The invention discloses a high-voltage electrical device of a contact-net-free railway vehicle. The device comprises a high-speed circuit breaker, at least one protection fuse, a mode selection switch, a lightning arrester, a voltage sensor, a current sensor and a negative wire busbar. The high-speed circuit breaker, the protection fuse, the mode selection switch, the lightning arrester, the voltage sensor, the current sensor and the negative wire busbar are integrated in the same electric appliance box, are electrically connected with one another through cables, wires and copper bars, and are connected with a pantograph, so that the tense roof space can be saved, and the service life of the pantograph is prolonged. Therefore, influence of the fault condition on the normal operation of the system is reduced, and the redundancy reliability of the system is improved.

    本发明公开了一种无触网轨道车辆高压电气装置,包括高速断路器、至少一个保护熔断器、模式选择开关、避雷器、电压传感器、电流传感器和负线汇流排,所述高速断路器、所述保护熔断器、所述模式选择开关、所述避雷器、所述电压传感器、所述电流传感器和所述负线汇流排集成于同一个电器箱内,且彼此之间通过电缆、导线和铜排实现电气连接,并与受电弓连接,能够节省紧张的车顶空间,减小故障情况对系统正常运行的影响,提高了系统的冗余可靠性。
