magnification and alarm current magnification according to the magnification factor of the normal current. Then, send an alert of the attention current magnification and alarm current magnification to the PC, tablet, and smartphone of the relevant person.

[0138] The DESCON emergency system attaches the CT of the above-mentioned current detection device to the corresponding circuit to detect the current, and converts the current into voltage. For example, computers, PCs, microcontrollers, etc. and the functions of the printed circuit board convert the current into voltage. The current is converted into voltage, and an analog-digital converter is used to detect the instantaneous current of, for example, power frequencies of 50HZ and 60HZ at, for example, 1 / 12,000 seconds = 83μsec.

[0139] It detects the instantaneous current in units of 83μsec = 1 / 12,000 seconds, converts the detected analog current into an analog voltage value, performs A / D conversion on the converted analog voltage value into a digital voltage value, and converts it into a current value by the CPU to detect abnormal currents such as sparks and tracking.

[0140] The above-mentioned, for example, converts the current value detected by the CT into voltage in units of time, minutes, and seconds of 1 / 12,000 seconds (83μsec). From 0A where the alternating current power changes from a positive number to a negative number, for example, the initially detected negative current -1.4A, and the current -4.1A immediately before the magnification of 19.9 times of the current -81.7A which is 15 times or more of the arbitrarily predetermined normal current A. Using the current per 80μsec unit with the denominator -4.1A and the average negative current -2.0A of the above-mentioned negative current -1.4A to negative current -4.1A, for example, by 3 methods, etc., the normal magnification of each current A is calculated at 83μsec of 1 / 12000 detections per second.

[0141] Also, if the detected current detects 0A of the no-load current, it may be converted to 1.0 regardless of the positive and negative current relationship and used as the denominator.

[0142] The DESCON emergency system can input the above-mentioned positive and negative currents into the program as the prediction magnification of, for example, 15 times, arbitrarily determined in advance, for the spark and tracking phenomena, and as the spark and tracking phenomena at 20 times or more, and has a judgment means for sending alerts to the PCs, smartphones, tablets, etc. of the relevant personnel, and can perform control to automatically cut off the corresponding circuit at 25 times or more.

[0143] The DESCON emergency system can be configured to continuously transmit the above-mentioned alert multiple times until the relevant personnel confirm and reset the sent alert, so as to completely control and prevent electrical burnout and electrical fires.

[0144] According to the above, for example, currents with frequencies of 50Hz and 60Hz can be measured in 1 / 12,000 seconds of 83μsec, and short-circuit currents such as instantaneous sparks and tracking phenomena can be measured to detect large currents of sparks and tracking, thus forming a system.

[0145] The configuration of the DESCON emergency system is, for example, to install an AC instantaneous current value detector: CT in the corresponding circuits such as switchboards, distribution boards, control panels, and terminal equipment to detect the analog current value in an instantaneous time. The instantaneous time unit can be, as described above, for example, 1 / 50,000 seconds (=20μsec) to 1 / 100,000 seconds (=10μsec), or for example, 1 / 12,000 seconds (83μsec), etc.

[0146] The DESCON emergency system detects abnormal current values such as short sparks and tracking phenomena from the instantaneous current values in time units of seconds, minutes, and seconds, such as 1 / 50,000 seconds (=20μsec) to 1 / 100,000 seconds (=10μsec), or for example, 1 / 12,000 seconds (83μsec). For example, based on the verification data of lighting equipment, detected at the elapsed time unit of 1 / 12000 seconds (83μsec), the current magnification immediately before tracking after AC inversion = each current A / -1.4A, and the magnification of the average current from 4.15ms to 7.47msc after AC inversion = each current A / -2.0A. Current values such as the current magnification immediately before tracking = each current A / -4.1A are converted by the DESCON emergency system into the arbitrarily determined current value of 1 / 12,000 seconds = 83μsec to detect current values of short circuits, sparks, tracking phenomena, etc.

[0147] For example, current values such as the current magnification immediately before tracking after AC inversion detected in units of 83 μsec of elapsed time of lighting equipment = each current A / -1.4 A, the magnification of the average current from 4.15 ms to 7.47 ms after AC inversion = each current A / -2.0 A, and the current magnification immediately before tracking = each current A / -4.1 A, etc., which protrude to, for example, 30 to 100 times the allowable current value, are defined as short, spark, and tracking phenomena, and an arbitrarily determined value, for example, 10 to 50 times, of the magnification of the above current value is set as the attention current value and magnification, and an alert is sent to the relevant person's PC, smartphone, tablet, etc. and sent repeatedly until the relevant person confirms and resets it.

[0148] Taking, for example, 20 to 70 times, which is arbitrarily determined in advance for the above current value and magnification, as the alarm current value and magnification, automatically cut off the corresponding circuit of the corresponding low-voltage lighting, power distribution board, control panel, terminal load equipment, electrical equipment, etc., send an alert to the relevant person that the automatic cut-off has been made, and send it repeatedly until the relevant person confirms and resets it, and it is possible to take recovery safety measures after the automatic cut-off.

[0149] Regardless of the above, the normal current value may be the allowable current of each electric wire or, with the required current value of the terminal load equipment and electrical equipment connected to the corresponding board, etc. as the denominator, and the current value may be, in the same way as above, the magnification of the current value that protrudes instantaneously in the short, spark, and tracking phenomena, for example, 30 to 100 times. <An example of the configuration of the DESCON emergency system> Install an AC instantaneous current value detector (CT) in the corresponding circuit of the distribution board, switchboard, control panel, terminal equipment, etc., and detect the analog instantaneous current value in units of 83 μsec = 1 / 12,000 seconds.

[0150] Analog current-voltage conversion: Convert the detected analog current value into an analog voltage value.

[0151] A / D conversion: Convert the converted analog voltage value into a digital voltage by A / D conversion.

[0152] Converting digital voltage to current: The converted digital voltage value is converted to a current value by the CPU, and abnormal currents such as the tracking current of the corresponding circuit are detected in units of 83 μsec = 1 / 12,000 seconds.

[0153] The above current detection device (CT) is attached to the corresponding circuit to detect the current and convert the current to a voltage. For example, the function of a printed circuit board such as an IC is used to convert the current to a voltage. In a system for converting current to voltage, for example, it is possible to detect instantaneous currents that are common multiples of the power frequencies of 50 Hz and 60 Hz, for example, 12,000 times per second = 83 μsec.

[0154] For the above, for example, the current A detected in units of 83 μsec, starting from 0 A where the AC power changes from positive to negative, for example, the initially detected negative current -1.4 A, a current -81.7 A that is 19.9 times the arbitrary pre-determined normal current A, using the immediately previous current -4.1 A as the denominator, the current in each 80 μsec unit with the denominator -4.1 A, and the average negative current -2.0 A of the negative currents from -1.4 A to -4.1 A, for example, calculate the normal magnification of each current A in 83 μsec of 1 second / 12,000 detections by, for example, 3 methods.

[0155] In addition, if the normal no-load current of 0 A is detected, it may be converted to 1.0 regardless of the positive or negative current and used as the denominator.

[0156] The DESCON emergency system has a determination means that inputs the above positive and negative currents as the prediction magnification of the spark tracking phenomenon, which is arbitrarily determined in advance, for example, 15 times, and sends an alert to the relevant person's PC, smartphone, tablet, etc. when it is 20 times or more as the spark tracking phenomenon, and can be configured to perform control to automatically cut off the corresponding circuit when it is 25 times or more.

[0157] The DESCON emergency system can be configured to continuously send the above alerts many times until the relevant person confirms and resets the sent alert to fully control and prevent electrical burnout and electrical fires.

[0158] AC instantaneous current value detector: CT: Detects analog instantaneous current values in units of 83 μsec = 1 / 12,000 seconds.

[0159] Analog current-voltage conversion: Converts the detected analog current value into an analog voltage value.

[0160] A / D conversion: Converts the converted analog voltage value into a digital voltage by A / D conversion.

[0161] Conversion of digital voltage to current: The converted digital voltage value is converted into a current value by the CPU to detect abnormal currents such as the tracking current of the corresponding circuit. <An example of the system flow of the DESCON emergency system> An AC instantaneous current value detector (CT) is installed in the corresponding circuits of distribution boards, switchboards, control panels, terminal equipment, etc., and the current of the corresponding circuit is detected in units of 83 μsec = 1 / 12,000 seconds to detect abnormal current values of the spark tracking phenomenon.

[0162] The DESCON emergency system installs an AC instantaneous current value detector (CT) in the necessary boards, wirings, etc. in advance, such as the main power transformation equipment of electrical facilities, for example, the main trunk of low-voltage lighting and power equipment and distribution boards, branch trunks by system, distribution boards, control panels of control panels of terminal equipment, etc. Each current A is input into the remote device of the DESCON emergency system, and the analog data of the current meter CT is converted into voltage, for example, the digital voltage is converted into current of 83 μsec.

[0163] The central control device of the computer constituting the DESCON emergency system inputs the current of 83 μsec of the corresponding circuit into the database. If the magnification of the preset current A is reached, an alert is sent. If the preset current A is exceeded, the corresponding circuit is automatically cut off, and data is sent to the server device composed of the computer constituting the DESCON emergency system, and then sent to the headquarters, or the PCs, smartphones, and tablets of relevant personnel to prevent the spark tracking phenomenon in advance.

[0164] The DESCON emergency system continuously transmits alerts regarding alert sending and automatic shutdown multiple times until the relevant personnel confirm and reset the sent alerts, preventing electrical burnout and electrical fires with complete certainty.

[0165] <Configuration of Remote Devices Comprising the DESCON Emergency System> Built-in type remote device Install a CT in the corresponding circuit of a distribution board, switchboard, control panel, terminal equipment, etc., install a remote device (sometimes referred to as a "DESCON remote device") inside the corresponding board, and detect abnormal currents such as tracking currents in the corresponding circuit in units of 83 μsec = 1 / 12,000 seconds. Separate type (not built-in) remote device Install a CT in the corresponding circuit of a distribution board, switchboard, control panel, terminal equipment, etc., install the DESCON remote device near the corresponding board, and detect abnormal currents such as tracking currents in the corresponding circuit, for example, in units of 83 μsec = 1 / 12,000 seconds.

[0166] The remote device in the DESCON emergency system can be configured as the built-in type or the separate type according to the shape, situation, etc. of the corresponding board, etc.

[0167] The above-mentioned remote device in the DESCON emergency system detects abnormal short-circuit currents such as sparks and tracking, and realizes the above-mentioned functions.

[0168] The DESCON emergency system, for example, converts the instantaneous current value (analog instantaneous current value) detected by a mounted CT, which is the instantaneous current value leading to spark and tracking phenomena in, for example, secondary terminal appliance outlets such as low-voltage distribution boards, distribution boards, control panels, load terminal equipment, and electrical appliances, into an analog voltage, and then converts the analog voltage into a digital voltage measured at 1 second / 12,000, for example, 83 μsec, and the connected CPU measures the 83 μsec short-circuit and spark currents of the digital voltage as verification data.

[0169] Using the normal normal current A measured as described above as the denominator of a constant current, detect if the current at the instant of measurement of a pre-determined current, for example, 83 μsec, is 20 times, 25 times or more, automatically make a judgment, and send an alert to the relevant person's PC, smartphone, tablet, etc. with the content such as the corresponding building, floor, area, layout, etc. and the spark tracking current A, magnification, etc. It has a protection function of automatically shutting off the corresponding circuit, main line, connection fitting, control panel, etc. or terminal load equipment, electrical equipment, electrical appliances, etc.

[0170] Until the relevant person confirms the alert and resets it, send the alert many times, and in a perfect way, prevent electrical burnout and electrical fire accidents, and it can be an embodiment that implements the function restoration and safety response of the corresponding equipment in real time.

[0171] For example, as data, 83 μsec: It is a common multiple of the power frequencies 50HZ and 60HZ. For example, it is the instantaneous current value measured 12,000 times per second. Single-phase 100V, 50Hz Breaker capacity: 20A Load equipment: Incandescent lamp 200W Rated current: 2A Instantaneous current measurement sampling period: 83 μsec Unit: 1 μsec = 1 / 1,000 msec = 1 / 1,000,000 sec

[0172] The DESCON emergency system, for example, stores in the database, as a constant, the negative instantaneous current -1.4A at 4.15ms after 83 μsec has elapsed from 0A at the start of, for example, the AC reversal axis of the positive current, for example, after 3.32ms. When the circuit of the corresponding system suddenly has a spark tracking phenomenon, if the pre-determined positive and negative current values are 15 - 20 times, send an alert to the relevant person's PC, smartphone, tablet, etc. with a warning signal, and if it is 20 times or more, it can be an embodiment equipped with a judgment means for identifying and automatically shutting off the circuit of the corresponding system.

[0173] In addition, when tracking occurs, an alert is sent to the relevant personnel indicating that automatic shutdown has occurred, and the alert is continuously sent until the relevant personnel confirm and reset it, enabling the safe restoration of the corresponding circuit and ensuring the full functionality of the business or operation in an embodiment.

[0174] The DESCON emergency system, for example, is the average current of -2.0 from 0A at an elapsed time of 3.32ms on the AC reversal axis of positive current, i.e., (-1.4A of negative instantaneous current at 4.15ms with an elapsed time of 83μsec) + (-0.8A of negative current at 4.98ms) + (-2.0A of negative current at 5.81ms) + (-1.7A of negative current at 6.64ms) + (-4.1A of negative current at 7.47ms) / 5 = -2.0. In an embodiment, a sparking and tracking phenomenon with a current magnification of 20 times or more can be detected by using the arbitrarily predefined average current with an instantaneous current of -2.0A as the constant denominator.

[0175] The DESCON emergency system For example, from 0A at an elapsed time of 3.32ms on the AC reversal axis of an arbitrarily defined positive current to the negative instantaneous current of -1.4A at 4.15ms with an elapsed time of 83μsec to the negative current of -0.8A at 4.98ms to the negative current of -2.0A at 5.81ms to the negative current of -1.7A at 6.64ms to the negative current of -4.1A at 7.47ms It is also possible to detect the corresponding current magnification by using -4.1A, which is 0.83ms before the sparking and tracking phenomenon with a current magnification of 15 - 20 times or more and a current of -81.7A at an elapsed time of 8.30ms, as the constant denominator.

[0176] The DESCON emergency system can be configured to detect, for example, a measured current of -1.4 A at the beginning of the elapsed time of 3.32 ms of the negative current after the AC inversion from the positive current mentioned above, and to detect the corresponding magnification of each measured current A with the current magnification having -1.4 as the denominator and the average current of (-1.4 A of the measured current at the elapsed time of 3.32 ms +... + -4.1 A of the measured current at the elapsed time of 7.47 ms) / 5 with the elapsed time of 3.32 ms as the denominator.

[0177] Taking the pre-tracking current of the initial current after AC inversion: -4.3 A as the denominator for each measurement, for each measured current, for example, -4.3 / -4.3 = 1.0 times, -4.6 / -4.3 = 1.07 times, -4.6 / -4.3 = 1.07 times, -4.2 / -4.3 = 0.98 times, -3.5 / -4.3 = 0.81 times. If the magnification of the measured current is 15 times or less set arbitrarily in advance, it is determined to be normal.

[0178] It can be configured such that the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily, is used as the tracking current, and an alert and automatic shut-off are performed at a predetermined magnification.

[0179] For example, it can be configured to determine that it is the current of the tracking phenomenon with a magnification of 15.2 times for the current of -65.5 A / -4.3 A at the elapsed time of 128.235 ms.

[0180] When this determination is made, the corresponding circuit is automatically shut off.

[0181] The current magnification for the above-mentioned automatic shut-off can be arbitrarily determined in advance to be 15 to 20 times or more, for example, it can also be set to automatically shut off at 21 times or more.

[0182] Using the average current before tracking after AC inversion as the denominator of each measured current, for each measured current, for example, (-4.3)+(-4.6)+(-4.6)+(-4.2)+(-3.5) / 5 = -3.5A as the denominator of the constant, for each measured current, for example, -4.3 / -4.2 = 1.01 times, -4.6 / -4.3 = 1.08 times, -4.6 / -4.2 = 1.08 times, -4.2 / -4.2 = 0.99 times, -3.5 / -4.2 = 0.83 times, and it can also be an embodiment where it is determined to be normal if the magnification of the measured current is 15.0 or less set arbitrarily in advance.

[0183] For the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily can be used as the tracking current, and it can be an embodiment where an alert and automatic cutoff are performed at a predetermined magnification.

[0184] For example, it can be an embodiment where it is determined that the current at an elapsed time of 128.235 ms, -65.5A / -4.2A = magnification 15.4 times, is the current of the tracking phenomenon.

[0185] When determined as above, the corresponding circuit is automatically cut off.

[0186] The current magnification for the above automatic cutoff can also be an embodiment where it is arbitrarily determined in advance to be 15 to 20 times or more, for example, automatically cut off at 21 times or more.

[0187] The current immediately before tracking after AC inversion: -3.5A as the denominator of the constant, for each measured current, for example, -4.3 / -3.5 = 1.23 times, -4.6 / -3.5 = 1.31 times, -4.6 / -3.5 = 1.31 times, -4.2 / -3.5 = 1.20 times, -3.5 / -3.5 = 1.0 times, and it can be an embodiment where it is determined to be normal if the magnification of the measured current is 15 times or less set arbitrarily in advance.

[0188] For the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily can be used as the tracking current, and it can be an embodiment where an alert and automatic cutoff are performed at a predetermined magnification.

[0189] For example, it can be an embodiment in which it is determined that the current is a tracking phenomenon current with a magnification of 18.7 times, where the current is -65.5 A / -3.5 A and the elapsed time is 128.235 ms.

[0190] When determined as described above, it can be an embodiment in which the corresponding circuit is automatically shut off.

[0191] The current magnification for the automatic shut-off can be an arbitrarily predetermined value of 15 to 20 times or more. For example, it can be an embodiment in which automatic shut-off can also be performed at 21 times or more.

[0192] Using the pre-tracking current: 3.7 A, which is the current at the beginning after AC inversion, as the denominator for each measurement, the measured currents are, for example, 3.7 / 3.7 = 1.0 times, 3.1 / 3.7 = 0.84 times, 4.2 / 3.7 = 1.14 times, 4.0 / 3.7 = 1.08 times, 4.2 / 3.7 = 1.14 times. If the magnification of the measured current is 15 times or less, which is arbitrarily set in advance, it can be an embodiment in which it is determined to be normal.

[0193] It can be an embodiment in which the measured current magnification, for example, a current of 15.0 to 20 times or more arbitrarily set, is used as the tracking current, and an alert and automatic shut-off are performed at a predetermined magnification.

[0194] For example, it can be an embodiment in which it is determined that the current is a tracking phenomenon current with a magnification of 22.1 times, where the current is 81.9 A / 3.7 A and the elapsed time is 138.4440 ms.

[0195] In the above case, it can be an embodiment in which the corresponding circuit is automatically shut off.

[0196] The current magnification for the automatic shut-off can be an arbitrarily predetermined value of 15 to 20 times or more. For example, it can be an embodiment in which automatic shut-off can also be performed at 21 times or more.

[0197] Using the average current before tracking after AC inversion as the denominator of each measured current, for each measured current, for example, (3.7)+(3.1)+(4.2)+(4.0)+(4.2) / 5 = 3.8A as the constant denominator, for each measured current, for example, 3.7 / 3.8 = 0.96 times, 3.1 / 3.8 = 0.81 times, 4.2 / 3.8 = 1.09 times, 4.0 / 3.8 = 1.04 times, 4.2 / 3.8 = 1.14 times, and it is an embodiment where it can be determined that it is normal if the magnification of the measured current is 15.0 or less set arbitrarily in advance.

[0198] For the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily can be used as the tracking current, and it can be an embodiment where an alert is given and automatic shutdown is performed at a predetermined magnification.

[0199] For example, it can be an embodiment where it is determined that it is a current of a tracking phenomenon with a magnification of 21.3 times, which is 81.9A / 3.8A, at an elapsed time of 138.444 ms.

[0200] When it can be determined as described above, the corresponding circuit can be made into a portable device that automatically shuts off.

[0201] The current magnification for the above automatic shutdown can also be an embodiment where it can be automatically shut off at 21 times or more, which is arbitrarily determined in advance to be 15 to 20 times or more.

[0202] Using the current 4.2A immediately before tracking after AC inversion as the constant denominator, for each measured current, for example, 3.7 / 4.2 = 0.88 times, 3.1 / 4.2 = 0.74 times, 4.2 / 4.2 = 1.0 times, 4.0 / 4.2 = 0.95 times, 4.2 / 4.2 = 1.0 times, and it can be an embodiment where it can be determined that it is normal if the magnification of the measured current is 15 times or less set arbitrarily in advance.

[0203] For the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily can be used as the tracking current, and it can be an embodiment where an alert is given and automatic shutdown is performed at a predetermined magnification.

[0204] For example, an embodiment can be adopted in which it is determined that the current is a tracking phenomenon current with a magnification of 19.5 times, i.e., 81.9 A / 4.2 A, at an elapsed time of 138.444 ms.

[0205] When the determination can be made as described above, an embodiment can be adopted in which the corresponding circuit is automatically shut off.

[0206] The current magnification for the automatic shut-off can be an arbitrarily determined value of 15 to 20 times or more. For example, an embodiment can also be adopted in which automatic shut-off can be achieved at 21 times or more.

[0207] Taking the current before tracking, -0.7 A, as the denominator for each measurement of the current at the beginning after AC inversion, the measured current ratios are, for example, -0.7 - 0.7 = 1.0 times, -1.5 / -0.7 = 2.14 times, -1.0 / -0.7 = 1.43 times, -4.7 / -0.7 = 6.71 times, -4.3 / -0.7 = 6.14 times. When the ratio of the measured current is 15 times or less, which is arbitrarily set in advance, an embodiment can be adopted in which it is determined to be normal.

[0208] An embodiment can be adopted in which the measured current ratio, for example, a current of 15.0 to 20 times or more arbitrarily set, is used as the tracking current, and an alert and automatic shut-off are performed at a predetermined ratio.

[0209] For example, an embodiment can be adopted in which it is determined that the current is a tracking phenomenon current with a magnification of 47.6 times, i.e., -33.3 A / -0.7 A, at an elapsed time of 148.072 ms.

[0210] When the determination can be made as described above, an embodiment can be adopted in which the corresponding circuit is automatically shut off.

[0211] The current magnification for the automatic shut-off can be an arbitrarily determined value of 15 to 20 times or more. For example, an embodiment can also be adopted in which automatic shut-off can be achieved at 21 times or more.

[0212] Using the average current before tracking after AC inversion as the denominator of each measured current, for each measured current, for example, (-0.7)+(-1.5)+(-1.0)+(-4.7)+(-4.3) / 5 = -2.4 A. Using this constant denominator for each measured current, for example, -0.7 / -2.4 = 0.29 times, -1.5 / -2.4 = 0.61 times, -1.0 / -2.4 = 0.41 times, -4.7 / -2.4 = 1.93 times, -4.3 / -2.4 = 1.76 times. It can be an embodiment where it is determined to be normal if the magnification of the measured current is 15.0 or less set arbitrarily in advance.

[0213] It can be an embodiment where the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily is used as the tracking current, and an alert and automatic cutoff are performed at a predetermined magnification.

[0214] For example, it can be an embodiment where it is determined that the current at 148.989 ms of elapsed time, -33.3 A / -2.4 A = magnification 13.6 times, is the current of the tracking phenomenon.

[0215] When it can be determined as described above, it can be an embodiment where the corresponding circuit is automatically cut off.

[0216] It can also be an embodiment where the current magnification for the automatic cutoff is arbitrarily determined in advance to be 15 to 20 times or more, for example, 21 times or more for automatic cutoff.

[0217] Using the current -4.3 A just before tracking after AC inversion as the constant denominator, for each measured current, for example, -0.7 / -4.3 = 0.16 times, -1.5 - / 4.3 = 0.35 times, -1.0 / -4.3 = 0.23 times, -4.7 / -4.3 = 1.09 times, -4.3 / -4.3 = 1.0 times. It can be an embodiment where it is determined to be normal if the magnification of the measured current is 15 times or less set arbitrarily in advance.

[0218] It can be an embodiment where the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily is used as the tracking current, and an alert and automatic cutoff are performed at a predetermined magnification.

[0219] In an embodiment, it can be determined that the current at an elapsed time of 148.989 ms, -33.3 A / -4.3 A = 7.7 times the magnification, is a current of a tracking phenomenon.

[0220] When determined as described above, in an embodiment, the corresponding circuit can be automatically shut off.

[0221] In an embodiment, the current magnification for the automatic shut-off can be arbitrarily determined in advance to be 15 to 20 times or more, for example, 21 times or more for automatic shut-off.

[0222] Taking the pre-tracking current: -1.4 A of the current at the beginning after AC inversion as the denominator for each measurement, for each measured current, for example, -1.4 / -1.4 = 1.0 times, -0.8 / -1.4 = 0.57 times, -2.0 / -1.4 = 1.43 times, -1.7 / -1.4 = 1.21 times, -4.1 / -1.4 = 2.93 times. When the magnification of the measured current is 15 times or less set arbitrarily in advance, in an embodiment, it can be determined to be normal.

[0223] In an embodiment, the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily, can be used as the tracking current, and an alert and automatic shut-off can be performed at a predetermined magnification.

[0224] For example, in an embodiment, it can be determined that the current at an elapsed time of 8.30 ms, -81.7 A / -1.4 A = 58.4 times the magnification, is a current of a tracking phenomenon.

[0225] When determined as described above, in an embodiment, the corresponding circuit can be automatically shut off.

[0226] In an embodiment, the current magnification for the automatic shut-off can be arbitrarily determined in advance to be 15 to 20 times or more, for example, 21 times or more for automatic shut-off.

[0227] Taking the average current before tracking after AC inversion as the denominator of each measured current, for each measured current, for example, (-1.4) + (-0.8) + (-2.0) + (-1.7) + (-4.1) / 5 = -2.0 A. Using this constant denominator, for each measured current, for example, -1.4 / -2.0 = 0.7 times, -0.8 / -2.0 = 0.4 times, -2.0 / -2.0 = 1.0 times, -1.7 / -2.0 = 0.85 times, -4.1 / -2.0 = 2.05 times. It can be an embodiment where it is determined to be normal if the magnification of the measured current is 15.0 or less set arbitrarily in advance.

[0228] It can be an embodiment where the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily is used as the tracking current, and an alert and automatic cutoff are performed at a predetermined magnification.

[0229] For example, in an embodiment where it is determined that the current at an elapsed time of 8.30 ms, -81.7 A / -2.0 A = magnification 40.9 times, is the current of the tracking phenomenon.

[0230] When determining as described above, it can be an embodiment where the corresponding circuit is automatically cut off.

[0231] The current magnification for the above automatic cutoff can be an embodiment where it is arbitrarily determined in advance to be 15 to 20 times or more, for example, it can also be automatically cut off at 21 times or more.

[0232] The current immediately before tracking after AC inversion: -4.1 A. Taking this as the constant denominator, for each measured current, for example, -1.4 / -4.1 = 0.34 times, -0.8 / -4.1 = 0.20 times, -2.0 / -4.1 = 0.49 times, -1.7 / -4.1 = 0.41 times, -4.1 / -4.1 = 1.0 times. It can be an embodiment where it is determined to be normal if the magnification of the measured current is 15 times or less set arbitrarily in advance.

[0233] It can be an embodiment where the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily is used as the tracking current, and an alert and automatic cutoff are performed at a predetermined magnification.

[0234] For example, it can be an embodiment that determines that the current at an elapsed time of 8.30 ms is a current of a tracking phenomenon with a magnification of 19.9 times, i.e., -81.7 A / -4.1 A.

[0235] When determining as described above, it can be an embodiment that automatically shuts off the corresponding circuit.

[0236] The current magnification for the automatic shut-off can be an embodiment that is arbitrarily determined in advance to be 15 to 20 times or more, for example, it can automatically shut off at 21 times or more.

[0237] Taking the current before tracking, -4.9 A, as the denominator for each measurement of the current at the beginning after AC inversion, each measured current, for example, -4.9 / -4.9 = 1.0 times, -4.7 / -4.9 = 0.96 times, -4.9 / -4.9 = 1.0 times, -5.4 / -4.9 = 1.1 times, -4.7 / -4.9 = 0.96 times. If the magnification of the measured current is 15 times or less set arbitrarily in advance, it can be an embodiment that determines it to be normal.

[0238] It can be an embodiment that uses the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily, as the tracking current, and issues an alert and automatically shuts off at a predetermined magnification.

[0239] For example, it can be an embodiment that determines that the current at an elapsed time of 167.660 ms is a current of a tracking phenomenon with a magnification of 19.4 times, i.e., -95.3 A / -4.9 A.

[0240] When determining as described above, it can be an embodiment that automatically shuts off the corresponding circuit.

[0241] The current magnification for the automatic shut-off can be an embodiment that is arbitrarily determined in advance to be 15 to 20 times or more, for example, it can automatically shut off at 21 times or more.

[0242] Using the average current before tracking after AC inversion as the denominator of each measured current, for each measured current, for example, (-4.9) + (-4.7) + (-4.9) + (-5.4) + (-4.7) / 5 = -4.9 A, with a constant denominator, for each measured current, for example, -4.9 / -4.9 = 1.0 times, -4.7 / -4.9 = 0.96 times, -4.9 / -4.9 = 1.0 times, -5.4 / -4.9 = 1.1 times, -4.7 / -4.9 = 0.96 times. An embodiment can be adopted where it is determined to be normal if the magnification of the measured current is 15.0 or less set arbitrarily in advance.

[0243] For the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily can be used as the tracking current, and an embodiment can be adopted where an alert is given and automatic shutdown is performed at a predetermined magnification.

[0244] For example, an embodiment can be adopted where it is determined that the current at an elapsed time of 167.660 ms, -95.3 A / -4.9 A = magnification 19.4 times, is the current of the tracking phenomenon.

[0245] When determining as described above, an embodiment can be adopted where the corresponding circuit is automatically shut off.

[0246] For the current magnification of the above automatic shutdown, an embodiment can be adopted where it is arbitrarily determined in advance to be 15 to 20 times or more, for example, automatic shutdown can be performed at 21 times or more.

[0247] The current immediately before tracking after AC inversion: -4.7 A. Using this as a constant denominator, for each measured current, for example, -4.9 / -4.7 = 1.04 times, -4.7 / -4.7 = 1.0 times, -4.9 / -4.7 = 1.04 times, -5.4 / -4.7 = 1.15 times, -4.7 / -4.7 = 1.0 times. An embodiment can be adopted where it is determined to be normal if the magnification of the measured current is 15 times or less set arbitrarily in advance.

[0248] For the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily can be used as the tracking current, and an embodiment can be adopted where an alert is given and automatic shutdown is performed at a predetermined magnification.

[0249] For example, it can be an embodiment that determines that the current at an elapsed time of 167.660 ms, -95.3 A / -4.7 A = 20.3 times the magnification, is a current of a tracking phenomenon.

[0250] When determined as described above, it can be an embodiment that automatically shuts off the corresponding circuit.

[0251] The current magnification for the automatic shut-off can be an arbitrarily determined value of 15 to 20 times or more in advance. For example, it can be an embodiment that can automatically shut off at 21 times or more.

[0252] Using the current before tracking, -1.4 A, as the denominator for each measurement of the current at the beginning after AC inversion, each measured current, for example, -1.4 / -1.4 = 1.0 times, -0.8 / -1.4 = 0.57 times, -2.0 / -1.4 = 1.43 times, -1.7 / -1.4 = 1.21 times, -4.1 / -1.4 = 2.93 times. If the magnification of the measured current is 15 times or less, which is arbitrarily set in advance, it can be an embodiment that determines it to be normal.

[0253] It can be an embodiment that uses the measured current magnification, for example, a current of 15.0 to 20 times or more arbitrarily set, as the tracking current, and issues an alert and automatically shuts off at a predetermined magnification.

[0254] For example, it can be an embodiment that determines that the current at an elapsed time of 8.30 ms, -81.7 A / -1.4 A = 58.4 times the magnification, is a current of a tracking phenomenon.

[0255] In the above case, it can be an embodiment that automatically shuts off the corresponding circuit.

[0256] The current magnification for the automatic shut-off can be an arbitrarily determined value of 15 to 20 times or more in advance. For example, it can be an embodiment that can automatically shut off at 21 times or more.

[0257] Using the average current before tracking after AC inversion as the denominator of each measured current, for each measured current, for example, (-1.4)+(-0.8)+(-2.0)+(-1.7)+(-4.1) / 5 = -2.0 A. With a constant denominator, for each measured current, for example, -1.4 / -2.0 = 0.7 times, -0.8 / -2.0 = 0.4 times, -2.0 / -2.0 = 1.0 times, -1.7 / -2.0 = 0.85 times, -4.1 / -2.0 = 2.05 times. It can be an embodiment where it is determined to be normal if the magnification of the measured current is 15.0 or less set arbitrarily in advance.

[0258] For the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily can be used as the tracking current, and it can be an embodiment where an alert and automatic cutoff are performed at a predetermined magnification.

[0259] For example, it can be an embodiment where it is determined that the current at an elapsed time of 8.30 ms, -81.7 A / -2.0 A = magnification 40.9 times, is a current of the tracking phenomenon.

[0260] When determining as described above, it can be an embodiment where the corresponding circuit is automatically cut off.

[0261] The current magnification for the above automatic cutoff can be an embodiment where it can be automatically cut off at 15 to 20 times or more, arbitrarily determined in advance, for example, 21 times or more.

[0262] The current immediately before tracking after AC inversion: -4.1 A. Using this as a constant denominator, for each measured current, for example, -1.4 / -4.1 = 0.34 times, -0.8 / -4.1 = 0.20 times, -2.0 / -4.1 = 0.49 times, -1.7 / -4.1 = 0.41 times, -4.1 / -4.1 = 1.0 times. It can be an embodiment where it is determined to be normal if the magnification of the measured current is 15 times or less set arbitrarily in advance.

[0263] For the measured current magnification, for example, a current of 15.0 to 20 times or more set arbitrarily can be used as the tracking current, and it can be an embodiment where an alert and automatic cutoff are performed at a predetermined magnification.

[0264] For example, an embodiment can be adopted in which it is determined that the current is a tracking phenomenon current with a magnification of 19.9 times, i.e., a current of -81.7 A / -4.1 A at an elapsed time of 8.30 ms.

[0265] When determined as described above, an embodiment can be adopted in which the corresponding circuit is automatically shut off.

[0266] For the automatic shut-off current magnification, an embodiment can be adopted in which it is arbitrarily determined in advance to be 15 to 20 times or more, for example, 21 times or more for automatic shut-off.

[0267] Regarding the elapsed time of positive current A from 0.83 ms to 2.49 ms.

[0268] The elapsed time is from 0.83 ms to 2.49 ms for positive current A, and it refers to the magnification of each measured current.

[0269] Regarding current A with an elapsed time from 83 ms to 2.49.

[0270] The elapsed time is 0.83 ms: 2.1 A, 1.66 ms: 2.3 A, and 2.49 ms: 1.0 A.

[0271] The inversion of the positive current is 0 A, and the average current value at the previous elapsed time of 2.49 ms is 1.8 A.

[0272] For example, with a negative current of -1.4 A at an elapsed time of 4.15 ms of negative current A, starting from the inversion axis of 0 A from positive current to negative current, taking the -1.4 A at the initial elapsed time of 4.15 ms as the denominator, the current magnification of the measured current at each measurement time is calculated to determine spark tracking. An embodiment can be adopted in which an alert is sent and automatic shut-off is performed at an arbitrarily determined in-advance current magnification. The above may be a negative current that has reversed from the positive current of the alternating current.

[0273] The measured elapsed times are as follows: elapsed time 4.15 ms: -1.4 A, elapsed time 4.98 ms: -0.8 A, elapsed time 5.81 ms: -2.0 A, elapsed time 6.64 ms: -1.7 A, elapsed time 7.47 ms: -4.1 A.

[0274] For each of the elapsed times of negative current A from 4.15 ms -1.4 A to 7.47 ms -4.7 A with an average current of -2.0 A, for each current magnification of the elapsed times from 4.15 ms to 7.47 ms.

[0275] For example, from the inversion axis of 0 A from positive current to negative current, the currents from -1.4 A at an elapsed time of 4.15 ms to 4.1 A at an elapsed time of 7.47 ms are added, divided by 5 after addition, and using the average current of -2.0 A as the denominator, it is possible to form an embodiment for determining spark tracking by the average current magnification. It is possible to form an embodiment for alert transmission and automatic switching off at an arbitrarily determined current magnification in advance. The above may be a negative current that has reversed from the positive current of an alternating current.

[0276] (Measured elapsed time 4.15 ms: (-1.4 A + measured elapsed time 4.98 ms: -0.8 A + measured elapsed time 5.81 ms: -2.0 A + measured elapsed time 6.64 ms: -1.7 A + measured elapsed time 7.47 ms: -4.1 A)) = average current -2.0 A.

[0277] It is possible to form an embodiment for detecting the current magnification with each current of -1.4 A, -0.8 A, -2.0 A, -1.7 A, -4.1 A using the average current of -2.0 as the denominator. It is possible to form an embodiment for alert transmission and automatic switching off at an arbitrarily determined current magnification in advance. The above may be a negative current that has reversed from the positive current of an alternating current.

[0278] Detect, for example, -4.1 A at an elapsed time of 7.47 ms, which is immediately before an arbitrarily determined current magnification of 15 times or more of negative current A. Take the current magnification of -81.7 A at an elapsed time of 8.30 ms as 19.9 times, detect each current A in elapsed time units, and calculate the current magnification.

[0279] For example, from the inversion axis 0A from a positive current to a negative current, a current value of 15 times or more of the current magnification is detected, and using the current value -4.1 A at an elapsed time of 7.47 ms before the current value -81.7 A at an elapsed time of 8.3 ms as the denominator, a spark tracking can be determined according to the current magnification of each measured current. An embodiment can be adopted in which an alert is transmitted at an arbitrarily determined current magnification in advance, and automatic switching-off is performed at 20 times or more. The above may be a negative current that has reversed from the positive current of the alternating current.

[0280] The measured elapsed times 4.15 ms: -1.4 A + elapsed time 4.98 ms: -0.8 A + elapsed time 5.81 ms: -2.0 A + elapsed time 6.64 ms: -1.7 A + elapsed time 7.47 ms: -4.1 A are as follows.

[0281] An embodiment can be adopted in which, for the above negative current with an elapsed time of 8.30 ms to 9.296 ms, for example, using the currents -1.4 A, S2 current -2.0 A, S3 -4.1 A as the denominator, a circuit corresponding to the spark tracking with a current magnification of 15 times or more arbitrarily determined in advance is detected and judged. An embodiment can be adopted in which, for example, automatic switching-off is performed at 20 times or more of an arbitrarily determined current magnification in advance. An example of the current magnification of each current is as shown in FIG. 23.

[0282] The DESCON emergency system can be configured to detect the current using the above currents: -1.4 A, current: 2.0 A, current: -4.1 A as the denominator, and determine that it is spark tracking when the magnification of each current A is 15 times or more of an arbitrarily determined current magnification in advance. An embodiment can be adopted in which an alert is transmitted and automatic switching-off is performed at 20 times or more.

[0283] With a negative current A of -4.3 A at an elapsed time of 127.82 ms, for example, starting from the inversion axis of 0 A from the positive current to the negative current, taking -4.3 A at the initial elapsed time of 127.82 ms as the denominator, the current magnification of the measured current at each measurement time is calculated to form an embodiment for determining spark tracking. It can be an embodiment of alert transmission and automatic implementation of interruption at an arbitrarily determined current magnification in advance. The above may be a negative current that has reversed from the positive current of the alternating current.

[0284] The measured elapsed times are as follows: 127.82 ms: -4.3 A, 127.903 ms: -4.6 A, 127.986 ms: -4.6 A, 128.069 ms: -4.2 A, 128.152 ms: -3.5 A.

[0285] Regarding the average current of -4.2 A from -4.3 A at an elapsed time of 127.82 ms to -3.5 A at an elapsed time of 128.152 ms of the negative current A, for each current magnification from an elapsed time of 127.82 ms to 128.152 ms.

[0286] For example, starting from the inversion axis of 0 A from the positive current to the negative current, the currents from -4.3 A at an elapsed time of 127.82 ms to -3.5 A at an elapsed time of 128.152 ms are added, divided by 5 after addition, and taking the average current of -4.2 A as the denominator, it can form an embodiment for determining spark tracking by the average current magnification. It can be an embodiment of alert transmission and automatic implementation of interruption at an arbitrarily determined current magnification in advance. The above may be a negative current that has reversed from the positive current of the alternating current.

[0287] The sum of the measured each (elapsed time 128.82 ms: -4.3 A + elapsed time 127.903 ms: -4.6 A + elapsed time 127.986 ms: -4.6 A + elapsed time 128.069 ms: -4.2 A + elapsed time 128.152 ms: -3.5 A) = average current -4.3 A.

[0288] An embodiment can be adopted in which the current magnification is detected by using -4.3 A, -4.6 A, -4.6 A, -4.2 A, and -3.5 A as each current and using an average current of -4.2 as the denominator. An embodiment can be adopted in which an alert is transmitted and automatic switching-off is performed at an arbitrarily determined current magnification in advance. The above may be a negative current that is the reverse of the positive current of the alternating current.

[0289] Detect -4.1 A at an elapsed time of, for example, 7.47 ms immediately before a current magnification of 15 times or more of a negative current A that is arbitrarily determined in advance, set the current magnification to 19.9 times for -81.7 A at an elapsed time of 8.30 ms, detect each current A in units of elapsed time, and calculate the current magnification.

[0290] For example, an embodiment can be adopted in which a current value of 15 times or more of the current magnification is detected from the inversion axis of 0 A from the positive current to the negative current, and spark tracking is determined based on the current magnification of each measured current with the current value of -4.1 A at an elapsed time of 7.47 ms before the current value of -81.7 A at an elapsed time of 8.3 ms as the denominator. An embodiment can be adopted in which an alert is transmitted at an arbitrarily determined current magnification in advance and automatic switching-off is performed at 20 times or more. The above may be a negative current that is the reverse of the positive current of the alternating current.

[0291] The measured elapsed times are as follows: 128.82 ms: -4.3 A, 127.903 ms: -4.6, 127.986 ms: -4.6 A, 128.069 ms: -4.2 A, 128.152 ms: -3.5 A.

[0292] An embodiment can be adopted in which a circuit corresponding to a spark tracking system of 15 times or more of an arbitrarily determined current magnification in advance is detected and determined using, for example, -4.3 A, -4.2 A, and -3.5 A as the denominator for the elapsed time of 9960 ms to 128.152 ms c of the negative current. An embodiment can be adopted in which automatic switching-off is performed at 20 times or more of an arbitrarily determined current magnification in advance. An example of each current is as shown in FIG. 26.

[0293] The DESCON emergency system detects currents from 1545 to 1549 using the above-mentioned S1 current: -4.3 A, S2 current: -4.2 A, and S3 current: -3.5 A as the denominators. The magnification factor of each current A is, for example, determined arbitrarily in advance to be 15 times or more for spark tracking and judgment means, and it is characterized by alert transmission, and control means for automatic cutoff at 20 times or more.

[0294] For example, by multiplying the elapsed time of the positive current A, 138.029 ms, by 3.7, starting from the inversion axis of 0 A from the positive current to the negative current, taking 3.7 A at the initial elapsed time of 138.029 ms as the denominator, calculating the current magnification factor of the measured current at each measurement time, and determining means for spark tracking. It is characterized by alert transmission at an arbitrarily determined current magnification factor in advance and means for automatic cutoff. The above may be a negative current that has reversed from the positive current of the alternating current.

[0295] The measured elapsed times are as follows: 138.029 ms: 3.7 A, 138.112 ms: 3.1 A, 138.195 ms: 4.2 A, 138.278 ms: 4.0 A, 138.361 ms: 4.2 A.

[0296] Regarding the average current of 3.8 A from the elapsed time of the positive current A, 138.029 ms: 3.7 A to 138.361 ms: 4.2 A, and for each current magnification factor from the elapsed time of 138.029 ms to 138.361 ms of S2.

[0297] For example, starting from the inversion axis of 0 A from the positive current to the negative current, adding the currents from 3.7 A at the elapsed time of 138.029 ms to 4.2 A at the elapsed time of 138.361 ms, dividing by 5 after addition, taking the average current of 3.8 A as the denominator, and determining means for spark tracking by the average current magnification factor. It is characterized by alert transmission at an arbitrarily determined current magnification factor in advance and means for automatic cutoff. The above may be a negative current that has reversed from the positive current of the alternating current.

[0298] The measured values of each (elapsed time 138.029 ms: 3.7 A + elapsed time 138.112 ms: 3.1 A + elapsed time 138.195 ms: 4.2 A + elapsed time 138.278 ms: 4.0 A + elapsed time 138.361 ms: 4.2 A) = average current - 3.8 A.

[0299] Characterized by a determination means for detecting a current magnification with each current of 3.7 A, 3.1 A, 4.2 A, 4.0 A, 4.2 A using an average current of 3.8 as the denominator, and characterized by means for transmitting an alert and automatically performing shut-off at an arbitrarily determined current magnification in advance. The above may be a negative current that is the reverse of the positive current of an alternating current.

[0300] Detect, for example, 4.2 A at an elapsed time of 138.361 ms immediately before an arbitrarily determined current magnification of 15 times or more of the positive current A, set the current magnification of 81.9 A at an elapsed time of 138.444 ms to 19.5 times, detect each current A in elapsed time units, and calculate the current magnification.

[0301] Characterized by means for detecting a current value with a current magnification of 15 times or more from the inversion axis 0 A from a positive current to a negative current, and judging spark tracking based on the current magnification of each measured current with 4.2 A at an elapsed time of 138.361 ms before 81.9 A at an elapsed time of 138.444 ms as the denominator, and characterized by means for transmitting an alert at an arbitrarily determined current magnification in advance and automatically performing shut-off at 20 times or more. The above may be a negative current that is the reverse of the positive current of an alternating current.

[0302] The measured elapsed times 138.029 ms: 3.7 A, 138.112 ms: 3.1 A, 138.195 ms: 4.2 A, 138.278 ms: 4.0 A, 138.361 ms: 4.2 A are as follows.

[0303] For the elapsed time of positive current from 138.029 ms: 3.7 A to 138.361 ms, for example, using the S1 current of 3.7 A, S2 current of 3.8 A, and S3 current of 4.2 A as the denominator, a circuit corresponding to spark tracking with a current magnification of 15 times or more, which is arbitrarily determined in advance, is detected by the determination means, and means for automatically shutting off at a current magnification of 20 times or more, which is arbitrarily determined in advance, is characterized. An example of the current magnification of each of the S1, S2, and S3 currents is as shown in FIGS. 29 and 30.

[0304] The DESCON emergency system detects currents from 1668 to 1690 using the above-mentioned S1 current of 3.7 A, S2 current of 3.8 A, and S3 current of 4.2 A as the denominator, and is characterized by means for determining that the magnification of each current A is, for example, 15 times or more of an arbitrarily determined current magnification in advance for spark tracking, and transmitting an alert, and is characterized by control means for automatically shutting off at 20 times or more.

[0305] With the negative current A of -0.7 A at the elapsed time of 147.657 ms, for example, starting from the inversion axis of 0 A from the positive current to the negative current, using -0.7 A at the elapsed time of 147.657 ms as the denominator, the current magnification of the measured current at each measurement time is calculated to determine spark tracking, and means for transmitting an alert and automatically shutting off at an arbitrarily determined current magnification in advance is characterized. The above may be a negative current that has reversed from the positive current of an alternating current.

[0306] The measured elapsed times are as follows: 147.657 ms: -0.7 A, 147.740 ms: -1.5 A, 147.823 ms: -1.0 A, 147.906 ms: -4.7 A, 147.989 ms: -4.3 A.

[0307] Regarding the average current of -2.4 A of the negative current A from the elapsed time of 147.657 ms - 0.7 A to 147.989 ms - 4.3 A and the current magnification of each of the S2 currents from the elapsed time of 147.657 ms to 147.989 ms.

[0308] For example, from the inversion axis 0A from positive current to negative current, the currents from -0.7A at an elapsed time of 147.657 ms to 4.3A at an elapsed time of 147.989 ms are added, divided by 5 after addition, and the average current -2.4A is used as the denominator to determine spark tracking by the average current magnification. It is characterized by means for alert transmission and automatic switching off at an arbitrarily predetermined current magnification. The above may be a negative current that has reversed from the positive current of the alternating current.

[0309] The measured values are (current at elapsed time 147.657 ms: -0.7A + current at elapsed time 147.740 ms: -1.5A + current at elapsed time 147.823 ms: -1.0A + current at elapsed time 147.906 ms: -4.7A + current at elapsed time 147.989 ms: -4.3A) / 5 = average current -2.4A.

[0310] It is characterized by means for detecting the current magnification with each current of -0.7A, -1.5A, -1.0A, -4.7A, -4.3A using the average current -2.4 as the denominator, and means for alert transmission and automatic switching off at an arbitrarily predetermined current magnification. The above may be a negative current that has reversed from the positive current of the alternating current.

[0311] Detect, for example, -4.3A at an elapsed time of 147.989 ms immediately before an arbitrarily predetermined current magnification of 15 times or more of the negative current A, set the current magnification of -33.3A at an elapsed time of 148.072 ms to 7.7 times, detect each current A in units of elapsed time, and calculate the current magnification.

[0312] For example, from the inversion axis 0A from positive current to negative current, detect current values with a current magnification of 15 times or more, and use the current value -4.3A at an elapsed time of 147.989 ms before the current value -33.3A at an elapsed time of 148.072 ms as the denominator to determine spark tracking by the current magnification of each measured current. It is characterized by means for alert transmission at an arbitrarily predetermined current magnification and automatic switching off at 20 times or more. The above may be a negative current that has reversed from the positive current of the alternating current.

[0313] The measured average current is -2.4 A, which is calculated as follows: (Elapsed time 147.657 ms: -0.7 A + Elapsed time 147.740 ms: -1.5 A + Elapsed time 147.823 ms: -1.0 A + Elapsed time 147.906 ms: -4.7 A + Elapsed time 147.989 ms: -4.3 A) / 5.

[0314] Characterized by a detection and judgment means for a spark tracking system corresponding to a current magnification of 15 times or more, which uses the current values in the elapsed time of negative current from 148.072 ms to 149.898 ms as the denominator, and characterized by a means for automatically shutting off at 20 times or more of a preset arbitrary current magnification. An example of the current magnification of each current of S1, S2, and S3 is as shown in FIGS. 33 and 34.

[0315] The DESCON emergency system detects a current of 100 to 113 using the above current value as the denominator, and is characterized by a spark tracking and judgment means with a magnification of each current A of 15 times or more of a preset arbitrary current magnification, and transmits an alert, and is characterized by a control means for automatically shutting off at 20 times or more.

[0316] Characterized by a means for calculating the current magnification of the measured current at each measurement time using, for example, the 4.6 A at the elapsed time of 158.530 ms of positive current A as the denominator from the inversion axis of 0 A from positive current to negative current, and judging spark tracking, and characterized by a means for transmitting an alert and automatically shutting off at a preset arbitrary current magnification. The above may be a negative current that has reversed from a positive current of an alternating current.

[0317] The measured elapsed times and corresponding currents are as follows: Elapsed time 158.530 ms: 4.6 A, Elapsed time 158.613 ms: 4.4 A, Elapsed time 158.696 ms: 4.3 A, Elapsed time 158.779 ms: 4.1 A, Elapsed time 158.862 ms: 4.8 A.

[0318] Regarding the average current of 4.4 A for the positive current A with an elapsed time of 158.530 ms to 158.862 ms and the current magnification of each elapsed time of 158.530 ms to 158.862 ms for S2.

[0319] For example, from the inversion axis 0A from positive current to negative current, the currents from 4.6A at an elapsed time of 158.530 ms to 4.8A at an elapsed time of 158.862 ms are added, divided by 5 after addition, and the average current 4.4A is used as the denominator to determine spark tracking by the average current magnification. It is characterized by means for alert transmission and automatic switching off at an arbitrarily determined current magnification in advance. The above may be a negative current that has reversed from the positive current of the alternating current.

[0320] The measured values are (4.6A at an elapsed time of 158.530 ms + 4.4A at an elapsed time of 158.613 ms + 4.3A at an elapsed time of 158.696 ms + 4.1A at an elapsed time of 158.779 ms + 4.8A at an elapsed time of 158.862 ms) / 5 = average current 4.4A.

[0321] It is characterized by means for detecting the current magnification by using the average current 4.4A as the denominator for each current of 4.6A, 4.4A, 4.3A, 4.1A, and 4.8A, and means for alert transmission and automatic switching off at an arbitrarily determined current magnification in advance. The above may be a negative current that has reversed from the positive current of the alternating current.

[0322] Detect, for example, 4.8A at an elapsed time of 158.862 ms immediately before an arbitrarily determined current magnification of 15 times or more of the positive current A, set the current magnification of 56.4A at an elapsed time of 158.945 ms to 11.8 times, detect each current A in units of elapsed time, and calculate the current magnification.

[0323] For example, from the inversion axis 0A from positive current to negative current, detect a current value with a current magnification of 15 times or more, and use 4.8A at an elapsed time of 158.862 ms before 56.4A at an elapsed time of 158.945 ms as the denominator to determine spark tracking by the current magnification of each measured current. It is characterized by means for alert transmission at an arbitrarily determined current magnification in advance and automatic switching off at 20 times or more. The above may be a negative current that has reversed from the positive current of the alternating current.

[0324] The measured elapsed times 158.530 ms: 4.6 A, elapsed time 158.613 ms: 4.4 A, elapsed time 158.696 ms: 4.3 A, elapsed time 158.779 ms: 4.1 A, elapsed time 158.862 ms: 4.8 A are as follows.

[0325] Using the current values of the elapsed times of the negative current from 158.945 ms to 160.190 ms as the denominator, a circuit corresponding to the spark tracking system with a current magnification of 15 times or more arbitrarily determined in advance is used as a detection and judgment means, and means for automatically shutting off at 20 times or more arbitrarily determined in advance is characterized. An example of the current magnification of each current is as shown in FIGS. 38 and 39.

[0326] The DESCON emergency system detects a current of 100 to 113 using the above current value as the denominator, and the magnification of each current A is characterized by spark tracking and judgment means at 15 times or more of the current magnification arbitrarily determined in advance, and control means for automatically shutting off at 20 times or more.

[0327] Due to -4.9 A of the elapsed time of 167.162 ms of the negative current A, for example, starting from the inversion axis 0 A from the positive current to the negative current, using -4.9 A of the initial elapsed time: 167.162 ms as the denominator, calculating the current magnification of the measured current at each measurement time, and determining means for spark tracking, and means for alert transmission and automatic shut-off at an arbitrarily determined current magnification in advance. The above may be a negative current that has reversed from the positive current of the alternating current.

[0328] The measured elapsed times 167.162 ms: -4.9 A, elapsed time 167.245 ms: -4.7 A, elapsed time 167.328 ms: -4.9 A, elapsed time 167.411 ms: -5.4 A, elapsed time 167.494 ms: -4.7 A are as follows.

[0329] For the average current -4.9 A of the elapsed times of the negative current A from 167.162 ms - 4.9 A to 167.494 ms - 4.7 A, for each current magnification of the elapsed times from 167.162 ms to 167.494 ms.

[0330] For example, from the inversion axis 0A from positive current to negative current, the currents from -4.9A at an elapsed time of 167.162 ms to 4.7A at an elapsed time of 167.494 ms are added, divided by 5 after addition, and the average current -4.9A is used as the denominator to determine spark tracking by the average current magnification. It is characterized by means for alert transmission and automatic implementation of interruption at an arbitrarily determined current magnification in advance. The above may be a negative current that is the reverse of the positive current of the alternating current.

[0331] The measured values are (current at an elapsed time of 167.162 ms: -4.9A + current at an elapsed time of 167.245 ms: -4.7A + current at an elapsed time of 167.328 ms: -4.9A + current at an elapsed time of 167.411 ms: -5.4A + current at an elapsed time of 167.494 ms: -4.7A) / 5 = average current -4.9A.

[0332] It is characterized by means for detecting the current magnification with the average current -4.9A as the denominator for each current of -4.9A, -4.7A, -4.9A, -5.4A, -4.7A, and is characterized by means for alert transmission and automatic implementation of interruption at an arbitrarily determined current magnification in advance. The above may be a negative current that is the reverse of the positive current of the alternating current.

[0333] Detect, for example, -4.9A at an elapsed time of 167.162 ms immediately before an arbitrarily determined current magnification of 15 times or more for the negative current A, set the current magnification at an elapsed time of 167.660 ms to 20.3 times for -95.3A, detect each current A in elapsed time units, and calculate the current magnification.

[0334] For example, from the inversion axis 0A from positive current to negative current, detect current values with a current magnification of 15 times or more, and use the current value -4.7A at an elapsed time of 167.494 ms before the current value -95.3A at an elapsed time of 167.660 ms as the denominator to determine spark tracking by the current magnification of each measured current. It is characterized by means for alert transmission at an arbitrarily determined current magnification in advance and automatic implementation of interruption at 20 times or more. The above may be a negative current that is the reverse of the positive current of the alternating current. 2) The measured elapsed times are as follows: elapsed time 4.15 ms: -1.4 A, elapsed time 4.98 ms: -0.8 A, elapsed time 5.81 ms: -2.0 A, elapsed time 6.64 ms: -1.7 A, elapsed time 7.47 ms: -4.1 A.

[0335] Using the current values of the elapsed times of the negative current from 8.30 ms to 9.296 ms as the denominator, a system detection and judgment means for spark tracking with a current magnification of 15 times or more arbitrarily determined in advance is characterized, and a means for automatically shutting off at 20 times or more arbitrarily determined in advance is characterized. An example of the current magnification of each current of S1, S2, and S3 is as shown in FIGS. 42 and 43.

[0336] The DESCON emergency system detects the current using the above current value as the denominator, and is characterized by a means for determining spark tracking when the magnification of each current A is 15 times or more arbitrarily determined in advance, for example, and for transmitting an alert, and a control means for automatically shutting off at 20 times or more.

[0337] With 2.9 A at the elapsed time of 177.039 ms of the positive current A, 1) for example, starting from the inversion axis of 0 A from the positive current to the negative current, a means for calculating the current magnification of the measured current at each measurement time with 2.9 A at the initial elapsed time of 177.039 ms as the denominator to determine spark tracking is characterized, and a means for transmitting an alert and automatically shutting off at an arbitrarily determined current magnification in advance is characterized. The above may be a negative current that is the reverse of the positive current of the alternating current.

[0338] The measured elapsed times are as follows: elapsed time 177039 ms: 2.9 A, elapsed time 177.122 ms: 4.5 A, elapsed time 177.205 ms: 3.9 A, elapsed time 177.288 ms: 3.6 A, elapsed time 177.371 ms: 3.6 A, elapsed time 177.454 ms: 8.9 A.

[0339] For the average current of 4.6 A from 2.9 A at the elapsed time of 177.039 ms to 8.9 A at 177.454 ms of the positive current A and for each current magnification from the elapsed time of 177.039 ms to 177.454 ms of S2.

[0340] For example, from the inversion axis 0A from positive current to negative current, the currents from 2.9A at an elapsed time of 177.039 ms to 8.9A at an elapsed time of 177.454 ms are added, divided by 6 after addition, and the average current 4.6A is used as the denominator to determine spark tracking by the average current magnification. It is characterized by means for alert transmission and automatic switching off at an arbitrarily determined current magnification in advance. The above may be a negative current that is inverted from the positive current of the alternating current.

[0341] Measured each (elapsed time 177039 ms: 2.9A + elapsed time 177.122 ms: 4.5A + elapsed time 177.205 ms: 3.9A + elapsed time 177.288 ms: 3.6A + elapsed time 177.371 ms: 3.6A + elapsed time 177.454 ms: 8.9A) / 6 = average current 4.6A.

[0342] It is characterized by a judging means for detecting the current magnification by using each current of 2.9A, 4.5A, 3.9A, 3.6A, 3.6A, 8.9A with the average current 4.6A as the denominator, and is characterized by means for alert transmission and automatic switching off at an arbitrarily determined current magnification in advance. The above may be a negative current that is inverted from the positive current of the alternating current.

[0343] Detect, for example, 8.9A at an elapsed time of 177.454 ms immediately before an arbitrarily determined current magnification of 15 times or more of the positive current A, set the current magnification of -81.7A at an elapsed time of 177.454 ms to 7.6 times, detect each current A in units of elapsed time, and calculate the current magnification.

[0344] For example, from the inversion axis 0A from positive current to negative current, detect a current value with a current magnification of 15 times or more, and use 8.9A at an elapsed time of 177.454 ms before the current value of 67.2A at an elapsed time of 177.537 ms as the denominator to judge spark tracking by the current magnification of each measured current. It is characterized by means for alert transmission at an arbitrarily determined current magnification in advance and automatic switching off at 20 times or more. The above may be a negative current that is inverted from the positive current of the alternating current.

[0345] The measured elapsed times are as follows: elapsed time 177039 ms: 2.9 A, elapsed time 177.122 ms: 4.5 A, elapsed time 177.205 ms: 3.9 A, elapsed time 177.288 ms: 3.6 A, elapsed time 177.371 ms: 3.6 A, elapsed time 177.454 ms: 8.9 A.

[0346] Using the current values within the elapsed time of 8.30 ms to 9.296 ms of negative current as the denominator, a circuit detection and judgment means for spark tracking with a current magnification of 15 times or more, which is arbitrarily determined in advance, is characterized. A means for automatically shutting off at 20 times or more, which is arbitrarily determined in advance, is characterized. An example of the current magnification of each current of S1, S2, S3 is as shown in FIGS. 46 and 47.

[0347] The DESCON emergency system detects a current of 100 to 113 using the above current value as the denominator, and is characterized by a spark tracking and judgment means with a magnification of each current A of 15 times or more, which is arbitrarily determined in advance, and transmits an alert. A control means for automatically shutting off at 20 times or more is characterized.

[0348] In the DESCON emergency system, for the program of joule heat, the current value due to looseness, gaps, etc. of connection fittings such as in the panel, circuit, etc. is constant, and due to the decrease in the electrical conduction area, electrical resistance heat is generated and rises, etc. For the electrical short-circuit heat, temperature sensors are installed for each circuit of connection fittings, terminals, etc. in low-voltage electric lamps, power distribution boards, main lines, electric lamps, power distribution boards for power, electric lamps, control panels for power, etc. Also, temperature sensors are installed for connection fittings, sockets, load equipment, etc. of each cable, and for each circuit in the remote panel of the distributor. If the allowable temperature of each cable is exceeded or the attention temperature, which is arbitrarily determined in advance, is reached, an attention signal is transmitted as an alert to the relevant personnel. When the attention temperature reaches a preset temperature and the set time has elapsed, or when the arbitrarily determined warning temperature is exceeded, the corresponding circuit can be automatically shut off.

[0349] The DESCON emergency system, regardless of the above-mentioned panels, connection appliances, etc. such as cubicles, switchboards, distribution boards, control panels, terminal outlets, refrigerators, freezers, conveyors, welders, mobile control panels, PCs, servers, network devices, inspection operator devices, etc. in houses, condominiums, offices, commercial facilities, hospitals, hotels, research institutes, exhibitions, exhibition halls, data centers, logistics centers, warehouses, factories, construction sites, airports, ships, substations, power plants, solar power generation, wind power generation, etc., for example, power cables such as installed and fixed or temporary, movable, mobile, etc. are deformed, narrowed, bent, stretched, pressed, etc. due to compression, tension, sharp-angle bending, etc. by heavy objects, and the current-carrying conduction area is deformed, narrowed, bent, stretched, pressed, etc. resulting in disconnection of parts, etc., and reduction, poor contact, etc., causing Joule heat to be generated in the corresponding part, and detecting a temperature arbitrarily set in advance with respect to the allowable temperature of the above-mentioned electrical materials. For example, 1 to n Joule heat detection devices are installed in main lines, wiring, cables, etc. other than the above-mentioned panels at arbitrary positions where Joule heat is likely to be generated in main lines, wiring, cables, etc. due to, for example, narrowing of the conduction area, partial disconnection, etc. caused by pressing, bending, stretching, etc. of main lines, wiring, cables, etc., and installed in each member of the panel or main lines, wiring, cables, etc. outside the panel. When the temperature of abnormal temperature conduction due to disconnection, poor contact, etc. of the power cable of the above-mentioned equipment becomes high and reaches the arbitrarily set allowable temperature in advance, it is possible to implement a form in which voice, numerical values, and images are alerted and transmitted to the PCs, tablets, and smartphones of the relevant personnel as warning temperatures, and the alert incoming sound rings until the relevant personnel confirm and reset it to prevent the relevant personnel from overlooking the confirmation.

[0350] The summary of the DESCON emergency system is as follows: for cables such as KIV cables and CV cables, the maximum allowable temperatures are set in advance as attention temperatures and alarm temperatures, and real-time alerts are sent to the PCs, tablets, smartphones, etc. of relevant personnel in the form of voice, images, numerical values, etc. For circuit breakers, etc. in the switchboards, distribution boards, control panels, main lines, circuits, etc. of the corresponding equipment, they are automatically shut off, or for example, for products, manufacturing, etc. by computer programs such as AI and IoT, and for commercial facilities where a large number of people gather such as logistics centers, large refrigerators, refrigerators, terminal buildings, hotels, etc., for lighting, elevators, etc., for data centers such as important data and research test results, for substations of infrastructure, etc., and for various corresponding equipment such as trains and ships in transportation, electrical equipment, etc., when the corresponding terminal equipment, electrical equipment, etc. need to be shut down according to a pre-determined program, the switchboards, distribution boards, control panels, main lines, circuits, circuit breakers, etc. are configured with system-specific remote devices, etc., and the system composed of cloud servers, LAN, etc. is based on an emergency response protection program with system-specific remote devices, etc., and cloud servers, LAN, etc. The remote device of the corresponding switchboard, distribution board, control panel, etc. sends a signal to the protection stop device, and the control, etc. of the batch or selected terminal equipment, etc. has the function of shutting down according to a pre-determined program, and can be implemented in a form with a normal and safe stop function control means and a means to confirm the stop signal.

[0351] An example of a joule heat detection device for detecting joule heat, which is arranged on each board, main line, cable, wiring, etc. of the DESCON emergency system, can be as follows.

[0352] For example, it detects abnormal temperature rises due to joule heat such as wire breaks and poor contacts in the power cables of refrigerators, washing machines, and electrical appliances in offices, houses, factories, etc.

[0353] For example, it detects abnormal temperature rises due to joule heat such as wire breaks and poor contacts in the power cables of movable control panels in factories, research institutes, data centers, servers, etc.

[0354] For example, detect abnormal temperature rise due to Joule heat such as disconnection or poor contact of the power cable of the conveyor in the logistics center.

[0355] For example, detect abnormal temperature rise due to Joule heat such as disconnection or poor contact of the power cable of the welder device at the construction site.

[0356] For example, detect abnormal temperature rise due to Joule heat such as disconnection or poor contact of the power cable of the cubicle in the building.

[0357] The DESCON emergency system can be configured, for example, as follows: the installed current value is energized, and each panel by system and the electrical equipment, electrical appliances, terminal equipment, etc. operate and stop as follows.

[0358] For the power supply from the substation and cubicle, for example, the main trunk of the CV cable connecting to the lighting and power panel is connected to the terminal block of the main breaker outside the panel with bolts and nuts and tightened with a predetermined tightening torque strength.

[0359] The KIV cable connected to the secondary terminal block of the main breaker with bolts and nuts and tightened with a predetermined tightening torque strength is connected to the primary terminal block of each branch breaker with bolts and nuts and tightened with a predetermined tightening torque strength.

[0360] From the secondary terminal block of each branch breaker, the KIV cable is connected to the terminal block of the distribution board or the wiring is branched via a magnetic switch and connected to the terminal block with bolts and nuts and tightened with a predetermined tightening torque strength.

[0361] From the terminal block of the distribution board to outside the panel, for example, it is connected to each load equipment with a CV cable.

[0362] The DESCON emergency system determines that when the current flowing through components such as electrical equipment reaches a preset temperature, for example, due to Joule heat generated by loosening, gaps, etc. in screws, bolts, terminal connectors, etc. of connection fittings on each panel, etc., the connection parts such as the corresponding terminals have generated Joule heat. This is done by, for example, attaching temperature sensors to each circuit such as CV cables and KIV cables, and inputting the detected temperatures of the wiring or copper bars, etc.

[0363] Monitor the CV cable alarm temperature with a wire or copper bar temperature detector connected to a temperature sensor installed on the CV cable at the connection part where the main power supply from the substation equipment and cubicle, for example, a trunk line such as a CV cable, is connected to the primary side terminal block of the main breaker of the lighting and power distribution panels with bolts and screws tightened to a predetermined tightening torque strength.

[0364] Monitor the CV cable alarm and temperature with a wire or copper bar temperature detector connected to a temperature sensor installed on the outside of the panel of the terminal block of the main breaker, for example, the CV cable, and inside the panel of the terminal block, for example, the KIV cable.

[0365] The DESCON emergency system applies to the following wires, for example, The maximum operating temperature of the core wire of IV - KIV is such that the allowable temperature of the insulator is 60 degrees. The maximum operating temperature of the core wire of VVF is such that the allowable temperature of the insulator is 60 degrees. The maximum operating temperature of the core wire of VCT is such that the allowable temperature of the insulator is 60 degrees. The maximum operating temperature of the indoor 600V core wire of HIV is such that the allowable temperature of the insulator is 75 degrees. The maximum operating temperature of the indoor 600V core wire of 600V CV is such that the allowable temperature of the insulator is 90 degrees. The maximum operating temperature of the MLFC core wire of MLFC is such that the allowable temperature of the insulator is 90 degrees.

[0366] The DESCON emergency system is pre-set arbitrarily for the maximum operating temperature of the IV-KIV core wire and the allowable temperature of the insulator at 60 degrees. For example, if it detects 55 degrees, which is -5 degrees from the maximum operating temperature of the core wire and the allowable temperature of the insulator at 60 degrees, it is regarded as the caution temperature, and relevant parties are alerted via a PC, tablet, smartphone, etc. with relevant information such as customer name, building name, facility name, location, type of lighting and power, and voice alerts. For example, if it detects 60 degrees as defined arbitrarily, it is regarded as the alarm temperature, the corresponding circuit is automatically cut off, and relevant parties are alerted via a PC, tablet, smartphone, etc. with relevant information such as customer name, building name, facility name, location, type of lighting and power, voice, numerical values, images, etc., and the breakers of the corresponding distribution board, sub-distribution board, control panel, main line, circuit, etc. of the equipment are automatically cut off. When the terminal equipment, electrical equipment, etc. such as program control and control of the corresponding terminal equipment shuts down according to a pre-determined program, the distribution board, sub-distribution board, control panel, main line, circuit, breaker, etc. are connected to a system-specific remote device, etc. via a cloud server, LAN, etc. through an emergency response protection program. The remote device of the corresponding distribution board, sub-distribution board, control panel, etc. can send a stop signal to the protection stop device to realize a safe and reliable stop function and a function to confirm the stop signal.

[0367] Also, for the above-mentioned maximum operating temperature of the core wire such as KIV, VVF, VCT, etc., and the allowable temperature of the insulator of 60 degrees, if it exceeds, for example, the arbitrarily set maximum operating temperature of the core wire and the allowable temperature of the insulator of 60 degrees, for example, the arbitrarily set 70 degrees, and 30 minutes have passed, it is determined to be dangerous due to Joule heat generation, and the corresponding circuit is automatically cut off. At the same time, an alert is sent to the relevant personnel via a PC, tablet, smartphone, etc., for example, with customer name, building name, facility name, location, type of lighting, power, voice, numerical value, image, etc. When the corresponding terminal equipment, electrical equipment, etc. are to be shut down by a program as predetermined by the program, the distribution board, sub-distribution board, control panel, main line, circuit, breaker, etc. are connected to a remote device by system type, etc., and via a cloud server, LAN, etc., by an emergency response protection program, the remote device of the corresponding distribution board, sub-distribution board, control panel, etc. sends a stop signal to the protection stop device to achieve a function of safely and surely stopping, and also a function of confirming the stop signal.

[0368] For the indoor 600V maximum operating temperature core wire of HIV and the allowable temperature of the insulator of 75 degrees, if it detects, for example, the arbitrarily set maximum operating temperature of the core wire and the allowable temperature of the insulator of 75 degrees, it is used as an alarm temperature, and an alert is sent to the relevant personnel via a PC, tablet, smartphone, etc., for example, with customer name, building name, facility name, location, voice, numerical value, image, etc.

[0369] For the maximum operating temperature of the core wire such as for HIV, the allowable temperature of the insulator is 75 degrees, which is arbitrarily set in advance. For example, if it exceeds the arbitrarily set maximum operating temperature of the core wire and the allowable temperature of the insulator, such as exceeding 75°C and reaching 76°C, it is regarded as the caution current, and an alert is sent to the relevant personnel by voice, numerical values, images, etc. on a PC, tablet, smartphone, etc. For example, the alert is sent with customer name, building name, facility name, location, type of lighting, power, voice, voice, numerical values, images, etc. Also, for example, if the arbitrarily set temperature of 76 degrees, etc. has elapsed for 30 minutes, etc., it is judged to be dangerous due to joule heat generation and the corresponding circuit is automatically cut off as the alarm temperature. At the same time, an alert is sent to the relevant personnel by a PC, tablet, smartphone, etc. with, for example, customer name, building name, facility name, location, type of lighting, power, voice, voice, numerical values, images, etc. When the terminal equipment such as the corresponding terminal equipment and electrical equipment is to be shut down by a program control, control, etc. determined in advance by a program, the distribution board, sub-distribution board, control panel, main line, circuit, breaker, etc. are connected to a remote device for each system, etc., and via a cloud server, LAN, etc., by an emergency response protection program, the remote device of the corresponding distribution board, sub-distribution board, control panel, etc. sends a stop signal to the protection stop device to realize the function of stopping safely and surely, and also to realize the function of confirming the stop signal.

[0370] For the CV indoor use, the maximum operating temperature of the core wire is 600V, and the allowable temperature of the insulator is 90 degrees. If, for example, the maximum operating temperature of the core wire and the allowable temperature of the insulator of 90 degrees are detected, or if 90 degrees set arbitrarily in advance has elapsed for 30 minutes, it is determined to be dangerous due to joule heat generation and set as the alarm temperature, and the corresponding circuit is automatically cut off. An alert is sent to the relevant personnel via PC, tablet, smartphone, etc. with voice, numerical values, images, etc. For example, the customer name, building name, facility name, location, type of lighting and power, voice, voice, numerical values, images, etc. are used to send the alert. When the program control, control, etc. of the corresponding terminal equipment, electrical equipment, etc. are to be shut down by a program determined in advance, the distribution board, sub-distribution board, control panel, main line, circuit, breaker, etc. are connected to a system-specific remote device, etc., and via a cloud server, LAN, etc., an emergency response protection program is used to enable the remote device of the corresponding distribution board, sub-distribution board, control panel, etc. to send a stop signal to the protection stop device to achieve a function of stopping safely and reliably. It can be an embodiment that realizes a function of confirming the stop signal.

[0371] The DESCON emergency system also sends alerts of voice, numerical values, and images to the PCs, tablets, and smartphones of the relevant personnel for notification, sends alerts of voice, numerical values, and images to the smartphones for notification, and the alert incoming sound rings until the relevant personnel confirm and reset it. Moreover, emails are continuously sent multiple times and the incoming sound continues to prevent the relevant personnel from missing the confirmation.

[0372] The DESCON emergency system pre-sets the maximum allowable temperatures, such as for KIV cables and CV cables, as well as the caution temperature and warning temperature, and sends real-time alerts in the form of voice, images, numerical values, etc. to the PCs, tablets, smartphones, etc. of relevant personnel. For breakers, etc. in switchboards, distribution boards, control panels, main lines, circuits, etc. of the corresponding equipment, automatic shutdown or, for example, for products, manufacturing, etc. by computer programs such as AI and IoT, and for commercial facilities where a large number of people gather, such as logistics centers, large refrigerators, refrigerators, terminal buildings, hotels, etc., for lighting, elevators, etc., for data centers for important data, research test results, etc., for substations of infrastructure, etc., and for various corresponding equipment such as trains and ships in transportation, electrical equipment, etc., when the terminal equipment, electrical equipment, etc. of the corresponding equipment is to be shut down according to a pre-determined program, the switchboard, distribution board, control panel, main line, circuit, breaker, etc. are configured by system-specific remote devices, etc., and the cloud server, LAN, etc. The system, which is composed of the above, realizes the normal and safe shutdown function and the function of being able to confirm the shutdown signal by implementing a function in which the remote device of the corresponding switchboard, distribution board, control panel, etc. transmits a signal to the protection stop device according to an emergency response protection program by the system-specific remote device, etc., and the cloud server, LAN, etc., and the selected terminal devices, etc. are shut down according to a pre-determined program.

[0373] Regarding the maximum allowable temperature, etc. for different types of electric wires, as well as the equations for caution temperature, warning temperature, and automatic shutdown. Regarding the relationship between the types of electric wires, their uses, the maximum allowable temperature, etc., caution temperature, warning temperature, and automatic shutdown.

[0374] The Joule heat program in the DESCON emergency system is, for example, based on the allowable temperatures of cables, wires, etc. for each temperature, such as the allowable temperature of IV·KIV being 60 degrees, VVF being 60 degrees, VCT being 60 degrees, HIV being 75 degrees, CV being 90 degrees, MLFC being 90 degrees, etc. It is arbitrarily determined in advance. For example, for the allowable temperature, for distribution boards, sub - distribution boards, junction boxes, connection devices, terminal devices, connected equipment, terminals, electrical equipment and appliances, cables, wires, etc., if they exceed the allowable temperature by +10 to 15 degrees, for example, after 15 minutes have passed, or if they exceed the allowable temperature by 15 degrees, it can be an embodiment where the alarm temperature can be judged. In this case, it can be an embodiment where the corresponding cables, circuits, connection devices, terminals, etc. are automatically cut off.

[0375] Also, it is a system that sends alerts to the PCs, tablets, smartphones, etc. of relevant personnel using, for example, customer names, building names, facility names, locations, types of lighting, power, voice, voice, numerical values, images, etc., to prevent oversight by continuously alerting the relevant personnel about the alarm temperature and the fact of automatic cutoff. The DESCON emergency system can be an embodiment that detects and judges the risk of, for example, Joule heat generation, where connection fittings, terminals, wires, circuits, etc. exceed the allowable temperature, and the covering material burns, melts, etc., causing the temperature of the corresponding wires, circuits, etc. to rise due to Joule heat, and the covering material of the electrical resistance of the corresponding cables, wires, circuits, etc. melts, resulting in phenomena such as spark, short - circuit, tracking, etc.

[0376] For reference, the conventional thermal conduction breaker has functions such as the over - current value A, etc., and the temperature of the corresponding circuit, the screws, bolts, terminals, etc. of the connection fittings rises with the passage of time, and the thermal conduction breaker with a protection function operates and cuts off at the set temperature, time, etc., to protect the corresponding circuit, connection fittings, etc. from electrical burnout, etc. with the function of preventing over - current.

[0377] An electronic breaker sets, in advance, a safety allowable current value A, for example, for conducting a corresponding circuit, etc., based on criteria such as the allowable current value standards of connection fittings such as the corresponding circuit, screws, bolts, terminals, etc. When the set current value A is reached, the thermal conduction breaker of the protection function operates and shuts off, protecting the corresponding circuit, connection fittings, etc. from electric burnout, etc. with the function of preventing overcurrent. The above thermal conduction breaker is the operation of the protection function of the corresponding breaker due to temperature rise, and the electronic breaker is also the operation of the protection function of the corresponding breaker when the allowable current value A is reached. There is currently no function in the prior art to instantaneously detect, for example, the spark tracking phenomenon that occurs instantaneously, such as when the insulation covering materials of the anode and cathode wires of the current cause the corresponding wire to short-circuit and tracking phenomenon at 1 sec / 12000 or 83 μsec, etc.

[0378] The DESCON emergency system uses a current transformer CT that detects current A in circuits, connection fittings, terminals, etc. of electrical equipment. It converts the current at, for example, 83 μsec obtained by dividing 1 second by 12000 times (which is a common multiple of power frequencies such as 50 HZ, 60 HZ, etc.) into voltage, and converts the real analog voltage with an analog-to-digital converter of the ADC. Then, with, for example, a microcomputer, etc., due to joule heat, etc. of connection fittings such as the corresponding panel circuit, screws, bolts, terminals, etc., cables, wires, terminal load equipment, etc., it detects a current that exceeds the allowable temperature of the insulation covering material of the anode and cathode wires of the electricity and melts, such as a current 15 to 90 times the normal current of the spark tracking phenomenon. By detecting the instantaneous current of the above 83 μsec, for example, using the normal current of 83 μsec, etc. as the denominator, and with a magnification of, for example, 15 times or more of the arbitrarily set normal current in advance, it sends an alert via the PC, smartphone, tablet, etc. of the relevant person, for example, with customer name, building name, facility name, location, type of lighting, power, voice, voice, numerical value, image, etc. It automatically shuts off the corresponding circuit, connection fittings, cables, wires, terminal load equipment, etc. at, for example, 20 times or more of the arbitrarily set normal current in advance, preventing serious electrical burnouts and electrical fires such as the insulation covering material of the wire melting at a high temperature due to joule heat, short-circuiting, sparking, and tracking phenomenon, etc. It has a great effect of preventing personal accidents both socially, economically, and domestically.

[0379] For the screws, terminals, etc. of connection hardware such as the above-mentioned distribution boards, sub-distribution boards, control panels, terminal load equipment, etc., looseness, gaps, etc. in circuits, etc., and the passage of heavy objects such as cables, electric wires, etc., for example, floor-embedded piping wiring, tensile force at connection parts, etc., the current-carrying area of the corresponding cable or wiring material becomes narrow. Since the current allows the current value to conduct constantly, if there is no conduction area for a predetermined circuit, cable, electric wire, etc., the thermal resistance increases in proportion to the current, and Joule heat is generated in proportion to the elapsed time. If the allowable temperature of each corresponding electric wire is exceeded, the insulation coating material of the anode and cathode of the electricity will melt and burn out, and the corresponding circuit and electric wire will short-circuit and spark. <Joule Heat Detection Device in DESCON Emergency System> One to n Joule heat detection devices are arbitrarily installed on temporary, movable, mobile power cables such as cubicles, distribution boards, sub-distribution boards, control panels, terminal outlets, refrigerators, freezers, conveyors, welders, movable control panels, PCs, servers, network devices, inspection operator devices, etc. in residential buildings, condominiums, offices, commercial facilities, hospitals, hotels, research institutes, exhibitions, exhibition halls, data centers, logistics centers, warehouses, factories, construction sites, etc.

[0380] Detect temperature rise due to disconnection, poor contact, etc. of the power cable. When an abnormal temperature is detected, automatically cut off the corresponding circuit.

[0381] Send alerts in real time to the PCs, tablets, smartphones, etc. of relevant personnel in the form of voice, images, numerical values, etc.

[0382] The system for detecting Joule heat in the DESCON emergency system installs temperature sensors for each circuit at connection fittings such as connection fittings for switchboards, circuits, etc., including nuts, bolts, terminal connectors, and connection parts of connection fittings. When the current value due to looseness, gaps, etc. in connection fittings such as those for switchboards, circuits, etc. is constant and the electrical conduction area decreases, electrical resistance heat is generated, and the electrical short-circuit heat due to the increase, etc. is detected. Temperature sensors are installed separately for each circuit at connection fittings, terminals, etc. of low-voltage electric lights, power distribution boards, main lines, electric lights, power distribution boards for power, electric lights, control panels for power, etc., and also near connection fittings, sockets, load equipment, etc. of each switchboard or main line, electric wire, terminal equipment, etc. Temperature sensors for each circuit are installed in distributors and remote switchboards. If the allowable temperature of each cable is exceeded and a predetermined caution temperature is reached, a caution signal is transmitted to alert the relevant personnel. It can be implemented such that when the caution temperature is set at a predetermined temperature and a set time has elapsed, or when an arbitrarily determined warning temperature is exceeded, the corresponding circuit is automatically shut off.

[0383] For high-voltage and low-voltage electric lights, power distribution boards for power, main lines, electric lights, power distribution boards for power, electric lights, control panels for power, electric lights, terminal equipment for power, electrical equipment and appliances, etc. of power receiving and transforming equipment, and control panels, remote switchboards, etc. of terminal equipment, electrical equipment, etc. (sometimes referred to as "switchboards" in this specification), for example, in the primary side wiring, the screws, bolts, terminal connectors of the connection fittings, and the wiring of the connection part of the connection fittings conduct the corresponding wiring when current is applied. The temperature of the wiring, etc. rises to a certain value due to expansion, and after a power outage, the wiring, etc. contracts due to a decrease in temperature. The phenomena such as expansion during power-on and contraction during power-off of the corresponding nuts, bolts, terminals, etc. of the connection fittings and the wiring are proportional to time and the number of years elapsed. The screws, bolts, terminals, etc. and the wiring of the connection part loosen, and gaps, etc. occur, resulting in poor connection of the wiring and connection fittings, etc., and current conducts through electrical materials and connection devices, etc. For example, when the conduction area decreases to a predetermined size, etc., the current value is constant, so the contact conduction area decreases, the temperature of the thermal resistance value increases, Joule heat is generated, the temperature rises, the connection fittings, wiring, etc. become high-temperature, exceeding the allowable temperature of the insulation coating materials of each cable, wiring, etc., and burnout may occur, and an electrical fire accident may occur.

[0384] The maximum allowable temperature for different types of cables, electric wires, etc. can be arbitrarily set in advance for temperatures such as caution temperature and alarm temperature alerts for Joule heat, automatic shutdown, etc.

[0385] The DESCON emergency system attaches, for example, '1 to N' 'temperature sensors' to 'each cable' for the inside of the panel, such as 'KIV cable maximum allowable temperature 60 degrees', and outside the panel, such as 'CV cable maximum allowable temperature 90 degrees'. For example, for the KIV cable set arbitrarily in advance, due to the Joule heat generated by the reduction of the current conduction area of the wiring connection failure caused by the looseness, gaps, etc. of the above-mentioned screws, bolts, terminals, etc., the temperature of the corresponding cable rises, and before the insulating coating material burns out. For example, the KIV cable set arbitrarily in advance has a maximum allowable temperature of 60 degrees, or the'safety allowable temperature 60 degrees' of the corresponding cable set arbitrarily in advance is used as the 'attention temperature' for alert transmission. The 'alarm temperature' is, for example, '65 degrees' of 'the maximum allowable temperature + 5 degrees' set arbitrarily in advance. If it exceeds 65°C and reaches 66°C, it is regarded as the 'attention current', and an alert is sent to the relevant personnel by voice, numerical value, image, etc. on a PC, tablet, smartphone, etc., for example, customer name, building name, facility name, location, type of lighting, power, voice, voice, numerical value, image, etc. Also, if the temperature such as '65 degrees' continues for '1 minute or more', and if it rises above '65 degrees', the corresponding circuit is 'automatically shut off' as the 'alarm temperature', and the relevant customer name, building name, facility name, location, type of lighting, power, capacity, electrical equipment at the system terminal, load equipment name, etc. are alerted and notified to the relevant personnel's PC, tablet, smartphone, etc. by voice, numerical value, image, etc. Also, the alert incoming sound rings until the relevant personnel confirm and reset it to prevent the relevant personnel from overlooking the confirmation.

[0386] The summary of the DESCON emergency system is that for cables such as KIV cables and CV cables, the maximum allowable temperature is set in advance as the attention temperature and warning temperature, and real-time alerts are sent to the PCs, tablets, smartphones, etc. of relevant personnel in the form of voice, images, numerical values, etc. For breakers, etc. in switchboards, distribution boards, control panels, main lines, circuits, etc. of the corresponding equipment, they are automatically shut off, or for products, manufacturing, etc. by computer programs such as AI and IoT, and for logistics centers, large refrigerators, refrigerators, etc. where a large number of people gather, commercial facilities, terminal buildings, hotels, etc., for lighting, elevators, etc., for data centers for important data, research test results, etc., for substations of infrastructure, etc., and for various corresponding equipment such as trains and ships in transportation, electrical equipment, etc., when the corresponding terminal equipment, electrical equipment, etc. need to be shut down according to a pre-determined program, the system composed of remote devices by system, cloud servers, LAN, etc. is configured by an emergency response protection program by remote devices of the corresponding switchboards, distribution boards, control panels, etc. to send signals to the protection stop device, and the control, etc. of all or selected terminal devices, etc. can have the function of shutting down according to a pre-determined program. It can be an embodiment with a function of stopping normally and safely and having a function of confirming the stop signal.

[0387] It is the maximum allowable temperature joule heat program and the maximum allowable temperature and time combined joule heat program attention temperature, warning temperature, and automatic shut-off equation for different types of wires set arbitrarily in advance.

[0388] The rated current program in the DESCON emergency system uses an ammeter CT that detects current A in the circuits, connection fittings, terminals, etc. of electrical equipment. It converts the current at, for example, 83 μsec obtained by dividing 1 second by 12,000 times (which is a common multiple of power frequencies such as 50 Hz and 60 Hz) into voltage to obtain a real analog voltage. This voltage is used in the ADC main line, electric lights, distribution boards for power equipment, junction boxes, branch main lines, control panels, distributors, wiring, each terminal equipment, electrical appliances, instruments, etc. in the head office, factory, R & D institute, store, data center, logistics center, warehouse, large exhibition hall, hotel, terminal building, etc. of the relevant enterprises. For example, in a factory or R & D institute where products are manufactured or researched, it is related to the types, processes, quantities, loads, and construction methods of products or goods, etc. Also, in stores, data centers, logistics centers, warehouses, large exhibition halls, hotels, terminal buildings, etc., it is related to various businesses such as events, products, items, banquet halls, tenants, etc. according to weekly, monthly, seasonal, end-of-year, and beginning-of-year periods. Additionally, it is related to means of transportation such as trains, cars, ships, airplanes, etc. and electrical equipment such as solar power, wind power, ocean currents, etc. for regenerative power. The current values of the distribution boards, main lines, electric lights, distribution boards, circuits, breakers, junction boxes, branch main line control panels, distributors, wiring, each terminal equipment, electrical appliances, instruments, etc. are detected in real time by the ammeter CT installed in each board. According to the wiring size, etc., for the allowable current value of the current value, for example, depending on the building use, etc. and the production or operation of products, etc. and the operating status of load equipment, electrical appliances, etc., the current value passing through the wiring, connection fittings, etc. is detected. The safety protection operating time of the breaker for each current value determined by size, such as for the main line, wiring, circuit, terminal, etc., for example, for a rated current value of 30 A, the operating time of the protection interruption of the corresponding breaker with a current value of 1.25 times the rated current value, i.e., 37.5 A, can be 60 minutes or less.

[0389] When the detection current value of the 30A breaker in the DESCON emergency system detects, for example, 31A, the operating time of the corresponding breaker will be within 73 minutes. If the preset operating time is set arbitrarily, for example, to an alert coefficient of 0.7, the alert operating time = (73 minutes × the arbitrarily preset alert coefficient 0.7) = 51.10 minutes, and the automatic shutdown operating time for a current of 31A = (73 minutes × 0.9) = 65.7 minutes for automatic shutdown. For example, the upper limit allowable current of the rated current 30A is 2.0 times the rated current. When it is 30A × 2.0 times = 60A, the breaker operating time is 2.0 minutes. If the DESCON emergency system detects an overcurrent of 60A, for example, the arbitrarily determined alert coefficient 0.7 = 2 minutes × 0.7 = the alert time after detection is 1.4 minutes, and it will send alerts to the PCs, smartphones, tablets, etc. of the relevant personnel, for example, with customer name, building name, facility name, location, type of lighting, power, voice, voice, numerical values, images, etc. The arbitrarily preset automatic shutdown coefficient is, for example, 2 minutes × 0.9 = 1.8 minutes, and it can be an embodiment that determines the alert arbitrary shutdown time of 1.8 minutes.

[0390] In addition, the DESCON emergency system is a system that continuously sends alerts to the PCs, smartphones, tablets, etc. of the relevant personnel, alerting them that the breakers and load equipment in the switchboard, distribution board, control panel, main line, circuit, etc. have been automatically shut down, and continues to send alerts until the relevant personnel confirm and reset the alert transmission.

[0391] The DESCON emergency system can achieve a safe and trouble-free automatic shutdown function for relevant equipment, etc. by shutting down according to a pre-determined program for system facilities such as electrical equipment that can operate without automatic shutdown, electrical equipment that automatically shuts down, and for products, manufacturing, etc. by computer programs such as AI and IoT, logistics centers, large refrigerators, commercial facilities where many people gather such as refrigerators, terminal buildings, hotels, etc., lighting, elevators, etc., data centers for important data, research test results, etc., substations of infrastructure, relevant important various equipment such as trains and ships in transportation, and electrical equipment that is not subject to automatic shutdown. The system is composed of remote devices for each system such as distribution boards, sub-distribution boards, control panels, main lines, circuits, breakers, etc., cloud servers, LAN, etc. Through an emergency response protection program for each system, the remote devices of relevant distribution boards, sub-distribution boards, control panels, etc. transmit signals to the protection stop device, and have the function of shutting down normal and safe stop function control means and collectively or selected terminal devices, etc. according to a pre-determined program, and can be in an embodiment with a function of normally and safely controlling the stop function and a function of confirming the stop signal.

[0392] The DESCON emergency system creates a database of the relationship between rated current, current value, and operating time for the safety protection of electrical equipment. It detects whether the conduction current value of the breaker installed on the panel exceeds the rated allowable current value, and determines whether it is appropriate below the rated allowable current value. If it exceeds the rated allowable current value, it determines how many minutes within which the breaker of the corresponding circuit should be tripped based on the number of amperes of the excess current value A. If it exceeds, it sends an alert, such as customer name, building name, facility name, location, type of lighting, type of power, voice, voice, to the relevant person's PC, tablet, smartphone, etc. The distribution board, sub-distribution board, control panel, main circuit, etc. of the corresponding equipment and remote devices of each system, through the emergency response protection program via a cloud server, LAN, etc., can be implemented such that the remote device of the corresponding distribution board, sub-distribution board, control panel, etc. sends a stop signal to the protection stop device to stop safely and reliably, and a function to confirm the stop signal can also be implemented.

[0393] For the DESCON emergency system, for overcurrent with respect to the rated current of each wire, the allowable current is 1.25 times the rated current. The breaker operating time for an allowable current 1.25 times the overcurrent is 60 minutes or less. It calculates an arbitrarily determined alert transmission coefficient in advance with the detected overcurrent current and an arbitrary time, and sends an alert, such as customer name, building name, facility name, location, type of lighting, type of power, voice, voice, to the relevant person's PC, smartphone, tablet, etc. It can be implemented such that the corresponding wire is automatically tripped with an arbitrarily determined automatic tripping coefficient set in advance.

[0394] Regarding the rated current value, for example, 30A, the relationship between the operating time when the rated allowable current value is 1.25 times or exceeds 31A, an arbitrarily determined rated current value in advance is as follows.

[0395] In the DESCON emergency system, for the overcurrent with respect to the rated current of each electric wire, the allowable current is 1.25 times the rated current, and the operating time of the protective breaker is, for example, 60 minutes for 30 A or less, and the breaker operating time for the allowable current of 2.0 times the overcurrent is 6 minutes or less. The alert transmission coefficient, which is arbitrarily determined in advance by the detected current that has detected the overcurrent, calculates the operating time and sends an alert to the PCs, smartphones, tablets, etc. of the relevant personnel, for example, by customer name, building name, facility name, location, type of lighting, power, voice, voice, etc. It can be configured to automatically shut off the corresponding electric wire at the detected current of the automatic shut-off coefficient arbitrarily determined in advance.

[0396] For electrical equipment, such as distribution boards, main lines, branch board connection fittings, circuits, terminals, etc., and branch main lines, junction boxes, branch main lines, control panels, wiring, terminal load equipment, electrical appliances, wiring, terminal appliances, etc., in the head offices, factories, R & D institutes, stores, data centers, logistics centers, warehouses, large exhibition halls, hotels, terminal buildings, etc. of enterprises, etc., for the production and research of products or goods, etc., including types, processes, quantity loads, construction methods, etc., and also for handling in stores, data centers, logistics centers, warehouses, large exhibition halls, hotels, terminal buildings, etc., such as events, goods, articles, banquet halls, tenants, etc., on a weekly, monthly, seasonal, end-of-year, beginning-of-year basis, etc. During peak hours, the operation of the corresponding equipment is highly loaded. For distribution boards, main and branch lines, branch boards, control panels, terminal load equipment, electrical appliances, terminal appliances, etc., for example, the rated current of wires from 30A to 2000A is used in combination with the corresponding terminal load equipment, electrical appliance equipment, terminal load appliances, etc. For load equipment that exceeds the rated current capacity of each wire, such as the branch main line of the construction site distribution board for construction work, the power drum of each wiring, etc., and for terminal machinery equipment, electrical appliance equipment, power tools, etc., the current per unit is below the specified rated current. However, when the electrical capacity or quantity per unit of terminal load machinery equipment, electrical appliance equipment, power tools, etc. is below the rated current of the connection fittings, terminals, wiring circuits, main lines, wiring, etc. of the corresponding board, overcurrent does not occur. On the other hand, for example, when the electrical capacity or number of terminal load machinery equipment, electrical appliance equipment, power tools, etc. connected to the corresponding board, power drum, etc. exceeds due to the usage situation, or when the operating rate of the system equipment exceeds, the current, which is the power consumption of the electrical equipment, may generate an overcurrent above the rated current in the corresponding system board, main line, circuit, etc.

[0397] Thermal circuit breakers installed on each panel, etc. will cut off the corresponding circuit after a certain period of time. However, if the current in the corresponding circuit exceeds the rated current, for example, due to overcurrent such as in temporary and permanent power supplies at construction sites, resulting in electrical burnout and fires, or in logistics centers, warehouses, etc., when the corresponding breaker, main line, circuit, wire, connection fittings, etc. on the panel are used simultaneously and in multiple numbers, exceeding the rated current capacity, or when the current capacity exceeds the diameter and conduction area of a given wire, etc., the electrical thermal resistance increases, the temperature of the corresponding wire, main line, cable, connection fittings, etc. rises, and Joule heat is generated. For example, the electrical insulation coating material melts, the connection fittings become hot, etc. There are cases where electrical burnout and fire accidents occur due to overcurrent caused by an increase in the number of terminal load equipment and electrical equipment, the consumption of electrical capacity, or the use of a large number above a certain level.

[0398] When the DESCON emergency system detects a conduction current value of 31A in a 30A breaker, for example, the operating time of the corresponding breaker will be within 73 minutes. If the previously arbitrarily set operating time is set to an alert coefficient of 0.7, for example, the alert operating time = (73 minutes × the previously arbitrarily determined alert coefficient of 0.7) = 51.10 minutes, and an alert can be sent to the PCs, smartphones, tablets, etc. of relevant personnel as a warning overcurrent. Also, an automatic shutdown operating time of 31A current = (73 minutes × the previously arbitrarily determined alert coefficient of 0.9) = 65.7 minutes can be set for automatic shutdown. Also, for example, when the upper limit allowable current of a 30A rated current is 2.0 times the rated current, i.e., 30A × 2.0 = 60A, the breaker operating time is 2.0 minutes. If an overcurrent of 60A is detected as described above, with an arbitrarily determined alert overcurrent alert coefficient of 0.7, the alert time after detection = 2 minutes × 0.7 = 1.4 minutes, and an alert can be sent to the PCs, smartphones, tablets, etc. of relevant personnel. Also, with a previously arbitrarily determined alert shutdown coefficient, for example, a shutdown coefficient of 0.9 for 2 minutes × 0.9 = 1.8 minutes, an automatic shutdown can be implemented with an alert arbitrary shutdown time of 1.8 minutes.

[0399] The DESCON emergency system can be configured to send alerts to the PCs, smartphones, tablets, etc. of relevant personnel, and continuously send, for example, customer name, building name, facility name, location, type of lighting, type of power, voice, and voice alerts until the relevant personnel confirm and reset the alert transmission, while automatically shutting off breakers and load equipment in switchboards, distribution boards, control panels, main lines, circuits, etc.

[0400] For system facilities and electrical equipment that can function properly even after automatic shutdown, such as electrical equipment, the DESCON emergency system automatically shuts them down. For example, for products, manufacturing, etc. by computer programs such as AI and IoT, and for logistics centers, large refrigerators, refrigerators, etc., as well as for lighting, elevators, etc. in commercial facilities, terminal buildings, hotels, etc. where many people gather, for data centers for important data, research test results, etc., for substations of infrastructure, etc., and for various corresponding facilities such as trains and ships in transportation, for the corresponding terminal equipment of electrical equipment, etc., when the terminal equipment such as electrical equipment shuts down according to a pre-determined program, the system composed of remote devices for each system, cloud servers, LAN, etc. in switchboards, distribution boards, control panels, main lines, circuits, breakers, etc. is configured with an emergency response protection program by remote devices for the corresponding switchboards, distribution boards, control panels, etc. to send signals to the protection stop device to achieve the function of stopping safely and normally. In another embodiment, a batch or selected terminal equipment, etc. is configured with the function of shutting down according to a pre-determined program, with the function of stopping safely and normally, and also with the function of confirming the stop signal.

[0401] The DESCON emergency system creates a database of the relationship between current values and operating times for the safety protection of electrical equipment, and detects and inputs whether the conduction current value of the breaker installed on the panel is below or exceeds the rated allowable current value such as JIS. It can be configured to determine whether it is appropriate below the rated allowable current value, and if it exceeds the rated allowable current value, it can determine within how many minutes the breaker of the corresponding circuit should be tripped based on the number of amperes of the excessive current value. Also, when tripping, alerts such as customer name, building name, facility name, location, type of lighting and power, voice, etc. are sent to the PCs, tablets, smartphones, etc. of relevant personnel, and alerts are sent in real time with voice, images, numerical values, etc. The automatic tripping is carried out by an emergency response protection program via a remote device of the relevant distribution board, sub-distribution board, control panel, etc., a cloud server, a LAN, etc. The remote device can be configured to send a stop signal to the protection stop device to ensure a safe and reliable stop function and also to have a function to confirm the stop signal.

[0402] When the current in the DESCON emergency system exceeds the rated current value of each breaker due to overcurrent, the conduction area of each wire is determined. When a current exceeding the predetermined rated current flows, the thermal resistance of the electricity increases due to an overcurrent of 100% or more with respect to the conduction area, generating Joule heat of the electricity. For example, the allowable temperatures of IV·KIV, VVF, VCT, HIV, CV, MLFC, etc. of each wire are 60 degrees, 60 degrees, 60 degrees, 75 degrees, 90 degrees, 90 degrees, etc. When the temperature of cables, wires, etc. for each wire exceeds and the current value flowing through is, for example, below the current value at which the breaker thermally operates or does not reach the operating current value of an electronic breaker or the like, the breaker does not operate and trip, generating Joule heat, etc., exceeding the allowable temperature of the wire, melting the insulating coating material of the wire, causing burning and fire of the wire, etc. in the corresponding, for example, inside the terminal block of the distribution board. For example, the maximum allowable temperature of the CV cable is 90 degrees. When the power is turned on, the detected temperatures, for example, 33.2 degrees for phase R, 33.3 degrees for phase S, and 32.9 degrees for phase T are detected and stored in the database. In advance, for example, the maximum allowable temperature of 90 degrees is set as the caution temperature, and the alarm temperature is set arbitrarily in advance, for example, as 95 degrees, which is the maximum allowable temperature + 5 degrees. Or, if the temperature of 95 degrees continues for 1 minute or more and rises above 95 degrees, it is set as the alarm temperature, automatically shutting off the corresponding circuit, and alerting, for example, customer name, building name, facility name, location, type of lighting, power, voice, voice, etc., numerical values, images, etc. to the PCs, tablets, and smartphones of the relevant personnel. Also, the alert incoming sound continues until the relevant personnel confirm and reset it, preventing the relevant personnel from overlooking the confirmation. This can be an embodiment.

[0403] The DESCON emergency system, due to overcurrent, for example, based on the allowable temperatures of cables, wires, etc. for each temperature such as the allowable temperature of IV·KIV being 60 degrees, VVF being 60 degrees, VCT being 60 degrees, HIV being 75 degrees, CV being 90 degrees, MLFC being 90 degrees, etc., can be in an embodiment where, arbitrarily determined in advance, for example, when the allowable temperature is exceeded, for example, by any +10 to 15 degrees and any 5 minutes have elapsed, or when the allowable temperature is exceeded by 15 degrees, it is determined as the alarm temperature. In this case, it can be in an embodiment where the corresponding cables, circuits, connection devices, terminals, etc. are automatically cut off. Also, to the PCs, tablets, smartphones of the relevant persons, for example, customer name, building name, facility name, location, lighting, type of power, voice, voice, etc. voice, numerical values, images, etc. are sent as an alert with the alarm temperature and the fact that automatic cutoff has occurred, and the alert incoming sound continuously sends emails until the relevant person checks and resets, and the incoming sound continues, and it can be in an embodiment to prevent the relevant person from overlooking the check.

[0404] The DESCON emergency system, for example, when joule heat is generated and exceeds the allowable temperatures of connection fittings, terminals, wires, circuits, etc., and the covering material burns out, melts, etc., causing the corresponding wires, circuits, etc. to short-circuit, and when the temperature of the corresponding wires, etc. rises due to joule heat and reaches an arbitrarily determined temperature in advance before the insulating covering material melts, which is higher than the allowable temperature of each wire arbitrarily determined in advance, to the PCs, smartphones, tablets, etc. of the relevant persons, for example, customer name, building name, facility name, location, lighting, type of power, voice, voice, etc. voice, numerical values, images, etc. are sent as an alert, and further, if it rises to an arbitrarily determined temperature in advance, it is automatically cut off, and it can be in an embodiment to detect and judge the occurrence of a spark tracking phenomenon due to the melting and burning of the covering material of the electrical resistance of the corresponding cables, wires, circuits, etc. caused by joule heat.

[0405] The rise in temperature of the corresponding connection fittings, terminals, circuits, electric wires, etc. exceeds the allowable temperature defined for each wire type, and the insulating coating material that prevents short circuits, sparks, etc. in the electric wires melts due to the increase in temperature of the corresponding Joule heat, and a spark tracking phenomenon occurs at the corresponding melted location, which becomes a cause of electrical fire accidents rather than electrical burnout.

[0406] Conventional thermal conduction breakers operate based on overcurrent values A, etc. and the elapsed time, causing the temperature of the corresponding circuit, screws, bolts, terminals, etc. of the connection fittings to rise, and the thermal conduction breaker with a protection function operates and shuts off at the set temperature, time, etc., protecting the corresponding circuit, connection fittings, etc. from electrical burnout and other problems with an overcurrent prevention function.

[0407] An electronic breaker sets, for example, a safety allowable current value A that conducts the corresponding circuit, etc. based on criteria such as the allowable current value of the connection fittings of the corresponding circuit, screws, bolts, terminals, etc. in advance. When the set current value A is reached, the breaker with a protection function operates and shuts off, protecting the corresponding circuit, connection fittings, etc. from electrical burnout and other problems with an overcurrent prevention function. The operation of the protection function of the thermal conduction breaker is due to the rise in temperature, and the operation of the protection function of the electronic breaker is also due to reaching the allowable current value A.

[0408] The DESCON emergency system includes an ammeter CT that detects current in circuits, connection fittings, terminals, etc. of electrical equipment due to overcurrent, etc., and can convert current into voltage at frequencies corresponding to each frequency of the power supply, such as 50 Hz, 60 Hz, etc., for example, 83 μsec 12,000 times per second, etc., to obtain a real analog voltage. The analog-to-digital converter of the ADC converts this voltage, and, for example, a microcomputer, etc., detects the current in the relevant panel circuits, connection fittings such as screws, bolts, terminals, cables, wires, terminal load equipment, etc., and when the current is below the allowable current, such as when the electrical heat resistance heat such as Joule heat does not cause the operation of thermal operation, electronic circuit breakers, etc., and does not cause deterioration or melting of the wire coating material, etc., for example, at 83 μsec, it can detect a current that is, for example, 15 to 80 times the normal current, or detect the allowable temperature of the relevant circuit wire, and send alerts to the PCs, smartphones, tablets, etc. of relevant personnel, for example, customer name, building name, facility name, location, type of lighting, power, voice, numerical values, images, etc. It can automatically cut off the relevant circuit, connection fittings, cables, wires, control IOTB, terminal load equipment, etc., for example, with a multiple of 20 times or more using the previously arbitrarily determined normal current as the denominator. For example, at high temperatures of Joule heat, the insulation coating material of the wire melts, causing short circuits, sparking, tracking phenomena, etc., to prevent serious electrical burns and electrical fires, and has a great effect of preventing personal accidents both socially, economically, and domestically. As described above, the embodiments of the present invention have been explained, but the present invention is not limited to the above-described embodiments and can be variously modified within the technical scope grasped from the description of the claims.
