摘　　要：我国目前运行的超高压交直流线路的电压等级为500kV及750kV。对500kV线路的杆塔荷载规划有较丰富的工程设计经验。特高压输电线路是迄今为止世界上最高电压等级的输电线路,在我国还是空白。现有的杆塔荷载的规划能否适应特高压输电线路尚需进一步研究。文章对特高压输电线路的杆塔荷载规划及经济档距等进行分析研究,结合工程的特点,确定特高压输电线路合理的经济档距及经济塔高,以降低特高压输电线路的工程投资。The voltage levels of the UHV AC/DC transmission lines currently used in China are 500 kV and 750 kV. Although experienced in 500 kV line pole and tower load planning, the UHV transmission line, which is the highest voltage class in the world, is totally new to China. Combined with engineering characteristics, this paper analyzes the UHV transmission line pole and tower load planning and economical spans to determine rational and economical spans as well as tower height and reduce the project cost.

关 键 词：杆塔荷载规划 经济档距 优化排位
