摘　　要：笔者以1000 kV淮南—南京—上海特高压交流输电线路工程为背景,结合以往双回路换位塔设计成果,利用三维间隙分析软件,设计了三柱式换位塔、双柱式换位塔以及双回共杆换位塔,并估算了塔重、基础、绝缘子等工程量,通过技术经济比较,得出双回共杆换位塔技术可行、经济合理。最后,推荐1 000 kV双回交流特高压输电线路采用双回共杆换位塔型式。Taking the Huainan-Nanjing-Shanghai 1 000 kV UHV AC double-circuit transmission line project for example,three types of double-circuit transposition tower, i.e. three-pole transposition tower, dual pole transposition tower, and double-circuit transposition on same tower, are designed. The corresponding tower weights and construction quantities of foundation and insulators are estimated. Comparison among the three tower types from technical and economical aspects indicates that the double-circuit transposition on same tower is suitable for the1 000 kV UHV AC double-circuit transmission line.
