摘 要:为提高输变电领域的快速复电效率和扩展抢修塔适用范围,设计了我国首基自立式铝合金门型抢修塔1C1W6-JZQL,并在大风、断线、安装、运行等7个工况下对真型塔进行试验。试验结果表明:1C1W6-JZQL抢修塔在7个工况的荷载加载试验中,抢修塔各部构件未发生明显弯曲和扭转变形,说明杆塔整体结构安全可靠;1C1W6-JZQL抢修塔理论计算采用梁杆混合有限元模型,计算结果与试验结果基本一致;试验中塔顶位移超过钢结构设计标准规范值,但构件结构未发生破坏,需进一步研究铝合金杆塔设计标准;塔头斜材及横担端部为1C1W6-JZQL抢修塔薄弱点,应加大构件设计尺寸,防止发生局部破坏;铝-钢材料组合及四肢组合格构式主柱设计提高了抢修塔稳定性,进一步探索了铝合金结构在抢修塔工程领域的应用方式。In order to improve the fast recovery efficiency in the field of power transmission and transformation,expand the application scope of emergency repair tower.Designed a self-standing aluminum alloy emergency repair tower 1C1W6-JZQL in China,and full-scale model test was tested under 7 working conditions,such as strong wind,broken line,installation and operation.The results show that the 1C1 W6-JZQL emergency repair tower has no obvious bending and torsional deformation in the load loading test under 7 working conditions,which indicates that the whole structure of the tower is safe and reliable.1C1 W6-JZQL emergency repair tower used the beam and rod mixed finite element model for the theoretical calculation,and the calculated results are basically consistent with the experimental results.In the test,the displacement of tower top exceeds the steel structure design standard value,but the component structure is not damaged,so the design standard of aluminum alloy tower should be further studied.The tower top diagonal material and web member end pole arm are 1C1W6-JZQL emergency repair tower's weak points,and the design size of components should be increased to prevent local damage.Aluminum-steel material combination and the design of qualified structure main column with four limbs improve the stability of the emergency repair tower,and further explore the application of aluminum alloy structure in the field of emergency repair tower engineering.
