Description

technical field

[0001] The invention relates to a power supply line detection system, and more specifically relates to an ultra-high voltage line monitoring system for solar power generation. Background technique

[0002] Power lines often have short circuits, ground faults, and stolen wires. Severe weather such as strong winds, rain, snow, and freezing will also cause line faults. It is very difficult to find and locate faults. In order to improve the power supply reliability of the power grid, at present, key points such as power plants, substations and branch points in the power grid, as well as special transformers and distribution transformers as power terminals, are equipped with equipment and devices for monitoring and protecting operating conditions. , transmission and recording technologies are all mature; however, on the high-voltage and ultra-high-voltage lines for long-distance transmission, only some pilot studies have been carried out on the detection of some f...
