    • PROBLEM TO BE SOLVED: To protect an inverter circuit, and to provide the safe travelling of a railroad vehicle.SOLUTION: A vehicle control system includes: the inverter circuit 2; a permanent magnet synchronous motor 6 driven by power from the inverter circuit 2 as a driving force; a crossover 10 connected between the inverter circuit 2 and the permanent magnet synchronous motor 6; an AC current sensor 3 installed between the inverter circuit 2 and the crossover 10; a contactor 5 which is connected between the crossover 10 and the permanent magnet synchronous motor 6, and allows pass or shut off electricity; a DC current sensor 7 connected to the opposite side of the permanent magnet synchronous motor 6 of the inverter circuit 2; and a control unit 9 connected to the contactor 5, the AC current sensor 3 and the DC current sensor 7. The control unit 9 determines an abnormality of a ground fault or a short circuit accident resulting from the crossover 10 in a drive system based on the current value detected from the AC current sensor 3 and the DC current sensor 7, and outputs an opening command to the contactor if the abnormality is detected.
    • 要解决的问题:为了保护逆变器电路,并提供铁路车辆的安全行驶。 解决方案:车辆控制系统包括:逆变器电路2; 由来自逆变器电路2的动力驱动的永磁同步电动机6作为驱动力; 连接在逆变器电路2和永磁同步电动机6之间的交叉10; 安装在逆变器电路2和交叉10之间的交流电流传感器3; 连接在交叉10和永磁同步电动机6之间的接触器5,允许通过或关闭电力; 连接到逆变器电路2的永磁同步电动机6的相对侧的直流电流传感器7; 以及连接到接触器5,AC电流传感器3和DC电流传感器7的控制单元9.控制单元9确定基于驱动系统中的交叉10的接地故障或短路事故的异常 从AC电流传感器3和DC电流传感器7检测的电流值,并且如果检测到异常,则向接触器输出开启指令。 版权所有(C)2012,JPO&INPIT
