Abstract
The utility model discloses an arc extinguish chamber used for a molded case circuit breaker. The arc extinguish chamber used for the molded case circuit breaker comprises a case body and a number of U-shaped metal gate plates which are arranged at intervals in the case body. The case body comprises a top wall, a pair of side walls, a bottom wall and a front wall. The position, which is at a back wall, of the case body is an opening. The top wall and the bottom wall are respectively provided with a groove. A number of chutes which are relative to each other are arranged at intervals inside the pair of side walls. The arc extinguish chamber has the advantages of small volume, easy assembly, high arc extinguish performance and reduced production cost.
Description
Technical field
The utility model relates to the low-voltage electrical apparatus field, is specifically related to a kind of arc control device that are used for breaker of plastic casing.
Background technology
Most of moulded case circuit breakers all adopt traditional riveting type arc control device arc extinguishing in the industry at present, and the ultrapas laminated sheet is adopted in both sides.Guarantee its mechanical stability, need complicated procedure of processing, processing cost is high.
For this reason, we have designed little, the easy assembling of a kind of volume, and arc extinction performance is high, and the split mounting type arc control device that cost is low had both improved performance, had reduced cost again.
The utility model content
The utility model provides a kind of arc control device that are used for breaker of plastic casing, little, the easy assembling of this arc control device volume, and arc extinction performance is high and reduced production cost.
In order to achieve the above object, the utility model is realized through following technical scheme:
A kind of arc control device that are used for breaker of plastic casing are characterized in, comprise: housing and interval are arranged on the some U type metal gates sheets in the housing.
Described housing comprises roof, pair of sidewalls, diapire and antetheca, and this housing is made as opening in the rear wall position.
Described roof and diapire are respectively equipped with groove.
Described pair of sidewalls clear width is provided with some chutes respect to one another.
Described some U type metal gates sheets are inserted into respectively in the said chute.
A kind of arc control device that are used for breaker of plastic casing of the utility model compared with prior art have the following advantages:
Little, the easy assembling of this arc control device volume, arc extinction performance is high and reduced production cost.
Description of drawings
Fig. 1 is a kind of structural representation that is used for the arc control device of breaker of plastic casing of the utility model;
Fig. 2 is a kind of structural representation that is used for the arc control device of breaker of plastic casing of the utility model.
Embodiment
Below in conjunction with accompanying drawing,, the utility model is done further elaboration through specifying a preferable specific embodiment.
Like Fig. 1 ~ shown in Figure 2, a kind of arc control device that are used for breaker of plastic casing comprise: housing and be arranged on the some U type metal gates sheets 2 in the housing at interval.Housing is processed by insulating material, and described housing comprises roof 11, pair of sidewalls 12, diapire 13 and antetheca 14, and this housing is made as opening (promptly not being provided with rear wall) in the rear wall position.Described roof 11 and diapire 13 are respectively equipped with groove.Described pair of sidewalls 12 clear widths are provided with some chutes respect to one another 121.Described some U type metal gates sheets 2 are inserted into respectively in the said chute 121.
The arc quenching principle of arc control device is: in short circuit current dynamic/static contact separation process; The contact surface temperature excursion; Cause the ambient air discharge, because the free generation electric arc of gas, arc current space around produces magnetic flux; With 2 magnetization of U type metal gates sheet, U type metal gates sheet 2 produces a kind of suction of electric arc being drawn in arc control device.The short arc that is divided into many series connection behind the electric arc entering U type metal gates sheet 2; After the U type metal gates sheet 2 of original cold state is close to short arc, arc resistance is increased, arc voltage rises; When arc voltage during greater than the power frequency recovery voltage at contact two ends, electric arc has just been extinguished.
These arc control device are not established rear wall so that portion gas flows out, and have reduced the impact of gas to housing.Insert in the chute 121 through U type metal gates sheet 2, U type metal gates sheet 2 can not beated easily, thereby strengthen the mechanical stability of arc control device.By the arc control device that insulating material and U type metal gates sheet 2 are formed, its procedure of processing and processing technology are simple relatively, and almost enclosed housing to electric arc get into arc control device can be all timely and effectively arc extinguishing also play an important role, prevent that electric arc from overflowing outside the arc control device.
In sum, a kind of arc control device that are used for breaker of plastic casing of the utility model, little, the easy assembling of this arc control device volume, arc extinction performance is high and reduced production cost.
Although the content of the utility model has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to the restriction to the utility model.After those skilled in the art have read foregoing, for the multiple modification of the utility model with to substitute all will be conspicuous.Therefore, the protection range of the utility model should be limited appended claim.
