重载铁路牵引供电方案与接触网载流能力的分析

Analysis of Traction Power Supply Scheme and the Catenary′s Current-carrying Capacity in Heavy Haul Railways

针对重载铁路以及交流传动机车的特点,对新建重载铁路牵引供电方案与接触网载流能力的关系进行了细致的分析,逐步深入的介绍了重载铁路牵引供电方案设计的几个关键步骤,以及详细的计算方法,并提出了设计中应注意的问题。

According to the characteristics of heavy haul railways and AC drive locomotive, this paper analyzes the relationship between the traction power supply scheme in new- building heavy haul railways and the eatenary＇s currentean＇ying capacity. The several key steps and detailed caleulation method in the traction power supply scheme design are introduced gradually. The problems that should be paid attention in the design are also provided.
