Description

technical field [0001] The invention relates to an insulator flashover fault location device and a location method. Background technique [0002] In the existing high-voltage transmission system, the insulator is an essential part. It isolates the high voltage from the ground and mechanically stretches the transmission line, which plays a role in supporting the transmission line and preventing the current from returning to the ground. Along the transmission line, there are a large number of insulators, many types, and a wide distribution. Flashover grounding faults such as pollution flashover, wet flashover, and ice flashover of insulators often occur. Once an insulator flashover occurs, the circuit breaker will open to cut off the flashover current, and then reclose. If reclosing is unsuccessful, it is necessary to quickly locate the faulty insulator and deal with it in time to ensure reliable power supply. Manual line inspection can locate flashover insulators, but the ...

Problems solved by technology

Due to the large number of line insulators, the cost of this patent is too high, and the insulator flashover fault is not intuitive

Moreover, the microelectronic circuit used in the patent is susceptible to interference from corona and flashover transient strong electric fields at the operating site. In order to enhance the reliability of the entire system, the electromagnetic compatibility design of the system is complicated and costly
