Abstract
The invention discloses a high-voltage circuit breaker which comprises a bottom plate, a handle, a moving contact, a static contact and a support frame, wherein the handle is fixed on the moving contact; a connecting shaft is arranged between the moving contact and the support frame; the static contact is fixed on the support frame; the support frame is fixed on the bottom plate; and the moving contact adopts a double-sheet duplex copper bar. The high-voltage circuit breaker has improved electrical conductivity and is suitable for high-voltage current.
Description
Technical field
The present invention relates to a kind of field of switches, relate in particular to a kind of high-tension line cutout.
Background technology
Knife switch is modal separation or drop into the equipment of load in the present power circuit, uses very extensively.The tradition knife switch generally includes ceramic wafer (seat), handle, contact knife, contact knife support, inlet wire connector assembly, connector assembly and protective cover occur, the inlet wire connector assembly with connector assembly occurs and be separately fixed at the ceramic wafer two ends, the contact knife support is fixed in the middle part of the ceramic wafer; The handing-over of contact knife one end is on the contact knife nail; The contact knife frame bottom is connected with lug plate through screw, the outlet connector assembly comprise lug plate and be enclosed within on the lug plate, the cross section becomes the degree of lip-rounding to be provided with the lead fastening frame of housing pin, the inlet wire connector assembly comprises that lead fastening frame, brace and cross section are the contact that triangular shape, open top elasticity clamp substantially; Lug plate wherein all is to lean on screw to connect to compress with contact knife support and brace with being connected of contact; Because lug plate can only accomplish that with the surface between contact knife support and the contact part contacts, contact resistance is bigger, poor electric conductivity; Therefore when big electric current flows through for a long time; Will generate heat, and then cause fault to occur, influence ordinary production.
Summary of the invention
The object of the present invention is to provide a kind of high-tension line cutout, increased conductivity, be fit to high-tension current and use.
Technical scheme of the present invention is: a kind of high-tension line cutout; Comprise base plate, handle, moving contact, fixed contact, support; Said handle is fixed on the moving contact, is provided with connecting axle between said moving contact and the support, and said fixed contact is fixed on the support; Said support is fixed on the base plate, and said moving contact adopts the compound copper bar of biplate.
In preferred embodiment of the present invention, said moving contact inboard is provided with spring.
In preferred embodiment of the present invention, said fixed contact is provided with guide hook.
In preferred embodiment of the present invention, said support is to process with porcelain vase.
According to the inventionly increased conductivity, be fit to high-tension current and use for a kind of high-tension line cutout.
Description of drawings
Accompanying drawing 1 is the perspective view of high-tension line cutout one preferred embodiment of the present invention.
The mark of each parts is following in the accompanying drawing: 1, base plate, 2, handle, 3, moving contact, 4, fixed contact, 5, support, 6, connecting axle, 7, guide hook.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
According to the invention is a kind of high-tension line cutout, referring to Fig. 1.A kind of high-tension line cutout; Comprise base plate 1, handle 2, moving contact 3, fixed contact 4, support 5, said handle 2 is fixed on the moving contact 3, is provided with connecting axle 6 between said moving contact 3 and the support 4; Said fixed contact 4 is fixed on the support 5, and said support 5 is fixed on the base plate 1.
Further, said moving contact 3 inboards are provided with spring.
Further, said fixed contact 4 is provided with guide hook.
Further, said support 5 is to process with ceramic material.
In one embodiment, according to the invention is a kind of high-tension line cutout, comprises base plate, handle, moving contact, fixed contact, support; Said handle is fixed on the moving contact, is provided with connecting axle between said moving contact and the support, and said fixed contact is fixed on the support; Said support is fixed on the base plate, and said moving contact adopts the compound copper bar of biplate, and said moving contact inboard is provided with spring; Said fixed contact is provided with guide hook, and said support is that porcelain vase is processed.When energising, the guide hook of fixed contact embeds the copper bar of moving contact and since spring elasticity make moving contact and fixed contact better inlay clamping, high-tension line cutout of the present invention has increased conductivity, is fit to the high-tension current use.
Embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claims were limited.
