山区超高压输电线路运行中的新型防雷措施及其效果

The New Lightning Protection Measures in the Operation of Mountain Extra High Voltage Transmission Line and Its Effects

本文就目前我国超高压输电线路运行中采用的新型防雷措施进行了阐述,并对其效果进行分析,结合内蒙古地区500kV输电线路的实际运行情况,发现新型的防雷保护措施,尤其是线路避雷器的使用,能够有效地减少输电线路的雷击跳闸事故,但还存在一定的缺陷,需要进一步改进。

This paper expounds the current new lightning protection measures in the operation of extra high voltage transmission line in China, and analyzes the effect. Combined with the practical operation of 500kV transmission line in Inner Mongolia region, it shows that the new lightning protection measures, especially the use of line arrester, can effectively reduce the transmission line lightning trip-out accident, but there are some shortcomings need further improvement.
