针对山区输电线路防绕击雷性能的探讨
Shielding Failure Protection Research of Transmission Line in Mountain Area
摘要
绕击是超高压、特高压输电线路雷击跳闸的主要原因，山区绕击跳闸率计算相对平原更为复杂。通过分析，在地面倾角和风速情况下对EGM电气几何模型进行了修正。根据实际算倒探讨了影响山区输电线路绕击率的不同因素，重点分析了因雷电先导入射角以及地面倾角变化对绕击率的影响。
Abstract
Shielding failure is the main cause of lightning flash-over of EHV transmission lines and UHV transmission lines, The calculation of SFFOR in a mountainous area is more complicate than that in the plain. Through analysis, the parameters of EGM electro-geo
