Description

Power quality improvement and smart hot exhaust system {Power quality improvement and electrical accident detection device}

The present invention relates to power quality improvement and a smart hot air discharge system. In particular, it improves power quality by enabling power factor control through detection of voltage and current, as well as distribution boards, distribution boards, inverters, motor control panels, solar power connection panels, By expanding the detection area of ultraviolet rays, visible rays, and infrared rays emitted from the ESS's electrical equipment connections and electrical equipment, it detects electrical accidents and improves power quality and smart heat exhaust system to quickly discharge internal heat. It's about.

In general, the temperature environment is very important in power facilities and industrial facilities such as switchboards (or switchboards), transformer facilities, transmission facilities, motor control panels, and distribution boards.

Most high-voltage breakers and low-voltage breakers are installed in the switchboard to protect load devices and circuits from overcurrent and abnormal current. These breakers are electrically connected using bus-bars and bus clips for mutual connection and separation, and bus-bars, which are conductive metal materials, are applied in consideration of power capacity.

Meanwhile, high-voltage and high-capacity busbars and bus clips generate heat due to Joule heat when energized, and connection resistance may increase as they become loose due to repeated connection and disconnection.

In general, heat generation and loss in power equipment (e.g., transformers) are caused by an increase in neutral current, an increase in neutral temperature, and an increase in ground voltage due to zero harmonic currents generated from numerous single-phase (nonlinear) loads at the end of power equipment. As this occurred, there was a risk of power loss, deterioration, and fire.

In addition, changes in connection resistance occur due to abnormalities such as foreign matter, oxidation, and corrosion on the connection surface of the power device, which may result in damage to the power device due to excessive heat generation. Sometimes it can lead to fire, etc., resulting in significant property damage.

And if power is cut off as a corresponding measure, large economic losses will occur due to the interruption of operating facilities receiving power, and unstable power supply may ultimately cause safety accidents.

In this way, in conventional switchboards, the subsequent losses or consequences due to a single small problem are very large and excessive, so it is necessary to monitor the switchboard in real time and prevent problems before they occur.

In addition, the power factor control of a switchgear, a motor control panel, or a device that performs power factor control for multiple loads performs separate power factor control for each load (e.g., transformers, motors, home appliances, lighting products, etc.). A large number of condensers are used to control the power factor for each load.

Here, power factor refers to the ratio of active power to apparent power. In other words, it is the ratio of the power that actually does work out of the total input power. This power factor is used as a key control factor in places that require power control or technology to prevent power consumption waste.

Therefore, power factor control increases the power factor of the 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. 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 reactive power and lowering the apparent power.

For this reason, the conventional switchgear has the problem of high installation costs due to the use of many condensers, and as power factor control must be performed separately for each load, a separate power factor controller must be installed, and by installing it for each load, the number of parts increases and power factor control is required. There were complex design problems for .

The present invention was devised to solve the above problems. It improves power quality by enabling power factor control through detection of voltage and current, and also improves power quality in distribution boards, switchboards, inverters, motor control panels, solar power connection panels, and ESS. The purpose is to improve power quality and provide a smart heat exhaust system that can detect electrical accidents by expanding the detection area of ultraviolet rays, visible light, and infrared rays emitted from electrical equipment connections and electrical equipment.

In addition, the present invention prevents deterioration of the switchboard or distribution board by discharging internal heat more quickly through the hot air discharge unit, thereby extending the overall lifespan and improving power quality and smart hot air discharge. There is another purpose in providing the system.

In order to achieve the above object, the power quality improvement and smart heat exhaust system according to the present invention includes electrical equipment consisting of a distribution panel, a distribution panel, an inverter, a motor control panel, a solar power connection panel, and an ESS; A power factor adjustment unit installed in the electrical equipment to adjust the power factor by detecting voltage and current, a detection unit with a lens attached to the front to detect smoke along with infrared, ultraviolet, and visible rays generated in a fire, and A main body unit that receives the detected information, calculates an electrical accident risk index, and compares it with a standard threshold to determine whether there is an electrical accident; The detection unit consists of a first detection module with a lens attached to the front to detect infrared, ultraviolet, visible light and gas, and a second detection module configured on one side of the first detection module to receive the detection result of the first detection module. A second detection module is provided with a temperature sensor for detecting the internal temperature to determine an electrical accident and an infrared heat detection unit for detecting infrared heat, and each of the first and second detection modules is configured to form the first and second detection modules. It includes a driving unit that selectively rotates left and right and up and down, and calculates an electrical fire occurrence temperature index by comparing the temperature sensing value detected by the first and second detection modules with a threshold value, and calculates the electrical fire occurrence temperature index according to the electrical fire occurrence temperature index. It is provided with a hot air discharge unit that is selectively driven to discharge heat inside the electrical equipment, and the main body unit includes a main control unit that receives detection results from the first and second detection modules and analyzes parameters, and a result analyzed by the main control unit. It is characterized by comprising a display unit that displays and a communication unit that transmits the analysis results of the main control unit to the outside.

The power quality improvement and smart heat exhaust system according to the embodiment of the present invention has the following effects.

First, the surveillance range can be expanded by using a lens to monitor ultraviolet rays, visible rays, and infrared rays generated in the event of a fire in distribution boards, switchboards, motor control panels, inverters, solar power connection panels, ESS, and electrical equipment connections. .

Second, the angle of the detection module can be adjusted so that the monitoring range of ultraviolet rays, visible rays, and infrared rays generated during a fire can be expanded, thereby reducing the number of sensors.

Third, a detection unit that detects infrared, ultraviolet, and visible light to detect a flame, a gas detection unit, and a power factor adjustment unit are configured in the front, and the infrared heat detection unit is configured as a rotatable detection module in the rear, so that at least one detection unit If a value exceeding the standard value is detected, the infrared heat detection unit rotates to recheck whether a fire has occurred, allowing the user to accurately determine the occurrence of a fire.

Fourth, it is possible to prevent foreign substances from accumulating in the infrared heat detection unit by rotating the detection module when it is not operating so that the infrared heat detection unit is protected by a cover.

Fifth, since one side is located on the inside and the other side is installed on the outside, the manager can easily recognize the dangerous situation from the outside when a dangerous situation occurs while monitoring the inside situation.

Sixth, power quality can be improved by configuring a power factor adjustment unit to enable power factor control for each load through voltage and current.

Seventh, the temperature index for electrical fire occurrence is calculated in the FULL band, and if the temperature index for electrical fire occurrence maintains an upward curve regardless of the discrimination criteria, an alarm can be generated to inform the administrator of the risk of electrical fire, and through administrator option settings. You can prevent the risk of fire by performing controls such as turning off the circuit breaker at your own discretion.

Eighth, by discharging the internal heat more quickly through the hot air discharge part, deterioration of the switchboard or distribution board can be prevented in advance, thereby extending the overall lifespan and improving power quality.

It must be interpreted as meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined clearly. Therefore, the embodiments described in this specification and the configuration shown in the drawings are only one of the most preferred embodiments of the present invention, and do not represent the entire technical idea of the present invention, so at the time of filing the present application, various alternatives may be used to replace them. It should be understood that equivalents and variations may exist.

Figure 1 is a perspective view schematically showing the power quality improvement and smart hot air exhaust system according to the present invention, and Figure 2 is an internal configuration diagram showing the power quality improvement and smart hot air exhaust system of Figure 1 in more detail.

As shown in Figures 1 and 2, the power quality improvement and smart heat exhaust system according to the present invention includes a power factor adjustment and electrical accident detection unit 100 and a main body unit 200.

Here, the power factor adjustment and electrical accident 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. Includes an amplifier 150.

The first detection module 110 has an infrared detection unit 111, an ultraviolet detection unit 112, a visible light detection unit 113, a gas detection unit 114, and a power factor adjustment unit 115 formed at the front in the shape of a cylindrical pillar. ) includes.

In general, light has unique properties such as propagation, dispersion, refraction, scattering, synthesis, interference, diffraction, and polarization. And the speed of light in a material varies depending on the wavelength of the medium, and the refractive index also changes depending on the wavelength. Qualitative dispersion occurs in areas that are far from the intrinsic spectrum line or band of the medium, but anomalous dispersion occurs near the intrinsic spectrum.

This wavelength range of light consists of gamma rays, X-ray rays, ultraviolet rays, infrared rays, and visible rays. Mechanically generated arc flash is composed of the same components as light, and its wavelength band is also composed of the same as light.

Therefore, in order to accurately detect arc flash, various wavelength bands must be detected. Light has the properties of traveling straight and dispersing, and to utilize this effectively, a lens is used in the present invention.

The infrared detection unit 111 measures sensitivity to the infrared wavelength corresponding to 4.3-4.4㎛ of the flame ignited inside electrical equipment such as distribution board, switchboard, inverter, motor control panel, solar power connection panel, and ESS, Preferably, flames in the 4.3㎛ wavelength range are detected.

The infrared detection unit 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 made up of a 4.0-4.8㎛ NBF (Narrow Band Filter) filter chip to detect infrared rays.

Meanwhile, the wavelength generated by the combustion of carbon dioxide generated during combustion exists in the infrared region of approximately 4.3um.

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

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

The ultraviolet detection unit 112 is concentrated in a very short wavelength band among the corona discharge range of 200 to 400 nm, and detects the 380 to 390 nm wavelength band, which has relatively less noise compared to other existing wavelengths.

The visible light detection unit 113 detects sensitivity to visible light wavelengths of 400 nm to 780 nm, more precisely, 430 nm to 470 nm, 530 nm to 570 nm, or 630 nm to 670 nm in one to three locations. Measure visible light by detecting the peak.

The gas detection unit 114 corresponds to a ceramic semiconductor gas sensor that uses the reaction between the surface of a solid and gas, and detects CO through an adsorption reaction according to the operating temperature of the solid surface.

The power factor adjustment unit 115 adjusts the power factor through the voltage and current of electrical equipment corresponding to a distribution panel, switchboard, inverter, motor control panel, solar power connection panel, and ESS.

At this time, the power factor adjustment unit 115 calculates the optimal reactive power by detecting the voltage and current on the load side, learns the capacity of the condenser for the calculated reactive power, and learns the capacity of the condenser for the calculated reactive power. By controlling the power, the power factor can be automatically compensated.

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 condenser when it is greater than a set value.

Additionally, the power factor adjustment unit 115 can perform power factor control for at least one load that requires power factor control for a plurality of loads. Meanwhile, the power factor control determines how much to increase the power factor for the target load and performs power factor control. That is, the power factor is controlled by determining how much the power factor adjustment amount is.

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

Meanwhile, the power factor adjustment unit 115 uses the minimum number of power factor adjustment elements (for example, condensers or reactors) capable of controlling the power factor for each load. At this time, the plurality of power factor adjustment elements may have the same capacity (i.e., the power factor compensation amount is the same), may have different capacities, or may be composed of a mixture of the same capacity and different capacity.

In this environment, the power factor adjustment unit 115 performs power factor adjustment by inputting (connecting) at least one power factor adjustment element corresponding to the power factor adjustment amount among a plurality of power factor adjustment elements to one target load. However, when there are two target loads, the second target load performs power factor adjustment by inputting (connecting) at least one power factor adjustment device corresponding to the power factor adjustment amount among the remaining power factor adjustment devices excluding the power factor adjustment device inputted to the first target load. do. Of course, if there are three or more target loads, the third and fourth load factors are used when adjusting the power factor, excluding the power factor adjustment device input to the previous target load.

For this reason, when the target load is found, the power factor adjustment unit 115 determines which power factor adjustment element to be input to which target load and performs selective control to input the condenser according to the judgment result to the corresponding load. Here, selective control is a control operation that determines which load one power factor adjustment element is connected to (applied to).

Meanwhile, when there are multiple target loads, the power factor adjustment unit 115 randomly determines the priority and performs power factor control, or performs power factor control according to the set priority. Of course, the higher the priority, the faster the power factor control sequence.

The first detection module driving unit 120 includes a first starting point detection unit 121 and a first stepper motor 122, allowing the first detection module 110 to rotate left and right.

Since it is difficult for the first stepper motor 122 to simply calculate the starting point, the first starting point detection unit 121 inserts a circular magnet into a rotating body and places a magnetization sensor capable of recognizing the circular magnet at the starting point to provide accurate By detecting the starting point, the first detection module driver 120 can be rotated to the starting point even after the first stepper motor 122 rotates to return to the original position.

The first stepper motor 122 is connected to the first detection module 110 and rotates the first detection module 110 left and right to attach to the anti-adsorption cover 133, as shown in FIG. 3. The rear second detection module 130, which is protected, is placed forward.

At this time, the infrared detection unit 111, ultraviolet detection unit 112, and visible light detection unit 113, which are located in the front and measure the type and intensity of light, are located behind the anti-absorption cover 133 to create a dark room. Correction or failure determination can be made, and if a failure occurs, the fact of the failure is transmitted so that the worker or manager can check it through the alarm unit 208 or the display unit 209.

Meanwhile, the second detection module 130 is formed integrally with the first detection module 110 and behind the first detection module 110.

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

The second non-contact temperature sensor 131 detects temperature changes using a negative temperature coefficient (NTC), which has the characteristics of a negative resistance temperature coefficient and a property in which the resistance value decreases as the temperature rises.

Meanwhile, the outside of the negative temperature coefficient is insulated with epoxy to prevent component damage due to electrostatic discharge (ESD).

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

At this time, the temperature value measured by the second non-contact temperature sensor 131 is compared with the temperature value measured by the infrared heat detection unit 132 protected by the adsorption prevention cover 133, It is desirable that it can be used as a reference value to determine whether there is a failure of (132).

Also, at this time, if a failure occurs in the infrared heat detection unit 132, the fact that the sensor has failed is transmitted so that the worker or manager can check it through the alarm unit 208 or the display unit 209.

The infrared heat detection unit 132 measures the surface temperature by measuring the amount of infrared rays emitted (radiated) from the object.

That is, the infrared heat detection unit 132 measures infrared radiant heat emitted from an object and calculates the temperature based on the measured infrared radiant heat value.

Meanwhile, when an electrical fire occurs, an infrared detection unit 111, an ultraviolet detection unit 112, a visible light detection unit 113 formed in front of the first detection module 200 by the exhaust (smoke) generated simultaneously, and The accuracy of the measured value of the gas detection unit 114 decreases.

At this time, the second non-contact temperature sensor 131 and the infrared heat detection unit 132 of the second detection module 130 formed behind the first detection module 110 are located forward and detect heat with infrared rays to detect high temperature. By detecting, it reliably determines the occurrence of a fire.

The infrared heat detection unit 132 as described above is capable of non-contact measurement, can quickly and accurately check the surface temperature to diagnose deterioration, and can ensure the safety of workers because measurement is possible without direct contact with the measurement object. In addition, damage to the device itself can be minimized.

In particular, the infrared heat detection unit 132 can safely measure a high temperature measurement object, perform measurement without damaging or destroying the measurement object, and perform measurement without interfering with the process, and can be used at industrial sites. Since measurements can be performed without stopping the equipment, unnecessary costs due to facility downtime can be prevented.

However, the infrared heat detection unit 132 cannot penetrate transparent glass and acrylic, so a lens such as transparent glass or acrylic cannot be formed on the front, so the probability of foreign substances penetrating is high, so it is necessary to minimize the penetration of foreign substances. 1 It is located at the rear due to the rotation of the detection module 110 and is protected by the dust absorption prevention cover 133.

The second detection module driving unit 140 includes a second starting point detection unit 141 and a second stepper motor 142 and drives the second detection module 130 to rotate up and down.

Since it is difficult for the second stepper motor 142 to simply calculate the starting point, the second starting point detection unit 141 inserts a circular magnet into a rotating body and places a magnetization sensor capable of recognizing the circular magnet at the starting point to provide accurate In order to detect the starting point, the second detection module driver 140 is rotated to the starting point even after the second stepper motor 142 rotates to return to the original position.

The second stepper motor 142 is connected to the second detection module 130 and rotates the second detection module 130 to move it up and down.

The signal amplifier 150 is equipped with an amplifier circuit to receive the signal detected by the sensors of the first detection module 110 so that it can be easily analyzed by the main control unit 201 of the main body 200 when necessary. By amplifying, the detection ability is improved by generating an ideal value without abnormal oscillations or ripples induced by external frequencies.

The main body unit 200, which receives the signal detected by the power factor correction and electrical accident detection unit 100 and ultimately determines whether or not there is an electric fire, includes a main control unit 201 and an indicator light 202, as shown in FIG. 2. , aerosol driving unit 203, first contact 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 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 an electrical fire risk index (EFRI). :Electric Fire Risk Index) is calculated and the size is compared with the standard threshold to control the first detection module 110 and the second detection module 130 to determine the occurrence of a fire with different reference thresholds depending on the temperature value, You can check the internal situation through messages, voices, and lights.

The main control unit 201 analyzes the analog signals detected by the sensors of the first detection module 110 and converts them into digital signals, that is, digital signal processing.

The indicator light 202 receives and analyzes the value detected by the detection units of the first detection module 110, and if the main control unit 201 determines that the value is an absurd value, a malfunction or inspection, it displays a color, or Inspection requests are displayed in a blinking pattern so that workers or managers can check them from outside.

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

The first contact temperature sensor 204 measures the temperature of one or more busbars in the electrical equipment by contact, and when a temperature exceeding a threshold is measured, the alarm unit 208 or the display unit 209 indicates deterioration of the corresponding busbar. ) to prevent deterioration by generating early notification.

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

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

That is, the first contact temperature sensor 204 compares the temperature (bus duct temperature - ambient temperature) and calculates 5 degrees higher than the ideal temperature standard of 65 degrees through the calculation formula By keeping the temperature low, the risk of bus duct deterioration is detected early.

The communication unit 205 is equipped with one or more communication modules among IC2C, RS485, MOD-BUS, Wife, Can, and Bluetooth, and communicates with an external server or a smart terminal of the manager who manages the electrical equipment, while detecting the first The detection information detected by the module 110 or the second detection module 130 is transmitted to the relevant external server so that the internal situation of the electrical equipment can be checked.

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 detects and displays less than 10V as normal, 10V to less than 20V as caution, 20V to less than 30V as inspection, and 30V or more as emergency, or may notify the user through the communication unit 205. .

The limits of the human body's reaction and death due to electric shock are difficult to determine uniformly due to the fact that human experiments are difficult due to their nature, and no matter what experiment results are obtained, they are difficult to verify, human diversity, and situational variables at the time of the disaster. The degree of risk in the event of electric shock is largely determined by the size of the energized current, energized time, energized path, and type of power source.

The effects of electric shock on the human body can be broadly divided into two types. First, the electrical signal stimulates nerves and muscles, impeding normal function and causing respiratory arrest or ventricular fibrillation. Second, the electrical energy is a phenomenon in which biological tissue is damaged. It causes structural damage such as destruction or damage.

The emergency power unit 207 is a lithium polymer battery that is normally charged and can be used by supplying power on its own when the power is cut off in the event of an electric fire.

The alarm unit 208 outputs the values detected by the detection units included in the first detection module 110 or the second detection module 130 as sound, or outputs a warning message or warning sound in case of a dangerous situation.

The display unit 209 may display values detected by the infrared detection unit 111, ultraviolet detection unit 112, visible light detection unit 113, gas detection unit 114, and infrared heat detection unit 132. And, if a risk of fire is expected based on the detected value, this can be displayed.

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

The manipulation unit 211 is formed on the surface of the main body 200 and is provided with an up key, a down key, a menu key, an enter key, etc., to operate the first detection module 110 or the second detection module 130. can be set by the user.

For example, the user operates the operation unit 211 to detect the infrared detection unit 111, the ultraviolet detection unit 112, the visible light detection unit 113, And only one of the gas detection unit 114, the second non-contact temperature sensor 131 formed in the second detection module 130, or the infrared heat detection unit 132 is operated, or more than one detection unit is operated. The second detection module 130 can be operated according to the operation of the infrared detection unit 111, ultraviolet detection unit 112, visible light detection unit 113, and gas detection unit 114. You can also do it.

The program writing terminal 212 is connected to a PC, laptop, or smart device to remove, add, or update programs necessary for the operation of an electric fire detection system using an optical sensor and a gas sensor using multiple radar light-receiving lenses. It is configured to do so.

The laser irradiation unit 213 is formed on the outside of the electrical equipment 2, as shown in FIG. 4, and emits high-brightness laser light to the ground or wall, etc. to easily inform the manager of the internal situation of the electrical equipment 2. Investigate.

That is, the laser irradiation unit 213 clearly displays a danger mark on the floor when a danger occurs, that is, displays it in red to inform managers and users of the danger and facilitate quick escape from danger or repair.

In addition, the laser irradiation unit 213 can illuminate a danger sign toward the floor with a strong laser. For example, it can be mounted in a selection of green, blue, and red depending on the location of use, or green, blue, and red can be integrated into one. It is equipped with a laser that can emit different lights depending on the situation.

Additionally, the laser irradiation unit 213 can display various warning signs such as no access, electrical hazard, or fire hazard.

That is, the first detection module 110 has an infrared detection unit 111, an ultraviolet detection unit 112, a visible light detection unit 113, a gas detection unit 114, and a power factor adjustment unit 115 formed at the front. , A second detection module 130 is formed at the rear, consisting of a second non-contact temperature sensor 131 and an infrared heat detection unit 132. In normal times, an infrared detection unit 111, an ultraviolet ray detection unit 112, and a visible light sensor are used. The detection unit 113 and the gas detection unit 114 are located at the front, and as shown in FIG. 6, they rotate only when necessary, and the second non-contact temperature sensor 131 and the infrared heat detection unit 132 at the rear are located. 2 The detection module 130 is positioned forward and driven.

The electric fire detection method using the power quality improvement and smart hot air discharge system according to the present invention having the above-described configuration will be described in more detail with reference to FIG. 9.

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

That is, the main body unit 200 measures the infrared detection unit 111, the ultraviolet detection unit 112, the visible light detection unit 113, and the gas detection unit 114 of the first detection module 110. Receives infrared, ultraviolet, visible, 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 performs a step of comparing the ultraviolet rays sensed by the ultraviolet ray detection unit 112 with a threshold value (S210).

Additionally, the main control unit 201 uses the infrared wavelength sensed by the infrared detection unit 111 as the flame value to compare the flame value and the threshold value (S220).

Additionally, the main control unit 201 performs a step of comparing whether the visible light value detected by the visible light detection unit 113 is greater than a threshold (S230).

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

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

If the CO value in step S300 is not greater than the threshold, step S100 is repeated, and if the CO value is greater than the threshold, the main control unit 201 determines the Electric Fire Risk Index (EFRI). The step of calculating is performed (S400).

The main control unit 201 compares the electrical fire risk index (EFRI) calculated in step S400 with a reference threshold 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, warning light, and warning sound in different forms through the inspection request indicator light 202, the display unit 209, or the alarm 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 greater than or equal to the standard threshold value of 70 (S511).

In step S511, if the electrical fire risk index exceeds the standard threshold value of 70, the main control unit 201 rotates the first detection module 110 so that the rear infrared heat detection unit 132 can be placed forward. A step of controlling the first detection module driver 120 is performed (S512).

The first detection module 110 rotates and the infrared heat detection unit 132 disposed forward has a resistance value that decreases as the temperature increases. When the infrared temperature value is measured, the main control unit 201 detects the infrared temperature. The step of receiving the value is performed (S513).

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

If the infrared temperature value is greater than the temperature value threshold in step S514, the main control unit 201 determines that a fire has occurred in electrical equipment such as a distribution board, distribution board, etc., and the power supply of the power cable connected to the electrical equipment may be tripped. Steps are taken to display a fire message and a red light along with a trip signal (S515).

On the other hand, the main control unit 201 repeats step S100 if the infrared temperature value is not greater than the temperature value threshold in step S514.

In step S511, if the electrical fire risk index does not exceed the reference threshold of 70, the main controller 201 sets the electrical fire risk index (EFRI) to another reference threshold, that is, the reference threshold of 35. A step is performed to determine whether it is greater than 70 or less than 70 (S521).

In step S521, if the electrical fire risk index exceeds the standard threshold of 35 and is less than 70, a fire warning message is output and a yellow light is displayed as a warning light (S522).

In step S521, if the electrical fire risk index is greater than 35 and is not included in the range of less than 70, a step is performed to determine whether it is another standard threshold, that is, less than 35 (S531).

If the electrical fire risk index is less than the standard threshold value of 35 in step S531, the main control unit 201 performs a step of displaying a fire safety message on the display unit 209 (S532).

If the electrical fire occurrence risk index in step S531 is less than the standard threshold value of 35, step S100 is repeated.

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

The second contact temperature sensor 215 measures one or more temperatures in the electrical equipment, and when a temperature above a threshold is measured, it notifies the system of deterioration in advance through the alarm unit 208 or the display unit 209. This causes deterioration to be prevented.

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

As shown in FIGS. 11 and 12, the hot air discharge unit 214 is coupled to a driving fan 214a with a plurality of rotary blades attached diagonally to the central axis and the central axis of the driving fan 214a. A vortex fan (214c) is connected and consists of an annular disk and a plurality of vortex blades arranged and fixed in the radial direction along the edge of the annular disk, and on a connecting shaft between the driving fan (214a) and the vortex fan (214c) It is connected by means of a bearing, supports the connecting shaft while forming an intake port of a certain size, and is provided with a bracket 214b attached to the end of the intake port of the exhaust pipe (not shown).

Here, the bracket 214b is connected to the connecting shaft between the driving 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 driving fan 214a, and the end It supports the connecting shaft while forming an intake port of a certain size, and is fixed to the end of the intake port of the exhaust pipe by fitting or bolting.

The vortex fan (214c) is arranged to surround the center (A) coupled to the motor shaft of the motor, the rotating plate (B) coupled to the center (A), and the outside of the rotating plate (B) and along the outer peripheral surface. A circular band member (C) in which a plurality of pins protrude radially outward, and a plurality of connecting rods (D) for vortex generation that extend radially from the outer peripheral surface of the rotating plate (B) to the inner peripheral surface of the circular band member (C). ), including.

The hot air discharge unit 214 configured as described above is configured to rotate the vortex fan 214c by the rotational force of the driving fan 214a, and discharges contaminants with a greater specific gravity than air, including hot air.

Since the hot air discharge unit 214 has a collection capacity 3 to 6 times that of a general exhaust fan, when installed in a distribution board including a distribution panel, it can not only collect internal pollutants and discharge them more quickly, but also can be used in a general exhaust fan. Compared to , electricity consumption can be reduced.

Meanwhile, the hot air discharge unit 214 needs to be controlled because there is a high risk of the fire expanding when it is operated when a fire occurs.

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

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

At this time, the comparison of the temperature sensing value and the threshold value is performed by repeatedly receiving the temperature sensing value of step S100, which is in sleep mode, and waking up to calculate the temperature index for occurrence of an electrical fire when determining an abnormal state.

That is, if the temperature sensing value is higher than the threshold value, the temperature sensing value is received again and steps S210, S220, and S230 are repeatedly performed, and if the temperature sensing value is lower than the threshold value, the temperature sensing value is fed back to step S100. It receives the sensing value and performs the threshold value and steps S210, S220, and S230 repeatedly.

Next, the temperature sensing value and the threshold value are compared to calculate the temperature index for occurrence of an electrical fire (S300).

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

Meanwhile, the calculation of the electric fire occurrence temperature index continues, and even when hot air discharge is in progress, the electric fire occurrence temperature index is calculated. If the electric fire occurrence temperature index does not decrease, the operation of the hot air discharge unit 214 is stopped.

In addition, if the electrical fire occurrence temperature index is calculated in the FULL band and the electrical fire occurrence temperature index maintains an upward curve regardless of the determination standard, 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 fire hazards by performing controls such as turning off circuit breakers through self-judgment through administrator option settings.

Therefore, by discharging the internal heat more quickly through the hot air discharge unit 214, deterioration of the switchboard or distribution board can be prevented in advance, thereby extending the overall lifespan and improving power quality.
