FIELD: machine building.
SUBSTANCE: invention relates to a working mechanism with an energy storage device for a circuit breaker, which comprises a side plate assembly, a connecting rod assembly, a cam assembly, an energy storage unit, a rotary shaft assembly and a control unit. Rotary drive shaft is fixed in assembly of side plates. Assembly of connecting rods and cam assembly are fixed on drive shaft. Energy accumulator unit and the rotary shaft assembly are fixed on one side from the drive shaft, and the control unit is fixed on the other side of the drive shaft. Assembly of connecting rods is connected with unit of rotary shaft. Cam assembly can contact and connect with the energy accumulator unit for pushing the energy accumulator unit for energy accumulation. Control unit is configured to be connected to the connecting rod assembly and the cam assembly in a locking manner.
EFFECT: operating mechanism with energy storage device for the circuit breaker envisaged by the present invention has compact design and is characterized by high reliability.
