城市轨道交通接触轨电分段设置方式与改进建议

介绍和阐述城市轨道交通接触轨电分段的3种设置方式,对其应用条件和存在问题进行分析,重点分析列车的失电与连电现象。在此基础上,结合磁浮交通动力轨电分段中嵌入式分段绝缘器技术,提出接触轨电分段设置方式的改进建议,认为在城市轨道交通接触轨电分段中应用嵌入式分段绝缘是可行的。

Methods and Improvement Suggestions on Electrical Sectioning of Contact Rail of Urban Rail Transit

The paper introduced and expounded three methods of electrical sectioning of the contact rail of urban rail transit,analyzed their application conditions and the existing problems,and especially analyzed the phenomena of train power loss and power connection. On that basis,by reference to the embedded section insulator technology used in power rail of magnetic suspension transit,some suggestions on how to improve the method of electrical sectioning of contact rail were proposed in this paper. One conclusion is that it is feasible to use the embedded section insulator technology for electrical sectioning of contact rail in urban rail transit.
