摘　　要：1000kV特高压交流双回路输电线路的换位设计复杂,分析了三柱换位设计的优缺点,针对其占地多、跳线设计复杂、施工要求高的特点,研究了一种新型双柱换位塔。介绍了双柱换位塔的跳线布置方式、电磁环境、防雷水平以及跳线金具串的设计,并将其与三柱换位塔在走廊占地、塔重等方面进行综合经济指标比较,结果表明双柱换位塔更具优越性和实用性。As the transposition design of 1 000 kV UHVAC double-circuit transmission line was complicated,the advantages and disadvantages of three-column transposition tower were analyzed.According to the disadvantages of three-column transposition tower,which were more occupied land,complicated jumpers and high construction requirements,a new type of tower named double-column transposition tower was researched.The jumpers＆#39; arrangement,electromagnetic environment,lightning protection level,jumper fitting strings＆#39;design of double-column transposition tower were introduced. Compared with the three-column transposition tower in corridor area,tower weight and other comprehensive economic indicators,it shows that double-column transposition tower has more superiority and practicability.
