对运行中直流牵引电动机和异步牵引电动机在内燃机车动力电路中工作时的损耗作了比较分析。指出:当牵引传动装置功率不高时,由于电流高次谐波分量带来的损耗,使异步牵引电动机的经济性不如直流牵引电动机。在单节功率为2200kW的内燃机车上使用异步牵引传动装置会降低其区段速度。
The running loss of DC traction motor and asynchronous traction motor in diesel locomotive power circuit are comparatively analyzed. It is pointed out that when the power of the traction drive is not high, the cost of the asynchronous traction motor is not as economical as that of the DC traction motor due to the loss caused by the higher harmonics of the current. The use of asynchronous traction drives on diesel locomotives with a single power of 2,200 kW reduces the segment speed.
