摘要
介绍了局部放电超声波检测法的基本原理,对35 kV充气开关柜局部放电超声波检测的试验结果做出了具体分析,诊断出断路器气室和电缆出线柜之间存在屏蔽松动现象,并提出整改建议。
The paper introduces the basic principle of partial discharge ultrasonic detection method,and analyzes the test results of partial discharge ultrasonic detection method for 35 kV gas-filled switchgear in detail,finally founds a shielded loose between the circuit breaker chamber and cable outlet cabinet,and puts forward the upgrading measures.
