The utility model relates to an impact type high-voltage movable substation contact device, and particularly to an impact type high-voltage movable substation contact device for a downhole high-voltage movable substation head of a coal mine. The utility model aims to settle a technical problem of providing the high-voltage movable substation contact device which can switch on and switch off a circuit breaker safely and reliability. An adopted technical solution of the impact type high-voltage movable substation contact device is characterized in that: a static contact of the circuit breaker in the high-voltage movable substation is fixedly arranged on a static contact fixing board, and a dynamic contact of the circuit breaker is arranged on a circuit breaker frame which can move horizontally. The impact type high-voltage movable substation contact device is suitable for the coal mine field.
