Description
The present invention relates to a device for checking the insulation gas of the ground switch, and more particularly, the state of the insulating gas filled in the ground switch is to be automatically checked in real time, when the abnormal phenomenon is measured while telling the contents of the abnormal phenomenon The present invention relates to an insulation gas check device for a ground switch, wherein the ground switch can be safely and conveniently managed by remote control.
In general, the power supplied to the consumer side in the substation is usually boosted to about 22,000 ~ 26,000V, and in large cities, power cables are buried underground in consideration of the beauty of the city.
In this case, in order to protect the power system, the electric power company installs and uses a ground switch that can control the power supply to the ground or the outside of the sidewalk.Insulation gas is accumulated inside the ground switch. Also known as sulfur fluoride (SF6) gas (hereinafter referred to as "insulation gas"), it has excellent physical, chemical, and electrical properties, excellent insulation strength (about 3QQ / 1 atm of air), and excellent arc extinguishing capacity. Suitable.
When the gas is poor in gastightness, the gas is corrosive, or when moisture is contained in the gas, which in turn corrodes the insulation or metal, it insulates insulation and degrades the performance of the insulation. You can't block.
Therefore, the maximum pressure, moisture content, refrigerant temperature, and sulfurous acid gas content of the insulating gas should be periodically checked. For this purpose, the internal pressure measurement of the switch, the moisture content, the refrigerant temperature, and the sulfurous acid gas content are determined through the respective mechanisms. Not only does it take a lot of time and manpower because of the measurement check, but it also causes various problems in that the insulation gas cannot be measured and checked effectively.
In order to solve the above problems of the ground switch, Korean Unexamined Patent Publication No. 1999-64380 (hereinafter referred to as Prior Art 1) and Japanese Laid-Open Patent Publication No. 14-027623 (hereinafter referred to as Prior Art 2) are devised. It has been.
However, prior art as described above, means for measuring the above items related to the measurement of the insulating gas (the measuring means is represented in the prior material 1, but for the present invention gas pressure detector, decomposition gas detector, temperature detector of the prior material 2 The measured data are stored in the data storing means, and the processing unit continuously reads and processes the accumulated data, and then accumulates the processing result processed by the processing unit. It is only characterized by issuing an alarm through the alarm means when it is stored in the means, displayed on the display means, and when it is determined that an abnormal value higher than the reference value stored in the processing portion is detected.
Accordingly, when an outlier is measured in any one of the above items, and an alarm is triggered, the technician goes directly to the ground switchgear, investigates the cause of the occurrence of the abnormality, and repairs the cause of the occurrence of the abnormality. The same system has a problem that it is difficult to immediately respond when the alarm means is issued at night, as well as the immediate response is difficult when the corresponding ground switch is far from the alarm means.
In addition, when the ground gas switch is filled with insulation gas as described above, if a problem occurs in the insulation gas, the countermeasures against the conventional problems are more urgent in view of the fact that the damage is very large unless immediate and appropriate measures are taken. You can do it.
The present invention has been made to solve the above problems,
Insulation gas of the ground switch comprising a measuring means for measuring the state of the insulating gas, an abnormality determining unit for determining whether the measured value measured by the measuring means is abnormal, and a display unit for displaying the contents when the abnormality occurs. A wireless communication unit for remotely transmitting the contents of the abnormal phenomenon expressed through the display unit and receiving a control command for the contents, a control unit connected to the wireless communication unit and controlled according to the control command; Forming an insulation gas tank connected to the control unit, by controlling the action on the insulation gas abnormality inside the ground switch remotely, so that the ground switch can be safely and conveniently managed, the insulation gas check device of the ground switch An object of the present invention to provide a.
Hereinafter, to solve the present invention to achieve the above object.
The present invention is formed on one side of the ground switch, measuring means for measuring the state of the insulating gas; An abnormality determining unit connected to the measuring unit to determine whether the measured value is abnormal; In the insulation gas check device of the ground switch comprising a display unit to display the contents when the abnormal phenomenon is measured in connection with the abnormality determination unit, a transmitter for remotely transmitting the insulation gas state measurement information expressed through the display unit; A wireless communication unit including a receiving unit for receiving a control command for the transmitted insulation gas state measurement information; A control unit connected to the wireless communication unit to process the received control command; An insulated gas tank connected to the control unit to control the insulated gas supply by the control unit; Characterized in that the insulating gas check device of the ground switch comprising a.
In addition, the control unit of the present invention, the central operation processing unit input the insulation gas reference value information according to the insulation gas state measurement information, the feedback circuit for controlling the insulation gas tank so that the measured insulation gas state measurement information meets the insulation gas reference value Characterized in that the insulating gas check device of the ground switch comprising a.
In addition, the ground switch of the present invention, one side end of the tube tube is fastened by using a connection port on one side thereof, the measuring means is connected to the side of the tube tube, the other end of the tube tube is formed with a flow regulator It is characterized by the insulation gas check device of the ground switch.
In addition, one side of the tube tube of the present invention is characterized in that the insulating gas check device of the ground switch is connected to the collecting pipe valve collecting pipe for collecting the insulating gas extracted from the ground switch separately.
The present invention configured as described above can be expected the following effects.
First, in the ground switch that maintains the flow of electricity safely through the insulating gas, the state of the insulating gas and its internal state to be measured in real time, if the abnormality occurs by the measuring means to display the contents through the display unit However, by enabling the immediate action according to the displayed content through the remote control, there is an effect that can effectively maintain and manage the ground switch.
In particular, in the case of a ground switch using an insulating gas that has a high possibility of a large accident when the response to the accident is inadequate or delayed compared to other insulated ground switches, a conventional technology that displays only when an abnormal phenomenon occurs inside. Compared to the conventional method, it is possible to immediately measure the abnormality of the insulating gas through remote control, and if the technician is difficult or delayed, the degree of damage can be significantly reduced as compared to the conventional method. Considering the high reconstruction cost of the ground switch using the above, the economic effect of the insulated gas tank set as the corresponding device will be further increased.
Second, by real-time measurement of the internal abnormality and its contents can be transmitted remotely and the control command can be remotely controlled according to the ground switch itself, to check and repair the ground switch as compared to the conventional configuration. There is an effect that can significantly reduce the cost spent on.
