| 摘 要： | 架空绝缘导线存在两种雷击断线形式。工频续流建弧与否决定绝缘导线是否断线,击穿点的与绝缘子横担的距离决定断线形式。防止雷击后工频续流建弧是解决配电线路雷害的主要方法。配电线路避雷器基本要求是:免维护;运行状态在巡视时可一目了然;安装时不与导线直接相连;能与各种绝缘子配合;损坏时不影响线路供电;可带电拆卸。

| Abstract: | The overhead insulated conductor is able to be broken by lightning strike in two ways,the power-flow current arcing decides the insulated conductor broken or not,the distance between the breakthrough point and insulator cross arm decides the way of breakdown.To avoid power-flow current arc is the key solution to prevent distribution line from damaged by lightning strike.The basic requirements of distribution line arrester are: Maintenance free;outer visual inspection;no direct link to conductor when installing,good compatibility with different kinds of insulator,no affection to conductor operation when breakdown,online removal. |
