摘 要:针对气体绝缘开关设备(GIS)击穿放电定位难的问题,提出了一种基于超声波信号检测的GIS击穿放电定位方法。利用传感器采集放电引起的超声波信号,经过无线传输进入上位机进行信号处理,并通过比较不同位置的超声波信号时间先后及超声波幅值大小来实现放电的精确定位。试验结果表明,该法对击穿放电定位准确,简化了排查故障的过程,缩短了GIS调试周期。

Abstract: Aiming at the problem that the disruptive discharge of gas insulated switchgear (GIS) is difficult to position, this paper raised a kind of disruptive discharge position method of GIS based on ultrasonic wave signal test. The sensor was used to collect ultrasonic wave signals caused by discharge and the signals were sent to the upper computer to carry out signal processing through wireless transmission. Time sequence and scale value size of different position’s ultrasonic wave signals were compared to realize accurate position of discharge. The test results show that the method for disruptive discharge position is accurate, simplifying fault checking process and shortening the commissioning cycle of GIS.
Key words: gas insulated switchgear; ultrasonic wave signal; disruptive discharge; accurate position; ZigBee technology
