| 摘 要： | 采取200 kV直流高压发生器与RCD型阻性电流测量仪,通过对金属氧化锌避雷器进行直流泄漏测试与带电测试全电流与阻性电流的实验,得出了金属氧化锌避雷器停电直流泄漏试验是发现避雷器受潮最有效的方法,而带电测试金属氧化锌避雷器全电流与阻性电流只能在单节避雷器中有效,对于220 kV以上两节组装避雷器是无效的。

| Abstract: | Using the 200 kV high-voltage DC generator and RCD type resistive current measuring instrument,through carrying out DC leakage testing,on-line detecting full current and resistive current on MOA,the most effective method,which can find out arrestor damp,has been obtained.The method is MOA DC leakage testing in blackout.Moreover,the charged detecting MOA full current and resistive current only be effectively in a single arrester,for 2 assembled arrester above 220 kV is invalid. |
