摘要
针对2006年6月华北电网输电线路雷击故障偏多的情况,从设计、基建及运行角度进行了综合分析,并结合雷电定位系统运行情况对输电线路进行了分级,确定了一系列反事故措施,对于线路开展防雷工作具有指导意义。
Relatively more lightning failures happened on the transmission lines of North-Chian Power Grid in July, 2006. Aiming at this phenomenon, comprehensive analysis was made from the angles of design, foundation construction and operation. Based on the results of the lightning locating system test ,transmission lines are eompartementalized to several classes. Countermeasures are also given to guide the works of antilightning.
