Abstract
The utility model relates to a novel structure of a circuit breaker arc-extinguishing chamber, which comprises arc partition walls and arc chutes, wherein an arc-extinguishing cover made from an insulating material is additionally arranged at the tops of the two arc partition walls, and the two ends of the arc-extinguishing cover extend downwards to form a three-dimensional door-shaped structure; and the two side walls of the arc-extinguishing cover with the door-shaped structure are used for covering the long and narrow parts of the arc chutes at both sides. The structure not only effectively increases the covering area of the arc chutes, but also increases the pressure in the arc-extinguishing chamber, and leads electric arc to quickly move to an electric arc eliminating zone, thereby effectively improving the arc extinguishing effect.
Description
Technical field:
The utility model relates to a kind of improvement of breaker arc extinguishing cell structure, particularly to the improvement of existing mold cased circuit breaker, belongs to low-voltage electrical apparatus manufacturing technology field.
Background technology:
The structure of existing mold cased circuit breaker arc control device as shown in Figure 1, it mainly is made of the arc-chute 3 that the arc separating wall 1 that adopts insulating material to make, arc cover plate 2 and employing metal material are made, and its effect is the electric arc that cooling, elimination are produced by circuit breaker disjunction short circuit current.Though the arc cover plate 2 of the mold cased circuit breaker arc control device of this structure has certain arc effect, it can not be protected the zone that is subjected to electric arc influence; Therefore in addition, this arc cover plate is a planar structure, and intensity is relatively poor, is not enough to bear the stress that is produced by electric arc and can produces and break, thereby influence arc quenching effect.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of rational in infrastructure, breaker arc extinguishing chamber of new structure that arc quenching effect is good.
For achieving the above object, the utility model has been taked following technical measures:
A kind of breaker arc extinguishing chamber of new structure described in the utility model, include arc separating wall, arc-chute two parts, top at two arc separating walls, added an arc extinguishing lid that adopts insulating material to make, the two ends of this arc extinguishing lid are extended formation one downwards and are three-dimensional door word structure, and the two side that is the arc extinguishing lid of a word structure is used to cover the long and narrow part of both sides arc-chute; This structure has not only increased the area coverage of arc-chute effectively, and has increased the pressure in the arc control device, and pilot arc is shifted to electric arc fast and eliminated the district, thereby has improved arc quenching effect effectively.

Fig. 1 is the structural representation of existing circuit breaker arc control device
Fig. 2 is a structural representation of the present utility model
Wherein: 1-arc separating wall 2-arc cover plate 3-arc-chute 4-arc extinguishing lid 5-arc extinguishing lid sidewall
Embodiment:
A kind of breaker arc extinguishing chamber of new structure described in the utility model, include arc separating wall 1, arc-chute 3 two parts, top at two arc separating walls 1, added an arc extinguishing lid 4 that adopts insulating material to make, the two ends of this arc extinguishing lid 4 are extended formation one downwards and are three-dimensional door word structure, and the arc extinguishing lid sidewall 5 that is a word structure is used to cover the long and narrow part of both sides arc-chute 3; The material of arc extinguishing lid 4 can adopt nylon 66 or poly-carbon ester material to make, and has enough intensity to guarantee it.Not only increased the area coverage of arc-chute effectively through the utility model after the above-mentioned design, and increased the pressure in the arc control device, pilot arc is shifted to electric arc fast and is eliminated the district, thereby has improved arc quenching effect effectively.
