500kV马鞍山大跨越工程跨越塔电梯的设计与应用

Design and Application of Elevator for the 500 kV Line Ma'anshan Crossing Tower

华东电网500 kV滁马线马鞍山大跨越工程跨越塔塔高257 m,是国内目前投运的最高的输电线路钢管塔。塔体中央设置封闭式电梯井筒,内部配置下置式永磁同步无齿轮曳引机变频电梯,电梯提升高度达到了240m。铁塔结构的方案布置、设计和电梯形式的选用、设计等方面为输电线路大跨越结构电梯的选型和设计可提供借鉴。

The 257-meter-high transmission tower built for Ma＇anshan crossing project of East China Grid＇s 500 kV Chu-Ma Line, which is the tallest steel tubular transmission tower in the nation, has closed elevator well in the center of the tower and is equipped with machine-gearless, permanent magnet, synchronous, gearless traction, and frequency conversion elevator with an elevation of 240 m. The tower structural configuration and design, and elevator selection and design provide references for other similar projects.
