地铁1500V制动能量消耗装置应用

随着我国城市轨道交通建设的快速发展,国内轨道交通主要采用电气再生制动方式。电气再生制动是城市轨道列车运行中的一个关键、重要的技术,关系到列车能否安全、准确、稳定地进站、停车。目前,在国内各大城市的地铁列车均采用电气再生制动方式(简称制动技术),在牵引变电所内设置有一套制动能量消耗装置,文章重点介绍了制动能耗装置的工作原理和保护设置,针对在实际运用中出现的一些问题进行分析、总结,并提出合理化建议。

With the rapid development of urban rail transit construction in China, the electric regenerative braking mode is mainly used in the domestic rail transit. Electrical regenerative braking is a key and important technology in the operation of urban rail train, which relates to whether the train can enter and stop safely, accurately and stably. At present, the subway trains in major cities in China adopt the electric regenerative braking mode （abbreviated as braking technology）, and a set of braking energy con-sumption devices are installed in the traction substations. This paper mainly introduces the working principle and protection setting of brake energy consumption device, analyzes and summarizes some problems in practical application, and puts forward some reasonable suggestions.
