动车组应急供电问题分析及应急自牵引技术方案

Analysis on the Emergency Power Supply of EMUs and Emergency Self-Traction Technical Schemes

动车组在运行过程中,因供电接触网故障造成列车停电。当动车组发生停电故障后,容易因车厢内高温、缺氧等因素造成现场混乱,存在极大的安全隐患。文中分析了既有动车组应急供电中在存在着电池容量不足的问题,介绍了动车组应急自牵引系统的构成及其优势,最后对3种应急自牵引技术方案进行了分析,并通过对比3种技术方案,得到从目前工程实现角度,方案3更加适合;从技术积累角度,方案1和方案2更加适合。

In the course of EMU operation, catenary failure may leading to power off for EMUs. When there is a power failure in E MUs, it is easy to cause panic on the scene due to the high temperature and hypoxia in cars, in which there are great security risks. First of all, the problem of insufficient capacity of emergency battery in present EMUs is analyzed by test data. Then, the system corn position and advantages of emergency self-traction system of EMUs is introduced. In the end, three kinds of emergency self-traction Technical Schemes are analyzed. By comparing the three technical schemes, it is more suitable for scheme 3 from the current project im plementation perspective, and scheme 1 and scheme 2 are more suitable from the perspective of technology accumulation.
