摘　　要：±800kV楚穗直流输电工程重冰区段部分耐张塔采用分体式耐张塔,在更换极1跳线串时不能采用更换普通"V"串方法,为此研究"V"型跳线绝缘子串更换方法,以提高维护特高压直流线路水平。In the heavy ice section of the ±800 kV Chuxiong-Suidong UHVDC Transmission project,split strain towers are partially used.The method of replacing the normal V string cannot be used to replace the pole 1 jumper string.Therefore,the replacement method for V string jumper wire insulator is studied,to improve the maintenance level UHVDC transmission lines.
