CRH1A动车组牵引系统参数计算与分析

Calculation and Analysis of the Traction System Parameters of CRH1A EMU

介绍了CRH1A动车组牵引系统的基本结构,根据整车性能的基本指标对牵引系统的参数匹配进行分析和计算;通过对整车进行牵引计算确定牵引电机的轮周牵引功率,进而对牵引变流器、牵引变压器、网侧变流器的参数进行计算。验证了CRH1A型动车组牵引系统满足总体技术指标。

The fundamental structure of CRH1A EMU trac- tion system is introduced. According to the main performances of EMU,parameters of the traction system are analyzed and calculated. Then, through traction calculation of the whole train, the traction power at the wheel rim is confirmed, param- eters of the motor converter, traction transformer and grid-side converter are expounded. Finally,the traction system of CRH1A EMU is proved in terms of the general technical indi- cators.
