摘　　要：牵引变压器温升直接关系到变压器的绝缘寿命和运行的安全性,故需研究高速列车牵引变压器温升随列车实际运行过程中的变化情况。而目前国内变压器温升仿真软件并没有真正有效地用于高速动车组主变压器上。为实时监测列车运行过程中变压器主要部位温升的变化情况,本文采用了发热时间常数法,得到了牵引变压器实时的温度曲线,进一步可得到变压器的温升裕量,为高速牵引变压器热容量的选择及列车的动力配置提供了依据。The temperature rise of traction transformer is directly related to the transformer insulation life and the safety of operation, so ifs necessary to study its temperature changes of traction transformer during the actual operation of the high-speed train. However, at the moment domestic transformer temperature simulation software has not been truly and effectively used for high-speed EMU main transformer. For real-time monitoring temperature changes of the main parts of transformer during train operation, this paper adopts a heating time constant method, and gets a real-time temperature curve Of traction transformer, further obtains temperature rising allowance of transformer, which provides the basis for the heat capacity selection of traction transformer and train＇s power configuration.
