Background

The operating mechanisms of the circuit breaker mainly comprise three types: the electromagnetic mechanism, the spring mechanism and the permanent magnet mechanism are used for switching on and switching off according to the standard requirements of the breaker operating mechanism so as to finish the breaking and switching on of the power circuit.

In the opening operation process of the spring mechanism breaker, because the opening spring has force, the crank arm has moment rotating clockwise around the output shaft, when the opening trigger coil is excited and then impacts the opening release to rotate anticlockwise, the lock plunger jacks up, and at the moment, the crank arm rotates clockwise, and the connecting rod drives the movable contact of the breaker to move to the opening position. And in the process of closing operation (namely, energy release of a closing spring and the like), after excitation of a closing trigger coil, the closing trigger coil is impacted to rotate anticlockwise, a lock plunger is released, the blocking effect on a pin is released, a moment generated by the closing spring can drive a large gear and a cam to rotate clockwise around a cam shaft, the cam can push a carbon and a crank arm to rotate anticlockwise around an output shaft, and a connecting rod drives a movable contact of a circuit breaker to move to a closing position. And in the energy storage process of the closing spring, an energy storage motor enables the pinion to rotate anticlockwise through the reduction gear and the overrunning clutch, the large gear is forced to rotate clockwise, the closing spring is compressed through the lifting pull rod, the people gear is stopped at the working position after passing through the dead point position through the pin and the lock plunger, and the energy of the closing spring is kept.

The spring mechanism circuit breaker opening and closing action motion is complex, the opening and closing electromagnet is utilized to drive opening and closing, the whole action time is much slower than that of the eddy current repulsive force mechanism circuit breaker (electromagnetic mechanism), the spring mechanism circuit breaker cannot be normally used in specific occasions, the rapidity of the spring operation mechanism circuit breaker is improved, the limitation of the use occasions of the spring operation circuit breaker is changed, the opening and closing speed of the eddy current repulsive force mechanism circuit breaker is high, but the mechanism is complex, and the cost is high.
