摘要(Abstract)：

为增强浙江电网高压输电线路的防雷能力,已采取了各种防雷措施,如降低杆塔接地电阻、加强绝缘水平、安装线路避雷器和增加耦合地线等,计算分析采取这些措施对雷击(反击或绕击)跳闸率的影响,提出了高压线路防雷的总体建议。
In order to strengthen the lightning protection capability of high-voltage transmission lines in Zhe-jiang power grid,a variety of lightning measures are adopted,such as reducing tower ground resistance,improving insulation,installing line surge arrester and adding coupling ground wire etc.This paper calculates and analyzes the effect on the lightning trip-out(back striking and shielding failure) rate and puts forward the overall proposals of lightning protection for high-voltage transmission lines.
