Description

[0001] The present invention relates to a self-diagnostic system of switchboard capable of central control monitoring,
BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a power management self-
The present invention can be applied to a field in which a temperature sensing unit senses a temperature of a predetermined space and a determination is made as to whether a predetermined space is normal or abnormal based on the sensed temperature processing result, and in a field requiring heat dissipation.
The present invention is also applicable to a case in which a function necessary for a product is directly operated by a control device configured in a product by applying a thing Internet technology or a remote control is performed by a control device (for example, a remote server, It is applicable to the field where it is possible.
Collective power consumers such as schools, buildings, apartment complexes, and factories require switchboards to receive the extra high voltage supplied from the substation and convert it to a commercial voltage with an appropriate low voltage, in order to obtain the required power.
Such a switchboard includes a high-voltage transformer that converts a special high voltage to a low voltage in a closed enclosure, a fault switch automatic switch that switches a high voltage input line to a meter transformer, and a high voltage fuse of a current type. Accordingly, heat is generated in a high-voltage transformer or the like, and the temperature inside the enclosure rises.
Excessive rise of the internal temperature of the enclosure in the switchboard may degrade the operation efficiency and accuracy of various parts and devices, and may cause fire. Therefore, most of the internal temperature monitoring circuit is installed, When it is detected that the temperature has been reached, the cooling fan is started immediately to forcefully drop the internal temperature of the enclosure.
The temperature cooling operation inside the cabinet of the switchboard through the forced ventilation can solve the problem that the heat radiation efficiency is high and the resistance thermometers of the connection terminals and the bus bars of various devices and equipments in the apparatus are increased and power loss is caused.
However, since the heat dissipation operation of the switchboard through the forced ventilation causes inflow of fine dust from the outside, and also the inside fine dust is dispersed and relocated and fixed, the resistance temperature coefficient of the terminal or bus bar of various equipments, .
In addition, the driving of the heat-dissipating fan, that is, the cooling fan, for controlling the temperature inside the switchboard also increases the cost due to power consumption.
A specific prior art is Korean Patent Registration No. 10-09037780.
This registration technology has a structure for discharging the heat inside the cabinet by forced air blowing using two fans, in which a ventilation plate for convection of air is mounted between the cabinet of the cabinet and the outside air, And at the same time, it conveys the inside of the switchboard, thereby discharging the heat to the outside and ventilation, thereby preventing the condensation phenomenon. However, it was difficult to completely solve the above-mentioned problem.
Another prior art is Korean Patent Registration No. 10-1197428.
This registration technology maximizes the heat dissipation effect by structurally designing the heat dissipation structure as the upper part and the lower part so that the internal heat is discharged to the outside by operation of the fan and operation of the opening and closing plate when the temperature inside the hybrid- And the operation of the opening and closing plate and the fan are automatically performed according to the setting temperature and the effect of the setting temperature. The entire surface of the variable portion is made of reinforced plastic or tempered glass, So that the administrator can easily check the internal state.
However, this registration technique was also difficult to completely solve the above-mentioned problem.
The above-mentioned conventional techniques are common in that they are technologies using fans which are forced ventilation devices.
In contrast, some techniques for keeping air temperature inside the switchboard below a certain temperature using a louver are also known.
When the louver is installed at the upper part, there is no countermeasure against condensation, and the louver structure is formed on the side surface only when the temperature rise exceeds the reference temperature due to the settling of contaminants such as dust.
However, in this method, the difference in height between the inlet of the HC and the EXHUAST louver, that is, 2.3 m in the upper installation and 1.5 ~ 1.8 m in the rear installation, There is a problem that the effect of releasing the cursor heat is not large.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiments of the present invention are described in order to more fully explain the present invention to those skilled in the art, and the following embodiments may be modified in various other forms, The present invention is not limited to the embodiment. These embodiments are provided so that this disclosure will be more faithful and complete, and will fully convey the scope of the invention to those skilled in the art.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a," "an," and "the" include singular forms unless the context clearly dictates otherwise. Also, the term "comprising" when used in this specification is taken to specify the presence of stated features, integers, steps, operations, elements, elements and / Elements, and / or groups.
Most of the switchboards under 22.9kV manufactured and installed in Korea use vacuum breakers as breakers and they are operated by connecting them with bus bars made of copper.
Vacuum circuit breaker is an assembly made up of mechanical mechanism, and it will be continuously aged after installation. When the spring is worn out and the mechanism wears down, the pressing force of VI (VACCUM INTERRUPTER) is weakened, ARC energized state may occur.
The vacuum circuit breaker in the switchgear and copper buses are in contact with each other with fastening bolts and clips. When the vacuum circuit breaker is operated, an impact of about 450kgf X 3 (phase) occurs. A problem arises.
 In addition, a large number of failures due to heat generation and malfunction due to fastening and loosening of the connecting portions and poor contact between the contact portions are generated.
Inside the Switchgear (MCSG), the temperature measurement is structurally inevitable, and it is practically difficult to monitor the temperature of the circuit breakers on a daily basis.
In order to detect the risk of an accident early and to maximize the efficiency of safe operation management, it is desirable to construct a constant temperature monitoring system in the switchboard and connect it to a centralized device (DB SEVER) so that it can be monitored in the field and control room.
In other words, as an insulation and partial discharge monitoring system in a switchgear, a vacuum circuit breaker is a device that cuts off a normal current and a fault current flowing in the system by using a mechanical mechanism, and is equipped with a mechanism and insulates the main circuit portion and the mechanism portion In order to ensure the insulation between the panel enclosure and the internal diaphragm, the busbars and the energized parts of the switchgear are fixed using various insulating materials, and they are deteriorated due to deterioration, corrosion, Many ground and short-circuit faults have occurred due to insulation breakdown due to insulation deterioration caused by insulation.
However, the breaker and insulation installed in the switchgear can not check the progress of the insulation breakdown during operation. It is impossible to measure the insulation by measuring the insulation by pulling out the device every day for a large number of switchgears.
Therefore, it would be highly desirable to construct a system that inspects the insulation state at all times in order to prevent ground fault and short circuit caused by insulation breakdown, and connect the system to a centralized device so that it can be monitored in the field, control room and office .
In order to satisfy these requirements, the present invention divides the inside of the switchboard into a plurality of temperature zones according to the state in which the respective components are disposed, and determines whether the components are normal or abnormal based on the sensed temperatures . The present invention also incorporates a technique for releasing the interior heat of a control cabinet to the outside, with or without associated with internal components of the cabinet.
As shown in FIG. 1, when the thermal image sensor 2 detects the internal temperature of the switchboard 1 and the detected temperature is processed in the control device, An operation of determining whether the operation is normal or abnormal according to the processed result, and an operation of releasing the internal heat of the switchgear are simultaneously or selectively performed. The sensed data of internal temperature of the switchboard is shared by a controller configured at a switchboard and a controller configured at a remote location.
At this time, the internal temperature of the switchboard is determined as a whole for the heat dissipation, and it is judged for each of the plurality of divided temperature zones in order to judge whether the devices or the electrical connecting parts constituted inside the switchboard are normal or abnormal.
Here, each of the divided zones may be exemplified by dividing the interior of the switchgear into five temperature zones as shown in FIG. 2, and judges whether or not the temperature of each of the divided zones exceeds the reference (normal) temperature. Here, the sensing temperature refers to the temperature sensed in each zone, and the sensing determination temperature means the temperature of each zone, more precisely, the temperature judged to be the final temperature of the zone . The concept of determining the final temperature on the basis of the degree of influence of each zone on the other zones is shown in FIG.
For example, since the inside of the switchgear is constituted by various devices, wiring, and electrical coupling parts, the position where the devices are arranged is divided by various various methods such as up and down or left and right, and the temperature generated in each of the divided areas is detected will be. The temperature sensing is enabled by the thermal image sensor as described above, and the sensed image is processed in the controller to determine the temperature for each zone.
3, considering that the heat generated inside the switchgear is normally directed upward, for example, when the temperature sensed in a predetermined area due to the heat moving upward is detected to be higher than the reference temperature The temperature of each zone is finally judged in consideration of this point.
Since the heat is typically moved upward, for example, as shown in FIG. 2, the uppermost portion of the interior of the switchgear is set to the first temperature zone, and the second, third, fourth, and fifth temperature zones It can be inferred that the heat generated in the third, fourth, and fifth temperature zones particularly affects the first and second temperature zones. Therefore, for example, even if the temperature sensed in the first and second temperature zones is higher than the reference temperature, a certain allowable value is set in advance and it is judged that the temperature of the zone is normal unless it exceeds the allowable value can do.
The solenoid of the present invention can be controlled by a control device configured in a switchboard or by a remote control at a remote place and the solenoid can be controlled by a control device .
On the other hand, if any one of the divided temperature zones deviates from the reference temperature range, it may be controlled to perform heat dissipation.
As shown in FIG. 1, the server and the server 200 are networked through the Internet network N, in which the central control and monitoring of the present invention is possible. The switchboard 1 constitutes a control device as will be described later.
In FIG. 1, the server 200 may be, for example, a smart phone and other devices capable of wired and wireless Internet. The Internet network N is a wired / wireless communication network.
5, the control apparatus constructed in the switchboard of the present invention includes a control unit 110, a receiving unit 120, a transmitting unit 130, a temperature sensor 140, a memory 150, a display unit 160, (170).
The control unit 110 determines and displays the internal temperature of the switchboard for the purpose of the present invention and controls the object-based Internet to perform the heat dissipation based on the detected internal temperature of the switchboard, So as to control the overall flow of returning the internal temperature of the switchboard to the normal temperature.
The internal temperature reference value is stored and managed in the memory 150 in the above-
The receiving unit 120 receives a remote control signal for internally radiating heat from the server 200, which is transmitted from the server 200.
The transmitting unit 130 transmits a processing signal of the switching room internal temperature sensing signal to the server 200.
The temperature sensor 140 senses the interior temperature of the switchgear. The temperature sensor 140 may be the above-described thermal image sensor, or may be a sensor installed at a predetermined position in the switchboard. If the thermal image sensor is used, for example, the temperature at which the internal temperature of the switchboard is highest may be compared with the reference temperature, and the internal temperature may be higher than the reference temperature. When the temperature sensor 140 is used, the temperature to be maintained in the interior of the switchgear is typically set as a reference temperature, and when the temperature detected by the temperature sensor is higher than the reference temperature, heat can be dissipated.
The memory 150 stores the internal temperature of the switchboard detected by the temperature sensor 140 when the control unit 110 processes the internal temperature.
The display unit 160 externally displays the internal temperature value processed by the controller 110 and stored in the memory 150 so that the user can confirm the internal temperature value.
The heat dissipating unit 170 opens and closes the upper cover of the power transmission / reception unit when the internal temperature of the power transmission / reception unit exceeds the reference temperature.
The heat dissipation unit 170 may include a solenoid 176 driven by a solenoid driver 175. The heat dissipation can be made possible by opening the upper portion of the power and control panel as the power and control panel upper cover 11 is pushed up when the solenoid 176 is driven. When the heat radiation is completed, the driving of the solenoid 176 is also completed, so that the upper cover 11 of the power /
A hinge may be formed on one side of the upper cover 11 and an opening range may be defined on the other side for opening or closing the upper cover of the power distribution panel by the solenoid 176. [ The open range defining structure may be connected between a predetermined point of the upper cover 11 and the side panel of the switchgear. That is, when the solenoid 176 is driven, the hinge acts as a rotation center axis of the upper cover 11, and the upper cover 11 is opened, and the heat is transmitted to the outside.
When the internal temperature of the switchboard 1 configured as described above is determined to be outside the reference value, the heat radiation is automatically performed.
6, the server 200 of the present invention includes a control unit 210, a receiving unit 220, a transmitting unit 230, an operating unit 240, a memory 250, and a display unit 260.
The control unit 210 processes the internal temperature sensed by the transmission and reception unit 130 transmitted from the transmission unit 130 of the switchboard 100 and remotely controls the opening of the switchgear upper cover 11 based thereon. The control unit 210 substantially performs the same operation as the control unit 110 of FIG.
The receiving unit 220 receives the temperature detection value of the interior of the switching room, which is transmitted from the switchboard 1.
The transmitting unit 230 transmits a remote control signal for opening the switchgear upper cover 11 to the switchboard 1 side based on the result received by the receiving unit 220 and processed by the control unit 210.
The result processed by the controller 210 is a result of determining whether the sensed temperature value is within a range required for heat dissipation. To this end, the server 200 stores and manages a reference value for heat dissipation in the memory 250.
The operation unit 240 is configured to be operated to remotely control the switchboard 1 when it is determined that the sensed temperature value deviates from a reference value and heat radiation is required. An operation signal by the operation unit 240 is processed by the control unit 210 and the control unit 210 remotely controls the switchboard 1 to perform an operation in accordance with an operation signal by the operation unit 240. [
The memory 250 stores the sensed temperature value processed by the controller 210.
The display unit 260 displays the sensed temperature value processed by the controller 210 to the outside so that the remote controller can recognize the sensed temperature value.
The server 200 configured as described above inputs a remote control signal so that heat is radiated through the operation unit 240 when it is determined that the sensed temperature value transmitted from the switchboard 1 is a value requiring heat dissipation.
That is, the control block of the server 200 is a remote control for radiating heat at the judgment of the user, and the control block of the server 1 is a control for radiating heat by automatic judgment.
However, the present invention is not limited to this, and the server 200 may be configured to be capable of automatic heat radiation control.
The operation flow of the object-based Internet < RTI ID = 0.0 > switchboard control system < / RTI >
First, the interior temperature of the switchgear sensed by the temperature sensor 140 in real time is input to the controller 110.
The sensing signal is processed in the controller 110 and then stored in the memory 150. [
The sensed temperature value processed by the controller 110 is compared with a reference temperature value managed in advance.
If the detected temperature value is higher than the reference temperature value in step S40, the controller 110 transmits a control signal to the solenoid driver 175 so that the solenoid 176 is driven.
As the solenoid 176 is driven, the upper cover 11 of the switchgear is pushed up and the upper portion of the switchgear is opened (S70), and the internal heat of the switchgear is released to the outside.
The temperature sensor 140 senses the internal temperature of the switchgear and inputs the detected temperature to the controller 110 during the heat release.
Accordingly, the control unit 110 compares the sensed temperature value with the reference temperature value, and maintains the solenoid 176 driven according to the comparison result to continue the heat emission or to stop the driving to stop the driving of the solenoid 176, To be closed.
Meanwhile, the sensed temperature value, which is processed by the controller 110 and stored in the memory 150, is transmitted to the server 200 located at a remote location through the transmitter 130.
Therefore, the receiving unit 220 of the server 200 receives the information and inputs the information to the control unit 210. The control unit 210 processes the information and stores the processed information in the memory 250, displays the information through the display unit 260, Let the user know.
Accordingly, when a user located at a remote location determines that heat needs to be radiated, a heat radiation control signal is input by the operation unit 240, and the control unit 210 controls the transmission unit 230 to transmit a remote control signal to the control unit The control unit 100 of the switchboard 100 receives the control signal from the receiving unit 120 and processes it in the control unit 110 and controls the upper cover 11 of the switchboard 1 to perform heat radiation in the field .
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Lt; / RTI >
