Abstract
The utility model discloses a breaker arc extinguishing structure with an arc barrier, which comprises an arc extinguishing chamber, wherein an air vent channel is arranged behind the arc extinguishing chamber; and the breaker arc extinguishing structure is characterized in that the arc barrier is arranged at the position of the air vent channel behind the arc extinguishing chamber. The arc barrier is an S-shaped metal part and provided with mesh holes. When a movable contact and a fixed contact disconnect current, flashover is led into the arc extinguishing chamber. By cutting of the arc barrier plates of the arc extinguishing chamber, residual electric arc further passes through the arc barrier and is cut into sections by the arc barrier plates, thus increasing the contact area of the electric arc and air, fast absorbing and cooling the electric arc so as to carry out secondary arc extinguishing, and greatly reducing the escape of arc light; and simultaneously the mesh holes of the arc barrier can intercept the slopping generated by arc extinguishing inside a breaker.
Description
Technical field
The utility model relates to a kind of breaker arc extinguishing structure.
Background technology
Existing miniature circuit breaker is generally realized by moving contact, fixed contact, striking sheet, flash barrier, arc control device, is provided with steam vent at housing parts simultaneously.When the moving contact of circuit breaker and fixed contact breaking current, the electric arc that produces between contact is guided arc control device into by moving contact, fixed contact, flash barrier, striking sheet, and arcing is behind the arc control device arc extinguishing, and the part arcing is by the steam vent ejection of Shell of circuit breaker.Above-mentioned breaker arc extinguishing mode exists arc extinguishing not thorough, and arc light escapes, steam vent has the defective of spraying the slag discharge, not only influences the life-span of circuit breaker, has potential safety hazard simultaneously.
The utility model content
The utility model purpose is at the problems referred to above, and a kind of arc extinguishing structure that has flash barrier is provided.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of breaker arc extinguishing structure that has flash barrier comprises arc control device, and the rear of arc control device is provided with the steam vent passage, it is characterized in that: flash barrier is installed at the steam vent passage place at described arc control device rear.
Described flash barrier is metalwork, and is S-shaped, has mesh on it.
The utility model has the advantages that: when dynamic and static contact breaking current, arcing is introduced into arc control device.Cut off through the arc control device arc extinguishing grid pieces, remaining electric arc by flash barrier, is cut off into section by the flash barrier sheet again, has increased the contact area of electric arc and air, and fast Absorption and cooling electric arc carry out the secondary arc extinguishing, reduce arc light in a large number and escape.The mesh of flash barrier can be tackled the spray slag that the inner arc extinguishing of circuit breaker produces simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model in circuit breaker;
Fig. 2 is an axonometric drawing of the present utility model.
Embodiment
Be described further below in conjunction with accompanying drawing.
The utility model relates to the breaker arc extinguishing structure that has flash barrier.
As shown in Figure 1, the utility model comprises arc control device 5, at the rear of arc control device 5, and steam vent passage place's design and installation flash barrier 6 of Shell of circuit breaker.As shown in Figure 2, flash barrier 6 is metalwork, and is S-type, has mesh on it.
When the moving contact 1 of circuit breaker during with fixed contact 2 breaking currents, the electric arc that produces between contact is guided arc control device 5 into by moving contact 1, fixed contact 2, flash barrier 3 (totally two, each a slice) up and down, striking sheet 4.Arcing sprays to the S type flash barrier 6 that is arranged on steam vent passage place after the arc extinguishing grid pieces of arc control device 5 cuts off, cools off.Under the effect of S type flash barrier 6, carry out the secondary arc extinguishing.Through above-mentioned processing, arcing is cooled off fast, and arc light escapes minimizing, and circuit breaker inside is filtered through the spray slag that high temperature produces, thereby has protected circuit breaker, increases the useful life of circuit breaker, eliminates and uses hidden danger.
Above-mentioned execution mode of the present utility model has been carried out detailed explanation,, can implement technical solutions of the utility model according to above-mentioned narration for those skilled in the art.
Claims (2)
