摘要:
金属氧化物避雷器分立式底座往往在运行一段时间后,会出现底座绝缘电阻显著下降的问题,底座绝缘缺陷将对在线监测和避雷器动稳定性造成影响。以某变电站110kV金属氧化物避雷器分体式底座绝缘缺陷为例,通过解体检查和试验数据对比分析,认为金属螺栓锈蚀和表面污秽是分立式避雷器底座绝缘不良的主要原因,并提出了分立式底座绝缘不良的处理方法。
Abstract:
After operation for a period of time there will be a significant reduction in insulation resistance problem on the separate base of metal oxide surge arrester, base insulation defects will affect the on-line monitoring and the stability of the arrester. Taking a 110 kV metal oxide surge arrester separate base insulation defects as an example, through the decomposition inspection and test data comparative analysis, indicating that the metal bolt corrosion and surface contamination is the main reason to cause the insulation fault of the separate arrester base, and proposed the treatment method.
