摘要
针对甘肃某供电局氧化锌避雷器(MOA)应用现状,对电站型和线路型MOA结构进行分析,发现110 kV某变电站1号主变压器35 kV侧B相避雷器泄漏电流异常,通过带电检测、停电试验、解体检查,最终确认为受潮故障。
This paper aimed at the MOAs in a power supply bureau of Gansu Province to analyze the structures of line MOA and power station MOA. An example to deal with abnormal on line current detection of 35 kV B-phase MOA in a 110 kV transformer substation was introduced. By analyzing the results of on line measurement, off-line testing and disassembly check, the damp defect of MOA was affirmed in the end.
