摘要
介绍了开关柜带电检测方法及分析判据,通过超声波检测、特高频检测以及暂态地电压3种方法,以变电站实例阐述了开关柜悬浮放电、沿面放电、电晕放电3种放电类型,具有推广和借鉴意义。
This paper introduces the detection methods and analysis criteria of switchgear on line.Through three methods of ultrasonic detection,UHF detection and transient ground voltage,three discharge types of switchgear suspension discharge,surface discharge and corona discharge are described with an example of substation.
