摘要
从直流牵引与交流牵引、牵引电压、接触轨与架空接触网等3个方面对城市地铁和轻轨的牵引供电方式作了比较.认为:交流牵引优于直流牵引;在线路运量较大时,1500V柔性架空接触网受电比750V接触轨受电具有更多的优点.
The traction power supply modes are compared with DC traction and AC traction, traction voltage, contact rail and overhead contact network. The conclusion is that AC traction is superior to DC traction, because the overhead contact network which uses 1500v electric current as its power supply has more advantages than the contact rail which uses 750v electric current in the condition that the volume of traffic is large.
