摘要(Abstract):
针对一起220 kV避雷器泄漏电流带电检测数据异常案例,结合红外测温以及停电后的直流泄漏电流测试,最终发现并验证了该泄漏电流异常的原因是避雷器表面污秽,避免了对设备的过修。结合此次疑似故障的原因分析,提出了对此类问题的解决方案以及避雷器状态检测时应注意的问题。
There is data exception in live detection of leakage current of 220 kV arrester. By infrared temperature measurement and DC leakage current test after power cut, it is finally detected and proved that the abnormal leakage current is caused by defilement on arrester surface, hence unnecessary maintenance of equipment is prevented. By cause analysis on the suspected fault, the paper proposes solutions to such problems and precautions in arrester detection.
