Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, becomes apparent from those skilled in the art
Ground understands how to put into practice the utility model.Although describing the utility model with reference to its preferred embodiment, these
Embodiment simply illustrates, rather than limitation the scope of the utility model.
As shown in Figures 1 to 3, the utility model utilizes the breaker structure of electrodynamic repulsion force rapid-releasing, including housing 1, institute
State and operating mechanism, magnetictrip 2, moving contact 3, static contact 4 are provided with housing 1, the operating mechanism is by transmission mechanism and certainly
It is made up of tripping mechanism two parts, the transmission mechanism is handle transmission mechanism, and the handle transmission mechanism includes handle 5, connected
Bar 6, tripping spring 7, the free tripping mechanism include tripping 8 and the lock 9 of hasp connection, one end of the tripping spring 7
It is fixed in the spring base 10 in tripping 8, the other end of tripping spring 7 is fixed on the inner side of housing 1, and the moving contact 3 is rotationally
It is articulated with tripping 8, one end of the lock 9 is provided with the shake-up boss 11 being engaged with magnetictrip 2, described to latch on 9
Provided with limited post 12, the limited post 12 is vertically installed in the side of lock 9, and one end of the connecting rod 6 is articulated with handle 5,
The other end of connecting rod 6 is articulated with tripping 8, and the handle 5 is linked by connecting rod 6 and tripping 8, then drive moving contact 3 with it is quiet
Contact 4 coordinates, wherein, the handle 5 is arranged at the outside of housing 1, and the magnetictrip 2 is arranged at convex with shake-up in housing 1
The corresponding position of platform 11.
Pull bar 13 is hinged with the lock 9.One end of pull bar 13 is be hinged with lock 9, and the other end is located at double in housing 1
Sheet metal side.
The bending of connecting rod 6 is in obtuse angle.
The top of the moving contact 3 is provided with strip slot 14, and corresponding to the position of strip slot 14 on housing 1 is provided with slotted eye, Ke Yili
Slotted eye and strip slot 14 are passed through with pivot pin, two or three breakers is threaded off when using side by side and links, or and earth leakage protective device
Support the use.
The operation principle of the breaker structure：Short circuit current arrived and electrical apparatus release action before, arc voltage due to
Contact closure remains zero.At this moment, handle 5 is stuck in the outside of housing 1, and tripping spring 7 is in compressive state, and free tripping mechanism will be dynamic
Contact 3 is locked in closing position, and moving contact 3 and static contact 4 close and have precompression between contact.When high current arrives, can produce
Raw certain electrodynamic repulsion force, if electrodynamic repulsion force is greatly to overcoming contact precompression, then operating mechanism also no two contacts before action
It will be opened by reprimand, magnetictrip 2, which promotes, touches the release moving contact 3 of the unblock of boss 11 lock 9, and moving contact 3, static contact 4 are electronic
Being separated in the presence of repulsion, moving contact 3 further separates in the presence of tripping spring 7 with static contact 4, then lights electric arc,
So play short-circuit protection effect.
Wherein, contact is caused to denounce electrodynamic repulsion force and loop electrodynamic repulsion force sum of the electrodynamic repulsion force opened between contact.It is spacing
The position that post 12 is used to after opening moving contact 3 rotate is spacing.Contact opening direction, with reference in figure 1 for counterclockwise, or figure
Direction shown in 3.
Another embodiment, limited post 12 are used as a magnet, coordinated with magnetictrip 2.When high current arrives, limited post 12
Certain electrodynamic repulsion force can be produced with magnetictrip 2, if electrodynamic repulsion force is big to overcoming contact precompression, then operating mechanism
Before not acting also, two contacts first pass through limited post 12 and pull the release moving contact 3 of lock 9, move and touch 3 effects in tripping spring 7
Under further separated with static contact 4, breaker is quickly disconnected.
It should be pointed out that for the utility model through absolutely proving, can also have a variety of conversion and the implementation of remodeling
Scheme, it is not limited to the specific embodiment of above-mentioned embodiment.Above-described embodiment as just explanation of the present utility model, and
