Abstract
The invention provides a protection mechanism and a circuit breaker thereof. The protection mechanism comprises a push rod, and a leakage driving structure and a short circuit driving structure which can drive the push rod to move. The push rod can be mounted inside a circuit breaker in a way which enables the push rod to move back and forth along the axis thereof. The push rod has an initial position at which the push rod does not affect the action of the circuit breaker, and a trigger position at which the push rod triggers the circuit breaker to trip. When leakage occurs, the leakage driving structure drives the push rod to move from the initial position to the trigger position to trip the circuit breaker and break the circuit. When a short circuit occurs, the short circuit driving structure drives the push rod to move from the initial position to the trigger position to trip the circuit breaker and break the circuit. According to the protection mechanism, no matter whether leakage or a short circuit occurs, the circuit breaker can be triggered to trip, and thus, higher safety is achieved. On the basis of the prior art, the function of short circuit protection is achieved by only adding the short circuit driving structure which drives the push rod to move under the condition of a short circuit. The protection mechanism has the advantages of compact structure and low cost.
