摘　　要：介绍了所使用几种局部放电检测手段及其特点,其彼此间有互补性。对一起35 kV开关柜放电缺陷的发现、复测和诊断过程做了介绍,并指出局部放电普检对状态检修的重要性,开关柜常见放电部位,应加强对间歇性放电源的检测。Several partial discharge detection methods are introduced. These methods can compmment eacn omen. The discovery, remeasuring and diagnosis of the partial discharge faults in a 35 kV switch cabinet are discussed. Moreover, the importance of partial discharge detection to condition maintenance of the switch cabinet is stressed, and the usual partial discharge spot in switch cabinet is pointed out. The sources inducing intermittent partial discharge should be paid much more attention to.
