| 摘 要： | 电力机车大气过电压保护主要是在网侧设置金属氧化物避雷器，检修规程要求应定期对避雷器进行预防性试验，氧化锌避雷器的等效电路为非线性电阻与非线性电容的并联，如何从物理结构上不可分割的非线性阻容并联的电路中准确分离出阻性电流，是该试验台研制的重点。

| Abstract: | Metal oxide an＇ester on line - side are used for Atmospheric overvoltage protection of electric locomotives. According to locomotive inspection and repair regulation, regular preventive test for arrester should be carried out. Equivalent circuit of zinc oxide arrester are paralleled of nonlinear resis- tance and nonlinear capacitance, development emphasis of the test - bed is how to separate resistance current from nonlinear resistance - capacitance paralleled circuit which can＇t separate in physical structure. |
