The operation principle of novel vacuum circuit breaker：
Gate-dividing state, static contact 20 and moving contact 35 detach, and moving contact 35 is in bottom；Moving contact keeps seat 32 to be in
Bottom；Moving contact 35 keeps seat 32 to be in topmost with respect to moving contact；Upper cover plate 36 is in topmost；
When combined floodgate, disconnecting switch moving contact 31 moves up, and moving contact holding seat 32, which synchronizes, to move up, in this process
In, moving contact 35 contradicts with static contact 20 and keeps conflict state first；Moving contact keeps seat 32 to continue to move up, upper pressure
Frame 361 gradually plugs in lifting groove 321, and finally upper press box 361 abuts against moving contact supporting block 341, such first compression spring 342
Cushioning effect is played, moving contact 37 and static contact 20 are protected；At the same time, it buckles in the through-hole 362 that 323 plug corresponding side simultaneously
And being finally limited the limitation of fixture block 365, i.e. moving contact 35 keeps 32 remains stationary of seat, such moving contact 35 and quiet with respect to moving contact
Contact 20 keeps conflict state；
So when separating brake, disconnecting switch moving contact 31 moves down under the action of the first tension spring 33, such static contact
20 and moving contact 35 can buckle 323 open-top limiting cards with quick separating, finally due to the effect of a pair of of stop block 371 of downside
Block 365, moving contact keep seat 32 to be detached with upper cover plate 36, and such moving contact 35 and upper cover plate 36 reset.
The above content is only the better embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to this hair
Bright limitation.
