Abstract

The utility model relates to an arc starting system of a miniature circuit breaker. The problem that the arc extinguishing efficiency of the conventional miniature circuit breakers is low is solved. The arc starting system of the miniature circuit breaker is characterized in that an arc starting sheet comprises double structures which are parallel to each other and have the same current direction. The arc starting system of the miniature circuit breaker has the advantage of high arc starting efficiency, and effectively improves the short circuit breaking capacity of the circuit breaker.

Description

The miniature circuit breaker arc ignition system
Technical field
The utility model relates to a kind of miniature circuit breaker, specifically is meant the miniature circuit breaker arc ignition system.
Background technology
The circuit breaker arc ignition system is in order to make circuit breaker open circuit or during short circuit; the electric arc that separately produces between the dynamic/static contact can be introduced into arc control device and carry out arc extinguishing; thereby reaching inner each parts of protective circuit breaker is not subjected to effect of arc and is damaged; cause the circuit breaker life-span to be had a strong impact on; the arc ignition system of existing circuit breaker generally all is to adopt the single line structure; that is to say it is the direction of current flow of individual layer; since the magnetic field intensity that this structure produces a little less than; corresponding electromagnetic force is also relatively poor; and make that the magnetic blow-out effect is relatively poor; thereby cause the striking weak effect, cause arc extinguishing efficient low.
Summary of the invention
In order to overcome disadvantages of background technology, the utility model provides a kind of arc ignition system of miniature circuit breaker, and this circuit breaker arc ignition system has the high advantage of efficient, has solved the inefficient shortcoming of existing circuit breaker arc ignition system.
The technical solution of the utility model is: a kind of miniature circuit breaker arc ignition system, comprise binding post, moving contact, fixed contact, conducting strip, striking sheet and arc-chute, described moving contact is electrically connected with binding post by soft connecting conducting wire, bimetallic plates and conducting strip, described striking sheet is electrically connected with conducting strip, described striking sheet, fixed contact and arc-chute constitute arc quenching system, it is characterized in that: the striking sheet contains and is parallel to each other and double-decker that the sense of current is identical.
Further, described striking sheet is formed by connecting by the first striking sheet and the second striking sheet, and the first striking sheet and the second striking sheet around and form the double-decker that is parallel to each other.
Further, described moving contact is connected with the first striking sheet with bimetallic plates by soft connecting conducting wire.
The utlity model has following beneficial effect: owing in this arc ignition system, adopt double-deck striking sheet, and the striking electric current in the same way, thereby make electromagnetic field increase, corresponding electromagnetic force also strengthens, magnetic blow-out is strengthened, when the contact short circuit breaking, the electromagnetic force that strengthens can be introduced arc control device to electric arc apace, quick arc extinguishing, thereby improved arc extinguishing efficient greatly, effectively avoid electric arc to burn the part of circuit breaker inside and caused the reduction in useful life, thereby prolonged useful life, and improved the short circuit breaking capacity of circuit breaker effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, binding post 1, moving contact 2, fixed contact 3, conducting strip 4, the first striking sheets 5, the second striking sheets 6, arc-chute 7, bimetallic plates 8, double-decker 9.
Embodiment
At accompanying drawing embodiment of the present utility model is described further below:
Shown in figure, this miniature circuit breaker arc ignition system, comprise binding post 1, moving contact 2, fixed contact 3, conducting strip 4, striking sheet and arc-chute 7, described moving contact 2 is electrically connected with binding post 1 by soft connecting conducting wire, bimetallic plates 8 and conducting strip 4, described striking sheet is electrically connected with conducting strip 4, described striking sheet, fixed contact 3 constitutes arc quenching systems with arc-chute 7, and the striking sheet contains and is parallel to each other and double-decker 9 that the sense of current is identical.According to such scheme, owing in this arc ignition system, adopt double-deck striking sheet, and the striking electric current in the same way, thereby make electromagnetic field increase, corresponding electromagnetic force also strengthens, and magnetic blow-out is strengthened, when the contact short circuit breaking, the electromagnetic force that strengthens can be introduced arc control device to electric arc apace, quick arc extinguishing, thus improved arc extinguishing efficient greatly.
In the utility model, described striking sheet is formed by connecting by the first striking sheet 5 and the second striking sheet 6, and the first striking sheet 5 and the second striking sheet 6 around and form the double-decker 9 that is parallel to each other.Two striking sheets are connected and form the magnetic blow-out effect is strengthened and improved striking efficient is set, is set to the branch body structure, be convenient to install and with being connected of other parts.
In the utility model, described moving contact 2 is connected with the first striking sheet 5 with bimetallic plates 8 by soft connecting conducting wire, and then be electrically connected with the second striking sheet 6, thereby form double-deck striking sheet and form bidirectional current, striking is effective, and the moving contact 2 of existing arc ignition system is directly to be connected with the striking sheet with bimetallic plates 8 by soft connecting conducting wire, is unidirectional current, form reverse striking electric current, the striking effect is relatively poor.
