Π型架空刚性接触网技术研究

On the "Π" Type Rigid Overhead Contact System

介绍了Π型架空刚性接触网的结构和安装技术,以及目前的国产化情况,并与柔性接触网进行了优缺点对比。给出了汇流排的最大支撑间距和最大坡度的一种计算方法。经分析研究以及在部分地铁中的推广使用证明,Π型架空刚性接触网结构简单、安装空间要求小、可靠性高、使用寿命长、安装维修简便,较适合于在地铁供电系统中应用。

With a brief introduction of the structure and installation method of the ＂Ⅱ＂ type rigid overhead contact system （OCS）, and the situation of the present domestic production, this paper compares the strenghth and weakness of the ＂Ⅱ＂ type rigid OCS with the resilient OCS. The anther also proposes a calculation method of the maximum span length and gradients, hoping this ariticle may fumish reference for those who work in the traction power supply OCS of urban rail transit in China.
