摘　　要：介绍了一种利用分段加压和压电薄膜传感器相结合的气体绝缘金属封闭开关设备(GIS)故障放电点定位方法,并结合某变电站110 k V GIS设备交流耐压试验为例,给出了使用该定位方法对放电点的排查定位过程,试验结果表明,该定位方法可以实现现场GIS设备交流耐压发生击穿后故障点迅速准确地定位。Introduction was made to a kind of faults discharging point location method of gas-insulated metal-enclosed switchgear (GIS)combining subsection forcing with piezoelectric film sensor. Taking the alternating current (AC) voltage withstand test of 110 kV GIS incertain substation for example, this paper gave the checking location process for the discharging points with this location method. The testresults show that this location method could realize faults point location rapidly and correctly after the AC voltage withstand of GIS breakingdown.
