500kV耐张塔平衡挂线施工方法探讨

在山区进行张力放线,传统的平衡挂线方法是导线落地压接,同时,安装耐张绝缘子串前需要进行割线、压接,割线长度计算误差、操作人员操作误差等经常影响平衡挂线施工质量。为了解决在山区张力放线受地形限制的影响,江西省送变电建设公司在瀑布沟至东坡东500 kV输电线路工程施工中,摸索总结出导线线长比拟法平衡挂线的施工方法,较好地实现了紧线、挂线一次完成,大大提高了施工工效。

Discussion on Balanced Line-hanging Method of 500 kV Strain Tower

Tension stringing in mountainous area usually adopts the traditional balanced line-hanging method.The installation of strain insulator string calls for some preparation,like wire-cutting,wire-connecting and error calculation,which is of importance for ensuring the quality of line-hanging.Tension stringing is limited by indecent landforms.In order to solve the problem,analogical balanced line hanging method is explored by Jiangxi Power Transmission & Transformation Corporation to improve installation efficie...
