If using the absorbing resistor of the vehicle to absorb the regenerative energy during the train operation,the problem of temperature rise occurs in tunnel and platform,and this consequently increases the weight of the vehicle,results in considerable energy consumption and increases the construction cost and operation cost of the metro.
以往采用车辆吸收电阻吸收地铁列车运行过程中的再生能量,这就带来隧道和站内的温升问题,同时导致车体重量增加,造成大量的能源浪费并使地铁的建设费用和运行费用增加。
