摘　　要：利用有限元分析了220 kV同塔双回钢管塔和同尺寸复合材料杆塔附近电场分布,并比较了2种材料杆塔线路对周围环境电场的影响。分析了杆塔处地面电场强度,对比了2种材料杆塔沿线路走廊纵向和沿走廊轴向2个路径的沿线电场分布。研究结果表明,复合材料杆塔在一定程度上改善了杆塔附近的电场环境。With the finite element analysis,this work analyzes the electric field distribution of 220 kV transmission steel tower with double-circuit and composite-insulated transmission tower with the same size,and compares the effect of two-type transmission tower on the electric field of surroundings.Also it analyzes the ground electric field intensity around the pole,compared the vertical electric field distribution along transmission line of the two-type transmission tower and also compares the axial field.The results indicate the composite material tower can improve the environment of electric field near the transmission line.
