摘　　要：以 2 2 0kV同塔双回线路为例 ,利用等效电荷法计算其线下空间电场强度的分布模型 ,得出其空间分布呈椭球状的特点 ,由此给出该电压等级送电线路的电磁防护安全区为距边相导线垂直距离大于 6m的空间区域 。In this paper, the distribution of power frequency electric field intensity under 220 kV double circuit transmission lines are calculated by using charge equivalent method, and then the ellipsoid characteristic of space-distribution is analyzed by mathematical method, The safe area for electromagnetic radiation protection is the space whose perpendicular distance to side-phase line is excess of 6 m. The analysis and calculating results will be valuable to solve similar problem for other voltage level lines.
