摘要
本文介绍了GIS特高频局部放电带电检测的原理、现场检测方法以及干扰识别方法。结合典型案例,通过与相邻盆式绝缘子的单周期图谱对比,配合PRPD图谱以及峰值检测图谱,对局部放电类型进行判断。
This paper introduces the principle,the method of field detection and the method of interference recognition for GIS ultra-high frequency partial discharge detection.Combined with a typical case,the partial discharge types were judged compared with the online single cycle diagram,the phase resolved partial discharge and peak hold diagram of the adjacent basin insulator.
