Abstract
The utility model discloses the static contact system in a kind of low-voltage circuit breaker, it comprises joint cover, insulating barrier, fixed contact torsion spring, rivet, fixed contact, contact, shock wave reflection plate, stationary contact bracket, axle, is flexible coupling, weld by being flexible coupling between joint cover with fixed contact, contact is welded with fixed contact, fixed by rivet after fixed contact and shock wave reflection sleeve-board connect, axle is through fixed contact torsion spring, shock wave reflection plate, stationary contact bracket, stationary contact bracket is arranged on insulating barrier, and insulating barrier is positioned on joint cover.The utility model improves fail safe during disjunction, again saves cost, is more conducive to arc extinguishing when circuit breaker disjunction.
Description
Technical field
The utility model relates to a kind of static contact system, particularly relates to the static contact system in a kind of low-voltage circuit breaker.
Background technology
Existing fixed contact is from front end cabling; need with the protection of tetrafluoro glass cloth; when preventing disjunction, electric arc causes the scaling loss be flexible coupling, and also will adjust not so tetrafluoro glass cloth when installing and can not protect completely and put in place, and not in placely cause the scaling loss be flexible coupling once protect, whole circuit breaker will be scrapped.Existing fixed contact does not have shock wave reflection plate less for the help of disjunction.
Utility model content
Technical problem to be solved in the utility model is to provide the static contact system in a kind of low-voltage circuit breaker, its
The utility model solves above-mentioned technical problem by following technical proposals: the static contact system in a kind of low-voltage circuit breaker, it is characterized in that, it comprises joint cover, insulating barrier, fixed contact torsion spring, rivet, fixed contact, contact, shock wave reflection plate, stationary contact bracket, axle, be flexible coupling, weld by being flexible coupling between joint cover with fixed contact, contact is welded with fixed contact, fixed by rivet after fixed contact and shock wave reflection sleeve-board connect, axle is through fixed contact torsion spring, shock wave reflection plate, stationary contact bracket, stationary contact bracket is arranged on insulating barrier, insulating barrier is positioned on joint cover.
Preferably, the side of described stationary contact bracket is provided with stationary contact bracket protective cover.
Preferably, one end of described joint cover is provided with through hole.
Positive progressive effect of the present utility model is: the utility model, from rear end cabling, can not re-use tetrafluoro glass cloth, namely improves fail safe during disjunction, again saves cost, adds shock wave reflection plate, is more conducive to arc extinguishing when circuit breaker disjunction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the static contact system in the utility model low-voltage circuit breaker.
Fig. 2 is the structural representation that the utility model increases stationary contact bracket protective cover.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, static contact system in the utility model low-voltage circuit breaker comprises joint cover 1, insulating barrier 2, fixed contact torsion spring 3, rivet 4, fixed contact 5, contact 6, shock wave reflection plate 7, stationary contact bracket 8, axle 9, be flexible coupling 10, 10 to weld by being flexible coupling between joint cover 1 with fixed contact 5, contact 6 is welded with fixed contact 5, fixed by rivet 4 after fixed contact 5 and shock wave reflection plate 7 are socketed, axle 9 is through fixed contact torsion spring 3, shock wave reflection plate 7, stationary contact bracket 8, stationary contact bracket 8 is arranged on insulating barrier 2, insulating barrier 2 is positioned on joint cover 1.
The side of stationary contact bracket 8 is provided with stationary contact bracket protective cover 11, and such stationary contact bracket protective cover can protect stationary contact bracket.
One end of joint cover 1 is provided with through hole 12, so conveniently positions or fixes.
Installation process of the present utility model is as follows: first fixed contact 5 and contact 6 weld together, then with joint cover 1 with together with 10 welding again that are flexible coupling, ensure current lead-through.Shock wave reflection plate 7 and fixed contact 5 are nested together, also wear also riveting together with rivet 4.Then the part installed is added upper static contact torsion spring 3 and stationary contact bracket 8 to be stitched together hole alignd, with axle 9, these parts are worn.The part installed is placed on insulating barrier 2, then is placed on joint cover 1.Then the fixed contact installed is whole to be placed on pedestal, is accomplished fluently by screw, and finally install in stationary contact bracket 8 by stationary contact bracket protective cover 11, whole installation all completes.
Because the cabling be flexible coupling is walked in rear end, not in front end so eliminate tetrafluoro glass cloth, protect the such fail safe of joint cover greatly to improve with insulating barrier, do not worry that tetrafluoro glass cloth is burnt and installs not in place the caused scaling loss be flexible coupling.The spacing of cocked position of fixed contact is located by stationary contact bracket, is axle location in the past, and if axle generation deformation, easily causes location inaccurate, and then affect the excess of stroke and end pressure.With after shock wave reflection plate when disjunction, due to this reflecting plate nylon material, can produce a large amount of gas, these gases can help arc extinguishing.Fixed contact protective cover can protect being flexible coupling of rear end, and when also can reduce disjunction, metallic enters switch rear portion.
Above-described specific embodiment; the technical problem of solution of the present utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
