220kV输电线路双分裂导线粘连成因及处理方法

近年来．广东省广电集团有限公司东莞供电分公司输电线路双分裂导线粘连故障时有发生．为此．对导线粘连的原因及其处理方法进行了详细的分析．提出单独增大粘连档同相双分裂导线子导线间距的处理方法。该方法较为简单、省时．在整个耐张段．除粘连档外．其它档子导线间距符合规程要求时．可以消缺。

Cause analysis and disposal of 220 kV twin bundled line adhesion

The adhesion of 220 kV twin bundled transmission lines of Dongguan Power Supply Branch,GPG often occurred in recent years.This paper detailedly analyzes the cause of the conductor adhesion,and presents a solution of solely increasing the same-phase bundle spacing in the adhered span without changing the original values of other spans in the whole strain section.The method is simple and labor saving,and is of active significance to the safety of power grid.
