The device has the advantages of simple structure, accurate position judgment and reliable insulation, and doesnot affect the normal running state of a line.

Description

technical field [0001] The invention relates to the field of power supply equipment, in particular to an intelligent monitoring device for the position of an isolating switch of an overhead power distribution line. Background technique [0002] At present, the isolating switch (knife switch) of 10kV distribution line is widely used. The "four strict precautions" of distribution network automation require the side of the 10kV line contact switch and the load side of the first segment of the main line to be equipped with an isolating switch to ensure power failure. There should be obvious disconnection points at each end of the line or equipment, and the location of the isolation switch becomes particularly important. When the line is powered, it is necessary to ensure that the knife switch is in the closed position before informing the dispatcher to apply for remote operation of the switch. The dispatcher cannot know the position of the knife switch through the system or the ...

Problems solved by technology

When the line is powered, it is necessary to ensure that the knife switch is in the closed position before notifying the dispatcher to apply for remote operation of the switch. The dispatcher cannot know the position of the knife switch through the system or the monitoring screen.

In actual work, the switch can only be manually operated by on-site personnel, and the dispatcher cannot monitor the working status of the switch in real time, resulting in low work efficiency. Therefore, real-time monitoring of the position of the switch is very important to ensure that the power supply is stopped
