城市轨道交通钢铝复合接触轨供电系统发展综述

Review of the Development of the Power Supply System of the Steel-aluminum Composite Contact Rail in Urban Rail Transit

钢铝复合接触轨是我国城市轨道运输中的重要动力来源,而在早期使用的接触轨大多为低碳钢制。钢铝复合式接触轨在国内外已有较多的使用,具有良好的稳定性、较低的故障率,并且具有很好的发展潜力。该文将从钢铝复合结构轨道设计入手,对我国城市轨道交通供给体系的发展进行了研究,并对其结构、形式进行了详细的分析,以期为今后的发展提供有益的借鉴。

The steel-aluminum composite contact rail is an important power source in urban rail transportation in China,and most of the contact rails used in the early days were made of low-carbon steel.The steel-aluminum composite contact rail has been widely used at home and abroad,with good stability,less failures and good development potentials.Starting from the design of the steel-aluminum composite structure track,this paper studies the development of the China's urban rail transit supply system,and analyzes its structure and form in detail,in order to provide a useful reference for the future development.
