Abstract
The utility model discloses a miniature circuit breaker, including an arc-separating plate (1), an arc-extinguishing chamber (2), an electromagnetic system (4), a movable contact, a static contact (7) and a magnet yoke (5), wherein the magnet yoke (5) or the arc-extinguishing chamber is connected with an arc-striking angle (6), and the tag end of the arc-striking angle (6) is arranged between an closed angle position (8) of the movable contact and the arc-extinguishing chamber (2). The beneficial effects of the utility model is that the circuit breaker has a strong striking arc and improves a breaking capacity.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of miniature circuit breaker.
Background technology
As shown in Figure 1, the moving contact wedge angle position 8 and the distance between the arc control device 2 of existing miniature circuit breaker are bigger, when moving contact separates with fixed contact 7, can produce electric arc, the existing main arc control device 2 beneath arc leading angles (also citing approvingly the arc sheet) that lean on come arc extinguishing, and the effect of arc extinguishing is bad, thoroughly arc extinguishing, very easily burn out moving contact, thereby the generation loose contact, the effect of arc extinguishing is bad, and circuit breaker is in the process of disjunction, the electric arc that produces is difficult for eliminating, and breaking capacity is poor.
Summary of the invention
At the shortcoming of existing circuit breaker, the utility model provides a kind of novel circuit breaker.
To achieve these goals, technical solution adopted in the utility model: a kind of miniature circuit breaker, comprise flash barrier 1, arc control device 2, electromagnetic system 4, moving contact, fixed contact 7 and yoke 5, be connected with arc leading angle 6 on described yoke 5 or the arc control device 2, the end of arc leading angle 6 is between moving contact wedge angle position 8 and arc control device 2;
Described arc leading angle 6 is an arc.
The beneficial effects of the utility model: strong striking arc, improve breaking capacity.
Description of drawings
Fig. 1. the structural representation of existing circuit breaker.
Fig. 2. the structural representation of the utility model embodiment 1.
Fig. 3. the structural representation of the utility model embodiment 2.
Embodiment
See also its implementation process of description of drawings:
A kind of miniature circuit breaker comprises flash barrier 1, arc control device 2, and electromagnetic system 4, moving contact, fixed contact 7 and yoke 5 are connected with arc leading angle 6 on described yoke 5 or the arc control device 2, and the end of arc leading angle 6 is between moving contact wedge angle position 8 and arc control device 2; Described arc leading angle 6 is an arc.Circuit breaker is pressed operating mechanism when operate as normal; make power connection; tripping mechanism locking this moment; the contact akinesia, when electric current was excessive, the bimetal leaf of electromagnetic system produced crooked; promoted snap close; tripping is discharged, and contact is finished the disjunction protective effect of circuit breaker under the effect of retracting spring and disconnect.The effect of yoke 6 of the present utility model is introduced arc control device 2 with electric arc exactly, and striking arc improves breaking capacity greatly so by force.
Claims (2)
1, a kind of miniature circuit breaker, comprise flash barrier (1), arc control device (2), electromagnetic system (4), moving contact, fixed contact (7) and yoke (5) is characterized in that, be connected with arc leading angle (6) on described yoke (5) or the arc control device (2), the end of arc leading angle (6) is positioned between moving contact wedge angle position (8) and the arc control device (2).
2, a kind of miniature circuit breaker according to claim 1 is characterized in that, described arc leading angle (6) is an arc.
