With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, belongs to the scope of protection of the utility model.
The utility model embodiment is described in further detail below in conjunction with attached drawing.
Embodiment one
As shown in Fig. 1 to Fig. 3, a kind of dc circuit breaker operating mechanism, including vacuum tube 1, conductive push rod 2, pivoted arm 3, electricity
Magnetic mechanism 4, shift fork 5, ratchet 6, pedestal 7, buckle releaser 8, moving contact 9 and static contact 10.
Vacuum tube 1, electromagnetic mechanism 4 and the buckle releaser 8 is both secured on pedestal 7；Wherein, the vacuum tube 1 is logical
Two pieces of insulation support plates 12 are crossed to be fixed on pedestal 7.The electromagnetic mechanism 4 can be directly fixed on buckle releaser 8 by screw
On pedestal 7.
Installation moving contact 9 and static contact 10 in the vacuum tube 1；Specific installation is as shown in Figure 1,9 external part of moving contact
It is connect with conductive push rod 2；Specific 9 external part of moving contact is connected through a screw thread with conductive push rod 2.And conductive push rod 2
Resetting spring 11 is set between vacuum tube 1；3 lower end of pivoted arm is articulated on pedestal 7, and upper end and conductive push rod 2 are slide hinged；
It is slide hinged to refer to being equipped with long skidway hole in 3 lower end of pivoted arm, while the axis pin of conductive push rod 2 slides in long skidway hole also
It can rotate.Ratchet 6 is set to 3 middle part of pivoted arm；The effect of ratchet 6 is unidirectional rotatable, and other direction is equivalent to a hook, this
Reference chart 1 in example, can rotate clockwise, cannot rotate counterclockwise.Can certainly directly it be replaced with a hook
It uses.

Card slot in；The end of the buckle releaser 8 is set to the top for 5 front end of shift fork stretched out, and refers here to buckle releaser 8 and exists
Position under normal conditions.
Operation principle
As shown in Figure 1, when dc circuit breaker is connected to close commands, electromagnetic mechanism 4 obtains the electric electromagnetic force that passes through and pushes driving
Shift fork 5 moves right, and ratchet 6 is stuck in the card slot of 5 front end of shift fork, drives pivoted arm 3 to rotate clockwise, driving force is transmitted
To conductive push rod 2, conductive push rod 2 transfers a driving force to moving contact 9, and moving contact 9 moves right, and contacts and closes with static contact 10
It closes, at the same time the resetting spring 11 at conductive push rod 2 stretches into 8 end of buckle releaser by compressed energy-storage, the end of 5 front end of shift fork
The lower part of head, as shown in figure 3, breaker closing is completed.
When breaker disconnects, make 4 dead electricity of part electromagnetic mechanism lose electromagnetic driving force, conductive push rod 2 and moving contact 9 by
The power of resetting spring 11 resets, 3 spinning reduction counterclockwise of pivoted arm, as shown in Fig. 2, breaker disconnects.
The unexpected overcurrent of main circuit when breaker is in closed state, 8 trigger action of buckle releaser, end push shift fork 5
The end of front end makes ratchet 6 be detached from the card slot of 5 front end of shift fork to lower swing or flexible deformation, and moving contact 9 is resetted
The power of spring 11 resets, and breaker disconnects.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
