摘　　要：为分析500kV超高压输电线路下的电场分布问题,采用电磁场分析软件Ansoft Maxwell建立了500kV超高压水平排列输电线路在不同地形条件下的二维模型。分析了凹形地面、凸形地面、地面凹凸程度,及地形所处位置变化对输电线路电场分布的影响,并探讨了同一水平高度由于地形变化带来的电场变化,为非平原地区输电线的电场研究提供了借鉴。This paper used the Ansoft Maxwell to establish two-dimensional models of the 500 kV EHV horizontal arrangement transmission line under different types of terrain to analyze the electric field distribution.It analyzed many influencing factors to the electric field distribution of transmission lines,such as concave landforms,convex landforms,the degree of concavo-convex,and the alteration of terrain.In addition,it discussed the electric change caused by the terrain changes on the same level.This research provides a study reference to the electric field of transmission lines in uneven terrain areas.
