[0016] The digital emergency electric safety control system of the present invention, i.e., the DESCON emergency system, comprises a power supply, an instantaneous current value detection device, an instantaneous current value determination device, a first alarm notification information output means, a means for determining whether the power supply can be automatically shut off, a first power supply cutoff device, a second power supply cutoff device, an internal temperature information acquisition means, an electric circuit temperature information acquisition means, an internal temperature monitoring means, an electric circuit temperature information monitoring means, a second alarm notification information output means, and a third alarm notification information output means. Hereinafter, in this specification and drawings, the "digital emergency electric safety control system" may be referred to as the "DESCON emergency system" or "DESCON." The power supply device comprises a power supply side electric circuit, which is an electric circuit from the power source side, and multiple load side electric circuits, which are electric circuits branching from the power supply side electric circuit and heading to multiple loads, electrically connected within the housing. A first electric device is mounted in a power supply side electric circuit within the housing, and second electric devices are mounted in each of a plurality of load side electric circuits within the housing. The first electric device mounted in the power supply side electric circuit and the plurality of second electric devices mounted in each of the plurality of load side electric circuits are both disposed within the housing.

[0017] Examples of such power devices include various types of substation equipment, distribution boards, switchboards, lighting panels, power panels, control panels, remote control device panels, and junction boxes for branch wiring connections of extension cords or wiring between distribution boards or switchboards and devices / appliances.The first electrical device is disposed within the housing constituting the above-mentioned power device and electrically connects the power supply side electric circuit from the power source side to the load side electric circuit toward the load, and examples thereof include a main breaker and an earth leakage breaker.The multiple second electrical devices are circuit switches of a type different from the above-mentioned main breaker and earth leakage breaker, and examples thereof include a magnetic switch, a power relay, and a solid-state relay. Examples of loads connected to the load-side electric circuits include electric power and electrical devices and equipment that operate on power, such as motors, elevators, air conditioning equipment, ventilation equipment, lighting equipment, refrigerated / freezer cases, refrigerators / freezers, measuring instruments, computer equipment, surveillance cameras, medical equipment, and communication devices. These include electric power and electrical devices and equipment installed and used both inside and outside buildings, and electric power and electrical devices and communication devices and equipment installed and used in vehicles and transportation such as trains, cars, airplanes, and ships, as well as electrical outlets to which these devices are connected. These loads are connected to the ends of the respective load-side electric circuits. An instantaneous current detection device is connected to the electric circuits and detects the instantaneous AC or DC current flowing through the electric circuits at an instant. For example, the instantaneous current detection device is connected to the load-side electric circuit and detects the instantaneous AC or DC current flowing through the load-side electric circuit at an instantaneous time.

[0018] The instantaneous current value detection device may be a current sensor using an instrument current transformer called a CT (Current Transformer), or a DC instantaneous current meter using a Hall element as shown in FIG. 17.

[0019] The unit of time for instantaneous time detection is, for example, 1 / 12000 seconds = 83 microseconds, and can be set arbitrarily between 1 / 50,000 seconds (= 20 μsec) and 1 / 100,000 seconds (= 10 μsec). Within this range, the microsecond can also be set in proportion to the performance of the computer (PC) that makes up the DESCON emergency system.

[0020] Setting the instantaneous time unit for instantaneous time detection to microseconds between 1 / 50,000 seconds (=20 μsec) and 1 / 100,000 seconds (=10 μsec) is advantageous in that it enables the risk of a tracking phenomenon occurring to be detected earlier and necessary measures, such as cutting off the power supply, to be taken before the tracking phenomenon occurs.

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

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

[0023] Furthermore, for example, an instantaneous current value in a range exceeding 17 times and up to 22 times the normal current value in the detected electrical circuit is determined to be within the power supply cut-off range and alarm issuance range described below.

[0024] When the instantaneous current value determination device determines that the instantaneous current value is within a predetermined alarm range, the first alarm notification information output means performs a process of outputting alarm notification information, together with information identifying the power device associated with the housing, to an administrator terminal used by the administrator managing the power device and to a staff terminal owned by a staff member in charge of managing the power device.

[0025] The manager terminal can be configured as a personal computer or the like equipped with an image information display means such as a monitor. The staff terminal can be configured as a mobile terminal such as a smartphone onto which an application for operating the system of the present invention has been downloaded. The manager terminal and staff terminal are connected via a communication network such as the Internet or a dedicated line so as to be able to exchange information with a computer system consisting of a server computer or the like that constitutes the digital emergency electric safety control system of the present invention, i.e., the DESCON emergency system.

[0026] When the instantaneous current value determination device determines that the instantaneous current value is within a predetermined power supply cutoff range, the power supply automatic cutoff possibility determination means performs a process to determine whether the load to which the current of the determined instantaneous current value is supplied is a load to which the power supply can be automatically cut off.

[0027] The first power supply cutoff device performs processing to automatically cut off the power supply to the load for which it has been determined by the automatic power supply cutoff possibility determining means that automatic power supply cutoff is possible.

[0028] When the automatic power supply cutoff capability determination means determines that the automatic power supply cutoff is not possible, the second power supply cutoff device cuts off the power supply to the load device control device that controls the load that has been determined to be unable to automatically cut off the power supply, and then performs processing to automatically cut off the power supply to the load.

[0029] The enclosure internal temperature information acquisition means constantly detects the temperature inside the enclosure and performs a process of outputting enclosure internal temperature information, which is information about the detected temperature inside the enclosure, together with information identifying the power device associated with the enclosure, as digital information.The electric circuit temperature information acquisition means, which is composed of a digital temperature sensor, a digital thermometer, etc., constantly detects the temperature of the electric circuit and performs a process of outputting electric circuit temperature information, which is information about the detected temperature of the electric circuit, together with information identifying the electric circuit whose temperature is detected, as digital information.The enclosure internal temperature monitoring means performs a process of comparing the temperature inside the enclosure acquired by the enclosure internal temperature information acquisition means with a preset enclosure internal monitoring temperature.The electric circuit temperature monitoring means performs a process of comparing the temperature of the electric circuit acquired by the electric circuit temperature information acquisition means with a preset electric circuit monitoring temperature. The second alarm notification information output means performs processing to output alarm notification information to the manager terminal and the person in charge terminal when the internal enclosure temperature monitoring means determines that the temperature inside the enclosure acquired by the internal enclosure temperature information acquisition means has exceeded the internal enclosure monitoring temperature. The third alarm notification information output means performs processing to output alarm notification information to the manager terminal and the person in charge terminal when the load side electric circuit temperature monitoring means determines that the temperature of the electric circuit acquired by the electric circuit temperature information acquisition means has exceeded the electric circuit monitoring temperature.

[0030] The digital emergency electric safety control system of the present invention, i.e., the DESCON emergency system, is configured by a computer system including a server computer, etc. Although not shown, this computer system is equipped with a CPU that performs control so that various functions of the system of this embodiment are realized in accordance with an operating system and predetermined installed or downloaded computer programs, a ROM that stores the operating system and various computer programs and serves as a storage unit for storing data necessary for the CPU to execute various control processes, a RAM and a hard disk that store data necessary for the CPU to execute processes and are also used as a work area where information is rewritten by the CPU as appropriate, and information input / output units such as a communication interface, all of which are connected by the necessary bus lines.

[0031] The processing operations performed by the above-mentioned instantaneous current value determination device, first alarm notification information output means, power supply automatic cut-off possibility determination means, first power supply cut-off device, second power supply cut-off device, internal enclosure temperature monitoring means, circuit temperature information monitoring means, second alarm notification information output means, third alarm notification information output means, etc. are executed by such a computer system.

[0032] The instantaneous current value determination device, first alarm notification information output means, power supply automatic shutoff capability determination means, first power supply shutoff device, second power supply shutoff device, enclosure temperature monitoring means, circuit temperature information monitoring means, second alarm notification information output means, and third alarm notification information output means do not all need to be installed in a single device or device. For example, a power supply device may be equipped with a device or device having some of these components, which may be installed remotely from the power supply and connected to other devices or devices comprising a computer having the remaining components via a wired or wireless network. Alternatively, a power supply device may be equipped with a device or device having some of the above-mentioned components, which may be installed remotely from the power supply and connected to other devices or devices comprising a computer having some of the other components and other devices or devices comprising a computer having the remaining components via a wired or wireless network. In the above, the configuration may also include a server computer installed on the cloud among one or more other devices or equipment that are deployed at a location away from the power device, connected via a wired or wireless network, and that have some or the remaining configurations of the other configurations described above.

[0033] <Example of a Tracking Detection System in a DESCON Emergency System> The above-mentioned DESCON emergency system can be configured to include the tracking detection system described below. As shown in Fig. 16, this tracking detection system 1) converts the analog instantaneous AC current value detected by the current detection CT into an analog voltage value, 2) converts the analog voltage value into a digital voltage value, and 3) converts the digital voltage value into a current value to detect abnormal currents such as sparks and tracking.

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

[0035] This tracking detection system can measure, for example, current at a frequency of 50 Hz in 1 / 20,000 seconds and current at 60 Hz in 1 / 16,666 seconds, and can measure short-circuit currents such as instantaneous sparks and tracking phenomena, thereby detecting large currents caused by sparks and tracking.

[0036] Instantaneous current is detected in 1 / 20,000 second increments for 50 Hz and 1 / 16,666 second increments for 60 Hz, and the detected analog current value is converted to an analog voltage value, which is then converted to a digital voltage value, which is then further converted to a current value to detect abnormal currents such as sparks and tracking.

[0037] Such a tracking detection system can be called a DESCON tracking detection digital system. The above-mentioned DESCON tracking detection digital system is a tracking detection system for an electrical circuit through which an AC current flows.

[0038] <Another Example of Tracking Detection System in DESCON Emergency System> The above-mentioned DESCON emergency system can be configured to include another tracking detection system described below. As shown in Fig. 17, this tracking detection system 1) converts an analog instantaneous DC current value detected by an instantaneous DC current meter into an analog voltage value, 2) converts the analog voltage value into a digital voltage value, and 3) converts the digital voltage value into a current value to detect abnormal currents such as sparks and tracking.

[0039] As the DC instantaneous current measuring device, a Hall element detector, a fluxgate detector, or any other DC instantaneous current measuring device known in this technical field can be used, as exemplified in FIG.

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

[0041] This tracking detection system can be configured to measure current in 1 / 10,000 seconds to 1 / 100,000 seconds to 1 / n seconds, measure short-circuit currents such as instantaneous sparks and tracking phenomena, and detect large currents such as sparks and tracking.

[0042] Instantaneous current is detected in units of 1 / 10,000 seconds to 1 / 100,000 seconds to 1 / n seconds, the detected analog current value is converted to an analog voltage value, the converted analog voltage value is converted to a digital voltage value, and further converted to a current value, making it possible to detect abnormal current such as sparks and tracking.

[0043] For example, the tracking detection system may be used for DC electrical equipment such as motors for railways and electric vehicles, and DC power supply devices such as solar power generation and storage batteries.

[0044] Such a tracking detection system can be called a DESCON digital tracking detection system. The DESCON digital tracking detection system is a tracking detection system for an electric circuit through which a direct current flows.

[0045] <Example of Tracking Detection Function in DESCON Emergency System> The DESCON emergency system can be configured to have a tracking detection function, an example of which is explained in Fig. 20. The tracking detection function can be achieved by the tracking detection system in the DESCON emergency system described above.

[0046] This tracking detection function involves installing an instantaneous current detector (CT: Current Transformer) in the relevant circuit of a power distribution board, distribution panel, control panel, terminal equipment, etc., and detecting the analog current value detected in instantaneous time using the CT. The instantaneous time unit for analog current detection is, for example, 1 second / 12,000 (83 μsec) to 1 second / 50,000 (20 μsec). Alternatively, it may be 1 second / 100,000 (10 μsec) to 1 second / N value, depending on the performance of the PC.

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

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

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

[0050] If a current abnormality is detected by the above-described process and automatic shutdown is possible, the power supply supplying power to the circuit of the relevant distribution board is automatically shut off.

[0051] Additionally, an alert is sent to the PCs, tablets, smartphones, etc. of the relevant parties. This alert email can be sent multiple times until the relevant parties confirm and reset it, allowing for safe recovery after the automatic shutdown.

[0052] In addition, the panels and equipment of the relevant circuits can be checked remotely or on-site and adapted accordingly.

[0053] In this way, the tracking detection function provided in the DESCON emergency system, an example of which is shown in Figure 20, sends alerts and automatically shuts off the equipment, and continues to send alerts until the relevant parties confirm and reset the alerts, thoroughly controlling and preventing electrical burnouts and electrical fires.

[0054] <Example of Joule heat detection function in DESCON emergency system> The DESCON emergency system can be configured to have a Joule heat detection function, an example of which is explained in Figure 21. This Joule heat detection function monitors the temperature of the connection terminal block for each circuit in which a circuit breaker is installed. In other words, a temperature sensor monitors the temperature rise due to Joule heat in the connection terminal block.

[0055] Suppose a circuit equipped with a circuit breaker, for example, has cables with temperature-specific allowable temperatures, such as 60°C for IV / KIV, 60°C for VVF, 60°C for VCT, 75°C for HIV, 90°C for CV, and 90°C for MLFC. In this case, the allowable temperature of the wires, etc. is used as the standard, and the warning temperature of the cables, wires, etc. is determined in advance, for example, relative to the allowable temperature. For example, +10 to +15°C can be stored in a database, and when the relevant panel, cable, circuit, etc. reaches the warning temperature, an audio, numerical, or image alert can be sent to the PCs, tablets, and smartphones of those involved.

[0056] For example, a temperature sensor detects abnormal temperatures caused by temperature rises due to looseness, gaps, or misalignment of connection terminal blocks, etc.

[0057] If a temperature abnormality is detected and automatic shutdown is possible, the power to the circuit in the relevant distribution board will be automatically shut off.

[0058] If the temperature rises to a predetermined level, the power supply to the circuit of the relevant distribution board will be automatically shut off, and for example, the occurrence of spark tracking caused by the melting or burning of the electrical resistance coating of the relevant cable, wire, circuit, etc. will be detected and determined, making it possible to prevent electrical burns and electrical fire accidents.

[0059] In this case, an alert can be sent to the PC, tablet, smartphone, etc. of the person involved. The alert ringtone will ring until the person involved confirms and resets the setting, or multiple emails can be sent in succession with a continuous ringtone to prevent the person involved from missing the confirmation.

[0060] In addition, the panels and equipment of the relevant circuits can be checked remotely or on-site and adapted accordingly.

[0061] In this way, the Joule heat detection function provided in the DESCON emergency system, an example of which is shown in FIG. 21, transmits the above-mentioned alert and automatic shutoff continuously until the relevant person confirms the transmitted alert and resets it, thereby thoroughly controlling and preventing electrical burnouts and electrical fires.

[0062] <Example of Overcurrent Detection Function in DESCON Emergency System> The DESCON emergency system can be configured to have an overcurrent detection function, an example of which is explained in Fig. 22. This overcurrent detection function monitors the current value for each circuit in which a breaker is installed.

[0063] For example, an instantaneous current detector CT (Current Transformer) monitors overcurrent for each circuit.

[0064] The operating time of a breaker for each current value is, for example, when the rated current value is 30 A, the protective tripping operation time of the corresponding breaker for 1.25 times the rated current value, 37.5 A, is 60 minutes or less.

[0065] For example, if a circuit breaker or other wiring circuit breaker that protects a circuit is not installed properly, an overcurrent will occur in the circuit, causing the current to increase, resulting in a large increase in heat generation in the wires due to Joule heating. If this condition continues, the temperature of the wires will rise to a high level, causing the wire insulation to melt.

[0066] For example, the allowable temperatures for cables, wires, etc. by temperature, such as 60°C for IV / KIV, 60°C for VVF, 60°C for VCT, 75°C for HIV, 90°C for CV, and 90°C for MLFC, can be arbitrarily determined in advance based on the allowable temperatures. For example, caution temperatures for distribution boards, panel boards, junction boxes, connecting devices, terminal equipment, connecting facilities and equipment, electrical equipment and appliances, the cables, wires, etc. can be used as judgment information. For example, +10 to +15°C is stored in the database, and when the relevant boards, cables, circuits, etc. reach the caution temperature, audio, numerical, and image alerts are sent to the PCs, tablets, and smartphones of those involved.

[0067] An instantaneous current detector (CT) is installed in each of the above circuits to detect abnormalities in the current value, and a temperature sensor is used to detect temperature rises in the cables, wires, connectors, etc.

[0068] If an abnormality in current or temperature is detected and automatic shutdown is possible, the power supply to the circuit in the relevant distribution board will be automatically shut off.

[0069] If the temperature rises to a predetermined level, the power supply to the circuit in the relevant distribution board will be automatically cut off, and it will be possible to detect and determine the occurrence of spark tracking, for example, when the electrical resistance coating of the relevant cable, wire, circuit, etc. melts or burns, thereby preventing electrical burns and electrical fire accidents.

[0070] In this case, an alert is sent to the PC, tablet, smartphone, etc. of the person involved. The alert ringtone will ring until the person involved confirms and resets it, or an email can be sent multiple times in succession with the ringtone ringing to prevent the person involved from missing the confirmation.

[0071] The panels and equipment of the relevant circuits can be checked remotely or on-site and configured accordingly.

[0072] In this way, the overcurrent detection function provided in the DESCON emergency system, an example of which is shown in FIG. 22, transmits the above-mentioned alert and automatic shutoff continuously until the relevant person confirms the transmitted alert and resets it, thereby thoroughly controlling and preventing electrical burnout and electrical fires.

[0073] <Example of Leakage Current Detection Function in DESCON Emergency System> The DESCON emergency system can be configured to have a leakage current detection function, an example of which is shown in Fig. 23. This leakage current detection function monitors leakage overcurrent for each circuit in which a circuit breaker is installed using a leakage current detector ZCT (Zero-phase Current Transformer).

[0074] When ZCT detects an abnormality in the leakage current of a circuit, for example, if the leakage current reaches a predetermined value and automatic shutdown is possible, it will automatically shut off the power supply supplying the electrode to the circuit of the relevant distribution board. For example, it can detect and determine insulation defects such as deterioration of the relevant cables, wires, and circuits over time, making it possible to prevent electrical burnout, electrical fire accidents, and electric shock accidents.

[0075] When the leakage current value detected by the ZCT reaches the warning current value, an alert can be sent to the relevant person's PC, tablet, or smartphone with audio, numerical value, and image. The alert ringtone will continue to ring until the relevant person checks and resets it, or multiple emails can be sent in succession with the ringtone to prevent the relevant person from missing the check.

[0076] The panels and equipment of the relevant circuits can be checked remotely or on-site and configured accordingly.

[0077] In this way, the leakage current detection function provided in the DESCON emergency system, an example of which is shown in FIG. 23, transmits the above-mentioned alert and automatic shutoff continuously until the relevant person confirms the transmitted alert and resets it, thereby thoroughly controlling and preventing electrical burnout and electrical fires.

[0078] <Example of a Breaker System in a DESCON Emergency System> The above-mentioned DESCON emergency system can be configured to include a breaker system as described below. As shown in Fig. 19, this breaker system is a system in which the tracking detection function, Joule heat detection function, overcurrent detection function, leakage current detection function, and automatic shutoff function of the DESCON emergency system are incorporated into a molded case circuit breaker to prevent electrical fires and burnout accidents.

[0079] 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 detector ZCT (Zero-phase Current Transformer) in the above-mentioned leakage current detection function are all built into the circuit breaker.

[0080] This allows the breaker system to detect abnormalities in tracking, Joule heat, overcurrent, leakage current, etc., for example, on a main breaker (wired circuit breaker) basis for each circuit in a distribution board, panel board, control panel, electrical equipment, load device, etc., and if it detects abnormal values ​​for predetermined tracking current, temperature, overcurrent, or leakage current, it will send an alert in the form of audio and image to the PCs, tablets, smartphones, etc. of those involved.

[0081] In addition, if a predetermined alarm current, alarm temperature, or alarm leakage current is detected, an alert can be sent via audio and image to the relevant person's PC, tablet, smartphone, etc., and the relevant circuit or main breaker can be automatically shut off.

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

[0083] <Various embodiments of the DESCON emergency system of the present invention and various functions to be exerted> The DESCON emergency system is configured to detect current, voltage, temperature, images, etc. of substation equipment, distribution boards, panel boards, control panels, main lines, circuits, breakers, remote devices, etc., as well as load terminal equipment, electrical equipment equipment, etc., and determine whether the value is normal or abnormal by referring to various databases that have been entered in advance. For example, when each abnormal value is detected, an alert signal is sent to the relevant parties at the warning level, with information such as the customer name, building name, facility name, location, light on the relevant panel or circuit, type of power, capacity, electrical equipment at the system terminal, name of load equipment, etc., in the form of audio, numerical values, images, etc., and an alert is sent in real time to a PC, tablet, or smartphone.

[0084] According to the DESCON emergency system, if the abnormal value becomes high, "an alert is sent using audio, images and numbers as a warning signal," "the panel, main line, circuit, breaker, etc. of the relevant equipment is automatically shut off," "an alert is sent using audio, images and numbers to the relevant parties that the automatic shutoff has occurred," "the alert is sent continuously until the relevant parties confirm and reset," and an embodiment can be created that "safely responds to recovery in real time after the automatic shutoff."

[0085] The above-mentioned automatic shutdown is, for example, when automatically shutting off products, production, etc. by computer programs such as AI, IoT, etc., lighting, elevators, etc. in logistics centers, large freezers, refrigerators, etc., commercial facilities where many people gather, terminal buildings, hotels, etc., data centers for important data research test results, etc., infrastructure substations, etc., and various facilities, electrical equipment, etc. in transportation trains, ships, etc., as described above, and when these are controlled by a computer based on a computer program, the terminal equipment, etc. for control, etc., is shut off by a predetermined program. In the case of shutting down, 2) the DESCON emergency system is composed of remote devices for each system such as distribution boards, distribution boards, control panels, main lines, circuits, breakers, etc., and a cloud server, LAN, etc., and by using an emergency response protection program via the remote devices for each system, cloud server, LAN, etc., the remote devices for the relevant distribution boards, distribution boards, control panels, etc. send a signal to the protection stop device, and all or selected terminal equipment, etc., such as control devices, are shut down by a predetermined program, and is characterized by a stop function control means for normal and safe shutdown, and a control means for the function of confirming the stop signal.

[0086] The DESCON emergency system calculates and judges whether the current, voltage, insulation, temperature, etc. of the facilities, main lines, circuits, breakers, terminal load facilities, electrical equipment, etc. are normal or abnormal, and sends this information to the relevant person's PC, tablet, smartphone, etc. using a predetermined program that includes, for example, the customer name, building name, facility name, location, and the lights and power of each panel circuit, etc., along with numerical values ​​such as yearly, seasonal, monthly, weekly, daily, hourly, and minutely comparisons, and records the numerical values ​​of the current, voltage, insulation, temperature, etc., along with whether they are normal or abnormal, in a database.An embodiment in which the program periodically displays this information on the relevant person's PC, tablet, smartphone, etc. and on a display, or automatically prints it out.

[0087] The DESCON Emergency System is connected to a fire alarm on the disaster prevention panel of a building facility, for example, a fire alarm, and receives abnormal signals from the smoke detector and heat detector of the fire alarm. It identifies the floor and area where the signal was received, and automatically shuts off the electricity, outside the equipment, and predetermined lights and power equipment required for evacuation, safety, etc., such as evacuation, fire alarms, emergency guide lights for broadcasting equipment, lighting, mechanical smoke exhaust, and air supply. It then sends audio, image, and numerical alerts to relevant parties in real time via PC, tablet, or smartphone, including, for example, the customer name, building name, facility name, location, type and capacity of lights and power on the relevant panel, circuit, etc., and continues to send these alerts until the relevant parties confirm and reset, allowing for an embodiment in which recovery after automatic shutoff can be safely handled in real time.

[0088] The DESCON Emergency System is used in cases where there is a risk of a tracking phenomenon occurring, for example, when dust, dirt, etc. accumulates on the connecting fittings of distribution boards, panel boards, control panels, terminal equipment, electrical equipment, etc. in a power receiving and transforming equipment system over a long period of time, or when the relevant connecting fitting circuits, terminal fittings, etc. loosen due to moisture, etc., or in proportion to the elapsed time, the system allows for, for example, a caution temperature, an alarm temperature, etc. to be determined in advance, programmed, and input, and when the alarm temperature is reached, an alert is sent to the PCs, smartphones, tablets, etc. of the relevant parties, with information such as the customer name, building name, facility name, location, type and capacity of light and power on the relevant panel, circuit, etc., and this continues to be sent until the relevant parties confirm and reset, and the relevant cables, circuits, etc. are automatically shut off, an alert that the automatic shutoff has occurred is sent to the relevant parties, and this continues to be sent until the relevant parties confirm and reset, and this can be an embodiment that allows for safe recovery measures after the automatic shutoff.

[0089] The DESCON Emergency System is designed to detect and treat electrical fires and other accidents that may occur when dust, dirt, etc. accumulates on the connecting metal fittings of power distribution boards, distribution boards, control panels, terminal equipment, electrical equipment, etc. in a power receiving and transforming system over a long period of time, or when moisture or other factors cause the connecting metal fitting circuits and terminal metal fittings to loosen over time, resulting in Joule heat being generated in the wiring and circuits due to an increase in electrical thermal resistance in gaps, etc., which exceeds the allowable temperature for each type of wire. This causes the temperature of each wire, etc. to exceed the allowable temperature for that type, causing the insulating coating material to deform and melt in proportion to the high temperature, resulting in a short circuit or spark between the + and - terminals, and causing an electrical fire or other accident. If there is a risk of this, for example, caution temperatures, alarm temperatures, etc. can be arbitrarily determined, programmed, and input in advance, and if the alarm temperature is reached, an alert is sent to the PC, smartphone, tablet, etc. of the relevant person, with, for example, the customer name, building name, facility name, location, light, power type, capacity of the relevant panel, circuit, etc., and this is transmitted continuously until the relevant person confirms and resets, the relevant cable, circuit, etc. is automatically shut off, an alert that the automatic shutoff has occurred is sent to the relevant person, and this is transmitted continuously until the relevant person confirms and resets, and an embodiment can be made in which recovery and safety measures can be taken after the automatic shutoff.

[0090] In the DESCON emergency system, as the age of the panel connectors, terminals, cables, wiring, circuits, etc. of the distribution boards, distribution boards, control panels, terminal equipment, electrical equipment, etc. of the power receiving and transforming equipment system increases, the connectors become loose in proportion to the age of the system, and the conductive area decreases due to gaps, etc., causing electrical resistance heat to be generated. The temperature rises due to Joule heat in proportion to the elapsed time, and if there is a risk that the allowable temperature of each electric wire will be reached or exceeded, for example, a caution temperature or alarm temperature can be arbitrarily determined and programmed and input in advance, and if the alarm temperature is reached, an alert is sent to the PCs, smartphones, tablets, etc. of the relevant parties, with information such as the customer name, building name, facility name, location, light, power type, capacity of the relevant panel, circuit, etc., and this information continues to be sent until the relevant parties confirm and reset, and the relevant cables, circuits, etc. are automatically shut off, an alert that the automatic shut off has been sent to the relevant parties, and this information continues to be sent until the relevant parties confirm and reset, so that an embodiment can be implemented that allows for safe recovery measures after the automatic shut off.

[0091] The DESCON Emergency System detects in an extremely short time the current that instantly shorts out and sparks when the insulating coating of the wires and circuits melts and burns due to the adhesion of dust, dirt, etc. to panels, connecting fittings, terminals, circuits, terminal devices, etc., or when the temperature of panels, connecting fittings, terminals, circuits, electric wires, etc. rises, and detects the current value of the short circuit or spark that is 50 to 80 times the normal current magnification, for example, due to the tracking phenomenon of shorts and sparks. At a current value of, for example, 50 to 80 times the aforementioned predetermined value, an alert signal for a short circuit or a spark warning is sent to the PC, smartphone, tablet, etc. of the person in question, and information such as the customer name, building name, facility name, location, the light, power type, capacity of the relevant panel, circuit, etc. is transmitted, and the relevant panel, circuit, etc. is automatically shut off, and an alert that the automatic shutoff has occurred is sent to the person in question, and this is transmitted multiple times until the person in question confirms and resets, making it possible to implement an embodiment in which recovery can be safely performed after the automatic shutoff.

[0092] The detection in an extremely short time can be instantaneous detection in, for example, 1 / 12000 seconds = 83 microseconds, where 12000 is a common multiple of, for example, 50 Hz and 60 Hz.

[0093] The DESCON emergency system detects overcurrents that exceed the rated current in the power receiving and transforming equipment, distribution boards, panelboards, control panels, terminal equipment, electrical equipment, etc., and the current (A) of main lines, circuits, etc., for example, rated current 30A or less, 30A to 50A or less, 445A to 400A or less, 800A to 1000A or less, 1600A to 2000A or less, etc. If the allowable current is 1.25 times the rated current, the allowable current breaker will operate for 60 minutes or less, and if the allowable current is 2.0 times the rated current, the allowable current breaker will operate for 6 In relation to the safety protection of electrical equipment, if the current exceeds the rated current, the breaker will operate at the specified time. However, for example, if the required current of a specific unit, linked connection, etc. of the relevant terminal load equipment, electrical equipment, etc. is not the current value set above, for example, until the breaker operates, it may be a weak overcurrent that requires a long time, or if the insulation coating material has worn out due to aging, etc., and the equipment is operating 24 hours a day, the breaker may operate due to the overcurrent situation of the equipment. Before the maximum allowable temperature of the high-voltage transformer and the load coefficient of the low-voltage light and power equipment capacity of the same equipment reach the allowable coefficient, a warning temperature and a warning current can be arbitrarily determined in advance, and an alert can be sent to the PC, smartphone, tablet, etc. of the relevant person, for example, with information such as the customer name, building name, facility name, location, relevant panel, type of light and power, capacity of the circuit, etc., and the alert can be sent multiple times until the relevant person confirms and resets. This is a system that reduces and lowers the maximum allowable temperature of the transformer of the substation equipment, the load coefficient of the allowable current, and the overcurrent coefficient before the operating coefficient of the coefficient exceeds the allowable coefficient, by automatically shutting off the relevant low-voltage lights, power distribution boards, electric lights, power distribution boards, control panels, terminal load equipment, electrical equipment, etc. by determining the priority order in advance so that they do not require automatic shutdown, and automatically shutting them off.After automatic shutdown, an alert is sent to the relevant parties that an automatic shutdown has occurred, and this is continued until the relevant parties confirm and reset, and an embodiment can also be made that allows for safe recovery measures after automatic shutdown.

[0094] <Flow of one embodiment of the tracking detection function in the DESCON emergency system> An instantaneous AC current detector is installed in the relevant circuit of a switchboard, distribution board, control panel, terminal equipment, etc., and an analog current value detected at an instantaneous time is detected. The instantaneous current value of the relevant circuit of a switchboard, distribution board, control panel, terminal equipment, etc. is detected. As the instantaneous AC current detector, a current sensor using an instrument current transformer called a CT (Current Transformer) can be used. Note that in this specification and drawings, the instantaneous AC current detector may be simply referred to as "CT."

[0095] As described above, instantaneous detection can be performed in 1 / 12000 seconds, which is obtained by dividing by 50×60×4=12000, which is the common multiple of 50 Hz and 60 Hz.

[0096] As mentioned above, the unit of time for instantaneous time detection is, for example, 1 / 12000 seconds = 83 microseconds, and can be set arbitrarily between 1 / 50,000 seconds (= 20 μsec) and 1 / 100,000 seconds (= 10 μsec). Furthermore, within this range, the microsecond can be set in proportion to the performance of the computer (PC) that makes up the DESCON emergency system.

[0097] Setting the instantaneous time unit for instantaneous time detection to microseconds between 1 / 50,000 seconds (=20 μsec) and 1 / 100,000 seconds (=10 μsec) is advantageous in that it enables the risk of a tracking phenomenon occurring to be detected earlier and necessary measures, such as cutting off the power supply, to be taken before the tracking phenomenon occurs.

[0098] Subsequently, the instantaneous current value detected as described above is compared with a preset allowable current value to determine whether the circuit in question is experiencing a short circuit, spark, tracking phenomenon, or the like.

[0099] For example, an instantaneous current value that is 30 times the allowable current value, which is the current value allowed in the relevant circuit of a distribution board, panel board, control panel, terminal equipment, etc., is determined to be an abnormal current that could lead to a short circuit, spark, tracking phenomenon, etc. in the relevant circuit.

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

[0101] As described above, after detecting the instantaneous current value as an analog current value, the analog current value can be converted into an analog voltage value.

[0102] For example, an analog current value detected in an instantaneous time period of 1 / 50,000 seconds (=20 μsec) to 1 / 100,000 seconds (=10 μsec), such as 1 / 12,000 seconds (83 μsec), is converted into an analog voltage value.

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

[0104] The digital current value thus converted can be treated as the detected instantaneous current value, and as described above, this can be compared with a preset allowable current value to determine whether the circuit in question has a short circuit, spark, tracking phenomenon, etc.

[0105] When the detected instantaneous current value is compared with the preset allowable current value and it is determined that the current is abnormal and could lead to a short circuit, spark, tracking phenomenon, etc. in the circuit in question, it is determined whether it is possible to automatically shut off the circuit in question, such as in the distribution board, panel board, control panel, or terminal equipment.

[0106] When it is determined that automatic shutdown is possible, the power supply to the circuit in question is automatically shut off.

[0107] On the other hand, if the circuit in question that has been determined to have an abnormal current is controlled by a computer or the like, and it is necessary to first shut off the controlling computer or the like before cutting off the power, the configuration can be such that first the power supply to the controlling computer or the like is cut off, and then the power supply is cut off.

[0108] An alert is sent to the PCs, tablets, smartphones, etc. of the relevant parties. The alert email is sent multiple times until the relevant parties confirm and reset, making it a system that can safely restore operation after automatic shutdown. The panels and equipment of the relevant circuits can be checked and responded to remotely or on-site.

[0109] <DESCON Emergency System Joule Heat Detection Function Flow> Monitors the temperature of wires, connectors, etc. by circuit Temperature sensors monitor temperature rises in cables, wires, etc. due to Joule heat.

[0110] For example, the allowable temperatures of cables, wires, etc. by temperature, such as IV / KIV allowable temperature 60 degrees, VVF allowable temperature 60 degrees, VCT allowable temperature 60 degrees, HIV allowable temperature 75 degrees, CV allowable temperature 90 degrees, MLFC allowable temperature 90 degrees, etc., are used as standards, and the warning temperatures of, for example, distribution boards, panel boards, junction boxes, connecting devices, terminal equipment, connecting equipment, electrical equipment and appliances, the cables, wires, etc. are determined in advance, and, for example, +10 to +15 degrees are stored in a database, and when the relevant boards, cables, circuits, etc. reach the warning temperature, a voice, numerical value, and image alert is sent to the PCs, tablets, and smartphones of the relevant people.

[0111] Detects temperature abnormalities: Temperature sensors detect temperature increases caused by loose terminal blocks, gaps, or disconnections.

[0112] If automatic shutdown is possible, the power supply to the circuit in the relevant distribution board will be automatically shut off.

[0113] If the temperature rises to a predetermined level, the power supply to the circuit of the relevant distribution board is automatically cut off, and the system is characterized by a means for detecting and determining the occurrence of spark tracking, for example, when the electrical resistance coating of the relevant cable, wire, circuit, etc. melts or burns, making it possible to prevent electrical burns and electrical fire accidents.

[0114] Alerts are sent to relevant parties' PCs, tablets, smartphones, etc.

[0115] The alert ringtone will continue to ring until the relevant person confirms and resets it, or an email will be sent multiple times in succession with the ringtone to prevent the relevant person from missing a check. The relevant circuit board and equipment will be checked and handled remotely or on-site.

[0116] <An example of the overcurrent detection function flow of the DESCON emergency system> Monitors overcurrent by circuit Install an AC instantaneous current detector (CT) on the relevant circuit of the distribution board, panel board, control panel, terminal equipment, etc. to monitor overcurrent by circuit.

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

[0118] For example, if a circuit breaker or other wiring circuit breaker that protects a circuit is not installed properly, an overcurrent will occur in the circuit, causing the current to increase, resulting in a large increase in heat generation in the wires due to Joule heating. If this condition continues, the temperature of the wires will rise to a high level, causing the wire insulation to melt.

[0119] For example, the allowable temperatures of cables, wires, etc. by temperature, such as IV / KIV allowable temperature 60 degrees, VVF allowable temperature 60 degrees, VCT allowable temperature 60 degrees, HIV allowable temperature 75 degrees, CV allowable temperature 90 degrees, MLFC allowable temperature 90 degrees, etc., are used as standards, and the warning temperatures of, for example, distribution boards, distribution boards, junction boxes, connecting devices, terminal equipment, connecting equipment, electrical equipment / tools, the cables, wires, etc. are determined based on the allowable temperatures that have been arbitrarily determined in advance, and for example, +10 to +15 degrees are stored in a database, and when the relevant boards, cables, circuits, etc. reach the warning temperature, audio, numerical values, and images are sent as alerts to the PCs, tablets, and smartphones of those involved.

[0120] Detecting current and temperature abnormalities An AC instantaneous current detector CT is installed for each of the above circuits to detect abnormalities in the current value, and temperature sensors are used to detect temperature increases in cables, wires, connecting fittings, etc.

[0121] If automatic shutdown is possible, the power supply to the circuit in the relevant distribution board will be automatically shut off.

[0122] If the temperature rises to a predetermined level, the power supply to the circuit of the relevant distribution board is automatically cut off, and the system is characterized by a means for detecting and determining the occurrence of spark tracking, for example, when the electrical resistance coating of the relevant cable, wire, circuit, etc. melts or burns, making it possible to prevent electrical burns and electrical fire accidents.

[0123] An alert is sent to the PC, tablet, smartphone, etc. of the relevant person. The alert ringtone will ring until the relevant person confirms and resets it, or an email will be sent multiple times in succession with the ringtone ringing, preventing the relevant person from missing a confirmation.

[0124] Check and respond to the panels and equipment of the relevant circuits remotely or on-site.

[0125] Any number of Joule heat and current detection devices can be installed on the power supply line, from 1 to n.

[0126] The detector may be connected to a power line but not to a network.

[0127] Each sensing device is connected in some way directly to an upstream remote device and may be configured to send a signal to the remote device.

[0128] The Joule heat and current detection device described above can be directly connected to a remote device outside the control panel. Alternatively, one to n Joule heat and current detection devices (P4 to P5) arbitrarily installed on the power line can be directly connected to the remote device 2 inside the control panel.

[0129] <One embodiment of the flow for shutting down when temperature or current abnormality is detected> The Joule heat and current detection device described above sends the values ​​of its built-in sensor to the remote device. When the remote device detects an abnormality in temperature or current, it activates the corresponding breaker to shut down the power.

[0130] The central control device that makes up the DESCON emergency system sends shutdown notifications to relevant parties' PCs, tablets, smartphones, etc. via a cloud server.

[0131] <Another embodiment of the flow for shutting down when temperature or current exceeds the limit> The Joule heat and current detection device sends the value of its built-in sensor to the corresponding remote device. When the corresponding remote device detects an exceedance in temperature or current, it activates the corresponding breaker to shut down the power.

[0132] The central control device that makes up the DESCON emergency system sends shutdown notifications to the PCs, tablets, smartphones, etc. of the relevant parties via a cloud server. <Deployment method for Joule heat and current detection devices> The information network (A) and control network (B) that make up the DESCON emergency system can use the Internet (open public network) in places on the WAN (wide area network). There is no particular problem with using the Internet when sending shutdown notifications to the PCs, tablets, smartphones, etc. of the relevant parties.

[0133] However, in addition to sending shutdown notifications, when connecting between bases and performing remote access, it is possible to consider security by using a dedicated line or VPN (closed network) instead of the Internet. In that case, the WAN portion will be replaced as necessary. <Tracking detection function in the DESCON Emergency System> Conventional electrical protection breakers, for example, measure current time using an ammeter (CT) or the like in units of hours, minutes, and seconds, and for a power frequency of 50 Hz, they measure it in, for example, typically 0.1 sec (100 msec), and for 60 Hz, they measure it in typically 0.083 sec (83 msec). They also have safety protection functions such as thermally activated breakers and ground fault breakers that shut off the relevant circuits to protect against overcurrents and ground faults in electrical equipment. However, the tracking phenomenon, in which the relevant part shorts out or sparks instantly, as described above, occurs in conventional electrical mains, cables, wiring, etc., and when the power frequency is 50 Hz, for example, it is usually 0.1 sec (100 msec), and when it is 60 Hz, it is usually 0.083 sec (83 msec). Conventional earth leakage breakers, which operate by thermal activation, do not detect the phenomenon of electrical burnout or fire and do not operate to protect, so electrical burnout, electrical fire accidents, etc. occur in an instant, which is the current situation with conventional protective breakers.

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

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

[0136] The digital voltage value obtained by converting the digital voltage into a current is converted into a digital current value as described above, and the current value of an abnormal phenomenon that occurs instantaneously due to a short circuit or spark in the circuit in question is detected in an arbitrarily determined instantaneous time period, for example, from 1 / 50,000 seconds (=20 μsec) to 1 / 100,000 seconds (=10 μsec), such as 1 / 12,000 seconds (83 μsec).

[0137] Next, the power frequency can be, for example, 50 Hz, 60 Hz, or other frequencies. The instantaneous analog current (CT current) of short circuits, sparks, tracking, and other phenomena occurring in the equipment is converted into a voltage. For example, an analog-to-digital converter (A / DC) is installed in the relevant circuit, and the detected analog current value is converted into a digital voltage value. The converted digital voltage value is then converted into a digital voltage. The analog current value detected over an arbitrary instantaneous time period, for example, between 1 / 50,000 seconds (= 20 μsec) and 1 / 100,000 seconds (= 10 μsec), such as 1 / 12,000 seconds (83 μsec), is then converted into a digital voltage. The predetermined warning current and multiplication factor, warning current and multiplication factor are then determined based on the normal current multiplication factor. An alert of the warning current and multiplication factor and warning current and multiplication factor is then sent to the relevant person's PC, tablet, or smartphone.

[0138] The DESCON emergency system detects the current by installing the current detection device CT in the relevant circuit and converting the current into voltage. For example, the current is converted into voltage using the functions of a computer, PC, microcomputer, etc. and a printed circuit board, and the current is converted into voltage and an analog-to-digital converter is used to detect instantaneous current of, for example, 1 / 12,000 seconds = 83 μsec for power frequencies of 50 Hz and 60 Hz.

[0139] Instantaneous current is detected in units of 83 μsec (1 / 12,000 seconds), the detected analog current is converted into an analog voltage value, the converted analog voltage value is A / D converted into a digital voltage value, and then converted into a current value by the CPU, thereby detecting abnormal current such as sparks and tracking.

[0140] The current value detected by the CT, for example, is converted into a voltage of 1 / 12,000 seconds (83 μsec) in hours, minutes, and seconds, and the current A is inverted from 0 A, which is the AC power inversion from a positive number to a negative number, and the normal magnification of each current A is calculated using, for example, the initially detected negative current of -1.4 A, a current of -81.7 A that is 15 times or more of an arbitrarily predetermined normal current A, multiplied by 19.9, with the current immediately preceding -4.1 A as the denominator, and the current in each 80 μsec unit is -4.1 A as the denominator, and the average negative current of -2.0 A from the negative current of -1.4 A to the negative current of -4.1 A is calculated, for example, using the three methods, etc., for 83 μsec of 12,000 detections per second.

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

[0142] The DESCON emergency system can be configured to input a predetermined, arbitrarily determined predicted magnification of the spark tracking phenomenon, for example 15 times, into the program as the positive and negative currents, and to have a judgment means that sends an alert to the PCs, smartphones, tablets, etc. of relevant parties when a spark tracking phenomenon occurs at 20 times or more, and to automatically shut off the relevant circuit when the magnification is 25 times or more.

[0143] The DESCON emergency system can be configured to thoroughly control and prevent electrical burnout and electrical fires by repeatedly transmitting the alert and automatic shutoff function until the relevant person confirms and resets the transmitted alert.

[0144] As a result of the above, it is possible to create a system that can measure currents with frequencies of 50 Hz and 60 Hz in 1 / 12,000 seconds of 83 μsec, measure short-circuit currents such as instantaneous sparks and tracking phenomena, and detect large currents such as sparks and tracking.

[0145] The DESCON emergency system is configured to detect analog current values ​​at instantaneous time intervals by installing an AC instantaneous current detector (CT) in the relevant circuit of a distribution board, panel board, control panel, terminal equipment, etc. As mentioned above, the instantaneous time unit may be, for example, 1 / 50,000 seconds (=20 μsec) to 1 / 100,000 seconds (=10 μsec), or even 1 / 12,000 seconds (83 μsec).

[0146] The DESCON emergency system detects abnormal current values ​​such as short sparks and tracking phenomena from instantaneous current values ​​in hours, minutes and seconds, such as 1 / 50,000 seconds (=20 μsec) to 1 / 100,000 seconds (=10 μsec), for example, 1 / 12,000 seconds (83 μsec). For example, in relation to verification data for electric lighting equipment, the current magnification immediately before tracking after AC reversal = each current A / -1.4A, the magnification of the average current from 4.15 ms to 7.47 msec after AC reversal = each current A / -2.0A, and the current magnification immediately before tracking = each current A / -4.1A are detected in elapsed time units of 1 / 12,000 seconds (83 μsec), and the DESCON emergency system converts these current values ​​into an arbitrarily determined current value of 1 / 12,000 seconds = 83 μsec, and detects current values ​​for short circuits, sparks, tracking phenomena, etc.

[0147] For example, current values ​​detected in 83 μsec elapsed time units for lighting equipment, such as current magnification immediately before tracking after AC reversal = each current A / -1.4 A, magnification of average current from 4.15 ms to 7.47 msec after AC reversal = each current A / -2.0 A, current magnification immediately before tracking = each current A / -4.1 A, etc., and current values ​​that are 30 to 100 times the allowable current value, for example, are defined as short circuits, sparks, and tracking phenomena, and a warning current value and magnification of, for example, 10 to 50 times the magnification of the above current value, is sent to the PC, smartphone, tablet, etc. of the relevant person as an alert, and this is sent multiple times until the relevant person confirms and resets it.

[0148] The alarm current value and magnification are set to a preset value, for example, 20 to 70 times, and the relevant circuits of the relevant low-voltage lighting, power distribution panel, control panel, terminal load equipment, electrical equipment, etc. are automatically shut off, and an alert is sent to the relevant parties that the automatic shutoff has occurred. This is sent multiple times until the relevant parties confirm and reset, allowing for safe recovery after the automatic shutoff.

[0149] Regardless of the above, the normal current value may be determined by using the allowable current of each electric wire or the required current value of the terminal load equipment or electrical equipment connected to the relevant panel, etc. as the denominator, and, as above, this current value may be multiplied by, for example, 30 to 100 times the current value that spikes instantaneously during a short circuit, spark, or tracking phenomenon. <Example of the configuration of the DESCON emergency system> An AC instantaneous current detector (CT) is installed in the relevant circuit of a distribution board, switchboard, control panel, terminal equipment, etc., and the analog instantaneous current value is detected in units of 83 μsec = 1 / 12,000 seconds.

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

[0151] A / D conversion: The converted analog voltage value is A / D converted into a digital voltage.

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

[0153] The current detector (CT) is attached to the relevant circuit to detect the current and convert it into a voltage. For example, the current is converted into a voltage using the function of a printed circuit board such as an IC. The current-to-voltage conversion system can be configured to detect instantaneous current of, for example, 12,000 times per second = 83 μsec, which is a common multiple of the power frequencies of 50 Hz and 60 Hz.

[0154] For example, using the current A detected in 83 μsec units, 0 A where AC power is inverted from a positive number to a negative number, for example, the initially detected negative current of −1.4 A, a current that is 15 times or more the predetermined normal current A, multiplied by 19.9 times of −81.7 A, and the immediately preceding current of −4.1 A as the denominator, the current in each 80 μsec unit is calculated as the denominator −4.1 A, and the average negative current of −2.0 A from the negative current of −1.4 A to the negative current of −4.1 A, for example, the normal multiplication factor of each current A is calculated for 83 μsec with 12,000 detections per second using three methods, etc.

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

[0156] The DESCON emergency system is equipped with a judgment means for inputting the positive and negative currents into the program as a predetermined predicted magnification for the spark tracking phenomenon, for example 15 times, and sending an alert to the PCs, smartphones, tablets, etc. of relevant parties when a spark tracking phenomenon occurs at 20 times or more, and can be configured to perform control to automatically shut off the relevant circuit at 25 times or more.

[0157] The DESCON emergency system can be configured to thoroughly control and prevent electrical burnouts and fires by repeatedly transmitting the alerts and automatic shutoff function until the relevant parties confirm and reset the alerts.

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

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

[0160] A / D conversion: The converted analog voltage value is A / D converted into a digital voltage.

[0161] Converting digital voltage to current: The CPU converts the converted digital voltage value into a current value to detect abnormal current such as tracking current in the relevant circuit. <Example of system flow for the DESCON Emergency System> An AC instantaneous current detector (CT) is installed in the relevant circuit of the distribution board, switchboard, control panel, terminal equipment, etc., and the current of the relevant circuit is detected in 83 μsec (1 / 12,000 second) units to detect abnormal current values ​​due to the sparc tracking phenomenon.

[0162] The DESCON Emergency System installs AC instantaneous current detectors (CT) on panels and wiring that are required in advance, such as the main and distribution panels for low-voltage lighting and power equipment, branch trunks for each system, distribution panels, control panels, and control panels for terminal equipment, in the power receiving and transforming equipment of electrical equipment. Each current A is input into the DESCON Emergency System's remote device, and the analog data from the ammeter CT is converted into voltage, and the digital voltage is then converted into a current of 83 μsec, for example.

[0163] The central control device of the computer that makes up the DESCON emergency system enters the 83 μsec current of the relevant circuit into a database, and if it reaches a preset multiplier of the current A, it sends an alert, and if it exceeds the predetermined current A, it automatically shuts off the relevant circuit, and sends the data to a server device made up of the computer that makes up the DESCON emergency system, and then to headquarters or the PCs, smartphones and tablets of those involved, preventing spark tracking from occurring.

[0164] The DESCON emergency system sends alerts and automatically shuts off the power, and the system continues to send alerts multiple times until the relevant parties confirm the alert and reset it, completely preventing electrical burnouts and fires.

[0165] <Configuration of the remote devices that make up the DESCON emergency system> Built-in remote device A CT is installed in the relevant circuit of a distribution board, switchboard, control panel, terminal equipment, etc., and a remote device (sometimes called a "DESCON remote device") is installed inside the relevant panel, detecting abnormal currents such as tracking currents in the relevant circuit to within 83 μsec = 1 / 12,000 seconds. Separately installed (not built-in) remote device A CT is installed in the relevant circuit of a distribution board, switchboard, control panel, terminal equipment, etc., and a DESCON remote device is installed near the relevant panel, detecting abnormal currents such as tracking currents in the relevant circuit to within 83 μsec = 1 / 12,000 seconds, for example.

[0166] The remote device in the DESCON emergency system can be either the built-in type or the separate type, depending on the shape and situation of the relevant panel, etc.

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

[0168] The DESCON emergency system converts the instantaneous current value (analog instantaneous current value) detected by an attached CT into analog voltage, which is the instantaneous current value that leads to the spark tracking phenomenon at, for example, secondary terminal appliance outlets of low-voltage distribution boards, distribution boards, control panels, load terminal equipment, electrical devices, etc., and then converts the analog voltage into digital voltage measured for, for example, 83 μsec at 1 second / 12,000, and uses a connected CPU to measure the digital voltage as verification data for a short circuit and spark current over 83 μsec.

[0169] Using the normal normal current A measured as described above as the denominator of the constant current, the device detects and automatically judges whether a predetermined arbitrary current, for example, the instantaneous current measured over 83 μsec, is 20 times or 25 times or more, and sends an alert to the relevant person's PC, smartphone, tablet, etc., notifying them of the relevant building, floor, area, layout, etc., as well as details such as the spark tracking current A and magnification, and has a protective function that automatically shuts off the relevant circuit, main line, connecting fittings, control panel, etc., or terminal load equipment, electrical equipment, electrical appliances, etc.

[0170] An alert can be sent multiple times until the relevant person confirms the transmission and resets it, thereby thoroughly preventing electrical burnout and electrical fire accidents, and implementing functional restoration and safety measures for the relevant equipment in real time.

[0171] For example, the data is an instantaneous current value measured 12,000 times over 83 μsec, which is a common multiple of the power frequencies 50 Hz and 60 Hz. Single-phase 100 V, 50 Hz Breaker capacity: 20 A Load equipment: 200 W incandescent bulb Rated current: 2 A Instantaneous current measurement sampling period: 83 μsec Unit: 1 μsec = 1 / 1,000 ms = 1 / 1,000,000 s

[0172] The DESCON emergency system can be embodied in such a way that, for example, the positive current AC inversion axis, for example, from 0 A at an elapsed time of 3.32 ms to the negative instantaneous current of -1.4 A at 4.15 ms after 83 μsec has elapsed, is stored as a constant in a database, and if the circuit of the relevant system suddenly experiences a spark tracking phenomenon, an alert is sent as a warning signal to the PCs, smartphones, tablets, etc. of the relevant persons if the current value becomes 15 to 20 times the predetermined, arbitrarily determined positive or negative value, and the circuit of the relevant system is identified and automatically shut off if the current value becomes 20 times or more.

[0173] Furthermore, an alert can be sent to the relevant parties informing them of the automatic shutdown when tracking occurs, and alerts can be sent continuously until the relevant parties confirm and reset, thereby ensuring the safe recovery of the relevant circuit and the complete business or functionality.

[0174] The DESCON emergency system can also be embodied in such a way that, for example, from 0 A at 3.32 ms elapsed time on the AC inversion axis of the positive current, the average current of -2.0 is (negative instantaneous current at 4.15 ms after 83 μsec has elapsed -1.4 A) + (negative current at 4.98 ms elapsed time -0.8 A) + (negative current at 5.81 ms elapsed time -2.0 A) + (negative current at 6.64 ms elapsed time -1.7 A) + (negative current at 7.47 ms elapsed time -4.1 A) / 5 = -2.0, and an arbitrarily predetermined average current of -2.0 A can be used as the denominator of the constant to detect sparking / tracking phenomena at a current magnification of 20 times or more.

[0175] The DESCON emergency system can also detect the relevant current multiplication factor using the constant denominator of -4.1A 0.83 ms before the sparking tracking phenomenon, which is a current multiplication factor of 15 to 20 times or more, as the denominator for the constant, for example, from 0 A at 3.32 ms elapsed time on an arbitrarily determined positive current AC inversion axis, to: a negative instantaneous current of -1.4 A at 4.15 ms after 83 μsec has elapsed, a negative current of -0.8 A at 4.98 ms elapsed time, a negative current of -2.0 A at 5.81 ms elapsed time, a negative current of -1.7 A at 6.64 ms elapsed time, a negative current of -4.1 A at 7.47 ms elapsed time, and -81.7 A at 8.30 ms elapsed time.

[0176] For example, the DESCON emergency system can be embodied in such a way that, from the positive currents, the measured current of -1.4 A at the beginning of the negative current after AC reversal 0 is detected as 3.32 ms, and the corresponding multiplication factor of each measured current A is detected using -1.4 as the denominator, and the average current of (measured current -1.4 A... + measured current at 7.47 ms elapsed time -4.1 A) / 5 as the denominator.

[0177] The initial current after AC reversal is the pre-tracking current: -4.3 A is used as the denominator for each measurement, and the measured currents are, for example, -4.3 / -4.3 = 1.0 times, -4.6 / -4.3 = 1.07 times, -4.6 / -4.3 = 1.07 times, -4.2 / -4.3 = 0.98 times, -3.5 / -4.3 = 0.81 times, and in this embodiment, if the magnification of the measured current is equal to or less than a preset arbitrary 15 times, it is determined to be normal.

[0178] An embodiment can be implemented in which a measurement current magnification, for example, a current of 15.0 to 20 times or more that is arbitrarily set, is used as a tracking current, and an alert or automatic shutdown is performed at a predetermined magnification.

[0179] For example, an embodiment may be adopted in which the current at an elapsed time of 128.235 ms is determined to be a current due to a tracking phenomenon with a magnification of 15.2 times (-65.5 A / -4.3 A).

[0180] If this determination is made, the circuit in question will be automatically shut off.

[0181] The current magnification for the automatic shutoff can be arbitrarily set in advance to 15 to 20 times or more, for example, 21 times or more, so that automatic shutoff can be achieved.

[0182] With the average current before tracking after AC reversal as the denominator of each measurement current, and with each measurement current, for example, (-4.3) + (-4.6) + (-4.6) + (-4.2) + (-3.5) / 5 = -3.5 A as the constant denominator, each measurement current becomes, for example, -4.3 / -4.2 = 1.01 times, -4.6 / -4.3 = 1.08 times, -4.6 / -4.2 = 1.08 times, -4.2 / -4.2 = 0.99 times, -3.5 / -4.2 = 0.83 times, and an embodiment can also be made in which the measurement current is determined to be normal when the magnification of the measurement current is equal to or less than a predetermined arbitrarily set 15.0.

[0183] An embodiment can be implemented in which a measurement current magnification, for example, a current of 15.0 to 20 times or more that is arbitrarily set, is used as a tracking current, and an alert or automatic shutdown is performed at a predetermined magnification.

[0184] For example, an embodiment may be adopted in which the current at an elapsed time of 128.235 ms is determined to be a current due to a tracking phenomenon with a magnification of 15.4 times (-65.5 A / -4.2 A).

[0185] If the above judgment is made, the relevant circuit will be automatically shut off.

[0186] The current magnification for the automatic shutoff can be set arbitrarily in advance to 15 to 20 times or more, for example, an embodiment in which automatic shutoff occurs at 21 times or more.

[0187] Current immediately before tracking after AC reversal: -3.5 A is used as the constant denominator, and the respective measured currents are, for example, -4.3 / -3.5 = 1.23 times, -4.6 / -3.5 = 1.31 times, -4.6 / -3.5 = 1.31 times, -4.2 / -3.5 = 1.20 times, -3.5 / -3.5 = 1.0 times, and an embodiment can be made in which the measured current is determined to be normal if the magnification of the measured current is a preset arbitrary 15 times or less.

[0188] An embodiment can be implemented in which a measurement current magnification, for example, a current of 15.0 to 20 times or more that is arbitrarily set, is used as a tracking current, and an alert or automatic shutdown is performed at a predetermined magnification.

[0189] For example, an embodiment may be adopted in which the current at an elapsed time of 128.235 ms is determined to be a current due to a tracking phenomenon with a magnification of 18.7 times (-65.5 A / -3.5 A).

[0190] If the determination is made as described above, the circuit in question can be automatically shut off.

[0191] The current magnification for the automatic shutoff can be arbitrarily set in advance to 15 to 20 times or more, for example, 21 times or more, so that an automatic shutoff can also be achieved in this embodiment.

[0192] With the pre-tracking current, which is the initial current after AC reversal, of 3.7 A as the denominator for each measurement, the measured currents are, for example, 3.7 / 3.7 = 1.0 times, 3.1 / 3.7 = 0.84 times, 4.2 / 3.7 = 1.14 times, 4.0 / 3.7 = 1.08 times, and 4.2 / 3.7 = 1.14 times. An embodiment can be made in which the measured current is determined to be normal if the magnification of the measured current is equal to or less than a preset arbitrary 15 times.

[0193] An embodiment can be implemented in which a measurement current magnification, for example, a current of 15.0 to 20 times or more that is arbitrarily set, is used as a tracking current, and an alert or automatic shutdown is performed at a predetermined magnification.

[0194] For example, an embodiment may be adopted in which the current at an elapsed time of 138.4440 ms is determined to be a current due to a tracking phenomenon with a magnification of 22.1 times (81.9 A / 3.7 A).

[0195] In this case, the circuit may be automatically shut off.

[0196] The current magnification for the automatic shutoff can be arbitrarily set in advance to 15 to 20 times or more, for example, 21 times or more, so that an automatic shutoff can also be achieved in this embodiment.

[0197] With the average current before tracking after AC reversal as the denominator of each measurement current, and each measurement current, for example, (3.7) + (3.1) + (4.2) + (4.0) + (4.2) / 5 = 3.8 A as the denominator of the constant, each measurement current is, for example, 3.7 / 3.8 = 0.96 times, 3.1 / 3.8 = 0.81 times, 4.2 / 3.8 = 1.09 times, 4.0 / 3.8 = 1.04 times, 4.2 / 3.8 = 1.14 times, and in this embodiment, it can be determined that the measurement current is normal when the magnification of the measurement current is equal to or less than 15.0, which is a preset arbitrary value.

[0198] An embodiment can be implemented in which a measurement current magnification, for example, a current of 15.0 to 20 times or more that is arbitrarily set, is used as a tracking current, and an alert or automatic shutdown is performed at a predetermined magnification.

[0199] For example, an embodiment may be adopted in which the current at an elapsed time of 138.444 ms is determined to be a current due to a tracking phenomenon with a magnification of 21.3 times (current 81.9 A / 3.8 A = 21.3 times).

[0200] If the above-mentioned determination can be made, the circuit in question can be automatically shut off.

[0201] The current magnification for the automatic shutoff can be arbitrarily set in advance to 15 to 20 times or more, for example, an embodiment in which automatic shutoff can be performed at 21 times or more.

[0202] With the current immediately before tracking after AC reversal: 4.2 A as the constant denominator, the respective measured currents are, for example, 3.7 / 4.2 = 0.88 times, 3.1 / 4.2 = 0.74 times, 4.2 / 4.2 = 1.0 times, 4.0 / 4.2 = 0.95 times, and 4.2 / 4.2 = 1.0 times, and an embodiment can be made in which the measured current can be determined to be normal if the measured current magnification is 15 times or less, which is a preset arbitrary value.

[0203] An embodiment can be implemented in which a measurement current magnification, for example, a current of 15.0 to 20 times or more that is arbitrarily set, is used as a tracking current, and an alert or automatic shutdown is performed at a predetermined magnification.

[0204] For example, an embodiment may be adopted in which the current at an elapsed time of 138.444 ms is determined to be a current due to a tracking phenomenon with a magnification of 19.5 times (81.9 A / 4.2 A).

[0205] If the above determination can be made, the circuit in question can be automatically shut off.

[0206] The current magnification for the automatic shutoff can be arbitrarily set in advance to 15 to 20 times or more, for example, an embodiment in which automatic shutoff can be performed at 21 times or more.

[0207] The initial current after AC reversal is the pre-tracking current: -0.7 A is used as the denominator for each measurement, and the measured currents are, for example, -0.7-0.7 = 1.0 times, -1.5 / -0.7 = 2.14 times, -1.0 / -0.7 = 1.43 times, -4.7 / -0.7 = 6.71 times, -4.3 / -0.7 = 6.14 times, and an embodiment can be made in which the measured current is determined to be normal if the magnification of the measured current is a preset arbitrary 15 times or less.

[0259] For example, an embodiment may be adopted in which the current at an elapsed time of 8.30 ms is determined to be a current due to a tracking phenomenon with a magnification of 40.9 times, that is, a current of −81.7 A / −2.0 A=a current at an elapsed time of 8.30 ms.

[0260] If the determination is as above, the circuit in question may be automatically shut off.

[0261] The current magnification for the automatic shutoff can be set arbitrarily in advance to 15 to 20 times or more, for example, 21 times or more, so that the automatic shutoff can be performed in this embodiment.

[0262] Current immediately before tracking after AC reversal: -4.1 A is used as the denominator of the constant, and each measured current is, for example, -1.4 / -4.1 = 0.34 times, -0.8 / -4.1 = 0.20 times, -2.0 / -4.1 = 0.49 times, -1.7 / -4.1 = 0.41 times, -4.1 / -4.1 = 1.0 times, and an embodiment can be made in which the measured current is determined to be normal if the magnification of the measured current is a preset arbitrary 15 times or less.

[0263] An embodiment can be implemented in which a measurement current magnification, for example, a current of 15.0 to 20 times or more that is arbitrarily set, is used as a tracking current, and an alert or automatic shutdown is performed at a predetermined magnification.

[0264] For example, an embodiment may be adopted in which the current at an elapsed time of 8.30 ms is determined to be a current due to a tracking phenomenon with a magnification of 19.9 times (-81.7 A / -4.1 A).

[0265] If the determination is made as described above, the circuit in question can be automatically shut off.

[0266] The current magnification for the automatic shutoff can be set arbitrarily in advance to 15 to 20 times or more, for example, 21 times or more, so that the automatic shutoff can be performed in this embodiment.

[0267] For positive current A elapsed time 0.83 ms to 2.49 ms.

[0268] Elapsed time: The positive current A is measured from 0.83 ms to 2.49 ms, and the multiplication factor of each measured current is used.

[0269] For elapsed time of 83 ms to 2.49 A, current is

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

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

[0272] For example, if the negative current A is -1.4 A over 4.15 ms, the initial elapsed time of 4.15 ms is used as the denominator, and the current multiplication factor of the measured current at each measurement time is calculated based on the inversion axis from positive current to negative current, 0 A. An alert can be sent and automatic shutdown can be performed based on a predetermined current multiplication factor. The above may be a negative current that is the inversion of the positive AC current.

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

[0274] For each current multiplier for elapsed times 4.15 ms to 7.47 ms with a negative current A of -1.4 A to 7.47 ms to 4.7 A and an average current of -2.0 A.

[0275] For example, starting from the inversion axis from positive current to negative current of 0 A, the currents of -1.4 A at elapsed time of 4.15 ms to 4.1 A at elapsed time of 7.47 ms can be added together, divided by 5, and the average current of -2.0 A can be used as the denominator to determine spark tracking based on the average current multiplier. An alert can be sent and automatic shutdown can be performed based on a predetermined current multiplier. The above may also be a negative current, which is the inversion of the positive current of the AC current.

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

[0277] An embodiment can be adopted in which current magnification is detected by setting each current to -1.4 A, -0.8 A, -2.0 A, -1.7 A, and -4.1 A, with an average current of -2.0 as the denominator. An embodiment can also be adopted in which an alert is sent and automatic shutdown is performed at a predetermined current magnification. The above may be a negative current, which is the inverse of the positive current of the AC current.

[0278] For example, -4.1 A at an elapsed time of 7.47 ms is detected just before a predetermined arbitrary current multiplier of 15 times or more of the negative current A, and the current multiplier of -81.7 A at an elapsed time of 8.30 ms is set to 19.9 times, and each current A is detected in elapsed time units and the current multiplier is calculated.

[0279] For example, an embodiment can be implemented in which a current value of 15 times or more is detected from the inversion axis of 0 A from positive to negative current, and the current value of -4.1 A at 7.47 ms, which precedes the current value of -81.7 A at 8.3 ms, is used as the denominator, and spark tracking is determined based on the current multiplication factor of each measured current. An alert can be sent at a predetermined arbitrary current multiplication factor, and automatic shutdown can be performed at a current multiplication factor of 20 times or more. The above may also be a negative current, which is the inversion of the positive current of the AC current.

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

[0281] An embodiment can be implemented in which a circuit corresponding to spark tracking is detected and determined at a predetermined current multiplier of 15 times or more, using the negative current elapsed time of 8.30 ms to 9.296 ms, for example, S1 current -1.4 A, S2 current -2.0 A, and S3 current -4.1 A as the denominator. An embodiment can also be implemented in which a circuit corresponding to spark tracking is detected and determined at a predetermined current multiplier of 20 times or more. An example of the current multiplier for each current is shown in FIG. 23.

[0282] The DESCON emergency system can be embodied in such a way that it detects current using the aforementioned current: -1.4 A, current: 2.0 A, and current: -4.1 A as denominators, and determines that spark tracking has occurred when the magnification of each current A is, for example, 15 times or more, a predetermined current magnification. It can also be embodied in such a way that it sends an alert and automatically shuts off when the magnification is 20 times or more.

[0283] For example, a negative current A of -4.3 A over 127.82 ms can be used as the denominator for the initial elapsed time of 127.82 ms, starting from 0 A on the axis of inversion from positive to negative current. The current multiplication factor for the measured current at each measurement time can be calculated to determine spark tracking. An alert can be sent or automatic shutdown can be performed based on a predetermined current multiplication factor. The above may be a negative current that is the inverse of the positive AC current.

[0284] The measured elapsed times were 127.82 ms: -4.3 A, 127.903 ms: -4.6 A, 127.986 ms: -4.6 A, 128.069 ms: -4.2 A, and 128.152 ms: -3.5 A, respectively.

[0285] For each current multiplier from 127.82 ms to 128.152 ms, the average current is -4.2 A, with a negative current A of -4.3 A for an elapsed time of 127.82 ms to -3.5 A for an elapsed time of 128.152 ms.

[0286] For example, starting from the inversion axis of 0 A from positive to negative current, the currents of -4.3 A at elapsed time of 127.82 ms and -3.5 A at elapsed time of 128.152 ms can be added together, divided by 5, and the average current of -4.2 A can be used as the denominator to determine spark tracking using the average current multiplier. An alert can be sent and automatic shutdown can be performed using a predetermined current multiplier. The above may also be a negative current, which is the inversion of the positive current of the AC current.

[0287] The measured values ​​are (elapsed time 128.82 ms: -4.3 A + elapsed time 127.903 ms: -4.6 A + elapsed time 127.986 ms: -4.6 A + elapsed time 128.069 ms: -4.2 A + elapsed time 128.152 ms: -3.5 A) = average current -4.3 A.

[0288] An embodiment can be adopted in which current magnification is detected by using the average current of -4.2 as the denominator for each current of -4.3A, -4.6A, -4.6A, -4.2A, and -3.5A. An alert can be sent and automatic shutdown can be performed at a predetermined current magnification. The above may be a negative current, which is the inverse of the positive current of the AC current.

[0289] For example, -4.1 A at an elapsed time of 7.47 ms, immediately before a predetermined arbitrary negative current A where the current multiplier is 15 times or more, is detected, and the current multiplier of -81.7 A at an elapsed time of 8.30 ms is set to 19.9 times, and each current A is detected in elapsed time units, and the current multiplier is calculated.

[0290] For example, an embodiment can be implemented in which a current value of 15 times or more is detected from the axis of inversion from positive current to negative current, 0 A, and the current value at 8.3 ms elapsed time of -81.7 A is used as the denominator, while the current value at 7.47 ms elapsed time prior to this, -4.1 A, is used as the denominator to determine spark tracking based on the current multiplication factor of each measured current. An alert can be sent at a predetermined current multiplication factor, and automatic shutdown can be performed at a current multiplication factor of 20 times or more. The above may also be a negative current, which is the inverse of the positive current of the AC current.

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

[0292] An embodiment can be implemented in which a circuit corresponding to spark tracking is detected and determined when a predetermined current multiplier of 15 or more is used as the denominator for a negative current elapsed time of 9960 ms to 128.152 ms, for example, a current of -4.3 A, a current of -4.2 A, or a current of -3.5 A. An embodiment can also be implemented in which a predetermined current multiplier of 20 or more is automatically shut off. An example of each current is shown in FIG. 26.

[0293] The DESCON emergency system detects currents of 1545 to 1549 using the aforementioned S1 current: -4.3 A, S2 current: -4.2 A, and S3 current: -3.5 A as denominators, and is characterized by spark tracking and judgment means that sends an alert when the magnification of each current A is, for example, a predetermined arbitrary current magnification of 15 times or more, and by control means that automatically shuts off when it is 20 times or more.

[0294] The device is characterized by a means for determining spark tracking by calculating a current multiplication factor for the measured current at each measurement time, using, for example, 3.7 A at the elapsed time of 138.029 ms for a positive current A, with the initial elapsed time of 138.029 ms (3.7 A) as the denominator, starting from 0 A on the axis of inversion from positive current to negative current, and by transmitting an alert and automatically shutting down the device at a predetermined current multiplication factor. The device may also be characterized by a means for determining spark tracking by using a negative current that is the inverse of the positive current of the AC current.

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

[0296] S2: For positive current A, the average current is 3.8 A for elapsed time 138.029 ms: 3.7 A to 138.361 ms: 4.2 A. For each current multiplier for elapsed time 138.029 ms to 138.361 ms.

[0297] For example, the device is characterized by a means for determining spark tracking by multiplying the average current by 5, taking the average current of 3.8 A as the denominator, and sending an alert and automatically shutting down the device at a predetermined current multiplier.The above may be a negative current that is the inverse of the positive current of the AC current.

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

[0299] The device is characterized by a determination means for detecting a current magnification of each current of 3.7 A, 3.1 A, 4.2 A, 4.0 A, and 4.2 A with an average current of 3.8 as the denominator, and by a means for sending an alert and automatically shutting off the power supply when a predetermined current magnification is reached. The above may be a negative current, which is the inverse of the positive current of the AC current.

[0300] For example, 4.2 A at an elapsed time of 138.361 ms is detected immediately before a predetermined arbitrary positive current A with a current multiplier of 15 times or more, and the current multiplier of 81.9 A at an elapsed time of 138.444 ms is set to 19.5 times. Each current A is detected in elapsed time units, and the current multiplier is calculated.

[0301] For example, the device is characterized by a means for detecting a current value of 15 times or more of the inversion axis 0A from positive current to negative current, determining spark tracking based on the current multiplication factor of each measured current, using the denominator of 4.2A at elapsed time 138.361 ms before 81.9A at elapsed time 138.444 ms, and sending an alert when the current multiplication factor is arbitrarily set in advance, and automatically shutting off when the current multiplication factor is 20 times or more. The above may also be a negative current that is inverted from the positive current of the AC current.

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

[0303] The device is characterized by a means for detecting and determining the circuit in the system where spark tracking occurs when the current multiplier is 15 times or more, as determined in advance, using the denominators of the positive current elapsed time of 138.029 ms: 3.7 A to 138.361 ms, for example, S1 current 3.7 A, S2 current 3.8 A, and S3 current 4.2 A, and by a means for automatically shutting off the circuit when the current multiplier is 20 times or more, as determined in advance. Examples of the current multipliers for the S1, S2, and S3 currents are shown in Figures 29 and 30.

[0304] The DESCON emergency system detects currents of 1668 to 1690 using the S1 current of 3.7A, S2 current of 3.8A, and S3 current of 4.2A as the denominators, and is characterized by a spark, tracking, and judgment means that sends an alert when the magnification of each current A is, for example, 15 times or more, a current magnification that is arbitrarily determined in advance, and a control means that automatically shuts off the circuit when it is 20 times or more.

[0305] For example, when the negative current A is −0.7 A over 147.657 ms, the initial elapsed time is set to −0.7 A at 147.657 ms, based on an inversion axis from positive current to negative current of 0 A. The device is characterized by a means for calculating a current multiplier for the measured current at each measurement time, using the initial elapsed time of 147.657 ms as the denominator, to determine spark tracking, and a means for transmitting an alert and automatically shutting down the device at a predetermined current multiplier. The above may be a negative current that is the inverse of the positive current of the AC current.

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

[0307] S2: For negative current A, the average current is -2.4A from elapsed time 147.657ms -0.7A to 147.989ms -4.3A. For each current multiplier from elapsed time 147.657ms to 147.989ms.

[0308] For example, the device is characterized by a means for determining spark tracking by multiplying the average current by 5, taking the average current of -2.4 A as the denominator, and sending an alert and automatically shutting down the device at a predetermined current multiplier.The above may be a negative current that is the inverse of the positive current of the AC current.

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

[0310] The device is characterized by a determination means for detecting a current magnification of each current of -0.7 A, -1.5 A, -1.0 A, -4.7 A, and -4.3 A with an average current of -2.4 as the denominator, and by a means for sending an alert and automatically shutting off the power supply when a predetermined current magnification is reached. The above may be a negative current, which is the inverse of the positive current of the AC current.

[0311] For example, -4.3 A at an elapsed time of 147.989 ms is detected immediately before a predetermined arbitrary negative current A with a current multiplier of 15 times or more, and the current multiplier of -33.3 A at an elapsed time of 148.072 ms is set to 7.7 times. Each current A is detected in elapsed time units, and the current multiplier is calculated.

[0312] For example, the device is characterized by a means for detecting a current value of 15 times or more of the inversion axis 0A from positive current to negative current, and determining spark tracking based on the current multiplication factor of each measured current, using the current value -4.3A at elapsed time 147.989 ms, which is the current value -33.3A at elapsed time 148.072 ms before, as the denominator, and by sending an alert when the current multiplication factor is any predetermined value, and by automatically shutting down when the current multiplication factor is 20 times or more. The above may also be a negative current that is the inversion of the positive current of the AC current.

[0313] The measured values ​​are (elapsed time 147.657 ms: -0.7 A + elapsed time 147.740 ms: -1.5 A + elapsed time 147.823 ms: -1.0 A + elapsed time 147.906 ms: -4.7 A + elapsed time 147.989 ms: -4.3 A) / 5 = average current -2.4 A.

[0314] The device is characterized by a means for detecting and determining a circuit in a system where spark tracking occurs when a predetermined current multiplier of 15 times or more is set using the current value of the negative current elapsed time from 148.072 ms to 149.898 ms as the denominator, and by a means for automatically shutting off a circuit when a predetermined current multiplier of, for example, 20 times or more is set. Examples of current multipliers for the currents S1, S2, and S3 are shown in Figures 33 and 34.

[0315] The DESCON emergency system detects currents of 100 to 113 using the above current value as the denominator, and is characterized by a spark tracking judgment means that sends an alert when the magnification of each current A is, for example, 15 times or more, a current magnification that is arbitrarily determined in advance, and a control means that automatically shuts off the system when the magnification is 20 times or more.

[0316] The device is characterized by a means for determining spark tracking by calculating a current multiplication factor of the measured current at each measurement time, for example, using 4.6 A at 158.530 ms for the elapsed time of positive current A, for example, from 0 A on the axis of inversion from positive current to negative current, with the initial elapsed time of 4.6 A at 158.530 ms as the denominator, and by transmitting an alert and automatically shutting down the device at a predetermined current multiplication factor. The device may also be characterized by a means for determining spark tracking by calculating a current multiplication factor of the measured current at each measurement time, for example, using 4.6 A at 158.530 ms as the denominator, for example, using 0 A on the axis of inversion from positive current to negative current.

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

[0319] For example, the device is characterized by a means for determining spark tracking by multiplying the average current by 5, taking the average current of 4.4 A as the denominator, and sending an alert and automatically shutting down the device at a predetermined current multiplier.The above may be a negative current that is the inverse of the positive current of the AC current.

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

[0321] The device is characterized by a determination means for detecting a current magnification of each current of 4.6 A, 4.4 A, 4.3 A, 4.1 A, and 4.8 A with an average current of 4.4 A as the denominator, and by a means for sending an alert and automatically shutting off the power supply when a predetermined current magnification is reached. The above may be a negative current, which is the inverse of the positive current of the AC current.

[0322] For example, 4.8 A at an elapsed time of 158.862 ms is detected immediately before a predetermined arbitrary positive current A with a current multiplier of 15 times or more, and the current multiplier of 56.4 A at an elapsed time of 158.945 ms is set to 11.8 times. Each current A is detected in elapsed time units, and the current multiplier is calculated.

[0323] For example, the device is characterized by a means for detecting a current value of 15 times or more of a current multiplication factor on an inversion axis from positive current to negative current of 0 A, and determining spark tracking based on the current multiplication factor of each measured current, using the denominator of 56.4 A at an elapsed time of 158.945 ms and 4.8 A at the previous elapsed time of 158.862 ms, and sending an alert when the current multiplication factor is arbitrarily set in advance, and automatically shutting off when the current multiplication factor is 20 times or more. The above may also be a negative current that is the inversion of the positive current of the AC current.

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

[0325] The device is characterized by a means for detecting and determining a circuit in a system where spark tracking occurs when a predetermined current multiplier of 15 times or more is set using the current value of the negative current between 158.945 ms and 160.190 ms as the denominator, and a means for automatically shutting off a circuit where a predetermined current multiplier of, for example, 20 times or more is set. Examples of current multipliers for each current are shown in Figures 38 and 39.

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

[0327] For example, when the negative current A is −4.9 A over an elapsed time of 167.162 ms, the current multiplication factor of the measured current at each measurement time is calculated using the initial elapsed time of 167.162 ms, −4.9 A, as the denominator, starting from 0 A on the axis of inversion from positive current to negative current, to determine spark tracking, and the device is characterized by a means for transmitting an alert and automatically shutting down the device at a predetermined arbitrary current multiplication factor.The above may be a negative current that is the inverse of the positive current of the AC current.

[0328] The measured elapsed times were 167.162 ms: -4.9 A, 167.245 ms: -4.7 A, 167.328 ms: -4.9 A, 167.411 ms: -5.4 A, and 167.494 ms: -4.7 A.

[0329] S2: For the average current of -4.9A from elapsed time 167.162ms -4.9A to 167.494ms -4.7A for negative current A. For each current multiplier from elapsed time 167.162ms to 167.494ms.

[0330] For example, the device may be characterized by a means for determining spark tracking based on an average current multiplication factor, such as adding a current of −4.9 A at an elapsed time of 167.162 ms to a current of 4.7 A at an elapsed time of 167.494 ms starting from 0 A on the axis of inversion from positive current to negative current, dividing the sum by 5, and using an average current of −4.9 A as the denominator, and by transmitting an alert and automatically shutting down the device at a predetermined current multiplication factor. The above may also be a negative current that is the inverse of the positive current of the AC current.

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

[0332] The device is characterized by a determination means for detecting a current magnification of each current of -4.9 A, -4.7 A, -4.9 A, -5.4 A, and -4.7 A with an average current of -4.9 A as the denominator, and by a means for sending an alert and automatically shutting off the power supply at a predetermined current magnification. The above may be a negative current that is the inverse of the positive current of the AC current.

[0333] For example, -4.9 A at an elapsed time of 167.162 ms, immediately before a predetermined arbitrary current multiplier of 15 times or more of the negative current A, is detected, and the current multiplier of -95.3 A at an elapsed time of 167.660 ms is set to 20.3 times, and each current A is detected in elapsed time units to calculate the current multiplier.

[0334] For example, the device detects current values ​​with a current multiplier of 15 or more from the 0A axis, which is the inversion axis from positive to negative current. Using the current value at 167.660 ms (-95.3A) and the current value at 167.494 ms (-4.7A) as the denominator, the device determines spark tracking based on the current multiplier of each measured current. The device also features a means for sending an alert at a predetermined current multiplier and automatically shutting off at a current multiplier of 20 or more. The device may also be a negative current, which is the inverse of the positive AC current. 2) The measured elapsed times are as follows: 4.15 ms: -1.4A, 4.98 ms: -0.8A + 5.81 ms: -2.0A + 6.64 ms: -1.7A + 7.47 ms: -4.1A.

[0335] The device is characterized by a means for detecting and determining whether a circuit in a system where spark tracking occurs has a predetermined current multiplication factor of 15 or more, using the current value of the negative current during the elapsed time of 8.30 ms to 9.296 ms as the denominator, and by a means for automatically shutting off a circuit where a predetermined current multiplication factor of, for example, 20 or more has been determined. Examples of current multiplication factors for the currents S1, S2, and S3 are shown in Figures 42 and 43.

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

The device is also characterized by a means for transmitting an alert and automatically shutting down the device at a predetermined current multiplication factor. The above may be a negative current that is the inverse of the positive current of the AC current.

[0338] The measured elapsed times were 177039 ms: 2.9 A, 177.122 ms: 4.5 A, 177.205 ms: 3.9 A, 177.288 ms: 3.6 A, 177.371 ms: 3.6 A, and 177.454 ms: 8.9 A, respectively.

[0339] S2: For positive current A, the average current is 4.6A, with 2.9A for elapsed time 177.039ms to 8.9A for elapsed time 177.454ms. For each current multiplier for elapsed time 177.039ms to 177.454ms.

[0340] For example, the device is characterized by a means for determining spark tracking by multiplying the average current by 6, taking the average current of 4.6 A as the denominator, and sending an alert and automatically shutting down the device at a predetermined current multiplier.The above may be a negative current that is the inverse of the positive current of the AC current.

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

[0342] The device is characterized by a determination means for detecting a current magnification of each current of 2.9 A, 4.5 A, 3.9 A, 3.6 A, 3.6 A, and 8.9 A with an average current of 4.6 A as the denominator, and by sending an alert and automatically shutting off the power supply when a predetermined current magnification is reached. The above may be a negative current, which is the inverse of the positive current of the AC current.

[0343] For example, 8.9 A at an elapsed time of 177.454 ms is detected immediately before a predetermined arbitrary positive current A with a current multiplier of 15 times or more, and a current multiplier of -81.7 A at an elapsed time of 177.454 ms is set to 7.6 times. Each current A is detected in elapsed time units, and the current multiplier is calculated.

[0344] For example, the device is characterized by a means for detecting a current value of 15 times or more on an inversion axis from positive current to negative current of 0A, and determining spark tracking based on the current multiplication factor of each measured current, using the current value of 67.2A at 177.537 ms and the current value of 8.9A at 177.454 ms before that as the denominator, and by sending an alert when the current multiplication factor is any predetermined value, and by automatically shutting down when the current multiplication factor is 20 times or more. The above may also be a negative current that is the inversion of the positive current of the AC current.

[0345] The measured elapsed times were 177039 ms: 2.9 A, 177.122 ms: 4.5 A, 177.205 ms: 3.9 A, 177.288 ms: 3.6 A, 177.371 ms: 3.6 A, and 177.454 ms: 8.9 A, respectively.

[0346] The device is characterized by a means for detecting and determining whether a circuit in a system where spark tracking occurs has a predetermined current multiplication factor of 15 or more, using the current value of the negative current during the elapsed time of 8.30 ms to 9.296 ms as the denominator, and by a means for automatically shutting off a circuit where a predetermined current multiplication factor of, for example, 20 or more has been determined. Examples of current multiplication factors for the currents S1, S2, and S3 are shown in Figures 46 and 47.

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

[0348] The Joule heat program in the DESCON emergency system detects Joule heat by installing temperature sensors for each circuit of fittings, terminals, etc. on low-voltage lighting, power distribution boards, main lines, electric lights, power distribution boards, electric lights, power control panels, etc., and installing temperature sensors in each panel, or on fittings, outlets, load equipment, etc. on main lines, electric wires, terminal devices, etc., and installing temperature sensors for each circuit on the distributor remote panel. If the allowable temperature of each cable exceeds a predetermined warning temperature, an alert signal will be sent to the relevant parties, and if the warning temperature remains at the predetermined temperature for a set time or exceeds a predetermined alert temperature, the relevant circuit will be automatically shut off.

[0349] The DESCON Emergency System detects Joule heat generated in the relevant parts of panels and connecting devices such as cubicles, distribution boards, control panels, terminal outlets, freezers, refrigerators, conveyors, welders, movable control panels, PCs, servers, network equipment, inspection operator equipment, etc. in homes, apartments, offices, commercial facilities, hospitals, hotels, laboratories, trade fairs, exhibition halls, data centers, logistics centers, warehouses, factories, construction sites, airports, ships, substations, power plants, solar power generation, wind power generation, etc., when, for example, power cables, whether fixed or temporary, movable or mobile, are compressed, pulled, bent at a sharp angle by a heavy object, the conductive area through which the current flows is deformed, narrowed, bent, pulled, pressure pulsed, etc., or broken, reduced, or poor contact occurs in the relevant parts, and detects a temperature that is arbitrarily set in advance relative to the allowable temperature of the electrical material. For example, 1 to n Joule heat detection devices can be installed in trunk lines, wiring, cables, etc. other than each of the panels, at any position where Joule heat may be generated in the trunk lines, wiring, cables, etc. due to, for example, a narrowing of the conduction area due to pressure, bending, pulling, etc., or a partial disconnection, and the Joule heat detection device is installed in each component such as the trunk lines, wiring, cables, etc. on the panel or other than the panel, and when the temperature of the abnormal temperature conduction due to a disconnection or poor contact of the power cable of each piece of equipment rises and reaches a preset allowable temperature, an alert of a warning temperature is sent by voice, numerical value, and image to the PC, tablet, or smartphone of the relevant person to notify them, and an alert sound will sound until the relevant person checks and resets, preventing the relevant person from failing to check.

[0350] The summary of the DESCON Emergency System is that the maximum allowable temperature of KIV cables, CV cables, etc. is set as a caution temperature or alarm temperature in advance, and alerts are sent in real time to the PC tablets, smartphones, etc. of the relevant parties using voice, images, numerical values, etc., to automatically shut off breakers, etc. for the distribution boards, distribution boards, control panels, main lines, circuits, etc. of the relevant equipment, or to the relevant terminals of the relevant equipment, such as products, manufacturing, etc. using computer programs such as AI and IoT, logistics centers, large freezers, refrigerators, etc., commercial facilities where many people gather, terminal buildings, hotels, etc., lighting, elevators, etc., data centers for important data, research test results, etc., infrastructure substations, etc., various relevant facilities and electrical equipment, etc. for transportation trains, ships, etc. When terminal devices such as those for program control and control of end facilities and electrical equipment are shut down by a predetermined program, the system is composed of remote devices for each system such as distribution boards, distribution boards, control panels, main lines, circuits, breakers, etc., a cloud server, a LAN, etc., and the remote devices for each system, such as the relevant distribution boards, distribution boards, control panels, etc., send a signal to the protection stop device using an emergency response protection program via the cloud server, LAN, etc., and the control equipment, etc., is shut down collectively or selected terminal devices, etc. by a predetermined program, and an embodiment can be made in which the stop function control means and the stop signal can be confirmed normally and safely.

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

[0352] For example, it detects abnormal temperature rises caused by Joule heat due to disconnections or poor contact of power cables in refrigerators, washing machines, electrical appliances, etc. in offices, homes, factories, etc.

[0353] For example, it detects abnormal temperature rises caused by Joule heat due to disconnections or poor contact of power cables in movable control panels in factories, laboratories, data centers, servers, etc.

[0354] For example, it detects abnormal temperature rises caused by Joule heat due to disconnections or poor contact in the power cables of conveyors at logistics centers.

[0355] For example, abnormal temperature rises due to Joule heat caused by disconnection of the power cable of a welder device at a construction site or poor contact are detected.

[0356] For example, abnormal temperature rises caused by Joule heat due to disconnection or poor contact of the power cable in a building cubicle are detected.

[0357] The DESCON emergency system can be configured, for example, as follows: when the installed current value is applied, each panel for each system, as well as electrical equipment, electrical devices, terminal equipment, etc., are operated and stopped as follows:

[0358] Power is supplied from the substation equipment and cubicles to, for example, electric lights and power panels via main CV cables. The CV cables are connected from outside the panel to the terminal block of the main breaker with bolts and screws and tightened with a specified tightening torque strength.

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

[0360] The wiring branches from the secondary terminal block of each branch breaker to the terminal block of the distribution board via a KIV cable, or via a magnetic switch, and is connected with bolts and screws and tightened with a specified tightening torque strength.

[0361] The terminal block of the distribution board is connected to each load equipment outside the board, for example, by a CV cable.

[0362] The DESCON emergency system measures Joule heat generated by the current flowing through the electrical equipment, etc. due to looseness or gaps in the screws, bolts, terminal connectors, etc. of the connecting fittings on each panel, etc., by attaching a temperature sensor to each circuit, for example, CV cable, KIV cable, etc., and inputting the detected temperature of the wiring or copper bar, etc., and when the temperature reaches a preset temperature, for example, it determines that Joule heat has been generated in the connection part of the relevant terminal, etc.

[0363] Power is supplied from the substation equipment / cubicle to the main line, such as a CV cable, which is connected with bolts and screws to the primary terminal block of the main breaker of the electric light / power panel, and the CV cable alarm temperature is monitored with an electric wire or copper bar temperature detector connected to a temperature sensor installed on the CV cable at the connection point, which is tightened with a specified tightening torque strength.

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

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

[0366] The DESCON Emergency System has a maximum operating temperature of 60 degrees for the IV-KIV core wire and insulator, which can be set in advance. For example, if the system detects a temperature of -5 degrees, or 55 degrees, it will be considered a warning temperature and an audio alert will be sent to relevant parties via PC, tablet, smartphone, etc. with the relevant information, such as the customer name, building name, facility name, location, light, type of power, and if it detects the arbitrarily set temperature of 60 degrees, it will be considered an alarm temperature and the relevant circuit will be automatically shut off. An alert will be sent to relevant parties via PC, tablet, smartphone, etc. with the relevant information, such as the customer name, building name, facility name, location, light, type of power, audio, numbers, images, etc., and the breakers for the distribution board, distribution board, control panel, main line, circuit, etc. of the relevant equipment will be automatically shut off. When the terminal equipment, etc., for program control or control of the relevant terminal facilities, electrical equipment, etc. is shut down by a predetermined program, an embodiment can be made in which the remote devices, etc. for each system, such as distribution boards, distribution boards, control panels, main lines, circuits, breakers, etc., send a stop signal to the protection stop device via a cloud server, LAN, etc., by an emergency response protection program, thereby safely and reliably realizing the stop function and the function of confirming the stop signal.

[0367] Furthermore, for example, the allowable temperature of 60 degrees for the maximum operating temperature core wire and insulator of KIV, VVF, VCT, etc. is set arbitrarily in advance. If the allowable temperature of 60 degrees for the maximum operating temperature core wire and insulator is exceeded, for example, to an arbitrarily set 70 degrees, for example, for 30 minutes, it is determined to be dangerous due to Joule heat generation and the relevant circuit is automatically shut down. At the same time, an alert is sent to the relevant parties via a PC, tablet, smartphone, etc., with, for example, the customer name, building name, facility name, location, light, type of power source, voice, numerical value, image, etc., and the relevant terminal equipment, terminal equipment for program control, control, etc. of the electrical equipment, etc. is shut down by a predetermined program. In an embodiment, the remote device of the relevant distribution board, distribution board, control panel, main line, circuit, breaker, etc., can be connected to a remote device for each system, a cloud server, LAN, etc., via an emergency response protection program, and the remote device of the relevant distribution board, distribution board, control panel, etc. sends a stop signal to the protection stop device to safely and reliably shut down the equipment, and also the stop signal can be confirmed.

[0368] The maximum operating temperature of the HIV indoor 600V core wire and the allowable temperature of the insulator is 75 degrees, which can be set in advance. If this temperature is detected, an alarm temperature will be generated and an alert will be sent to the relevant parties via PC, tablet, smartphone, etc., with the customer name, building name, facility name, location, voice, numbers, images, etc.

[0369] The maximum allowable temperature of 75 degrees for the core wire and insulator for HIV, etc. is arbitrarily set in advance, for example, if the maximum allowable temperature of the core wire and insulator exceeds 75 degrees, which is arbitrarily set in advance, for example, 75 degrees Celsius and reaches 76 degrees Celsius, it is considered a caution current, and an alert is sent to the relevant parties via PC, tablet, smartphone, etc. using voice, numbers, images, etc., for example, with the customer name, building name, facility name, location, light, type of power source, voice, voice, numbers, images, etc. Furthermore, for example, if a temperature of, say, 76 degrees, which has been arbitrarily set in advance, is judged to be dangerous due to Joule heat generation after 30 minutes, an alarm temperature will be issued and the relevant circuit will be automatically shut off. At the same time, an alert will be sent to the relevant parties via a PC, tablet, smartphone, etc., with, for example, the customer name, building name, facility name, location, light, type of power, voice, sound, numerical value, image, etc., and the relevant terminal equipment, terminal equipment for program control of electrical equipment, etc. will be shut down by a predetermined program. In an embodiment, the remote devices for each system, such as distribution boards, distribution boards, control panels, main lines, circuits, breakers, etc., will send a stop signal to the protection stop device via a cloud server, LAN, etc., by an emergency response protection program, thereby realizing the function of safely and reliably shutting down the equipment, and also realizing the function of confirming the stop signal.

[0370] The maximum operating temperature of the core wire and insulator of a 600V CV indoor unit is 90 degrees, and can be set arbitrarily in advance. For example, if the maximum operating temperature of 90 degrees is detected, or if the arbitrarily set maximum operating temperature of 90 degrees is exceeded for 30 minutes, it is determined that a danger exists due to Joule heat generation and an alarm temperature is triggered, the relevant circuit is automatically shut off, and an alert is sent to the relevant parties via a PC, tablet, smartphone, etc. using voice, numbers, images, etc., such as the customer name, building name, facility name, location, light, type of power, voice, numbers, images, etc., and the relevant terminal equipment, terminal equipment for program control, etc. of electrical equipment, etc. is shut down by a predetermined program. In an embodiment, the distribution board, distribution board, control panel, main line, circuit, breaker, etc. are connected to remote devices, etc. by system, via a cloud server, LAN, etc., by an emergency response protection program, and the remote device of the relevant distribution board, distribution board, control panel, etc. sends a stop signal to the protection stop device to safely and reliably shut down the unit, and an embodiment can also be configured to confirm the stop signal.

[0371] The DESCON Emergency System also sends audio, numerical and image alerts to the PCs, tablets and smartphones of those involved, and notifies them. The alert ringtone continues to ring until the relevant parties confirm and reset the system. In addition, the system sends multiple emails in succession and the ringtone continues to ring, preventing those involved from missing out on checking.

[0372] The DESCON Emergency System sets the maximum allowable temperature of KIV cables, CV cables, etc. as a caution temperature and an alarm temperature in advance, and sends alerts in real time to the PC tablets, smartphones, etc. of the relevant parties using audio, images, numerical values, etc., and automatically shuts off breakers, etc. on the distribution boards, distribution boards, control panels, main lines, circuits, etc. of the relevant equipment, or automatically shuts off the relevant terminal equipment, electrical equipment, etc. of various relevant equipment, such as products, manufacturing, etc., logistics centers, large freezers, refrigerators, etc., commercial facilities where many people gather, terminal buildings, hotels, etc., data centers for important data, research test results, etc., infrastructure substations, etc., transportation trains, ships, etc. When terminal devices such as program control and control are shut down by a predetermined program, the system is composed of remote devices for each system such as distribution boards, distribution boards, control panels, main lines, circuits, breakers, etc., a cloud server, a LAN, etc., and an emergency response protection program is used to send a signal from the remote devices such as the relevant distribution boards, distribution boards, control panels, etc. to the protection stop device, thereby realizing the function of shutting down all or selected terminal devices such as control by a predetermined program, thereby realizing a normal and safe stop function and also realizing the function of being able to confirm the stop signal.

[0373] Regarding the equations for maximum allowable temperatures, caution temperatures, alarm temperatures, and automatic shutoff for each type of electrical wire. Regarding the relationship between electrical wire type, use, maximum allowable temperatures, caution temperatures, alarm temperatures, and automatic shutoff.

[0374] The Joule heat program in the DESCON emergency system can be embodied in such a way that it can determine an alarm temperature when, for example, a distribution board, distribution board, junction box, connection device, terminal fixture, connection equipment, terminal, electrical equipment / tool, cable, electric wire, etc., exceeds the allowable temperature by +10 to +15 degrees for, for example, 15 minutes, or exceeds the allowable temperature by 15 degrees, based on allowable temperatures for cables, electric wires, etc. by temperature, such as IV / KIV allowable temperature 60 degrees, VVF allowable temperature 60 degrees, VCT allowable temperature 60 degrees, HIV allowable temperature 75 degrees, CV allowable temperature 90 degrees, and MLFC allowable temperature 90 degrees, etc., which are arbitrarily determined in advance. In this case, the corresponding cable, circuit, connection device, terminal, etc. can be automatically shut off.

[0375] Furthermore, the system sends alerts to the relevant parties' PCs, tablets, smartphones, etc. with, for example, the customer name, building name, facility name, location, light, type of power, voice, audio, numbers, images, etc., and continuously notifies them of the alarm temperature and automatic shutdown, preventing them from failing to check.The DESCON Emergency System can be embodied in such a way that it detects and judges the risk of spark, short circuit, tracking, etc. occurring when Joule heat is generated and the connecting fittings, terminals, wires, circuits, etc. exceed the allowable temperature, causing the coating material to burn or melt, etc., causing the temperature of the relevant wires, circuits, etc. to rise due to Joule heat, melting the coating material of the electrical resistance of the relevant cables, wires, circuits, etc.

[0376] For reference, conventional thermal conduction breakers operate in response to an overcurrent value A or the like, and the temperature of the relevant circuit, connecting fittings' screws, bolts, terminals, etc. rises over time, and the protective function of the thermal conduction breaker is activated and cut off at the set temperature, time, etc., thereby protecting the relevant circuit, connecting fittings, etc. from electrical burnout, etc., through its overcurrent prevention function.

[0377] An electronic breaker is set in advance to a safe allowable current value A for the relevant circuit, etc., based on standards for the allowable current value of the relevant circuit and connecting fittings such as screws, bolts, and terminals, and when the set current value A is reached, the thermal conduction breaker, which has a protective function, activates and cuts off the current, thereby protecting the relevant circuit, connecting fittings, etc. from electrical burnout and other damage through its overcurrent prevention function.The thermal conduction breaker's protective function is activated when the temperature rises, and the electronic breaker's protective function is also activated when the allowable current value A is reached.However, conventionally, there is no function to instantly detect spark tracking, which occurs when the insulating coating of the anode and cathode wires of the current shorts out the relevant wires, causing a tracking phenomenon at 1 sec / 12,000 or 83 μsec.

[0378] The DESCON emergency system is an ammeter (CT) that detects current A in the relevant circuits, fittings, terminals, etc. of electrical equipment. It converts the current at 83 μsec, which is a common multiple of the power frequency, such as 50 Hz or 60 Hz, for example, by dividing one second by 12,000 times, into voltage, and then converts the real analog voltage into an analog-to-digital converter (ADC) that converts it into a real analog voltage using, for example, a microcomputer, etc., to detect currents that are 15 to 90 times the normal current of the spark tracking phenomenon caused by Joule heat from the relevant panel circuits, fittings such as screws, bolts, and terminals, cables, electric wires, terminal load equipment, etc., that exceed the allowable temperature of the insulating coating of the anode and cathode electric wires and melt, and then detects the instantaneous current of the 83 μsec. By detecting the current, for example, a normal current of 83 μsec is used as the denominator, and an alert is sent to the relevant person's PC, smartphone, tablet, etc. with, for example, the customer name, building name, facility name, location, light, type of power, voice, sound, numbers, images, etc. at a multiplier of, for example, 15 times or more of the normal current that has been arbitrarily set in advance. The relevant circuit, connecting fittings, cables, electric wires, terminal load equipment, etc. are then automatically shut off at, for example, 20 times or more of the arbitrarily set normal current, and the system prevents serious electrical burns and electrical fires such as melting of the insulating coating of the electric wire due to high temperatures caused by Joule heat, short sparks, and tracking phenomena, which has a great effect on preventing personal injury accidents both socially, economically, and at home.

[0379] The current conduction area of ​​the cables and wiring materials can become narrow due to factors such as screws and terminals on connecting hardware in distribution boards, panel boards, control panels, terminal load equipment, etc., looseness and gaps in circuits, the passage of heavy objects such as cables and wires installed in floor-buried piping, and tensile forces at connections, and since current flows at a constant allowable current value, if there is no conduction area for a specified circuit, cable, wire, etc., the thermal resistance increases in proportion to the current, and Joule heat is generated in proportion to the elapsed time, and if the allowable temperature of each wire is exceeded, the insulating coating of the anode and cathode of the electricity will melt and burn, causing the circuit or wire to short out and spark. <Joule heat detection device in DESCON emergency system> One to n Joule heat detection devices are installed arbitrarily on temporary, movable, mobile, etc. power cables of cubicles, distribution boards, panel boards, control panels, terminal outlets, freezers, refrigerators, conveyors, welders, movable control panels, PCs, servers, network equipment, inspection operator equipment, etc. in homes, apartments, offices, commercial facilities, hospitals, hotels, laboratories, trade fairs, exhibition halls, data centers, logistics centers, warehouses, factories, construction sites, etc.

[0380] It detects temperature rises caused by broken power cables, poor contact, etc., and if an abnormal temperature is detected, it automatically shuts off the relevant circuit.

[0381] Alerts are sent in real time to relevant parties' PCs, tablets, smartphones, etc. using audio, images, numbers, etc.

[0382] The Joule heat detection system in the DESCON Emergency System detects electrical Shore heat due to the generation and rise of electrical resistance heat caused by a decrease in the area of ​​electrical conduction while the current value remains constant due to looseness or gaps in the connecting fittings of panels, circuits, etc., resulting in a decrease in the area of ​​electrical conduction. Temperature sensors are installed for each circuit on connecting fittings, terminals, etc. of low-voltage lights, power distribution panels, main lines, electric lights, power distribution panels, electric lights, power control panels, etc., and temperature sensors are installed inside each panel or near connecting fittings, outlets, load equipment, etc. of main lines, electric wires, terminal devices, etc., and temperature sensors for each circuit are installed in distributors and remote panels.If the allowable temperature of each cable exceeds a predetermined warning temperature, a warning signal will be sent to alert relevant parties, and if the warning temperature remains at the predetermined temperature for a set time or exceeds a predetermined alert temperature, the relevant circuit will be automatically shut off.

[0383] For example, in the case of high voltage and low voltage lights, power distribution panels, main lines, lights, power distribution panels, lights, power control panels, light and power terminal equipment, electrical equipment and fixtures and terminal equipment, control panels for electrical equipment, remote panels, etc. (sometimes referred to as "panels" in this specification), the primary wiring and the screws, bolts, terminal connectors, and wiring at the connection parts of the connecting metal fittings expand due to a rise in temperature of the wiring when a current is passed through the wiring, and contract due to a drop in temperature after a power outage. The phenomena of expansion of the wiring, contraction during a power outage, etc. are proportional to the time and the number of years that have passed, and the wiring at the connection parts of the screws, bolts, terminals, etc. loosen, gaps occur, etc., and as a result, poor connections of the wiring and connecting fittings cause the electrical materials and connecting devices through which current flows to decrease in their predetermined size, for example, and although the current value is constant, the contact conduction area decreases and the temperature of the thermal resistance value increases, Joule heat is generated and the temperature rises, and the connecting fittings, wiring, etc. reach such a high temperature that the allowable temperature of the insulating coating of each cable, wiring, etc. is exceeded, causing burning and an electrical fire accident.

[0384] The maximum allowable temperature for each type of cable, wire, etc. can be arbitrarily set in advance as a temperature for Joule heat, such as a caution temperature, an alarm temperature alert, or an automatic shutoff temperature.

[0385] The DESCON emergency system is a system that installs, for example, one to N temperature sensors on each cable for inside the panel, for example, a KIV cable with a maximum allowable temperature of 60 degrees, and outside the panel, for example, a CV cable with a maximum allowable temperature of 90 degrees. The temperature sensor measures, for example, the temperature of a KIV cable, which is arbitrarily set in advance, against the looseness, gaps, etc. of the screws, bolts, terminals, etc., which causes a decrease in the current conduction area due to poor wiring connections, resulting in Joule heat, which rises the temperature of the cable, and before the insulating coating material burns out, for example, a pre-set K For IV cables, an alert is sent when the maximum allowable temperature is 60 degrees, or the previously set ``safe allowable temperature of 60 degrees'' for the cable in question, as a ``warning temperature.'' The ``alarm temperature'' is a previously set value, for example ``maximum allowable temperature + 5 degrees'' = ``65 degrees,'' and if it exceeds a previously set value, for example 65 degrees, and reaches 66 degrees, it becomes a ``warning current,'' and an alert is sent to the relevant parties via PC, tablet, smartphone, etc. using audio, numbers, images, etc., with, for example, the customer name, building name, facility name, location, light, type of power source, audio, numbers, images, etc. Furthermore, if a temperature such as "65 degrees" continues for "more than one minute" or rises above "65 degrees," the system will "automatically shut off" the circuit in question as an "alarm temperature," and send an audio, numerical, image, etc. alert to the relevant person's PC, tablet, smartphone, etc. to notify them of the relevant information, such as the customer name, building name, facility name, location, light, type of power, capacity, electrical equipment at the system terminal, and name of load equipment, and the alert ringtone will continue to sound until the relevant person checks and resets the system, preventing the relevant person from missing out on checking.

[0386] The summary of the DESCON Emergency System is that the maximum allowable temperatures of KIV cables, CV cables, etc. are set in advance as caution temperatures and alarm temperatures, and alerts are sent in real time to the PC tablets, smartphones, etc. of the relevant parties using voice, images, numerical values, etc. to automatically shut off breakers, etc. for the distribution boards, distribution boards, control panels, main lines, circuits, etc. of the relevant equipment, or to automatically shut off breakers, etc. for the relevant equipment using computer programs such as AI and IoT, etc., for products, manufacturing, etc., logistics centers, large freezers, refrigerators, etc., lighting, elevators, etc. in commercial facilities where many people gather, terminal buildings, etc., data centers for important data, research and test results, etc., infrastructure substations, etc., various relevant equipment, electrical equipment, etc. in transportation such as trains and ships, etc., relevant terminal equipment, program control, etc. for the relevant electrical equipment, etc. When shutting down according to a predetermined program, the system, which is composed of remote devices for each system such as a distribution board, a distribution panel, a control panel, a main line, a circuit, a breaker, etc., and a cloud server, a LAN, etc., can have an embodiment in which the remote device for the corresponding distribution board, distribution panel, control panel, etc. sends a signal to a protection stop device via an emergency response protection program via the remote devices for each system, the cloud server, the LAN, etc., and all or selected terminal devices, etc., such as control devices, are shut down according to a predetermined program. The system can also have a function to shut down normally and safely and a function to confirm the stop signal.

[0387] The equations are the maximum allowable temperature Joule heat program for each type of electric wire that can be set in advance, the maximum allowable temperature, the Joule heat program combined with time, the caution temperature, the alarm temperature, and the automatic shutoff.

[0388] The rated current program in the DESCON emergency system uses an ammeter CT to detect current A in the relevant circuits, connectors, terminals, etc. of electrical equipment, and converts the current at 83 μsec, which is a common multiple of the power frequency, for example, 50 Hz and 60 Hz, divided by 12,000 times per second, into voltage, and outputs the real analog voltage as an ADC signal. This is used to calculate the type, process, quantity, load, and construction method of products or goods manufactured or researched in the headquarters, factory, development laboratory, store, data center, logistics center, warehouse, large exhibition hall, hotel, terminal building, etc. of the relevant company, etc., in the building facilities such as factories or development laboratories, etc., as well as events, products, goods, banquet halls, etc. handled in stores, data centers, logistics centers, warehouses, large exhibition halls, hotels, terminal buildings, etc. The current values ​​of the distribution boards, main lines, distribution boards, circuits, breakers, junction boxes, branch main control panels, distributors, wiring, terminal equipment, electrical equipment, fixtures, etc. of electrical equipment for a wide variety of businesses, etc., for tenants, etc., depending on the week, month, season, year-end and New Year period, etc., transportation such as trains, cars, ships, airplanes, etc., and renewable energy such as solar, wind, and ocean currents, etc., are detected in real time by ammeters installed on each of the panels, and the current values ​​flowing through the wiring, connectors, etc. are detected based on, for example, the building use, etc., the production or operation of products, etc., and the operating status of load equipment, electrical equipment, etc., relative to the allowable current value based on the wiring size, etc., and the safety protection operation time of the breaker for each current value determined for each size of the main line, wiring, circuit, terminal, etc., for example, a rated current value of 30A is 1.25 times the rated current value, so the protective shutdown operation time of the corresponding breaker for 37.5A can be set to 60 minutes or less.

[0389] In the DESCON emergency system, if the detected current value of a 30A breaker is, for example, 31A, the operation time of the breaker will be within 73 minutes. If the preset operation time is set to, for example, an alert coefficient of 0.7, the alert operation time = (73 minutes x preset alert coefficient 0.7) = 51.10 minutes, and the automatic shutdown operation time for a current of 31A = (73 minutes x 0.9) = 65.7 minutes. For example, the upper limit allowable current for a rated current of 30A is 2.0 times the rated current, and 30A x 2.0 is the same as for a 60A. The breaker operation time is 2.0 minutes, and if the DESCON emergency system detects an overcurrent of, for example, 60A, an alert is sent to the relevant person's PC, smartphone, tablet, etc. with, for example, the customer name, building name, facility name, location, light, type of power, voice, sound, numbers, images, etc., after an alert time of 1.4 minutes has elapsed, with an arbitrarily set alert coefficient of 0.7 = 2 minutes x 0.7 = an arbitrarily set automatic shutoff coefficient of, for example, 2 minutes x 0.9 = 1.8 minutes, and an embodiment can be made in which an alert arbitrary shutoff time of 1.8 minutes is determined.

[0390] The DESCON emergency system also sends alerts to the PCs, smartphones, tablets, etc. of relevant parties to notify them that breakers, etc., on distribution boards, panel boards, control panels, main lines, circuits, etc., and load equipment have been automatically shut off, and continues to send alerts until the relevant parties confirm the alert transmission and reset it.

[0391] The DESCON emergency system automatically shuts off system facilities and electrical equipment that will not be affected by automatic shutdown. For example, automatic shutdown does not apply to products and manufacturing that use computer programs such as AI and IoT, logistics centers, large freezers, refrigerators, lighting and elevators in commercial facilities where many people gather, terminal buildings, hotels, etc., data centers that store important data and research test results, infrastructure substations, and various important facilities and electrical equipment in transportation trains, ships, etc. By shutting down using a predetermined program, an automatic shutdown function is realized that will safely prevent any damage to the relevant facilities, and the relevant terminal facilities and electrical equipment are shut down. The system is configured with remote devices for each system, such as distribution boards, distribution boards, control panels, main lines, circuits, breakers, etc., and a cloud server, LAN, etc., through program control, etc., and the remote devices for each system, such as the relevant distribution boards, distribution boards, control panels, etc., send signals to the protection stop device using an emergency response protection program via the cloud server, LAN, etc., and the system has the function of shutting down the stop function control means and all or selected terminal devices, etc. normally and safely using a predetermined program, and can be an embodiment having the function of normally and safely controlling the stop function and confirming the stop signal.

[0392] The DESCON Emergency System, for the safety protection of electrical equipment, stores a database of the relationship between rated current, current value, and operating time, detects whether the conduction current value of a breaker installed on the panel is equal to or exceeds the rated allowable current value, and, if it exceeds the rated allowable current value, determines the number of minutes within which to shut off the breaker for the corresponding circuit based on the excess current value (A). If it exceeds the rated allowable current value, a message with information such as the customer name, building name, facility name, location, light, power type, voice, or alert is sent to the relevant person's PC, tablet, smartphone, etc., and the relevant equipment's distribution board, distribution panel, control panel, trunk circuit, etc. is connected to a remote device for each system via a cloud server, LAN, etc., and the remote device for the relevant distribution board, distribution panel, control panel, etc. sends a stop signal to the protection shutdown device to safely and reliably shut down the equipment. An embodiment with a function to confirm the stop signal can also be used.

[0393] In the DESCON emergency system, the allowable current for overcurrent is 1.25 times the rated current for each electric wire, and the breaker operation time for an allowable current of 1.25 times the overcurrent is 60 minutes or less.The system calculates an alert transmission coefficient that is set in advance based on the current at which the overcurrent is detected, for an arbitrary time, and sends, for example, the customer name, building name, facility name, location, light, type of power, voice, and an alert to the PC, smartphone, tablet, etc. of the relevant person, and can be embodied in such a way that the relevant electric wire is automatically shut off using an automatic shut-off coefficient that is set in advance.

[0394] The relationship between the operating time and the rated current value, for example, 30 A, is as follows:

[0395] In the DESCON emergency system, for overcurrents relative to the rated current of each electric wire, the allowable current is 1.25 times the rated current, and the operating time of the protective breaker is, for example, 60 minutes for currents of 30 A or less, and 6 minutes or less for breakers with an allowable current of 2.0 times the overcurrent.The system calculates the operating time and an alert transmission coefficient, which is predetermined based on the detection current at which the overcurrent is detected, and sends an alert to the relevant person's PC, smartphone, tablet, etc. using, for example, the customer name, building name, facility name, location, light, type of power source, voice, etc., and can be embodied in such a way that the relevant electric wire is automatically shut off at the detection current of the predetermined automatic shutoff coefficient.

[0396] Electrical equipment, such as distribution boards, main lines, distribution board connectors, circuits, terminals, etc., and branch lines, junction boxes, branch lines, control panels, wiring, terminal load equipment, electrical equipment, wiring, terminal fixtures, etc., are used in the headquarters of companies, factories, development laboratories, stores, data centers, logistics centers, warehouses, large exhibition halls, hotels, terminal buildings, etc. to manufacture and research products or goods, and the types, processes, quantity loads and construction methods of products or goods, etc., and also the operations of the relevant equipment during busy periods such as the week, month, season, year-end and New Year holidays, etc., for events, goods, items, banquet halls, tenants, etc., handled in stores, data centers, logistics centers, warehouses, large exhibition halls, hotels, terminal buildings, etc. Due to high operation, distribution boards, main and branch trunks, distribution boards, control panels, terminal load equipment, electrical equipment, terminal tools, etc., for example, have a rated current of 30A to 2000A for electrical wires, and the current per load equipment exceeds the rated current capacity of the relevant terminal load equipment, electrical equipment equipment, terminal load equipment, etc., and each electrical wire, for example, construction distribution board branch trunks at construction sites, power drums of each wiring, and terminal machinery equipment, electrical equipment equipment, power tools, etc., but if the load electrical capacity or quantity per terminal load machinery equipment, electrical equipment equipment, power tools, etc. is less than the rated current of the relevant panel's connecting fittings, terminals, wiring circuits, trunks, wiring, etc., no overcurrent will occur. On the other hand, for example, if the electrical capacity or number of terminal load machinery, electrical equipment, power tools, etc. connected to the relevant panel, power drum, etc. exceeds the limit due to usage conditions, or if the operating rate of the system equipment exceeds the limit, the current consumed by the electrical equipment may become an overcurrent greater than the rated current in the panel, main line, circuit, etc. of the relevant system.

[0397] For example, thermally activated breakers installed on panels, etc. will shut off the corresponding circuit after a specified time has elapsed, but if the current in the corresponding circuit exceeds the rated current and an overcurrent occurs, for example, as in the case of electrical burns and fires due to overcurrent in temporary and permanent power supplies at construction sites, and electrical burns and fires due to overcurrent in logistics centers and warehouses, etc., when multiple breakers, main lines, circuits, electric wires, connecting fittings, etc. are used simultaneously and the amount of power used exceeds the rated current capacity, if the current capacity exceeds the diameter and conduction area of ​​the specified electric wires, etc., the thermal resistance of the electricity increases, causing the temperature of the corresponding electric wires, main lines, cables, connecting fittings, etc. to rise, generating Joule heat, for example, causing the insulating coating to melt and the connecting fittings to heat up, and there are cases where electrical burns and fires due to overcurrent caused by terminal load equipment, an increase in the number of electrical equipment, an increase in electrical consumption capacity, or multiple use beyond the specified level can occur.

[0398] With the DESCON Emergency System, if a 30A breaker detects a current value of, for example, 31A, the breaker's operation time will be within 73 minutes. If the predetermined operation time is set to, for example, an alert coefficient of 0.7, an alert operation time of (73 minutes x predetermined alert coefficient 0.7) = 51.10 minutes can be set, and an alert will be sent to the relevant parties' PCs, smartphones, tablets, etc. as a warning overcurrent. Another embodiment is also possible in which the automatic shutdown operation time for a 31A current is (73 minutes x predetermined alert coefficient 0.9) = 65.7 minutes. Furthermore, for example, the upper limit allowable current for a rated current of 30 A is 2.0 times the rated current, and 30 A x 2.0 is 60 A, so the breaker operation time is 2.0 minutes; if an overcurrent of 60 A is detected in the manner described above, an alert is sent to the PCs, smartphones, tablets, etc. of the relevant parties as an arbitrarily determined caution overcurrent with an alert coefficient of 0.7, with an alert time of 2 minutes x 0.7 = 1.4 minutes after detection; or an embodiment can be made in which an arbitrarily determined alert cutoff coefficient is used in advance, for example, with a cutoff coefficient of 0.9, with an alert cutoff time of 2 minutes x 0.9 = 1.8 minutes, and the breaker automatically cuts off after an alert cutoff time of 1.8 minutes.

[0399] The DESCON emergency system can be embodied in such a way that it sends an alert to the PC, smartphone, tablet, etc. of the relevant person, and sends information such as the customer name, building name, facility name, location, light, type of power source, voice, and a voice alert to inform the relevant person that breakers, etc., on distribution boards, distribution boards, control panels, main lines, circuits, etc., and load equipment have been automatically shut off, and the alert continues to be sent until the relevant person confirms and resets the alert.

[0400] The DESCON emergency system automatically shuts off system facilities and electrical equipment that would not cause any problems if they were automatically shut off. For example, products, manufacturing, etc. that are controlled by computer programs such as AI and IoT, logistics centers, large freezers, refrigerators, etc., commercial facilities where many people gather, terminal buildings, hotels, etc., lighting, elevators, etc., data centers for important data, research and test results, etc., infrastructure substations, various facilities and electrical equipment in transportation trains, ships, etc., terminal equipment for program control of electrical equipment, etc., etc., will be shut down by a predetermined program, such as distribution boards, distribution The system is composed of remote devices for each system, such as power boards, control panels, main lines, circuits, breakers, etc., and a cloud server, LAN, etc. In one embodiment, the system has the function of sending a signal from the remote devices for each system, such as the relevant distribution boards, distribution boards, control panels, etc. to a protection stop device via an emergency response protection program via the cloud server, LAN, etc., to stop the devices normally and safely, and in another embodiment, the system has the function of shutting down all or selected terminal devices, etc., using a predetermined program, and has the function of stopping the devices normally and safely, as well as the function of confirming the stop signal.

[0401] The DESCON Emergency System can be embodied as a database of the relationship between current value and operating time for the safety protection of electrical equipment, and can detect and input whether the conduction current value of a breaker installed on a panel is below or exceeds the rated allowable current value specified by JIS or other standards, and determine the number of minutes within which the breaker of the corresponding circuit will be shut off based on whether the value is below the rated allowable current value or, if it exceeds the rated allowable current value, the number of A of the exceeded current. Furthermore, when shutting off, alerts are sent to the relevant parties' PCs, tablets, smartphones, etc., including, for example, the customer name, building name, facility name, location, light, type of power source, voice, and other information, and real-time alerts are sent using voice, images, numerical values, etc., and automatic shutoff is performed via an emergency response protection program connected to a remote device for each system via a cloud server, LAN, etc., and the remote device, such as the relevant distribution board, distribution board, control panel, etc., sends a stop signal to the protection stop device, safely and reliably shutting down the circuit and also has the function of confirming the stop signal.

[0402] In the DESCON emergency system, when an overcurrent exceeds the rated current value of each breaker due to an overcurrent, the conductive area of ​​each wire is set, and when a current that exceeds the specified rated current flows, the overcurrent becomes 100% or more of the conductive area, increasing the thermal resistance of the electricity and generating Joule heat. For example, if the temperature of each cable or wire exceeds the IV / KIV allowable temperature of 60°C, VVF allowable temperature of 60°C, VCT allowable temperature of 60°C, HIV allowable temperature of 75°C, CV allowable temperature of 90°C, MLFC allowable temperature of 90°C, etc., and the current value passing through is below the current value at which the breaker thermally operates, or does not reach the current value at which an electronic breaker operates, the breaker does not operate and Joule heat is generated, the allowable temperature of the wire is exceeded, the insulating coating of the wire melts, and the wire is burned. In the event of a fire, for example, the maximum allowable temperature of a CV cable inside the terminal block of a distribution board is 90 degrees, and the detected temperatures when the power is turned on, for example, R phase 33.2 degrees, S phase 33.3 degrees, and T phase 32.9 degrees, are detected and stored in a database, and the maximum allowable temperature of 90 degrees is set as a warning temperature, and the alarm temperature is set arbitrarily in advance, for example, as 95 degrees, which is the maximum allowable temperature + 5 degrees, or if a temperature of 95 degrees continues for one minute or more and rises above 95 degrees, it is set as an alarm temperature, the relevant circuit is automatically shut off, and an alert is sent to the PC, tablet, or smartphone of the relevant person with, for example, the customer name, building name, facility name, location, light, type of power source, voice, voice, etc., numbers, images, etc., and the alert ringtone continues until the relevant person checks and resets it, preventing the relevant person from missing out on checking.

[0403] The DESCON Emergency System can be embodied in such a way that an alarm temperature is triggered when, for example, a distribution board, distribution panel, junction box, connection device, terminal fixture, connection equipment, terminal, electrical device / tool, cable, or electric wire exceeds an allowable temperature, for example, an arbitrary temperature determined in advance based on allowable temperatures for cables, electric wires, etc., for each temperature, such as an IV / KIV allowable temperature of 60°C, a VVF allowable temperature of 60°C, a VCT allowable temperature of 60°C, an HIV allowable temperature of 75°C, a CV allowable temperature of 90°C, or an MLFC allowable temperature of 90°C, if the temperature exceeds an allowable temperature of, for example, +10 to +15°C for any period of five minutes, or if the allowable temperature exceeds +15°C. In this case, the system can be embodied in such a way that an alarm temperature is triggered when the temperature of the relevant cable, circuit, connection device, terminal, etc. exceeds an allowable temperature. In addition, an embodiment can be implemented in which the relevant parties' PCs, tablets, and smartphones are alerted with, for example, the customer name, building name, facility name, location, light, type of power source, voice, voice, etc., as well as voice, numbers, and images of the alarm temperature and automatic shutdown, and the alert ringtone continues to be sent by email until the relevant parties confirm and reset, preventing the relevant parties from missing out on checking.

[0404] The DESCON emergency system can be embodied in such a way that, for example, Joule heat is generated and exceeds the allowable temperature of connecting fittings, terminals, electric wires, circuits, etc., causing the coating material to burn or melt, etc., causing the relevant electric wires, circuits, etc. to short out, causing a spark tracking phenomenon to occur.When the temperature of the relevant electric wires, etc. rises due to Joule heat and exceeds the allowable temperature of each electric wire to an arbitrarily determined temperature before the insulating coating material melts, the DESCON emergency system sends an alert to the PCs, smartphones, tablets, etc. of the relevant parties, sending audio, numerical values, images, etc., such as the customer name, building name, facility name, location, light, type of power source, voice, etc., and further, if the temperature rises to an arbitrarily determined temperature, the system will automatically shut off, and the system can detect and determine the occurrence of a spark tracking phenomenon caused by Joule heat, for example, melting or burning the coating material of the electrical resistance of the relevant cables, electric wires, circuits, etc.

[0405] When the temperature of the relevant connecting fittings, terminals, circuits, wires, etc. rises above the allowable temperature set for each type of wire, the insulating coating material that prevents short circuits and sparks in the wires melts due to the rise in Joule heat, causing spark tracking at the melted point, resulting in electrical burnout and potentially causing an electrical fire.

[0406] Conventional thermal conduction breakers operate by blocking the temperature of the relevant circuit, screws, bolts, terminals, etc. of the connecting fittings when an overcurrent value A is reached and over time has elapsed, and the overcurrent prevention function protects the relevant circuit, connecting fittings, etc. from electrical burnout, etc.

[0407] An electronic breaker will conduct current to the relevant circuit etc. based on the allowable current standards for the relevant circuit, screws, bolts, terminals and other connecting hardware. For example, a safe allowable current value A is set in advance, and when the set current value A is reached, the protective function of the breaker will be activated and cut off, protecting the relevant circuit, connecting hardware etc. from electrical burnout etc. by preventing overcurrent. The thermal conduction breaker's protective function is activated when the temperature rises, and the electronic breaker's protective function is activated when the allowable current value A is reached.

[0408] The DESCON emergency system is a system that detects currents in the circuits, fittings, terminals, etc. of electrical equipment due to overcurrents, etc., and converts currents into voltages at various power frequencies, such as 50Hz, 60Hz, etc., for example, 12,000 times per second for 83μsec, and converts the real analog voltages into analog-to-digital converters (ADCs). This is then used by a microcomputer, etc. to detect thermal activation of the relevant panel circuits, fittings such as screws, bolts, terminals, cables, wires, terminal load equipment, etc., and electronic breakers, etc., not operating, and also detects short circuits, tracking, etc., due to deterioration or melting of wire coating materials caused by Joule heat due to electric thermal resistance heat caused by currents below the allowable current, for example, 8 In 3 μsec, the system detects, for example, currents 15 to 80 times the normal current, or the allowable temperature of the relevant circuit wire, and sends an alert to the relevant person's PC, smartphone, tablet, etc., including, for example, the customer name, building name, facility name, location, light, power type, voice, voice, numerical value, image, etc., and automatically shuts off the relevant circuit, connector cable, electric wire, control IoTB, terminal load equipment, etc., when the current reaches, for example, 20 times or more the predetermined normal current. This system prevents serious electrical burns and electrical fires due to, for example, Joule heat melting the insulating coating of the electric wire, short sparks, and tracking phenomena, which has a significant effect on preventing personal injury accidents both socially, economically, and domestically. Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and can be modified in various ways within the technical scope understood from the claims.
