摘　　要：介绍了目前广东电网使用的配网用避雷器的类型、安装方式,并对广东电网配网10 kV避雷器的故障模式进行详细调研统计,对现场获取的部分典型避雷器与生产厂家相同型号的未使用避雷器进行对比试验分析,分析了目前广东地区配网用避雷器的故障原因及安装和使用中存在的问题,主要为电阻片规格、密封性、结构、安装方式、接地电阻等方面不符合要求,导致广东电网配网避雷器故障较多。笔者提出应提高电阻片规格,改进密封性能、结构设计及安装方式,以提高广东电网的供电可靠性。This paper introduces the type and installation mode of 10 kV arresters in Guangdong power grid, and investigates their failure modes.Comparative tests were conducted for the failed 10 kV arresters and the new ones,and the failure causes and installation problems of the 10 kV arresters in Guangdong power grid were analyzed. The results indicate that the resistance card specification, sealing performance, structure,installation mode, and earth resistance do not meet the requirements, which leading to frequent faults with the arresters in Guangdong power grid. Some corresponding suggestions are offered to enhance the reliability of the Guangdong power grid.
