电网架空输电线路差异化防雷研究

Research on Differentiated Lightning Protection of Power Grid Overhead Transmission Lines

由于电网架空输电线路通常架设于山地、旷野和丘陵等地区,其相应的雷击概率通常较高,在电网雷害事故中的占比较大,对电网的安全性造成了较大的影响,且严重威胁到供电的稳定性。本文通过分析架空输电线路防雷的重要性入手,对造成雷电危害的主要原因进行分析,并阐述了架空输电线路差异化防雷技术,以供借鉴。

Because the power grid overhead transmission lines are usually erected in mountains,wilderness and hills,the corresponding lightning strike probability is usually high,which accounts for a relatively large proportion of lightning damage accidents in the power grid,causing a great impact on the safety of the power grid,and seriously threatens the stability of power supply.This paper analyzes the importance of lightning protection of overhead transmission lines,analyzes the main causes of lightning damage,and expounds the differentiated lightning protection technology of overhead transmission lines for reference.
