微波塔引发配电线路雷电事故的分析

The Analysis of Distribution Lines Lightning Accident Caused by Microwave Tower

通过对微波塔易遭雷击以及微波塔引发配电线路雷电事故进行原因分析,阐述了对配电线路造成的后果和防范措施.通过案例事故,论述产生直击雷和感应雷的原因,同时论证两种雷电过电压对配电网络的危害和幅值大小,最后论述了防范此类事故的有效措施.实践表明:采取必要的防雷措施,是避免雷击,降低雷击危害的有效手段.

Through the analysis of the microwave tower stuck by lightning, as well as a microwave tower can trigger distribution lines occur lightning accidents, and explaining the consequences of the distribution lines and precautions. From two accidents, this paper discusses the reasons for inducing direct lightning stroke and lightning, then, demonstrates the magnitude of two kinds of lightning over voltage and the damage to the power distribution network. Finally, this paper discusses the effective measures to prevent such accidents
