传统的列车电阻制动是将制动电阻装设在车辆底部,该方式下车体重量增加,且制动产生的大量热量散发在地铁隧道和车站内,增加了对通风系统的要求,从而导致地铁建设投资和能耗的增加。随着社会环保节能意识的增强和科技进步,在牵引变电所设置再生制动能量吸收利用装置,对于减少城市轨道交通用电量及对环境的影响,促进节能减排,起着重要作用,成为当前的研究热点。
The traditional train resistance braking is to install the braking resistor on the bottom of the vehicle. In this way, the weight of the vehicle body increases, and a large amount of heat generated by the braking dissipates in the subway tunnel and the station, increasing the requirements for the ventilation system, resulting in Subway construction investment and energy consumption increase. With the enhancement of social awareness of environmental protection and energy saving and technological progress, setting regenerative braking energy absorption and utilization devices in traction substations plays an important role in reducing the urban rail transit electricity consumption and its impact on the environment and promoting energy conservation and emission reduction. Become the current research hotspot.
