一起35kV开关柜绝缘降低的处理分析

Analysis of a 35KV Switchgear Insulation Reduction Treatment

某35kV变电站开关柜开展超声波局部放电检测,发现部分开关柜超声波局部放电声信号明显,对该部分开关柜进行绝缘件检查分析,探讨了该问题的成因,并提出一种解决绝缘件受潮影响方法。

The ultrasonic partial discharge detection was carried out on a 35 kV substation switch cabinet, and it was found that the ultrasonic partial discharge acoustic signal of some switch cabinets was obvious. The insulation parts of the switch cabinet were inspected and analyzed, the causes of the problem were discussed, and a method to solve the influence of insulation parts affected by moisture was proposed.
