摘　　要：论述了通过合理接线实现220kV金属氧化锌避雷器(MOA)不拆高压引线预防性试验的原理和方法,将实测容城2#变220kV桥MOA的绝缘电阻、直流1mA电压U1mA及75%U1mA电压下泄漏电流的结果与拆高压引线试验数据对比,证明该法准确、高效、切实可行。The preventive test on 220 kV MOA with high voltage lead through proper wire connecting was studied. The insulation resistance, leakage current under 1 mA DC voltage and 75% of 1 mA DC voltage of a 220 kV bridge MOA were measured. The results were compared with those test data got from the MOA without high voltage lead and showed that the method with high voltage lead is pre- cise, efficient and feasible.
