摘要

笔者对500 kV双回路直线小转角塔开展了设计研究

通过计算绝缘子串摇摆角

根据绝缘子串设计结果

在计算了小弧垂、水平线距后

绘制了杆塔间隙圆

确定了直线小转角塔塔头尺寸。还对将500 kV双回路直线小转角塔与同等条件下的耐张塔进行了对比

在塔重、绝缘子和金具等方面

500 kV双回路直线小转角塔具有良好的经济性。

Abstract

In this paper

it analysis the characteristics of 500 kV double circuits small-angle suspension tower.First of all

the swing angle of the insulator string is calculated;Then

according to the parameter of the insulator string

the clearance safety scope is drawing to decide the dimension of the tower. Compared with the tensile tower at weight

insulator and fittings

under the same conditions

the 500 kV double circuits small-angle suspension tower has better economy.
