[0028] FIG. 14 is a diagram illustrating another example of a control flow for detecting and controlling an overcurrent by a digital emergency electric safety control system.

[0015] The digital emergency electric safety control system of the present invention comprises a power device, an AC instantaneous current value detection device, an instantaneous current value determination device, a first alarm notification information output means, a power supply automatic cutoff possibility determination means, a first power supply cutoff device, a second power supply cutoff device, an internal housing temperature information acquisition means, an electric circuit temperature information acquisition means, an internal housing temperature monitoring means, a load side electric circuit temperature information monitoring means, a second alarm notification information output means, and a third alarm notification information output means.

[0016] The power device has a power supply-side electric circuit from a power source side and a plurality of load-side electric circuits branching from the power supply-side electric circuit and heading toward a plurality of loads, and is electrically connected within a housing, and a first electric device is interposed in the power supply-side electric circuit within the housing, and a second electric device is interposed in each of the plurality of load-side electric circuits within the housing. The first electric device interposed in the power supply-side electric circuit and the plurality of second electric devices interposed in each of the plurality of load-side electric circuits are both disposed within the housing.

[0017] Such power devices include, for example, various substation equipment, distribution boards, panelboards, 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 and panelboards and equipment and appliances.

[0018] The first electrical device is arranged within the housing that constitutes the above-mentioned power device, and establishes an electrical connection between the power supply side circuit from the power source side and the load side circuit toward the load, and examples thereof include a main breaker and a ground fault circuit breaker.

[0019] The plurality of second electrical devices are circuit switches of a type different from the above-mentioned main breaker, earth leakage breaker, etc. Examples thereof include a magnetic switch, a power relay, and a solid-state relay.

[0020] Examples of loads that the load side circuit is directed to include power / electrical devices and equipment that operate by receiving power supply, such as prime movers, elevators, air conditioning equipment, ventilation equipment, lighting equipment, refrigerated / freezer cases, refrigerators / freezers, measuring instruments, computer equipment, surveillance cameras, medical equipment, and communication equipment, and include power / electrical devices and equipment that are deployed and used both inside and outside of buildings, power / electrical devices and communication devices and equipment that are deployed and used in vehicles and means of transportation such as trains, cars, airplanes, and ships, as well as outlets to which these are connected.

[0021] These loads are connected to the tip ends of the respective load-side electric circuits.

[0022] The AC instantaneous current value detection device is connected to the load side electric circuit and detects the instantaneous current value, which is the value of the current flowing through the load side electric circuit at an instant in time.

[0023] As the AC instantaneous current detector, a current sensor using an instrument current transformer called a CT (Current Transformer) can be used.

[0024] 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.

[0025] 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 preventing and controlling the occurrence of overcurrent, which can cause electrical burnout, electrical fires, etc., and in taking necessary measures, such as cutting off the power supply, before electrical burnout, electrical fires, etc. occur.

[0026] The instantaneous current value determination device performs a process of comparing the detected instantaneous current value with an allowable current value range, which is a current value range that is pre-allowed for the load side electric circuit for which the instantaneous current value was detected, corresponding to the cable size of the load side electric circuit for which the instantaneous current value was detected.

[0027] For example, the current value that is pre-allowed for the load side circuit for which the instantaneous current value was detected in accordance with the cable size of the load side circuit for which the instantaneous current value was detected can be, for example, less than 1.25 times the rated current set for the load side circuit of that cable size, which is the pre-allowed current value range.

[0028] The instantaneous current value determination device in the server computer device acquires the information detected by the above-mentioned AC instantaneous current value detector via a wired or wireless network between the server computer device and the AC instantaneous current value detector, and performs the above-mentioned processing under a specified computer program.

[0029] When the instantaneous current value determination device determines that the instantaneous current value range is exceeded, the power supply automatic interruption possibility determination means performs processing to refer to the allowable protective operation time allowed for the circuit breaker that cuts off the current to the load side electric circuit in which it is determined that an instantaneous current exceeding the allowable current value range is flowing, and when the time during which the instantaneous current exceeding the allowable current value range is flowing reaches the allowable protective operation time, determine whether the load to which current is supplied via the load side electric circuit in which it is determined that an instantaneous current exceeding the allowable current value range is flowing is a load in which power supply automatic interruption is possible.

[0030] The automatic power supply cutoff possibility determining means in the server computer device performs the above-mentioned processing under a predetermined computer program.

[0031] The first power supply cutoff device performs a process to cut off power supply to the load that is determined by the power supply automatic cutoff feasibility determination means to be capable of automatic power cutoff, by using the current breaker to cut off current to the load side electrical circuit that is determined to be carrying an instantaneous current exceeding the allowable current value range.

[0032] 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 for which it has been determined that the automatic power supply cutoff is not possible, and then causes the circuit breaker to cut off the current to the load-side electrical circuit for which it has been determined that an instantaneous current exceeding the allowable current value range is flowing.

[0033] The first power supply cutoff device and the second power supply cutoff device in the server computer device perform the above-mentioned processing under a predetermined computer program, and send cutoff instruction information to the above-mentioned power supply cutoff device and load device control device via a wired or wireless network installed between the above-mentioned power supply cutoff device and load device control device (e.g., a computer) and the server computer device, causing the above-mentioned processing operation to be performed.

[0034] The above-mentioned digital emergency electric safety control system further includes a first alarm notification information output means for outputting first alarm notification information together with information identifying the power device associated with the housing to an administrator terminal used by an administrator managing the power device and to a staff terminal owned by a staff member in charge of managing the power device when the instantaneous current value determination device determines that the instantaneous current value exceeds the allowable current value range.

[0035] The above-mentioned digital emergency electric safety control system further includes a second alarm notification information output means which, when the instantaneous current value determination device determines that the allowable current value range is exceeded, refers to the allowable protective operation time allowed for the circuit breaker that cuts off the power supply to the load side circuit determined to be carrying an instantaneous current exceeding the allowable current value range, and when the time during which the instantaneous current exceeding the allowable current value range is flowing reaches the allowable protective operation time, outputs second 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.

[0036] The above-mentioned first alarm notification information output means and second alarm notification information output means in the server computer device perform the above-mentioned processing under a specified computer program, and the above-mentioned first alarm notification information and second alarm notification information are output to the above-mentioned administrator terminal and person in charge terminal connected to the server computer device via a wired or wireless network.

[0037] In the above-mentioned digital emergency electric safety control system, the instantaneous time can be any microsecond time between 1 / 50,000 seconds (=20 μsec) and 1 / 100,000 seconds (=10 μsec).

[0038] For example, detection in an extremely short time can be instantaneous detection in 1 / 12000 seconds = 83 microseconds, where 12000 is a common multiple of, for example, 50 Hz and 60 Hz.

[0039] Doing so is advantageous in preventing and controlling the occurrence of overcurrent, which can be a cause of electrical burnout, electrical fires, etc., and in taking necessary measures, such as cutting off the power supply, before electrical burnout, electrical fires, etc. occur.

[0040] The administrator terminal can be configured as a personal computer equipped with a monitor or other image information display means, and the staff terminal can be configured as a mobile terminal such as a smartphone on which the system operation application of the present invention has been downloaded.

[0041] The administrator terminal and the person in charge terminal are connected to a computer system consisting of a server computer and the like that constitutes the digital emergency electric safety control system of the present invention via a communication network such as the Internet or a dedicated line so that they can communicate information with each other.

[0042] The computer system, which is made up of a server computer and the like that constitutes the digital emergency electric safety control system of the present invention, is not shown, but is made up of a computer that is equipped with a CPU that performs control so that the various functions of the system of this embodiment are realized in accordance with an operating system and predetermined computer programs that have been installed or downloaded, 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 processing for each control, a RAM and hard disk that store data necessary for the CPU to execute processing and are also used as a work area where information can be rewritten by the CPU as appropriate, information input / output units such as a communication interface, and the like, all of which are connected by the necessary bus lines.

[0043] The processing operations performed by the above-mentioned instantaneous current value determination device, instantaneous current value determination device, power supply automatic cut-off possibility determination means, first power supply cut-off device, second power supply cut-off device, first alarm notification information output means, second alarm notification information output means, etc. are executed by such a computer system.

[0044] The above-mentioned instantaneous current value determination device, instantaneous current value determination device, power supply automatic cutoff possibility determination means, first power supply cutoff device, second power supply cutoff device, first alarm notification information output means, second alarm notification information output means, etc. do not all need to be configured to be installed in a single device or equipment.

[0045] For example, a device or equipment having some of the above configurations may be installed in a power device, and this may be installed away from the power device and connected to another device or equipment consisting of a computer having other configurations via a wired or wireless network so that information can be exchanged.

[0046] Alternatively, a device or equipment having some of the above-mentioned configurations may be installed in the power device, and this may be installed away from the power device and connected via a wired or wireless network to other devices or equipment consisting of a computer having some of the other configurations, and other devices or equipment consisting of a computer having the remaining parts of the other configurations, so that information can be exchanged.

[0047] In the above, the configuration may also be such that a server computer installed on a cloud is included in one or more other devices or equipment that are deployed in a location away from the power device, connected via a wired or wireless network, and that have some or the rest of the other configurations described above. <Various embodiments of the DESCON emergency system of the present invention and various functions to be performed> In the DESCON emergency system, the rated current program for overcurrent is performed by using an ammeter CT to detect current A in the relevant circuits, connectors, terminals, etc. of the electrical equipment, and converting the current of 83 μsec, which is a common multiple of the power frequency, for example, 50 Hz and 60 Hz, by dividing 1 second by 12,000 times, into voltage, and outputting the real analog voltage as an ADC signal. This is used to measure 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 distribution board, junction box, branch main line, control panel, distributor, wiring, each terminal equipment, electrical equipment, fixtures, etc. of the relevant company, etc., in the building facilities such as factories or development laboratories, etc., as well as events, goods, items, banquets, etc. handled in stores, data centers, logistics centers, warehouses, large exhibition halls, hotels, terminal buildings, etc. The current values ​​of the electrical equipment such as distribution boards, trunk lines, lighting, power equipment distribution boards, circuits, breakers, junction boxes, branch trunk control panels, distributors, wiring, each terminal equipment, electrical equipment, appliances, etc., for a wide variety of businesses, etc. depending on the week, month, season, year-end and New Year period of the premises, tenants, etc., as well as means of transportation such as trains, cars, ships, and airplanes, and renewable energy such as solar, wind, and ocean currents, are detected in real time by the current meters CT installed on each panel, and the current is calculated according to the wiring size, etc. The current value passing through the wiring, connecting fittings, etc. is detected based on, for example, the building use, etc., the production or operation of products, etc., and the operating conditions of load facilities, electrical equipment, etc., relative to the allowable current value of the value, and the safety protection operating time of the breaker is determined based on the 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, and the protective shut-off operating time of the corresponding breaker for 37.5A is, for example, 60 minutes or less.

[0048] This flow can be displayed, for example, as follows: (1) Rated current program → (2) Current meter CT → (3) By size → (4) By current value → (5) Breaker → (6) Safety protection operation time → (7) Rated current value 30 A → (8) Rated current value → (9) 1.25 times → (10) 37.5 A → (11) Protection breaker operation time → (12) 60 minutes or less

[0049] For example, if the DESCON emergency system detects that 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 0.8, the alert operation time = (73 minutes x preset alert coefficient 0.8) = 58.4 minutes, and the automatic shutdown operation time for the 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 the breaker operation time for 30A x 2.0 = 60A is 2.0 minutes. In the same way, 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, numerical value, image, etc., using an arbitrarily determined alert coefficient of 0.7 = 2 minutes x 0.7 and an alert time of 1.4 minutes, and the predetermined arbitrary automatic cut-off coefficient is, for example, 2 minutes x 0.9 = 1.8 minutes, and a means for determining the arbitrary alert cut-off time of 1.8 minutes can be provided.

[0050] In addition, the DESCON emergency system can be configured to send alerts to the PCs, smartphones, tablets, etc. of relevant parties, alerting them that breakers, etc., on distribution boards, panel boards, control panels, main lines, circuits, etc., and load equipment have been automatically shut off, and the system will continue to send alerts until the relevant parties confirm the alert transmission and reset it.

[0051] This flow can be displayed, for example, as follows: (1) 30A breaker → (2) 31A → (3) Operation time → (4) Within 73 minutes → (5) Alert coefficient 0.8 → (6) Alert operation time = (73 minutes × predetermined alert coefficient 0.8) = 58.4 minutes → (7) Automatic shutdown operation time for 31A current = (73 minutes × 0.9) = 65.7 minutes → (8) Automatic shutdown → (9) Rated current 30A → (10) Upper limit allowable current → (11) 2.0 times the rated current → (12) 30 A x 2.0 = 60 A → (13) Operating time 2.0 minutes → (14) Overcurrent 60 A → (15) Alert arbitrary coefficient 0.7 = 2 minutes x 0.7 → (16) Alert time 1.4 minutes → (17) Alert sent → (18) Automatic shutoff coefficient → (19) 2 minutes x 0.9 = 1.8 minutes → (20) Shutting down time 1.8 minutes → (21) Alert sent

[0052] The DESCON emergency system automatically shuts off terminal load equipment, electrical equipment, etc. that will not cause any problems if they are automatically shut off. For example, products, manufacturing, etc. that use computer programs such as AI and IoT, logistics centers, large freezers, refrigerators, etc., lighting, elevators, etc. in commercial facilities where many people gather, terminal buildings, hotels, etc., data centers that store important data, research and test results, etc., infrastructure substations, solar power plants, wind power plants, geothermal power plants, tidal power plants, etc., and various other important facilities, electrical equipment, etc. that are used for transportation such as trains and ships, are not subject to automatic shut-off, or the automatic shut-off function shuts down according to a predetermined program, so that the relevant facilities are not affected safely. The system is configured by program control of the relevant terminal equipment, electrical equipment, etc., and the control terminal equipment, etc. is made up 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 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., to shut down all or selected terminal equipment, etc. normally and safely using a predetermined program, and can be configured to have a control means for controlling the stop function normally and safely, and a control means for confirming the stop signal.

[0053] This flow can be displayed as follows, for example: (1) Automatic shutdown → (2) No problem → (3) Automatic shutdown → (4) Shutdown by program → (5) Automatic shutdown function that does not cause a problem to safety → (6) Program control → (7) Emergency response protection program → (8) Send signal to protection stop device → (9) All at once → (10) Selection → (11) Shutdown by program → (12) Normal and safe stop function control means → (13) Stop signal confirmation function

[0054] The DESCON emergency system is configured to have a database of the relationship between rated current, detected current value, and operating time for the safety protection of electrical equipment, and to detect and input whether the detected current of the breaker installed on the panel is within or exceeds the rated allowable current value, and to have a means for determining whether it is appropriate to be below the rated allowable current value, and if it exceeds the rated allowable current value, to determine how many minutes it will take to shut off the relevant circuit depending on the current value (A) that has exceeded it, and if it has exceeded it, to send, for example, the customer name, building name, facility name, location, light, type of power, voice, audio, or alert to the relevant person's PC, tablet, smartphone, etc., and the distribution board, distribution board, control panel, main line, circuit, etc. of the relevant equipment to remote devices by system, via a cloud server, LAN, etc., an emergency response protection program, and the remote devices of the relevant distribution board, distribution board, control panel, etc. will send a stop signal to the protection stop device, safely and reliably stopping the function, and the stop signal can be confirmed.

[0055] This flow can be displayed, for example, as follows: (1) Rated current → (2) Detected current value → (3) Operating time → (4) Detected current → (5) Below rated allowable current value → (6) Exceeding → (7) Proper value below the rated allowable current value → (8) Exceeding the rated allowable current value → (9) Exceeding current value (A) → (10) Within how many minutes → (11) Shut off the circuit → (12) If it exceeds → (13) Send alert

[0056] The DESCON emergency system detects overcurrents with a current allowable to be 1.25 times the rated current for each electric wire, and the breaker operation time is 60 minutes or less.The system calculates a predetermined alert transmission coefficient based on the current at which the overcurrent is detected, and for that predetermined time, sends an alert to the PC, smartphone, tablet, etc. of the relevant person, with information such as the customer name, building name, facility name, location, light, type of power source, and voice.The system can then automatically shut off the relevant electric wire at the predetermined automatic shutoff current value using an automatic shutoff coefficient.

[0057] This flow can be displayed, for example, as follows: (1) Rated current → (2) Overcurrent → (3) 1.25 times the rated current → (4) Breaker operation time is 60 minutes or less → (5) Alert transmission coefficient → (6) Arbitrary time → (7) Automatic shutdown current value → (8) Automatic shutdown

[0058] For the safety protection of electrical equipment, the DESCON Emergency System sends an alert to the relevant parties' PCs, smartphones, tablets, etc., informing them that, for example, a rated current of 30A is 1.25 times the rated current, which is 37.5A, and the operating time is 60 minutes, and the operating time for a detected current value of 33A is 68.2 minutes, and the alert coefficient is 0.9 and the alert time is 61.36 minutes, indicating that the detected current of 33A exceeds the rated current of 30A. The alert includes, for example, the customer name, building name, facility name, location, light, type of power, voice, voice, the name of the relevant distribution board, control board, circuit, etc. If the detected current of 33A continues beyond the alert time, the system will automatically The shutoff coefficient is set to 0.95, and the automatic shutoff time is 64.8 minutes. The relevant distribution boards, control panels, circuits, etc., as well as terminal load equipment and electrical devices, are automatically shut off, and an alert is sent to the PCs, tablets, smartphones, etc. of the relevant persons, for example, with the customer name, building name, facility name, location, light, type of power, voice, etc., and the distribution boards, distribution boards, control panels, main lines, circuits, etc. of the relevant equipment are connected to remote devices by system, etc., via a cloud server, LAN, etc., and an emergency response protection program allows the remote devices of the relevant distribution boards, distribution boards, control panels, etc. to send a shutdown signal to the protection stop device, thereby enabling safety protection and confirmation to be configured.

[0059] This flow can be displayed, for example, as follows: (1) Rated current 30 A → (2) Rated current x 1.25 → (3) Allowable current 37.5 A → (4) Operating time 60 minutes → (5) Detected current value 33 A → (6) Operating time 68.2 minutes → (7) Alert coefficient 0.9 → (8) Alert time 61.36 minutes → (9) Detected current 33 A → (10) Automatic shutdown coefficient is 0.95 → (11) Automatic shutdown time 64.8 minutes → (12) Automatic shutdown → (13) Alert sent

[0060] In the DESCON emergency system, if the detection current is, for example, 30 A (rated current x 1.25 = allowable current), the allowable breaker operating time is 60 minutes. If the current is less than the allowable current, the following can be done.

[0061] As described above, the DESCON emergency system assumes that, for example, the capacity of the lighting distribution panel No. 1 is 25.0 kW and the current is 119 A, and the rated current is 125 A, the allowable current is 1.25 times the rated current = (current 125 A x 1.25) = 156.3 A. If the detected current is 135 A, which is smaller than the allowable current, then the breaker operation time = 120 minutes x (allowable current 156.3 A / detected current 135 A) = 138.9 minutes. Assuming that the arbitrarily determined rated current alert coefficient is 1.01, and the rated alert current = (rated current 125 A x 1.01) = 126.25 A, the relevant person's PC, smartphone, tablet, etc. is sent information arbitrarily determined in advance, such as the customer name, building name, facility name, location, light, type of power, voice, voice, relevant distribution board, control panel, circuit name, etc. to the tablet, smartphone, etc. An alert is sent by voice or the like, and an automatic shutdown has occurred when a predetermined, arbitrarily determined current (rated current 125A x automatic shutdown coefficient 1.05 times = 131.25A) has continued for 10 minutes, or when a predetermined, arbitrarily determined current (rated current 125A x automatic shutdown coefficient 1.1 times = 135.0A) has been reached. An alert is sent to the PC, smartphone, tablet, etc. of the relevant person, including predetermined, arbitrarily determined information such as the customer name, building name, facility name, location, light, type of power, voice, and the name of the relevant distribution board, control panel, circuit, etc., to a tablet, smartphone, etc., and a remote device for each emergency response protection system, such as the relevant distribution board, distribution board, control panel, main line, circuit, etc., is connected to a cloud server LAN or the like by a program, so that the remote device can send a shutdown signal to the protection shutdown device to confirm safety protection.

[0062] Regardless of the above, the DESCON emergency system can also be configured to send an allowable alert as described above when the allowable current is 156.3A, which is 1.25 times the rated current, with an arbitrarily set alert coefficient of 0.9, for example, (alert allowable current 156.3A x 0.9 = 140.67A), and to automatically shut off the relevant panels, circuits, etc., terminal load equipment, electrical machines, etc. when the current = (allowable current 156.3A x multiplication factor 1.05 = 164.1A, and to send an alert to the relevant parties that an automatic shutdown has occurred as described above.

[0063] This flow can be displayed, for example, as follows: (1) Lighting distribution panel No. 1 capacity 25.0 kW → (2) Current 119 A → (3) Rated current 125 A → (4) Rated current multiplied by 1.25 = (current 125 A × 1.25) = 156.3 A is the allowable current → (5) Detected current is 135 A, which is smaller than the allowable current → (6) Breaker operation time = 120 minutes × (allowable current 156.3 A / detected current 135 A) = 138.9 minutes → (7) Rated current alert coefficient 1.01 → (8) Rated alert current = (rated current 125 A × 1.01) = 126.25 A → (9) Alert sent → (10) Rated current 125A × automatic shutoff coefficient 1.05 times = 131.25A → (11) 10 minutes → (12) (Rated current 125A × automatic shutoff coefficient 1.1 times = 135.0A) → (13) Automatic shutoff → (14) Alert sent → (15) Allowable current 156.3A, calculated by multiplying the rated current by 1.25 → (16) Alert coefficient 0.9 → (17) (Alert allowable current 156.3A × 0.9) = 140.67A → (18) Allowable alert sent → (19) Automatic shutoff alarm current = (Allowable current 156.3A × multiplication factor 1.05) = 164.1A

[0064] In the DESCON emergency system, if the detection current is, for example, 30 A, then (rated current x 1.25) = allowable current, and the allowable breaker operating time is 60 minutes. If the allowable current is greater than this, the following can be done.

[0065] As described above, the DESCON emergency system detects that, for example, the capacity of the lighting distribution panel No. 1 is 25.0 kW and the current is 119 A, and the rated current is 125 A, the rated current is multiplied by 1.25 = (current 125 A x 1.25) = 156.3 A, which is the allowable current. If the detected current exceeds the allowable current and reaches 175 A, the breaker operation time is 120 minutes x (allowable current 156.3 A / detected current 175 A) = 107.2 minutes, and the rated alert coefficient is set to 1.01, which is a predetermined arbitrary rated current alert coefficient. The alert current is set to (rated current 125A x 1.01) = 126.25A, and an alert is sent to the PC, smartphone, tablet, etc. of the person in charge, with information such as the customer name, building name, facility name, location, light, type of power, voice, and the name of the relevant distribution board, control panel, circuit, etc., which are arbitrarily determined in advance, such as (rated alert current 125A x automatic shutoff coefficient 1.03 times = 161A) to 1. If the alarm continues for 0 minutes, or if the alarm is automatically shut off at (rated alert current 125A x automatic shutoff coefficient 1.4 times = 175A), an alert is sent to the PC, smartphone, tablet, etc. of the person in charge, including the customer name, building name, facility name, location, light, type of power, voice, and the name of the relevant distribution board, control panel, circuit, etc., and also includes ... An alert is sent to the PC, tablet, smartphone, etc. of the relevant person to inform them that the equipment has been automatically shut off, for example, with the customer name, building name, facility name, location, light, type of power, voice, etc., and a remote device for each emergency response protection system and a cloud server LAN, etc. can be connected by a professional program via the distribution board, distribution board, control panel, main line, circuit, etc. of the relevant equipment, and the remote device for the relevant distribution board, distribution board, control panel, etc. can send a stop signal to the protection stop device, thereby creating a system that can protect and confirm safety.

[0066] Furthermore, regardless of the above, it is also possible to configure an allowable current type where the rated current is multiplied by 1.25 to be 156.3 A, and for example, an arbitrarily set alert coefficient is 0.9, so that (alert allowable current 156.3 A x 0.9) = 140.67 A, and an allowable alert is sent as described above, and the automatic shutoff alarm current = (allowable current 156.3 A x multiplication factor 1.05) = 164.1 A, which automatically shuts off the relevant panels, circuits, etc., terminal load equipment, electrical machines, etc., and sends an automatic shutoff alert to the relevant parties as described above.

[0067] This flow can be displayed as follows, for example: (1) Lighting distribution panel No. 1 capacity 25.0 kW → (2) Current 119 A → (3) Rated current 125 A → (4) Rated current multiplied by 1.25 = (current 125 A × 1.25) = 156.3 A, which is the allowable current → (5) Detected current exceeds the rated current, 175 A → (6) Breaker operation time = 120 minutes × (156.3 A / 175 A) = 107.2 minutes → (7) Rated current alert coefficient 1.01 → (8) Rated alert current = (rated current 125 A × 1.01) = 126.25 A → (9) Alert sent → (10) (Rated alert current 125 A × automatic shutdown coefficient 1.03 = 161 A) → (11) 1 0 minutes → (12) Rated alert current 125 A × automatic shutoff coefficient 1.4 times = 175 A → (13) Automatic shutoff has occurred (14) Alert sent → (15) Detected current 175 A → (16) Automatic shutoff has occurred → (17) Alert sent → (18) Allowable current 156.3 A, calculated by multiplying the rated current by 1.25 → (19) Alert coefficient 0.9 → (20) Allowable alert current 156.3 A × 0.9 = 140.67 A → (21) Allowable alert sent → (22) Automatic shutoff warning current = (allowable current 156.3 A × multiplication factor 1.05) = 164.1 A → (23) Automatic shutoff → (24) Automatic shutoff alert sent

[0068] For the safety protection of electrical equipment, the DESCON emergency system sends an alert to the relevant person's PC, smartphone, tablet, etc., informing them that, for example, a rated current of 30A is 2.0 times the rated current, which is an allowable current of 60.0A, and with an operating time of 2 minutes, a detected current value of 63A will have an operating time of 5.7 minutes, an alert coefficient of 0.85, and an alert time of 4.86 minutes, indicating that the detected current of 63A exceeds the rated current of 30A. The alert will include, for example, the customer name, building name, facility name, location, light, type of power source, voice, voice, the relevant distribution board, control panel, circuit name, etc. If the detected current of 33A continues beyond the alert time, an automatic The shutoff coefficient is set to 0.95, and the automatic shutoff time is 5.48 minutes. The relevant distribution boards, control panels, circuits, etc., as well as terminal load equipment and electrical devices, are automatically shut off, and an alert is sent to the PCs, tablets, smartphones, etc. of the relevant persons, for example, with the customer name, building name, facility name, location, light, type of power, voice, etc., and the distribution boards, distribution boards, control panels, main lines, circuits, etc. of the relevant equipment are connected to remote devices by system, etc., via a cloud server, LAN, etc., and an emergency response protection program allows the remote devices of the relevant distribution boards, distribution boards, control panels, etc. to send a shutdown signal to the protection stop device, thereby enabling safety protection and confirmation.

[0069] This flow can be displayed, for example, as follows: (1) Rated current 30 A → (2) Rated current x 2.0 → (3) Allowable current 60.0 A → (4) Operating time 2 minutes → (5) Detected current value 63 A → (6) Operating time 5.7 minutes → (7) Alert coefficient 0.85 → (8) Alert time 4.86 minutes → (9) Automatic shutdown coefficient 0.95 → (10) Automatic shutdown time 5.48 minutes → (11) Automatic shutdown → (12) Alert transmission

[0070] In the DESCON emergency system, if the detected current is, for example, 30A, then (rated current x 2.0) = allowable current, and the allowable breaker operating time is 6 minutes. If the current is "less than the allowable current," then the following can be done. For example, in the DESCON emergency system, if the capacity of power distribution panel No. 1 is 58.1 kW and the current is 200A, and the rated current is 225A, then 2.0 times the rated current = (current 225A x 2.0) = 450A, and if the detected current is 420A, which is less than the allowable current, then the breaker operating time = (12 minutes x (detected current 420A / allowable current 450A) = 12.85 minutes, and the allowable current can be set as desired in advance. Assuming that the rated current alert coefficient is 1.01, and the rated alert current = (rated current 225A x 1.01) = 227.2A, the relevant person's PC, smartphone, tablet, etc. will be notified of the customer name, building name, facility name, location, light, type of power, voice, relevant distribution board, control panel, circuit name, etc., which have been arbitrarily determined in advance. An alert is sent to the PC, smartphone, tablet, etc. of the relevant person to notify that the current has automatically shut off at a predetermined, arbitrarily determined "rated current 225A x automatic shutoff coefficient 1.05 times = 236.3A" that has continued for 10 minutes, or at a "rated current 225A x automatic shutoff coefficient 1.1 times = 247.5A" that has been automatically shut off. The alert includes predetermined, arbitrarily determined information such as the customer name, building name, facility name, location, light, type of power, voice, and the name of the relevant distribution board, control panel, circuit, etc., and is sent to the tablet, smartphone, etc., and a remote device for each emergency response protection system, such as the relevant distribution board, distribution board, control panel, main line, circuit, etc., is connected by a professional program to a cloud server LAN, etc., via the distribution board, distribution board, control panel, main line, circuit, etc. of the relevant equipment, so that the remote device can send a stop signal to the protection stop device to confirm safety protection.

[0071] Regardless of the above, the DESCON emergency system can also be configured as an allowable current type, where an allowable current of 450A is set as 1.25 times the rated current, and an arbitrarily set alert coefficient is set as 0.9, for example, so that (alert allowable current 450A x 0.9) = 405A, and an automatic shutoff alarm current = (allowable current 450A x multiplication factor 0.93) = 418.5A is set, and an alert is sent to relevant parties that an automatic shutoff has occurred as described above.

[0072] This flow can be displayed as follows, for example: (1) Capacity of power distribution panel No. 1: 58.1 kW → (2) Current: 200 A → (3) Rated current: 225 A → (4) Rated current multiplied by 2.0 = (current 225 A x 2.0) = 450 A, which is the allowable current → (5) Detected current is 420 A, which is smaller than the allowable current → (6) Breaker operation time = (12 minutes x (detected current 420 A / allowable current 450 A)) = 12.85 minutes → (7) Rated current alert coefficient: 1.01 → (8) Rated alert current = (rated current 225 A x 1.01) = 227.2 A → (9) Alert sent → (10) (rated current 225 A x automatic breaker) Interruption coefficient 1.05 times = 236.3 A → (11) 10 minutes → (12) (rated current 225 A × automatic shutoff coefficient 1.1 times = 247.5 A → (13) Automatic shutoff confirmed → (14) Alert sent → (15) Allowable current 450 A obtained by multiplying the rated current by 1.25 → (16) Alert coefficient 0.9 → (17) Alert allowable current 450 A × 0.9) = 405 A → (18) Allowable alert sent → (19) Automatic shutoff warning current = (allowable current 450 A × magnification 0.93) = 418.5 A → (20) Automatic shutoff → (21) Alert sent for automatic shutoff

[0073] In the DESCON emergency system, if the detected current is, for example, 30 A, then (rated current x 1.25) = allowable current, and the allowable breaker operating time is 60 minutes. If the current is greater than the allowable current, the following can be done.

[0074] As described above, the DESCON emergency system calculates the allowable current by multiplying the rated current by 2.0, which is (current 225A x 2.0) = 450A. If the detected current is 510A, which is greater than the allowable current, the breaker operation time is 12 minutes x (allowable current 450A / detected current 510A) = 10.58 minutes. The rated current alert coefficient is set to 1.1, and the rated alert current is calculated as (rated current 2.0). 25A x 1.1) = 247.5A, and an alert is sent to the PC, smartphone, tablet, etc. of the person in charge, with predetermined information, such as the customer name, building name, facility name, location, light, type of power, voice, and the name of the relevant distribution board, control panel, circuit, etc., to the tablet, smartphone, etc., and a predetermined rated alert current of 225A x automatic shutoff coefficient 1.3 times = 292.5A continues for 10 minutes, or the rated alert current is An alert is sent to the PC, smartphone, tablet, etc. of the person in charge to inform them that the system has automatically shut down at a current of 225A x 1.5 times the automatic shutoff coefficient = 337.5A, and the information is sent to the tablet, smartphone, etc. with the customer name, building name, facility name, location, light, type of power, voice, and the name of the relevant distribution board, control panel, circuit, etc., which have been arbitrarily determined in advance. Also, since the system has automatically shut down at a predetermined automatic shutoff current of 337.5A, the detected current is The 510A also sends an alert to the relevant person's PC, tablet, smartphone, etc., informing them of the automatic shutdown, for example, with the customer name, building name, facility name, location, light, type of power, voice, or other information, and by using a professional program, remote devices for each emergency response protection system and cloud server LAN, etc., can be connected via the distribution board, distribution board, control panel, main line, circuit, etc. of the relevant equipment, so that the remote devices of the relevant distribution board, distribution board, control panel, etc. can send a shutdown signal to the protection shutdown device, thereby enabling a system to be created in which safety protection and confirmation can be achieved.

[0075] Furthermore, regardless of the above, it is also possible to use an allowable current type where the rated current is multiplied by 1.25 to give an allowable current of 510A, and with an arbitrarily set alert coefficient of 0.9, for example, the alert allowable current is 510A x 0.9 = 459A, and an allowable alert is sent as described above, and the automatic shutoff alarm current = (allowable current 510A x multiplier 1.05) = 535.5A, which automatically shuts off the relevant panels, circuits, etc., terminal load equipment, electrical machinery, etc., and sends an automatic shutoff alert to the relevant parties as described above.

[0076] This flow can be displayed as follows, for example: (1) Capacity of power distribution panel No. 1: 58.1 kW → (2) Current: 200 A → (3) Rated current: 225 A → (4) Rated current multiplied by 2.0 = (current 225 A x 2.0) = 450 A, which is the allowable current → (5) Detected current is 510, which is greater than the allowable current → (6) Breaker operation time = 12 minutes x (allowable current 450 A / detected current 510 A) = 10.58 minutes → (7) Rated current alert coefficient: 1.1 → (8) Rated alert current = (rated current 225 A x 1.1) = 247.5 A → (9) Alert sent → (10) (Rated alert current 225 A x automatic trip coefficient 1.3 = 292.5 A) → (11) 10 minutes → (12) Rated alert Current 225A × automatic shutoff coefficient 1.5 = 337.5A → (13) Automatic shutoff has occurred. (14) Alert sent → (15) Automatic shutoff current 337.5A → (16) Detected current 510A → (17) Automatic shutoff has occurred → (18) Alert sent → (19) Allowable current 510A, calculated by multiplying the rated current by 1.25 → (20) Alert coefficient 0.9 → (21) Allowable alert current 510A × 0.9 = 459A → (22) Allowable alert sent → (23) Automatic shutoff warning current = (Allowable current 510A × Magnification 1.05) = 535.5A → (24) Automatic shutoff → (25) Automatic shutoff alert sent → (25) Automatic shutoff alert sent

[0077] In the DESCON emergency system, in order to prevent an overcurrent of the capacity of 58.1 kW and current of 200 A of the power distribution panel No. 1, for example, a CT that measures current in low-voltage distribution panels, distribution panels, control panels, circuits, etc., and in each control panel and circuit of the system terminal load equipment, electrical equipment, etc., will detect that the applicable "breaker rated current of 225 A" of the capacity of the power distribution panel No. 1, for example, 58.1 kW and current of 200 A, exceeds the applicable "breaker rated current of 225 A", which may cause electrical burnout, electrical fire, etc. In order to prevent and control the occurrence of overcurrent, for example, an excess current of 226A that exceeds the rated current of the distribution board of 225A is treated as a caution overcurrent, and an alert is sent to the PC, smartphone, tablet, etc. of the person concerned, including, for example, the customer name, building name, facility name, location, light, type of power, voice, voice, the name of the relevant distribution board, control panel, circuit, etc. For example, if the current flowing through the relevant distribution board is a detected current of 305A, a message such as "Detected current 305A - breaker For an alarm overcurrent of 80A for a "rated current of 225A = 80A," if the automatic shutdown current standard is set to 225A in advance, the automatic shutdown current = (detection current 305A - breaker rated current 225A) = 80A), and circuits Nos. 1 to 12 in the system of lighting distribution board No. 1 are sorted in advance into those that can be automatically shut off and those that cannot, and a priority is set for the circuits that can be automatically shut off, automatically shutting off the overcurrent of 80A, and an alert is sent to the PC, tablet, smartphone, etc. of the relevant person with, for example, the customer name, building name, facility name, location, light, type of power, voice, etc., and automatically transmitted via the distribution board, distribution board, control board, main line, circuit, etc. of the relevant equipment to remote devices for each emergency response protection system, cloud server, LAN, etc., by programming, so that the remote devices of the relevant distribution board, distribution board, control board, etc. can send a stop signal to the protection stop device to confirm safety protection.

[0078] Furthermore, the system can be set up so that the relevant parties can be notified of the automatic shutdown by sending an alert to their PCs, tablets, smartphones, etc. with audio, numerical values, images, etc., including the customer name, building name, facility name, location light, power type, capacity, electrical equipment at the grid terminal, and load equipment name, and the alerts will continue to be sent until the relevant parties confirm and reset, preventing them from missing any confirmation.

[0079] This flow can be displayed, for example, as follows: (1) Capacity of power distribution panel No. 1: 58.1 kW → (2) Current: 200 A → (3) Capacity of power lighting distribution panel No. 1: 58.1 kW, current: 200 A → (4) Rated current: 225 A → (5) Overcurrent occurs → (6) Rated current 225A → (7) Excess current 226A → (8) Warning overcurrent → (9) Send alert → (10) Detected current 135A → (11) Detected current 135A - breaker rated current 125A = 10A → (12) Warning overcurrent 80A → (13) Set automatic shutdown current standard to 225A → (14) Automatic shutdown current = (detected current 305A - breaker rated current 225A) = 80A) → (15) Circuits No. 1 to No. 12 → (16) Circuits that can be automatically shut off and circuits that cannot be automatically shut off → (17) Priority of circuits that can be automatically shut off → (18) Overcurrent 80A → (19) Automatic shutdown → (20) Send alert → (21) Confirm and reset → (22) Continuous transmission

[0080] <Various other embodiments of the DESCON emergency system of the present invention and various functions to be exerted> The DESCON emergency system is configured to detect the 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, and the alert is sent in the form of audio, numerical values, images, etc., and the following information is sent in real time to a PC, tablet, or smartphone: customer name, building name, facility name, location, light on the relevant panel, circuit, etc., type of power, capacity, electrical equipment at the system terminal, name of load equipment, etc.

[0081] 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."

[0082] 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.

[0083] 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.

[0084] 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.

[0085] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible within the technical scope that can be grasped from the claims.
