摘要(Abstract):

输电线路雷击跳闸与环境因素密切相关,对雷电参数、地形、地貌等因素之间的相关性进行了研究,指出这些因素与雷击跳闸的相关规律,提出了输电线路雷击跳闸环境风险评估的相关因子权重值,可较全面地反映线路杆塔所处位置雷击风险的大小。
The lightning trip-out on transmission lines is closely related to the environmental factors.This paper studies the correlation among lightning parameters,topography and landform and it points out the regular between the factors and lightning trip-out;it proposes the weight of environment factors for risk assessment of lightning trip-out on transmission lines,comprehensively reflecting risk significance of lightning at the location of poles and towers.
