Problem described in the utility model is realized with following technical proposals：
A kind of omnipotent breaker, composition include housing, static contact, moving contact, tripping mechanism and arc-chutes, improve
Afterwards, insulation arc-extinguishing mechanism is added, the insulation arc-extinguishing mechanism includes insulation shielding plate, armature, yoke, horizontal sliding bar and compression spring,
The yoke is fixed on the side of circuit breaker static contact and less than static contact and the contact surface of moving contact；The insulation shielding plate and
Armature is located at the opposite side of static contact, and insulation shielding plate is fixed on armature and between the moving contact and static contact of breaker
Gap is corresponding；One end of the horizontal sliding bar is fixedly connected with yoke, and screw-in is anti-after the other end sequentially passes through compression spring and armature
De- nut.
Above-mentioned omnipotent breaker, the slide bar and compression spring are respectively provided with two, they are symmetricly set on circuit breaker static contact
Both sides.
Above-mentioned omnipotent breaker, the insulation shielding plate are the dust pan shape put upside down, its front end and the dynamic of breaker touch
Gap between head and static contact is corresponding, and postnotum is through on slide bar and is fixedly connected with armature.
Above-mentioned omnipotent breaker, be additionally provided with Shell of circuit breaker tripping mechanism, stored energy mechanism, intelligent control module and
Magnetic flux buckle releaser.
The utility model is additionally arranged insulation shielding plate can be in breaker disjunction as auxiliary extinction of arc mechanism, auxiliary extinction of arc mechanism
The moment of short circuit current flow acts rapidly, is inserted between moving contact and static contact, and the electric arc for making just to have produced between dynamic and static contact is put out
Go out or reduce, thus shorten the amplification time of arc energy, reduce gathering for arc energy, realize breaker
Short arcing or without arcing.The utility model takes two-stage arc extinguishing, and the electric arc after initial auxiliary extinction of arc can be introduced into arc extinguishing
Follow-up arc extinguishing operation is continued in room, so as to substantially increase the arc extinguishing ability of breaker, it is short also to substantially increase breaker disjunction
The ability of road electric current.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The utility model is to design one special insulation arc extinguishing machine of increase in omnipotent breaker (ACB) stationary contact rostral
Structure, in the moment of circuit failure short circuit current flow, circuit breaker intelligent controller module sends instantaneous trip instruction and action machine
While structure snap action, the insulation shielding plate for the arc-extinguishing mechanism that insulate was rapidly inserted between dynamic and static lift one's head, and moment, which plays, efficiently goes out
The effect of arc.
Referring to Fig. 1~Fig. 7, the utility model includes static contact 1, moving contact 2, the dropout machine being arranged on Shell of circuit breaker
Structure 8, stored energy mechanism 9, insulation arc-extinguishing mechanism, intelligent control module and magnetic flux buckle releaser 10, wherein, insulation arc-extinguishing mechanism includes magnetic
Yoke 3, insulation shielding plate 4, armature 5, compression spring 6 and slide bar 7.
Insulation arc-extinguishing mechanism uses slide bar type structure, and two slide bars 7 are fixed on static contact 1 by yoke 3 and screw, and two
On two slide bars 7, armature 5, insulation shielding plate 4 are integrally fixed and are installed on two slide bars 7 a compression spring 6 by screw
On, the end of two slide bars 7 is equipped with screwed retaining ring, spacing for being carried out to the assembly of armature 5 and insulation shielding plate 4, prevents
The two comes off from slide bar 7, the assembly of armature 5 and insulation shielding plate 4 can overcome under external force the elastic force of compression spring 6 to
Static contact 1,3 one Slideslip of yoke.In circuit failure short circuit current flow, since 1 surrounding of static contact produces very strong electromagnetism
, yoke 3 attracts armature 5 after being magnetized, the assembly of armature 5 and insulation shielding plate 4 overcome the elastic force of compression spring 6 to static contact 1,
3 side quick sliding of yoke, sends instantaneous trip instruction, magnetic flux buckle releaser snap action causes to take off in switch intelligent control module
Buckle mechanism 8 acts, moving contact 2 around axis pin A open rotationally clockwise while, insulation shielding plate 4 is rapidly inserted into moving contact 2
Between static contact 1, play the role of rapid insulation shielding arc extinguishing.After short circuit current flow disappears, the attraction that armature 5 is subject to is therewith
Disappear, assembly homing, whole disjunction of breaker completion under the elastic force effect of compression spring 6 of armature 5 and insulation shielding plate 4
The process of short circuit current flow.Stored energy mechanism 9 is used as combined floodgate energy storage.
Insulation shielding plate 4 forms two-stage arc-control device, auxiliary extinction of arc machine as auxiliary extinction of arc mechanism and original arc-chutes
Structure arc extinguishing when dynamic and static contact is not yet opened completely, and arc-chutes 15 are then to have good put out after dynamic and static contact is opened completely
Go out remaining arcing.
Insulation shielding plate 4 is using high intensity, heat safe engineering plastic materials.It can ensure effectively to divide as defined in product standard
The number (most 3 times) of disconnected short circuit current flow.
Since the arc-control device of MCCB or ACB uses above technical scheme, following technological progress can be obtained：
1 can greatly improve the ability of product disjunction short circuit current flow；
2. it can achieve the purpose that AC and DC is general；
3. in disjunction failed shorted electric current, the further expansion of arc energy can be limited, so that the short of product can be realized
Arcing or without arcing.
