The embodiment of the invention discloses a rail transit vehicle traction bus interlocking breaking circuit and a control method thereof. The device comprises a third rail power supply, a first current collector, a second current collector, a warehouse power supply, an isolating switch, a bus breaker box, a traction inverter, an auxiliary inverter and a traction controller. The first end of the isolating switch is connected with the auxiliary inverter, the second end is connected with the traction high-voltage bus and one end of the first current collector, and the third end is connected with a garage power supply; one end of the second current collector is connected with a traction high-voltage bus and a traction inverter through a bus circuit breaker box, the other end of the first current collector and the other end of the second current collector are connected with a third rail power supply, and the traction controller is connected with the bus circuit breaker box; and the bus circuit breaker box is controlled to connect or disconnect the third rail power supply and the traction high-voltage bus. Through the above mode, the embodiment of the invention can perform automatic opening and closing control on the breaking of the bus in a remote automatic control mode, and is flexible in use scene and high in availability.
