摘　　要：交流传动电力机车可以担当2 000~3 000km及以上长交路的列车牵引任务,但是有3个制约因素,一是不良气象条件下轨面潮湿时沙子可能不够用,二是空气严重污染潮湿气温较低且低速运行时车顶绝缘子可能闪络,三是机车跨局整备问题。还提出了在有霜期机车后置运行减少用沙量并可节约能源。This paper considers that AC drive electric locomotive can undertake the train traction task of 2000~3000km or more long routing,but there are three restricting factors：（1）the sand may be not enough due to humidity of rail surface;（2）the roof insulator may flashover under the condition of serious air pollution,humid air,low air temperature and low speed;（3）the locomotive servicing cross different bureaus is a problem.It also puts forward the rear locomotive running which can reduce sand usage and energy consumption during the frost season.
