Description

Power quality improvement and smart electric fire detection system and method

The present invention relates to a system and method for improving power quality and detecting smart electrical fires, and more particularly, to a power distribution board, a power distribution board, an inverter, a motor control panel, a solar power connection board, an electrical equipment connection part of an ESS, or ultraviolet rays emitted from the inside of an electrical equipment It relates to a system and method for improving power quality and smart electrical fire detection that enable rapid discharge of internal heat while expanding the detection range of visible and infrared rays.

In general, when a fire occurs in distribution panels, switchboards, inverters, motor control panels, solar junction panels, electrical equipment connections to ESS or electrical equipment, the flames that appear during the combustion process radiate energy in a wide spectrum band and emit visible light (0.4㎛). In addition to ~0.8㎛), it emits infrared rays with a wavelength longer than 0.8㎛ and ultraviolet rays with a wavelength shorter than 0.4㎛, which are invisible to the naked eye.

As described above, conventional sensors for monitoring infrared rays, visible rays, and ultraviolet rays of a flame generated during a fire have a basic angle of view of the lens of 45 ° for the UV detector, 80 ° for the infrared detector, and 110 ° for the visible ray detector. is °

However, the above-mentioned conventional sensor lenses do not have a large basic angle of view, so they can continuously monitor electrical equipment connections or electrical equipment and other blind spots in distribution boards, switchboards, inverters, motor control panels, solar junction panels, and ESS where the risk of fire is expected In order to do this, there is a problem in that a considerable number of sensors must be installed, and the cost required for installing a plurality of sensors also increases considerably.

In addition, conventional sensor lenses generally move only in the horizontal direction, so that the monitoring range is not wide, so as mentioned above, there is a problem that a plurality of sensors must be installed.

In addition, among conventional fire detection sensors, since the infrared thermal image detection unit is exposed, dust or foreign substances are piled up and it is inconvenient to periodically remove the dust or foreign substances accumulated on the lens.

In addition, the power factor control of a switchboard, a motor control panel, or a device that performs power factor control for a plurality of loads performs separate power factor control for various loads (eg, transformers, motors, home appliances, lighting products, etc.), As the power factor is controlled for each load, a large number of capacitors are used.

Here, the power factor refers to the ratio of active power to apparent power. That is, it is the ratio of the power actually doing work among the total input power. This power factor is used as a major control factor in places requiring power control or technology for preventing waste of power consumption.

Therefore, power factor control increases the power factor of a load by the target power factor, and the power factor control method mainly used in power facilities increases the power factor by lowering the apparent power. Apparent power is related to reactive power, and the larger the reactive power, the higher the apparent power, and the smaller the reactive power, the lower the apparent power. Therefore, the power factor is compensated by lowering the apparent power by lowering the reactive power.

For this reason, the conventional switchgear has a problem of high installation cost due to the use of many capacitors, and as separate power factor control is required for each load, a separate power factor controller must be installed, and the number of parts increases and power factor control The design for this was a complicated problem.

The present invention has been made to solve the above problems, and power factor control is possible through the detection of voltage and current in distribution boards, switchboards, inverters, motor control boards, solar junction panels, electrical equipment connection parts of ESS or electrical equipment. In addition to improving power quality, a system and method for improving power quality and expanding the monitoring range by using a lens for monitoring infrared, ultraviolet, and visible rays of flame generated in the event of a fire as a light-receiving lens are developed. Its purpose is to provide

Based on the principle that there is, it should be interpreted as meaning and concept consistent with the technical spirit of the present invention.

Therefore, since the embodiments described in this specification and the configurations shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, they can be substituted at the time of this application It should be understood that there may be many equivalents and variations.

1 is a perspective view schematically showing a power quality improvement and smart electrical fire detection system according to the present invention, and FIG. 2 is a configuration diagram showing the power quality improvement and smart electrical fire detection system of FIG. 1 in more detail.

The power quality improvement and smart electrical fire detection system 1 according to the present invention is composed of a power factor adjustment and electrical fire detection unit 100 and a body unit 200, as shown in FIGS. 1 and 2 .

Here, the power factor adjustment and electric fire detection unit 100 includes a first detection module 110, a first detection module driver 120, a second detection module 130, a second detection module driver 140, and a signal It includes an amplification unit 150.

The first sensing module 110 includes an infrared sensing unit 111, an ultraviolet sensing unit 112, a visible ray sensing unit 113, a gas sensing unit 114, and a power factor adjusting unit 115 formed in the front in a cylindrical columnar shape. ).

In general, light has unique properties such as straightness, dispersion, refraction, scattering, synthesis, interference, diffraction, and polarization. And the speed of light in a material depends on the wavelength of the medium, and the refractive index also changes according to the wavelength. Qualitative dispersion occurs in regions away from the natural spectral lines or bands of the medium, but anomalous dispersion occurs in the vicinity of the natural spectrum.

The wavelength band of this light consists of gamma rays, X-ray rays, ultraviolet rays, infrared rays, visible rays, and the like. The mechanically generated arc flash is composed of the same components as light, and the same wavelength band as light.

Therefore, in order to accurately detect the arc flash, it is necessary to detect various wavelength bands. Light has properties of straightness and dispersion, and in order to use this effectively, a light-receiving lens 101 is used in the present invention.

The infrared sensor 111 measures the sensitivity of the flame ignited inside the switchgear to an infrared wavelength corresponding to 4.3 μm to 4.4 μm, and preferably detects the flame by detecting the 4.3 μm wavelength.

The infrared sensor 111 generates carbon monoxide and carbon dioxide from a flame generated from hydrocarbons, and the infrared absorption wavelength range of carbon monoxide and carbon dioxide is composed of a narrow band filter (NBF) filter chip between 4.0 μm and 4.8 μm. detect

On the other hand, the wavelength of carbon dioxide generated during combustion exists in the infrared region of approximately 4.3 μm.

This is a unique spectral characteristic of carbon dioxide to be heated by the combustion heat of an object, and the infrared absorption wavelength band is 4.0 μm to 4.8 μm.

The infrared detector 111 uses an infrared band pass filter of 4.3 to 4.4 μm to detect the resonance radiation.

The UV sensor 112 is concentrated in a very short wavelength band in the corona discharge range of 200 to 400 nm, and measures and detects a band of 380 to 390 nm with relatively less noise than other existing wavelengths.

The visible light detector 113 detects sensitivity to visible light wavelengths of 400 nm to 780 nm, and more precisely, peaks at one to three locations of 430 nm to 470 nm, 530 nm to 570 nm, or 630 nm to 670 nm. (peak) is detected to measure visible light.

The gas sensor 114 corresponds to a ceramic semiconductor gas sensor using a reaction between a solid surface and a gas, and detects CO by an adsorption reaction according to an operating temperature of the solid surface.

The power factor adjusting unit 115 adjusts the power factor through voltage and current for electric equipment corresponding to a distribution board, a switchboard, an inverter, a motor control board, a solar connection board, and an ESS.

At this time, the power factor adjusting unit 115 calculates the optimal reactive power by detecting the voltage and current of the load side, learns the capacitor's capacity for the calculated reactive power, and invalidates it based on the learned capacitor's capacity. The power factor can be automatically compensated by controlling the power.

Meanwhile, the power factor adjusting unit 115 detects not only voltage and current, but also active power and reactive power, and outputs a power factor control signal according to the capacity of the capacitor when the voltage and current are greater than or equal to a set value.

In addition, the power factor adjusting unit 115 may collectively control the power factor of at least one load requiring power factor control with respect to a plurality of loads. On the other hand, the power factor control determines how much the power factor is to be increased with respect to the target load and performs the power factor control, that is, the power factor is controlled by determining the amount of power factor adjustment.

Therefore, the power factor adjusting unit 115 determines whether there is a target load among a plurality of loads, and if there is a target load, determines the power factor adjustment amount for each target load.

Meanwhile, the power factor adjusting unit 115 uses the minimum number of power factor adjusting elements (eg, capacitors or reactors) capable of controlling the power factor for each load. In this case, the plurality of power factor adjusting elements may have the same capacitance (that is, the same power factor correction amount) or may have different capacitances, and may be configured by mixing the same capacitance and different capacitances.

In this environment, the power factor adjusting unit 115 inputs (connects) at least one power factor adjusting device corresponding to the power factor adjusting amount among a plurality of power factor adjusting devices to one target load to perform power factor control. However, when there are two target loads, the second target load controls the power factor by inserting (connecting) at least one power factor adjustment element corresponding to the amount of power factor adjustment among the remaining power factor adjustment elements except for the power factor adjustment element inserted into the first target load. do. Of course, if there are three or more target loads, the third and fourth power factor adjustment devices, except for the power factor adjustment elements inserted into the previous target load, are used for power factor adjustment.

For this reason, when a target load is found, the power factor adjusting unit 115 determines which power factor adjustment element is to be input to which target load, and performs selective control of inputting a capacitor according to the determination result to the corresponding load. Here, the selective control is a control operation that determines which load is connected (injected) to one power factor adjustment device.

Meanwhile, when there are a plurality of target loads, the power factor adjusting unit 115 randomly determines priorities to perform power factor control or performs power factor control according to the set priorities. Of course, the higher the priority, the faster the power factor control sequence.

The first sensing module driver 120 includes a first starting point detector 121 and a first stepper motor 122 and drives the first sensing module 110 to rotate.

Since it is difficult for the first stepper motor 122 to simply calculate the starting point, the first starting point detector 121 inserts a circular magnet into the rotating body and arranges a magnetization sensor capable of recognizing the circular magnet at the starting point to accurately determine the starting point. By enabling the detection of the starting point, the first sensing module driver 120 is rotated to the original position even after the corresponding first stepper motor 122 rotates to the starting point.

The first stepper motor 122 is connected to the first sensing module 110 and is protected by the suction prevention cover 133 as shown in FIG. 3 by rotating the first sensing module 110. The second sensing module 130 in the rear is disposed forward.

At this time, the infrared detection unit 111, the ultraviolet detection unit 112, and the visible light detection unit 113 located in the front and measuring the type and intensity of light are located behind the suction prevention cover 133 in a dark room. Calibration or failure determination may be made in , and when a failure occurs, the fact of failure may be notified through the alarm unit 208 or the display unit 209 .

Meanwhile, the second sensing module 130 and the first sensing module 110 are integrally formed behind the corresponding first sensing module 110 .

In particular, the second sensing module 130 includes a second non-contact temperature sensor 131 and an infrared thermal image sensing unit 132 .

The second non-contact temperature sensor 131 detects a temperature change with a negative temperature coefficient (NTC) having a property that a resistance value decreases as the temperature rises and a negative temperature coefficient of resistance.

Meanwhile, the outside of the negative temperature coefficient is insulated with epoxy to prevent parts from being damaged by electro static discharge (ESD).

That is, the second non-contact temperature sensor 131 detects the ambient temperature by applying a negative temperature coefficient method that measures a temperature change using the property that electrical resistance rapidly drops when the voltage rises above a certain level.

At this time, the temperature value measured by the second non-contact type temperature sensor 131 is compared with the temperature value measured by the infrared thermal image sensor 132 protected by the adsorption prevention cover 133, and the corresponding infrared deterioration It is preferable that it can be used as a reference value for determining whether or not the inlaid sensor 132 has a failure.

Also, at this time, when a failure occurs in the infrared thermal image sensing unit 132, the failure sensor may be notified through the alarm unit 208 or the display unit 209.

The infrared thermal image sensor 132 measures the temperature of the surface by measuring the amount of infrared rays emitted (radiated) from the object.

That is, the infrared thermal image sensor 132 measures infrared radiation heat emitted from an object and calculates a temperature based on the measured infrared radiation heat value.

On the other hand, when an electric fire occurs, an infrared detector 111, an ultraviolet detector 112, a visible ray detector 113, and a gas detector formed in front of the first detection module 200 due to smoke generated simultaneously The accuracy of the measured value of (114) is reduced.

At this time, the second non-contact temperature sensor 131 of the second sensing module 130 formed at the rear of the first sensing module 110 and the infrared thermal image sensing unit 132 are positioned forward to detect heat with infrared rays, By detecting the temperature, it determines the occurrence of fire with certainty.

As described above, the infrared thermal image sensor 132 can perform non-contact measurement, quickly and accurately check the surface temperature to diagnose deterioration, and can measure without directly touching the measurement target, so the safety of the operator can be guaranteed. In addition, damage to the device itself can be minimized.

In particular, the infrared thermal image sensor 132 can safely measure a high-temperature measurement target, perform measurement without damaging or destroying the measurement target, and can perform measurement without interfering with the process. Because measurements can be performed without stopping facilities on site, unnecessary costs due to facility shutdowns can be prevented.

However, since the infrared thermal image sensing unit 132 cannot transmit through transparent glass and acrylic, a lens such as transparent glass or acrylic cannot be formed on the front side, so the penetration probability of foreign substances is high. It is located at the rear due to the rotation of the first sensing module 110 and is protected by the dust adsorption prevention cover 133 .

The second sensing module driver 140 includes a second starting point detector 141 and a second stepper motor 142 to drive the second sensing module 130 to rotate vertically.

The second starting point detection unit 141 inserts a circular magnet into the rotating body because it is difficult for the second stepper motor 142 to simply calculate the starting point, and arranges a magnetization sensor capable of recognizing the circular magnet at the starting point to accurately determine the starting point. By enabling the detection of the starting point, the second sensing module driver 140 is rotated to the original position even after the corresponding second stepper motor 142 rotates.

The second stepper motor 142 is connected to the second sensing module 130 to rotate the corresponding second sensing module 130 so as to move up and down.

The signal amplification unit 150 is equipped with an amplification circuit so as to receive signals detected by the sensors of the first detection module 110 and analyze them easily in the main control unit 201 of the main body unit 200 if necessary. By amplifying it, an ideal value without abnormal oscillation and ripple induced by an external frequency is generated and the detection ability is improved.

The main body unit 200 that receives the signal detected by the power factor adjustment and electrical fire detection unit 100 and finally determines whether or not there is an electrical fire is a main control unit 201, an inspection request indicator light ( 202), aerosol driving unit 203, first contact type temperature sensor 204, communication unit 205, electric shock voltage detection unit 206, emergency power unit 207, alarm unit 208, display unit 209, first non-contact type A temperature sensor 210, a control unit 211, a program writing terminal 212, a laser irradiation unit 213, a hot air discharge unit 214, and a second contact temperature sensor 215, including the power factor adjustment and electric fire The parameter detected by the sensing unit 100 is received, an Electric Fire Risk Index (EFRI) is calculated using the spread engine, and the first sensing module 110 and After determining the occurrence of a fire with different reference thresholds according to temperature values by controlling the second sensing module 130, the internal situation may be notified with different messages, sounds, and lights.

The main control unit 201 analyzes analog information signals detected by the sensors of the first sensing module 110 to convert them into digital signals, that is, digitally process the signals.

The inspection request indicator light 202 is an absurd value as a result of receiving and analyzing the value detected by the sensing units of the first sensing module 110 by the main control unit 201. Indicates inspection requests with colors or different blinking patterns.

The aerosol driving unit 203 can be used as an output unit outputting DC 12V 100mA or an AUX contact unit when determining an electrical fire.

The first contact-type temperature sensor 204 measures the temperature of one or more busbars in the switchboard in a contact-type manner, and when a temperature higher than a threshold value is measured, the deterioration of the corresponding busbar is displayed in the alarm unit 208 or the display unit 209. By generating an early notification through this, deterioration can be prevented.

For example, when the busbar connection temperature is 50 ° C, the temperature rise limit is 25 ° C, and the ambient temperature is 40 ° C, the maximum allowable temperature = temperature rise limit (25 ° C) + ambient temperature (40 ° C + 40 = 65 ° C).

The first contact temperature sensor 204 determines whether the internal temperature is suitable through (busbar temperature - ambient temperature) × coefficient (1.1 to 1.25) < temperature rise limit (25 ℃), and through the above calculation formula, 12.5 ℃ Since it is <25℃, it is judged that the internal temperature is suitable.

That is, the first contact temperature sensor 160 compares the temperature (bus duct temperature-ambient temperature) × coefficient (1.1 to 1.25) < temperature rise limit (25 ° C) through the calculation formula to obtain 5 degrees higher than the ideal temperature standard of 65 degrees. The risk of deterioration of the bus duct is detected at an early stage by managing the

The communication unit 205 is equipped with one or several communication modules among IC2C, RS485, MOD-BUS, Wife, Can, and Bluetooth, and the electrical fire detection device (1) of the active electrical fire detection and emergency guidance direction indicating system according to the present invention. ) transmits the sensing information sensed by the first sensing module 110 or the second sensing module 130 to the corresponding external server while communicating with an external server or a smart terminal of a manager who manages the switchgear 2. Informs the inner state of the switchgear (2).

The electric shock voltage detection unit 206 measures the voltage between the N phase of the MCCB and the enclosure to check the electric shock voltage of the human body in real time.

In particular, the electric shock voltage detection unit 206 may detect and display less than 10V as normal, 10V or more and less than 20V as a caution, 20V or more and less than 30V as an emergency, and 30V or more as an emergency, or inform the communication unit 205. .

It is difficult to uniformly determine the limits of human response and death due to electric shock due to the nature of human experiments and the difficulty in verifying any test results, human diversity, and situational variables at the time of a disaster. In case of electric shock, the degree of danger is almost determined by the magnitude of the current, the duration of the current, the path of the current, and the type of power source.

The effects of electric shock on the human body can be divided into two major categories. First, electrical signals stimulate nerves and muscles, impeding normal functions, causing respiratory arrest or ventricular fibrillation, and second, electrical energy destroys living tissue. , damage, and other structural damage.

The emergency power supply unit 207 is a lithium polymer battery, and is used as a power source for an electric fire monitoring and blocking device using a light-receiving lens when the power is cut off during normal charging and an electric fire.

The warning unit 208 outputs a value detected by the sensing units included in the first sensing module 210 or the second sensing module 130 as a sound, or outputs a warning message or sound in case of a dangerous situation.

The display unit 209 displays values detected by the infrared sensor 111, the ultraviolet sensor 112, the visible light sensor 113, the gas sensor 114, and the infrared thermal image sensor 132. Alternatively, if the risk of fire occurrence is expected by the detected value, it may be displayed.

In particular, in relation to the infrared thermal image detection unit 132, the display unit 209 receives and displays the image detected by the infrared thermal image detection unit 132, so that a manager can view the infrared thermal image detection unit through the display unit 209. (132) allows you to check the detected image.

Meanwhile, the display unit 209 displays the thermal image detected by the thermal image detection unit 132 and at the same time, like a black box, displays detailed information such as shooting time, vertical and horizontal shooting angles, etc. so that the manager can accurately determine the location of the fire. Identify and enable tracking.

Like the second non-contact temperature sensor 131, the first non-contact temperature sensor 210 detects the internal temperature of an electrical installation such as a switchboard by means of a mechanism in which a resistance value decreases as the temperature rises.

First, the body unit 200 performs a step of receiving values detected by the sensing units included in the first sensing module 110 and the second sensing module 130 of the power factor adjustment and electrical fire sensing unit 100. Do (S100).

That is, the main body 200 measures the infrared ray detector 111, the ultraviolet ray detector 112, the visible ray detector 113, and the gas detector 114 of the first detection module 110. It receives infrared, ultraviolet, visible light, and CO.

Thereafter, the main control unit 201 compares the value received in step S100 with the threshold value of each parameter stored in the database unit (S200).

First, the main control unit 201 compares the ultraviolet rays sensed by the ultraviolet sensor 112 with a threshold value (S210).

In addition, the main control unit 201 compares the flame value with a threshold value by using the infrared wavelength sensed by the infrared sensor 111 as a flame value (S220).

In addition, the main control unit 201 compares whether the visible ray value detected by the visible ray detection unit 113 is greater than a threshold value (S230).

The main control unit 201 receives the value detected from the sensing units included in the first sensing module 200 when the measured value is not greater than the threshold value in any one of the steps S210 to S230. Repeat the steps.

On the other hand, if the detection value is greater than the threshold value in any one of the steps S210 to S230, the main control unit 201 directly controls the CO detected by the gas detection unit 114 and the threshold value. Performs a step of comparing (S300).

In step S300, if the CO value is not greater than the threshold value, the step S100 is repeatedly performed, and if the CO value is greater than the threshold value, the main control unit 201 determines the electric fire risk index (EFRI) A step of calculating is performed using a fuzzy engine (S400).

The main control unit 201 compares the electrical fire risk index (EFRI) calculated in step S400 with a reference threshold value, and displays a warning in a different form according to the comparison result (S500).

That is, the main control unit 201 outputs a warning message, a warning light, and a warning sound in a different form through the inspection request indicator light 202, the display unit 209, or the warning unit 208 according to the comparison result in step S500. do.

The step S500 will be described in more detail with reference to FIG. 10 .

The main control unit 201 performs a step of determining whether the electric fire risk index (EFRI) is equal to or greater than a reference threshold value of 70 (S511).

A step of controlling the first sensing module driver 120 is performed (S512).

As the first sensing module 200 rotates, the resistance value of the infrared thermal image sensing unit 132 disposed forward decreases as the temperature rises. When the infrared temperature value is measured, the main controller 201 detects the infrared A step of receiving a temperature value is performed (S513).

The main controller 201 compares the infrared temperature value received in step S513 with a temperature value threshold (S514).

The hot air discharge unit 214 is composed of a vortex fan, and sucks and discharges dust, moisture, carbon monoxide, sulfur dioxide, formaldehyde, volatile organic compounds, etc. heavier than air by wind generated by rotation of the fan.

The second contact temperature sensor 215 measures one or more temperatures in the electrical equipment, and when a temperature higher than a threshold value is measured, the corresponding system deterioration is notified early through the alarm unit 208 or the display unit 209. generated to prevent deterioration.

That is, FIG. 11 is a configuration diagram showing the hot air discharge unit of FIG. 2 , and FIG. 12 is a front view, a side view, and a rear view of the swirl fan shown in FIG. 11 .

As shown in FIGS. 11 and 12, the hot air discharge unit 214 is coupled to a driving fan 214a having a plurality of rotary blades attached in an oblique direction to the central axis, and to the central axis of the driving fan 214a. A vortex fan 214c composed of an annular disc and a plurality of vortex blades arranged and fixed in the radial direction along the edge of the annular disc connected to each other, and the drive fan 214a and the vortex fan 214c On the connecting shaft It is connected by means of a bearing, supports the connecting shaft while forming a suction port of a certain size, and has a bracket (214b) attached to the end of the suction port of an exhaust pipe (not shown).

Here, the bracket 214b is connected to the connecting shaft between the drive fan 214a and the vortex fan 214c by means of a bearing so that the vortex fan 214c is rotated by the rotational force of the drive fan 214a, and the end It supports the connecting shaft while forming a suction port of a certain size in the pipe, and is fixed to the end of the suction port of the exhaust pipe by fitting or bolts.

A circular belt member (C) in which a plurality of pins protrude outward in the radial direction, and a plurality of vortex generating connecting rods (D) extending radially from the outer circumferential surface of the rotating plate (B) to the inner circumferential surface of the circular belt member (C) ), including

The hot air discharge unit 214 configured as described above is configured such that the vortex fan 214c is rotated by the rotational force of the driving fan 214a, and discharges pollutants having a higher specific gravity than air including hot air.

Since the hot air discharge unit 214 has a collecting capacity 3 to 6 times that of a general exhaust fan, when installed in a distribution board including a switchboard, it can collect and discharge pollutants inside more quickly, as well as a general exhaust plate. Compared to that, electricity consumption can be reduced.

On the other hand, when the heat exhaust unit 214 operates in the event of a fire, it is necessary to control it because there is a high risk of fire spreading.

That is, as shown in FIG. 13 , temperature sensing values of the first sensing module 110 and the second sensing module 130 are received (S100).

Subsequently, the received temperature sensing value is compared with a threshold value (S200).

At this time, the comparison between the temperature sensing value and the threshold value repeatedly receives and wakes up the temperature sensing value of step S100 in the sleep mode state when an abnormal state is determined to calculate an electric fire occurrence temperature index.

That is, when the temperature sensing value is higher than the threshold value, the temperature sensing value is received again and the steps of S210, S220, and S230 are repeatedly performed, and when the temperature sensing value is lower than the threshold value, the detected temperature is fed back to step S100. The sensing value is received and the threshold value and steps of S210, S220, and S230 are repeatedly performed.

Subsequently, a temperature index of electrical fire occurrence is calculated by comparing the temperature sensing value with the threshold value (S300).

At this time, only when the electric fire occurrence temperature index is determined to be safe, the hot air discharge unit 214 is driven to forcibly discharge the heat inside.

Meanwhile, the calculation of the electric fire occurrence temperature index is continuously performed, and the operation of the hot air discharge unit 214 is stopped when the electric fire occurrence temperature index is calculated even when the hot air is discharged, and the electric fire occurrence temperature index does not decrease.

In addition, when the electrical fire occurrence temperature index is calculated as a FULL band and the electrical fire occurrence temperature index maintains an upward curve regardless of the discrimination criteria, an early warning is generated through the alarm unit 208 to inform the manager of the electrical fire risk In addition, it is possible to prevent danger from fire by performing control such as turning off the circuit breaker through self-determination through manager option setting.

Therefore, by discharging internal heat more quickly through the hot air discharge unit 214, deterioration of the switchgear or distribution board can be prevented in advance, and overall life span can be extended and power quality can be improved.
