摘　　要：为了进一步提升高速列车变流器在运行过程中的冷却性能,提高变流器设备舱的通风冷却效率,本文针对某型动车组牵引变流器通风性能进行了实车试验研究,通过在变流器进排风口位置布设传感器,监测高速列车运行过程中变流器设备舱进排风口位置处的进风风量、排风风量.对通风风量的结果和通风风量随列车运行状态的变化规律进行分析,并与变流器散热水温温升规律进行对比分析.分析发现当8车作为头车运行时,行车风方向与风机排风方向一致,促进排风,当1车作为头车运行时,行车风方向与风机排风方向相反,抑制排风.最大抑制风量占列车静置风机全速风量的1.6%.本文研究结果可为高速列车设备舱牵引变流器的设计选型及安装布置方式提供指导.In order to further improve the cooling performance of high-speed train converters during operation, the ventilation cooling efficiency of the converter equipment cabin must be improved. In this paper, the ventilation performance of a traction converter for a type of EMU was studied by real vehicle testing. By placing sensors at the inlet and outlet of the converter, the inlet and outlet air volume and exhaust air volume of the converter equipment cabin in the process of high-speed train operation were monitored. The results of the ventilation volume and the change law of ventilation of trains in a running state were analyzed, and were compared with the law of temperature rise of the converter's cooling water. It was found that when No. 8 car was running as the head car, the driving wind direction was consistent with the fan exhaust direction, promoting the exhaust of air;when No. 1car is running as the head car, the driving wind direction was opposite to the fan exhaust direction,inhibiting the exhaust of air. The maximum suppressed air volume accounted for 1.6% of the full speed air volume of the stationary fan. The results of this study can provide guidance for the design,selection and installation of traction converters in equipment compartments of high-speed trains.
