摘要
高速动车组牵引传动单元的工作状态关系到列车的运行安全,对其温升情况的监视尤为重要。通过对动车组牵引电机轴承以及齿轮箱温度监控技术进行分析,并结合运用情况提出了优化方案。
The working conditions of traction drive unit are related to the running safety of high speed EMUs,and the temperature monitoring for this unit is particularly important.This paper analyzes the temperature monitoring technology of traction motor bearing and gear box,and proposes the optimization scheme combined with the EMU operation conditions.
