同塔多回高压输电铁塔结构设计及应用

Design and Application of Multi-Circuit High-Voltage Transmission Tower Structures with the Same Tower

我国电力系统发展中,局部地区面临高压直交流输电线路走廊交叉问题,可采取同塔多回高压输电架线模式,解决匮乏的线路走廊资源情况,需要优化设计输电铁塔结构,保证铁塔可靠性。文章以山东菏泽巨野彭越(段庄)220kV变电站110kV送出工程为例,简要分析同塔多回高压输电铁塔建设要求及结构设计,并以此为基础,提出实际应用措施,从而为相关工作者提供参考。

In China’s power system development,local areas are facing high-voltage straight and alternating current transmission line corridor crossing problem.The same tower multi-circuit high-voltage transmission overhead mode can be used to solve the scarcity of line corridor resources.It is necessary to optimize the design of transmission tower structure,and ensure the reliability of the tower.This paper takes 110 kV transmission project in Heze Juye Pengyue(Duanzhuang)220 kV substation as an example,briefly analyse the same tower multi-circuit high-voltage transmission tower construction requirements and structural design,and accordingly proposes the practical application measures,so as to provide reference for the relevant workers.
