More Information
Summary:The invention provides a switching on and off driving device for a vacuum circuit breaker, belongs to the technical field of high voltage switching devices, and solves the problem that the existing vacuum circuit breaker has a slow switching on and off speed. The switching on and off driving device comprises a bracket, a driving mechanism and an acceleration mechanism. The driving mechanism has adriving rod, and the driving rod can move up and down in the axial direction. The acceleration mechanism comprises a connecting lever, a connecting rod, and an elastic unit, wherein the connecting lever is hinged with the bracket to form a hinge joint 1 and is connected with the driving rod at the other end; the connecting rod is hinged with the connecting lever to form a hinge point 2 and is capable of being stressed and deformed to storage energy in the vertical direction; and the elastic unit enables the connecting rod to have upward thrust, the elastic unit is hinged with the connecting rod to form a hinge point 3
