摘要

局部放电(PD)检测技术可以有效发现开关柜的绝缘故障，保证设备的可靠运行。本文介绍了利用超声波和超高频局部放电联合检测技术发现隔离开关柜混合放电缺陷的实例。对缺陷原因进行了分析，验证了局部放电试验结果的有效性，并提出了检修建议。

Defect Analysis Of An Switch Cabinet With Mixed Type Partial Discharge

The insulation fault of switch cabinet can be effectively found by partial discharge (PD) detection technology to ensure the reliable operation of equipment. In this paper a case of mixed discharge defects of isolating switch cabinet was introduced, which was discovered by using ultrasonic and UHF partial discharge combined detection technology. The defect causes verify the validity of the partial discharge test results and some suggestions for repair and maintenance were put forward.
