摘要
分析了某型电力机车辅助变流系统主电路的拓扑结构,着重对其接地检测电路、接地判断方法进行了介绍,并通过Matlab/Simulink仿真对系统不同点发生接地故障时接地检测电压不同特点进行了分析,验证了接地检测方法的可行性。
The main circuit topological structure of the auxiliary converter system in a certain electric locomotive is analyzed focusing on grounding detection circuit and grounding judgment method,and the detection voltage characteristics of different grounding fault points are analyzed by Matlab/Simulink simulation,which verifies the feasibility of the grounding detection method.
