摘要
介绍广东线路避雷器的安装应用规模,通过避雷器动作率和保护有效性、终端避雷器加强侵入波保护、中间避雷器减少雷击跳闸等运行实例指出其防雷效果明显。分析线路避雷器运行故障、典型缺陷和保护失效案例,并介绍运行检测情况、指出存在的问题。建议推进线路避雷器的防雷应用,并加强巡视、维护,规范和开展线路避雷器抽检试验,提高线路避雷器应用水平。
Installation scale of line arresters in Guangdong was introduced, and its clearly protection effects was indicated by operation instances such as action rate and protection validity, inrush wave protection of terminal arrester, reduction lightning trip-outs of middle arrester. Operation faults, type defects and protection invalidations were analyzed, the operation examinations states was introduced and the existent problems were pointed out. It is proposed to promote the application of line surge arrester lightning protection, and to strengthen the inspection, maintenance, standards and carry out sample tests of line arrester, to improve the level of line arrester applications.
