Rc系列机车是世界上较早成批生产的交一直晶闸管控制整流器电力机车,也是瑞典近十多年来的干线主型电力机车。该系列最显著的特点是采用他励牵引电动机,以及为保证发挥机车的功率、运行特性和充分利用粘着而装备一套电子控制系统。Rc3型是Rc1型机车的改进型,与Rc2型机车基本相似,所不同的是传动比不等,Rc3机车的速度比Rc2高,牵引力较小,适宜于牵引客车。
Rc series locomotive is the world’s earlier batch production of AC thyristor controlled rectifier electric locomotive, but also Sweden’s main line of the main electric locomotive over the past decade. The most striking features of this series are the use of a traction electric traction motor and the provision of an electronic control system to ensure that the locomotive’s power, operating characteristics and full use of adhesion are achieved. Rc3 is an improved version of the Rc1 locomotive, which is basically similar to the Rc2 locomotive. The difference is that the transmission ratios are different. The Rc3 locomotive has a higher speed than the Rc2 and has a low traction and is suitable for towing a passenger car.
