| 摘 要： | 特高压杆塔横担的伸出长度及受力远大于普通杆塔横担，同时横担主材和斜材的受力和计算长度值分别小于塔身主材和斜材，目前国内对特高压横担选材结果不尽一致。以1 000 kV皖电东送输电工程同塔双回路耐张钢管塔为例，对钢管塔横担主材及斜材选用角钢或钢管进行了计算分析比较，研究了横担选材原则，为今后工程设计提供参考。

| Abstract: | The cross arm＇s extension length and stress of UHV tower are much more than those of ordinary tower,and the main-leg and diagonal member＇s stress and effective length of the cross arm are both less than those of tower,leading to the difference in UHV cross arm selection in China.In the case of the strain steel tubular tower in Anhui-to-East two-circuit UHV lines built on one tower,the selection of angle steel or steel tube was investigated for main-leg and diagonal member of the cross arm.This paper presents a selection method for cross arm,which can provids references for engineering design. |
