摘要
目前,GIS局部放电检测技术已广泛应用到GIS检测。简述了GIS内部发生局部放电主要有自有颗粒放电,悬浮电位放电,电晕放电、绝缘支柱绝缘下降等GIS常见的典型局部放电故障,针对以上GIS内部典型故障,给出了可检测GIS局部放电特高频检测和超声波检测的两种常用检测方法,利用上述检测方法可对局部放电类型进行判断,对放电源进行定位,进而可准确找出故障点。
At present, the GIS partial discharge detection teehnol0gy has been widely applied to the GIS. This paper briefly describes the types of partial discharge in GIS, such as free particle discharge, suspended potential discharge, corona discharge, insulation support discharge ,and for the above cases, this paper gives two kinds of common detection principle of GIS partial discharge： UHF partial discharge detection and ultrasonic partial discharge detection, the detection methods can be used to judge the type of partial discharge, locate the discharge power, and find out the fault point accurately.
