摘要
介绍了超声波检测和超高频检测在GIS设备局部放电带电检测中的应用,通过一起CT气室局放量数值偏大故障分析,2种检测方法优势互补,诊断出GIS存在悬浮电位引起的较严重局部放电,判断GIS罐体内有异物,并提出了整改建议。
The paper introduces the ultrasonic testing and ultrasonic frequency detection in the application of partial discharge detection for GIS equipment. The two detection methods＇ completes each other, diagnoses GIS existing floating potential to cause more serious partial discharge, thus finds a foreign object in GIS, and some rectification opinions are proposed.
