摘要
为加强避雷器运行管理,对2001—2012年广东电网110～500 kV避雷器设备运行情况进行了统计分析,2001—2012年共发生故障14起,其中以110 kV和500 kV避雷器设备居多,分析认为故障主要是因制造工艺、原材料或零配件质量不良导致的,提出加强验收环节前端管理、有计划地更新老旧避雷器等运行维护措施。
For strengthen management for operation of arrester, this paper statistically analyzes operation of 110~500 kV attesters in Guangdong power grid from 2001 to 2012. There are totally 14 times of faults from 2001 to 2012 among which the 110 kV and 500 kV attesters are in majorities. It considers the main reason for the fault is bad manufacturing process o- riginal materials and installation kits. It proposes to take operational maintenance measures including strengthening front-end management of check and accept link and changing old attesters.
