摘　　要：介绍了关于高压开关柜局部放电检测方法及相关案例,根据局部放电时通常会伴生电磁波、声波、电流行波、热能、发光等各类化学、物理现象,采用暂态地电压检测法(TEV)、超声波检测法(AE)、特高频检测法(UHF),对高压开关柜局部放电进行单项监测或多项综合监测判别和定位。This paper introduces the local discharge detection methods and related cases of high-voltage switchgears.According to various chemical and physical phenomena such as electromagnetic waves,acoustic waves,electric pop waves,thermal energy,luminescence,etc.during local discharge,transient voltage detection(TEV),ultrasonic detection(AE)and ultra-high frequency detection(UHF)are used to carry out individual monitoring or multiple comprehensive monitoring,discrimination and positioning of local discharge of high-voltage switchgear.
