一种槽钢格构式接触网钢柱

目前我国主要的电气化铁路接触网支柱类型,有环形预应力混凝土支柱和横腹杆式预应力混凝土柱、H型钢柱、格构式钢柱、环形钢管柱。经过广泛调研分析,发现槽钢格构式钢柱是一种比较有前途的电气化铁路接触网工程支柱类型。经过计算分析发现其力学性能可以满足普速铁路对于接触网钢柱的性能要求,且相对于传统支柱类型具有更加良好的经济效益,可以作为我国电气化铁路新的接触网支柱类型。

A U-Steel Latticed Pole for Overhead Contact System

At present, the main kind of pole for electric railway overhead contact system are circular prestressed concrete pole, prestressed concrete pole with accrossed-webmember, H shape steel pole, steel latticed column, and steel tube pole. After extensive research and analysis, we found that U-steel latticed pole is a promising pole type for overhead contact system. Through calculation and analysis, it is showed that the mechanical properties of U-steel latticed pole can meet the requirements of general speed railway for overhead contact system. Comparing with the traditional pole type, the U-steel latticed pole has better economic benefits. It can be used as a pole type for overhead contact system of electrified railway in our country.
