DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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 cut-off feasibility determination means, a first power supply cut-off device, a second power supply cut-off 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, which are 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 equipment includes, for example, various substation equipment, switchboards, distribution boards, electric lighting boards, power boards, control boards, remote control device boards, and junction boxes for branch wiring connections of extension cords or wiring between distribution boards and distribution boards and devices / appliances.

[0018] The first electrical device is disposed within the housing that constitutes the above-mentioned power device, and provides electrical connection between the power source side circuit from the power source side and the load side circuit toward the load, and examples of this include a main breaker and a ground fault circuit interrupter.

[0019] The second electric devices are circuit breakers of a different type from the above-mentioned main breaker, earth leakage breaker, etc. For example, a magnet switch, a power relay, a solid state relay, etc. may be used.

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

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

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

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

[0024] The unit of time for instantaneous detection is, for example, 1 / 12000th of a second = 83 microseconds, and can be set arbitrarily between 1 / 50,000th of a second (= 20μsec) and 1 / 100,000th of a second (= 10μsec). Also, within this range, it can be set to a microsecond that is proportional to the performance of the computer (PC) that constitutes the DESCON emergency system.

[0025] Setting the instantaneous time unit for instantaneous time detection to microseconds between 1 / 50,000th of a second (=20μsec) and 1 / 100,000th of a second (=10μsec) is advantageous in preventing and controlling the occurrence of overcurrents that can cause electrical burnout or fires, and in taking necessary measures such as cutting off the power before electrical burnout or fires 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 in which the instantaneous current value was detected, corresponding to the cable size of the load side electric circuit in which the instantaneous current value was detected.

[0027] For example, the current value that is pre-allowed for the load side electric circuit for which the instantaneous current value was detected in accordance with the cable size of the load side electric 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 electric circuit of that cable size, which is the allowable current value range that is pre-allowed.

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

[0029] The power supply automatic interruption possibility determination means performs processing to determine whether the load to which current is supplied via the load side electric circuit determined to be passing an instantaneous current exceeding the allowable current value range is a load to which power supply can be automatically interrupted, when the instantaneous current value determination device determines that the instantaneous current value range is exceeded, by referring to the allowable protective operation time allowed for the current breaker that cuts off the current to the load side electric circuit determined to be passing 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 passing reaches the allowable protective operation time.

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

[0031] The first power supply cut-off device performs a process of cutting off current to the load-side electric circuit determined to be carrying an instantaneous current exceeding the allowable current value range by the current breaker, in order to cut off the power supply to the load determined by the power supply automatic cut-off feasibility determination means to be capable of automatically cutting off the power supply.

[0032] The second power supply cut-off device, when the power supply automatic cut-off feasibility determination means determines that the power supply cannot be automatically cut off, cuts off the power supply to the load device control device controlling the load for which it has been determined that the power supply cannot be automatically cut off, and then causes the circuit breaker to cut off the current to the load side electric circuit in which it has been determined that an instantaneous current exceeding the allowable current value range is flowing.

[0033] The first power supply cut-off device and the second power supply cut-off device in the server computer device perform the above-mentioned processing under a specified computer program, and send cut-off instruction information to the above-mentioned power supply cut-off device and load device control device via a wired or wireless network installed between the above-mentioned power supply cut-off device and load device control device (e.g., a computer) and the server computer device, thereby 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 allowable current value range is exceeded.

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

[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 processing is performed in which 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 set to any microsecond time between 1 / 50,000th of a second (=20 μsec) and 1 / 100,000th of a second (=10 μsec).

[0038] For example, detection at an extremely short time can be instantaneous detection at 1 / 12000th of a second = 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 lead to 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 manager terminal can be configured with a personal computer or the like equipped with an image information display means such as a monitor. The person in charge terminal can be configured with a mobile terminal such as a smartphone to which an application for operating the system 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 exchange information with each other.

[0042] The computer system, which is composed of a server computer and the like that constitutes the digital emergency electric safety control system of the present invention, is composed of a computer having a configuration in which, although not shown, a CPU that performs control so that the various functions of the system of this embodiment are realized in accordance with an operating system or a specific computer program that has 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 a hard disk that store data necessary for the CPU to execute processing 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.

[0043] The processing operations performed by the above-mentioned instantaneous current value determination device, instantaneous current value determination device, power supply automatic cut-off feasibility 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 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. do not necessarily need to be configured to be all arranged in a single device or equipment.

[0045] For example, a device or equipment having some of these configurations may be installed in an electric power device, and this device or equipment may be installed away from the electric power device and connected to other devices or equipment consisting of a computer having other configurations so that they can communicate with each other via a wired or wireless network.

[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 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 they can communicate with each other via a wired or wireless network.

[0047] In the above, the configuration may include a server computer installed on the cloud among one or more other devices or equipment that are deployed away from the power device, connected via a wired or wireless network, and have some or the remaining configurations of the other configurations described above. <Various embodiments of the DESCON emergency system of the present invention and various functions performed> In the DESCON emergency system, the rated current program for overcurrent is a current meter CT that detects current A in the relevant circuits, connecting fittings, terminals, etc. of the electrical equipment, and converts the current of 83μsec, which is a common multiple of the power frequency, for example, 50Hz and 60Hz, divided by 12,000 times per second, into a voltage, and outputs a real analog voltage as an ADC trunk line and electric lights, power equipment distribution boards, junction boxes, branch trunk lines, control panels, distributors, wiring, each terminal equipment, electrical equipment, instruments, etc., and the type, process, quantity, load and construction method, etc. of products or goods manufactured and researched in factories or development laboratories, etc. of the relevant company's headquarters, factories, development laboratories, stores, data centers, logistics centers, warehouses, large exhibition halls, hotels, terminal buildings, etc., and 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 boards, distributors, wiring, each terminal equipment, electrical equipment, instruments, etc. of the electrical equipment, such as the weekly, monthly, seasonal, year-end and New Year periods of the factories, tenants, etc., and the electrical equipment, such as the means of transportation such as trains, cars, ships, airplanes, etc., and the electrical equipment, such as the distribution boards, circuits, breakers, junction boxes, branch trunk control boards, distributors, wiring, each terminal equipment, electrical equipment, instruments, etc. are detected in real time by the ammeter CT installed in each of the above panels, and the current is calculated according to the wiring size, etc. For example, the current value passing through the wiring, connecting fittings, etc. is detected based on the building use, etc., the production or operation of products, etc., and the operating status of load equipment, electrical equipment, etc., and the safety protection operation time of the breaker is determined based on the current value determined by the size of the main line, wiring, circuit, terminal, etc., for example, for a rated current value of 30A, the protective cut-off operation time of the corresponding breaker is 1.25 times the rated current value, and for a rated current value of 37.5A, the protective cut-off operation time 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) Circuit breaker → (6) Safety protection operation time → (7) Rated current value 30A → (8) Rated current value → (9) 1.25 times → (10) 37.5A → (11) Protection cutoff 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, then the alert operation time = (73 minutes x preset alert coefficient 0.8) = 58.4 minutes, and the automatic shutoff operation time for the current of 31A will be (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 times, or 60A, is 2.0 minutes. 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, voice, number, image, etc., with an arbitrarily determined alert coefficient of 0.7 = 2 minutes x 0.7 and an alert time of 1.4 minutes, and the predetermined 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, and to send alerts that breakers, etc., on distribution boards, switchboards, 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) Activation time → (4) Within 73 minutes → (5) Alert coefficient 0.8 → (6) Alert activation time = (73 minutes x predefined alert coefficient 0.8) = 58.4 minutes → (7) Automatic shutdown activation time for 31A current = (73 minutes x 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) 30A x 2.0 times = 60A → (13) Operating time 2.0 minutes → (14) Overcurrent 60A → (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., system equipment, electrical equipment, etc. that will not be affected if they are automatically shut off, or, for example, products, production, etc., using 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 for important data, research and test results, etc., infrastructure substations, solar power plants, wind power plants, geothermal power plants, tidal power plants, etc., transportation trains, ships, etc., and various other important facilities, electrical equipment, etc. that are not subject to automatic shutoff or are shut down by a predetermined program, and do not cause any disruption to the safety of the relevant facilities, etc. The system is configured with program control of the relevant terminal equipment, electrical devices, etc., and the control terminal equipment, etc. 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 has a function of shutting down all or selected terminal equipment, etc. normally and safely according to a predetermined program by sending a signal from the remote devices for each system, such as the relevant distribution boards, distribution boards, control panels, etc. to the protection stop device via an emergency response protection program via a cloud server, LAN, etc., and can be configured with a control means for normally and safely stopping the terminal equipment, etc., all at once or selected, according to a predetermined program, and a control means for a function of confirming the stop signal.

[0053] This flow can be displayed, for example, as follows: (1) Automatic shutoff → (2) No problem → (3) Automatic shutoff → (4) Shutdown by program → (5) Automatic shutoff function that does not interfere with 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 shutdown 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 determine whether it is appropriate to be below the rated allowable current value, and if it exceeds the rated allowable current value, to determine within how many minutes the relevant circuit will be shut off depending on the current value A that exceeds it.If it exceeds the rated allowable current value, for example, the customer name, building name, facility name, location, light, type of power, voice, voice, alert, etc. are sent to the relevant person's PC, tablet, smartphone, etc., and the distribution board, distribution board, control board, main line, circuit, etc. of the relevant equipment are connected to remote devices by system, etc., via a cloud server, LAN, etc., and the remote devices of the relevant distribution board, distribution board, control board, etc. send a stop signal to the protection stop device by the emergency response protection program, so that the remote devices can safely and reliably stop the circuit and also have the function of confirming the stop signal.

[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 the rated allowable current value → (6) Exceeded → (7) Appropriateness below the rated allowable current value → (8) Exceeds the rated allowable current value → (9) Exceeding current value (A) → (10) Within how many minutes → (11) Shuts off the relevant circuit → (12) If it exceeds → (13) Sends an alert

[0056] The DESCON emergency system has an overcurrent tolerance of 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 the predetermined time period, and sends information such as customer name, building name, facility name, location, light, type of power, voice, and an alert to the PCs, smartphones, tablets, etc. of the relevant persons, and automatically shuts off the relevant electric wire at the automatic shutoff current value, with the automatic shutoff coefficient set arbitrarily in advance.

[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 of 60 minutes or less → (5) Alert transmission coefficient → (6) Custom time → (7) Automatic shutoff current value → (8) Automatic shutoff

[0058] For the safety protection of electrical equipment, the DESCON emergency system, for example, if a rated current of 30A is 1.25 times the rated current, which is an allowable current of 37.5A, and the operation time is 60 minutes, then the operation time for a detection current value of 33A is 68.2 minutes, and with an alert coefficient of 0.9 and an alert time of 61.36 minutes, then an alert is sent to the relevant person's PC, smartphone, tablet, etc. to inform them that the detection current of 33A has exceeded the rated current of 30A, and information such as the customer name, building name, facility name, location, light, type of power, voice, voice, the relevant distribution board, control board, circuit name, etc. is sent. Also, if the detection current of 33A continues beyond the alert time, it will automatically The shutoff coefficient is 0.95 and the automatic shutoff time is 64.8 minutes, and the relevant distribution boards, control panels, circuits, etc., terminal load equipment, electrical devices, etc. 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 the remote devices for the relevant distribution boards, distribution boards, control panels, etc. send a stop signal to the protection stop device via an emergency response protection program, allowing the system to be configured to protect and confirm safety.

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

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

[0061] According to the above, the DESCON emergency system, for example, if the capacity of the lighting distribution board No. 1 is 25.0 kW and the current is 119 A, and the rated current is 125 A, then "the allowable current is 1.25 times the rated current = (current 125 A x 1.25) = 156.3 A, and 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, and with a rated current alert coefficient of 1.01 determined in advance, the rated alert current = (rated current 125 A x 1.01) = 126.25 A, the system transmits to the PC, smartphone, tablet, etc. of the person concerned predetermined information such as the customer name, building name, facility name, location, light, type of power, voice, the relevant distribution board, control board, circuit name, etc. to the tablet, smartphone, etc. An alert is sent by voice or the like, and an automatic shutoff occurs when a predetermined, arbitrarily determined current (rated current 125A x automatic shutoff coefficient 1.05 times = 131.25A) continues for 10 minutes, or when (rated current 125A x automatic shutoff coefficient 1.1 times = 135.0A) is automatically shut off. An alert is sent to the PC, smartphone, tablet, etc. of the relevant person, which is predetermined in advance, for example, customer name, building name, facility name, location, light, type of power, voice, and the relevant distribution board, control board, circuit name, 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 board, trunk line, circuit, etc., is connected to a cloud server LAN, etc. by a professional program, so that the remote device can transmit a stop signal to the protection stop device and confirm safety protection.

[0062] Regardless of the above, the DESCON emergency system can be configured to send an allowable alert as described above with an allowable current of 156.3A, which is 1.25 times the rated current, with an arbitrarily determined 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, electric machines, etc. with 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) Capacity of lighting distribution board No. 1: 25.0 kW → (2) Current: 119 A → (3) Rated current: 125 A → (4) Rated current multiplied by 1.25 = (current 125 A x 1.25) = 156.3 A is the allowable current → (5) The detected current is 135 A, which is smaller than the allowable current → (6) Breaker operation time = 120 minutes x (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 x 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 × Magnification 1.05) = 164.1A

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

[0065] According to the above, the DESCON emergency system, for example, the capacity of the lighting distribution board No. 1 is 25.0 kW, the current is 119 A, and the rated current of 125 A is 1.25 times the rated current = (current 125 A x 1.25) = 156.3 A, which is the allowable current. If the detected current is 175 A, which exceeds the allowable current, the breaker operation time = 120 minutes x (allowable current 156.3 A / detected current 175 A) = 107.2 minutes, and the rated current alert coefficient is set to 1.01, which is a preset arbitrary rated current alert coefficient. The alert current is set to (rated current 125A x 1.01) = 126.25A, and the relevant PC, smartphone, tablet, etc. is sent an alert with, for example, the customer name, building name, facility name, location, light, type of power, voice, the relevant distribution board, control board, circuit name, etc., to the tablet, smartphone, etc., and the previously determined (rated alert current 125A x automatic shutoff coefficient 1.03 times = 161A) is set to 1. An alert can be sent to the PC, smartphone, tablet, etc. of the relevant person that the current has been automatically shut off for 10 minutes or (rated alert current 125A x automatic shutoff coefficient 1.4 times = 175A) and a pre-defined alert, for example, customer name, building name, facility name, location, light, type of power, voice, voice, the relevant distribution board, control board, circuit name, etc., can be sent to the tablet, smartphone, etc., and an alert can be sent to the PC, tablet, smartphone, etc. of the relevant person that the current has been automatically shut off for 10 minutes or (rated alert current 125A x automatic shutoff coefficient 1.4 times = 175A) and a pre-defined alert, for example, customer name, building name, facility name, location, light, type of power, voice ...

[0066] Notwithstanding the above, it is also possible to configure an allowable current type with an allowable current of 156.3A, which is 1.25 times the rated current, and with an arbitrarily determined alert coefficient of 0.9, for example, (alert allowable current 156.3A x 0.9) = 140.67A, which sends an allowable alert as described above, and also with an automatic shutoff alarm current = (allowable current 156.3A x multiplication factor 1.05) = 164.1A, which automatically shuts off the relevant panels, circuits, etc., terminal load equipment, electrical machinery, etc., and sends an automatic shutoff alert to relevant parties as described above.

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

[0068] For the safety protection of electrical equipment, the DESCON emergency system, for example, if a rated current of 30A is 2.0 times the rated current, which is an allowable current of 60.0A, and the operation time is 2 minutes, the operation time for a detection current value of 63A is 5.7 minutes, and with an alert coefficient of 0.85 and an alert time of 4.86 minutes, an alert is sent to the relevant person's PC, smartphone, tablet, etc. to inform them that the detection current is 63A, which exceeds the rated current of 30A, and includes, for example, the customer name, building name, facility name, location, light, type of power, voice, voice, the relevant distribution board, control board, circuit name, etc., and if the detection current of 33A continues beyond the alert time, it will automatically The shutoff coefficient is 0.95 and the automatic shutoff time is 5.48 minutes, and the relevant distribution boards, control panels, circuits, etc., terminal load equipment, electrical devices, etc. 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 the remote devices for the relevant distribution boards, distribution boards, control panels, etc. send a stop signal to the protection stop device via an emergency response protection program, allowing safety protection and confirmation.

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

[0070] In the DESCON emergency system, if the detection current is, for example, 30A, then (rated current x 2.0) = allowable current, and the allowable breaker operating time is 6 minutes. If it is "less than the allowable current", the following can be done. According to the above, for example, the capacity of the power distribution board No. 1 is 58.1 kW and the current is 200 A. The rated current of 225 A is 2.0 times the rated current, so that (current 225 A x 2.0) = 450 A is the allowable current. If the detected current is 420 A, which is smaller than the allowable current, the breaker operation time is (12 minutes x (detected current 420 A / allowable current 450 A) = 12.85 minutes. With a rated current alert coefficient of 1.01 determined in advance, the rated alert current = (rated current 225 A x 1.01) = 227.2 A. The DESCON emergency system transmits information, such as the customer name, building name, facility name, location, light, type of power, voice, the relevant distribution board, control board, circuit name, etc., determined in advance to the PC, smartphone, tablet, etc. of the person concerned, in the form of, for example, the customer name, building name, facility name, location, light, type of power, voice, etc. An alert is sent to the PCs, smartphones, tablets, etc. of the relevant persons to inform them that the previously determined "rated current 225A x automatic shutoff coefficient 1.05 times = 236.3A" has continued for 10 minutes, or that the "rated current 225A x automatic shutoff coefficient 1.1 times = 247.5A" has been automatically shut off. The alert information, for example, the customer name, building name, facility name, location, light, type of power, voice, and the relevant distribution board, control board, circuit name, etc. can be sent to the tablet, smartphone, etc., and the remote devices, etc. for the emergency response protection system, such as the relevant distribution board, distribution board, control board, main line, circuit, etc., can be connected by a professional program to a cloud server LAN, etc., so that the remote devices, such as the relevant distribution board, distribution board, control board, etc., 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, which sends an allowable alert as described above with an allowable current of 450A, which is 1.25 times the rated current, with an arbitrarily determined alert coefficient of 0.9, for example (alert allowable current 450A x 0.9) = 405A, and automatically shuts off the relevant panels, circuits, etc., terminal load equipment, electrical machinery, etc. with an automatic shut-off alarm current = (allowable current 450A x multiplication factor 0.93) = 418.5A, and sends an alert to relevant parties that an automatic shut-off has occurred as described above.

[0072] 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) Rated current: 225 A → (4) Rated current multiplied by 2.0 = (current 225 A x 2.0) = 450 A is the allowable current → (5) The 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 transmission → (10) (Rated current 225 A x automatic breaker Cut-off coefficient 1.05 times = 236.3A → (11) 10 minutes → (12) (Rated current 225A × automatic cut-off coefficient 1.1 times = 247.5A → (13) Automatic cut-off → (14) Alert sent → (15) Allowable current 450A, calculated by multiplying the rated current by 1.25 → (16) Alert coefficient 0.9 → (17) Alert allowable current 450A × 0.9) = 405A → (18) Allowable alert sent → (19) Automatic cut-off alarm current = (Allowable current 450A × Magnification 0.93) = 418.5A → (20) Automatic cut-off → (21) Alert sent for automatic cut-off

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

[0074] According to the above, the DESCON emergency system assumes that, for example, the capacity of the power distribution panel No. 1 is 58.1 kW and the current is 200 A. The rated current of 225 A is 2.0 times the rated current, so that (current 225 A x 2.0) = 450 A is the allowable current. If the detected current is 510 A, which is greater than the allowable current, then the breaker operation time is 12 minutes x (allowable current 450 A / detected current 510 A) = 10.58 minutes. With a rated current alert coefficient of 1.1 that is arbitrarily determined in advance, the rated alert current = (rated current 2 25A x 1.1) = 247.5A, and send an alert to the relevant person's PC, smartphone, tablet, etc. with information such as customer name, building name, facility name, location, light, type of power, voice, and the relevant distribution board, control board, circuit name, etc., which have been arbitrarily determined in advance, to the tablet, smartphone, etc., and send the alert with information such as customer name, building name, facility name, location, light, type of power, voice, and the relevant distribution board, control board, circuit name, etc., and send the alert with information such as customer name, building name, facility name, location, light, type of power, voice, and the relevant distribution board, control board, circuit name, etc., to the tablet, smartphone, etc., and send the alert with information such as customer name, building name, facility name, location, light, type of power, voice, and the relevant distribution board, control board, circuit name, etc., which have been arbitrarily determined in advance, to the tablet, smartphone, etc., and send the alert with information such as customer name, building name, facility name, location, light, type of power, voice, and the relevant distribution board, control board, circuit name ... An alert is sent to the PC, smartphone, tablet, etc. of the person concerned to inform them that the automatic shutdown occurred at a current of 225A x 1.5 times the automatic shutdown coefficient = 337.5A, and information such as the customer name, building name, facility name, location, light, type of power, voice, the relevant distribution board, control board, circuit name, etc., which can be determined arbitrarily in advance, is sent to the tablet, smartphone, etc. Also, since the automatic shutdown occurred at a current of 337.5A, which can be determined arbitrarily in advance, is sent to the tablet, smartphone, etc., and The 510A can also send an alert to the relevant person's PC, tablet, smartphone, etc., notifying them of the automatic shutdown, for example with the customer name, building name, facility name, location, light, type of power, voice, etc., and through 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 board, main line, circuit, etc. of the relevant equipment, so that the remote devices such as the relevant distribution board, distribution board, control board, etc. can send a stop signal to the protection stop device to provide safety protection and confirmation.

[0075] Notwithstanding the above, it is also possible to configure an allowable current type where the rated current is multiplied by 1.25 to be 510A, with an arbitrarily determined alert coefficient of 0.9, for example, and the alert allowable current is 510A x 0.9 = 459A, and an allowable alert is sent as described above, and where the automatic shutoff alarm current = (allowable current 510A x multiplication factor 1.05) = 535.5A, the relevant panels, circuits, etc., terminal load equipment, electrical machinery, etc. are automatically shut off, and an automatic shutoff alert is sent to relevant parties as described above.

[0076] 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) Rated current: 225 A → (4) Rated current multiplied by 2.0 = (current: 225 A x 2.0) = 450 A 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 shutdown coefficient: 1.3 times = 292.5 A) → (11) 10 minutes → (12) Rated alert 225A rated current × 1.5x automatic shutoff coefficient = 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) Rated current multiplied by 1.25, 510A allowable current → (20) Alert coefficient 0.9 → (21) Alert allowable current 510A × 0.9 = 459A → (22) Allowable alert sent → (23) Automatic shutoff warning current = (allowable current 510A × 1.05x coefficient) = 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 power distribution board No. 1 with a capacity of 58.1 kW and a current of 200 A, for example, a CT that measures current in low-voltage distribution boards, distribution boards, control boards, circuits, etc., and in each control board and circuit of the terminal load equipment and electrical equipment of the system, is used to measure the current of the applicable "breaker rated current of 225 A" for the power distribution board No. 1 with a capacity of 58.1 kW and a current of 200 A, which may cause electrical burnout, electrical fire, etc. In order to prevent and control the occurrence of overcurrent, for example, if an excess current of 226A, which exceeds the rated current of the distribution board of 225A, is detected as a warning overcurrent, an alert will be sent to the PC, smartphone, tablet, etc. of the relevant person, including, for example, the customer name, building name, facility name, location, light, type of power, voice, voice, the relevant distribution board, control board, circuit name, etc. For example, if the current passing through the relevant distribution board is the detection current of 305A, a message such as "Detection current 305A - breaker For an alarm overcurrent of 80A for "rated current 225A = 80A," if the automatic shutdown current standard is arbitrarily set to 225A in advance, the automatic shutdown current = (detection current 305A - breaker rated current 225A) = 80A), and among the circuits No. 1 to No. 12 in the system of the electric lighting distribution board No. 1, the circuits that can be automatically shut off and the circuits that cannot be automatically shut off are sorted in advance, and the priority of the circuits that can be automatically shut off is set, and the overcurrent of 80A is 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, electric light, type of power, voice, voice, etc., and automatically via the distribution board, distribution board, control board, main line, circuit, etc. of the relevant equipment, a remote device for each emergency response protection system, etc., and a cloud server, LAN, etc. can be programmed to configure a system in which the remote device of the relevant distribution board, distribution board, control board, etc. sends a stop to the protection stop device to confirm safety protection.

[0078] In addition, the system can be set up to alert the relevant parties of the automatic shutdown by sending audio, numerical values, images, etc. of the relevant information, such as the customer name, building name, facility name, location of the light, type of power, capacity, electrical equipment at the system terminal, and name of the load equipment, and continue to send such information until the relevant parties check and reset it, preventing them from missing any checks.

[0079] This flow can be displayed, for example, as follows: (1) Capacity of power distribution board No. 1 is 58.1KW → (2) Current is 200A → (3) Capacity of power lighting distribution board No. 1 is 58.1KW, current is 200A → (4) Rated current is 225A → (5) Overcurrent occurs → (6) Rated current 225A → (7) Excess current 226A → (8) Caution overcurrent → (9) Send alert → (10) Detected current 135A → (11) Detected current 135A - breaker rated current 125A = 10A → (12) Warning overcurrent 80A → (13) Set automatic cutoff current standard to 225A → (14) Automatic cutoff current = (Detected current 305A - breaker rated current 225A) = 80A) → (15) Circuits NO1 to NO12 → (16) Circuits that can be automatically cut off and circuits that cannot be automatically cut off → (17) Priority of circuits that can be automatically cut off → (18) Overcurrent 80A → (19) Automatic cutoff → (20) Send alert → (21) Check and reset → (22) Continuous transmission

[0080] <Various other embodiments of the DESCON emergency system of the present invention and various functions performed> The DESCON emergency system detects current, voltage, temperature, images, etc. of substation equipment, distribution boards, control panels, main lines, circuits, breakers, remote devices, etc., as well as load terminal equipment, electrical equipment equipment, etc., and determines whether the value is normal or abnormal by referring to various pre-entered databases. For example, when an abnormal value occurs, it sends an alert to relevant parties with information such as the customer name, building name, facility name, location, relevant panel, circuit light, power type, capacity, electrical equipment at the system terminal, load equipment name, etc. in the form of voice, numbers, images, etc. in real time via PC, tablet or smartphone.

[0081] According to the DESCON emergency system, if the abnormal value becomes high, "an alert is sent using audio, visual and numerical warning signals," "the panel, main line, circuit, breaker, etc. of the relevant equipment is automatically shut off," "an alert is sent to relevant parties using audio, visual and numerical signals that the automatic shutoff has occurred," "the alert continues to be sent until the relevant parties confirm and reset," and "safely respond to recovery in real time after the automatic shutoff."

[0082] The above-mentioned automatic shutoff is, for example, when products, production, etc., are automatically shut off by computer programs such as AI and IoT, 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., various facilities, electrical equipment, etc., such as trains and ships for transportation, and terminal equipment, electrical equipment, etc., as described above, and when these are controlled by a computer based on a computer program, the terminal equipment, etc. for control, etc. are shut off by a predetermined program. In the case of shutting down, 2) the DESCON emergency system, which is composed of remote devices for each system such as distribution boards, distribution boards, control panels, main lines, circuits, breakers, etc., a cloud server, LAN, etc., has an emergency response protection program that uses remote devices for each system, a cloud server, LAN, etc. to send a signal to the protection stop device from the remote devices such as the relevant distribution boards, distribution boards, control panels, etc., and the control equipment, etc., as a whole or selected terminal equipment, etc., has the function of shutting down according to a predetermined program, and is characterized by a control means for normally and safely stopping the function and a control means for 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 the information to the relevant person's PC, tablet, smartphone, etc. using a predetermined program, such as the customer name, building name, facility name, location, each panel circuit, etc., for the lights and power, and compares the numerical values, etc. of the year, season, month, week, day, hour, minute, etc. with the year, season, month, week, day, hour, minute, etc., and records the numerical values, etc. of the current, voltage, insulation, temperature, etc., and whether they are normal or abnormal in a database, and the above content can be displayed periodically on the relevant person's PC, tablet, smartphone, etc. and display by the program, or automatically printed out.

[0084] The DESCON emergency system is connected to a fire alarm on a disaster prevention panel of a building facility, for example, a fire alarm, receives abnormal signals from the smoke detector and heat detector of the fire alarm, identifies the floor and area where the signal was received, and automatically shuts off electricity and other equipment necessary for evacuation, safety, etc., such as evacuation, fire alarms, broadcasting equipment emergency guide lights, lighting, mechanical smoke exhaust, air supply, etc., as well as predetermined lights and power equipment, and sends audio, image and numerical alerts to relevant parties in real time via PC, tablet or smartphone, such as 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 them, allowing for an embodiment that allows for safety response in real time to restore operation after automatic shutdown.

[0085] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made within the technical scope understood from the description of the claims.
