摘　　要：局部放电试验对干式绝缘电气设备存在的弱点或缺陷具有很好的检测作用,但常常因为干扰的影响,使测试无法达到满意的效果。文章阐述了35 kV固体绝缘电流互感器在进行局部放电试验中,使用滤波电源。平衡法接线等抗干扰措施后,取得了较为满意的测试效果。Partial discharge test have good detection effects the weak points and defects of dry insulation inductor, but the test often couldn＇t attain the satisfied purpose because of the interference. This paper presents 35 kV solid insulation current transformer partial discharge test, using the filter power source, the balanced connection and other anti - interference measures are utilized. Fulfiled the satisfied effects.

关 键 词：局部放电试验 干扰 滤波电源 平衡法
