摘要
通过对一起500 kV氧化锌避雷器由受潮导致上节避雷器击穿故障的解体分析,讨论了运行电压下总泄漏电流和阻性电流与电阻片受潮片数的对应关系,为今后避雷器的运行维护提供理论经验。
Based on the breakdown analysis of a 500 kV zinc oxide arrester under dampness, the corresponding relationship between total leakage current and resistive current under operating voltage and the number of damp patches of resistors is discussed, which provides theoretical experience for the operation and maintenance of arresters in the future.
