特高压变电站格构式构架安装工艺要点浅析

UHV Substation Lattice Truss Installation Process Key Points

特高压变电站构架多为格构式构架,构架构造复杂、跨度大、吊装高度高、安装工作量大,构架分节安装,对技术措施要求高,精度控制要求严。文章从特高压1000k V皖南变电站格构式构架安装工艺要点出发,介绍其控制要点及控制措施,以做总结及交流。

UHV substation truss is usually lattice structure , the structure of the truss is complex , with large span and high hoisting height , having the large workload of installation , and sectioned to install , with the high requirement for technical measures and the strict accuracy control .In this paper , from the key points of the lattice truss installation process of 1000 kV UHV substation of Wannan , the control points and control measures are introduced , to summarize and exchange .
