摘　　要：长大坡道、海拔变化大等特殊运用环境对电力机车通风冷却系统影响较大,进而影响牵引电机温升,为确保电力机车能够同时在平原和高原特殊运用环境下正常运行,在电力机车牵引电机温升设计时,应充分考虑特殊运用环境对牵引电机温升的影响。本文阐述了高原环境适应性改进HXD1型电力机车牵引电机温升设计,综合考虑机车的运行特点,从牵引温升限值、执行标准、温升计算以及冷却风量计算等方面进行了论述。The special operating environment,such as as long and Big Ramp,high altitude change,has great influence on the ventilation and cooling system of the locomotive,and then affects the temperature rise of traction motor.In order to ensure the normal operation of the locomotive in plain and plateau environment,the influence of special environment on the temperature rise of traction motor should be fully considered in the design of traction motor temperature rise.This paper describes the design of temperature rise of traction motor for HXD1 locomotive with plateau environment adaptability,the paper discusses the limit value of traction temperature rise,the execution standard,the calculation of temperature rise and the calculation of cooling air volume.
