GIS特高频和超声波局放检测技术现场综合应用

Comprehensive Application of Ultrasonic and Ultra High Frequency Method on Partial Discharge Detection in GIS

特高频/超声波局部放电测量技术已成为运行GIS设备局部放电监测的重要手段。本文介绍了特高频和超声波局部放电测量的原理,采用2种局部放电检测手段对有异常局放信号的GIS设备进行了检测和分析定位,并结合局部放电检测结果,对GIS设备进行了现场解体。

UHF/uhrasonic partial discharge measurement techniques have become an important means of partial discharge monitoring in running GIS equipment. The paper first introduced the princi ple of UHF and ultrasonic PD measurement, and then integrated the two detection means to detection and analysis of positioning on the GIS equipment with abnormal signal. Finally, according to partial discharge lest results, the GIS equipment was disintegrated in the field.
