单回路转角杆塔中心桩位移的计算

The Center Displacement Cnsideration of Single-loop Corner Tower

在高压送电线路设计中,为避免相邻杆塔承受额外的角度荷载,同时减少相邻直线杆塔悬垂绝缘子串的倾斜角和摇摆角,需将转角杆塔中心桩沿线路转角角平分线方向内角侧或外角侧移动一定的距离。本文对单回路转角杆塔中心桩位移问题进行总结,为送电线路设计和施工提供参考。

In the design of high voltage transmission lines in order to avoid the adjacent tower to bear the additional load angle, while reducing the adjacent tower suspension insulator strings straight tilt angle and swing angle needs to be the center of the corner towers along the road comer pile interior angle bisector direction side or exterior angle side moves a certain distance. In this paper, single-loop pile displacement of the center of the corner tower summarize issues and provide reference for the design and construction of transmission lines.
