架空输电线路防雷措施探讨

Overhead Transmission Line Lightning Protection Measure

长期以来,雷击引起的输电线路跳闸对电网安全稳定运行构成了较大的威胁,迫切需要提高输电线路抵御雷电的能力,降低雷电造成的损失和影响。文章介绍了雷击的种类,分析了输电线路遭受雷击的主要原因,并提出了防雷措施。

For a long time, the transmission line trip caused by struck by lighting is a big threat to the sta- bility and safety of power grid. It＇s urgent to improve the resistance ability of transmission line to lighting stroke and as far as possible to reduce the loss and influence caused by lighting. This paper introduces the types of lighting stroke and analyzes the main reasons for the transmission line being struck by light- ing. Meanwhile, some lighting protection measures for the transmission line are proposed.
