[0124] The digital emergency electrical safety control system of the present invention, namely the DESCON emergency system, comprises: a power device, an instantaneous current value detection device, an instantaneous current value determination device, a first alarm notification information output unit, an automatic power supply cut-off determination unit, a first power supply cut-off device, a second power supply cut-off device, a chassis internal temperature information acquisition unit, a circuit temperature information acquisition unit, a chassis internal temperature monitoring unit, a circuit temperature information monitoring unit, a second alarm notification information output unit, and a third alarm notification information output unit.

[0125] In this specification and accompanying drawings, the “Digital Emergency Electrical Safety Control System” will sometimes be referred to as the “DESCON Emergency System” or “DESCON”.

[0126] In an electrical installation, a circuit originating from the power source (power-side circuit) and multiple circuits branching from the power-side circuit and extending toward multiple loads (load-side circuits) are electrically connected within a chassis. A first electrical device is installed in the power-side circuit within the chassis, and second electrical devices are installed in the multiple load-side circuits within the chassis. Both the first electrical device installed in the power-side circuit and the multiple second electrical devices installed in the multiple load-side circuits are housed within the chassis.

[0127] Such electrical devices include junction boxes for connecting various power distribution facilities, distribution panels, sub-distribution panels, lighting panels, power panels, control panels, remote control device panels, distribution panels or sub-distribution panels, etc., to equipment / machinery via extension lines or branch wiring connections.

[0128] As a first electrical device, it is installed in the chassis constituting the above-mentioned power device to realize the electrical connection between the power supply side circuit leading out from the power supply side and the load side circuit extending toward the load. Examples include main circuit breakers and residual current circuit breakers.

[0129] As a secondary electrical device, it is a different type of circuit switch from the main circuit breaker and residual current circuit breaker mentioned above. Examples include magnetic switches, power relays, and solid-state relays.

[0130] The load to which the load-side circuit is directed includes, for example, power / electrical installations and equipment that receive power and operate, such as prime movers, elevators, air conditioning systems, ventilation systems, lighting systems, refrigerators / freezers, measuring instruments, computer equipment, surveillance cameras, medical equipment, and communication devices. This includes power / electrical installations and equipment that can be installed and used both inside and outside buildings, power / electrical installations / communication devices / equipment installed in transportation agencies / mobile devices such as electric trains, vehicles, airplanes, and ships, as well as sockets that connect to them.

[0131] These loads are connected to the head end of each of the multiple load-side circuits.

[0132] The instantaneous current detection device is connected to the above-described circuit to detect the instantaneous current value flowing through the circuit in an instant, i.e., the instantaneous AC current value or the instantaneous DC current value. For example, it is connected to the above-described load-side circuit to detect the instantaneous current value flowing through the load-side circuit in an instant, i.e., the instantaneous AC current value or the instantaneous DC current value.

[0133] As a device for detecting instantaneous current values, a current sensor using an instrument current converter (CT) can be used, or... Figure 17 The DC instantaneous current measuring instrument with Hall element shown.

[0134] The instantaneous time unit for instantaneous detection is, for example, 1 / 12000 of a second = 83 microseconds, and can be arbitrarily set between 1 / 50000 (=20 μsec) and 1 / 100000 of a second (=10 μsec). Alternatively, it can be set to a microsecond within this range that is proportional to the performance of the computer (PC) constituting the DESCON emergency system.

[0135] The instantaneous time unit for instantaneous detection is set to microseconds between 1 / 50000 (=20μsec) and 1 / 100000 (=10μsec). This facilitates faster detection of the danger of tracking phenomena and allows for necessary responses such as power cut-off before tracking phenomena occur.

[0136] The instantaneous current value determination device compares the detected instantaneous current value with a preset allowable current value range.

[0137] For example, an instantaneous current value in a circuit that is detected to be 12 to 17 times the normal current value is determined to be within the range of alarm issuance described later.

[0138] Additionally, for example, an instantaneous current value in a circuit that is detected to be 17 to 22 times the normal current value is determined to be within the range of power cut-off and alarm activation as described later.

[0139] When the instantaneous current value determination device determines that the instantaneous current value is within the predetermined alarm issuance range, the first alarm notification information output unit outputs alarm notification information to the administrator terminal used by the administrator managing the power device and the responsible person terminal held by the person in charge of the management of the power device, along with processing to determine the information of the power device involved in the chassis.

[0140] The administrator terminal can be a personal computer equipped with an image information display unit such as a monitor. The person in charge terminal can be a portable terminal such as a smartphone with the application for using the system of this invention downloaded on it.

[0141] The administrator terminal and the person in charge terminal are connected to the computer system, which is composed of the server computer and other components of the digital emergency electrical safety control system, namely the DESCON emergency system, of the present invention, via communication networks such as the Internet and dedicated lines, in a manner that enables mutual information communication.

[0142] When the instantaneous current value determination device determines that the instantaneous current value is within a predetermined power supply cutoff range, the automatic power supply cutoff determination unit can determine whether the load supplied with the current of the instantaneous current value determined by the device is a load for which power supply can be automatically cut off.

[0143] The first power supply disconnection device automatically disconnects the power supply to the load that is determined by the power supply disconnection determination unit to be automatically disconnectable.

[0144] When the power supply can be automatically cut off, the second power supply cutting device cuts off the power supply to the load device control device that controls the load that is determined to be unable to be automatically cut off, and then performs the process of automatically cutting off the power supply to the load.

[0145] The chassis internal temperature information acquisition unit performs the following processing: continuously detects the temperature inside the chassis, and outputs information related to the detected temperature inside the chassis as digital information, that is, the chassis internal temperature information together with information on the power device involved in the chassis.

[0146] The circuit temperature information acquisition unit, which consists of digital temperature sensors and digital thermometers, performs the following processing: continuously detects the temperature of the circuit and outputs digital information related to the detected temperature of the circuit, namely, circuit temperature information, along with information about the circuit whose temperature is determined.

[0147] The chassis internal temperature monitoring unit compares the temperature inside the chassis obtained by the chassis internal temperature information acquisition unit with the preset chassis internal monitoring temperature.

[0148] The circuit temperature monitoring unit compares the temperature of the circuit obtained by the circuit temperature information acquisition unit with a preset circuit monitoring temperature.

[0149] The second alarm notification information output unit performs the following processing: when the chassis temperature monitoring unit determines that the temperature inside the chassis obtained by the chassis temperature information acquisition unit exceeds the monitored temperature inside the chassis, it outputs alarm notification information to the administrator terminal and the responsible person terminal, along with information on the power device involved in the chassis.

[0150] The third alarm notification information output unit performs the following processing: when the load-side circuit temperature monitoring unit determines that the temperature of the circuit obtained by the circuit temperature information acquisition unit exceeds the circuit monitoring temperature, it outputs alarm notification information along with information identifying the circuit that has been determined to be the circuit to the administrator terminal and the responsible person terminal.

[0151] The digital emergency electrical safety control system of the present invention, namely the DESCON emergency system, is constructed by a computer system consisting of a server computer or the like. Although not shown in the figure, the computer system is composed of a computer with the following structure: it includes a CPU, ROM, RAM, hard disk, communication interface, and other information input / output units as storage units, which are connected by necessary buses. The CPU controls the system according to the operating system and pre-installed or downloaded computer programs to realize various functions of the system in this embodiment. The ROM stores the operating system and various computer programs, and also stores the data required by the CPU to perform processing for each control. The RAM stores the data required by the CPU to perform processing, and is also used as a work area for the CPU to rewrite information as needed.

[0152] The processing work performed by the aforementioned instantaneous current value determination device, first alarm notification information output unit, automatic power supply cut-off determination unit, first power supply cut-off device, second power supply cut-off device, chassis internal temperature monitoring unit, circuit temperature information monitoring unit, second alarm notification information output unit, and third alarm notification information output unit is executed by such a computer system.

[0153] The aforementioned instantaneous current value determination device, first alarm notification information output unit, automatic power supply cut-off determination unit, first power supply cut-off device, second power supply cut-off device, chassis internal temperature monitoring unit, circuit temperature information monitoring unit, second alarm notification information output unit, and third alarm notification information output unit do not need to be equipped in a single device / equipment.

[0154] For example, the following approach can also be adopted: the power installation is equipped with a device / equipment having part of its structure, which is connected via a wired or wireless network to other devices / equipment consisting of a computer with a different structure located separately from the power installation in a manner that enables information communication.

[0155] Alternatively, the following method can also be adopted: In the power device, a device / equipment with some of the above structures is equipped. It is connected via a wired or wireless network in a manner that enables information communication to other device / equipment composed of a computer with a part of another structure located at a position separated from the power device and other device / equipment composed of a computer with the remaining part of another structure.

[0156] Regarding the above structure, the following structure can also be adopted: Among one or more other device / equipment that are equipped at a position separated from the power device, connected via a wired or wireless network, and have a part or the remaining structure of the above another structure, there is a server computer set on the cloud.

[0157] <An example of the tracking detection system in the DESCON emergency system>

[0158] The above DESCON emergency system can adopt the structure of the tracking detection system described below.

[0159] In this tracking detection system, as Figure 16 shown, 1) Convert the analog instantaneous AC current value detected by the current detection CT into an analog voltage value; 2) Convert the analog voltage value into a digital voltage value; 3) Convert the digital voltage value into a current value to detect abnormal currents such as sparks and tracking.

[0160] In this series of processing operations, for example, a structure implemented by a microcontroller or microprocessor in the form of a printed circuit board can be adopted.

[0161] In this tracking detection system, for example, the following method can be adopted: Measure the current with a frequency of 50Hz at 1 / 20000 seconds and the current with a frequency of 60Hz at 1 / 16666 seconds, measure the short - circuit currents such as the instantaneous sparks and tracking phenomena generated, and detect the large currents of sparks and tracking.

[0162] The following method can also be adopted: Detect the instantaneous current in units of 1 / 20000 seconds for 50Hz and 1 / 16666 seconds for 60Hz, convert the detected analog current value into an analog voltage value, and then convert the converted analog voltage value into a digital voltage value and further convert it into a current value to detect abnormal currents such as sparks and tracking.

[0163] This kind of tracking detection system can be called the DESCON tracking detection digital system. The above DESCON tracking detection digital system is a tracking detection system in a circuit through which an alternating current flows.

[0164] <Another example of the tracking detection system in the DESCON emergency system>

[0165] The above-mentioned DESCON emergency system can adopt the structure of another tracking detection system with the following description.

[0166] In this tracking detection system, as Figure 17 shown, 1) the analog instantaneous DC current value detected by the DC instantaneous current meter 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.

[0167] As the DC instantaneous current meter, as Figure 17 shown, in addition to the Hall element detector and the fluxgate detector, a DC instantaneous current meter well-known in the technical field can also be adopted.

[0168] In the process of converting the analog voltage value into a digital voltage value, for example, a structure implemented by a microcontroller or a microprocessor in the form of a printed circuit board can be adopted.

[0169] In this tracking detection system, for example, the following method can be adopted: measure the current at 1 / 10000 s to 1 / 100000 s to 1 / n s, measure the short-circuit current such as the sparks and tracking phenomena generated instantaneously, and detect the large current of the sparks and tracking.

[0170] The following method can also be adopted: detect the instantaneous current in units of 1 / 10000 s to 1 / 100000 s to 1 / n s, convert the detected analog current value into an analog voltage value, convert the converted analog voltage value into a digital voltage value, and then convert it into a current value to detect abnormal currents such as sparks and tracking.

[0171] For example, it is a tracking detection system for DC electrical equipment such as the motors of railways and electric vehicles, and DC power supply devices such as solar power generation and storage batteries.

[0172] This 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 a circuit through which a DC current flows.

[0173] <An example of the tracking detection function in the DESCON emergency system>

[0174] The DESCON emergency system can adopt the method with the tracking detection function exemplified in Figure 20 . The tracking detection function can be exerted by the tracking detection system in the above-mentioned DESCON emergency system.

[0175] Based on this tracking current detection function, instantaneous current detectors (CTs) are installed in the corresponding circuits of distribution panels, sub-distribution panels, control panels, and terminal facilities. The CTs detect the analog current value detected within an instantaneous time period. The instantaneous time unit in analog current detection is, for example, 1 second / 12000 (83 μsec) to 1 second / 50000 (20 μsec). Alternatively, it can be proportional to the PC's performance, ranging from 1 second / 100000 (10 μsec) to 1 second / N.

[0176] Next, the analog current value is converted into an analog voltage value. For example, the analog current value detected in the instantaneous time intervals of 1 second / 12000 (83 μsec) ~ 1 second / 50000 (20 μsec) ~ 1 second / 100000 (10 μsec) ~ 1 second / N value (N μsec) is converted into an analog voltage value.

[0177] Next, the analog voltage value is converted into a digital voltage value. That is, the analog voltage value obtained from the above conversion is converted into a digital voltage by A / D conversion.

[0178] Next, the digital voltage value transformed as described above will be converted into a current value.

[0179] Next, based on the current value calculated as described above, the abnormal current is detected and judged.

[0180] For example, an instantaneous current value that suddenly rises to 30 to 100 times the allowable current value is detected and judged as an abnormal current such as a short circuit, spark, or leakage tracking in the corresponding circuit.

[0181] In the aforementioned processing, a structure implemented using a microcontroller or microprocessor in the form of a printed circuit board can be employed. Alternatively, these processes can be executed by a computer's CPU.

[0182] When an abnormal current is detected during the above process, the power supply to the circuit of the corresponding distribution panel will be automatically cut off if it is possible to automatically disconnect the circuit.

[0183] Additionally, alerts will be sent to the relevant personnel's PCs, tablets, smartphones, etc. These alert emails can be sent multiple times until the relevant personnel confirm and reset, enabling a safe recovery response after automatic disconnection.

[0184] Alternatively, one can identify and address the relevant circuit boards and equipment remotely or on-site.

[0185] Like this, the DESCON emergency system possesses... Figure 20In the tracking detection function illustrated in the example, regarding warning sending and automatic cut-off, it can continuously send until the relevant personnel confirm the sent warning and reset it, thus ensuring foolproof control and preventing electrical burnout and electrical fires.

[0186] <An example of the joule heat detection function in the DESCON emergency system>

[0187] The DESCON emergency system can adopt a method with Figure 21 the joule heat detection function illustrated in the example.

[0188] According to the joule heat detection function, monitor the temperature of the connection terminal block of each circuit equipped with a circuit breaker. That is, use a temperature sensor to monitor the temperature rise caused by the joule heat of the connection terminal block.

[0189] Suppose the circuits equipped with circuit breakers (circuit breakers), such as cables, are cables classified by temperature as follows: the allowable temperature of the IV / KIV cable is 60 degrees, the allowable temperature of the VVF cable is 60 degrees, the allowable temperature of the VCT cable is 60 degrees, the allowable temperature of the HIV cable is 75 degrees, the allowable temperature of the CV cable is 90 degrees, the allowable temperature of the MLFC cable is 90 degrees, etc. In this case, based on the allowable temperature of the wire, etc., take the vigilance temperature of the above cables and wires, etc. relative to the allowable temperature, which is arbitrarily set in advance, as the judgment information. For example, the following method can be adopted: store +10 to 15 degrees, etc. in the database, and when the corresponding discs, cables, and circuits reach the vigilance temperature, send a warning to the relevant personnel's PC, tablet, and smartphone in the form of sound, numerical value, and image.

[0190] For example, use a temperature sensor to detect the temperature abnormality caused by the temperature rise due to the looseness, gap, and offset of the connection terminal block, etc.

[0191] When it can be determined as a temperature abnormality and when it can be automatically cut off, automatically cut off the power supply of the circuit of the corresponding distribution board.

[0192] If it rises to a pre-determined temperature, it can automatically cut off the power supply of the electrode supplied to the circuit of the corresponding distribution board. For example, detect and judge the occurrence of spark / tracking phenomenon due to the melting and burning of the covering material of the resistance of the corresponding cable, wire, and circuit, etc., and prevent electrical burnout and electrical fire accidents.

[0193] In this case, a method of sending a warning to the relevant personnel's PC, tablet, smartphone, etc. can be adopted. A method can be adopted to ring the alarm bell until the relevant personnel confirm and reset it, or to send multiple consecutive emails and continuously ring the bell to prevent the relevant personnel from missing the confirmation.

[0194] It is also possible to adopt the method of remotely or on-site confirming the panels and facilities and equipment of the corresponding circuits and taking countermeasures.

[0195] In this way, in the Joule heat detection function exemplified in Figure 21 Regarding the above warning sending and automatic cut-off, it is possible to continuously send until the relevant personnel confirm the sent warning and reset it, thus safely controlling and preventing electrical burnout and electrical fires.

[0196] <An example of the overcurrent detection function in the DESCON emergency system>

[0197] The DESCON emergency system can adopt the method of having Figure 22 the overcurrent detection function exemplified in

[0198] According to this overcurrent detection function, the current values of each circuit equipped with a circuit breaker (breaker) are monitored.

[0199] For example, a current transformer (CT) for instantaneous current value detection is used to monitor the overcurrent of each circuit.

[0200] As the operating time of the circuit breaker for different current values, for example, when the rated current value is 30A, the operating time of the protective cut-off of the corresponding circuit breaker at 1.25 times the rated current value, that is, 37.5A, is 60 minutes or less.

[0201] For example, when the wiring circuit breaker such as a circuit breaker for protecting the circuit is not properly set, due to the generation of overcurrent in the circuit, the current increases, and the wire heats up significantly due to Joule heat. If this state continues, the wire rises to a high temperature, and the insulating material of the wire will melt.

[0202] For example, based on the allowable temperatures of cables and wires with different temperatures 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, etc., the warning temperatures arbitrarily set in advance, for example, for distribution boards, sub-distribution boards, junction boxes, connection devices, terminal devices, connecting various facilities and equipment, electrical equipment / appliances, and the above cables and wires, relative to the allowable temperature can be set as judgment information. For example, store +10 to 15 degrees in the database, and when the corresponding panels, cables, and circuits reach the warning temperature, send warnings to the relevant personnel's PCs, tablets, and smartphones in the form of sound, numerical values, and images.

[0203] An instantaneous current value detector CT (current transformer) is set in each of the above circuits to detect abnormalities in the current value, and a temperature sensor is also used to detect the temperature rise of cables, wires, and connecting metal parts, etc.

[0204] When abnormal current and temperature are detected and automatic cut-off is possible, the power supply of the corresponding distribution board circuit is automatically cut off.

[0205] If the temperature rises to a pre-determined level, the power supply of the corresponding distribution board circuit can be automatically cut off. For example, it can detect and judge the occurrence of spark / leakage tracking phenomenon due to the melting and burning of the covering materials of the corresponding cables, wires and circuits, etc., and prevent electrical burn-out and electrical fire accidents.

[0206] At this time, a warning is sent to the PCs, tablets, smartphones, etc. of relevant personnel. The following methods can be adopted: the alarm bell rings until the relevant personnel confirm and reset it, or multiple emails are sent continuously and the bell rings continuously to prevent the relevant personnel from missing the confirmation.

[0207] It is possible to confirm and respond to the corresponding circuit board and facilities and equipment remotely or on-site.

[0208] In this way, in the overcurrent detection function possessed by the DESCON emergency system Figure 22 as exemplified above, regarding the above warning sending and automatic cut-off, it can be continuously sent until the relevant personnel confirm the sent warning and reset it, thus controlling and preventing electrical burn-out and electrical fire without fail.

[0209] <An example of the leakage current detection function in the DESCON emergency system>

[0210] The DESCON emergency system can adopt a method with Figure 23 the leakage current detection function exemplified above.

[0211] According to this leakage current detection function, a leakage current value detector ZCT (zero-phase current transformer) is used to monitor the leakage overcurrent of each circuit equipped with a circuit breaker (circuit breaker).

[0212] When abnormal leakage overcurrent of the circuit is detected by ZCT, for example, when it reaches a predetermined leakage current value and automatic cut-off is possible, the power supply that provides electrodes to the corresponding distribution board circuit is automatically cut off. For example, it can detect and judge insulation defects such as aging of the corresponding cables, wires and circuits, and prevent electrical burn-out, electrical fire accidents and electric shock accidents.

[0213] It is possible to adopt a method of sending a warning to the PCs, tablets, smartphones of relevant personnel in the form of sound, numerical value and image when the leakage current value detected by ZCT reaches the warning current value. The following methods can be adopted: the alarm bell rings until the relevant personnel confirm and reset it, or multiple emails are sent continuously and the bell rings continuously to prevent the relevant personnel from missing the confirmation.

[0214] It is possible to confirm and respond to the corresponding circuit board and facilities and equipment remotely or on-site.

[0215] In this way, in the leakage current detection function possessed by the DESCON emergency system, Figure 23 as exemplified above, regarding the above-mentioned warning sending and automatic cut-off, it can continuously send until the relevant personnel confirm the sent warning and reset it, thus ensuring foolproof control and prevention of electrical burnout and electrical fires.

[0216] <An example of the circuit breaker system in the DESCON emergency system>

[0217] The above-mentioned DESCON emergency system can adopt a structure with a circuit breaker system having the following description.

[0218] As Figure 19 shown in an example, this circuit breaker system is a system that embeds and incorporates the above-mentioned tracking detection function, joule heat detection function, overcurrent detection function, leakage current detection function, and automatic cut-off function in the DESCON emergency system into a wiring circuit breaker (circuit breaker) to prevent electrical fires and burnout accidents.

[0219] 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 all incorporated into the circuit breaker (circuit breaker).

[0220] Thus, this circuit breaker system adopts the following method: for tracking, joule heat, overcurrent, leakage current, etc., for example, taking the main circuit breaker (wiring circuit breaker) of each individual circuit such as a distribution board, sub-distribution board, control board, electrical equipment, load device, etc. as a unit, it detects abnormalities in tracking, joule heat, overcurrent, and leakage current, and when detecting abnormal values of a predetermined tracking current, temperature, overcurrent, and leakage current, it sends warnings to the PCs, tablets, smartphones, etc. of the relevant personnel through sounds and images.

[0221] It can also adopt the following method: when detecting a predetermined alarm current, alarm temperature, and alarm leakage current, it sends warnings to the PCs, tablets, smartphones, etc. of the relevant personnel through sounds and images, and automatically cuts off the corresponding circuit or main circuit breaker.

[0222] As Figure 19 shown, this kind of circuit breaker system can be called a DESCON intelligent circuit breaker system.

[0223] <Various embodiments and functions of the DESCON emergency system of the present invention>

[0224] The structure of the DESCON emergency system is as follows: It detects the current, voltage, temperature, and images of substations, distribution panels, sub-distribution panels, control panels, main lines, circuits, circuit breakers, remote devices, load terminal facilities, and electrical equipment. It refers to various pre-entered databases to determine whether the values ​​are normal or abnormal. For example, it uses the values ​​in the abnormal value list as warning signals for the abnormal warning stage. It uses information such as sound, numerical values, and images to send warnings to relevant personnel, such as customer name, building name, facility name, location, type and capacity of lights and power for the corresponding panel and circuit, electrical facilities at the system terminal, and load facility names. The system sends warnings in real time on PCs, tablets, and smartphones using sound, images, and numerical values.

[0225] The following implementation methods can be adopted: According to the DESCON emergency system, if the abnormal value becomes high, it can "send an alarm signal with sound, image and value", "automatically disconnect the corresponding facilities such as panels, trunk lines, circuits and circuit breakers", "send an alarm to relevant personnel with sound, image and value to indicate that the automatic disconnection has been completed", "send continuously until relevant personnel confirm and reset", and "respond safely to the recovery after automatic disconnection in real time".

[0226] Regarding the aforementioned automatic shut-off, for example, when automatically shutting off the corresponding terminal facilities and electrical equipment of various facilities and electrical equipment such as goods manufacturing and logistics centers, large freezers and refrigerators, commercial facilities with large gatherings of people, airport terminals and hotels, data centers containing important data research and experimental results, infrastructure substations, and transportation agencies such as electric trains and ships, when these are controlled by a computer based on a computer program, the terminal equipment such as the control unit is shut down according to a predetermined program. 2) For distribution panels, sub-distribution panels, control panels, main lines, circuits and circuit breakers, etc., the DESCON emergency system, composed of remote devices of each system, cloud servers and LANs, etc., uses emergency response protection professional programs to send signals to the protection stop devices through the remote devices of each system, cloud servers and LANs. The batch or selected terminal devices of the control, etc. have the function of shutting down using a predetermined program. It is characterized by a function control unit for normal and safe stopping and a function control unit for confirming the stop signal.

[0227] The DESCON emergency system can be implemented as follows: Whether the current, voltage, insulation, and temperature of the aforementioned facilities, main lines, circuits, circuit breakers, terminal load facilities, and electrical equipment are normal or abnormal is determined by using pre-defined programs on relevant personnel's PCs, tablets, and smartphones. These programs use parameters such as customer name, building name, facility name, location, and circuit settings to calculate and determine the values ​​for year, season, month, week, day, hour, and minute, and to compare these values ​​with other timeframes. The system records the current, voltage, insulation, and temperature values, along with whether they are normal or abnormal, in a database. This information is then periodically displayed or automatically printed to the relevant personnel's PCs, tablets, smartphones, and monitors using the program.

[0228] The DESCON emergency system can be implemented as follows: It is interconnected with fire alarms in building facilities such as fire prevention panels, receives abnormal signals from smoke and heat detectors of the fire alarm, determines the floor and area of ​​the received signal, and automatically cuts off predetermined lights and power supplies to the aforementioned facilities except for those required for refuge, fire alarms, emergency guidance lights, lighting, mechanical smoke extraction, and gas supply, etc., using sound, images, and numerical data via PC, tablet, or smartphone. The system continuously sends alerts to relevant personnel in real time, including information such as customer name, building name, facility name, location, corresponding panel and circuit, as well as the type and capacity of lights and power supplies, until the relevant personnel confirm and reset the system. It can safely respond to the restoration after automatic shutdown in real time.

[0229] The DESCON emergency system can be implemented as follows: On the connecting metal parts of the distribution panels, sub-distribution panels, control panels, terminal facilities, and motor facilities of the substation system, dust and grime may accumulate over time. This can lead to leakage and tracking due to moisture or loosening of the connecting metal parts, circuits, and terminal metal parts proportional to the passage of time. In this case, pre-set alarm and alert temperatures are programmed. If the alarm temperature is reached, an alert is sent to relevant personnel's PCs, smartphones, tablets, etc., including information such as customer name, building name, facility name, location, and the type and capacity of lights and power for the corresponding panel and circuit. This continues until the relevant personnel confirm and reset the settings. The system also automatically disconnects the corresponding cables and circuits, alerting relevant personnel to the automatic disconnection status. This continues until the relevant personnel confirm and reset the settings, ensuring safe recovery after automatic disconnection.

[0230] The DESCON emergency system can be implemented as follows: On the connecting metal parts of the distribution panels, sub-distribution panels, control panels, terminal facilities, and motor facilities of the substation system, dust and grime may accumulate over time. Due to moisture or loosening and gaps in the connecting metal parts, circuits, and terminal metal parts proportional to the passage of time, the electrical resistance value increases, causing Joule heating in the wiring and circuits to exceed the allowable temperature for each wire type. The temperature of each wire exceeds the allowable temperature for its corresponding type. Because the electrical insulation covering material deforms and melts proportionally to the high temperature, short circuits occur between positive and negative charges. In the event of an electrical fire caused by a spark or other source of electricity, the system can pre-set and programmatically input parameters such as alert and alarm temperatures. If the alarm temperature is reached, it will send alerts to relevant personnel's PCs, smartphones, tablets, etc., including information such as the customer's name, building name, facility name, location, and the type and capacity of the lights and power supply for the corresponding panel and circuit. This will continue until the relevant personnel confirm and reset the settings. The system will also automatically disconnect the corresponding cables and circuits, and alert relevant personnel to the automatic disconnection status. This will continue until the relevant personnel confirm and reset the settings, ensuring safe recovery after automatic disconnection.

[0231] The DESCON emergency system can be implemented as follows: Due to the aging of metal parts, terminals, cables, wiring, and circuits connecting to the distribution panels, sub-distribution panels, control panels, terminal facilities, and motor facilities of the substation system, the conductive area decreases due to loosening and gaps in the connecting metal parts, resulting in resistance heat. The temperature rises proportionally to the passage of time due to Joule heating, which may reach or exceed the allowable temperature of each wire. At this time, a pre-set alert temperature and alarm temperature are programmed. If the alarm temperature is reached, an alert is sent to the relevant personnel's PC, smartphone, tablet, etc., with information such as customer name, building name, facility name, location, and the type and capacity of lights and power of the corresponding panel and circuit. The alert is sent continuously until the relevant personnel confirm and reset. The system also sends and automatically cuts off the corresponding cables and circuits, and sends an alert to the relevant personnel that the automatic disconnection has been completed. The alert is sent continuously until the relevant personnel confirm and reset, thus safely handling the restoration after the automatic disconnection.

[0232] The DESCON emergency system can be implemented as follows: Within a very short time, it detects dust and dirt adhering to various panels, connecting metal parts, terminals, circuits, and terminal equipment; moisture caused by humidity; or the melting and burning of insulation materials in the wires and circuits due to Joule heating caused by the temperature rise of these components. It uses a short-circuit and spark current value, for example, 50 to 80 times the normal current (i.e., a pre-set 50 to 80 times current value), as a warning signal for short circuits and sparks. This signal is sent to relevant personnel's PCs, smartphones, tablets, etc., indicating information such as customer name, building name, facility name, location, and the type and capacity of lights and power in the corresponding panel and circuit. The system automatically disconnects the corresponding panel and circuit, repeatedly notifying relevant personnel of the automatic disconnection status until confirmation and reset. This ensures safe recovery after automatic disconnection.

[0233] For extremely short detection times, such as 1 / 12000 of a second = 83 microseconds, it can be set as an instantaneous detection. Here, 12000 is, for example, a common multiple of 50 Hz and 60 Hz.

[0234] The DESCON emergency system is as follows: For overcurrents exceeding the rated current, based on the current (A) of the above-mentioned power transformation and distribution facilities, switchboards, distribution boards, control panels, terminal facilities, motor facilities, etc., as well as main lines and circuits, such as below 30A rated current, 30A to 50A below, …, 445A to 400A below, 800A to 1000A below, and 1600A to 2000A below, etc., and the relationship of the safety protection of electrical facilities where the operating time of the allowable current circuit breaker is 60 minutes or less when the allowable current = 1.25 times the rated current and the operating time of the allowable current circuit breaker is 6 minutes to 120 minutes or less when the allowable current is 2.0 times the above-mentioned rated current. If each current exceeds the rated current and reaches the specified time, the circuit breaker operates. However, for example, the required current for the预定单体 and相互连接等 of the corresponding terminal load facilities and motor facilities, etc. is not the above-mentioned set current value for the circuit breaker to operate, but due to weak overcurrents or aging that require long time, the insulating material covering material is damaged. When the above facilities operate 24 hours a day throughout the year, according to the overload current situation, etc., before the operating factor of the load factor of the high-voltage transformer of the power transformation and distribution facilities reaches the allowable factor based on the overcurrent situation of the above facilities, such as the maximum allowable temperature, the vigilance temperature and vigilance current are arbitrarily set in advance, and warning messages are sent to the PCs, smartphones, tablets, etc. of relevant personnel, such as customer name, building name, facility name, location, types and capacities of lighting and power of the corresponding panel and circuit, etc., and sent multiple times until the relevant personnel confirm and reset. Before the operating factor of the load factor of the low-voltage lighting and power reaches the allowable factor for the lighting and power installed capacity of the above facility, for the corresponding low-voltage lighting, power switchboard, lighting, power distribution board, control panel, terminal load facilities, motor facilities, etc., automatic cut-off is arbitrarily set in advance without priority and automatic cut-off is carried out, thereby reducing the maximum allowable temperature of the transformer of the above power transformation and distribution facilities, the load factor overcurrent factor of the allowable current. The DESCON emergency system can adopt the following implementation method: Carry out automatic cut-off, send warning messages to relevant personnel about the situation of automatic cut-off, and continuously send until the relevant personnel confirm and reset, and it is also possible to safely handle the restoration after automatic cut-off.

[0235] <Flow chart of an implementation method of the tracking detection function in the DESCON emergency system>

[0236] An alternating current instantaneous current value detector is set in the corresponding circuits of switchboards, distribution boards, control panels, and terminal facilities, etc. to detect the analog current value detected within an instantaneous time. Detect the instantaneous current value of the corresponding circuits of switchboards, distribution boards, control panels, and terminal facilities, etc.

[0237] Regarding the "预定单体 and相互连接等" in the original text, it seems there are some unclear or incorrect expressions. I've translated it as best as possible based on the context, but it might need further clarification in the original content.As an AC instantaneous current detector, a current sensor using an instrument converter called a CT (current transformer) can be used. Furthermore, in this specification and accompanying drawings, the AC instantaneous current detector is sometimes simply referred to as "CT".

[0238] As mentioned above, as a detection of instantaneous time, it can be, for example, a detection of 1 / 12000 seconds obtained by dividing by the common multiple of 50Hz and 60Hz, i.e., 50×60×4=12000.

[0239] As described above, the instantaneous time unit in instantaneous time detection is, for example, 1 / 12000 of a second = 83 microseconds, and can be arbitrarily set between 1 / 50000 (=20 μsec) and 1 / 100000 of a second (=10 μsec). Alternatively, it can be set to a microsecond within this range that is proportional to the performance of the computer (PC) constituting the DESCON emergency system.

[0240] The instantaneous time unit in the instantaneous time detection will be set to microseconds between 1 / 50000 (=20μsec) and 1 / 100000 (=10μsec). This will help to detect the danger of tracking more quickly so that necessary measures such as power cut-off can be taken before tracking occurs.

[0241] Next, the instantaneous current value detected as described above is compared with the preset allowable current value to determine the short circuit, spark, and leakage tracking phenomena of the corresponding circuit.

[0242] For example, an instantaneous current value that suddenly surges to the corresponding circuit of the distribution panel, sub-distribution panel, control panel, and terminal facilities, i.e., a multiple of 30 times the allowable current value, is judged as an abnormal current that causes short circuits, sparks, and leakage tracking in the corresponding circuit.

[0243] The current value that is judged as an abnormal current value can be arbitrarily set within the range of 30 to 100 times the allowable current value of the corresponding circuit of the distribution panel, sub-distribution panel, control panel and terminal facilities.

[0244] Furthermore, as described above, after detecting the instantaneous current value using the analog current value, the process of converting the analog current value into an analog voltage value can be performed.

[0245] For example, the analog current values ​​detected in instantaneous time intervals such as 1 / 50000 (=20μsec) to 1 / 100000 (=10μsec), such as 1 / 12000 (83μsec), are converted into analog voltage values.

[0246] At this time, next, the analog voltage is converted (A / D converted) into a digital voltage, and then the digital voltage is converted into a digital current value. For example, using a computer program, through the processing work performed by the CPU of the computer, the digital voltage value after the A / D conversion as described above is converted into a digital current value.

[0247] The following implementation method can also be adopted: the digital current value converted in this way is regarded as the detected instantaneous current value. As described above, it is compared with the preset allowable current value to determine the short circuit, spark, and tracking phenomenon of the corresponding circuit, etc.

[0248] When the detected instantaneous current value is compared with the preset allowable current value and judged as an abnormal current that causes the short circuit, spark, and tracking phenomenon of the corresponding circuit, etc., it is judged whether the automatic cut-off of the corresponding circuit of the distribution board, sub-distribution board, control panel, and terminal facilities, etc. can be performed.

[0249] When it is judged that automatic cut-off can be performed, the power supply of the corresponding circuit is automatically cut off.

[0250] On the other hand, when it is judged that the corresponding circuit with abnormal current is controlled by a computer or the like and it is necessary to first cut off the computer or the like for control and then cut off the power supply, the following structure can be adopted: first cut off the power supply to the computer or the like for control, and then cut off the power supply.

[0251] Send a warning to the relevant personnel's PCs, tablets, smartphones, etc. Sending warning emails multiple times until the relevant personnel confirm and reset is a system that can safely handle the recovery after automatic cut-off. Confirm the corresponding circuit board and facility equipment remotely or on-site and take corresponding measures.

[0252] <Joule heat detection function flow of the DESCON emergency system>

[0253] Monitor the temperature of the wires and connecting metal parts of each circuit

[0254] Use a temperature sensor to monitor the temperature rise of cables and wires caused by Joule heat.

[0255] For example, it features the following judgment unit: Based on the allowable temperatures of cables and wires with different temperatures such as the allowable temperature of IV / KIV being 60 degrees, the allowable temperature of VVF being 60 degrees, the allowable temperature of VCT being 60 degrees, the allowable temperature of HIV being 75 degrees, the allowable temperature of CV being 90 degrees, and the allowable temperature of MLFC being 90 degrees, etc., with respect to a pre - arbitrarily set allowable temperature, for example, for a distribution board, sub - distribution board, junction box, connection device, terminal device, connecting various facility equipment, electrical equipment / appliance, the warning temperature of the above - mentioned cables and wires, etc. is judged. For example, +10 to 15 degrees is stored in the database in advance. When the corresponding boards, cables, and circuits, etc. reach the warning temperature, a warning sound, value, and image are sent to the PCs, tablets, and smartphones of relevant personnel.

[0256] Detect temperature anomalies: Use a temperature sensor to detect the temperature rise caused by looseness, gaps, and offsets, etc. of connection terminal blocks, etc.

[0257] When automatic cut - off is possible, automatically cut off the power supply of the corresponding sub - distribution board circuit.

[0258] It features the following unit: If the temperature rises to a predetermined temperature, automatically cut off the power supply of the corresponding sub - distribution board circuit, detect and judge phenomena such as sparking / leakage tracking due to melting and burning of the covering materials of the resistance of the corresponding cables, wires, and circuits, etc. This can prevent electrical burnout and electrical fire accidents.

[0259] Send a warning to the PCs, tablets, smartphones, etc. of relevant personnel.

[0260] This is a system that rings an alarm bell until relevant personnel confirm and reset it, or sends multiple consecutive emails with continuous ringing to prevent relevant personnel from missing the confirmation.

[0261] Confirm the boards and facility equipment of the corresponding circuit remotely or on - site and take countermeasures.

[0262] <An example of the over - current detection function process of the DESCON emergency system>

[0263] Monitor the over - current of each circuit

[0264] Set an alternating - current instantaneous current value detector CT in the corresponding circuits of distribution boards, sub - distribution boards, control panels, and terminal facilities, etc. to monitor the over - current of each circuit.

[0265] The operating times of circuit breakers with different current values are as follows: For example, if the rated current value is 30A, the operating time of the protection cut - off of the corresponding circuit breaker with 1.25 times the rated current value, i.e., 37.5A, is 60 minutes or less.

[0266] For example, if the wiring circuit breaker or other circuit breaker used to protect the circuit is not properly installed, an overcurrent will occur in the circuit, causing the current to increase. As a result, the wires will heat up significantly due to Joule heating. If this situation continues, the wires will rise to a high temperature and the insulation material will melt.

[0267] For example, the feature is the following judgment unit: using the allowable temperatures of cables and wires of different temperatures, such as IV / KIV (60 degrees), VVF (60 degrees), VCT (60 degrees), HIV (75 degrees), CV (90 degrees), and MLFC (90 degrees), as a benchmark, relative to a pre-set allowable temperature, the unit judges the alert temperature of, for example, distribution panels, junction boxes, connection equipment, terminal equipment, connecting facilities and equipment, electrical equipment / instruments, and the aforementioned cables and wires. For example, +10~15 degrees is stored in a database. When the corresponding panels, cables, and circuits reach the alert temperature, the unit sends sound, numerical values, and images to the relevant personnel's PCs, tablets, and smartphones as an alert.

[0268] Detecting abnormal current and temperature

[0269] AC instantaneous current detectors (CTs) are installed in each of the above circuits to detect abnormal current values. Temperature sensors are also used to detect temperature rises in cables, wires, and connecting metal parts.

[0270] When automatic disconnection is possible, the power supply to the corresponding distribution panel circuit will be automatically cut off.

[0271] The feature is that if the temperature rises to a predetermined level, the power supply to the circuit of the corresponding distribution panel is automatically cut off, and the phenomenon of sparking / tracking due to melting or burning of the covering material of the corresponding cable, wire and circuit is detected and judged, for example, due to the resistance of the covering material of the corresponding cable, wire and circuit, etc. This can prevent electrical burns and electrical fire accidents.

[0272] Send alerts to the PCs, tablets, smartphones, etc. of relevant personnel.

[0273] This is a system that rings an alarm until the relevant personnel confirm and reset it, or sends multiple emails and rings continuously to prevent the relevant personnel from missing confirmation.

[0274] Identify and address the relevant circuit boards and equipment remotely or on-site.

[0275] One to n Joule heat / current detection devices can be set arbitrarily on the power line.

[0276] The detection device can be connected to a power cord but not to a network.

[0277] Each detection device can be connected directly to the upstream remote device in a manner that can send signals to the remote device.

[0278] The above-mentioned joule heat / current detection device can be directly connected to the remote device outside the control panel. In addition, it can also be the case that 1 to n joule heat / current detection devices (P4 to P5) arbitrarily set on the power line are directly connected to the remote device 2 inside the control panel.

[0279] <An embodiment of the process when cutting off is performed upon detecting temperature / current abnormality>

[0280] The above-mentioned joule heat / current detection device sends the value of the internal organ sensor to the remote device.

[0281] When detecting an abnormality in temperature / current, the remote device makes the corresponding circuit breaker operate to cut off.

[0282] The central control device constituting the DESCON emergency system sends a cut-off notice to the PCs, tablets, smartphones, etc. of relevant personnel through the cloud server.

[0283] <Other embodiments of the process when cutting off is performed upon detecting above temperature / current>

[0284] The joule heat / current detection device sends the value of the internal organ sensor to the corresponding remote device.

[0285] When detecting above temperature / current, the corresponding remote device makes the corresponding circuit breaker operate to cut off.

[0286] The central control device constituting the DESCON emergency system sends a cut-off notice to the PCs, tablets, smartphones, etc. of relevant personnel through the cloud server.

[0287] <The arrangement method of the joule heat / current detection device>

[0288] In the information system network (A) and the control system network (B) constituting the DESCON emergency system, the Internet (open public network) can be used as the WAN (wide area network) part. There will be no particular problem in using the Internet when sending a cut-off notice to the PCs, tablets, smartphones, etc. of relevant personnel.

[0289] However, except for sending a cut-off notice, regarding the connection between bases, when performing remote access, for security considerations, it is generally considered to use a dedicated line or VPN (closed network) instead of the Internet. At this time, the WAN part can be replaced as needed.

[0290] <The tracking resistance detection function of the DESCON emergency system>

[0291] Traditional electrical protection circuit breakers and the like have the following safety protection functions: for example, regarding the measurement time of current, in the case of ammeters (CTs) and the like, it is measured in hours, minutes and seconds; at a power frequency of 50 Hz, it is usually measured in 0.1 sec (100 msec); at 60 Hz, it is usually measured in 0.083 sec (83 msec); and thermal circuit breakers and residual current circuit breakers have safety protection functions such as overcurrent and leakage current protection for electrical facilities, cutting off the corresponding circuit.

[0292] However, the current state of conventional protective circuit breakers is as follows: for transient short circuits and sparks that occur momentarily in the aforementioned corresponding parts, residual current circuit breakers, which operate under thermal action in the past, such as those used for main lines, cables, and wiring, typically measure at a power frequency of 50 Hz (usually 0.1 sec (100 msec)) and 60 Hz (usually 0.083 sec (83 msec)), do not sense or protect against transient electrical burnouts and fires, which can lead to electrical burnouts and electrical fires.

[0293] In the DESCON emergency system, CTs are installed in the corresponding circuits of distribution panels, sub-distribution panels, control panels, and terminal facilities.

[0294] The analog current values ​​detected by the CT in instantaneous time intervals of 1 / 50000 (=20μsec) to 1 / 100000 (=10μsec), such as 1 / 12000 (83μsec), are converted into analog voltage values. These are then converted into instantaneous digital voltages in the instantaneous time intervals of 1 / 50000 (=20μsec) to 1 / 100000 (=10μsec), such as 1 / 12000 (83μsec), using a computer, PC, or microcontroller. Finally, the voltages are converted into digital currents using a pre-defined program on the printed circuit board.

[0295] The digital voltage value is converted into a digital current value by converting the digital voltage into current in the above manner. The current value of the abnormal phenomenon of instantaneous surge of short circuit and spark in the corresponding circuit is detected within an instantaneous time period of, for example, arbitrarily set 1 / 50000 (=20μsec) to 1 / 100000 (=10μsec), such as 1 / 12000 (83μsec).

[0296] Next, the power frequency, for example, 50Hz, 60Hz, or other frequencies, will be used to convert the instantaneous analog current (CT current) value of phenomena such as short circuits, sparks, and tracking current that occur in the aforementioned facilities into voltage. For example, an analog-to-digital converter (A / DC) is installed in the corresponding circuit to convert the detected analog current value into a digital voltage value. For the converted digital voltage value, the analog current value detected within an instantaneous time interval, such as arbitrarily set from 1 / 50000 (=20μsec) to 1 / 100000 (=10μsec), or for example, 1 / 12000 (83μsec), is converted into an analog voltage value and then into a digital voltage. A predetermined alert current / multiplier and alarm current / multiplier are determined based on the multiplier factor of the conventional current. Based on this, the alert current / multiplier and alarm current / multiplier are sent to the PCs, tablets, and smartphones of relevant personnel.

[0297] The DESCON emergency system installs the aforementioned current detection device (CT) in the corresponding circuit to detect current. It uses the functions of devices such as computers, PCs, microcontrollers, and printed circuit boards to convert current into voltage. The current is converted into voltage, and the analog-to-digital converter is used to detect instantaneous currents of, for example, 1 / 12000 second = 83 μsec at power frequencies of, for example, 50 Hz and 60 Hz.

[0298] Instantaneous current is detected in units of 83μsec = 1 / 12000 seconds. The detected analog current is converted into an analog voltage value, and the converted analog voltage value is converted into a digital voltage value by an A / D converter. The CPU then converts the digital voltage value into a current value to detect abnormal currents such as sparks and tracking.

[0299] For example, the current value detected by CT in 1 / 12000-second (83μsec) hour / minute / second intervals is converted into voltage. The denominator is the negative current detected for the first time, starting from 0A when the current A reverses from a positive to a negative AC current, such as -1.4A, and the current before the current that is more than 15 times the predetermined conventional current A, such as -81.7A, is multiplied by 19.9 times, such as -4.1A. For each 80μsec unit current, the conventional multiple of each current A is calculated using the denominator -4.1A and the average negative current of -2.0A from the above negative currents -1.4A to -4.1A, for example, by three methods, at an 83μsec interval of 1 second / 12000 detections.

[0300] In addition, if the detected current is detected as an open-circuit current of 0A, it can be converted to 1.0 as the denominator regardless of whether the current is positive or negative.

[0301] The DESCON emergency system can perform the following controls: using a pre-set, for example, 15 times multiplier as the prediction multiplier for spark / tracking phenomena, the program will determine that a spark / tracking phenomenon occurs when the multiplier exceeds 20 times, and will send an alert to the relevant personnel's PCs, smartphones, tablets, etc. When the multiplier exceeds 25 times, it will automatically cut off the corresponding circuit.

[0302] The DESCON emergency system can employ the following method: regarding the aforementioned warnings and automatic disconnection, it can continuously send multiple warnings until relevant personnel confirm the sent warnings and reset them, thereby ensuring foolproof control and prevention of electrical burnout and electrical fires.

[0303] Based on the above, for example, the following system can be used: measure the current at frequencies of 50Hz and 60Hz at 83μsec (1 / 12000 seconds), measure the short-circuit current of instantaneous sparks and tracking phenomena, and detect the large current of sparks and tracking phenomena.

[0304] In the structure of the DESCON emergency system, AC instantaneous current detectors (CTs) are installed in the corresponding circuits of distribution panels, sub-distribution panels, control panels, and terminal facilities to detect the simulated current value within an instantaneous time period. The instantaneous time unit is as mentioned above, for example, it can be 1 / 50000 (=20μsec) to 1 / 100000 second (=10μsec), such as 1 / 12000 second (83μsec), etc.

[0305] The DESCON emergency system detects abnormal current values ​​such as short-circuit sparks and tracking based on instantaneous current values ​​in the range of 1 / 50000 (20 μsec) to 1 / 100000 (10 μsec), for example, 1 / 12000 (83 μsec) per hour / minute / second. For instance, based on verification data from lighting installations, the DESCON system detects current values ​​in units of 1 / 12000 (83 μsec). The current multiplier immediately following AC reversal and before tracking occurs is calculated as: A / -1.4A for each current; the average current multiplier from 4.15 ms to 7.47 ms after AC reversal is calculated as: A / -2.0A for each current; and the current multiplier immediately following tracking occurs is calculated as: A / -4.1A, etc. By converting the current values ​​to an arbitrarily set 1 / 12000 (83 μsec) current value, the system detects current values ​​for short circuits, sparks, and tracking.

[0306] For example, for an electric lighting facility, the following current values are detected in units of 83 μsec of elapsed time: current magnification immediately after AC inversion and before tracking initiation = each current A / -1.4 A, magnification of the average current from 4.15 ms to 7.47 ms after AC inversion = each current A / -2.0 A, current magnification immediately before tracking initiation = each current A / -4.1 A, etc. For current values that suddenly rise to a magnification of, for example, 30 to 100 times the allowable current value, they are determined as short - circuit, spark, and tracking initiation phenomena. A warning is sent to the PCs, smartphones, tablets, etc. of relevant personnel regarding the above - mentioned current value magnification of, for example, 10 to 50 times, which is arbitrarily set in advance, and it is sent multiple times until the relevant personnel confirm and reset it.

[0307] Taking the above - mentioned current values and magnifications of, for example, 20 to 70 times, which are arbitrarily set in advance, as alarm current values and magnifications, the corresponding circuits of the corresponding low - voltage electric lights, power distribution panels, control panels, terminal load facilities, and motor facilities, etc. are automatically cut off, and a warning is sent to relevant personnel indicating that the automatic cut - off has occurred. It is sent multiple times until the relevant personnel confirm and reset it, and it can safely handle the restoration after the automatic cut - off.

[0308] Nevertheless, the conventional current value, that is, the allowable current of each wire or the required current value of the terminal load facilities and motor facilities connected to the corresponding panel, etc. can be used as the denominator. Similarly to the above, a current value magnification of, for example, 30 to 100 times relative to this current value, which suddenly rises during short - circuit, spark, and tracking initiation phenomena, is set.

[0309] <An example of the structure of the DESCON emergency system>

[0310] An alternating - current instantaneous current value detector (CT) is set in the corresponding circuits of distribution boards, switchboards, control panels, and terminal facilities, etc. to detect the analog instantaneous current value in units of 83 μsec = 1 / 12000 seconds.

[0311] Analog current - voltage conversion: The detected analog current value is converted into an analog voltage value.

[0312] A / D conversion: The converted analog voltage value is A / D - converted into a digital voltage.

[0313] The digital voltage is converted into current: The CPU converts the converted digital voltage value into a current value, and abnormal currents such as tracking initiation current in the corresponding circuit are detected in units of 83 μsec = 1 / 12000 seconds.

[0314] Install the above current detection device (CT) in the corresponding circuit to detect the current and convert the current into voltage. For example, convert the current into voltage through the function of a printed circuit board such as an IC. In a system that converts current into voltage, for example, a method of detecting the common multiple of power frequencies 50HZ and 60HZ, that is, the instantaneous current of 12,000 times per second = 83μsec, can be adopted.

[0315] Above, for example, taking the current A detected in units of 83μsec, the negative current -1.4A first detected from 0A where the positive number of alternating current power reverses to a negative number, the current -81.7A which is more than 15 times of any predetermined normal current A, and the current -4.1A before multiplying by 19.9 times as the denominator, for each current in units of 80μsec, use the denominator -4.1A and the average negative current -2.0A of the above negative current -1.4A to negative current -4.1A, and calculate the normal magnification of each current A in 83μsec detected at 1 / 12000 times per second through three methods or the like, for example.

[0316] In addition, if the detected normal no-load current is 0A, it can be converted to 1.0 as the denominator regardless of the positive or negative of the current.

[0317] The DESCON emergency system can adopt the following method: have a judgment unit, take a prediction magnification of, for example, 15 times arbitrarily set in advance as the spark / leakage tracking phenomenon, input the above positive / negative current into the program, judge it as a spark / leakage tracking phenomenon when it is more than 20 times, send a warning to the PC, smartphone, tablet, etc. of relevant personnel, and perform control to automatically cut off the corresponding circuit when it is more than 25 times.

[0318] The DESCON emergency system can adopt the following method: regarding the above warning sending and automatic cutting off, continuously send it multiple times until the relevant personnel confirm the sent warning and reset it, so as to safely control and prevent electrical burnout and electrical fires.

[0319] AC instantaneous current value detector CT: Detect the analog instantaneous current value in units of 83μsec = 1 / 12000 seconds.

[0320] Analog current-voltage conversion: Convert the detected analog current value into an analog voltage value.

[0321] A / D conversion: Perform A / D conversion on the converted analog voltage value into a digital voltage.

[0322] Convert the digital voltage into current: The CPU converts the converted digital voltage value into a current value to detect abnormal currents such as leakage tracking current in the corresponding circuit.

[0323] <An example of the system process of the DESCON emergency system>

[0324] An AC instantaneous current detector (CT) is installed in the corresponding circuits of the distribution panel, control panel, and terminal facilities to detect the current in the corresponding circuit in units of 83 μsec = 1 / 12000 seconds, thereby detecting abnormal current values ​​of spark / tracking phenomena.

[0325] As part of the DESCON emergency system, AC instantaneous current detectors (CTs) are installed in the electrical facilities, such as the main and distribution panels of low-voltage lighting / power facilities, branch lines of various systems, distribution panels, control panels, control panels of terminal facilities, and other pre-required panels and wiring. Each current A is input to the remote device of the DESCON emergency system, and the analog data of the CT is converted into voltage, for example, the digital voltage is converted into a current of 83μsec.

[0326] Using the central control unit of the computer that constitutes the DESCON emergency system, the current of the corresponding circuit is input into the database at 83μsec. If the current reaches a multiplier of a pre-set current A, an alarm is sent. If the current exceeds the predetermined current A, the corresponding circuit is automatically cut off and data is sent to the server device composed of the computers that constitute the DESCON emergency system. The data is then sent to the PCs, smartphones, and tablets of the headquarters or relevant personnel to prevent sparks / tracking phenomena in advance.

[0327] The DESCON emergency system sends warnings and automatically cuts off power multiple times until the relevant personnel confirm the warning and reset the system, thus ensuring foolproof prevention of electrical burnout and electrical fires.

[0328] <Structure of the remote devices constituting the DESCON emergency system>

[0329] Visceral remote device

[0330] CTs are installed in the corresponding circuits of distribution panels, control panels, and terminal facilities, and remote devices (sometimes called "DESCON remote devices") are installed in the corresponding panels to detect abnormal currents such as leakage current and tracking current in the corresponding circuits in units of 83μsec = 1 / 12000 seconds.

[0331] Separate type (= non-visceral type) remote device

[0332] CTs are installed in the corresponding circuits of distribution panels, control panels, and terminal facilities, and DESCON remote devices are installed near the corresponding panels to detect abnormal currents such as leakage current and tracking current in the corresponding circuits in units of 83μsec = 1 / 12000 seconds.

[0333] As a remote device in the DESCON emergency system, it can respond using the aforementioned built-in and separate types, depending on the shape and condition of the corresponding disk, etc.

[0334] The aforementioned remote device in the DESCON emergency system is used to detect abnormal short-circuit currents such as sparks and tracking, thereby achieving the above-mentioned functions.

[0335] The DESCON emergency system, for example, converts the instantaneous current values ​​(simulated instantaneous current values) that cause sparking / tracking phenomena from low-voltage distribution panels, sub-distribution panels, control panels, load terminal facilities / electrical equipment, such as secondary-side terminal equipment sockets, into analog voltages. It then converts the analog voltages into digital voltages measured at 1 second / 12000, or for example, 83 μsec. The connected CPU verifies the short-circuit and spark currents of the 83 μsec digital voltage measurement data.

[0336] Using the normal current A measured in the above manner as the denominator of the constant current, the system detects a pre-set current, such as an instantaneous current measured at 83μsec, which is 20 or 25 times higher than the constant current. It automatically makes a judgment and sends warnings to relevant personnel via PCs, smartphones, tablets, etc., regarding the building, floor, area, layout, and information such as the spark leakage current A and the multiplier. It has the protection function of automatically cutting off the corresponding circuits, main lines, connecting metal parts, control panels, or terminal load facilities, electrical equipment, and electrical machinery.

[0337] The following implementation method can be adopted: send warnings multiple times until relevant personnel confirm the sending of the warning and reset it, so as to prevent electrical burnout and electrical fire accidents without any chance of failure, and implement the functional restoration and safety response of the corresponding facilities in real time.

[0338] For example, as data, it is the instantaneous current value obtained by measuring 12,000 times per second, which is a common multiple of the power frequency of 50 Hz and 60 Hz, at 83 μsec.

[0339] Single-phase 100V, 50Hz

[0340] Circuit breaker capacity: 20A

[0341] Loading device: 200W incandescent bulb

[0342] Rated current: 2A

[0343] Instantaneous current measurement sampling period: in units of 83 μsec: 1 μsec = 1 / 1000 m second = 1 / 1000000 second

[0344] The DESCON emergency system can be implemented with the following judgment unit: for example, starting from the AC reverse axis of the positive current, for example, 0A after a time of 3.32ms, a negative instantaneous current of -1.4A after a time of 83μsec and a time of 4.15ms is first passed as a constant and stored in the database. When the circuit of the corresponding system experiences a sudden spark / leakage tracking phenomenon, for example, when the positive or negative current value is arbitrarily set to 15 to 20 times, the relevant personnel's PC, smartphone, tablet, etc. send an alert signal. When the value is greater than 20 times, the corresponding system's circuit is confirmed and automatically cut off.

[0345] Alternatively, the following implementation method can be adopted: send a warning to relevant personnel that the circuit has been automatically cut off due to leakage and tracking, and continue to send warnings until the relevant personnel confirm and reset, so as to ensure the safe restoration of the corresponding circuit and the uninterrupted operation or function.

[0346] The DESCON emergency system can also be implemented as follows: For example, starting from 0A after 3.32ms of positive current AC reverse axis, (4.15ms of negative instantaneous current -1.4A after 83μsec) + (4.98ms of negative current -0.8A) + (5.81ms of negative current -2.0A) + (6.64ms of negative current -1.7A) + (7.47ms of negative current -4.1A) / 5 = -2.0, that is, the above average current is -2.0. The pre-set average current, i.e., the instantaneous current -2.0A, is used as a constant denominator to detect sparking / tracking phenomena with a current ratio of 20 times or more.

[0347] The DESCON emergency system can, for example, detect the corresponding current multiplier by multiplying the current of 0A (e.g., 3.32ms) from any set positive current AC reverse axis. This is followed by the following negative instantaneous currents: -1.4A at 4.15ms (83μsec elapsed), -0.8A at 4.98ms, -2.0A at 5.81ms, -1.7A at 6.64ms, and -4.1A at 7.47ms. Finally, it uses the -4.1A 0.83ms before the occurrence of the sparking / tracking phenomenon (81.7A at 8.30ms elapsed, multiplied by 15-20 times) as a constant denominator.

[0348] The DESCON emergency system can also be implemented as follows: For example, starting from the positive current mentioned above, detect the first measured current of -1.4A after the negative current segment following the AC 0 reversal, which has an elapsed time of 3.32ms. Detect the current multiplier with -1.4 as the denominator, and use the average current of (measured current -1.4A... + measured current -4.1A after elapsed time of 7.47ms) / 5 with an elapsed time of 3.32ms as the denominator, which is -2.0, to detect the corresponding multiplier of each measured current A.

[0349] The implementation method is as follows: The first current after AC reversal, i.e. the current before leakage tracking, -4.3A, is used as the denominator for each measurement. For example, the measured currents are -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, and -3.5 / -4.3 = 0.81 times. The multiplier of the measured current is arbitrarily set to be less than 15 times in advance, which is considered normal.

[0350] The following implementation method can be adopted: take the current of 15.0 to 20 times or more of the measured current ratio as the leakage current, and issue a warning and automatically cut off according to the predetermined ratio.

[0351] For example, the following implementation method can be adopted: the current after 128.235ms -65.5A / -4.3A = a multiplier of 15.2 is determined as the current of leakage tracking phenomenon.

[0352] Upon making this determination, the corresponding circuit is automatically disconnected.

[0353] Automatic disconnection can also be performed when the current ratio for automatic disconnection is arbitrarily set in advance, for example, 21 times or more, which is 15 to 20 times or more.

[0354] Alternatively, the following implementation method can be adopted: use the average current before tracking after AC reversal as the denominator of each measured current, and use the measured current, for example (-4.3) + (-4.6) + (-4.6) + (-4.2) + (-3.5) / 5 = -3.5A, as a constant denominator. The measured currents are, 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, and -3.5 / -4.2 = 0.83 times. The multiplier of the measured current is arbitrarily set in advance to be below 15.0, which is considered normal.

[0355] The following implementation method can be adopted: the current multiplier, for example, arbitrarily set current of 15.0 to 20 times or more, is used as the leakage current, and warning and automatic cut-off are triggered according to the predetermined multiplier.

[0356] For example, the following implementation method can be adopted: the current after 128.235ms -65.5A / -4.2A = a multiplier of 15.4 is determined as the current of leakage tracking phenomenon.

[0357] If the above judgment is made, the corresponding circuit will be automatically cut off.

[0439] The elapsed time for the positive current A is 0.83ms to 2.49ms.

[0440] The positive current A measured over a time interval of 0.83 ms to 2.49 ms is called the multiplier of each measured current.

[0441] The current A is measured over a time interval of 83ms to 2.49ms.

[0442] Elapsed time 0.83ms: 2.1A, Elapsed time 1.66ms: 2.3A, Elapsed time 2.49ms: 1.0A.

[0443] The average current value is 1.8A during the 2.49ms elapsed before the zero-crossing point of the positive current (0A).

[0444] The following implementation method can be adopted: Based on the -1.4A elapsed for 4.15ms of the negative current A, for example, using the -1.4A elapsed for the first 4.15ms elapsed from the reverse axis 0A from positive to negative current as the denominator, calculate the current multiplier of the measured current at each measurement time to determine spark / leakage tracking. An implementation method based on a pre-set arbitrarily determined current multiplier for warning transmission and automatic disconnection can be adopted. Alternatively, the negative current in the alternating current can be the one that is opposite to the positive current.

[0445] The measured elapsed times of 4.15ms: -1.4A, 4.98ms: -0.8A, 5.81ms: -2.0A, 6.64ms: -1.7A, and 7.47ms: -4.1A are as follows.

[0446] The ratio of each current of negative current A over the time intervals of 4.15ms to 7.47ms to the average current of negative current A over the time intervals of 4.15ms: -1.4A to 7.47ms: -4.7A is -2.0A.

[0447] For example, the following implementation method can be used: Add the currents from -1.4A (4.15ms elapsed) to 4.1A (7.47ms elapsed) starting from the reverse axis from positive to negative current (0A). Divide the sum by 5, using the average current of -2.0A as the denominator. Determine spark / leakage tracking based on the average current multiplier. An implementation method based on a pre-set current multiplier for warning transmission and automatic disconnection can be used. Alternatively, the negative current in the alternating current direction can be used.

[0448] The measured elapsed time 4.15ms: (-1.4A + elapsed time 4.98ms: -0.8A + elapsed time 5.81ms: -2.0A + elapsed time 6.64ms: -1.7A + elapsed time 7.47ms: -4.1A) = average current -2.0A.

[0449] One implementation method is to detect the current multiplier by using the average current of the given currents (-1.4A, -0.8A, -2.0A, -1.7A, and -4.1A) as the denominator, which is -2.0. Another implementation method is to send warnings and automatically cut off the current based on a pre-set current multiplier. Alternatively, the current could be a negative current in the alternating current, opposite to the positive current.

[0450] The pre-set negative current A is arbitrarily set to be a current multiplier of 15 or more, for example, -4.1A after 7.47ms. Suppose -81.7A after 8.30ms is a current multiplier of 19.9. The current A is detected in units of elapsed time and the current multiplier is calculated.

[0451] For example, the following implementation method can be used: Starting from the reverse axis 0A from positive to negative current, detect current values ​​with a current multiplier of 15 or more. Using the current value of -81.7A after 8.3ms and the current value of -4.1A after 7.47ms as the denominator, determine sparking / tracking based on the measured current multiplier of each current. An implementation method can be adopted that sends an alert based on a pre-set arbitrarily set current multiplier and automatically cuts off when the multiplier exceeds 20. Alternatively, the negative current in the alternating current can be the opposite of the positive current.

[0452] The measured elapsed times are as follows: 4.15ms: -1.4A, 4.98ms: -0.8A, 5.81ms: -2.0A, 6.64ms: -1.7A, and 7.47ms: -4.1A.

[0453] The following implementation method can be adopted: using the aforementioned currents, such as -1.4A (S2), -2.0A (S3), and -4.1A (S3), as the denominator, to detect and determine the elapsed time of the negative current (8.30ms to 9.296ms) within a pre-set current multiplier of 15 times or more, the corresponding circuit for spark / leakage tracking in the system can be used. An implementation method that automatically cuts off the current at a pre-set current multiplier of 20 times or more can also be adopted. As an example of the current multiplier for each current, such as... Figure 23 As shown.

[0454] The DESCON emergency system can be implemented as follows: Current is detected using the aforementioned currents of -1.4A, 2.0A, and -4.1A as the denominator. If the current multiplier (in A) is greater than, for example, a pre-set multiple of 15, it is determined to be a spark leakage tracking fault. An implementation method can be adopted that sends an alert and automatically cuts off the circuit when the current multiplier exceeds 20.

[0455] The following implementation method can be adopted: Based on the elapsed time of the negative current A (127.82ms) and -4.3A, for example, the elapsed time of the first time (127.82ms) from the reverse axis 0A from the positive current to the negative current (0A) is used as the denominator, the current multiplier of the measured current at each measurement time is calculated to determine the spark / leakage tracking. An implementation method based on a pre-set arbitrarily set current multiplier for warning transmission and automatic disconnection can be adopted. Alternatively, the negative current in the alternating current can be the opposite of the positive current.

[0456] The measured elapsed times are as follows: 127.82ms: -4.3A, 127.903ms: -4.6A, 127.986ms: -4.6A, 128.069ms: -4.2A, and 128.152ms: -3.5A.

[0457] The ratio of each current for the negative current A over the elapsed time 127.82ms~128.152ms to the average current of -4.2A over the elapsed time 127.82ms: -4.3A~128.152ms: -3.5A.

[0458] The following implementation method can be adopted: For example, the currents from -4.3A (127.82ms elapsed) to -3.5A (128.152ms elapsed) on the reverse axis from positive to negative current can be added together. The sum is then divided by 5, with the average current of -4.2A as the denominator. Sparking / tracking is determined based on the average current multiplier. An implementation method based on a pre-set current multiplier for warning transmission and automatic disconnection can also be used. Alternatively, the negative current in the alternating current can be the opposite of the positive current.

[0459] The measured values ​​(elapsed time 128.82ms: -4.3A + elapsed time 127.903ms: -4.6A + elapsed time 127.986ms: -4.6A + elapsed time 128.069ms: -4.2A + elapsed time 128.152ms: -3.5A) = average current -4.3A.

[0460] One implementation method is to detect the current multiplier by using the average current of the given currents (-4.3A, -4.6A, -4.6A, -4.2A, and -3.5A) as the denominator, which is -4.2. Another implementation method is to send warnings and automatically cut off the current based on a pre-set current multiplier. Alternatively, the current could be a negative current in the alternating current, opposite to the positive current.

[0461] The detection of negative current A is arbitrarily set beforehand, which is a current multiplier of more than 15 times. For example, -4.1A after 7.47ms and -81.7A after 8.30ms are current multipliers of 19.9 times. The current A is detected in units of time and the current multiplier is calculated.

[0462] For example, the following implementation method can be used: starting from the reverse axis 0A from positive to negative current, detect current values ​​with a current multiplier of 15 or more. Use the current value of -4.1A at a time elapsed before the current value of -81.7A at a time elapsed for 8.3ms as the denominator, and determine sparking / tracking based on the measured current multiplier of each current. An implementation method can be adopted that sends an alert based on a pre-set arbitrarily set current multiplier and automatically cuts off the current when it exceeds 20 times. Alternatively, the negative current in the alternating current can be the opposite of the positive current.

[0463] The measured elapsed times are as follows: 128.82ms: -4.3A, 127.903ms: -4.6A, 127.986ms: -4.6A, 128.069ms: -4.2A, and 128.152ms: -3.5A.

[0464] The following implementation method can be adopted: A system circuit that detects and determines the elapsed time of negative current (9960ms~128.152mssc) at a pre-set current multiplier of 15 times or higher, using, for example, currents of -4.3A, -4.2A, and -3.5A as the denominator, to detect and determine the corresponding circuit for spark / leakage tracking at a pre-set current multiplier of 20 times or higher. An implementation method that automatically cuts off the current at a pre-set current multiplier of 20 times or higher can also be adopted. The current of each current... for example...

Sparking / tracking is determined based on the average current multiplier. The feature is also the following unit: it sends an alarm and automatically cuts off the current based on a pre-set current multiplier.

This can also be a negative current in AC current that is opposite to the positive current.

[0472] The detection system detects currents A at a pre-set current multiplier of 15 times or more before a positive current A is imminent. For example, 4.2A after 138.361ms and 81.9A after 138.444ms have a current multiplier of 19.5 times. The system detects each current A and calculates the current multiplier based on the elapsed time.

[0504] The feature is the following judgment unit: using the average current of -4.9A from the currents of -4.9A, -4.7A, -4.9A, -5.4A, and -4.7A as the denominator to detect the current multiplier; and the feature is the following unit: sending an alarm and automatically cutting off based on a pre-set current multiplier. This can also be a negative current in AC current that is opposite to the positive current.

[0505] The detection system detects a current A at a pre-set current multiplier of 15 times or more before a negative current A is imminent. For example, -4.9A after 167.162ms and -95.3A after 167.660ms have a current multiplier of 20.3 times. The system detects each current A and calculates the current multiplier based on the elapsed time.

[0506] For example, a feature of this unit is as follows: it detects a current value with a current multiplier of more than 15 times that of the reverse axis from positive to negative current (0A). Using the current value of -95.3A at a time elapsed (167.660ms) and the current value of -4.7A at a time elapsed (167.494ms) as the denominator, it determines sparking / tracking based on the measured current multiplier of each current. A feature of this unit is as follows: it sends an alarm based on a pre-set current multiplier and automatically cuts off the current when it exceeds 20 times. This could also be a negative current in alternating current that is the opposite of the positive current.

The system is characterized by the following control unit: sending an alarm and automatically cutting off when the multiple is greater than 20 times.

[0510] The feature is the following unit: based on the positive current A's elapsed time of 177.039ms (2.9A), 1) using, for example, the first elapsed time of 177.039ms (2.9A) from the reverse axis 0A from positive to negative current as the denominator, the current multiplier of the measured current at each measurement time is calculated to determine spark / leakage tracking. The feature is the following unit: based on a pre-set arbitrary current multiplier, an alarm is sent and automatic disconnection is performed.

[0512] Regarding the average current of 4.6A from 2.9A to 8.9A during the elapsed time of positive current A (177.039ms) to 177.454ms, we set it as the current multiplier for each elapsed time of S2 (177.039ms to 177.454ms).

[0513] For example, a feature of this unit is as follows: It adds up the currents from 2.9A to 8.9A over a time interval of 177.039ms (from positive to negative current at 0A), divides the sum by 6, and uses the average current of 4.6A as the denominator. It then uses the average current multiplier to determine sparking / tracking. A feature of this unit is that it sends an alarm and automatically cuts off the current based on a pre-set current multiplier. This could also be a negative current in AC current, opposite to the positive current.

[0514] The measured currents (177039ms elapsed: 2.9A + 177.122ms elapsed: 4.5A + 177.205ms elapsed: 3.9A + 177.288ms elapsed: 3.6A + 177.371ms elapsed: 3.6A + 177.454ms elapsed: 8.9A) / 6 = average current 4.6A.

[0516] The system detects a positive current A at a pre-set current multiplier of 15 or more, for example, 8.9A after 177.454ms and -81.7A after 177.454ms, which is a current multiplier of 7.6. The system detects each current A and calculates the current multiplier based on the elapsed time.

[0517] For example, a feature of this unit is as follows: it detects a current value with a current multiplier of more than 15 times that of the reverse axis from positive to negative current (0A). Using the current value of 67.2A at 177.537ms and the current value of 8.9A at 177.454ms as the denominator, it determines sparking / tracking based on the measured current multiplier of each current. A feature of this unit is as follows: it sends an alarm based on a pre-set current multiplier and automatically cuts off the current when it exceeds 20 times. This could also be a negative current in AC current that is the opposite of the positive current.

The system is characterized by the following control unit: sending an alarm and automatically cutting off when the multiple is more than 20 times.

[0521] The Joule heating procedure in the DESCON emergency system can be implemented as follows: Due to the loosening and gaps in the connecting metal parts of panels and circuits, the current value remains constant while the conductive area decreases, resulting in resistance heat generation and rise, thus triggering electro-Joule heating. To address this, temperature sensors are installed in the connecting metal parts and terminals of circuits such as low-voltage light and power distribution panels, main lines, light and power sub-distribution panels, and light and power control panels. Temperature sensors are also installed in each panel or in the connecting metal parts, sockets, and load facilities of main lines, wires, terminal equipment, etc., and in the remote panel of the distributor. If the allowable temperature of each cable is exceeded, an alarm signal is sent to relevant personnel when a pre-set alarm temperature is reached. When the alarm temperature has been at the predetermined temperature for a set time or has exceeded the pre-set warning temperature, the corresponding circuit is automatically cut off.

[0522] The DESCON emergency system can be implemented in the following ways: For any of the following devices or connecting equipment in a residence, apartment, office, commercial facility, hospital, hotel, research institute, exhibition hall, data center, logistics center, warehouse, factory, construction site, airport, ship, substation, power station, solar power generation, wind power generation, etc., including distribution cabinets, distribution panels, substations, control panels, terminal sockets, freezers, refrigerators, conveyors, welding machines, movable control panels, PCs, servers, network equipment, inspection operation devices, etc., such as fixed or temporary, movable, or mobile power cables, due to pressure from heavy objects, stretching, sharp-angle bending, etc., the conductive area for current flow is deformed, narrowed, bent, stretched, or compressed, resulting in wire breakage, reduction, or poor contact, generating Joule heat in the corresponding part. The system detects a temperature that is arbitrarily set in advance relative to the allowable temperature of the conductive material. For example, 1 to n Joule heat detection devices are installed on trunk lines, wiring, cables, etc., outside of the aforementioned reels. Joule heat detection devices are installed at any location where Joule heat may be generated in trunk lines, wiring, cables, etc. due to factors such as compression, bending, stretching, etc., resulting in a small conductive area or partial breakage. These devices are installed on various components of trunk lines, wiring, cables, etc., both on and outside the reels. When the abnormal temperature caused by the breakage or poor contact of the power cable of the aforementioned facilities increases and reaches a pre-set allowable temperature, an alarm temperature is triggered, and sound, numerical values, and images are sent to the relevant personnel's PCs, tablets, or smartphones for notification. In addition, the alarm sound will continue to play until the relevant personnel confirm and reset it to prevent the relevant personnel from missing the confirmation.

[0523] The DESCON emergency system can be summarized as follows: For the maximum permissible temperature of KIV and CV cables, pre-set alert and alarm temperatures, and send real-time warnings to relevant personnel's PCs, tablets, smartphones, etc., using sound, images, and numerical values. Automatically disconnect circuit breakers in corresponding facilities such as distribution panels, sub-distribution panels, control panels, main lines, and circuits. This can be applied to facilities such as those utilizing AI and IoT computer programs, logistics centers, large freezers and refrigerators, commercial facilities with high population density, airport terminals and hotels, lighting and elevators, data centers storing important data and research results, substations, and electric trains in transportation systems. When the corresponding facilities and electrical equipment of ships and other similar facilities and electrical equipment are shut down according to a predetermined program, in this system consisting of remote devices of various systems such as distribution panels, sub-distribution panels, control panels, main lines, circuits and circuit breakers, cloud servers and LANs, the remote devices of each system, cloud servers and LANs, through the emergency response protection professional program, send signals to the protection stop device through the remote devices of the corresponding distribution panels, sub-distribution panels and control panels. The batch or selected terminal devices of the control system have the function of shutting down according to a predetermined program. The above is a functional control unit for normal and safe stop, and it can also confirm the stop signal.

[0524] As an example of a Joule heat detection device configured in various panels, trunk lines, cables, and wiring of the DESCON emergency system, it can be described as follows.

[0525] For example, it can detect abnormal temperature rises caused by Joule heating due to broken wires or poor contact in the power cables of refrigerators, washing machines, and electrical products in offices, residences, factories, etc.

[0526] For example, it can detect abnormal temperature rises caused by Joule heating, such as broken power cables or poor contact, in movable control panels of factories, research institutes, data centers, servers, etc.

[0527] For example, abnormal temperature rises caused by Joule heating, such as broken power cables or poor contact, in the power cables of conveyors in logistics centers are detected.

[0528] For example, abnormal temperature rises caused by Joule heating due to broken power cables or poor contact in welding equipment at construction sites are detected.

[0529] For example, detecting abnormal temperature rises caused by Joule heating in the power cables of a building's electrical distribution cabinet due to broken wires or poor contact.

[0530] The DESCON emergency system can be implemented as follows: using the following structure, the set current value is connected, and each panel of each system, as well as electrical facilities, electrical equipment and terminal facilities, operate and stop as follows.

[0531] The main line of power supply, such as a CV cable, from the substation / distribution cabinet is connected to the lights and power panel. The CV cable is then securely connected from outside the panel to the terminal block of the main circuit breaker with bolts and screws to a predetermined tightening torque strength.

[0532] The KIV cables, which are tightly connected to the secondary side terminal blocks of the main circuit breaker by bolts and screws with a predetermined tightening torque strength, are also tightly connected to the primary side terminal blocks of each branch circuit breaker by bolts and screws with a predetermined tightening torque strength.

[0533] The wiring branches are connected from the secondary side terminals of each branch circuit breaker to the terminals of the distribution panel via KIV cables, or via magnetic switches, and then securely connected with bolts and screws to a predetermined tightening torque strength.

[0534] From the terminal blocks of the distribution panel, connections are made to the various load facilities via, for example, CV cables.

[0535] Regarding the DESCON emergency system, for currents energized by the structure of the aforementioned electrical facilities, Joule heating is generated due to loosening and gaps in the screws, bolts, and terminal connectors of the connecting metal parts of each panel, as described below. For example, temperature sensors are installed in each circuit of CV cables and KIV cables, and the detected temperature of the wiring or copper rods is input. For example, when a pre-set temperature is reached, it is determined that Joule heating has occurred in the connection part of the corresponding terminal, etc.

[0536] The main power supply line, such as a CV cable, from the substation / distribution cabinet is bolted and screwed to the primary side terminal block of the main circuit breaker of the light and power panel with a predetermined tightening torque strength. A temperature sensor is installed on the CV cable of the connection part, and the alarm temperature of the CV cable is monitored by a wire or copper rod temperature detector connected to the temperature sensor.

[0537] Temperature sensors are installed on the outside of the terminal block of the main circuit breaker, such as on the CV cable, and on the inside of the terminal block, such as on the KIV cable. Temperature detectors, such as wires or copper rods connected to the temperature sensors, are used to monitor the CV cable alarms and temperature.

[0538] Regarding the DESCON emergency system, in the following wires, for example...

[0539] The maximum operating temperature for IV-KIV core wires and insulation is 60 degrees Celsius.

[0540] The maximum operating temperature of VVF is 60 degrees Celsius, which is the allowable temperature of the core wire and insulation.

[0541] The maximum operating temperature of VCT is 60 degrees Celsius, which is the allowable temperature of the core wire and insulation.

[0542] For indoor use of HIV-resistant materials at 600V, the maximum allowable operating temperature for the core wire and insulation is 75 degrees Celsius.

[0543] For 600V indoor use, the maximum operating temperature of the core wire and insulation is 90 degrees Celsius.

[0544] The maximum operating temperature of MLFC is 90 degrees Celsius for the core wire and insulation.

[0545] Regarding the DESCON emergency system, for the IV-KIV maximum operating temperature of the core wire and insulation, which is 60 degrees Celsius, if a pre-set temperature of 55 degrees Celsius (5 degrees Celsius less than the maximum operating temperature of the core wire and insulation) is detected, it is used as an alert temperature. The system sends an audible warning to relevant personnel via PC, tablet, or smartphone, indicating information such as the customer's name, building name, facility name, location, and type of light and power source. For example, if a pre-set temperature of 60 degrees Celsius is detected as an alarm temperature, the system automatically cuts off the corresponding circuit. The system also sends an audible, numerical, and visual warning to relevant personnel via PC, tablet, or smartphone, indicating the customer's name, building name, facility name, location, and type of light and power source, and automatically cuts off circuit breakers in the corresponding facility's distribution panel, sub-distribution panel, control panel, main lines, and circuits. The following implementation method can be adopted: When the program controls and control terminal devices of the corresponding terminal facilities and electrical equipment are shut down through a predetermined program, for the distribution panel, sub-distribution panel, control panel, main line, circuit and circuit breaker, etc., through the remote devices of each system, cloud server and LAN, etc., the emergency response protection program is used to send a stop to the protection stop device through the remote devices of the corresponding distribution panel, sub-distribution panel and control panel, etc., so as to safely and reliably realize the stop function and the function of confirming the stop signal.

[0546] Alternatively, the following implementation method can be adopted: For the maximum operating temperature of the core wire and insulation of the aforementioned materials such as KIV, VVF, and VCT, which is 60 degrees Celsius, if the temperature exceeds a pre-set maximum operating temperature of 60 degrees Celsius, or for example, if it exceeds a pre-set 70 degrees Celsius for 30 minutes, Joule heating will be generated, indicating a danger. The corresponding circuit will be automatically cut off. At the same time, the system will send warnings to relevant personnel via PC, tablet, smartphone, etc., using sound, numerical values, images, etc., including the customer's name, building name, facility name, location, and type of light and power. When the program controls and control terminal devices of the corresponding terminal facilities and electrical equipment are shut down according to a predetermined program, for the distribution panel, sub-distribution panel, control panel, main line, circuit, and circuit breaker, etc., through remote devices of each system, cloud servers, and LANs, etc., using emergency response protection professional programs, the remote devices of the corresponding distribution panel, sub-distribution panel, and control panel send a stop signal to the protection stop device, which can safely and reliably realize the stop function and the function of confirming the stop signal.

[0547] For HIV indoor use, the maximum operating temperature of 600V is 75 degrees Celsius, and the allowable temperature of the core wire and insulation is 75 degrees Celsius. If a pre-set, arbitrarily set allowable temperature of 75 degrees Celsius is detected, it will be used as an alarm temperature. The alarm will be sent to relevant personnel via PC, tablet, smartphone, etc., using sound, numerical values, images, etc., with information such as customer name, building name, facility name, and location.

[0548] For HIV and other high-temperature applications, the maximum operating temperature of the core wire and insulation is 75 degrees Celsius. If the temperature exceeds a pre-set value of 75 degrees Celsius and reaches 76 degrees Celsius, an alarm current will be triggered. This alarm will be sent to relevant personnel via PC, tablet, smartphone, etc., using sound, numerical values, or images. The alarm will include the customer's name, building name, facility name, location, and type of light and power source. Alternatively, for example, the following implementation method can be adopted: If 30 minutes have passed at a pre-set temperature of 76 degrees Celsius, the temperature is judged to be dangerous due to the generation of Joule heat, and the corresponding circuit is automatically cut off as an alarm temperature. At the same time, warnings are sent to relevant personnel via PC, tablet, smartphone, etc., using sound, audio, numerical values, images, etc., with information such as customer name, building name, facility name, location, and type of light and power. When the program controls and terminal devices of the corresponding terminal facilities and electrical equipment are shut down according to a predetermined program, for the distribution panel, sub-distribution panel, control panel, main line, circuit and circuit breaker, etc., through remote devices of each system, cloud server and LAN, etc., using emergency response protection professional programs, the remote devices of the corresponding distribution panel, sub-distribution panel and control panel send a stop to the protection stop device to achieve a safe and reliable stop function, and also realize the function of confirming the stop signal.

[0549] The following implementation method can be adopted: For the maximum operating temperature of CV indoor 600V core wire and the allowable temperature of insulation of 90 degrees, if a pre-set maximum operating temperature of core wire and insulation of 90 degrees is detected, or if 30 minutes have passed at a pre-set 90 degrees, Joule heating is generated and it is judged as dangerous, which is used as an alarm temperature. The corresponding circuit is automatically cut off. The alarm is sent to relevant personnel through PC, tablet, smartphone, etc., in the form of sound, numerical value, image, etc., with the customer name, building name, facility name, location, and type of light and power. When the program control and control terminal equipment of the corresponding terminal facilities and electrical equipment are shut down through the predetermined program, for the distribution panel, sub-distribution panel, control panel, main line, circuit and circuit breaker, etc., through the remote devices of each system, cloud server and LAN, etc., using the emergency response protection professional program, the remote devices of the corresponding distribution panel, sub-distribution panel and control panel send a stop to the protection stop device to realize the function of safe and reliable stop and realize the function of confirming the stop signal.

[0550] The DESCON emergency system is as follows: it also sends sound, numerical, and image alerts to the PCs, tablets, and smartphones of relevant personnel; it sends sound, numerical, and image alerts to smartphones; it also sounds an alarm until the relevant personnel confirm and reset the system; and it sends multiple emails and rings the alarm continuously to prevent the relevant personnel from missing confirmation.

[0551] The DESCON emergency system can be implemented as follows: For the maximum permissible temperature of KIV cables and CV cables, pre-set alert and alarm temperatures, and send real-time warnings to relevant personnel's PCs, tablets, smartphones, etc., via sound, images, and numerical values. It automatically cuts off circuit breakers in corresponding facilities such as distribution panels, sub-distribution panels, control panels, main lines, and circuits. Alternatively, it can be used in applications such as the production and manufacturing of goods using AI and IoT computer programs, logistics centers, large freezers and refrigerators, commercial facilities with large crowds, airport terminals and hotels, data centers storing important data and research results, substations for infrastructure, and electric trains and ships in transportation systems. When the corresponding facilities and electrical equipment of ships and other similar entities are shut down through a predetermined program, the system, consisting of remote devices of various systems such as distribution panels, sub-distribution panels, control panels, main lines, circuits, and circuit breakers, cloud servers, and LANs, uses emergency response protection professional programs through the remote devices of each system, cloud servers, and LANs to send signals to the protection stop device. Batch or selected terminal devices of controls and other similar entities then perform the shutdown function through the predetermined program, thereby achieving the normal and safe stop function and enabling the confirmation of the stop signal.

[0552] Equations regarding the maximum permissible temperature for different types of wires, as well as alert temperature, alarm temperature, and automatic disconnection.

[0553] The relationship between the types, uses, and maximum permissible temperatures of electrical wires and alert temperatures, alarm temperatures, and automatic disconnection.

[0554] The Joule heating program in the DESCON emergency system can be implemented as follows: Using the allowable temperatures of cables and wires of different temperatures—for example, IV / KIV (60 degrees Celsius), VVF (60 degrees Celsius), VCT (60 degrees Celsius), HIV (75 degrees Celsius), CV (90 degrees Celsius), and MLFC (90 degrees Celsius)—as a reference, if, relative to a pre-set allowable temperature, such as a distribution panel, sub-distribution panel, junction box, connection equipment, terminal equipment, connecting facilities and equipment, terminals, electrical equipment / instruments, cables, and wires, the temperature exceeds the allowable temperature by, for example, +10 to 15 degrees Celsius for 15 minutes or exceeds the allowable temperature by 15 degrees Celsius, then an alarm temperature can be determined. In this case, an implementation method that automatically disconnects the corresponding cables, circuits, connection equipment, and terminals can be adopted.

[0555] The system also sends alerts via PCs, tablets, smartphones, etc., to relevant personnel using sound, audio, numerical, and visual means, including information such as customer name, building name, facility name, location, type of light and power source, alarm temperature, and automatic shutdown status, to prevent relevant personnel from missing confirmation.

[0556] The DESCON emergency system can be implemented in the following ways to detect and assess the hazards of situations such as: Joule heating causing connected metal parts, terminals, wires, and circuits to exceed permissible temperatures; burning and melting of covering materials; temperature rise of corresponding wires and circuits due to Joule heating; melting of the covering materials of corresponding cables, wires, and circuits; and the generation of sparks / short circuits / tracking phenomena.

[0557] For reference, existing thermally conductive circuit breakers have the following functions: the temperature of the corresponding circuit, screws, bolts and terminals of the connecting metal parts rises due to overcurrent value A and time, and the thermally conductive circuit breaker with protection function operates and cuts off according to the set temperature and time, and protects the corresponding circuit and connecting metal parts from electrical burnout by using the overcurrent protection function.

[0558] The electronic circuit breaker has the following functions: It pre-sets a safe allowable current value A to conduct the corresponding circuit based on a reference such as the allowable current value of the connecting metal parts (screws, bolts, terminals, etc.). If the set current value A is reached, the thermally conductive circuit breaker with protection function operates to cut off the circuit, protecting the corresponding circuit and connecting metal parts from electrical burnout through overcurrent protection. The aforementioned thermally conductive circuit breaker operates its protection function based on temperature rise. The electronic circuit breaker also operates its protection function when the allowable current value A is reached. Currently, existing technology does not have the function of detecting instantaneous spark leakage tracking phenomena, such as the leakage tracking phenomenon caused by a short circuit in the insulation material of the current anode / cathode wires for 1 second / 12000 or 83 μsec.

[0559] The DESCON emergency system is a system that uses a current meter (CT) to detect current A in the corresponding circuits, connecting metal parts, and terminals of electrical facilities. It converts a current of 83 μsec (a common multiple of the power frequency, such as 50 Hz and 60 Hz, for example, 1 second divided by 12000 times) into a voltage. For a real analog voltage, it uses an analog-to-digital converter (ADC), such as a microcontroller, to detect current leakage and tracking phenomena caused by sparks exceeding the allowable temperature of the insulation covering material of the anode / cathode wires due to Joule heating from the connecting metal parts (such as the circuits, screws, bolts, and terminals), cables, wires, and terminal load facilities. The system detects the instantaneous current of the aforementioned 83 μsec. The current, using a conventional current such as 83 μsec as the denominator, can send warnings via PCs, smartphones, tablets, etc., to relevant personnel at times greater than 15 times the conventional current, including information such as customer name, building name, facility name, location, type of light, and power source. At times greater than 20 times the conventional current, the system automatically cuts off the corresponding circuit, connecting metal parts, cables, wires, and terminal load facilities. This prevents major electrical burns and fires, such as the insulation material of wires melting due to Joule heating, short circuit sparks, and tracking, and has a significant effect on preventing personal injury accidents in social, economic, and family aspects.

[0560] For the screws, terminals, etc. of the connecting metal parts such as switchboards, distribution boards, control panels, and terminal load facilities mentioned above, looseness and gaps in circuits, etc., and for cables and wires, such as the pipe wiring buried in the floor, due to the passage of heavy objects, tensile forces at the connection parts, etc., the current-carrying area of the corresponding cables and wiring materials becomes narrower, and the current conducts at a constant allowable current value. Thus, if the conduction area of a predetermined circuit, cable, wire, etc. is insufficient, the thermal resistance increases proportionally to the current, and Joule heat is generated proportionally to the elapsed time. If the allowable temperature of each wire is exceeded, the insulating covering material of the electrical anode / cathode will melt and burn, resulting in a short circuit and spark in the corresponding circuit and wire.

[0561] <Joule Heat Detection Device in the DESCON Emergency System>

[0562] One to n Joule heat detection devices are arbitrarily set in the power cables of temporary, movable, mobile, etc. types, such as in switchboards, distribution boards, distribution panels, control panels, terminal sockets, freezers, refrigerators, conveyors, welding machines, movable control panels, PCs, servers, network devices, inspection operation devices, etc. in residences, apartments, offices, commercial facilities, hospitals, hotels, research institutes, exhibitions, exhibition halls, data centers, logistics centers, warehouses, factories, construction sites, etc.

[0563] Detect the temperature rise caused by the disconnection or poor contact of the power cable, and automatically cut off the corresponding circuit when an abnormal temperature is detected.

[0564] Send warnings to the PCs, tablets, smartphones, etc. of relevant personnel in real time in the form of sound, images, numerical values, etc.

[0565] The system for Joule heat detection in the DESCON emergency system can adopt the following implementation method: Due to looseness and gaps in the connecting metal parts of the panel and circuits, etc., the current value remains constant while the conduction area decreases, resulting in the generation and increase of resistive heat, causing electrical Joule heat. Temperature sensors are set for each circuit of the connecting metal parts and terminals, etc. in the distribution boards for low-voltage lights and power, main lines, distribution boards for lights and power, control panels for lights and power, etc. Temperature sensors are set near the connecting metal parts, sockets, and load facilities, etc. of each panel or main line, wire, terminal equipment, etc. Temperature sensors for each circuit are set in the distributor and remote panel. If the allowable temperature of each cable is exceeded, when the warning temperature set arbitrarily in advance is reached, a warning signal is sent to relevant personnel for warning. When the warning temperature has passed the set time at the predetermined temperature or exceeds the arbitrarily set warning temperature, the corresponding circuit is automatically cut off.

[0566] Regarding high-voltage and low-voltage distribution panels, main lines, distribution boards, control panels, terminal facilities, electrical equipment / machinery, etc. (sometimes referred to as "panels" in this manual) of substation facilities, such as primary side wiring, screws, bolts, terminal connectors, and wiring of connecting metal parts, the wiring expands due to temperature rise as current flows through it, and contracts due to temperature drop after a power outage. The screws, bolts, terminals, etc., of the corresponding connecting metal parts... The phenomena of expansion when the wire is energized and contraction when the power is off are proportional to time and the number of years. Due to loosening and gaps in the wiring and other parts connected to the screws, bolts and terminals, poor connection of wiring and connecting metal parts, the conductive area of ​​electrical materials / connecting devices that conduct current is reduced to a predetermined size. Since the current value is constant, the contact conductive area is reduced, which causes the temperature of the thermal resistance value to rise, generating Joule heating. The temperature rises, and the connecting metal parts and wiring become high temperature. Sometimes, it exceeds the allowable temperature of the insulation covering materials of each cable and wiring, resulting in burnout and electrical fire accidents.

[0567] Regarding the maximum permissible temperature of different types of cables and wires, temperatures such as warning temperatures, alarm temperatures, and automatic shut-off temperatures can be preset to address Joule heating.

[0568] The DESCON emergency system is as follows: For the aforementioned cable types, such as "KIV cable maximum allowable temperature 60 degrees Celsius" inside the panel and "CV cable maximum allowable temperature 90 degrees Celsius" outside the panel, "one to N temperature sensors" are installed on each cable. Pre-set temperature sensors are used to detect situations where, for example, loose screws, bolts, and terminals in the KIV cable cause poor wiring connections and reduced current conduction area, resulting in Joule heating. This causes the cable temperature to rise and the insulation material to burn. Before this occurs, the system detects situations where the maximum allowable temperature of the KIV cable is pre-set. The system allows a minimum allowable temperature of 60 degrees Celsius, or can pre-set a "safe allowable temperature of 60 degrees Celsius" for the corresponding cable as an "alert temperature" to send a warning. If the "alarm temperature" exceeds a pre-set value of "maximum allowable temperature + 5 degrees" (e.g., 65°C) and reaches 66°C, it is considered an "alarm current." This triggers a warning to relevant personnel via PC, tablet, or smartphone using sound, numerical values, and images. The warning may include information such as the customer's name, building name, facility name, location, and type of light and power source. Furthermore, if the temperature (e.g., 65 degrees Celsius) remains above 65 degrees Celsius for more than one minute, it is considered an "alarm temperature" and the corresponding circuit is automatically cut off. This triggers a warning via sound, numerical values, and images to relevant personnel's PCs, tablets, or smartphones, including information such as the customer's name, building name, facility name, location, type and capacity of light and power source, electrical facilities at system terminals, and load facility names. An alarm also sounds until the relevant personnel confirm and reset the setting to prevent missed confirmation.

[0569] The DESCON emergency system can be summarized as follows: For the maximum permissible temperature of KIV and CV cables, pre-set alert and alarm temperatures, and send real-time warnings to relevant personnel's PCs, tablets, and smartphones via sound, images, and numerical values. Automatically disconnect circuit breakers in the corresponding facilities, such as distribution panels, sub-distribution panels, control panels, main lines, and circuits. Alternatively, it can be used in applications such as the production and distribution of goods using AI and IoT computer programs, logistics centers, large freezers and refrigerators, commercial facilities with high population density, airport terminals and hotels, lighting and elevators, data centers storing important data and research results, and infrastructure. When various facilities and electrical equipment in substations, electric trains, and ships of transportation institutions are shut down according to a predetermined program, the system, composed of remote devices of various systems such as distribution panels, sub-distribution panels, control panels, main lines, circuits, and circuit breakers, cloud servers, and LANs, uses an emergency response protection program to send signals to the protection stop device via the remote devices of each system, cloud server, and LAN. The batch or selected terminal devices of the control system have the function of shutting down according to a predetermined program. An implementation method with normal safe stop function and stop signal confirmation function can be adopted.

[0570] The maximum permissible Joule heating program for any type of wire, as well as the maximum permissible temperature and time, and the equations for alerting the temperature, alarming the temperature, and automatically cutting off the circuit using the Joule heating program.

[0571] In the rated current procedure of the DESCON emergency system, a current meter CT, which detects current A in the corresponding circuits, connecting metal parts, and terminals of electrical facilities, converts the current in 83μsec (e.g., a common multiple of power frequencies such as 50Hz and 60Hz, divided by 12000 times per second) into voltage. This analog-to-digital conversion is performed on the actual analog voltage. For main lines, lights, power distribution panels, junction boxes, branch lines, control panels, distributors, wiring, terminal facilities, electrical equipment, and machinery, the system considers the types, processes, quantities, loads, and processes of products or goods manufactured and researched by factories or research institutes, and the week, month, and season of activities, goods, items, banquet halls, and tenants handled by shops, data centers, logistics centers, warehouses, large exhibition halls, hotels, and terminals. The current values ​​of the aforementioned distribution panels and trunk lines for various businesses such as year-end and new year operations, electric trains, cars, ships, and airplanes as mobile tools, and electrical facilities for renewable energy sources such as solar, wind, and ocean currents, as well as distribution panels / circuit breakers, junction boxes, branch trunk control panels, distributors, wiring, terminal facilities, electrical equipment, and machinery, etc., installed in the aforementioned panels are monitored in real time by current meters (CTs). The allowable current value based on the current value of the aforementioned wiring size, etc., is detected based on factors such as the purpose of the aforementioned buildings, the manufacture or use of products, and the operating conditions of load facilities and electrical equipment, etc., to measure the current value energized in the aforementioned wiring and connecting metal parts, etc. Regarding the safe protection operating time of circuit breakers with different current values ​​determined according to the different sizes of the aforementioned trunk lines, wiring, circuits, and terminals, for example, when the rated current value is 30A, the protection disconnection operating time of the corresponding circuit breaker that can be set to 1.25 times the rated current value, i.e., 37.5A, is 60 minutes or less.

[0572] The DESCON emergency system can be implemented as follows: If the detected current value of a 30A circuit breaker is, for example, 31A, the corresponding circuit breaker's operating time is within 73 minutes. Regarding the pre-set operating time, for example, if the warning coefficient is set to 0.7, then the warning operating time = (73 minutes × pre-set warning coefficient 0.7) = 51.10 minutes. Automatic disconnection occurs after the 31A current's automatic disconnection operating time = (73 minutes × 0.9) = 65.7 minutes. For example, the upper limit of the rated current of 30A allows the current to be 2.0 times the rated current, i.e., 30A × 2.0. When the current is 60A, the circuit breaker's operating time is 2.0 minutes. If the DESCON emergency system detects, for example, an overcurrent of 60A, then after a pre-set warning coefficient of 0.7 = 2 minutes × 0.7 = 1.4 minutes after the detection, it will send warnings via sound, audio, numerical values, and images to relevant personnel's PCs, smartphones, tablets, etc., including information such as customer name, building name, facility name, location, and type of light and power. Regarding the pre-set automatic disconnection coefficient, since, for example, 2 minutes × 0.9 = 1.8 minutes, the warning disconnection time is determined to be 1.8 minutes.

[0573] In addition, the DESCON emergency system is as follows: it sends alerts to relevant personnel's PCs, smartphones, tablets, etc., indicating that circuit breakers and load facilities such as distribution panels, sub-distribution panels, control panels, main lines and circuits have been automatically disconnected, and continues to send alerts until the relevant personnel confirm the alert has been sent and reset.

[0574] The DESCON emergency system can be implemented as follows: It automatically shuts down system facilities and electrical equipment that would not be affected even if the electrical equipment itself were automatically disconnected. However, it excludes critical facilities and electrical equipment such as goods manufacturing and logistics centers using AI and IoT computer programs, large freezers and refrigerators, commercial facilities with high population density, lighting and elevators in airport terminals and hotels, data centers storing important data and research results, substations, and electric trains and ships in transportation systems. These are treated as non-automatically disconnectable items and are shut down through a predetermined program, thereby achieving safe and unimpeded automatic disconnection of the corresponding facilities. The system, consisting of remote devices of various systems such as distribution panels, sub-distribution panels, control panels, main lines, circuits, and circuit breakers, cloud servers, and LANs, uses emergency response protection programs through program controls of corresponding terminal facilities and electrical equipment. These remote devices transmit signals to the protection stop device. The system has the function of safely and normally shutting down the stop function control unit and batches or selected terminal devices using a predetermined program, and it also has the function of safely and normally controlling the stop function and confirming the stop signal.

[0575] The DESCON emergency system can be implemented using the following functions: To protect the safety of electrical facilities, a database is created showing the relationship between rated current, current value, and operating time. It detects whether the conducting current value of the circuit breakers installed in the control panel exceeds the rated allowable current value, and determines whether it is appropriately below the rated allowable current value. If it exceeds the rated allowable current value, the system determines within a few minutes to disconnect the corresponding circuit breaker based on the amount of current exceeding the limit (A). If the limit is exceeded, an audible alert is sent to relevant personnel's PCs, tablets, smartphones, etc., including information such as customer name, building name, facility name, location, and type of light and power source. For the corresponding facility's distribution panels, sub-distribution panels, control panels, and main circuits, remote devices of each system, cloud servers, and LANs are used to send stop signals to the protection stop device via emergency response protection programs, ensuring a safe and reliable stop and confirmation of the stop.

[0576] The DESCON emergency system can be implemented as follows: Regarding overcurrent relative to the rated current of each wire, the allowable current is 1.25 times the rated current, and the circuit breaker operating time for an overcurrent of 1.25 times the allowable current is less than 60 minutes. The current detected by the overcurrent is calculated using a pre-set warning sending coefficient for any time, and warnings are sent to relevant personnel's PCs, smartphones, tablets, etc., with information such as customer name, building name, facility name, location, and type of light and power. An automatic disconnection coefficient is pre-set for the corresponding wire to automatically disconnect the corresponding wire.

[0577] The relationship between the rated allowable current value of 31A and the rated current value of 1.25 times or more than the pre-set rated current value of 30A is as follows.

[0578] The DESCON emergency system can be implemented as follows: Regarding overcurrent relative to the rated current of each wire, the allowable current is 1.25 times the rated current, the operating time of the protective circuit breaker is, for example, 60 minutes for overcurrents below 30A, and the operating time of the circuit breaker for overcurrents of 2.0 times the allowable current is 6 minutes or less. The operating time is calculated using a pre-set alarm sending coefficient based on the detection current of the overcurrent detection. Alarms are sent to relevant personnel's PCs, smartphones, tablets, etc., using sound, etc., such as customer name, building name, facility name, location, and type of light and power. The corresponding wire is automatically cut off under the detection current of the pre-set automatic disconnection coefficient.

[0579] Electrical facilities such as distribution panels, main lines, sub-distribution panels, connecting metal parts, circuits and terminals, branch lines, wiring boxes, control panels, cabling, terminal load facilities / electrical equipment, wiring, terminal instruments, etc.; the types, processes, quantities, loads, and technologies of products or goods produced or researched by companies such as headquarters, factories, research institutes, shops, data centers, logistics centers, warehouses, large exhibition halls, hotels, and airport terminals; and the operation of corresponding facilities during peak hours such as week, month, season, year-end, and year-end, for events, goods, items, banquet halls, and tenants handled by shops, data centers, logistics centers, warehouses, large exhibition halls, hotels, and airport terminals, including activities, goods, items, banquet halls, and tenants. Therefore, the operation of distribution panels is high during busy periods, thus affecting the operation of these facilities. In main / branch trunk lines, distribution panels, control panels, terminal load facilities, electrical equipment, and terminal devices, for example, for wires rated at 30A to 2000A, the current of each terminal load facility, electrical equipment facility, and terminal load device, as well as load facilities exceeding the rated current capacity of each wire, such as branch trunk lines and power supply drums for engineering distribution panels at construction sites, and terminal machinery, electrical equipment facilities, and power tools, is below the predetermined rated current. However, when the electrical capacity or number of each terminal load machinery, electrical equipment facility, and power tool connected to the corresponding panel or power supply drum exceeds the rated current of the connecting metal parts, terminals, wiring circuits, trunk lines, and wiring of the corresponding panel, no overcurrent will occur. On the other hand, if the electrical capacity or number of terminal load machinery, electrical equipment facilities, and power tools connected to the corresponding panel or power supply drum exceeds the rated current due to usage conditions or the system's operating rate exceeds the rated current, overcurrent exceeding the rated current may occur in the corresponding system's panels, trunk lines, and circuits due to the power consumption of the electrical facilities.

[0580] Thermally activated circuit breakers installed in various panels will trip and disconnect the corresponding circuit after a predetermined time. However, the current in the corresponding circuit may exceed the rated current, resulting in an overcurrent. Examples of electrical burnouts / fires caused by overcurrent include temporary / existing power supplies at construction sites, logistics centers, and warehouses. When multiple circuit breakers, trunk lines, circuits, wires, and connecting metal parts in various panels are used simultaneously, and the amount of electricity used exceeds the rated current capacity, the thermal resistance increases when the current capacity exceeds the predetermined diameter and conduction area of ​​the wires, etc. This causes the temperature of the corresponding wires, trunk lines, cables, and connecting metal parts to rise, generating Joule heating. For example, the electrical insulation covering material may melt, and the temperature of the connecting metal parts may increase. There are instances where electrical burnouts and fires occur due to overcurrent caused by an increase in the number of terminal load facilities and electrical equipment facilities, the power consumption capacity, and the above-predetermined large-scale utilization.

[0581] The DESCON emergency system can be implemented as follows: If a current value of 31A is detected that causes a 30A circuit breaker to conduct, the corresponding circuit breaker's operating time is within 73 minutes. For a pre-set operating time, for example, if the warning coefficient is set to 0.7, then when the warning operating time = (73 minutes × pre-set warning coefficient 0.7) = 51.10 minutes, an overcurrent warning is sent to relevant personnel's PCs, smartphones, tablets, etc. Alternatively, an implementation method can be adopted where the automatic disconnection occurs when the 31A current's automatic disconnection operating time = (73 minutes × pre-set warning coefficient 0.9) = 65.7 minutes. For example, the following implementation method can also be adopted: the upper limit of the rated current of 30A is allowed to be 2.0 times the rated current, that is, 30A×2.0 times, which is 60A. The circuit breaker operating time is 2.0 minutes. As mentioned above, if an overcurrent of 60A is detected, it is used as an arbitrarily set alarm overcurrent. According to the alarm coefficient of 0.7, an alarm is sent to the relevant personnel's PC, smartphone, tablet, etc. after 2 minutes×0.7=1.4 minutes after the detection. Alternatively, an implementation method can be adopted that automatically cuts off the circuit after 1.8 minutes of the alarm cutoff time according to a pre-set alarm cutoff coefficient, such as a cutoff coefficient of 0.9, which is 2 minutes×0.9=1.8 minutes.

[0582] The DESCON emergency system can be implemented as follows: send alerts to relevant personnel's PCs, smartphones, tablets, etc. In cases where circuit breakers and load facilities such as distribution panels, sub-distribution panels, control panels, main lines and circuits have been automatically disconnected, send alerts via sound, such as the customer's name, building name, facility name, location, and type of light and power, continuously until the relevant personnel confirm and reset the alert.

[0583] The DESCON emergency system can be implemented as follows: It automatically disconnects system facilities and electrical equipment that are unaffected by automatic shutdown, such as those used in the production and distribution of goods using AI and IoT computer programs, logistics centers, large freezers and refrigerators, commercial facilities with large crowds, airport terminals and hotels, data centers storing important data and research results, infrastructure substations, and various facilities and electrical equipment in transportation systems such as electric trains and ships. This is achieved through the use of program controls and terminal equipment for these facilities and electrical equipment. When the system is shut down according to a predetermined procedure, the remote devices of each system, such as distribution panels, sub-distribution panels, control panels, main lines, circuits, and circuit breakers, as well as cloud servers and LANs, use emergency response protection programs to send signals to the protection stop device through the remote devices of each system, cloud servers, and LANs. This system has the function of stopping normally and safely. It can be implemented in a way that allows shutdown of batch or selected terminal devices through a predetermined procedure, or in an implementation that has both the function of stopping normally and safely and the function of confirming the stop signal.

[0584] The DESCON emergency system can be implemented in the following ways: To protect the safety of electrical facilities, a database of the relationship between current values ​​and operating time is created. It detects whether the conducting current value of circuit breakers installed in the panel is below or exceeds the rated allowable current value according to JIS standards, determining whether it is appropriately below the rated allowable current value. If it exceeds the rated allowable current value, it determines the circuit breaker to cut off the corresponding circuit within a few minutes based on the number of A of the excess current. Alternatively, it can be implemented with the following functions: Upon disconnection, it sends alerts to relevant personnel's PCs, tablets, smartphones, etc., using information such as customer name, building name, facility name, location, and type of light and power source. It sends alerts in real time using sound, images, and numerical values. Automatic disconnection is performed using emergency response protection programs via remote devices of various systems, cloud servers, and LANs. The remote devices of the corresponding distribution panels, sub-distribution panels, and control panels send a stop signal to the protection stop device, ensuring a safe and reliable stop, and confirming the stop.

[0585] The DESCON emergency system can be implemented as follows: When energizing a circuit breaker due to overcurrent exceeding its rated current value, and when the conduction area of ​​each wire is fixed but a current exceeding the predetermined rated current is applied, the thermal resistance increases due to the overcurrent exceeding 100% of the conduction area, generating Joule heating. For example, the allowable temperature of different wires such as IV / KIV (60 degrees Celsius), VVF (60 degrees Celsius), VCT (60 degrees Celsius), HIV (75 degrees Celsius), CV (90 degrees Celsius), and MLFC (90 degrees Celsius) exceeds the allowable temperature of the current applied, for example, below the current value required for the circuit breaker to thermally operate, or below the current value required for the electronic circuit breaker to operate, the circuit breaker does not operate to disconnect, generating Joule heating, etc., exceeding the allowable temperature of the wire. If the insulation material melts, causing wire burnout / fire, etc., the maximum allowable temperature of the CV cable is 90 degrees Celsius. The detection temperature when the power is connected is stored in the corresponding terminal block, such as R phase 33.2 degrees Celsius, S phase 33.3 degrees Celsius, T phase 32.9 degrees Celsius. The maximum allowable temperature of 90 degrees Celsius is set as the warning temperature in advance. If the alarm temperature is set to 95 degrees Celsius (pre-set arbitrarily), such as the maximum allowable temperature + 5 degrees Celsius, or if the temperature of 95 degrees Celsius is maintained for more than 1 minute and rises above 95 degrees Celsius, it is considered an alarm temperature. The corresponding circuit is automatically cut off, and the alarm is sent to the relevant personnel's PC, tablet, or smartphone with sound, numerical values, images, etc., such as customer name, building name, facility name, location, and type of light and power. In addition, the alarm bell rings continuously until the relevant personnel confirm and reset it to prevent the relevant personnel from missing the confirmation.

[0586] The DESCON emergency system can be implemented as follows: Due to overcurrent, for example, based on the allowable temperatures of cables and wires with different allowable temperatures (e.g., IV / KIV 60°C, VVF 60°C, VCT 60°C, HIV 75°C, CV 90°C, MLFC 90°C), if the allowable temperature of distribution panels, junction boxes, connection devices, terminal equipment, connecting facilities / equipment, cables, and wires exceeds the allowable temperature—for example, exceeding any +10 to 15°C for any 5 minutes, or exceeding the allowable temperature by 15°C—it is determined to be an alarm temperature. An implementation that automatically disconnects the corresponding cables, circuits, connection devices, and terminals in this situation can be adopted. Alternatively, the following implementation method can be used: send alerts to relevant personnel's PCs, tablets, and smartphones with sound, numerical values, and images, such as customer name, building name, facility name, location, type of light and power, sound, etc., alarm temperature, and automatic shutdown status. In addition, send emails continuously while the alarm rings continuously until the relevant personnel confirm and reset, to prevent the relevant personnel from missing confirmation.

[0587] The DESCON emergency system can be implemented as follows: For example, if Joule heating is generated and exceeds the allowable temperature of connecting metal parts, terminals, wires, and circuits, short circuits may occur in the corresponding wires and circuits due to burning and melting of the covering material, resulting in sparking and tracking phenomena. If the temperature of the corresponding wires rises due to Joule heating and exceeds the allowable temperature of each wire and reaches a pre-set temperature before the insulation covering material melts, an alert will be sent to the relevant personnel's PCs, smartphones, tablets, etc., with information such as customer name, building name, facility name, location, and type of light and power. In addition, if the temperature rises further to a pre-set temperature, automatic disconnection will be performed. The system detects and judges sparking / tracking phenomena caused by Joule heating, such as melting or burning of the covering material due to the resistance of the corresponding cables, wires, and circuits.

[0588] When the temperature of the corresponding connecting metal parts, terminals, circuits, and wires rises above the allowable temperature specified for each type of wire, the insulation covering material that prevents short circuits and sparks from the wires melts due to the corresponding Joule heating. Sparks, leakage, and tracking are generated at the corresponding molten parts, resulting in electrical burns, which is the main cause of electrical fire accidents.

[0589] Existing thermal circuit breakers are devices in which the temperature of the corresponding circuit, screws, bolts, and terminals of the connecting metal parts rises according to the overcurrent value A and the elapsed time. The thermal circuit breaker with protection function cuts off the circuit according to the set temperature and time, and uses the overcurrent protection function to protect the corresponding circuit and connecting metal parts from electrical burnout.

[0590] The electronic circuit breaker has the following functions: it sets a safe allowable current value A to make the corresponding circuit conduct based on the allowable current value of the connecting metal parts such as screws, bolts and terminals. If the set current value A is reached, the circuit breaker with protection function will operate to cut off the circuit. It protects the corresponding circuit and connecting metal parts from electrical burnout by using the overcurrent protection function. The above-mentioned thermally conductive circuit breaker operates the protection function of the corresponding circuit breaker based on the temperature rise, and the electronic circuit breaker also operates the protection function of the corresponding circuit breaker when the allowable current value A is reached.

[0591] The DESCON emergency system is as follows: A current meter (CT) that detects current in the corresponding circuits, connecting metal parts, and terminals of electrical facilities due to overcurrent, etc., converts current into voltage at various frequencies such as 50Hz and 60Hz, for example, at 12,000 times per second for 83μsec. For a realistic analog voltage, an analog-to-digital converter (ADC), such as a microcontroller, is used to detect short circuits and leakage caused by thermal action of the circuits, screws, bolts, and terminals, connecting metal parts, cables, wires, and terminal load facilities, etc., due to electrothermal resistance and Joule heating caused by current below the allowable current of electronic circuit breakers not operating, leading to deterioration or melting of wire covering materials. For example, within 83μsec... For example, it can detect currents of 15 to 80 times the normal current, or detect the allowable temperature of corresponding circuit wires, and send warnings to relevant personnel's PCs, smartphones, tablets, etc. with sound, numerical values, images, etc., such as customer name, building name, facility name, location, type of light and power. For example, when the current is 20 times or more than the normal current with a pre-set arbitrarily set denominator, it can automatically cut off the corresponding circuit, connect metal cables and wires, control IOTB and terminal load facilities, etc. For example, it can prevent major electrical burns and electrical fires caused by the melting of wire insulation covering materials due to Joule heating, short circuit sparks, and leakage tracking. It has a significant effect on preventing personal injury accidents in social, economic and family aspects.
