Description

[Technical Field]

[0001] This invention relates to a system for monitoring and controlling power receiving and transforming equipment installed on an electric circuit from a power supply side to a plurality of loads, and by monitoring and controlling the step-down distribution transformers, i.e., high-voltage transformers, installed in the power receiving and transforming equipment, and the electrical equipment installed on the electric circuit after the voltage has been stepped down by the high-voltage transformer in the power receiving and transforming equipment, the system prevents the occurrence of electrical accidents that could lead to fires and other such accidents, and prevents the occurrence of accidents that could damage the various electric power, electrical equipment, and devices that make up the plurality of loads, and further relates to a system for preventing the occurrence of electrical accidents and the like due to short circuits, sparks, tracking, etc. in the low-voltage distribution boards, distribution boards, control panels, system trunk lines, wiring, terminal electrical equipment, terminal load equipment, etc. in the power receiving and transforming equipment. [Background technology]

[0002] The applicant of the present application has named a digital electric safety control system (Patent Document 1) "Descon" and has already put into practice a system that prevents electrical accidents that could lead to fires when a power circuit from the power source side and a load circuit going to a load that operates by receiving power, such as lighting equipment and devices, air conditioning equipment and devices, freezing and refrigeration equipment and devices, or production equipment and devices, are electrically connected via power devices such as substation equipment, distribution boards, panel boards, lighting panels, power panels, control panels, and junction boxes, which are equipped with electrical equipment such as main breakers and earth leakage breakers.

[0003] The applicant of the present application has named a digital electric safety control system (Patent Document 1) "Descon" and has already put into practice a system that prevents electrical accidents that could lead to fires when a power circuit from the power source side and a load circuit going to a load that operates by receiving power, such as lighting equipment and devices, air conditioning equipment and devices, freezing and refrigeration equipment and devices, or production equipment and devices, are electrically connected via power devices such as substation equipment, distribution boards, panel boards, lighting panels, power panels, control panels, and junction boxes, which are equipped with electrical equipment such as a main breaker and a ground fault circuit interrupter.

[0004] The applicant of the present application has proposed a "Digital Electric Safety Control System" that prevents electrical accidents that could lead to fires or the like in electric power devices such as distribution boards, panel boards, lighting panels, power panels, control panels, and junction boxes, where the power supply side electric circuit from the power source side and the load side electric circuit leading to the load are electrically connected via electrical equipment installed inside a housing, and further prevents accidents that could damage the various electric power / electrical equipment / devices connected to the load side electric circuit (Patent Document 2).

[0005] The applicant of the present application has proposed a system, named "Death Control Operation Safety System," which prevents electrical accidents that could lead to fires by automatically switching on / off each of multiple loads connected to a load-side circuit, automatically reading the electricity meter for the load and automatically calculating the electricity usage, thereby saving labor, and detecting leakage current caused by loose bolts in bolt and screw tightening connections in electric power equipment, insufficient insertion into an outlet, or the accumulation of dirt in bolt and screw tightening connections, etc. (Patent Document 3).

[0006] [Patent Document 1] Patent No. 6732278 [Patent Document 2] Patent No. 6836234 [Patent Document 3] Patent No. 6991636 Summary of the Invention [Problem to be solved by the invention]

[0007] As the economy and industry expands on a global scale, information technology evolves in real time, becoming borderless, and human interaction advances. Along with the expansion of information, along with the advent of PCs, tablets, and smartphones, the quality and quantity of logistics is increasing in Japan and around the world. For example, the size and quality of logistics centers in building facilities has grown dramatically. In addition, information technology has led to the creation of cloud computing, data centers, material handling systems, semiconductor factories, inbound event halls, hotels, terminal buildings, skyscrapers, hotels, etc., and people's activities are becoming 24-hour, labor is being concentrated, robots are becoming more convenient, and the diversified features of outdoor facilities are appealing to various functions. In terms of lifestyle, the aging population, declining birthrate, single-person households, and skyscraper apartment buildings have led to infrastructure such as electrical equipment, machinery, and electrical appliances, and the number and quantity of items that utilize electricity are increasing dramatically, 365 days a year, 24 hours a day, making them more convenient.

[0008] On the other hand, the number of various electrical accidents is proportional to this. For example, the electricity consumed by buildings and facilities has increased dramatically and expanded, and there is no time when it is stopped for 24 hours. In particular, electricity is supplied by the electric power company to the substation equipment, including high-voltage transformers for lighting and power, low-voltage distribution panels for lighting and power in the system, distribution panels for the main line and system, main lines, electrical equipment, machinery equipment, terminal load connections, etc.

[0009] Transformers that convert high voltage electricity supplied by major power companies into low voltage electricity are installed on the second or third basement floor in some high-rise buildings and special facilities, for example. However, in logistics centers, factories, offices, hotels, terminal buildings, apartment complexes, and commercial facilities, due to recent linear rain bands and floods, low-lying areas, and national electrical equipment safety policies, foundations are often built on the roof or at a safe height on the ground floor, and major equipment such as the above-mentioned power receiving and transforming equipment, high voltage transformers for lighting and power, and low voltage distribution panels for lighting and power are often installed outdoors.

[0010] Furthermore, due to rising global outside temperatures, rising sea surface temperatures and high humidity, there is an indirect increase in load heat such as the enthalpy coefficient of the outside air temperature and air humidity heat quantity installed in the basement of a building, and the load heat due to the rise in outside air temperature of, for example, electric lighting and power transformers installed on the roof of a building or in the foundation structure on the ground floor, is increased. Even if the above-mentioned enclosure or building is equipped with ventilation and cooling equipment, the temperature of the electric lighting and power transformers will rise in proportion to the outside air temperature, and the temperature inside the transformer will rise, and if it approaches or exceeds the maximum allowable temperature of insulation materials type A to type H, there is a safety risk, as of now.

[0011] As mentioned above, the wide-ranging and diversifying nature of the economy, society, and social behavior has led to an increase in the amount of power used by low-voltage switchboards for lighting and power. If the approximate values ​​of the relevant switchboard, for example, the maximum current value, warning current value, or load factor are reached or exceeded, the safety risk of the relevant switchboard increases. Furthermore, as the amount of power passing through the relevant transformer increases, the electrical resistance increases proportionally, and the approximate maximum allowable temperature of the relevant transformer may be reached or exceeded. Conventionally, measures have been taken such as installing temperature sensors or thermostats on the transformer, and if an abnormality is detected, an email will be sent, etc., to deal with issues such as rising transformer temperatures. It is believed that a fundamental countermeasure is desired in Japan and around the world.

[0012] This invention aims to propose a system for monitoring and controlling power receiving and transforming equipment installed on an electric circuit from a power supply side to a plurality of loads, which monitors and controls the step-down distribution transformers, i.e., high-voltage transformers, installed in the power receiving and transforming equipment, and the electrical equipment installed on the electric circuit after the voltage has been stepped down by the high-voltage transformer in the power receiving and transforming equipment, thereby preventing the occurrence of electrical accidents that could lead to fires and other such accidents, and preventing the occurrence of accidents that could damage the various power and electrical equipment and devices that make up the plurality of loads, and further preventing the occurrence of electrical accidents and the like due to short circuits, sparks, tracking, etc. in the low-voltage distribution boards, distribution boards, control panels, system trunk lines, wiring, terminal electrical equipment, terminal load equipment, etc. in the power receiving and transforming equipment.

DETAILED DESCRIPTION OF THE INVENTION

[0024] The power receiving and transforming equipment, leakage current, and stray current digital safety control system of the present invention is a system that monitors and controls power receiving and transforming equipment 2 installed in an electric circuit 6 that runs from the power supply side to multiple loads 7 (Fig. 1). In this specification and drawings, the power receiving and transforming equipment, leakage current, and stray current digital safety control system of the present invention may be referred to as the "DESCON safety control system" or "DESCON".

[0025] Electrical substation equipment typically consists of a step-down distribution transformer and multiple pieces of electrical equipment installed on the electrical circuit after the voltage has been stepped down by the step-down distribution transformer. Examples of the multiple pieces of electrical equipment installed on the electrical circuit after the voltage has been stepped down by the step-down distribution transformer in electrical substation equipment include distribution boards, panelboards, lighting panels, power panels, control panels, remote control device panels, etc., as well as extension cords between devices and appliances or junction boxes for branch wiring connections, main breakers, earth leakage breakers, and circuit switches different from main breakers and earth leakage breakers, such as magnetic switches, power relays, and solid-state relays.

[0026] For ease of explanation, Figure 1 shows only the transformer 21 for step-down distribution, and the distribution board 22 and breaker 23 as electrical equipment installed in the electrical circuit after the voltage is stepped down by the transformer 21.

[0027] The multiple loads 7 deployed at the destination of the electric circuit 6 from the power supply side include, for example, prime movers, elevators, air conditioning equipment, ventilation equipment, lighting equipment, refrigerated and frozen cases, refrigerators and freezers, measuring instruments, computer equipment, surveillance cameras, medical equipment, communication equipment, etc., which are electric power and electrical devices and equipment that operate by receiving a supply of electric power, and which are deployed and used both inside and outside of buildings, and electric power and 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.

[0028] This also includes load device control devices such as the above-mentioned measuring instruments, computer equipment, surveillance cameras, medical equipment, etc., in which the power supply cannot be automatically cut off and the power supply to these loads is cut off after the power supply to the load device control device that controls these loads is cut off.

[0029] These multiple loads 7 are connected to the tip side of the electric circuit 6 in which the above-mentioned power receiving and transforming equipment 2 to be monitored is installed.

[0030] The heat resistance characteristics of the transformer of the power receiving and transforming equipment 2 are, for example, as follows.

[0031] In this specification and drawings, "transformer" may be abbreviated as "TR," "power receiving and substation equipment" may be abbreviated as "cubicle," and "AC instantaneous current detector" (Current Transformer) may be abbreviated as "CT."

[0032] The transformer 21 is classified into the following heat resistance classes according to the heat resistance characteristics of the insulating material used.

[0033] Insulating materials include insulating oil, SF6 gas, kraft paper, pressboard, mica, glass fiber, epoxy resin, silicone resin, and alkyd resin, and the maximum allowable temperatures for insulating oil and alkyd resin are specified. In addition, oil-filled transformers using the above-mentioned insulating materials are rated as heat-resistant class A, while molded transformers are rated as B, F, and H.

[0034] When used under standard operating conditions, transformers are designed so that the temperature rise limit of the windings (the difference between the winding temperature and the ambient temperature) is not exceeded and the temperature of each part of the insulation does not exceed the maximum allowable temperature of the heat resistance class. However, if the ambient temperature exceeds the maximum value of 40°C or if the transformer is operated under excessive overload, the maximum allowable temperature may be exceeded.

[0035] Since the lifespan of a transformer is most significantly affected by its maximum temperature, prolonged continuous operation above the maximum allowable temperature will shorten the expected lifespan of 30 years. The transformer's environment and configuration, for example, should be used at an altitude of 1,000 m or less; ambient temperature: indoors: -5°C to +40°C; outdoors: -20°C to +40°C; daily average temperature should not exceed 35°C, and annual average temperature should not exceed 20°C; circuit voltage waveform: the voltage waveform of the circuit to which the transformer is connected should be approximately sinusoidal; voltage balance of the three-phase circuit: the three-phase circuit to which the three-phase transformer is connected should be approximately balanced.

[0036] The reference winding temperature is determined as a reference temperature for calculating characteristic values ​​such as load loss and short-circuit impedance, since the resistance value changes depending on the temperature of the winding.

[0037] The heat resistance class and temperature of the insulating material of a TR (transformer) is 140K, as specified by the Japan Electrical Manufacturers' Association standard number: JEM 1310:2001, for the temperature rise limit and standard winding temperature (heat resistance class H) of dry-type transformers.

[0038] The reference winding temperature is determined as a reference temperature for calculating characteristics such as load loss and short-circuit impedance, since the resistance value changes depending on the winding temperature.

[0039] The boiling point of insulating oil in 6kV distribution oil-filled transformers (JIS C 4303 1999), oil-filled reactors (JIS 4902 2003), 6kV distribution molded transformers (JIS C 4306), and TRs is said to be around 290℃ to 340℃.

[0040] The power receiving and transforming equipment, leakage current and stray current digital safety control system of the present invention, i.e., the DESCON safety control system, is composed of a computer system 1 including a transformer detection temperature acquisition means 24, a distribution board instantaneous current value detection means 25, a breaker detection temperature acquisition means 26, a breaker instantaneous current value detection means 27, a leakage current and stray current detector ZCT 28, etc., which are installed in the power receiving and transforming equipment 2 to be monitored and controlled, and a server computer and other components connected to these via a network 5a (Figure 1).

[0046] Although not shown, the electrical equipment arranged in the circuit after the voltage is stepped down by the transformer 21 in the substation equipment 2 may be a distribution board, and a distribution board instantaneous current value acquisition means may be arranged on the distribution board as an instantaneous current value acquisition means for acquiring the instantaneous AC current value or instantaneous DC current value, which is the instantaneous current value flowing at an instantaneous time in the circuit of the distribution board.

[0047] In the embodiment shown in FIG. 1, the breaker instantaneous current value acquiring means 27 corresponds to an example of the breaker instantaneous current value detecting means of the present invention.

[0048] The distribution board instantaneous current value detection means 25 is connected to the circuit in the distribution board 22 and detects the instantaneous AC current value or instantaneous DC current value, which is the instantaneous current value flowing through the circuit in the distribution board 22 at an instantaneous time.

[0049] As the distribution board instantaneous current value detection means 25, a current sensor using an instrument current transformer called a CT (Current Transformer) or a DC instantaneous current meter using a Hall element can be used.

[0050] In Figure 1, the transformer detection temperature value acquisition means 24, distribution board instantaneous current value acquisition means 25, breaker detection temperature value acquisition means 26, breaker instantaneous current value acquisition means 27, leakage current / stray current detector (ZCT) 28, and computer system 1 are connected to each other via a wired or wireless network 5a such as the Internet or a dedicated line so that they can exchange information with each other.

[0051] In addition, the computer system 1 is connected to a plurality of manager terminals 3a, 3b, ... and a plurality of staff terminals 4a, 4b, 4c, ... via a wired or wireless network 5b such as the Internet or a dedicated line, so that information can be exchanged between them.

[0052] The above-mentioned manager terminals 3a, 3b, etc. are equipped with image information display means such as a monitor and can be configured as personal computers or the like on which the software for operating the system of the present invention is installed. Also, the above-mentioned staff terminals 4a, 4b, 4c, etc. can be configured as mobile terminals such as smartphones on which the application for operating the system of the present invention is downloaded.

[0053] The administrator terminals 3a, 3b, etc. and the staff terminals 4a, 4b, 4c, etc. are connected via a communication network 4b such as the Internet or a dedicated line so as to be able to exchange information with the computer system 1 consisting of a server computer that constitutes the power receiving and transforming equipment, leakage current, and stray current digital safety control system of the present invention, i.e., the DESCON safety control system.

[0054] The transformer detected temperature value acquiring means 24 is provided for the transformer 21 and acquires the transformer detected temperature value T T A process is performed to determine the temperature.

[0055] The transformer detected temperature value T is constantly monitored by the transformer detected temperature value acquisition means 24, which is made up of a temperature sensor or the like, and is output as digital information. T The temperature information is sent to the computer system 1 constituting the power receiving and transforming equipment, leakage current, and stray current digital safety control system (DESCON safety control system) of the present invention via a network 5a such as the Internet or a dedicated line. T The °C information is the transformer detection temperature value T TThe temperature in °C is associated with information identifying the transformer from which the temperature was acquired, and is stored together with information about the time of acquisition in a storage unit (not shown) of the computer system 1. The information about the time of acquisition is recorded in units of seconds, for example, such as the year, month, and day, hour, minute, and second.

[0056] The instantaneous current value i (amperes) (instantaneous AC current value or instantaneous DC current value) information, which is constantly monitored by the distribution board instantaneous current value acquisition means 25 and output as digital information, is delivered to the computer system 1 constituting the power receiving and transforming equipment, leakage current, and stray current digital safety control system (DESCON safety control system) of the present invention via a network 5a such as the Internet or a dedicated line. The delivered instantaneous current value i (amperes) is associated with information identifying the electrical equipment from which the instantaneous current value i (amperes) was acquired, and is stored in a memory unit (not shown) of the computer system 1 together with information about the acquisition time. The information about the acquisition time is recorded in units of seconds, for example, as the year, month, and day, hour, minute, and second.

[0057] The instantaneous time can be set anywhere between 1 / 50,000 seconds (=20μsec) and 1 / 100,000 seconds (=10μsec). Within this range, it can also be set to microseconds in proportion to the performance of the computer (PC) that makes up the DESCON safety control system.

[0058] Setting the instantaneous time unit for instantaneous time detection to microseconds between 1 / 50,000 seconds (=20 μsec) and 1 / 100,000 seconds (=10 μsec) is advantageous in that it allows for earlier detection of the risk of a tracking phenomenon occurring and enables necessary measures, such as cutting off the power supply, to be taken before the tracking phenomenon occurs.

[0059] The transformer temperature determination means 11 determines the transformer detected temperature value T TThe allowable temperature range that is preset for the heat resistance class that is classified according to the heat resistance characteristics of the insulating material used in the transformer 21 whose temperature is known in °C, and the transformer detection temperature value T T The temperature is compared with °C.

[0060] Information about the above-mentioned preset allowable temperature ranges to be used for comparison is stored in a storage unit (not shown) of the computer system 1.

[0061] The instantaneous current value determination means 12 performs a process of comparing the detected instantaneous current value with a preset allowable current value range for the electrical circuit of the distribution board 22, which is the electrical equipment whose instantaneous current value is acquired by the distribution board instantaneous current value acquisition means 25. In this case, information on the preset allowable current value range for the electrical circuit of the distribution board 22, which is the electrical equipment being monitored and is the comparison target, is stored in a memory unit (not shown) of the computer system 1.

[0062] The notification information sending means 13 described above performs processing to output notification information to the manager terminals 3a, 3b, ... used by the manager who manages the power receiving and transforming equipment 2 and / or the staff terminals 4a, 4b, 4c, ... used by the staff in charge of managing the power receiving and transforming equipment 2.

[0063] The notification information level determination means 14 performs a process of determining the level of the notification information output by the notification information sending means 13 based on the comparison results by the transformer temperature determination means 11 and the comparison results by the instantaneous current value determination means 12.

[0064] The determination process performed by the notification information level determination means 14 includes the following. <First Determination Process> The comparison result by the transformer temperature determination means 11 is the above-mentioned transformer detected temperature value T TWhen °C reaches the warning temperature in the above-mentioned allowable temperature range, and the comparison result by the instantaneous current value determination means 12 does not reach the warning current value in the above-mentioned allowable current value range, a determination is made to set the level of the above-mentioned notification information to warning information.

[0065] The notification information sending means 13 outputs the notification information at the level determined by the notification information level determining means 14. That is, the notification information sending means 13 performs processing to output the above-mentioned attention-calling information as notification information to the manager terminals 3a, 3b, ... and / or the person in charge terminals 4a, 4b, 4c, ... based on the above-mentioned determination processing.

[0066] When the notification information sending means 13 outputs the warning information in this manner, the notification information sending means 13 outputs the transformer detected temperature value T T An embodiment can be made in which information regarding °C and information regarding the instantaneous current value i (amperes) in the electrical equipment that was the subject of the above-mentioned judgment by the notification information level judgment means 14 (in the above case, the distribution board 22) are attached to the warning information to be output.

[0067] As described above, the transformer detection temperature value T T The °C information is the transformer detection temperature value T T The °C is associated with information identifying the transformer from which it was acquired and stored in a memory unit (not shown) of the computer system 1 together with information regarding the time of acquisition, and similarly, the delivered instantaneous current value i (amperes) is associated with information identifying the electrical equipment from which the instantaneous current value i (amperes) was acquired and stored in a memory unit (not shown) of the computer system 1 together with information regarding the time of acquisition.

[0068] Using this information, the notification information sending means 13 outputs the notification information including the transformer detected temperature value T T ° C. and information about the instantaneous current value i (amperes) in the electrical equipment that is the target of the determination by the notification information level determination means 14 (distribution board 22 in the above case) are attached.

[0069] <Second Determination Process> The comparison result by the transformer temperature determination means 11 is the above-mentioned transformer detected temperature value T T When °C does not reach the warning temperature in the above-mentioned allowable temperature range, and the comparison result by the instantaneous current value determination means 12 reaches the warning current value in the above-mentioned allowable current value range, a determination is made to set the level of the above-mentioned notification information to the above-mentioned warning information.

[0070] The notification information sending means 13 outputs the notification information at the level determined by the notification information level determining means 14. That is, the notification information sending means 13 performs processing to output the above-mentioned attention-calling information as notification information to the manager terminals 3a, 3b, ... and / or the person in charge terminals 4a, 4b, 4c, ... based on the above-mentioned determination processing.

[0071] In this case, as described above, the notification information (attention information) output by the notification information sending means 13 includes the transformer detected temperature value T T An embodiment can be made in which information regarding °C and information regarding the instantaneous current value i (amperes) in the electrical equipment that is the subject of judgment by the notification information level judgment means 14 (in the above case, distribution board 22) are attached.

[0072] <Third Determination Process> The comparison result by the transformer temperature determination means 11 is the above-mentioned transformer detected temperature value T TWhen °C reaches the warning temperature in the above-mentioned allowable temperature range and the comparison result by the instantaneous current value determination means 12 is that it has reached the warning current value in the above-mentioned allowable current value range, a determination is made to set the level of the above-mentioned notification information to alarm notification information, which is a type of notification information different from the above-mentioned warning information.

[0073] The notification information sending means 13 outputs the notification information at the level determined by the notification information level determining means 14. That is, the notification information sending means 13 performs processing to output the above-mentioned alarm notification information as notification information to the manager terminals 3a, 3b, ... and / or the person in charge terminals 4a, 4b, 4c, ... based on the above-mentioned determination processing.

[0074] In this case, as described above, the notification information (alarm notification information) output by the notification information sending means 13 includes the transformer detected temperature value T T An embodiment can be made in which information regarding °C and information regarding the instantaneous current value i (amperes) in the electrical equipment that is the subject of judgment by the notification information level judgment means 14 (in the above case, distribution board 22) are attached.

[0075] <Fourth Determination Process> The comparison result by the transformer temperature determination means 11 is the above-mentioned transformer detected temperature value T T When °C reaches an alarm temperature, which is a temperature value higher than the above-mentioned warning temperature in the above-mentioned allowable temperature range, or when the comparison result by the instantaneous current value determination means 12 is that it reaches an alarm current value, which is a current value higher than the above-mentioned warning current value in the above-mentioned allowable current value range, a determination is made to set the level of the above-mentioned notification information to the above-mentioned alarm notification information.

[0076] The notification information sending means 13 outputs the notification information at the level determined by the notification information level determining means 14. That is, the notification information sending means 13 performs processing to output the above-mentioned alarm notification information as notification information to the manager terminals 3a, 3b, ... and / or the person in charge terminals 4a, 4b, 4c, ... based on the above-mentioned determination processing.

[0077] In this case, as described above, the notification information (alarm notification information) output by the notification information sending means 13 includes the transformer detected temperature value T T An embodiment can be made in which information regarding °C and information regarding the instantaneous current value i (amperes) in the electrical equipment that is the subject of judgment by the notification information level judgment means 14 (in the above case, distribution board 22) are attached.

[0078] The above-mentioned allowable temperature range is arbitrarily set in advance within a range that can achieve the object of the present invention for each heat resistance class (e.g., Class A insulation, Class E insulation, Class B insulation, Class F insulation, Class H insulation) that is classified according to the heat resistance characteristics of the insulating material used in the transformer 21 to be monitored, taking into consideration the allowable maximum temperatures that are set for each class, as is well known, that is classified according to the heat resistance characteristics of the insulating material used in the transformer 21 to be monitored.

[0079] For example, if the maximum allowable temperature of the transformer 21 to be monitored is 130°C and the maximum allowable current value is 1718A (amperes), the allowable temperature range that can be set in advance as desired can be 120°C to 135°C within the range that can achieve the object of the present invention, and similarly, the warning temperature and alarm temperature that can be set in advance as desired can be set to 130°C and 135°C, respectively.

[0080] The above-mentioned allowable current value range that is pre-set for the electrical circuit of the electrical equipment whose instantaneous current value is acquired by the instantaneous current value acquisition means can be, for example, a current value range that is pre-set according to the cable size of the electrical circuit of the electrical equipment whose instantaneous current value is acquired by the instantaneous current value acquisition means.

[0081] For example, the allowable current value range that is pre-set corresponding to the cable size of the electrical circuit of the electrical equipment whose instantaneous current value is acquired by the instantaneous current value acquisition means can be 1.25 times or less of the rated current set for the electrical circuit of that cable size, the warning current value that is pre-set arbitrarily can be 1.20 times or less of the rated current set for the electrical circuit of the cable size of the electrical equipment whose instantaneous current value is acquired by the instantaneous current value acquisition means, the alarm current value that is pre-set arbitrarily can be 1.25 times or less of the rated current set for the electrical circuit of the cable size of the electrical equipment whose instantaneous current value is acquired by the instantaneous current value acquisition means, etc.

[0082] In this way, the power receiving and transforming equipment leakage current and stray current digital safety control system of the present invention constantly monitors the temperature of the transformer 21 for stepping down and distributing power in the power receiving and transforming equipment, and the instantaneous current value of the circuit in electrical equipment such as distribution boards and panelboards that are installed in the circuit after the voltage is stepped down by the transformer 21 in the power receiving and transforming equipment.

[0083] When only one of them satisfies the specified warning information output conditions, warning information is output to the administrator or person in charge; when only one of them satisfies the specified alarm information output conditions that require a higher level of management and control than the above-mentioned warning information output conditions, alarm information, which is a different type of warning information from the above-mentioned warning information, is output to the administrator or person in charge; and when both of them satisfy the above-mentioned specified warning information output conditions, the above-mentioned alarm information is output to the administrator or person in charge.

[0084] In this way, by constantly monitoring the temperature of the transformer 21 for step-down distribution in the power receiving and transforming equipment and the instantaneous current values ​​of the electrical circuits in electrical equipment such as distribution boards and distribution panels that are installed in the electrical circuits after the voltage has been stepped down by the transformer 21 in the power receiving and transforming equipment, and when either or both of them simultaneously reach the above-mentioned warning information output conditions or alarm information output conditions, different types of warning information and alarm information are output to the manager or person in charge, it is possible to prevent the occurrence of electrical accidents that lead to fires and the like, and to prevent the occurrence of accidents that damage the various power and electrical equipment and devices that are multiple loads, and further to prevent the occurrence of electrical accidents due to short circuits, sparks, tracking, etc. in the low-voltage distribution boards, distribution boards, control panels, main lines of the system, wiring, terminal electrical equipment, terminal load equipment, etc. in the power receiving and transforming equipment.

[0085] The above-mentioned power supply automatic cut-off possibility determination means 15 performs a process of determining whether each of the multiple loads 7 to which current is supplied via the electrical equipment (distribution board 22 in the above) whose instantaneous current value i (amperes) has been acquired by the instantaneous current value acquisition means (distribution board instantaneous current value acquisition means 25 in the above) that has been the subject of comparison by the instantaneous current value determination means 12 is a load for which power supply automatic cut-off is possible when the notification information level determination means 14 determines that the level of the notification information is the alarm notification information.

[0086] Information used in this determination process, such as whether each of the plurality of loads 7 is a load for which automatic power supply interruption is possible, is stored in a storage unit (not shown) of the computer system 1.

[0087] Furthermore, the first power supply cutoff means 16 performs processing to automatically cut off the power supply to the load 7 for which the automatic power supply cutoff possibility determining means 15 has determined that automatic power supply cutoff is possible.

[0088] For example, in order to automatically cut off the power supply to a load 7 that has been determined by the automatic power supply cut-off feasibility determination means 15 to be capable of automatic power supply cut-off, the processing operation unit of the computer system 1 sends predetermined signal information to the power receiving and transforming equipment 2 via the above-mentioned network 5a, and instructs devices such as the breaker 23 that make up the power receiving and transforming equipment 2 to execute the above-mentioned automatic power supply cut-off.

[0089] Furthermore, the second power supply cut-off means 17 cuts off the power supply to the load device control device that controls the load 7 that has been determined by the power supply automatic cut-off possibility determination means 15 to be unable to automatically cut off the power supply, and then performs processing to automatically cut off the power supply to the load 7.

[0090] For example, the processing operation unit of the computer system 1 cuts off the power supply to the load device control device that controls the load 7 that has been determined by the power supply automatic cut-off feasibility determination means 15 to be unable to automatically cut off the power supply, and then sends specified signal information to the power receiving and transforming equipment 2 via the above-mentioned network 5a to automatically cut off the power supply to the load, and instructs equipment such as the breaker 23 that constitutes the power receiving and transforming equipment 2 to cut off the power supply to the above-mentioned load device control device, and then automatically cut off the power supply to the load.

[0091] The above-mentioned power receiving and transforming equipment leakage current and stray current digital safety control system can be made into a system equipped with a tracking detection function by converting the analog instantaneous AC current value or analog instantaneous DC current value detected by the above-mentioned distribution board instantaneous current value detection means 25 into an analog voltage value, converting the analog voltage value into a digital voltage value, and converting the digital voltage value into a current value to detect abnormal currents.

[0092] The process of converting the analog instantaneous AC current value or analog instantaneous DC current value detected by the distribution board instantaneous current value detection means 25 into an analog voltage value, converting the analog voltage value into a digital voltage value, and converting the digital voltage value into a current value to detect abnormal current can be executed by the processing operation unit of the computer system 1 based on the analog instantaneous current value (analog instantaneous AC current value or analog instantaneous DC current value) acquired by the computer system 1. Alternatively, a microcomputer can be attached to the distribution board instantaneous current value detection means 25, and the above-mentioned process can be executed by the microcomputer.

[0093] When the electrical equipment whose instantaneous current value is acquired by the above-mentioned instantaneous current value acquisition means is a circuit breaker (breaker) 23, or when a circuit breaker (breaker) 23 is arranged in addition to the electrical equipment whose instantaneous current value is acquired by the instantaneous current value acquisition means in the power receiving and transforming equipment 2 in an electric circuit after being stepped down by the transformer 21, by further providing a breaker detection temperature value acquisition means 26 that monitors the temperature rise due to Joule heat of the connection terminal block of the electric circuit in the circuit breaker (breaker) 23, it is possible to create a power receiving and transforming equipment, leakage current, and stray current digital safety control system with a Joule heat detection function.

[0094] When the configuration is provided with a circuit breaker (breaker) 23, a breaker detection temperature value acquisition means 26 is provided for the circuit breaker (breaker) 23 to constantly monitor the temperature of the terminal block at the connection point of the electrical circuit in the circuit breaker (breaker) 23, and the temperature of the terminal block at the connection point of the electrical circuit in the circuit breaker (breaker) 23 is constantly monitored.

[0095] The connection terminal block detected temperature value information is constantly monitored by a breaker detected temperature value acquisition means 26 consisting of a temperature sensor or the like, and is output as digital information.The information is delivered to a computer system 1 that constitutes the power receiving and transforming equipment, leakage current, and stray current digital safety control system (DESCON safety control system) of the present invention via a network 5a such as the Internet or a dedicated line.

[0096] Since the temperature information of the connection terminal block of the electrical circuit in the circuit breaker 23 is due to Joule heat, the power receiving / transformation equipment, leakage current, and stray current digital safety control system consisting of the computer system 1 is configured to have a Joule heat detection function by monitoring the acquired connection terminal block detected temperature value information.

[0097] In addition, a breaker instantaneous current value detection means 27 for monitoring overcurrent in the circuit in the breaker 23 can be provided in the breaker 23, so that the overcurrent in the circuit in the breaker 23 can be constantly monitored.

[0098] The connection terminal block detected overcurrent value information, which is constantly monitored by the breaker instantaneous current value detection means 27 and output as digital information, is delivered to the computer system 1 that constitutes the power receiving and transforming equipment, leakage current, and stray current digital safety control system (DESCON safety control system) of the present invention via a network 5a such as the Internet or a dedicated line.

[0099] This allows the power receiving / transformation equipment, leakage current, and stray current digital safety control system of the present invention to be configured with an overcurrent monitoring function by monitoring the acquired connection terminal block detected overcurrent value information.

[0100] As the breaker instantaneous current value detection means 27, a current sensor using an instrument current transformer called a CT (Current Transformer) or a DC instantaneous current meter using a Hall element can be used, similar to the distribution board instantaneous current value detection means 25 described above.

[0101] The instantaneous time can be set arbitrarily between 1 / 50,000 seconds (=20 μsec) and 1 / 100,000 seconds (=10 μsec). Within this range, it can also be set to microseconds in proportion to the performance of the computer (PC) that makes up the DESCON safety control system.

[0102] Furthermore, a leakage current / stray current detector ZCT (Zero-phase Current Transformer) 28 that monitors the leakage current of the circuit in the circuit breaker 23 may be provided in the circuit breaker 23, so that the leakage current / stray current of the circuit in the circuit breaker 23 can be constantly monitored.

[0103] The leakage current value information, which is constantly monitored by the leakage current / stray current detector 28 and output as digital information, is delivered to the computer system 1 that constitutes the power receiving / transforming equipment leakage current / stray current digital safety control system (DESCON safety control system) of the present invention via a network 5a such as the Internet or a dedicated line.

[0104] This allows the power receiving and transforming equipment leakage current and stray current digital safety control system to be configured with a leakage current and stray current monitoring function by monitoring the acquired leakage current and stray current value information.

[0105] For example, leakage currents can be stored as caution leakage currents and warning leakage currents, and stray currents can be stored as caution stray currents and warning stray currents, and leakage currents, stray currents, etc. can be stored, for example, by second, minute, hour, day, week, 10 days, month, 3 months, 6 months, year, etc. by season, or by 1 year ago, 2 years ago, 3 years ago, 5 years ago, n years ago, etc., and a form can be provided in which a means (for example, database processing unit 18) is provided to construct a database (not shown) in the computer system 1.

[0106] That is, the above-mentioned transformer detected temperature value T TThe computer system 1 is configured to have a database processing unit that stores one or more of the following information in a database: information on temperature in °C, information on the instantaneous DC current value detected by the distribution board instantaneous current value detection means 25 which is an instantaneous current value detection means, and information on the leakage current and stray current values ​​grasped by the leakage current and stray current value detector ZCT.

[0107] The transformer detected temperature value T acquired by the transformer detected temperature value acquisition means 24 T The °C information is the transformer detection temperature value T T °C is associated with information identifying the acquired transformer and stored in a memory unit (not shown) of the computer system 1 together with information regarding the acquisition time. Information on the instantaneous current value i (amperes) (instantaneous AC current value or instantaneous DC current value) acquired by the distribution board instantaneous current value acquisition means 25 is associated with information identifying the electrical equipment from which the instantaneous current value i (amperes) was acquired and stored in a memory unit (not shown) of the computer system 1 together with information regarding the acquisition time. Information regarding the leakage current and stray current values ​​detected by the leakage current and stray current detector ZCT is associated with information identifying the breaker 23 and stored in a memory unit (not shown) of the computer system 1 together with information regarding the acquisition time.

[0108] Therefore, these can be put into a database using the database creation means described above (for example, the database processing unit 18), and when the computer system 1 receives an information request from the administrator terminals 3a, 3b, ..., or the staff terminals 4a, 4b, 4c, ... via the network 5b, the information corresponding to the information request can be extracted from the database and sent from the computer system 1 via the network 5b to the administrator terminals 3a, 3b, ..., or the staff terminals 4a, 4b, 4c, ... that made the information request.

[0109] That is, the computer system 1 is configured to have a database information output means 19 which, when it receives an information request from the manager terminal 3a, 3b, ... or the person in charge terminal 4a, 4b, 4c, ..., extracts information corresponding to the information request from the database and sends it to the manager terminal 3a, 3b, ... or the person in charge terminal 4a, 4b, 4c, ... that made the information request.

This low voltage electricity for lighting and power is connected to the transformers of each system in, for example, a building facility, and is connected to a distribution board equipped with a measuring device, for example, a CT that measures current, and a leakage current measuring device, for example, a ZCT that detects leakage current, and then energizes each area, floor, etc., of the building facility, and the electrical equipment and load equipment. The power receiving and transforming equipment, leakage current, and stray current digital safety control system detects the temperature of the lighting and power transformers that supply and transmit power to the lighting and power electrical equipment and load equipment, and can input and store the maximum allowable temperature of the transformer's insulating material, for example, 105°C for type A, 120°C for type E, 130°C for type B, 155°C for type F, and 180°C for type H, etc., depending on the heat-resistant insulation type.

[0152] For example, if the maximum allowable temperature for insulation type A is 105°C and a predetermined safety factor of 0.98 is used, the DESCON Safety Control System can be configured to send an alert to the relevant person's PC, tablet, smartphone, etc. via voice, image, email, etc., with information such as the relevant customer name, building / facility name, location, relevant light, power transformer name, etc., along with information such as the warning temperature being 102.9°C and the warning temperature rate being 98.0%.

[0153] Also, for example, if the maximum allowable temperature for insulation type A is 105°C, and the predetermined allowable maximum temperature of 105°C is exceeded, for example, the detected temperature is 132°C, and the temperature rise rate = (detected temperature 132°C / maximum allowable temperature 105°C) = 125.7%, an alert can be sent by email or the like, along with the relevant customer name, building facility, light / power number, transformer, etc.

[0154] In addition, the DESCON Safety Control System has a boiling point of 290°C to 340°C for insulation oil of insulation type A. For example, if the temperature of a transformer of insulation type A, for example, whose boiling point is 290°C, and the safety factor is set arbitrarily in advance, say 0.6, then when it detects an insulation temperature of (290°C x 0.5) = 145°C, it will automatically shut off the circuits of the electrical equipment and load equipment systems in each distribution board of the system of the distribution board of the relevant transformer, for example, in the order of the circuit breakers of the distribution board, using an arbitrarily set program in advance, and will continue to shut off sequentially until the temperature drops to the maximum allowable temperature of 105°C. When the boiling point alarm temperature is reached, an alert will be sent to the relevant parties via their PCs, tablets, voice, image, email, etc., with details of the automatic shutdown of the relevant equipment, including the customer name, building facilities, transformer distribution board, system distribution board, electrical equipment, load equipment, etc.

[0155] <Heat resistance class and temperature of insulating materials for transformer in power receiving and transforming equipment> Notwithstanding the above, the DESCON Safety Control System determines whether the (1) maximum allowable temperature of the insulation type of lighting and power transformers is 105°C for type A, 120°C for type E, 130°C for type B, 155°C for type F, and 180°C for type H, and whether the (2) detected temperature of the temperature sensor installed in the TR exceeds the corresponding maximum allowable temperature or is below the maximum allowable temperature, or whether the (3) maximum allowable temperature value of each of the above types A to H is used as a reference. For example, (4) a safety temperature coefficient of 0.97 is arbitrarily set in advance as the safety caution temperature. For example, (5) the TR of Class A is = (Class A maximum allowable temperature 105°C x 0.97) = caution temperature 102°C. (6) When a caution temperature is detected, an alert can be sent to the PC, tablet, smartphone, etc. of the relevant person, along with, for example, the relevant customer name, building / facility name, location, relevant light, power transformer name, etc., along with "Caution temperature 102.0°C," "Caution temperature rate 97.0%, etc."

[0156] In addition, the system terminal's electrical equipment load equipment name, etc. is sent as an alert in the form of voice, numerical values, images, etc., and the alert ringtone is sent continuously until the relevant person confirms and resets, preventing the relevant person from missing the confirmation. (7) If the detected temperature exceeds the "maximum allowable temperature 105°C", for example, 132°C, (8) the alarm cutoff temperature coefficient, which is set in advance, is, for example, 1.10, so that the alarm cutoff temperature = (maximum allowable temperature 105°C x alarm cutoff temperature coefficient 1.10) = 112.2, and (9) the automatic cutoff temperature = (detected temperature 132°C - alarm (10) Automatic tripping rate = 1 - (alarm tripping temperature 112.2℃ / detection temperature 132℃) = 15% of the tripping temperature (tripping temperature 112.2℃) = 19.8℃. (11) The tripping order of the relevant distribution board, distribution board circuits, terminal load equipment, electrical equipment, etc., which has been arbitrarily set in advance and which can be tripped without causing any problems, is determined, and the electrical equipment, etc. is automatically tripped. By reducing the (12) current value that energizes the relevant TR, the TR temperature decreases in proportion to the current value due to the reduction in the thermal load of the electrical resistance, and (13) the TR temperature decreases. When the power receiving / transforming equipment, leakage current, and stray current digital safety control system detects the above-mentioned detection temperature of 132°C, the alarm temperature rise rate = (detection temperature 132°C / maximum allowable temperature 105°C) = 121%, and an alert can be sent to the PC, tablet, smartphone, etc. of the relevant person, including, for example, the relevant customer name, building / facility name, location, relevant light, power transformer name, etc., along with the alarm temperature of 132°C, the alarm temperature rise rate of 121.0%, etc.

[0157] Notwithstanding the above, the DESCON Safety Control System determines whether the (1) maximum allowable temperature for the insulation type of lighting and power transformers is 105°C for type A, 120°C for type E, 130°C for type B, 155°C for type F, and 180°C for type H, and whether the (2) detected temperature of the temperature sensor installed in the TR exceeds the corresponding maximum allowable temperature or is equal to or lower than the maximum allowable temperature, or whether the (3) maximum allowable temperature of each of the above types A to H is higher than the corresponding maximum allowable temperature. Based on this, for example, (4) a safety temperature coefficient of 0.97 is arbitrarily set in advance as the safety caution temperature. For example, (5) the TR of Class A is = (Class A maximum allowable temperature 105°C x 1.0) = caution temperature 105°C. (6) When a caution temperature is detected, an alert can be sent to the PC, tablet, smartphone, etc. of the relevant person, including, for example, the relevant customer name, building / facility name, location, relevant light, power transformer name, etc., along with the caution temperature of 105.0°C and the caution temperature rate of 100.0%.

[0158] In addition, the system terminal sends an alert with the name of the electrical equipment load equipment, etc., as a voice, numerical value, image, etc., and the alert ringtone is sent continuously until the relevant person confirms and resets it, preventing the relevant person from missing the confirmation. (7) If the detected temperature is the maximum allowable temperature of 105°C or higher, for example, 132°C, (8) the maximum allowable temperature of 105°C or higher, which is arbitrarily set in advance, is set as the alarm cutoff temperature. (9) Automatic cutoff temperature = (detected temperature 132°C - alarm cutoff temperature 105°C) = 27.0°C, (10) Automatic cutoff rate = 1 - (alarm cutoff temperature 105.0°C / detected temperature (132°C) = 20% is automatically shut off, and the order of (11) shutoff of the relevant distribution board, distribution board circuits, etc., terminal load equipment, electrical equipment, etc. is determined, and by automatically shutting off the relevant distribution board, control panel, circuits, etc., terminal load equipment, electrical equipment, etc. that can be shut off without causing any problems, the (12) current value passing through the relevant TR is reduced, and the TR temperature is reduced in proportion to the current value due to the reduction in the thermal load of the electrical resistance, (13) and the TR temperature is reduced to below the allowable maximum temperature of 105°C.

[0159] When the DESCON Safety Control System detects the detection temperature of 132°C, the alarm temperature rise rate = (detection temperature 132°C / maximum allowable temperature 105°C) = 121%, and an alert can be sent to the relevant person's PC, tablet, smartphone, etc., displaying, for example, the relevant customer name, building / facility name, location, relevant light, power transformer name, etc., along with the alarm temperature of 132°C and the alarm temperature rise rate of 121.0%, etc.

[0160] As described above, the DESCON safety control system (14) automatically shuts off the distribution boards, control panels, circuits, etc. of the TR system when the detected temperature is 132°C, as well as terminal load equipment, electrical equipment, etc., and (15) automatically shuts off 20% of them using a predetermined program until the temperature drops to the maximum allowable temperature of 105.0°C. If the temperature does not drop further to the maximum allowable temperature of 105.0°C, the system will automatically shut off the relevant distribution boards, control panels, circuits, etc., terminal load equipment, electrical equipment, etc., until the temperature drops to 105°C. Conversely, the system can be configured to have a means to stop the automatic shutoff if the alarm shutoff temperature of 105.0°C is reached even while the system is shutting down using the program.

[0161] The DESCON Safety Control System can be configured to automatically shut off terminal load equipment, electrical devices, etc., such as the relevant main distribution board, additional distribution board, circuits, etc., terminal load equipment, electrical devices, etc., that can be shut off without causing any problems by setting a predetermined alarm shutoff temperature of 105°C or higher, for example, (17) the current value when the detection temperature is 132°C, and (18) the detection current value is 938A, with an automatic shutoff rate of 15%, (19) for the relevant distribution board, control panel, circuit, etc., and terminal load equipment, electrical devices, etc., for example, with an automatic shutoff rate of 20.5% at a detection current value of 938A, (20) with an automatic shutoff rate of 20.5%, (21) the detection shutoff current A = (detection current 938AX automatic shutoff rate 20.5%) = 192.9A.

[0162] The DESCON Safety Control System can be configured to display, for example, the customer name, building / facility name, location, relevant light and power transformer name, as well as an alarm temperature of 132°C, alarm temperature rise rate = (detected temperature 132°C / maximum allowable temperature 105°C) = 126.0%, on the PC, tablet, smartphone, etc. of the relevant person, and send an alert.

[0163] The DESCON Safety Control System (1) automatically shuts off various types of equipment and electrical devices, such as those used in logistics centers, large freezers, refrigerators, and other products and manufacturing facilities where many people gather, terminal buildings, hotels, and other similar facilities, as well as data centers for important data, research and test results, infrastructure substations, and transportation trains and ships, etc., using computer programs such as AI and IoT. (2) When the terminal equipment and electrical devices are automatically shut off by a predetermined program, the terminal equipment and electrical devices are automatically shut off by a predetermined program. (3) When the terminal equipment and electrical devices are automatically shut off by a predetermined program, the terminal equipment and electrical devices are automatically shut off by a predetermined program. The DESCON safety control system, which is composed of remote devices for each system, such as control panels, main lines, circuits, breakers, etc., as well as cloud servers, LANs, etc., uses an emergency response protection program via remote devices for each system, cloud servers, LANs, etc. (4) The remote devices, such as the relevant distribution boards, distribution boards, control panels, etc., send a signal to the protection stop device, and the control equipment, etc., as a whole or selected terminal equipment, etc., is safely protected, and has the function of shutting down by program, and can be configured to have a means for controlling the stop function normally and safely, and a means for confirming the stop signal.

[0164] The DESCON Safety Control System states that the boiling point of insulating oil for insulation type A is approximately 290°C to 340°C, but if the temperature of an insulation type A transformer, for example, is 290°C and the safety factor is set arbitrarily in advance, for example 0.6, then when it detects an insulation temperature of (290°C x 0.5) = 145°C, it will automatically shut off the circuits of the electrical equipment and load equipment systems in each distribution board of the system of the distribution board for that transformer, for example, in an arbitrarily predetermined order of the circuit breakers in the relevant distribution boards, until the temperature drops to the maximum allowable temperature of 105°C, and it can be configured to send a boiling point warning temperature alert to the relevant parties' PCs, tablets, voice, image, email, etc.

[0165] In the DESCON safety control system, for example, the No. 1 light transformer has (1) a capacity of 200 KVA, (2) a maximum current of 952 A, (3) a thermal relay of 3.9 A, (4) an alarm load current of 780 A, (5) a load equipment capacity of 164 KW, and (6) a load factor of 82%. (7) The current of the No. 1 light, which is arbitrarily determined in advance, of 780 A is designed and constructed as the alarm load current. (8) For example, the alarm load current of 780 A and the load factor of 82% are arbitrarily determined in advance. With a safety factor of 0.95, (9) the caution current = 780AX0.95) = 741.0A, and (10) the current load rate = (741.0 / 952.0) = 77.8%. If a detection current of 741.0A is detected, (10) an alert can be sent to the relevant person via their PC, tablet, voice, image, email, etc., along with the name of the building or facility, location, name of the relevant switchboard or distribution board, etc., stating that the caution current is 741A and the current load rate is 77.8%.

[0166] In the DESCON safety control system, for example, the No. 1 light transformer has (1) a capacity of 200 kVA, (2) a maximum current of 952 A, (3) a thermal relay of 3.9 A, (4) an alarm load current of 780 A, (5) a load equipment capacity of 164 kW, and (6) a load factor of 82%. (7) The No. 1 light current of 780 A, which is arbitrarily set in advance, is designed and constructed as the alarm load current. (8) For example, if the alarm load current exceeds the arbitrarily set alarm load current of 780 A and the load factor exceeds 82%, for example, the detection current is 801 A, and the load factor = (detection current 800 A / maximum current 952 A) = 84.0%. (9) When a detected current of 800A exceeds a preset arbitrary 780A, (detected current 800A - set current 780A) = 20A is automatically cut off at the relevant No. 1 electric light distribution panel, for example, 20A at circuit No. 6 of distribution panel No. 1 for which a cutoff circuit has been set in advance, thereby reducing the detected current to 780A. (10) An alert can be sent to the relevant person's PC, tablet, voice, image, email, etc., along with, for example, the name of the building or facility, location, name of the relevant distribution panel or distribution panel, etc., and that the alarm current is 801A, the current load rate is 84.0%, and the alarm has been cut off.

[0167] In the DESCON safety control system, for example, the No. 1 power transformer has (1) a capacity of 500 KVA, (2) a maximum current of 1718 A, (3) a thermal relay of 4.5 A, (4) an alarm load current of 1350 A, (5) a load equipment capacity of 393 KW, and (6) a load factor of 79%. (7) The No. 1 power transformer current of 1350 A, which is arbitrarily determined in advance, is designed and constructed as the alarm load current. (8) For example, the safety control system is designed and constructed as an arbitrary predetermined value of the alarm load current of 1350 A and the load factor of 79%. Multiplying by the total coefficient of 0.95, (9) safe current = (1350AX0.95) = 1282.5 A, and (10) safe load factor = (1282.5 / 1718.0) = 74.7%. If a detection current of 1282.5 A is detected, (10) an alert can be sent to the relevant person's PC, tablet, voice, image, email, etc., along with information such as the name of the building or facility, location, and name of the relevant switchboard or distribution board, stating that the caution current is 1282.5 A and the current load factor is 74.7%.

[0168] The DESCON safety control system, for example, for the No. 1 power transformer, has the following parameters: (1) capacity of 500 KVA, (2) maximum current of 1718 A, (3) thermal relay of 4.5 A, (4) alarm load current of 1350 A, (5) load equipment capacity of 393 KW, (6) load rate of 79%, and (7) the current of 1350 A for the No. 1 power, which is arbitrarily determined in advance, is designed and constructed as the alarm load current. (8) For example, if the alarm load current of 1350 A and the load rate of 79% are exceeded, for example, the detected current is 1430 A, and the load rate = (detected current 1450 A / maximum current 1718 A) = 84.4%. (9) The detected current of 1450 A, which exceeds the arbitrarily set 1350 A in advance, will automatically cut off 100 A of Circuit No. 6 of Sub - panel No. 1 of the corresponding No. 1 power distribution panel (where the cut - off circuit is determined in advance), reducing the detected current to 1350 A. It is characterized by control means. (10) It can be in a form that alerts, for example, to relevant personnel's PCs, tablets, voice, images, emails, etc., including building / facility names, locations, corresponding distribution panel / sub - panel names, etc., along with the alarm current of 1450 A and the current load rate of 84.4% when the alarm is cut off.

[0169] The DESCON safety control system can handle the following facilities and their corresponding electrical equipment, air - conditioning and ventilation equipment, lighting, elevators, etc. For example, in buildings and facilities such as warehouses, logistics centers, factories for the production of goods and products, large - scale refrigerators, refrigerators, and other commercial facilities where many people gather, terminal buildings, hotels, offices, apartment buildings, etc., research institutes, data centers, event halls, etc., outdoor facilities such as power plants, substations, water purification plants, etc., transportation facilities such as trains, ships, etc., and various electrical equipment in large - scale buildings and facilities. It is a system that can handle each of the above - mentioned facilities, as well as main lines, circuits, breakers, terminal load facilities, electrical equipment, etc.

[0170] <Regarding the composition and functions of the A. electric lights, power transformers, B. low - voltage distribution panels for electric lights and power, and C. sub - panels and terminal load facilities of the power receiving and transforming equipment (hereinafter referred to as cubicles) by the DESCON safety control system> For example, the configuration of the main distribution board + additional distribution board for the lighting TR of a building's power receiving and transforming equipment, including three lighting transformers (hereinafter referred to as TR) and four power transformers (hereinafter referred to as TR), with voltage, TR insulation type being Class A, capacity, thermal relay (thermal relay), circuit current, and facility capacity, is as follows:

[0171] In the case of power receiving and transforming equipment, (1) the capacity of the transformers for lighting and power is determined based on the size of the building or facility, such as area and floors, and the purpose of the building or facility. For example, the load capacity of terminal equipment, electrical equipment, lighting, and power equipment for each system is determined. (2) The maximum load capacity demand consumed by the load capacity is determined based on the safety factor for the corresponding lighting. Generally, the load factor is about 70-75% for lighting and about 60-65% for power. Therefore, a protective function is installed on the secondary side of the transformer. For example, for a lighting Tr1.6.6k / 210-105V single-phase 200kVA transformer, the thermal relay current value of the thermal relay on the secondary side of the ammeter CT is 3.9A, and the load factor for alarm generation is 73%, or 0.73.

[0172] For example, for a single-phase lamp, (1) the capacity of Tr1 is 6.6k / 210-105V single-phase 200kVA transformer is 200kVA, (2) the maximum allowable current is (200kVA / 210V x 1.0) x 1000 = 952.4A, and the ammeter CT1000A is (3) the thermal relay current value is 3.9A, (4) the alarm load current for TR overcurrent prevention is 780A, (5) proportionally the equipment capacity of TR safety protection is 164KW, and (6) the load factor is 82%.

[0173] The safety functions of conventional transformers are as follows: for example, the TR has a capacity of 200 kVA, a maximum current value of 952 A, and a design of a secondary output of 5 A. For example, the alarm current value of 3.9 A is also set by a thermal relay, and the alarm load current is 780 A. At a load factor of 82% (780 A), an alarm buzzer will sound at the site of the power receiving and transforming equipment.

[0174] In the DESCON safety control system, for example, the No. 1 light transformer has (1) a capacity of 200 KVA, (2) a maximum current of 952 A, (3) a thermal relay of 3.9 A, (4) an alarm load current of 780 A, (5) a load equipment capacity of 164 KW, and (6) a load factor of 82%. (7) The current of the No. 1 light, which is arbitrarily set in advance, of 780 A, is designed and constructed as the alarm load current. (8) For example, the alarm load current of 780 A and the load factor of 82% are arbitrarily set in advance. Furthermore, assuming a safety factor of 0.95, (9) the caution current = (780AX0.95) = 741.0 A, and (10) the current load rate = (741.0 / 952.0) = 77.8%. If a detection current of 741.0 A is detected, (10) an alert can be sent to the relevant person via their PC, tablet, voice, image, email, etc., along with the name of the building or facility, location, name of the relevant switchboard or distribution board, etc., stating that the caution current is 741 A and the current load rate is 77.8%.

[0175] In the DESCON safety control system, for example, the No. 1 light transformer has (1) a capacity of 200 KVA, (2) a maximum current of 952 A, (3) a thermal relay of 3.9 A, (4) an alarm load current of 780 A, (5) a load equipment capacity of 164 KW, and (6) a load factor of 82%. (7) The current of the No. 1 light, which is arbitrarily set in advance, of 780 A, is designed and constructed as the alarm load current. (8) For example, the alarm load current of 780 A and the load factor of 82% are arbitrarily set in advance. Furthermore, assuming a safety factor of 0.95, (9) the caution current = (780AX0.95) = 741.0 A, and (10) the current load rate = (741.0 / 952.0) = 77.8%. If a detection current of 741.0 A is detected, (10) an alert can be sent to the relevant person via their PC, tablet, voice, image, email, etc., along with the name of the building or facility, location, name of the relevant switchboard or distribution board, etc., stating that the caution current is 741 A and the current load rate is 77.8%.

[0176] In the DESCON safety control system, for example, the No. 1 power transformer has (1) a capacity of 500 KVA, (2) a maximum current of 1718 A, (3) a thermal relay of 4.5 A, (4) an alarm load current of 1350 A, (5) a load equipment capacity of 393 KW, and (6) a load factor of 79%. (7) The No. 1 power transformer current of 1350 A, which is arbitrarily determined in advance, is designed and constructed as the alarm load current. (8) For example, the safety control system is designed and constructed as an arbitrary predetermined value of the alarm load current of 1350 A and the load factor of 79%. Multiplying by the total coefficient of 0.95, (9) safe current = (1350AX0.95) = 1282.5 A, and (10) safe load factor = (1282.5 / 1718.0) = 74.7%. If a detection current of 1282.5 A is detected, (10) an alert can be sent to the relevant person's PC, tablet, voice, image, email, etc., along with information such as the name of the building or facility, location, and name of the relevant switchboard or distribution board, stating that the caution current is 1282.5 A and the current load factor is 74.7%.

[0177] In the DESCON safety control system, for example, the No. 1 power transformer has (1) a capacity of 500 kVA, (2) a maximum current of 1,718 A, (3) a thermal relay of 4.5 A, (4) an alarm load current of 1,350 A, (5) a load equipment capacity of 393 kW, and (6) a load factor of 79%. (7) The No. 1 power transformer is designed and constructed with a predetermined alarm load current of 1,350 A. (8) For example, when the predetermined alarm load current exceeds 1,350 A and the load factor exceeds 79%, for example, the detection current is 1,430 A, and the load factor = (detection current 1,450 A / maximum current 1,718 A) = 84.4%. (9) When a detected current of 1450A exceeds a preset arbitrary 1350A, (detected current 1450A - set current 1350A) = 100A is automatically cut off in the relevant No. 1 power distribution board, for example, 100A in circuit No. 6 of distribution board No. 1, which has a preset cutoff circuit, thereby reducing the detected current to 1350A. (10) An alert can be sent to the relevant person's PC, tablet, voice, image, email, etc., along with, for example, the name of the building or facility, location, name of the relevant distribution board or distribution board, etc., and that the alarm current is 1450A, the current load rate is 84.4%, and the alarm has been cut off.

[0178] Notwithstanding the above, the DESCON Safety Control System determines whether the (1) maximum allowable temperature of the insulation type of lighting and power transformers is 105°C for type A, 120°C for type E, 130°C for type B, 155°C for type F, and 180°C for type H, and whether the (2) detected temperature of the temperature sensor installed in the TR is above the corresponding maximum allowable temperature or below the maximum allowable temperature, or whether the (3) maximum allowable temperature value of each of the above types A to H is below the corresponding maximum allowable temperature. For example, (4) a safety temperature coefficient of 0.97 is arbitrarily set in advance as the safety caution temperature. For example, (5) the TR of Class A is = (Class A maximum allowable temperature 105°C x 0.97) = caution temperature 102°C. (6) When a caution temperature is detected, an alert can be sent to the PC, tablet, smartphone, etc. of the relevant person, along with, for example, the relevant customer name, building / facility name, location, relevant light, power transformer name, etc., along with "Caution temperature 102.0°C," "Caution temperature rate 97.0%, etc."

[0179] In addition, the system terminal's electrical equipment load equipment name, etc. is sent as an alert in the form of voice, numerical values, images, etc., and the alert ringtone is sent continuously until the relevant person confirms and resets, preventing the relevant person from missing the confirmation. (7) If the detected temperature exceeds the "maximum allowable temperature 105°C", for example, 132°C, (8) the alarm cutoff temperature coefficient, which is set in advance, is, for example, 1.10, so that the alarm cutoff temperature = (maximum allowable temperature 105°C x alarm cutoff temperature coefficient 1.10) = 112.2, and (9) the automatic cutoff temperature = (detected temperature 132°C - alarm cutoff temperature 11 (10) Automatic tripping rate = 1 - (alarm tripping temperature 112.2℃ / detection temperature 132℃) = 15% of the temperature (10) until the temperature drops to 15%, i.e., (10) automatic tripping rate = 1 - (alarm tripping temperature 112.2℃ / detection temperature 132℃) = 19.8℃, the (11) tripping order of the relevant distribution board, distribution board circuits, terminal load equipment, electrical equipment, etc., which can be arbitrarily set in advance and which can be tripped without causing any problems, is determined, and the electrical equipment, etc. is automatically tripped, so that the (12) current value passing through the relevant TR is reduced, and the TR temperature (13) can be reduced in proportion to the current value due to the reduction in the thermal load of the electrical resistance.

[0180] The DESCON Safety Control System next states that the boiling point of insulating oil for insulation type A is approximately 290℃ to 340℃, but for example, if the temperature of an insulation type A transformer, for example, the boiling point of insulating oil is 290℃ and the safety factor is set arbitrarily in advance, for example, to 0.6, then when it detects an insulation temperature of (290℃ x 0.5) = 145℃, it will automatically shut off the circuits of the electrical equipment and load equipment systems in each distribution board of the system of the distribution board of the relevant transformer, for example, in the order of the circuit breakers of the distribution board, using an arbitrarily set program in advance, and will continue to shut off sequentially until the temperature drops to the maximum allowable temperature of 105℃, and when the boiling point alarm temperature is reached, it will send an alert to the relevant person via their PC, tablet, voice, image, email, etc., with details of the automatic shutdown of the relevant equipment, including the customer name, building facilities, transformer distribution board, system distribution board, electrical equipment, load equipment, etc.

[0181] In the DESCON safety control system, for example, the No. 1 light transformer has (1) a capacity of 200 KVA, (2) a maximum current of 952 A, (3) a thermal relay of 3.9 A, (4) an alarm load current of 780 A, (5) a load equipment capacity of 164 KW, and (6) a load factor of 82%. (7) The current of the No. 1 light, which is arbitrarily determined in advance, of 780 A is designed and constructed as the alarm load current. (8) For example, the alarm load current of 780 A and the load factor of 82% are predetermined. With an arbitrarily set safety factor of 0.95, (9) the caution current = (780AX0.95) = 741.0 A, and (10) the current load rate = (741.0 / 952.0) = 77.8%. If a detection current of 741.0 A is detected, (10) an alert will be sent to the relevant person via their PC, tablet, voice, image, email, etc., along with information such as the name of the building or facility, location, and name of the relevant switchboard or distribution board, along with an alert that the caution current is 741 A and the current load rate is 77.8%.

[0182] In the DESCON safety control system, for example, the No. 1 light transformer has (1) a capacity of 200 kVA, (2) a maximum current of 952 A, (3) a thermal relay of 3.9 A, (4) an alarm load current of 780 A, (5) a load equipment capacity of 164 kW, and (6) a load factor of 82%. (7) The No. 1 light current of 780 A, which is arbitrarily set in advance, is designed and constructed as the alarm load current. (8) For example, if the alarm load current exceeds the arbitrarily set alarm load current of 780 A and the load factor exceeds 82%, for example, the detection current is 801 A, and the load factor = (detection current 800 A / maximum current 952 A) = 84.0%. (9) When a detected current of 800A exceeds a preset arbitrary 780A, (detected current 800A - set current 780A) = 20A is automatically cut off at the relevant No. 1 electric light distribution panel, for example, 20A at circuit No. 6 of distribution panel No. 1 for which a cutoff circuit has been set in advance, thereby reducing the detected current to 780A. (10) An alert can be sent to the relevant person's PC, tablet, voice, image, email, etc., along with, for example, the name of the building or facility, location, name of the relevant distribution panel or distribution panel, etc., and that the alarm current is 801A, the current load rate is 84.0%, and the alarm has been cut off.

[0183] In the DESCON safety control system, for example, the No. 1 power transformer has (1) a capacity of 500 KVA, (2) a maximum current of 1718 A, (3) a thermal relay of 4.5 A, (4) an alarm load current of 1350 A, (5) a load equipment capacity of 393 KW, and (6) a load factor of 79%. (7) The No. 1 power transformer current of 1350 A, which is arbitrarily determined in advance, is designed and constructed as the alarm load current. (8) For example, the safety control system is designed and constructed as an arbitrary predetermined value of the alarm load current of 1350 A and the load factor of 79%. Multiplying by the total coefficient of 0.95, (9) safe current = (1350AX0.95) = 1282.5 A, and (10) safe load factor = (1282.5 / 1718.0) = 74.7%. If a detection current of 1282.5 A is detected, (10) an alert can be sent to the relevant person's PC, tablet, voice, image, email, etc., along with information such as the name of the building or facility, location, and name of the relevant switchboard or distribution board, stating that the caution current is 1282.5 A and the current load factor is 74.7%.

[0184] Notwithstanding the above, the DESCON safety control system, for example, for electric lighting and power transformers, (1) the allowable maximum temperature for each insulation type is 105°C for type A, 120°C for type E, 130°C for type B, 155°C for type F, and 180°C for type H. The allowable maximum temperature for the corresponding type A to H is used as the standard. (2) The temperature sensor installed in the TR detects the temperature exceeding the allowable maximum temperature. For example, (5) the TR for type A = (A type allowable maximum temperature 105°C x 0.97) = Caution temperature 102°C, "Caution temperature 102.0°C." The alarm cutoff coefficient temperature, which is set in advance, is, for example, 1.0, 105°C. Alternatively, if the preset alarm temperature cutoff coefficient is 1.10, and (7) the detected temperature is, for example, 132°C, then the alarm temperature cutoff temperature = (Class A allowable maximum temperature 105°C x optional setting coefficient 1.10) = 112.2°C, and (8) the automatic cutoff temperature = (detected temperature 132°C - alarm cutoff temperature 112.2°C) = 19.8°C, the allowable maximum temperature is 105°C, or (9) the automatic cutoff rate = 1 - (alarm cutoff temperature 112.2°C / detected temperature 132°C) = 15%. The (11) cutoff order of the circuits of the relevant distribution board, distribution board, etc., and terminal load equipment, electrical equipment, etc., which are preset arbitrarily and can be cut off without causing any problems, is determined. By automatically shutting off electrical appliances, etc., the TR temperature decreases in proportion to the current value due to the reduction in the thermal load of the electrical resistance, (13) and the TR temperature decreases. (1) When the DESCON safety control system detects the detection temperature of 132°C, the alarm temperature rise rate = (detection temperature 132°C / maximum allowable temperature 105°C) = 121%, and an alert can be sent to the PC, tablet, smartphone, etc. of the relevant person, including, for example, the relevant customer name, building / facility name, location, relevant light, power transformer name, etc., along with the alarm temperature of 132°C and the alarm temperature rise rate of 121.0%.

[0185] In the DESCON safety control system, for example, the No. 1 light transformer has (1) a capacity of 200 kVA, (2) a maximum current of 952 A, (3) a thermal relay of 3.9 A, (4) an alarm load current of 780 A, (5) a load equipment capacity of 164 kW, and (6) a load factor of 82%. (7) The No. 1 light current of 780 A, which is arbitrarily set in advance, is designed and constructed as the alarm load current. (8) For example, if the alarm load current exceeds the arbitrarily set alarm load current of 780 A and the load factor exceeds 82%, for example, the detection current is 801 A, and the load factor = (detection current 800 A / maximum current 952 A) = 84.0%. (9) When a detected current of 800A exceeds a preset arbitrary 780A, (detected current 800A - set current 780A) = 20A is automatically cut off at the relevant No. 1 electric light distribution panel, for example, 20A at circuit No. 6 of distribution panel No. 1 for which a cutoff circuit has been set in advance, thereby reducing the detected current to 780A. (10) An alert can be sent to the relevant person's PC, tablet, voice, image, email, etc., along with, for example, the name of the building or facility, location, name of the relevant distribution panel or distribution panel, etc., and that the alarm current is 801A, the current load rate is 84.0%, and the alarm has been cut off.

[0186] In the DESCON safety control system, for example, the No. 1 power transformer has (1) a capacity of 500 kVA, (2) a maximum current of 1,718 A, (3) a thermal relay of 4.5 A, (4) an alarm load current of 1,350 A, (5) a load equipment capacity of 393 kW, and (6) a load factor of 79%. (7) The No. 1 power transformer is designed and constructed with a predetermined alarm load current of 1,350 A. (8) For example, when the predetermined alarm load current exceeds 1,350 A and the load factor exceeds 79%, for example, the detection current is 1,430 A, and the load factor = (detection current 1,450 A / maximum current 1,718 A) = 84.4%. (9) When a detected current of 1450A exceeds a preset arbitrary 1350A, (detected current 1450A - set current 1350A) = 100A is automatically cut off in the relevant No. 1 power distribution board, for example, 100A in circuit No. 6 of distribution board No. 1, which has a preset cutoff circuit, thereby reducing the detected current to 1350A. (10) An alert can be sent to the relevant person's PC, tablet, voice, image, email, etc., along with, for example, the name of the building or facility, location, name of the relevant distribution board or distribution board, etc., and that the alarm current is 1450A, the current load rate is 84.4%, and the alarm has been cut off.

[0187] The DESCON safety control system is a system in which the high voltage of, for example, an electric power company's 6600V is reduced to, for example, 100V for lighting and 200C for power by, for example, the No. 1 to No. 5 electric lighting lances and No. 1 to No. 5 power transformers in the receiving and transforming equipment, and is configured to, for example, No. 1 to No. 5 electric lighting distribution boards and No. 1 to No. 5 power distribution boards connected by each main line, and the electric lighting and power distribution boards are connected to the system main line, and the power distribution boards are connected to the branch main line, and each electrical equipment, mechanical equipment, control equipment, electrical equipment, load equipment, etc. consumes power and operates.

[0188] The DESCON Safety Control System is based on the (1) maximum allowable temperatures for insulation types of major electrical equipment in substation facilities, such as electric lighting trusses and power transformers, which are 105°C for Type A, 120°C for Type E, 130°C for Type B, 155°C for Type F, and 180°C for Type H. Temperature sensors installed on the electric lighting trusses and power transformers detect the temperature of the transformer in question. For example, the maximum allowable temperature for Type A is 105°C. For example, a warning temperature can be set in advance. For Type A, the TR is = (Type A maximum allowable temperature 105°C x 0.97) = warning temperature 102°C, or 105°C, which is the maximum allowable temperature of 1.0. If the detected temperature of the transformer in question reaches this value, an alert will be sent to the relevant person's PC, tablet, or via voice, image, email, etc., along with information such as the name of the building or facility, location, name of the relevant electric lighting or power transformer, along with an alert that the temperature rise rate of the warning temperature of 102°C is 97% or that the temperature rise rate of 105°C is 100%.

[0189] If the preset alarm cutoff coefficient temperature is, for example, 1.0, which is 105°C, or if the preset alarm temperature cutoff coefficient is 1.10, and the (7) detected temperature is, for example, 132°C, then the alarm temperature cutoff temperature = (Class A maximum allowable temperature 105°C x preset coefficient 1.10) = 112.2°C, and (1) automatic cutoff temperature = (detected temperature 132°C - alarm cutoff temperature 112.2°C) = 19.8°C, (9) automatic cutoff rate = 1 - (alarm cutoff temperature 112.2°C / detected temperature 132°C) = 15%, the (11) cutoff order of the circuits of the relevant distribution boards and distribution boards, terminal load equipment, electrical equipment, etc., which have been preset and can be cut off without causing any problems, is determined, and by automatically cutting off the electrical equipment, etc., the TR temperature (13) decreases in proportion to the current value due to the reduction in the thermal load of the electrical resistance, and the TR temperature (13) decreases.

[0190] When the DESCON Safety Control System detects the detection temperature of 132°C, it issues an alarm with an alarm temperature rise rate of 121% (detection temperature 132°C / maximum allowable temperature 105°C), and can send an alert to the PC, tablet, smartphone, etc. of the relevant person, including, for example, the customer name, building / facility name, location, relevant light, power transformer name, etc., along with the alarm temperature of 132°C and the alarm temperature rise rate of 121.0%.

[0191] The DESCON Safety Control System is capable of sending alerts to relevant parties via PC, tablet, voice, image, email, etc., including the name of the building or facility, location, name of the relevant light or power transformer, etc., as well as voice, image, email, etc., if the temperature detected by a temperature sensor installed on the light or power high-voltage transformer for the main electrical equipment of the electrical equipment of the low-voltage switchboard equipment for the light and power system falls under, for example, 9, 9-1, (1) above.

[0192] Notwithstanding the above, if the current detected by the current measuring device CT of the low voltage switchboard for lighting and power in the high voltage transformer system for the main electrical equipment of the electrical equipment of the lighting and power system low voltage switchboard equipment of the power receiving and transforming equipment, (1) falls under the conditions of 7, 7-1, etc., the DESCON safety control system can be configured to send an alert to the relevant person via PC, tablet, voice, image, email, etc., with information such as the name of the building or facility, location, name of the relevant lighting and power transformer, etc., as well as voice, image, etc.

[0193] Notwithstanding the above, if the current detected by the current measuring device CT of the electric light / power low voltage switchboard of the electric light / power high voltage transformer system of the main electrical equipment of the electrical equipment of the electric equipment of the receiving and transforming equipment, the electric light of the power high voltage transformer system, and the low voltage distribution board of the power system, falls under, for example, 7, 7-1, etc., the DESCON safety control system can be configured to send an alert to the relevant person's PC, tablet, voice, image, email, etc., with, for example, the name of the building / facility, location, name of the relevant electric light, power transformer, etc., as well as an alert by voice, image, etc.

[0194] Notwithstanding the above, the DESCON Safety Control System (1) when the temperature of a high-voltage transformer for lighting or power in a power receiving and transforming facility reaches a certain value due to, for example, high outside or ambient temperatures or high current load on a low-voltage distribution panel in the system of the corresponding transformer, the corresponding transformer will be automatically shut off as described in 10 above, and an alert will be sent to the relevant person via PC, tablet, voice, image, email, etc., with, for example, the name of the building or facility, the location, the name of the corresponding lighting or power transformer, etc., or (2) when high operation of a distribution board, electrical equipment, load equipment, electrical equipment, electrical equipment, mechanical equipment, control equipment, electrical equipment, etc. in the low-voltage distribution panel equipment system causes the current in the corresponding lighting or power distribution panel to be automatically shut off as described in 11 above, and an alert will be sent to the relevant person via PC, tablet, voice, image, email, etc. with, for example, the name of the building or facility, the location, the name of the corresponding lighting or power transformer, etc., with, for example, the name of the building or facility, the location, the name of the corresponding lighting or power transformer, etc.,

[0195] Notwithstanding the above, the DESCON Safety Control System (1) if the temperature of a high-voltage transformer for lighting or power in a power receiving and transforming facility rises due to, for example, high outside or ambient temperatures or high current loads in the low-voltage distribution panel of the system of the transformer in question, the DESCON Safety Control System will automatically shut off the transformer in question as described in 10 above, and will send an alert to the relevant person via PC, tablet, voice, image, email, etc., with, for example, the name of the building or facility, its location, the name of the lighting or power transformer in question, or (2) if the current rises due to high operation of the distribution board, electrical equipment, load equipment, electrical equipment, electrical equipment, mechanical equipment, control equipment, electrical equipment, etc. in the low-voltage distribution panel equipment system, the DESCON Safety Control System will automatically shut off the current in the lighting or power distribution panel in question as described in 11 above, and will send an alert to the relevant person via PC, tablet, voice, image, email, etc., with, for example, the name of the building or facility, its location, the name of the lighting or power transformer in question,

[0196] Regardless of the above, the DESCON Safety Control System (1) controls and alerts the relevant transformers in the system as described in 10 above when the temperature of the high-voltage transformers for lighting and power in the power receiving and transforming equipment rises before the current in the low-voltage distribution panel. Also, (2) the current and operation rate of the relevant distribution panel can be sent to the relevant person's PC, tablet, voice, image, email, etc., so that the relevant person can be aware of the temperature status of the relevant transformer and the current and operation status of the low-voltage distribution panel in the system.

[0197] Furthermore, regardless of the above, the DESCON safety control system (1) controls and alerts the relevant transformers in the system as described in 11 above, when the current and operation rate of the electric lighting and power distribution panels rise before the temperature of the high-voltage transformers for the electric lighting and power in the power receiving and transforming equipment. Also, (2) the current and operation rate of the relevant distribution panels can be sent to the relevant parties via PC, tablet, audio image, email, etc., so that the relevant parties can be aware of the temperature status of the relevant transformers and the current and operation status of the low-voltage distribution panels in the system.

[0198] As mentioned above for building facilities, the economy and industry are expanding on a global scale, information technology is evolving in real time, becoming borderless, and human interaction is increasing. Along with the expansion of information, along with PCs, tablets, and smartphones, the quality and quantity of logistics is increasing in Japan and around the world. For example, the quality and size of logistics centers in II-1. building facilities has grown dramatically, and with the advent of cloud computing, data centers, material handling systems, semiconductor factories, inbound event halls, hotels, terminal buildings, skyscrapers, hotels, etc., people's activities are becoming 24-hour, labor is being concentrated, convenience is being provided by robots, and the various features of outdoor facilities are appealing to various functions. In terms of lifestyle, with the aging population, declining birthrate, single-person households, and the rise of super-high-rise apartment buildings, the number of items that utilize electricity, the number of equipment, machinery, electrical equipment, home appliances, etc., has increased dramatically, 365 days a year, 24 hours a day, and convenience is increasing.

[0199] On the other hand, the number of various electrical accidents is proportional to this. For example, the electricity consumed by buildings and facilities has increased dramatically and is no longer shut down for 24 hours. In particular, electricity is supplied by the power company to the substation equipment, which includes high-voltage transformers for lighting and power, low-voltage distribution panels for lighting and power in the system, main lines and system distribution panels, main lines, electrical equipment, machinery, terminal load equipment, etc.

[0200] Electrical equipment is used in a wide variety of applications, including logistics centers, factories, offices, hotels, terminal buildings, apartment complexes, commercial facilities, and assembly halls in buildings and facilities, as well as for various production equipment, electrical equipment, picking, solar power generation, wind power generation, batteries, storage batteries, data centers, computers, power plants, substations, cars, ships, airplanes, trains, and outdoor facilities.Various types of electrical equipment and facilities are being manufactured, and the number of electrical equipment, main lines, panels, control panels, circuits, and connecting fixtures is increasing proportionally.Various measures are being taken to deal with leakage currents and leakage currents generated by each electrical equipment and facility, but it is believed that the current situation is such that, for example, deterioration over time, burning of equipment, and poor insulation of the panels, main lines, circuits, wiring, connecting fittings, and terminal load equipment of the electrical equipment can lead to electrical shock, leakage currents, stray currents, etc., which can be factors in electrical equipment burning and fire accidents.

[0201] As mentioned above, safety inspections are conducted in accordance with relevant laws and regulations, such as monthly safety inspections of electrical equipment, and annual comprehensive inspections in which power is cut off to measure insulation, torque tests, and measurements of current and voltage, etc., and are reported in accordance with relevant laws and regulations. However, the current situation is that the occurrence of leakage current, stray current, etc. in systems such as building facilities, outdoor facilities, various electrical equipment, main lines, panels, control panels, circuits, connecting devices, various equipment and machinery by main lines, mechanical equipment, terminal load equipment, process equipment, various plants, etc., and the current state of occurrence of such current in the relevant electrical equipment, terminal load equipment, main lines, wiring, etc., is not yet fully understood in reality.

[0202] The DESCON Safety Control System is used in buildings and outdoor facilities, such as high voltage transformers for lighting and power in substation equipment, and low voltage distribution panels, distribution panels, control panels, electrical equipment, machinery, terminal load equipment, etc. for lighting and power in the system. The following applies: 1. Current and voltage of the earth leakage circuit breaker, 2. Type and sensitivity current, 3. Rated sensitivity current, etc. The earth leakage detectors such as ZCTs installed in the main equipment of the above-mentioned panels, and in each circuit of each panel of the above-mentioned equipment, and in the control panels of each equipment, etc., are installed in each panel and each circuit unit. They detect leakage currents, and (1) are available in advance, such as rated sensitivity currents of 5mA, 10mA, 15mA, and 30mA for the high-speed type (2), 50mA, 100mA, 200mA, 300mA, 500mA, and 1000mA for the medium-sensitivity type, and 3A, 5A, 10A, and 20A for the low-sensitivity type. (2) The sensitivity classification is selected based on the main application; for example, high-sensitivity is used in places with a high risk of electric shock, such as in wet places, to protect against electric shock caused by contact with live wires, and for mobile or portable equipment where grounding is not reliable. (3) Medium-sensitivity is used in circuits where the equipment is reliably grounded or in large-capacity circuits where high-sensitivity types would cause malfunctions. (4) Low-sensitivity types are available in 3A, 5A, 10A, and 20A, and are used where medium-sensitivity types would cause malfunctions.

[0203] As mentioned above, the DESCON safety control system has the function of detecting and cutting off rated sensitivity currents of 5mA, 10mA, 15mA, and 30mA for high-speed systems, such as lighting and power distribution boards, distribution boards, control panels, electrical equipment, mechanical equipment, and terminal load equipment, etc. (1) For example, the type and sensitivity current are classified according to the operation limit, and the coefficient of the caution leakage current is set to 0.8, which is a preset arbitrary value between 5mA and 30mA, for example, 5.0mA = (5.0mA AX coefficient 0.8) = 4.0mA, 10.0mA = (10.0mA AX coefficient 0.8) = 4.0mA, The following leakage currents are detected by leakage detectors such as ZCTs installed on each of the above-mentioned panels and equipment, and an alert can be sent via the PC, tablet, voice, image, email, etc. of the relevant parties, including the name of the building or facility, location, name of the relevant switchboard or distribution board, name of the electrical equipment, mechanical equipment, load equipment, etc., along with a warning leakage current of, for example, 4.0mA to 24.0mA, with a leakage current coefficient of 80%.

[0204] The DESCON safety control system is suitable for, for example, lighting and power distribution boards, distribution boards, control panels, electrical equipment, mechanical equipment, terminal load equipment, etc. (1) For example, the type and sensitivity current are classified by operation limit, and the rated sensitivity current of high sensitivity type and high speed type is 5mA, 10mA, 15mA, 30mA, etc., and has a function to detect and warn, and can be set arbitrarily in advance, for example, from 5mA to 30mA. If the caution leakage current coefficient is set to 0.8, for example, 5.0mA = (5.0mA AX coefficient 0.8) = 4.0mA, 10.0mA = (10.0mA AX coefficient 0.8) = 8.0mA, 15.0mA = (15.0mA AX coefficient 0.8) = 12.0mA, 30.0mA = (30mA AX 0.8) = 24.0mA will be detected by leakage detectors such as ZCTs installed on each of the above-mentioned panels and equipment, and an alert will be sent via PC, tablet, voice, image, email, etc. to the relevant parties, including the name of the building or facility, location, name of the relevant switchboard or distribution board, name of the electrical equipment, mechanical equipment, load equipment, etc., along with a caution leakage current of, for example, 4.0mA to 24.0mA, with a leakage current coefficient of 0.8.

[0205] Note: When the leakage current coefficient reaches the leakage current value set for the rated sensitivity current, for example, and the earth leakage breaker operates and cuts off the relevant switchboard / distribution board, electrical equipment, machinery equipment, load equipment, etc., there is a loss of time when the power supply to the above-mentioned related equipment in the relevant building or outdoor facility stops operating, and it is unclear whether the leakage current is within the allowable range for each panel of the system's electrical equipment, control equipment, machinery equipment, electrical equipment, terminal load equipment, etc., or whether it is an abnormal leakage current, so it has traditionally been thought that productivity and safety are not necessarily perfect.

[0206] The leakage current coefficient depends on the characteristics and functional usage of the relevant building / outdoor facility, such as production data centers, factories, large logistics facilities, etc., large commercial facilities that accommodate an unspecified number of people, high-rise buildings, terminal buildings, hotels, offices, apartment buildings, etc., and homes and apartment buildings that prioritize safety and comfort, but the leakage current coefficient specified as the leakage current coefficient may be any predetermined value, for example, 0.8 to 0.9.

[0207] As mentioned above, the DESCON safety control system is used in, for example, lighting and power distribution boards, distribution boards, control panels, electrical equipment, mechanical equipment, terminal load equipment, etc. (1) For example, the rated sensitivity current of the high-speed type mentioned above is 5mA, 10mA, 15mA, 30mA, etc., and it has the function of detecting and cutting off. For example, the coefficient of the caution leakage current, which can be set arbitrarily in advance from 5mA to 30mA, is set to 0.8, for example, 5.0mA = (5.0mA AX coefficient 0.8) = 4.0mA, 10.0mA = (10.0mA AX coefficient 0.8). 8) = 8.0mA, 15.0mA = (15.0mAX coefficient 0.8) = 12.0mA, 30.0mA = (30mAX 0.8) = 24.0mA are detected by the earth leakage breakers installed on each of the above-mentioned panels, facilities, etc., and an alert can be sent via the PC, tablet, voice, image, email, etc. of the relevant person, with information such as the building / facility name, location, name of the relevant switchboard / distribution board, name of electrical equipment, machinery equipment, load equipment, etc., along with a warning leakage current of, for example, 4.0mA to 24.0mA, with a leakage current coefficient of 80%.

[0222] <An example of a configuration and wiring diagram for the high-voltage transformer for electric lighting and power in the power receiving and transforming equipment, the low-voltage distribution panel for electric lighting and power, the electric lighting and power distribution panel for the system, the electric lighting and power circuits, and the electric lighting and power electrical equipment, mechanical equipment, terminal load equipment, etc. in the system> and <An example of the configuration of the DESCON safety control system related to the electric lighting distribution panel and the power distribution panel> When the current detected by the CT of an alarm current alarm type electric light TR rises above the caution alarm current of 780A, and the alarm cutoff coefficient for the caution alarm current of 780A is set to 1.10, the automatic cutoff current = (1350AX1.10) = 1485A or more is automatically cut off. The program is as follows:

[0223] Or, for the caution current safety type, (1) the lamp TR1 capacity is 200KVA, (2) the maximum current is 952A, the (3) alarm load current for overload prevention is 780A, and proportionally (4) the TR load equipment capacity is 164KW are entered as a database, and for example, a CT ammeter installed in the lamp TR detects that the detected current is an overcurrent for safety protection, (5) an alarm current exceedance is detected by the CT detection, (6) the alarm load current is 780A, but due to the arbitrarily preset (7) caution current coefficient of 0.97, (8) caution alarm current = (alarm load current 780 AX caution current coefficient 0.97) = 756A, the safety is high, the load rate of the relevant TR decreases, and an alert is sent to the relevant person's PC, tablet, smartphone, etc. with voice, numerical values, images, etc. to notify the relevant person of the relevant information, for example, customer name, building name, facility name, location, lamp, type of power, capacity, electrical equipment at the system terminal, load equipment name, etc. The alert ringtone can be continuously transmitted until the person concerned confirms and resets the setting, thereby preventing the person concerned from failing to confirm the setting.

[0224] In addition, the DESCON safety control system automatically shuts off the detected current when it increases and the maximum current is 952 A, which is set arbitrarily in advance, (9) for example, the maximum current coefficient is 0.9, (10) the surplus rate is 10%, and (11) the alarm shutoff current = (maximum current 952 AX maximum current coefficient 0.9) = 857 A or more. If the detected current is (12) 938A, then (13) automatic shutdown current = (detection current 938A) - (alarm shutdown current 857A) = 81A will be automatically shut off, and (14) converted to equipment automatic shutdown capacity KVA = ((current 81A x voltage 210V x power factor 1.0) / 1000A = 17KVA, and the automatic shutdown equipment capacity is 17KVA, then (15) automatic shutdown rate 8.6% will be automatically shut off, and the order of shutting off the terminal load equipment, electrical equipment, etc. of the relevant main distribution board and additional distribution board will be determined, and the terminal load equipment, electrical equipment, etc., that can be shut off without causing any problems, as well as the relevant boards, circuits, etc. will be automatically shut off.

[0225] The DESCON safety control system sends alerts of the above-mentioned automatic shutoff to the relevant parties' PCs, tablets, smartphones, etc., including the customer name, building name, low-voltage distribution board, distribution board, control panel, circuit, etc., as well as audio, images, temperature values, etc. to terminal electrical equipment, terminal load equipment, etc., and continues to send these alerts until the relevant parties confirm that the alert has been sent.The system can be configured to provide a means for the relevant parties to check safety in real time after the relevant automatic shutoff and to take subsequent action.

[0226] The DESCON Safety Control System (1) automatically shuts off various types of equipment and electrical devices, such as those used in logistics centers, large freezers, refrigerators, and other products and manufacturing facilities where many people gather, terminal buildings, hotels, and other similar facilities, as well as data centers for important data, research and test results, infrastructure substations, and transportation trains and ships, etc., using computer programs such as AI and IoT. (2) When the terminal equipment and electrical devices are automatically shut off by a predetermined program, the terminal equipment and electrical devices are automatically shut off by a predetermined program. (3) When the terminal equipment and electrical devices are automatically shut off by a predetermined program, the terminal equipment and electrical devices are automatically shut off by a predetermined program. The DESCON safety control system, which is composed of remote devices for each system, such as control panels, main lines, circuits, breakers, etc., as well as cloud servers, LANs, etc., uses an emergency response protection program via remote devices for each system, cloud servers, LANs, etc. (4) The remote devices, such as the relevant distribution boards, distribution boards, control panels, etc., send a signal to the protection stop device, and the control equipment, etc., as a whole or selected terminal equipment, etc., is safely protected, and has the function of shutting down by program, and can be configured to have a means for controlling the stop function normally and safely, and a means for confirming the stop signal.

[0227] When the current detected by the CT of a caution current safety type electric light TR rises above the caution alarm current of 756A and reaches a preset maximum current of 952A with a maximum current coefficient of 0.9, the automatic cutoff current = (maximum current 952AX0.9) = 857A or more is automatically cut off.The program is as follows:

[0228] The configuration and functions of the following substation equipment (hereinafter referred to as cubicles) according to the DESCON safety system: A. Lighting and power transformers, B. Lighting and power low-voltage distribution boards, C. Distribution boards and terminal load equipment.

[0229] For example, the building's power receiving and transforming equipment has three lighting transformers (hereinafter referred to as TR) and four power transformers (hereinafter referred to as TR), and the TR is of type A with capacity, thermal relay (thermal relay), circuit current, equipment capacity, etc. The main distribution board + expansion distribution board configuration, the k. program caution coefficient and caution current of the system, automatic shutdown of k1 to K6 and automatic shutdown distribution board, and circuit are as follows:

[0230] The capacities of the power transformers NO1 to NO4, d. maximum load current, f. thermal relay alarm setting value, g. load current value, i. maximum load factor of the system, and k. safe allowable current are as follows:

[0231] (1) The overcurrent protection thermal relay of transformer Tr1. 3φ500kVA on power panel No. 1 of the low-voltage distribution panel mentioned above has a 1500 / 5A CT of the relevant circuit installed on the secondary side, and an external alarm output is set at, for example, 4.5A.

[0232] (1) Alarm load current value = (4.5A × 1500) / 5A = 1350A, (2) h. load equipment capacity h1 = (√3 × hXbXe) / 1000 = (1.732 × 1350A × 210V × 0.8) ÷ 1,000 = 393kW, (3) Load factor = (393kW / 500KVA) = 79%.

[0233] The safety features of conventional transformers include, for example, c. TR capacity 500kVA, d. maximum current value 1718A, e. secondary side output 5A design, f. alarm current value 4.5A also by thermal relay, g. alarm load current 1350A, j. load factor 79%, 1323A, alarm buzzer sounding at the site of the power receiving and transforming equipment, etc.

[0234] For example, in the case of a main distribution board with (1) an alarm current of 1350A, (2) a load equipment capacity of 393kW, and (3) a load utilization rate of 79%, (4) in order to enhance the safety function of the transformer, the DESCON safety control system detects a preset alarm current of 1350A or a warning coefficient of 0.98, for example (5) (alarm current 1350AX warning coefficient 0.98) = 1323A as a warning current, and sends an alert to the relevant person's PC, tablet, smartphone, etc. with the relevant information, such as the customer name, building name, facility name, location, and transformer name, and continues to send alerts with voice, numerical values, images, etc. for each system until the relevant person confirms and resets the alert.

[0235] For example, in a building facility, outdoor facility, or other power receiving and transforming equipment, for example, the power TR capacity is 500kVA, the maximum current is 1718A, and the low-voltage power distribution panel of the power receiving and transforming equipment has a safety protection function, for example, a thermal relay of 3.9A and an alarm load current of 1350A for a guard setting value of 5.0A. The load equipment capacity is 393KW and the load rate is 79%. (1) The capacity of the TR No. 1 in 4-1 below is 500KVA. In comparison with the capacity of the low-voltage power distribution panel of 500KVA, the capacity of the system distribution panel is, for example, 320.5KVA on the six sides of the main distribution panel Nos. 1 to 6 + 179.7KVA on the three sides of Nos. 7 to 9 = 500KVA, with a load rate of 73% and a surplus rate of 27%. (2) In addition to the main distribution panel, the system distribution panel of the relevant distribution panel utilizes the uses and functions of the substation equipment, cubicles, etc. of the building facility or outdoor facility, and in addition to the main distribution panel of the system of the low-voltage lighting distribution panel, system terminal electrical equipment such as additional distribution panels, shelf load equipment, etc. are operating at full capacity, and the amount of power exceeds the alarm current of 1350A, for example, the maximum current may be 1718A, and the TR capacity may be 500KVA or more.

[0236] The configuration of the main and additional low-voltage power distribution panels and systems is (1) main material handling control panels (58.1KVA for NO1 to NO10) x 5 + conveyor control panel 30.0KVA) = 320.5KVA, load factor 64%, (2) additional material handling control panels (59.9KVA for NO6 to NO8) x 3 = 179.7KVA, load factor 36%, (3) the above control panels 320.5KVA + 179.7KVA = 500.2KVA, (4) maximum current 1718A, (5) alarm current 1350A, (6) load capacity 363KW, (7) load factor 79%.

[0237] The overcurrent protection thermal relay of transformer Tr1. 3φ500kVA of low voltage power panel No.1 is installed on the secondary side of the 1500 / 5A CT of the corresponding circuit, and for example, by a 4.5A thermal relay, (1) regardless of the alarm current 1350A and maximum load factor 79%, (1)-1. For example, for the purpose of efficiency depending on the operational status of the business, the main distribution board capacity of the above-mentioned electric lighting and power low voltage distribution board is 320.5KVA + additional distribution board capacity for spare use is 179.7KVA, so the electrical capacity is 500.0KVA and the load factor is 100%, but the electrical equipment is used for both lighting and power The demand rate is not always 100%; it is usually around 70-80% for lighting and 65-75% for power. Even with the equipment contents where the capacity of the additional distribution board has been increased to a load rate of 100%, it is unlikely that the power consumption will be 100%. However, depending on the operating status of the terminal equipment, it may exceed the above-mentioned (1) alarm current of 1350A, (2) load equipment capacity of 393kw, (3) load rate of 79%, and reach (4) maximum current of 1718A and (5) maximum load rate of 100% of TR capacity of 500KVA, resulting in a TR capacity of 500KVA.

[0238] The DESCON safety control system's alarm current alarm type (1) power TR1 capacity is 500KVA, (2) the maximum current is 1718A, and the (3) alarm load current for overload prevention is 1350A, proportionally (4) the TR load equipment capacity is 393KW. This is entered into the database, and for example, a CT ammeter installed on the lamp TR detects whether the detected current is below or exceeds the (5) alarm load current of 1350A due to safety protection overcurrent, etc. If it exceeds the limit, for example, the alarm load current is treated as a caution current, and relevant information such as the customer name, building name, facility name, location, lamp, type of power, capacity, electrical equipment at the system terminal, and load equipment name is sent as an alert in the form of voice, numbers, images, etc. to the PC, tablet, smartphone, etc. of the relevant person. In addition, the alert ringtone is continuously transmitted until the relevant person confirms and resets it to prevent the relevant person from missing the confirmation, and when the detected current rises above the warning current of 1350A and is arbitrarily set in advance, (7) the alarm cutoff coefficient is, for example, 1.10, (8) the alarm cutoff current = (warning warning current 1350A AX alarm cutoff coefficient 1.10) = 1485A, (9) the maximum current load coefficient of the maximum current of 1718A = (alarm cutoff current 1485A / maximum current 1718A) = 0.86, (10) the excess rate is 14%, (11 ) If the alarm tripping current is 1485A or more, for example, (12) if the detection current is 1585A, then (13) the automatic tripping current = (detection current 1585A) - (alarm tripping current 1485A) = 95A will be automatically tripped, and for the relevant equipment capacity, (14) the automatic tripping capacity is 27.6KVA, and (15) the automatic tripping rate is 6.0% will be automatically tripped, and the order of tripping of the terminal load equipment, electrical equipment, etc. of the relevant main distribution board and additional distribution board will be determined, and the terminal load equipment, electrical equipment, etc., that can be tripped without causing any problems, as well as the relevant boards, circuits, etc. will be automatically tripped.

[0239] The DESCON safety control system can be configured to send alerts of the above-mentioned automatic shutoff to the relevant parties' PCs, tablets, smartphones, etc., including the customer name, building name, low-voltage distribution board, distribution board, control panel, circuit, etc., as well as audio, images, temperature values, etc. to terminal electrical equipment, terminal load equipment, etc., and continue to send these alerts until the relevant parties confirm that the alert has been sent, allowing the relevant parties to check safety in real time after the relevant automatic shutoff and to take subsequent action.

[0240] The DESCON Safety Control System (1) automatically shuts off various types of equipment and electrical devices, such as those in logistics centers, large freezers, refrigerators, and other products and manufacturing facilities where many people gather, as well as in terminal buildings, hotels, and other similar facilities, and in data centers for important data, research and test results, infrastructure substations, and transportation trains and ships, using computer programs such as AI and IoT. (2) When the terminal equipment and electrical devices are automatically shut off using a predetermined program, (3) when the distribution board, distribution panel, control panel, main line, circuit, breaker, etc. are connected to remote devices, cloud servers, LANs, etc., for each system, the system is automatically shut off. The DESCON safety control system, which is composed of the above, uses remote devices for each system, and an emergency response protection program via a cloud server, LAN, etc. (4) The remote devices such as the relevant distribution board, distribution board, control panel, etc. send a signal to the protection stop device, and the collective or selected terminal equipment, etc. of the control, etc. is safely protected, has the function of shutting down by program, and is characterized by a means for controlling the stop function normally and safely, and a means for confirming the stop signal.

[0241] When the current detected by the CT of a power TR with an alarm current alarm type rises above the caution alarm current of 1350A, the automatic cutoff current = (1350AX1.10) = 1485A or more will be automatically cut off at the alarm cutoff coefficient of 1.10 for the caution alarm current of 1350A, which is set arbitrarily in advance.

[0242] Alternatively, for the caution current safety type, (1) the power TR1 capacity is 500KVA, (2) the maximum current is 1718A, the (3) alarm load current for overload prevention is 1350A, and proportionally (4) the TR load equipment capacity is 393KW are entered as a database, and for example, a CT ammeter installed in a light TR detects that the detected current is an overcurrent for safety protection, (5) an alarm current exceedance is detected by the CT detection, (6) the alarm load current is 1350A, and according to a preset arbitrary value, for example, (7) caution current coefficient 0.96, (8) caution alarm current = (alarm load current 1350AX caution current coefficient 0.96) = 1296A, the safety is high, the load rate of the relevant TR decreases, and relevant information such as the customer name, building name, facility name, location, light, type of power, capacity, electrical equipment at the system terminal, and load equipment name is sent as an alert in the form of voice, numbers, images, etc. to the PC, tablet, smartphone, etc. of the relevant person to notify them. The alert ringtone can be continuously transmitted until the person concerned confirms and resets the setting, thereby preventing the person concerned from failing to confirm the setting.

[0243] In addition, the DESCON safety control system automatically shuts off the detected current when it increases to a maximum current of 1718A, which is arbitrarily set in advance, for example, (9) maximum current coefficient 0.7, (10) excess rate 30%, (11) alarm shutoff current = (maximum current 1718AX maximum current coefficient 0.86) = 1477A or more. (12) If the detected current is 1610A, (13) the automatic shutdown current = (detection current 1610A) - (alarm shutdown current 1477A) = 133A will be automatically shut off. The 133A to be automatically shut off is (14) converted to the equipment automatic shutdown capacity KVA = (current 133AX voltage 210VX power factor 0.8) / 1000A = 22KVA, and the automatic shutdown equipment capacity is 22KVA. (15) The automatic shutdown rate is 8.2%, and the order of (15) shutdown of the terminal load equipment, electrical equipment, etc. of the relevant main distribution board and additional distribution board is determined, and the terminal load equipment, electrical equipment, etc. that can be shut off without causing any problems, as well as the relevant boards, circuits, etc., will be automatically shut off.

[0244] The DESCON safety control system can be configured to send alerts of the above-mentioned automatic shutoff to the relevant parties' PCs, tablets, smartphones, etc., including the customer name, building name, low-voltage distribution board, distribution board, control panel, circuit, etc., as well as audio, images, temperature values, etc. to terminal electrical equipment, terminal load equipment, etc., and continue to send these alerts until the relevant parties confirm that the alert has been sent, allowing the relevant parties to check safety in real time after the relevant automatic shutoff and to take subsequent action.

[0245] The DESCON Safety Control System (1) automatically shuts off various types of equipment and electrical devices, such as those in logistics centers, large freezers, refrigerators, and other products and manufacturing facilities where many people gather, as well as in terminal buildings, hotels, and other similar facilities, and in data centers for important data, research and test results, infrastructure substations, and transportation trains and ships, using computer programs such as AI and IoT. (2) When the terminal equipment and electrical devices are automatically shut off using a predetermined program, (3) when the distribution board, distribution panel, control panel, main line, circuit, breaker, etc. are connected to remote devices, cloud servers, LANs, etc., for each system, the system is automatically shut off. The DESCON safety control system, which is composed of the above, has an emergency response protection program via remote devices for each system, a cloud server, LAN, etc., and (4) the remote devices such as the relevant distribution board, distribution board, control panel, etc. send a signal to the protection stop device, and the control etc. is safely protected as a whole or selected terminal equipment, etc., and has the function of shutting down by program, and can be configured to have a means for controlling the stop function normally and safely, and a means for confirming the stop signal.

[0246] When the current detected by the CT of a caution current safety type electric light TR rises above the caution alarm current of 1296A, the automatic cut-off current = (maximum current 1718AX0.86) = 1477A or more is automatically cut off at a preset maximum current coefficient of 0.86 of 1718A.

[0247] The heat resistance characteristics of transformers (hereinafter referred to as "transformers") in power receiving and transforming equipment are as follows.

[0248] Transformers are classified into heat resistance classes shown in Table 2 according to the heat resistance properties of the insulating materials used.

[0249] Insulating materials include (1) insulating oil, (2) SF6 gas, (3) kraft paper, (4) pressboard, (5) mica, (6) glass fiber, (7) epoxy resin, (8) silicone resin, and (9) alkyd resin, and the maximum allowable temperatures for (1) insulating oil through (9) alkyd resin are specified. In addition, the heat resistance class for oil-filled transformers using the above-mentioned various insulating materials is A, and for molded transformers, B, F, and H are applied.

[0250] When used under standard conditions, transformers are designed so that the temperature rise limit of the windings (the difference between the winding temperature and the ambient temperature) is not exceeded and the temperature of each part of the insulation does not exceed the maximum allowable temperature of the heat resistance class. However, if the ambient temperature exceeds the maximum value of 40°C or if the transformer is operated under excessive overload, the maximum allowable temperature may be exceeded.

[0251] Since the lifespan of a transformer is most significantly affected by its maximum temperature, prolonged continuous operation above the maximum allowable temperature will shorten the expected lifespan of a transformer from 30 years. Standard operating conditions are as follows:

[0252] The transformer environment, configuration, etc. are as follows:

[0253] (1) Use at an altitude of 1,000 m or less. (2) Ambient temperature: Indoors -5°C to +40°C, outdoors -20°C to +40°C, with the daily average temperature not exceeding 35°C and the annual average temperature not exceeding 20°C. (3) Circuit voltage waveform The voltage waveform of the circuit to which the transformer is connected shall be approximately sinusoidal. (4) Voltage balance of a three-phase circuit A three-phase circuit to which a three-phase transformer is connected is nearly balanced. (5) The reference winding temperature is defined as the reference temperature for calculating characteristic values ​​such as load loss and short-circuit impedance, since the resistance value changes depending on the winding temperature.

[0254] Heat resistance class and temperature of insulating materials for TR transformers in power receiving and transforming equipment Japan Electrical Manufacturers' Association Standard No.: JEM 1310:2001 The temperature rise limit and standard winding temperature (heat resistance class H) for dry-type transformers is 140K.

[0255] The reference winding temperature is determined as a reference temperature for calculating characteristics such as load loss and short-circuit impedance, since the resistance value changes depending on the winding temperature.

[0256] 6kV oil-filled distribution transformer (JIS C 4303 1999), oil-filled reactor (JIS 4902 2003) 6kV distribution transformer (JIS C 4306) TR (1) The boiling point of insulating oil is said to be around 290℃ to 340℃.

[0257] The diagram shows the voltage, TR capacity, thermal relay, circuit current, equipment capacity, etc. of the building's power receiving and transforming equipment, such as three lighting transformers (hereafter referred to as TRs) and four power transformers (hereafter referred to as TRs), as well as the program for automatic shutdown of the distribution board, circuits, terminal electrical equipment, and load equipment in the system based on detected temperatures.

[0258] In the above (1) electric lighting TR 200KVA, for example, in the system of the low voltage lighting distribution panel, the main distribution panel No. 1 25.0KVAAX No. 4 4 panels + No. 5 20KVA + No. 6 25.0KVA, and the additional No. 7 27.5KVA + No. 8 27.5KVA, (1) the capacity of the main distribution panel is 145kw + additional distribution panel 55kw = distribution panel capacity 200.KVA, (2) the maximum current is 952A, and the (3) alarm current of the safety protection thermal relay is 780A, (3) proportionally the load equipment capacity of the TR is 164kw, and the load factor is 82%, (4) the capacity of the main + additional distribution panel is 200KVA, which is 100% of the TR capacity 200KVA, but the (5) load equipment capacity of the thermal relay is 82% of (6) 164KVA.

[0259] By adding terminal load equipment with a capacity exceeding 100% of the power capacity of the low-voltage lighting distribution panel or the system terminal load equipment, the distribution panel of the relevant equipment becomes the main distribution panel, and the additional distribution panel is installed at 100% of the capacity of the TR of 200KVA and the maximum current of 952A, or when the terminal load equipment is operated by installing a main distribution panel that exceeds 100%, (4) for example, the TR capacity of 200KVA may be exceeded and the maximum allowable temperature of 105°C for insulation type A may be exceeded.

[0260] The (1) allowable maximum temperature for the insulation type of the electric lighting transformer of the safe allowable temperature type is 105℃ for type A, 120℃ for type E, 130℃ for type B, 155℃ for type F, and 180℃ for type H. The temperature sensor installed in the TR judges whether the (2) detected temperature exceeds the corresponding allowable maximum temperature or is below the allowable maximum temperature based on the allowable maximum temperature of the corresponding type A to H. Alternatively, the temperature sensor judges whether the (3) detected temperature of each type A to H is below the allowable maximum temperature. For example, the (4) safety temperature coefficient 0.97 is set as the safety caution temperature in advance. For example, if the (5) type A TR detects = (A type allowable maximum temperature 105℃ x 0.97) = safety caution temperature 102℃, the relevant information such as the customer name, building name, facility name, location, electric light, operation of the TR, etc. will be sent to the PC, tablet, smartphone, etc. of the person in charge. The type and capacity of the power, the name of the electrical equipment load equipment at the system terminal, etc. are sent as an alert in the form of voice, numbers, images, etc., and the alert ringtone is sent continuously until the relevant person confirms and resets it to prevent the relevant person from missing the confirmation. Also, when the detected temperature rises above the safety caution temperature of 102°C, for example, the detected temperature rises above the safety caution temperature of 102°C, which is set arbitrarily in advance, (6) the alarm cutoff temperature coefficient is, for example, 1.10, (7) the alarm cutoff temperature = safety caution temperature 102°C x alarm temperature coefficient 1.10 = 112.2.

[0261] For example, (8) when the detected temperature is 132°C, (9) the automatic shutdown temperature = (detected temperature 132°C - alarm shutdown temperature 112.2°C) = 19.8°C, (10) the automatic shutdown rate = 1 - (alarm shutdown temperature 112.2°C / detected temperature 132°C) = 15%, is automatically shut off, and the order of (11) shutdown of the terminal load equipment, electrical equipment, etc. of the relevant main distribution board and additional distribution board is determined, and by automatically shutting off the relevant distribution board, control panel, circuit, etc., and terminal load equipment, electrical equipment, etc. that will not cause any problems when shut off, the (12) current value that energizes the relevant TR is reduced, and the TR temperature (13) decreases in proportion to the current value due to the reduction in the thermal load of the electrical resistance.

[0262] Furthermore, as described above, the DESCON safety control system (14) automatically shuts off the distribution boards, control panels, circuits, etc., terminal load equipment, electrical equipment, etc. of the TR system when the detection temperature is 132°C, but if the preset (15) alarm cutoff temperature does not reach 112.2°C, (16) the automatic cutoff program will automatically cut off the relevant distribution boards, control panels, circuits, etc., terminal load equipment, electrical equipment, etc. until the alarm cutoff temperature of 112.2°C is reached, and conversely, the system can be configured to have a means to stop the automatic cutoff if the alarm cutoff temperature reaches 112.2°C even while the system is shutting down by the program.

[0263] (1) The DESCON safety control system can be configured to have a means for automatically shutting off the relevant distribution boards, control panels, circuits, and other terminal load equipment, electrical devices, etc. in order of shutoff when the alarm shutoff temperature exceeds 112.2°C, for example, (17) the current value at the time of the detection temperature of 132°C, (18) the detected current value is 938A, (19) the automatic shutoff temperature is 19.8°C, and the automatic shutoff rate is 15%, and the relevant distribution boards, control panels, circuits, etc. and terminal load equipment, electrical devices, etc. are shut off without causing any problems, for example, (2(1) detected shutoff current A = (detection current 938AX automatic shutoff rate 15%) = 140.7A)

[0264] (2) Furthermore, the DESCON safety control system can be configured such that, for example, if the (23) detection current is 920A when the (22) detection temperature is 132°C, the (24) alarm cutoff temperature is 112.2°C, the (25) automatic cutoff temperature is 19.8°C, and the (26) automatic cutoff rate is 15%, the (27) automatic cutoff current = (detection current 920AX automatic cutoff rate 15%) = 138A. The system can be configured to input the detection current at the cutoff detection temperature, automatically input the automatic cutoff current, and automatically cut off the circuit according to a predetermined program.

[0265] The DESCON Safety Control System (1) automatically shuts off various types of equipment and electrical devices, such as those used in logistics centers, large freezers, refrigerators, and other products and manufacturing facilities where many people gather, terminal buildings, hotels, and other similar facilities, as well as data centers for important data, research and test results, infrastructure substations, and transportation trains and ships, etc., using computer programs such as AI and IoT. (2) When the terminal equipment and electrical devices are automatically shut off by a predetermined program, the terminal equipment and electrical devices are automatically shut off by a predetermined program. (3) When the terminal equipment and electrical devices are automatically shut off by a predetermined program, the terminal equipment and electrical devices are automatically shut off by a predetermined program. The DESCON safety control system, which is composed of remote devices for each system, such as control panels, main lines, circuits, breakers, etc., as well as cloud servers, LANs, etc., uses an emergency response protection program via remote devices for each system, cloud servers, LANs, etc. (4) The remote devices, such as the relevant distribution boards, distribution boards, control panels, etc., send a signal to the protection stop device, and the control equipment, etc., as a whole or selected terminal equipment, etc., is safely protected, and has the function of shutting down by program, and can be configured to have a means for controlling the stop function normally and safely, and a means for confirming the stop signal.

[0266] When the current detected by the CT of a safety allowable temperature type electric light TR rises above the safety caution temperature of 102°C, the alarm tripping coefficient for the safety caution temperature of 102°C, which is set arbitrarily in advance, is 1.10, and the alarm tripping temperature = (1102.2 x 1.10) = 112.2°C is tripped.

[0267] The (1) allowable maximum temperature for the insulation type of the electric lighting transformer of the alarm allowable temperature type is A type 105℃, E type 120℃, B type 130℃, F type 155℃, and H type 180℃. The temperature sensor installed in the TR judges whether the (2) detected temperature exceeds the allowable maximum temperature or is below the allowable maximum temperature based on the allowable maximum temperature value of the corresponding A type to H type, or whether the detected temperature is below the allowable maximum temperature based on the (3) allowable maximum temperature value of the above A type to H type. For example, the (4) alarm temperature coefficient can be arbitrarily set in advance. For example, when the alarm temperature of (5) A-class TR = (A-class maximum allowable temperature 105°C x 1.0) = alarm allowable temperature 105°C is detected, an alert is sent to the PC, tablet, smartphone, etc. of the relevant person with the relevant information such as the customer name, building name, facility name, location, TR light, power type capacity, and load equipment name of the electrical equipment of the system terminal in the form of voice, numerical value, image, etc., and the alert ringtone is sent continuously until the relevant person confirms and resets, preventing the relevant person from missing the confirmation. If the detected temperature exceeds the alarm allowable temperature of 105°C and is arbitrarily set in advance, for example, the (6) alarm cutoff temperature coefficient is 1.10, (7) alarm cutoff temperature = (alarm temperature or allowable maximum temperature 105°C x alarm cutoff coefficient 1.10) = 115.5°C, and the alarm cutoff temperature is, for example, (9) if the detected temperature is 132°C, then (9) automatic cutoff temperature = (detected temperature 132°C - alarm cutoff temperature 115.5°C = 16.5°C, (10 ) Automatic shutdown rate = 1 - (alarm shutdown temperature 115.5℃ / detection temperature 132℃) = 13%, and (11) the shutdown order of the relevant main distribution board, additional distribution board terminal load equipment, electrical equipment, etc. is determined, and by automatically shutting off the relevant distribution board, control panel, circuit, etc., and terminal load equipment, electrical equipment, etc. that will not cause any problems when shut off, the relevant TR is powered by reducing the (12) current value, and the TR temperature decreases in proportion to the current value due to the reduction in the thermal load of the electrical resistance, and (13) the TR temperature decreases.

[0268] Furthermore, as described above, the DESCON safety control system (14) automatically shuts off the distribution boards, control panels, circuits, etc. of the TR system, terminal load equipment, electrical equipment, etc., when the detection temperature is 132°C, but if the preset (15) alarm cutoff temperature does not reach 112.2°C, (16) the automatic cutoff program will automatically cut off the relevant distribution boards, control panels, circuits, etc., terminal load equipment, electrical equipment, etc., until the alarm cutoff temperature reaches 115.5°C. Conversely, the system can be configured to have a means to stop the automatic cutoff if the alarm cutoff temperature reaches 115.5°C even while the system is shutting down by the program.

[0269] The DESCON Safety Control System can be configured to have a means for automatically shutting off terminal load equipment, electrical devices, etc., such as the relevant main distribution board, additional distribution board, circuits, etc., in order of shutoff when the alarm cutoff temperature of 115.5°C is exceeded, for example, when the current value at the (17) detection temperature is 132°C, and the (18) detection current value is 938A, the (19) automatic cutoff temperature is 16.5°C, with an automatic cutoff rate of 13%, and automatically shutting off the relevant distribution board, control panel, circuits, etc., and terminal load equipment, electrical devices, etc., that can be shut off without causing any problems, for example, when the (19) detection current value is 938A, and the (20) automatic cutoff rate is 13%, the (2(1) detection cutoff current A = (detection current 938AX automatic cutoff rate 13%) = 121.9A.

[0270] The DESCON safety control system can be configured to have a means for automatically inputting the detection current at the time of the shutdown detection temperature, automatically inputting the automatic shutdown current, and automatically shutting down the system according to a predetermined program. For example, if the detection current is 920A when the detection temperature is 132°C, the automatic shutdown temperature is 115.5°C when the automatic shutdown temperature is 16.5°C, and the automatic shutdown rate is 13%, the automatic shutdown current is 110A when the detection temperature is 132°C.

[0271] The DESCON Safety Control System (1) automatically shuts off various types of equipment and electrical devices, such as those used in logistics centers, large freezers, refrigerators, and other products and manufacturing facilities where many people gather, terminal buildings, hotels, and other similar facilities, as well as data centers for important data, research and test results, infrastructure substations, and transportation trains and ships, etc., using computer programs such as AI and IoT. (2) When the terminal equipment and electrical devices are automatically shut off by a predetermined program, the terminal equipment and electrical devices are automatically shut off by a predetermined program. (3) When the terminal equipment and electrical devices are automatically shut off by a predetermined program, the terminal equipment and electrical devices are automatically shut off by a predetermined program. The DESCON safety control system, which is composed of remote devices for each system, such as control panels, main lines, circuits, breakers, etc., as well as cloud servers, LANs, etc., uses an emergency response protection program via remote devices for each system, cloud servers, LANs, etc. (4) The remote devices, such as the relevant distribution boards, distribution boards, control panels, etc., send a signal to the protection stop device, and the control equipment, etc., as a whole or selected terminal equipment, etc., is safely protected, and has the function of shutting down by program, and can be configured to have a means for controlling the stop function normally and safely, and a means for confirming the stop signal.

[0272] When the current detected by the CT of a safety allowable temperature type electric light TR rises above the safety caution temperature of 102°C, the alarm cutoff coefficient for the safety caution temperature of 102°C is 1.10, and the alarm cutoff temperature = (1102.2 x 1.10) = 112.2°C or higher is automatically cut off. The program is as shown in the figure.

[0273] For example, the voltage of four power transformers (hereafter referred to as TRs) in the building's power receiving and transforming equipment, TR capacity, thermal relays, circuit current, equipment capacity, etc., as well as the program for automatic shutdown of the distribution board, circuits, terminal electrical equipment, and load equipment in the system based on detected temperatures are as shown in the figure.

[0274] The DESCON safety control system is configured for the six pieces of equipment (1) with the power TR of 500KVA, and the low voltage power distribution panel system is, for example, five panels of main distribution panel No. 1 58.1KVA and No. 6 + 30.0KVA of No. 6, and additional panels No. 7 59.9KVA + No. 8 59.9KVA + No. 9 59.9KVA, for a total capacity of 320.5kw + additional distribution panel 179.7kw = distribution panel capacity 500.2KVA, (1) TR capacity 500KVA, maximum current 1718A, (2) alarm current of the safety thermal relay is 1350A, (3) load factor is 79%, (4) The capacity of the main + additional distribution board is 500KVA, which is 100% of the TR capacity of 500KVA, but (5) the load equipment capacity of the thermal relay is 79% of 393KVA.

[0275] As stated above, (1) the transformer Tr1. 3φ500kVA on the low-voltage power panel No. 1, (2) the maximum current is 1718A, and the low-voltage power distribution panel for the No. 1 system is the first floor power (3) distribution panels No. 1 to No. 6, the main distribution panel is 320.5kVA, load factor 64%, and the additional distribution panel is 179.7kVA, load factor 36%, so the capacity of the main and additional distribution panels is 500kVA, and the maximum load factor is 100%. However, (1) the total of the main distribution panel 320.5kVA and additional distribution panel 179.7kVA on the system of the low-voltage power panel is 500kVA, and (2) the current value is 1718A. (3) As described above, the demand utilization rate of the lighting equipment is 65% to 75% of its capacity (500KVAX 65% to 75%) = 325KVA to 375KVA, and the operating demand current A = (maximum current 1718AX 65% to 75%) = 1116A to 1288A. (4) Working backwards, this leaves a margin of around 35% to 25%.

[0276] In addition, by adding terminal load equipment with a capacity exceeding 100% of the power capacity of the low-voltage power distribution panel or the system terminal load equipment, the distribution panel of the relevant equipment becomes the main distribution panel, and the additional distribution panel is installed at 100% of the capacity of the TR of 500KVA and maximum current of 1718A, or when the terminal load equipment is operated by installing a main distribution panel that exceeds 100%, (4) for example, the TR capacity of 200KVA may be exceeded and the maximum allowable temperature of insulation type A, 105°C, may be exceeded.

[0277] The maximum allowable temperature for the insulation type of the electric lighting transformer of the safe allowable temperature type is (1) A type 105℃, E type 120℃, B type 130℃, F type 155℃, H type 180℃. The maximum allowable temperature of the temperature sensor installed in the TR is based on the allowable maximum temperature of the corresponding A to H type. (2) It is determined whether the detected temperature exceeds the corresponding maximum allowable temperature or is below the maximum allowable temperature, or (3) based on each maximum allowable temperature value of the above-mentioned A to H types, for example, (4) a safety temperature coefficient of 0.97 is arbitrarily set in advance as a safety caution temperature. For example, (5) when a Type A TR detects = (Type A maximum allowable temperature 105°C x 0.97) = safety caution temperature 102°C, an alert is sent to the PC, tablet, smartphone, etc. of the relevant person with the corresponding information such as the customer name, building name, facility name, location, TR light, power type and capacity, and the name of the electrical equipment load equipment of the system terminal, in the form of voice, numerical value, image, etc., and the alert ringtone is continuously sent until the relevant person confirms and resets, preventing the relevant person from missing the confirmation. Also, when the detected temperature rises above the safety caution temperature of 102°C and the detected temperature For example, if the safety caution temperature rises above 102°C and is arbitrarily set in advance, (6) the alarm cutoff temperature coefficient is, for example, 1.10, and (7) the alarm cutoff temperature = safety caution temperature 102°C x alarm temperature coefficient 1.10 = 112.2.

[0278] For example, (8) when the detected temperature is 132°C, (9) the automatic shutdown temperature = (detected temperature 132°C - alarm shutdown temperature 112.2°C) = 19.8°C, (10) the automatic shutdown rate = 1 - (alarm shutdown temperature 112.2°C / detected temperature 132°C) = 15%, is automatically shut off, and the order of (11) shutdown of the terminal load equipment, electrical equipment, etc. of the relevant main distribution board and additional distribution board is determined, and by automatically shutting off the relevant distribution board, control panel, circuit, etc., and terminal load equipment, electrical equipment, etc. that will not cause any problems when shut off, the (12) current value that energizes the relevant TR is reduced, and the TR temperature (13) decreases in proportion to the current value due to the reduction in the thermal load of the electrical resistance.

[0279] As described above, the DESCON safety control system (14) automatically shuts off the distribution boards, control panels, circuits, etc., terminal load equipment, electrical equipment, etc. of the TR system when the detection temperature is 132°C, but if the preset (15) alarm cutoff temperature does not reach 112.2°C, (16) the automatic cutoff program will automatically cut off the relevant distribution boards, control panels, circuits, etc., terminal load equipment, electrical equipment, etc. until the alarm cutoff temperature of 112.2°C is reached, and conversely, if the alarm cutoff temperature reaches 112.2°C even while the system is shutting down by the program, the automatic cutoff will be stopped. (16) The alarm tripping program can be configured to have a means for automatically tripping (21) the relevant distribution board, control panel, circuit, etc., terminal load equipment, electrical equipment, etc., when the alarm tripping temperature exceeds 112.2°C, for example, (17) the current value at the time of the detection temperature of 132°C, (18) the detected current value is 1620A, (19) the automatic tripping temperature is 19.8°C, and the automatic tripping rate is 18%, for example, when the detection current value is 1620A, (20) the automatic tripping rate is 18%, and (21) the detected tripping current A = (detection current 1620AX automatic tripping rate 18%) = 291.6A.

[0280] In addition, the DESCON safety control system can be configured such that, for example, if the (23) detection current is 1590A when the (22) detection temperature is 132°C, the (24) alarm cutoff temperature is 112.2°C, the (25) automatic cutoff temperature is 19.8°C, and the (26) automatic cutoff rate is 18%, the (27) automatic cutoff current = (detection current 1590AX automatic cutoff rate 18%) = 286A.The system can be configured to input the detection current at the cutoff detection temperature, automatically input the automatic cutoff current, and automatically cut off using a predetermined program.

[0281] The DESCON safety control system is designed to automatically shut off the above-mentioned terminal equipment, such as terminal equipment for electrical equipment, for example, products, manufacturing, etc., logistics centers, large freezers, refrigerators, etc., commercial facilities where many people gather, terminal equipment for electrical equipment, lighting, elevators, etc. in terminal equipment for electrical equipment, data centers for important data, research and test results, etc., infrastructure substations, and various facilities and electrical equipment for transportation such as trains and ships, etc., by computer programs such as AI and IoT. (1) Program control, terminal equipment for shutting off, etc. is predetermined. (2) When automatic shutoff is performed by a program, (3) distribution boards, distribution boards, control panels, main lines, circuits, etc. The DESCON safety control system, which is composed of remote devices for each system, such as circuits and breakers, a cloud server, a LAN, etc., (3) uses the remote devices for each system, a cloud server, a LAN, etc. to (4) send a signal from the relevant remote device such as the distribution board, panel board, control panel, etc. to the protection stop device, and the control of all or selected terminal equipment, etc. is safely protected by (4) a program (5) has the function of shutting down, (6) has a means for safely and accurately (7) a stop function control means, and (8) can be configured to have a function for confirming the stop signal.

[0282] When the current detected by the CT of a safety allowable temperature type electric light TR rises above the safety caution temperature of 102°C, the alarm cutoff coefficient for the safety caution temperature of 102°C is 1.10, and the alarm cutoff temperature = (102.2 x 1.10) = 112.2°C or higher is automatically cut off. The program is as shown in the figure.

[0283] The (1) allowable maximum temperature for the insulation type of the electric lighting transformer of the alarm allowable temperature type is 105℃ for type A, 120℃ for type E, 130℃ for type B, 155℃ for type F, and 180℃ for type H. The allowable maximum temperature of the corresponding type A to type H is used as a reference to determine whether the (2) detected temperature of the temperature sensor installed in the TR exceeds the corresponding allowable maximum temperature or is below the allowable maximum temperature. Alternatively, the (3) allowable maximum temperature value of each type A to type H is used as a reference to determine whether the (4) alarm temperature coefficient is set arbitrarily in advance as a safety caution temperature. For example, if the alarm temperature of type A TR = (type A allowable maximum temperature 105℃ x 1.0) = alarm allowable temperature 105℃ is detected, the relevant An alert is sent to the PC, tablet, smartphone, etc. of the person in charge, including, for example, the customer name, building name, facility name, location, TR light, power type and capacity, and the name of the electrical equipment load equipment at the system terminal, in the form of voice, numbers, images, etc., and the alert ringtone is sent continuously until the person in charge confirms and resets it to prevent the person in charge from missing the confirmation.In addition, when the detected temperature rises above the alarm allowable temperature of 105°C, for example, the alarm cutoff temperature coefficient is set to, for example, 1.15, and (7) the alarm cutoff temperature = (alarm temperature or allowable maximum temperature 105°C x alarm cutoff coefficient 1.15) = 121°C.

[0284] For example, (8) when the detected temperature is 140°C, (9) the automatic shutdown temperature = (detected temperature 140°C - alarm shutdown temperature 121°C) = 19.0°C, (10) the automatic shutdown rate = 1 - (alarm shutdown temperature 121°C / detected temperature 140°C) = 14%, and (11) the shutdown order of the relevant main distribution board, additional distribution board, terminal load equipment, electrical equipment, etc. is determined, and by automatically shutting off the relevant distribution board, control panel, circuit, etc., and terminal load equipment, electrical equipment, etc., which can be shut off without causing any problems, the TR temperature decreases in proportion to the current value by reducing the current value (12).

[0285] As described above, the DESCON safety control system (14) automatically shuts off the distribution boards, control panels, circuits, etc. of the TR system, terminal load equipment, electrical equipment, etc., when the detection temperature is 140°C, but if the preset (15) alarm cutoff temperature does not reach 121°C, (16) the automatic cutoff program will automatically cut off the relevant distribution boards, control panels, circuits, etc., terminal load equipment, electrical equipment, etc., until the alarm cutoff temperature of 121°C is reached. Conversely, the system can be configured to have a means to stop the automatic cutoff if the alarm cutoff temperature of 121°C is reached even while the system is shutting down by the program.

[0286] (16) The alarm tripping program can be configured to have a means for automatically tripping the relevant main distribution board, additional distribution board, terminal load equipment such as circuits, electrical equipment, etc., when the alarm tripping temperature exceeds 121°C, for example, (17) the current value at the detection temperature of 140°C, (18) the detection current value is 1620A, (19) the automatic tripping temperature is 19.0°C, and the automatic tripping rate is 14%, for example, the relevant distribution board, control panel, circuit, etc., and terminal load equipment, electrical equipment, etc., which can be tripped in order to trip without causing any problems, for example, if the (19) detection current value is 1620A, (20) the automatic tripping rate is 14%, and (21) the detection tripping current A = (detection current 1620AX automatic tripping rate 14%) = 226.8A.

[0287] The DESCON safety control system can be configured to have a means for automatically inputting the detection current at the time of the shutdown detection temperature, automatically inputting the automatic shutdown current, and automatically shutting down the system according to a predetermined program. For example, if the detection temperature is 140°C and the detection current is 1620A, the alarm shutdown temperature is 115.5°C, the automatic shutdown temperature is 19.0°C, and the automatic shutdown rate is 14%, the automatic shutdown current is 226.8A.

[0288] The DESCON safety control system is designed to automatically shut off the above-mentioned terminal equipment, such as terminal equipment for electrical equipment, for example, products, manufacturing, etc., logistics centers, large freezers, refrigerators, etc., commercial facilities where many people gather, terminal equipment for electrical equipment, lighting, elevators, etc. in terminal equipment for electrical equipment, data centers for important data, research and test results, etc., infrastructure substations, and various facilities and electrical equipment for transportation such as trains and ships, etc., by computer programs such as AI and IoT. (1) Program control, terminal equipment for shutting off, etc. is predetermined. (2) When automatic shutoff is performed by a program, (3) distribution boards, distribution boards, control panels, main lines, circuits, etc. The DESCON safety control system, which is composed of remote devices for each system, such as circuits and breakers, a cloud server, a LAN, etc., (3) uses the remote devices for each system, a cloud server, a LAN, etc. to (4) send a signal from the relevant remote device such as the distribution board, panel board, control panel, etc. to the protection stop device, and the control of all or selected terminal equipment, etc. is safely protected by (4) a program (5) has the function of shutting down, (6) has a means for safely and accurately (7) a stop function control means, and (8) can be configured to have a function for confirming the stop signal.

[0289] When the current detected by the CT for an electric light TR of an alarm tolerance temperature type rises above the maximum allowable temperature and the alarm tolerance temperature is set to 105°C, the alarm cutoff coefficient is 1.15, and the temperature will automatically cut off at an alarm cutoff temperature of (105 x 1.15) = 121°C or higher.The program is as shown in the figure.

[0290] The (1) allowable maximum temperature for the insulation type of the electric lighting transformer of the alarm allowable temperature type is A type 105℃, E type 120℃, B type 130℃, F type 155℃, and H type 180℃. The temperature sensor installed in the TR judges whether the (2) detected temperature exceeds the allowable maximum temperature or is below the allowable maximum temperature based on the allowable maximum temperature value of the corresponding A type to H type, or whether the detected temperature is below the allowable maximum temperature based on the (3) allowable maximum temperature value of the above A type to H type. For example, the (4) alarm temperature coefficient can be arbitrarily set in advance. For example, when the alarm temperature of (5) A-class TR = (A-class maximum allowable temperature 105°C x 1.0) = alarm allowable temperature 105°C is detected, an alert is sent to the PC, tablet, smartphone, etc. of the relevant person with the relevant information such as the customer name, building name, facility name, location, TR light, power type capacity, and load equipment name of the electrical equipment of the system terminal in the form of voice, numerical value, image, etc., and the alert ringtone is sent continuously until the relevant person confirms and resets, preventing the relevant person from missing the confirmation. If the detected temperature exceeds the alarm allowable temperature of 105°C and is arbitrarily set in advance, for example, the (6) alarm cutoff temperature coefficient is 1.10, (7) alarm cutoff temperature = (alarm temperature or allowable maximum temperature 105°C x alarm cutoff coefficient 1.10) = 115.5°C, and the alarm cutoff temperature is, for example, (9) if the detected temperature is 132°C, then (9) automatic cutoff temperature = (detected temperature 132°C - alarm cutoff temperature 115.5°C = 16.5°C, (10 ) Automatic shutdown rate = 1 - (alarm shutdown temperature 115.5℃ / detection temperature 132℃) = 13%, and (11) the shutdown order of the relevant main distribution board, additional distribution board terminal load equipment, electrical equipment, etc. is determined, and by automatically shutting off the relevant distribution board, control panel, circuit, etc., and terminal load equipment, electrical equipment, etc. that will not cause any problems when shut off, the relevant TR is powered by reducing the (12) current value, and the TR temperature decreases in proportion to the current value due to the reduction in the thermal load of the electrical resistance, and (13) the TR temperature decreases.

[0291] As described above, the DESCON safety control system (14) automatically shuts off the distribution boards, control panels, circuits, etc. of the TR system, terminal load equipment, electrical equipment, etc., when the detection temperature is 132°C, but if the preset (15) alarm cutoff temperature does not reach 115.5°C, (16) the automatic cutoff program will automatically cut off the relevant distribution boards, control panels, circuits, etc., terminal load equipment, electrical equipment, etc., until the alarm cutoff temperature of 115.5°C is reached. Conversely, the system can be configured to have a means to stop the automatic cutoff if the alarm cutoff temperature reaches 115.5°C even while the system is shutting down by the program.

[0292] The DESCON Safety Control System can be configured to have a means for automatically shutting off terminal load equipment, electrical devices, etc., such as the relevant main distribution board, additional distribution board, circuits, etc., in order of shutoff when the alarm cutoff temperature of 115.5°C is exceeded, for example, when the current value at the (17) detection temperature is 132°C, and the (18) detection current value is 938A, the (19) automatic cutoff temperature is 16.5°C, with an automatic cutoff rate of 13%, and automatically shutting off the relevant distribution board, control panel, circuits, etc., and terminal load equipment, electrical devices, etc., that can be shut off without causing any problems, for example, when the (19) detection current value is 938A, and the (20) automatic cutoff rate is 13%, the (2(1) detection cutoff current A = (detection current 938AX automatic cutoff rate 13%) = 121.9A.

[0293] The DESCON safety control system can be configured to have a means for automatically shutting down the system using a shutdown detection program, where (22) when the detection temperature is 132°C and (23) the detection current is 920A, (24) the alarm shutdown temperature is 115.5°C, (25) the automatic shutdown temperature is 16.5°C, (26) the automatic shutdown rate is 13%, and (27) the automatic shutdown current = (detection current 920AX automatic shutdown rate 13%) = 110A.

[0294] The DESCON safety control system is designed to automatically shut off the above-mentioned terminal equipment, such as terminal equipment for electrical equipment, for example, products, manufacturing, etc., logistics centers, large freezers, refrigerators, etc., commercial facilities where many people gather, terminal equipment for electrical equipment, lighting, elevators, etc. in terminal equipment for electrical equipment, data centers for important data, research and test results, etc., infrastructure substations, and various facilities and electrical equipment for transportation such as trains and ships, etc., by computer programs such as AI and IoT. (1) Program control, terminal equipment for shutting off, etc. is predetermined. (2) When automatic shutoff is performed by a program, (3) distribution boards, distribution boards, control panels, main lines, circuits, etc. The DESCON safety control system, which is composed of remote devices for each system, such as circuits and breakers, a cloud server, a LAN, etc., can be configured to (3) have an emergency response protection program, (4) send a signal from the relevant remote device such as the distribution board, panel board, control panel, etc. to the protection stop device, and (5) have the function of shutting down all or selected terminal equipment, etc., such as control equipment, etc., safely and accurately, (6) have (7) a stop function control means, and (8) have a function of confirming the stop signal, by (4) a remote device such as the relevant distribution board, panel board, control panel, etc., sends a signal to the protection stop device, and (5) have the function of shutting down all or selected terminal equipment, etc., such as control equipment, safely and accurately, by (6) a cloud server, a LAN, etc., and (8) have a function of confirming the stop signal.

[0295] The program shown in the figure automatically shuts off temperatures above (105°C x 1.10) = 115.5°C when the detection current detected by the CT for a power TR of alarm tolerance temperature type rises above the alarm tolerance temperature of 105°C and the alarm shutoff coefficient for the alarm tolerance temperature of 105°C is 1.10, which is set arbitrarily in advance.

[0296] Regardless of the above, the DESCON safety control system detects that the boiling point temperature of TR insulating oil is approximately 290°C to 340°C, and the allowable maximum temperatures for each type of TR insulation are 105°C for type A, 120°C for type E, 130°C for type B, 155°C for type F, and 180°C for type H. If the boiling point temperature of the TR or the allowable maximum temperatures are exceeded, the TR insulating oil will reach its (2) upper limit temperature, such as (1) the boiling point temperature of 290°C to 340°C, and (3) temperature sensors will be installed in the electric light and power TR. Alarm temperatures can also be set in advance as desired, such as the boiling point temperature of 290°C to 340°C and the upper limit temperature.

[0297] For example, of the four power transformers (hereinafter referred to as TRs) in a building's power receiving and substation equipment, the capacity of power TR No. 1, the thermal relay, circuit current, equipment capacity, etc., as well as the detected temperature and cut-off coefficient of the main distribution board are as shown in the figure.

[0298] Regardless of the above, the DESCON Safety Control System takes into account the load capacity of the system's low-voltage distribution board, distribution board, circuits, etc. in the permanent design documents for the surrounding environment of the power receiving and transforming equipment, lighting and power TR, or the capacity KVA of the TR, and the additional capacity due to the usage status of the system's electrical equipment, mechanical equipment, terminal load equipment, etc., and adds it. For example, as shown in 6-13, when the No. 1 power TR is at or exceeds 100% load of 500 KVA and maximum current of 1718 A, and when the ambient temperature of the surrounding environment of the TR is abnormally high, for example, the (1) boiling point temperature of the insulating oil of the TR is usually about 290°C to 340°C, the system will set (2) 290°C as the optional boiling point caution temperature and (3) 300°C as the absolute alarm temperature of the insulating oil. If the TR is the aforementioned 290°C or a preset boiling point temperature, for example, 290°C, (3) coefficient 0.40...0.9 etc. can be used = (set 290°C x arbitrary coefficient 0.62...0.90) = (4) caution temperature 180.0°C to 261°C etc. of the insulating oil, (5) the allowable maximum temperature 180°C can be arbitrarily set as the boiling point caution temperature, for example, and when the detection temperature is detected at 180°C, (6) the boiling point caution temperature is set as the boiling point caution temperature and an alert is sent to the PC, tablet, smartphone, etc. of the relevant person with the relevant information, such as the customer name, building name, facility name, location of the TR, light, power type, capacity, electrical equipment at the system terminal, and load equipment name, in the form of voice, numbers, images, etc., and the alert is sent continuously until the relevant person confirms the alert transmission, thereby preventing electrical burnout and fire accidents.

[0299] The DESCON safety control system detects the boiling point of insulating oil, which is usually between 290°C and 340°C, and detects the boiling point of insulating oil when the boiling point exceeds the boiling point caution temperature of, for example, 180°C. (3) For example, if the boiling point temperature is 290°C, then (4) the boiling point automatic shut-off coefficient = (boiling point temperature 290°C x 0.70 to 0.90, etc.), (5) the boiling point shut-off temperature is 203°C to 261°C, etc., and (6) for example, if the boiling point temperature is 340°C, then (7) the boiling point automatic shut-off coefficient = (boiling point temperature 340°C x 0.70 to 0.90, etc.) = (8) when the boiling point automatic shut-off temperature is detected as 238°C to 306°C, etc., the power supply to the system distribution board, terminal load electrical equipment, terminal load equipment, etc. of the corresponding low-voltage distribution board can be automatically shut off in advance to select the circuits of the corresponding board so that no problems will occur, and the priority order of the automatic shut-off distribution board, control panel, circuits, etc. and the terminal load electrical equipment, terminal load equipment, etc. can be determined, and a means can be provided to automatically shut off the distribution board, control panel circuits, etc., terminal load electrical equipment, terminal load equipment, etc. until the detected temperature reaches a predetermined temperature.

[0300] For example, the voltage of four power transformers (hereafter referred to as TRs) in the building's power receiving and transforming equipment, TR capacity, thermal relay, circuit current, equipment capacity, etc., and the program for automatic shutdown of the boiling point temperature of the distribution board, circuits, terminal electrical equipment, and load equipment of the system based on the detected temperature are as shown in the figure.

[0301] Regardless of the above, the DESCON Safety Control System will consider the load capacity of the system's low-voltage distribution board, distribution board, circuits, etc. in the design drawings for the surrounding environment of the power receiving and transforming equipment, lighting and power TR, or the capacity KVA of the TR, and the additional capacity due to the usage status of the system's electrical equipment, mechanical equipment, terminal load equipment, etc., and for example, as shown in 7-3, if the No. 1 power TR is 500KVA, the maximum current is 1718A, or exceeds 100%, and if the outside air temperature of the surrounding environment of the TR is abnormally high, for example, the boiling point temperature is 2 The boiling point warning temperature of the insulating oil is set to, for example, 290°C to 340°C, and the TR may be (1) the boiling point temperature of the insulating oil, 290°C, or (2) a preset boiling point coefficient of 0.7...0.98, etc. = (set 290°C x arbitrary coefficient 0.7...0.98) = (3) the boiling point warning temperature range of the insulating oil, 203.0°C to 261°C, etc., and (4) the boiling point warning temperature of 203.0°C, for example, is set arbitrarily as the boiling point warning temperature. For example, (5) if a boiling point warning detection temperature of 203 to 261°C is detected, an alert will be sent to the PC, tablet, smartphone, etc. of the relevant person as a boiling point warning temperature, with relevant information such as the customer name, building name, facility name, location, TR light, power type, capacity, system end electrical equipment, and load equipment name as an audio, numerical value, image, etc. alert, and the alert can be sent multiple times until the relevant person confirms that it has been sent, preventing electrical burnout and fire accidents.

[0302] The DESCON Safety Control System, for example, can set the boiling point temperature range of insulating oil (1), which is usually between 290°C and 340°C, arbitrarily, for example, (2) an arbitrary boiling point cutoff coefficient of 0.75 to 0.9, (3) a boiling point temperature of 290°C, (4) a boiling point cutoff coefficient of 0.75, (5) a boiling point cutoff temperature of 217°C, and (6) a boiling point temperature of 290°C, (7) an automatic cutoff coefficient of 0.9, (8) a boiling point cutoff temperature of 261°C, and (9) a boiling point temperature of 340°C, (10) an automatic cutoff coefficient of 0. In 75, (11) when a boiling point cutoff temperature of 306°C is detected, (12) the circuits of the relevant panel, etc., of the system distribution panel control panel, etc. of the relevant low-voltage distribution panel, terminal load electrical equipment, terminal load equipment, etc., are selected in advance to automatically cut off the power supply due to temperature, (13) the priority order of the distribution panel, control panel, circuit, terminal load electrical equipment, terminal load equipment, etc., for automatic cutoff is determined, and (14) until the detected temperature reaches a temperature arbitrarily determined in advance, (15) a means for automatically cutting off the distribution panel, control panel, circuit, etc., terminal load electrical equipment, terminal load equipment, etc., can be provided.

[0303] The DESCON safety control system is an automatic shut-off program with a preset automatic shut-off coefficient of 0.75 at the boiling point temperature of the power TR, for example, 290°C.

[0304] The DESCON safety control system has the following characteristics: (1) TR capacity is 500KVA, (2) maximum current is 1718A, (3) alarm current is 1350A, (4) load equipment capacity is 393kw, (5) load factor is 79%, (6) main distribution board capacity is 145KVA, additional distribution board capacity is 55KVA, total 200KVA, (7) for example, TR No. 1 of the relevant TR has an arbitrary boiling point temperature of 290°C, (8) arbitrary boiling point caution coefficient is 0.7, (9) ) Boiling point caution temperature is 203°C, (10) boiling point cutoff coefficient is 0.75, (11) boiling point cutoff temperature is 218°C, (12) the detected temperature at 17:00 is 275.0°C, (13) automatic cutoff temperature coefficient = (detected temperature 275°C / automatic cutoff temperature 218°C) = 1.26, (14) the automatic cutoff coefficient is (1.26 - 1.0) = 0.26, (15) automatic cutoff capacity = (converted to TR200KVA x cutoff coefficient 0.26) = 132.2KVA, (16) automatic cutoff capacity is 134.8KVA, (17) current cutoff coefficient is 0.98, (18) temperature after cutoff = (detected temperature 275°C x current cutoff coefficient 0.97) = 213°C.

[0305] However, the DESCON safety control system can be configured to have a determination means that if the detected temperature of the relevant TR, 275.0°C, falls to the arbitrarily set temperature of 203°C, for example, by shutting off circuit (3), the automatic shutoff will stop in circuit (2) of the additional distribution board, and circuit (4) will operate normally.

[0306] The DESCON Safety Control System creates a database of the relationship between current value and operating time for the safety protection of terminal load equipment and electrical equipment, and (1) when automatic shutdown is performed as described above, (1) an alert is sent to the relevant person's PC, tablet, smartphone, etc., with the relevant information, such as the customer name, building name, facility name, location, TR light, power type, capacity, system end, etc., and an alert is sent in real time using audio, images, and numbers, and the breakers of the relevant equipment, such as distribution boards, distribution boards, control panels, main lines, and circuits, are connected to remote devices for each system, etc., via a cloud server, LAN, etc., through an emergency response protection program, and the remote devices, such as the relevant distribution boards, distribution boards, control panels, etc., send a stop signal to the protection stop device, safely and reliably stopping the equipment and also having the function of confirming the stop signal.

[0307] The DESCON safety control system creates a database of the relationship between current value and operating time for the safety protection of terminal load equipment and electrical equipment, and (1) when a timed shutdown is performed as described above, (1) an alert is sent in real time to the relevant person's PC, tablet, smartphone, etc., with voice, numerical value, image, etc., of the relevant information, such as the customer name, building name, facility name, location, TR light, power type, capacity, system terminal electrical equipment, load equipment name, etc., and the breakers of the relevant equipment, such as distribution boards, distribution boards, control panels, main lines, circuits, etc., are controlled by remote devices for each system, etc., via a cloud server, LAN, etc., by an emergency response protection program, and the remote devices of the relevant distribution boards, distribution boards, control panels, etc. send a stop signal to the protection stop device, safely and reliably stopping the function and also confirming the stop signal.

[0308] For example, the building's power receiving and transforming equipment automatically shuts off the voltage, TR capacity, thermal relay, circuit current, equipment capacity, etc. of three lighting transformers (hereinafter referred to as TR), as well as the boiling point temperature of the distribution board, circuits, terminal electrical equipment, and load equipment of the system based on the detected temperature.

[0309] For example, of the three lighting transformers (hereinafter referred to as TRs) in a building's power receiving and transforming equipment, the capacity of power TR No. 1, the thermal relay, circuit current, equipment capacity, etc., as well as the detection temperature and cut-off coefficient of the main distribution board are as follows.

[0310] Regardless of the above, the DESCON Safety Control System will consider the load capacity of the system's low-voltage distribution board, distribution board, circuits, etc. in the design drawings for the surrounding environment of the power receiving and transforming equipment, lighting and power TR, or the capacity KVA of the TR, and the additional capacity depending on the usage status of the system's electrical equipment, mechanical equipment, terminal load equipment, etc. For example, as shown in 8, if the No. 1 lighting TR is 200KVA, the maximum current is 952A, and the load is 100% or more, or if the outside temperature of the surrounding environment of the TR is abnormally high, for example, the boiling point temperature is 290 The boiling point warning temperature of the insulating oil is set to, for example, 290°C to 340°C in advance as an arbitrary boiling point warning temperature of the insulating oil, and the TR may be (1) the boiling point temperature of the insulating oil, 290°C, or (2) an arbitrarily set boiling point coefficient, such as 0.7 to 0.98, of the TR = (set 290°C x arbitrary coefficient 0.7 to 0.98) = (3) the boiling point warning temperature range of the insulating oil, such as 203.0°C to 261°C, and (4) the boiling point warning temperature, 203.0°C, is arbitrarily set as the boiling point warning temperature, for example. For example, (5) if a boiling point warning detection temperature of 203 to 261°C is detected, an alert will be sent to the PC, tablet, smartphone, etc. of the relevant person as a boiling point warning temperature, with relevant information such as the customer name, building name, facility name, location, TR light, power type, capacity, system end electrical equipment, and load equipment name as an audio, numerical value, image, etc. alert, and the alert can be sent multiple times until the relevant person confirms that it has been sent, preventing electrical burnout and fire accidents.

[0311] However, the DESCON safety control system can be configured to have a determination means that if the detected temperature of the relevant TR, 275.0°C, for example, is cut off by cutting off circuit (3) and the temperature drops to the maximum allowable temperature of 105°C or to an arbitrary set temperature of 203°C, the automatic cutoff will stop in circuit (2) of the additional distribution board, and circuit (4) will operate normally.

[0312] The DESCON Safety Control System creates a database of the relationship between current value and operating time for the safety protection of terminal load equipment and electrical equipment, and (1) when a timed shutdown is performed as described above, (1) an alert is sent to the relevant person's PC, tablet, smartphone, etc., with the relevant information, such as the customer name, building name, facility name, location, TR light, power type, capacity, system end, etc., and an alert is sent in real time using audio, images, and numbers, and the breakers of the relevant equipment, such as distribution boards, distribution boards, control panels, main lines, and circuits, are connected to remote devices for each system, etc., via a cloud server, LAN, etc., by an emergency response protection program, and the remote devices of the relevant distribution boards, distribution boards, control panels, etc. send a stop signal to the protection stop device, so that the remote devices can safely and reliably stop the equipment, and also have a control means for confirming the stop signal.

[0313] The DESCON safety control system creates a database of the relationship between current value and operating time for the safety protection of terminal load equipment and electrical equipment, and (1) when a timed shutdown is performed as described above, (1) an alert is sent to the relevant person's PC, tablet, smartphone, etc. in real time with audio, numerical values, images, etc., including the relevant customer name, building name, facility name, location, TR light, power type, capacity, system terminal electrical equipment, load equipment name, etc., and the breakers of the relevant equipment, such as distribution boards, distribution boards, control panels, main lines, circuits, etc., are controlled by remote devices for each system, etc., via a cloud server, LAN, etc., through an emergency response protection program, so that the remote devices of the relevant distribution boards, distribution boards, control panels, etc. send a stop signal to the protection stop device, safely and reliably stopping the function and also having a control means for confirming the stop signal.

[0314] The DESCON Safety Control System is suitable for a wide range of buildings and facilities, including complex buildings, skyscrapers, underground shopping malls, warehouses, logistics centers, factories, etc.; commercial facilities, assembly halls, theaters, hospitals, schools, hotels, offices, apartment complexes, laboratories, data centers, event halls, etc.; outdoor facilities such as power plants, substations, water purification plants, etc.; transportation facilities such as trains and ships; and large buildings and facilities, including (1) fire prevention facilities, where the smoke detectors, heat detectors, flame detectors, etc. of fire alarms on the disaster prevention panel detect, for example, the heat, smoke, etc. of an early stage fire. and (2) automatically shuts off the circuits of the low-voltage distribution board, distribution board, control panel, etc. of the low-voltage lighting and power of the substation equipment, and the terminal electrical equipment, terminal load equipment, etc.; (3) also detects the relevant area, such as the building, floor, area, room, etc., detected by the fire alarm, and (4) notifies of an electrical fire accident, such as a short circuit, spark, tracking, etc. in the circuits, main lines, wiring, etc. of the low-voltage distribution board, distribution board, control panel, etc., and the terminal electrical equipment, terminal load equipment, etc.
