The utility model relates to a circuit breaker SF6 status monitoring device specifically is circuit breaker SF6 pressure warning appearance, and it is untimely to solve current circuit breaker SF6 data monitoring, the problem of unable long-range real-time supervision and early warning. The scheme does: include the atmospheric pressure monitoring devices who is connected with circuit breaker SF6's manometer, atmospheric pressure monitoring devices still is connected with CPU, CPU and radio signal dispensing device are connected, circuit breaker SF6 pressure warning appearance still includes the radio signal recepition device, the radio signal recepition device is connected with audible-visual annunciator. Its advantage is: 1, need not the patrolman and frequently tour, practice thrift the manpower, 2, real-time supervision, early warning, it is more high-efficient, 3, dispatch swivel link in the reduction in the middle of need not command center for fault handling speed.
