500kV金属氧化物避雷器的运行状态带电诊断

Charged state diagnostic for 500kV metal oxide arrester

针对500kV电网金属氧化物避雷器运行状态劣化缺陷的诊断,综述该避雷器运行状态带电诊断方法,基于一避雷器测试数据及解体情况对其运行状态进行理论研究及试验数据分析,提出目前现行管理规程/标准中关于带电诊断方法存在的问题,并给出改进方案,从而更有效地指导现场设备安全稳定运行。

According to the deterioration defect diagnosis for 500kV metal oxide （MOA）,this paper comprehensive analyzed the charged state diagnostic methods for 500 kV MOA.The MOA charged state was theoretical analyzed and experimentally tested based on the testing data and disintegration condition of one MOA.Then some problems were proposed on the current management rules/standards for the charged diagnostic methods,as well as some revised proposals were presented.They can effectively direct the safely and stably operation of power equipments,such as MOA.
