为了研究牵引电动机在过分相时的暂态特性,以CRH2型动车组YQ-365型牵引电动机为研究对象,针对地面开关自动过分相开关的合闸与分闸所产生的过电压,利用Matlab/Similink搭建了地面开关式自动过分相牵引电动机暂态特性仿真实验平台,研究了过分相工况下牵引电动机电气特性变化情况。

In order to study the transient characteristics of traction motor in Passing Neutral Section, regarding YQ-365 traction motor of CRH2 EMU trains as the research subject, based on over-voltage of switch closing and opening of ground＇s auto-passing neutral section at switching time, experimental model of transient characteristics of traction motor of ground＇s auto-passing neutral section at switching time in simulation platform is set up based on Matlab/Simulink, and the change of electrical characteristics of traction motor ...
