摘要
本文介绍了GIS超声波局部放电带电检测的原理、现场检测方法以及缺陷类型识别方法。结合现场检测案例,通过与典型缺陷特征图谱进行对比,对局部放电类型进行识别。
This paper introduces the principle,the method of field detection and the method of interference recognition for gas insulated switchgear(GIS)ultrasonic partial discharge detection.Combined with the on-site test cases,the partial discharge types are judged by comparing the test spectrograms with the characteristic spectrograms of typical defects.
