摘要
介绍了开关柜局部放电带电检测常用的两种方法,对某110 kV变电站35 kV开关柜暂态地电压检测和超声波检测过程中出现的异常数据与放电信号进行了综合分析,通过两种方法结合判断出异常开关柜的放电类型,并进行了验证与有效处理。
This paper introduces two methods commonly used in the detection of live discharge of switchgear. The abnormal data and discharge signals in the transient voltage detection and ultrasonic detection of a 35 kV switchgear in a 110 kV substation are analyzed synthetically. The discharge type of the abnormal switchgear is judged and effectively treated.
