避雷线分流装置的制作与应用

The Production and Application of Ground Wire Shunts

本文作者根据多年来的实践经验和研究,发现架空输电线路遭受雷击引起线路跳闸时存在薄弱环节,并针对性地采取防范措施,改进了避雷线与杆塔的连接方式,采取加装分流线将避雷线直接连接到杆塔上,经过长时间的实践证明,有效地提高了雷电流的泄导水平,降低了线路的雷击跳闸率。

Based on years of practical experience and re-search,the author of this paper points out that pre-ventive measures can be taken against the lightning trip-outs of overhead power transmission lines. Long-term practiee has proved that when the ground wire is directly connected to the tower with a shunting wire,lightning eurl＇ent will be more effi-ciently guided to discharge so that the lightning trip-out rate will be reduced.
