The invention provides a high-voltage isolation interlocking protection circuit and method, a rail vehicle and a train. The circuit comprises a pantograph rising vehicle selection module, a high-voltage isolation switch control module and a high-voltage isolation switch. Wherein the pantograph rising vehicle selection module selects a vehicle needing pantograph rising and generates a selection signal; the high-voltage isolation switch control module generates a high-voltage isolation switch closing instruction under the condition of receiving the selection signal; the high-voltage isolation switch is closed under the condition that the unselected vehicle is in a non-pantograph rising state and receives a high-voltage isolation switch closing instruction, so that the selected vehicle is subjected to pantograph rising; and when the unselected vehicle is in the pantograph rising state, the high-voltage isolation switch closing instruction is not executed, so that the selected vehicle does not rise the pantograph. The circuit is simple in structure, only one of the high-voltage isolating switches of the two vehicles is closed through interlocking logic of the control circuit, the purpose of electrically isolating the two pantographs is achieved, the cost is reduced, and the running safety and reliability of the train are improved.
本发明提供一种高压隔离互锁保护电路、方法、轨道车辆及列车,该电路包括升弓车辆选择模块、高压隔离开关控制模块和高压隔离开关。其中,升弓车辆选择模块选择需要升弓的车辆,并生成选择信号;高压隔离开关控制模块在接收到选择信号的情况下,生成高压隔离开关闭合指令;高压隔离开关在未选中车辆处于未升弓状态且接收到高压隔离开关闭合指令的情况下闭合,以使选中车辆升弓;在未选中车辆处于升弓状态下,不执行高压隔离开关闭合指令,以使选中车辆不升弓。本发明电路结构简单,通过控制电路的互锁逻辑,实现两个车辆的高压隔离开关有且仅有一个闭合,达到两个受电弓电气隔离的目的,不仅降低了成本,也提高了列车的运行安全性和可靠性。
