摘要
由于变电站的氧化锌避雷器数量众多,电压互感器二次端子箱和避雷器的距离相对较远,部分测试设备体积较大,接 线繁琐,往往需要较多工作人员配合完成带电测试,导致测试工作效率低,工作强度大.我们拟研制一套针对避雷器带电测试的 便携式测试仪表,既能准确测试避雷器的泄漏电流和阻性电流的数值,又体积轻小,便于携带,从而减轻劳动强度,节省人力,极大 地提高氧化锌避雷器带电测试的工作效率.
Due to a large number of zinc oxide arrester（ M0A ） in the substation, the long distance between Voltage transformer seconda-ry terminal box and M0A,the huge volume of some testing equipment and the complex wiring,the live testing needs many personnel. In this case,the efficiency of testing world will become low and the world intensity becomes larger. We plan to develop a set of portable testing de-vice. Witli this device,we can get tlie leakage current and resistive current of MOA accurately. Besides,the equipment is smaller and lighter.Finally,we achieve the goals of reducing labor intensity and improving the work efficiency.
