摘　　要：牵引变流器作为电力机车的核心部件,振动与温度特性对于牵引变流器的稳定运行至关重要。通过对某型电力机车牵引变流器开展线路运行条件下的振动与温度测试,并从时域和频域角度分析振动特性,从系统级和部件级角度分析温度特性。研究结果表明:牵引变流器柜脚振动主要来自主变压器的高频振动,主要频率为800和1500 Hz;功率模块以轮轨作用的低频振动为主,高频成分少;在GB/T 21563—2018推荐的频率范围,冷却风机的横向振动超出标准值;功率模块水冷散热器相对于进水处的温差约为5.5℃,牵引变流器的温升裕量较大。As the core component of the electric locomotive,the vibration and temperature characteristics are very important to the stable operation of the traction converter.Through the vibration and temperature test of electric locomotive traction converter under the line operation conditions,the vibration characteristics are analyzed from the perspective of time domain and frequency domain,and the temperature characteristics are analyzed from the perspective of system level and component level.The results show that the cabinet foot vibration of the traction converter mainly comes from the high frequency vibration of the main transformer,and the main frequencies are 800 and 1500 Hz.In the power module there is mainly low-frequency vibration caused by wheel rail action,with few high-frequency components.In the frequency range recommended in GB/T 21563—2018,the lateral vibration of the cooling fan exceeds the standard value.The temperature difference between the water-cooled radiator of the power module and the water inlet is about 5.5℃,and the temperature rise margin of the traction converter is large.
