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.
