本文介绍了沈阳至铁岭轻轨的线路概况、供电方式和接触网悬挂方式,陈述了接触网支柱在轻轨供电系统中的作用和重要性。本文列举四种接触网支柱方案并介绍了每个方案的优势和劣势,通过对制造、施工、价格和美观方面的比选并结合线路实际情况,选定圆截面等径钢管柱作为施工方案。通过对钢管柱在一定线路条件下的受力分析,计算出了钢柱底部的控制弯矩,介绍了支柱容量的计算方法。
This article describes the line from Shenyang to Tieling light rail overview, power supply and catenary suspension, catenary strut in the light rail power supply system, the role and importance. In this paper, four types of catenary pillars are listed and the advantages and disadvantages of each scheme are introduced. Through comparison and selection of manufacturing, construction, price and appearance and the actual situation of the line, the steel pipe columns with the same diameter as the circular section are selected as the construction schemes. Through the analysis of the force of the steel pipe column under a certain line condition, the control moment at the bottom of the steel column is calculated, and the calculation method of the pillar capacity is introduced.
