摘　　要：高压直流双回塔共有八种极导线排列方式。通过仿真计算,分析比较它们的地面合成电场强度和耐雷水平,选出最合理的极导线排列方式,其地面合成电场强度水平为各方式中最低,且耐雷水平能完全规程要求。There totally exists 8 pole conductor disposition schemes in a double circuit HVDC tower. Through simulation, analysis and comparision on the synthetic electric field intensity on the ground underneath and the lightning withstand level resulted are made, the most reasonable pole conductor disposition scheme is selected with the lowest ground electric field intensity and its lightning withstand level conforms entirely the requirements of the technical code.
