摘要
对比研究原有的220kV金属氧化物避雷器(MOA)不拆高压引线试验方法后,提出了一种新的MOA不拆高压引线的试验方法;采用了拆引线和不拆引线的方法对220 kV大马沟变电所中马电4941线路避雷器进行了直流试验,并对比分析了其试验数据。结果表明:这种新的试验方法适合于现场的预防性试验。并提出了现场试验的注意事项。
A new test method for MOA without removing the HV lead conductor was proposed as compared with original method for testing 220 kV MOA without removing the HV lead conductor. DC test was performed on #4941 MOA installed at 220 kV Zhongmadian substation with and without HV lead conductor removed, and test data were compared. From the results it is proved that the new test method is suitable for use as a site preventive test; test instruction was presented.
