摘要(Abstract):
提出了一种将暂态地电压和超声波检测技术相结合的开关柜局部放电带电检测方法,并应用于一起35 kV开关柜异响分析中,通过试验数据的分析,找到异响部位。对比实际的停电检查结果,验证了该方法进行开关柜局部放电检测的准确性。
An energized test method of partial discharge for switchgears based on the combination of the Transient Earth Voltage(TEV) and ultrasonic detection technologies is proposed.The method is used to analyze the abnormal sound in a 35 kV switchgear.Through the analysis of the test data,the fault position is located.The accuracy of the method is verified by comparison to the result of actual outage inspection.
