开关柜局部放电检测技术分析及应用

Analysis and Application of Switchgear Partial Discharge Detection Technique

介绍了所使用的几种局部放电检测手段,基于暂态对地电压(TEV)、超声波(AE)、超高频(UHF)检测方法,通过3种方法的联合检测,可以有效检测开关柜局部放电,保障开关柜的安全运行。

Several partial discharge detection methods are introduced, a combined partial discharge detection technique based on transient voltage （TEV）,ultrasonic （AE） and ultra_high frequency （UHF）was proposed ,which provides a data basis for the repairing of switchgear and ensure the safe operation.
