The invention relates to the field of switch equipment, in particular to a circuit breaker chamber interlocking device. An interlocking mechanism of the circuit breaker chamber interlocking device comprises an interlocking rod, wherein a limitation piece sleeves the interlocking rod, a locking position and an unlocking position are arranged on a movable range of the limitation piece, the interlocking mechanism also comprises a cabinet door interlocking piece, the cabinet door interlocking piece is matched with the interlocking rod and leftwards and rightwards moves with the interlocking rod when a cabinet door is closed, so that the cabinet door is maintained locked when a grounding switch is broken, and the locking of the cabinet door can be eliminated when a circuit breaker is arranged at an experiment position. In the circuit breaker chamber interlocking device, interlocking of the cabinet door and the circuit breaker is achieved by the interlocking rod entering in and out of the interlocking piece of the
