开关柜局部放电检测典型案例分析

Classic Case Analysis of Partial Discharge Based on Switch Cabinet

近年来,台州供电公司对所管辖的变电站每年都会进行带电检测工作,采用特高频局放测试、超声波局放测试、红外测温、开关柜暂态地电压测试等作为常用的带电检测手段。本文将具体分析开关柜局部放电检测的案例,以供相关人员参考。

In recent years,Taizhou Power Supply Company will carry out live detection for the substation under its jurisdiction every year.UHF partial discharge test,ultrasonic partial discharge test,infrared temperature measurement,switch cabinet transient ground voltage test,etc.are commonly used as live detection means,which are used in the annual live detection.This paper will analyze the case of partial discharge based on the switch cabinet for future reference.
