1000kV淮南-南京-上海特高压交流双回换位塔研究

摘要

本文以1000kV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，得出双共杆换位塔技术可行，经济合理。最后，推荐1000kV淮南-南京-上海高压交流输电线路工程采用双回共杆换位塔型式。%Based on the 1000kV UHV AC Double-circuit Huainan-Nanjing-Shanghai transmission line project,the paper designing three type of Double-circuit Transposition Tower with reference to some research results of double-circuit transposition towers.The paper also estimated the quantities of the transposition towers on tower heavy, foundation and insulators.it is show that double-circuit transposition on same tower gets more advantage by the analysis of technical and economic comparison.At last,the paper recommend that double-circuit transposition on same tower as the optimization type on the 1000kV UHV AC Double-circuit Huainan-Nanjing-Shanghai transmission line project.
