Abstract
The utility model relates to a plug-in type energy-storage high-breaking mini breaker which comprises a casing and an operating mechanism, an electromagnetic system, a bimetallic strip, an explosion chamber and a binding post which are mounted in the casing. A kidney-shaped through hole is transversely arranged in the operating mechanism, and the operating mechanism is hinged to the casing via the kidney-shaped through hole. A contact shaft can move in the kidney-shaped through hole when the breaker is switched on/off. When a switch is closed, a moving-contact seat moves towards a static contact due to combined efforts of a U-shaped rod and an extension spring, thereby providing gap compensation for a moving contact; and it is only required to fix the moving contact on the moving-contact seat instead of arranging an extension spring between the moving contact and the moving-contact seat, so that the structure of the operating mechanism is simpler.

Stored energy mechanism plays the object of quick-make: start turning handle, U-shaped bar promotes tripping, make snap close and tripping meshing, thereby promoting tripping, snap close, movable contact block and movable contact head sways, when handle motion is to certain angle, on movable contact block, salient point withstands on countercheck rod, movable contact block and moving contact stop travelling forward, continue motion handle motion to certain angle, handle promotes energy storage lever, energy storage lever pulls countercheck rod to move upward, and countercheck rod separates with movable contact block, moving contact quick-make under the effect of extension spring power.
The utility model is further set to be provided with multiple steam vents on the housing at described arc control device rear.
Above-mentioned steam vent body is specifically set to three, is separately positioned on binding post place, binding post below and the housing bottom of housing.
On housing between the steam vent of above-mentioned housing bottom and arc control device rear, form an exhaust passage.
Traditional product only arranges place's exhaust outlet, and the utility model when disjunction, is more conducive to the discharge of gas compared with traditional product, has improved the breaking capacity of product.
The housing both sides that the utility model is further set to described arc control device front end are provided with flash barrier, flash barrier inner side forms inclined-plane, between flash barrier, form by inclined-plane the arc passage narrowing gradually, the top of two flash barriers forms the push rod mutually supporting relatively, is provided with the run-on tab being connected with bimetal leaf between the below of two flash barriers.Flash barrier top is supported mutually by push rod, and the run-on tab of below between passing through supports, and makes the setting of flash barrier more stable, can mutually not draw close.
The utility model is further set to described movable contact block lower end and forms the moving contact groove suitable with moving contact, and moving contact is fixedly installed in moving contact groove.Moving contact is placed in the moving contact groove of movable contact block, has saved the operations such as the fixing and screw of gluing is fixing compared with tradition, provides cost savings.
