Problems solved by technology

If the gap no longer discharges, it means that the insulation performance is restored, and it also means that the insulation performance of the spark gap can be restored under the conditions of greater than the estimated insulation recovery time and less than the applied voltage, but this range is too wide. If you need more accurate data, it is necessary to repeatedly debug the applied voltage and time interval; the detection efficiency is particularly low, and the detection cost is high; Time arcing has a great influence on the insulation performance of the gap, and the obtained insulation recovery voltage data is not accurate

Abstract

The invention provides a spark gap insulation recovery voltage detection device and a detection method thereof. The device comprises a current generation apparatus, wherein the output end of the current generation apparatus is in series connection with a controllable switch K1 and then is connected in parallel with a spark gap, and is used for outputting a current to the spark gap; a voltage generation apparatus, wherein the output end of the voltage generation apparatus is in series connection with a controllable switch K2 and then is connected in parallel with the spark gap, and is used for outputting a voltage to the spark gap; a voltage-dividing apparatus which is connected in parallel with the output end of the voltage generation apparatus, and is used for detecting the output voltage of the voltage generation apparatus; and a control circuit which is connected with the voltage generation apparatus, and is used for detecting an alternating current of the output end of the voltage generation apparatus and the output voltage of a voltage adjuster, and controlling the on / off of the voltage generation apparatus according to the alternating current and the output voltage. According to the invention, a series of effective data points can be obtained in each detection process, and the device and method reduce the detection cost, and improve the detection efficiency.

Description

technical field [0001] The invention relates to a detection device and a detection method thereof, in particular to a spark gap insulation recovery voltage detection device and a detection method thereof. Background technique [0002] The China Electric Power Research Institute applied the series compensation device to the UHV demonstration project for the first time. Although the current performance parameters of the series compensation device can meet the needs of the project, with the continuous development of the UHV series compensation technology, follow-up projects will not be able to use the series compensation device. In order to improve the rated voltage and rated current of the series compensation device, it is necessary to conduct in-depth research on the performance of the UHV series compensation device. [0003] The series compensation device is generally put into use on the line after the line fault is cleared, but sometimes in order to improve the stability of...
