城市轨道交通供电系统中接触网技术性能和常见故障分析

Technical Performance and Common Fault Analysis of Catenary in Power Supply System of Urban Rail Transit

随着我国城市化进程的不断加快,城市轨道交通工程的数量也在不断增加,对于保障城市的发展具有非常重要的作用,能有效缓解目前日益紧张的城市交通问题,对促进城市的可持续发展也有很大的影响。但城市轨道交通对接触网的依赖性很大,一旦发生故障,将对城市交通网产生重大影响。为此,分别分析了城市轨道刚性接触网和柔性接触网故障的主要原因,并详细阐述了具体的防范措施,希望能为有关单位和人员提供有益的参考。

With the continuous acceleration of China’s urbanization process,the number of urban rail transit projects is also increasing,which plays a very important role in ensuring the development of the city.It can effectively alleviate the increasingly tense urban traffic problems,and also has a great impact on promoting the sustainable development of the city.Once it breaks down,it will have a significant impact on urban transportation network.For this reason,this paper analyzes the main causes of urban rail rigid catenary and flexible catenary failure,and expounds the specific preventive measures,hoping to provide useful reference for the relevant units and personnel.
