摘要
目前采用的线路型避雷器多为绝缘子间隙避雷器。运行单位在安装线路避雷器时主要考虑的是避雷器的电气性能,很少对避雷器的安装形式和运行状态下的受力情况进行分析,以至运行中出现掉串现象。例举了一起线路型避雷器断串缺陷,通过计算分析得出断串的原因,并提出了避雷器安装的防范措施。
The currently-used lightning arresters for transmission line are mostly insulator gap arresters.During the installation of lightning arrester,the main concern focuses on its electrical performance,and little attention is paid to its installation mode and operating force analysis,consequently the faults of arrester disconnection occur in operation.This paper exemplifies the disconnection fault with one case of transmission line surge arresters.By calculation the disconnection reasons are analyzed,and preventive measures during lightning arrester installation are recommended.
