摘要
在变电站日常巡检、例行试验、缺陷检查定位等工作中,经常使用到带电测试技术,最常用的带电测试技术是红外测温和局部放电测试。本文重点介绍了在某220kV变电站带电测试工作中发现的两起缺陷,其中红外测温技术在一起110kV电容式电压互感器的故障分析中的应用,超声波检测法和暂态地电压检测法在一起35kV开关柜局部放电缺陷中的应用。
In the daily inspection,routine test,defect inspection and positioning of substations,etc.Live line Detection technology is often used,the most commonly used Line line Detection is infrared temperature Measurement and partial discharge test.This paper focuses on two defects found in the Line line detection of a 220kV substation.Application of infrared temperature measurement technology in malfunction analysis of 110kV capacitive voltage transformer,and application of ultrasonic detection method and transient ground voltage detection method together in partial discharge defect of 35kV switchgear.
