Detailed Description
In order to make the purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the embodiments described below are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical scheme of the application is further explained by the specific implementation mode in combination with the attached drawings.
In the description of the present application, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present application.
The arc-quenching chamber 20 that relates in this application is used for replacing the arc-quenching chamber 20 among the existing structure circuit breaker, for current arc-quenching chamber 20, the integrative assembly of adoption among the arc-quenching chamber 20 of this application, because the reason of self structure, in the shell is directly adorned to the top-down of arc-quenching piece 22, forms arc-quenching chamber 20 at last. The arc extinguishing chamber 20 is directly arranged on the circuit breaker, and the arc extinguishing chamber 20 is also arranged in the circuit breaker from top to bottom, so that the arc extinguishing piece 22 cannot drop or be replaced independently, and the safety of the arc extinguishing piece 22 element is ensured.
In the prior art, a plurality of arc extinguishing plates 22 are arranged in the arc extinguishing chamber 20 in a front-back mode, and then a protective shell is additionally arranged on the outer side. Secondly, the circuit breaker is sometimes not horizontally placed and may be vertically placed, so that the gravity direction is consistent with the loading direction of the arc quenching sheet 22, and the circuit breaker may suddenly drop after long-term use, thereby affecting the arc quenching effect.
In this application, the direct installation orientation change that will extinguish arc piece 22, top-down assembly, one end offsets by the base of extinguishing chamber 20, and the other end offsets with the part of the circuit breaker of installing to whole device's firm degree has been improved.
As a specific example, four sets of limiting parts are arranged in the arc quenching chamber 20 of the present application, and three arc quenching plates 22 are provided, and the arc quenching effect is not significantly increased by the addition of the arc quenching plates 22.
The end of the limiting element 25 facing the arc extinguishing piece 22 is set to be arc-shaped to achieve a better clamping effect, and the arc-shaped mainly has a small contact area with the arc extinguishing piece 22, but can still achieve clamping.
The longitudinal section of arc extinguishing piece 22 is the U type in this application, is provided with a plurality of meshs 21 in the arc extinguishing piece 22 to realize the effect of putting out the arc, mesh 21 evenly distributed in this application.
The arc extinguishing piece 22 is made of a steel plate, and a nickel plating layer is arranged on the surface of the arc extinguishing piece 22, so that the arc extinguishing effect is further improved.
The utility model provides a room 20 of putting out arc when the equipment, inserts the arc extinguishing piece 22 between the locating part 25 with top-down earlier, because the width between the locating part 25 is not more than the width of the arc extinguishing piece 22, the effect that differs about 0.1mm is better in practice, can be with the more stable fixed of arc extinguishing piece 22, also can not take place to warp, and the ability of adsorbing the ion can effectively be guaranteed, and it is effectual to put out the arc. The arc extinguishing piece 22 adopts a U-shaped structure, so that later-stage replacement is facilitated, the independent arc extinguishing piece 22 is directly replaced, all the arc extinguishing pieces 22 in the whole arc extinguishing chamber 20 are not required to be replaced, secondly, the surface area is almost not changed, and the arc extinguishing effect is guaranteed.
The foregoing is only a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present application, and these modifications and variations should also be considered as the protection scope of the present application.
