地铁列车紧急制动环路研究及优化

Research and optimization of emergencybraking loop for metro train

结合郑州地铁列车紧急制动不缓解的案例,通过对各线路紧急制动环路进行研究,并分析其设计缺陷,从而优化紧急制动接触器选型及环路设计方案,最终形成郑州地铁列车通用的紧急制动环路方案,也可为其他地铁公司设计紧急制动环路提供参考。

With the case study of Zhengzhou metro train emergency brake release failure,through the research of the emergency braking loop on each line,this paper makes an analysis of its design defects,so as to optimize the selection of emergency brake contactor and loop design scheme,and fi nally form a general emergency braking loop scheme suitable for Zhengzhou metro trains,providing reference for other metro operators in the design of emergency braking loop.
