Abstract
The utility model discloses a high voltage line current breaker, comprising a base plate, a handle, a moving contact, a static contact and a support. The handle is fixed on the moving contact; a connection shaft is provided between the moving contact and the support; the static contact is fixed on the support which is fixed on the base plate; the moving contact employs a double sheet compound copper bar. The high voltage line current breaker is provided with conductivity and is suitable for high voltage current.
Description
Technical field
The utility model relates to a kind of field of switches, relates 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.
The utility model content
The purpose of the utility model is to provide a kind of high-tension line cutout, has increased conductivity, is fit to high-tension current and uses.
The technical scheme of the utility model 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 utility model, said moving contact inboard is provided with spring.
In preferred embodiment of the utility model, said fixed contact is provided with guide hook.
In preferred embodiment of the utility model, said support is to process with porcelain vase.
The utility model is said to have increased conductivity for a kind of high-tension line cutout, is fit to high-tension current and uses.
Description of drawings
Accompanying drawing 1 is the perspective view of the utility model high-tension line cutout one preferred embodiment.
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 the preferred embodiment of the utility model is set forth in detail, thereby the protection range of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
The utility model is said to be 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, the utility model is said to be 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, the high-tension line cutout of the utility model has increased conductivity, is fit to the high-tension current use.
The embodiment of the utility model; But the protection range of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model disclosed; Variation or the replacement that can expect without creative work all should be encompassed within the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion with the protection range that claims were limited.
