摘　　要：我国大多数地区的远程输电线路以220 kV为主,因分裂导线可以抑制电晕放电、减少线路电抗而被广泛使用,但分裂导线粘连是一直需要解决的问题。本文分析了导线粘连出现的原因和影响导线粘连发生的各种因素。以220 kV兰腾双回路输电线路为例,对于发生了导线粘连的线路加装间隔棒后造成的影响进行分析,分裂间隙进行了校验,证明了拆除间隔棒后能够维持分裂导线不发生导线粘连,提出更换导线排列方式和重新放线加大弧垂的方法,解决分裂导线的导线粘连问题。220 kV transmission lines are the main types of long-distance transmission in China,the split conductor is widely used,in order to inhibit corona discharge and reduce line reactance,meanwhile the issue of conductor adhesion splitting remains a persistent challenge that requires resolution.This paper analyzes the causes of conductor adhesion and the factors that affect the occurrence of conductor adhesion.For example,the 220kV Lanteng double circuit transmission line,the impact of incorporating a spacer into the line with conductor adhesion is examined,check the bundle spacing,the split conductor can be maintained without conductor adhesion after the removal of the spacer has been proven,this will be done as two ways as replace the conductor arrangement and extended the arc sag to solve the conductor adhesion problem of double split conductor.
