Abstract:
An energy storage operation mechanism for a circuit breaker comprises a side plate assembly, a connecting rod assembly, a cam assembly, an energy storage assembly, a rotating shaft assembly and a control assembly. A rotatable driving shaft is mounted in the side plate assembly. The connecting rod assembly and the cam assembly are mounted on the driving shaft. The energy storage assembly and the rotating shaft assembly are mounted at one side of the driving shaft, and the control assembly is mounted at the other side of the driving shaft. The connecting rod assembly is connected with the rotating shaft assembly. The cam assembly can be in contact and connection with the energy storage assembly to push the energy storage assembly to store energy. The control assembly can be connected with the connecting rod assembly and the cam assembly in a latching manner. The energy storage operation mechanism for the circuit breaker, which is provided by the present invention, is compact in structure and high in reliability.

Claim (Index 4):
The energy storage operation mechanism for the circuit breaker according to  claim 2 , wherein in a switching-off energy storage state, a driving shaft is rotated to make the cam assembly to push an energy storage lever of the energy storage assembly in a rotating process, such that the energy storage assembly stores energy, and meanwhile, the switching-on latch of the control assembly pushes the cam assembly to further finish energy storage when the cam assembly rotates in place; the energy storage lever no longer extrudes the connecting rod assembly, and the rotating shaft assembly rotates to make the end part of the switching-off latch of the control assembly slide into a U-shaped groove of the connecting rod assembly, such that the energy storage operation mechanism of the circuit breaker is converted into the switching-off energy storage state; in the switching-off energy storage state, the control assembly drives the switching-on half-shaft by the switching-on guide rod of the interlocking assembly to enable the switching-on latch to be tripped from the cam assembly, the energy storage assembly releases energy and hits against the connecting rod assembly to pull the rotating shaft assembly to finish the switching-on operation; in addition, the end part of the switching-off latch pushes the U-shaped groove to stop the rotating shaft assembly from rotating and resetting, such that the energy storage operation mechanism for the circuit breaker is converted into a switching-on energy release state; in the switching-on energy release state, the control assembly drives the switching-off half-shaft by the switching-off guide rod of the interlocking assembly to enable the end part of the switching-off latch to be separated from the U-shaped groove, and further no longer stop the connecting rod assembly from resetting; the connecting rod assembly drives the rotating shaft assembly to rotate to finish a switching-off operation under a restoring force of main tension springs, such that the energy storage operation mechanism for the circuit breaker is converted into the switching-off energy release state; in the switching-on energy release state, the driving shaft is rotated to make the cam assembly jack the energy storage lever of the energy storage assembly in a rotating process, such that the energy storage assembly stores energy; meanwhile, the switching-on latch of the control assembly pushes the cam assembly when the cam assembly rotates in place, to further finish the energy storage conversion to the switching-on energy storage state.
