Description
Technical field
the utility model relates to a kind of breaker arc extinguishing chamber device.
Background technology
arc control device device is the parts of an outbalance in the arc extinguishing system of circuit breaker, and it all is to refill in the arc control device arrangement cavity that is fitted on circuit breaker after adopting arc extinguishing grid pieces 1 to assemble riveted together with flash barrier 2 usually.In conjunction with Fig. 1,2,3, shown in 4; Can know present breaker arc extinguishing chamber device, positioning hole corresponding 2a rivets together and fixes on some convexities that its arc extinguishing grid pieces 1 (Fig. 2, Fig. 3) and flash barrier 2 (Fig. 4) are provided with through arc extinguishing grid pieces 1 both sides and the flash barrier 2.
In
existing above-mentioned arc control device device; Neighbouring arc extinguishing grid pieces 1 bottom notch shape size all consistent (all being to be symmetrical " ampuliform " breach); During assembling, marshalling is overlapping between the arc extinguishing grid pieces 1, and the noninterlace ginseng is inferior; Can not effectively cut the circuit breaker branch electric arc that produces of having no progeny like this, thereby cause the breaker arc extinguishing performance to reduce.In addition, be positioned at top in the existing arc control device device and bear the arc extinguishing grid pieces 1 of striking effect and lack effective striking position, the electric arc that makes the circuit breaker branch have no progeny to produce can not be rapidly effective entering arc control device; Simultaneously, flash barrier 2 areas in both sides are bigger, and the circuit breaker branch electric arc that produces of having no progeny can strengthen its carbonization area like this, reduces the striking performance, so present organization plan is difficult to the effectively break performance of lifting circuit breaker.
Summary of the invention
the utility model purpose is: provide a kind of simple in structure, and the better breaker arc extinguishing chamber device of arc extinction performance effectively improves the break performance of circuit breaker with this.
The technical scheme of
the utility model is: a kind of breaker arc extinguishing chamber device; Comprise being fixed on and be some arc extinguishing grid pieces of arranging in the gap between two flash barriers; The bottom of each arc extinguishing grid pieces is provided with breach; The arc extinguishing grid pieces that wherein is positioned at topmost is the top arc extinguishing grid pieces, and be positioned at arc extinguishing grid pieces below, top be the bottom arc extinguishing grid pieces; It is characterized in that the bottom notch shape left-right symmetric of said adjacent bottom arc extinguishing grid pieces, and be staggeredly stacked to arrange and be the fish scale shape.
as a rule; Do not limit for the shape of bottom arc extinguishing grid pieces bottom notch is concrete in the utility model, only need the notch geometry symmetry of two neighbouring bottom arc extinguishing grid pieces and can be staggeredly stacked to arrange to produce cataphracted form and get final product.But in the manufacturing process of reality, the utility model also has preferred form following:
The bottom of each bottom arc extinguishing grid pieces is provided with two sections breach described in
the utility model; Said first section breach is the rectangle breach; Said second section breach is eccentric " eight " font breach, and the both sides of said off-centre " eight " font breach link to each other with the top, both sides of rectangle breach.
perhaps; The bottom of each bottom arc extinguishing grid pieces described in the utility model is provided with two sections breach; Said first section breach is trapeze cut; Said second section breach is eccentric " eight " font breach, and the both sides of said off-centre " eight " font breach link to each other with the top, both sides of trapeze cut.Because the notch geometry of two neighbouring bottom arc extinguishing grid pieces needs left-right symmetric, so the eccentric direction of eccentric " eight " font breach in the bottom of two neighbouring bottom arc extinguishing grid pieces alternately distributes.
For the electric arc that makes the circuit breaker branch have no progeny to produce can be introduced in the arc control device more fast, the utility model is further made following improvement:
The top arc extinguishing grid pieces is provided with the striking sheet that raises up described in
the utility model.
are further preferred, and angle is a between sheet of striking described in the utility model and the top arc extinguishing grid pieces, 30 °≤a≤90 °.
are further preferred, and the sheet of striking described in the utility model one is connected in the breach inner edge top on the arc extinguishing grid pieces of top.
The introducing of
said striking sheet can make that the magnetic line of force on the arc extinguishing grid pieces breach inner edge of top is more concentrated, strengthens suction, thereby makes electric arc to be introduced in the arc control device more rapidly.Certainly because generally speaking, electric arc all is to contact the top arc extinguishing grid pieces at first, gets final product so also only on the arc extinguishing grid pieces of top, increase arc quenching plate in the utility model.The same routine techniques of notch geometry in the utility model on the arc extinguishing grid pieces of top does not improve.
are preferred, and flash barrier described in the utility model is H shape.The flash barrier of both sides is designed to H shape, its objective is to reduce the carbonization area, raising striking performance is further accelerated extinguishing of electric arc with this.
are the same with routine techniques, and the both sides of said each arc extinguishing grid pieces of the utility model (comprising top arc extinguishing grid pieces and bottom arc extinguishing grid pieces) are equipped with some convexities, supply protruding supporting into the fixing location hole of riveted and have on the flash barrier.
This breaker arc extinguishing chamber device that
the utility model provides is the same with routine techniques when assembling, and its arc control device placing chamber of putting into breaker body by correct direction is got final product.
The utility model has the advantages that:
are this Arc Distinguishing Device for Circuit Breakers that provides of the utility model 1., compares prior art, and its striking is rapid, and arc extinction performance is better, can effectively improve the break performance of circuit breaker.
are this Arc Distinguishing Device for Circuit Breakers that provides of the utility model 2.; Its technical scheme is simple; The original appearance structure of breaker body can not changed; And do not influence on the basis of its operating characteristic, change through simple planform, solve the problem that electric arc can not effectively get into arc control device fast.
are this Arc Distinguishing Device for Circuit Breakers that provides of the utility model 3.; The same with routine techniques, need not increase other corollary apparatus, so when improving break performance greatly; Do not increase cost, thereby help improving the competitiveness of product in market.
