Abstract
The utility model relates to a L -C epoxy coating stranded paper bag wire, including two piece at least varnished cloth ribbon lines, the varnished cloth ribbon line makes up back outsourcing paper insulation layer along axial, wide face, the varnished cloth ribbon line adopts the cross section to make for oval -shaped naked copper or the outer coating insulated paint membrane of aluminium ribbon line, and be equipped with the width between two adjacent varnished cloth ribbon lines and be 23 and epoxy self -adhesive layers of above varnished cloth ribbon line width, be provided with a plurality of segmentations and thickness on the space between varnished cloth ribbon line and the paper insulation layer only for 0.01mm's the 2nd epoxy self -adhesive layer. The utility model has the advantages of rational in infrastructure simple, manufacture easy, heat dispersion is good, small and saved material cost.
Description
Technical field
The utility model relates to a kind of electronic machines & apparatus paper using package and closes parallel wire, and specifically a kind of L-C epoxy coating multiply paper-covered wire, belongs to winding wire technical field.
Background technology
Existing paper insulation enamel-cover combined parallel wire be by several self-adhesion enameled sheet wire vertically, wide combination after paper wrapper insulating barrier make, and a lining paper layer is provided with further between adjacent two enameled sheet wires, be mainly used in oil-immersed type transformer, reactor and other electric equipments.Existing paper-covered wire, through repeatedly bending when coiling, and therefore outer field insulating paper easily weares and teares, and lining paper layer adds the integral thickness of paper-covered wire, and structure is complicated slightly, have impact on properties of product.Intermediate manufacturer has carried out an improvement to the paper-covered wire of this structure, change existing lining paper layer into complete coated epoxy resin, to reduce the integral thickness of paper-covered wire, but in the process of processing and manufacturing, easily causing large volume and forming bubble at the corner edge place of conductor because extruding, particularly at rounded edges place, the wire of this kind of structure can not be full of by transformer oil, thus likely produce fever phenomenon, and large area can be caused to generate heat, affect the serviceability of electric equipment or device and the useful life of wire.
Summary of the invention
The utility model, just for the technical problem existed in prior art, provides a kind of simple and reasonable, good insulation preformance, perfect heat-dissipating and the little L-C epoxy coating multiply paper-covered wire of volume.
To achieve these goals, the technical solution adopted in the utility model is, a kind of L-C epoxy coating multiply paper-covered wire, comprise at least two enameled sheet wires, described enameled sheet wire vertically, paper wrapper insulating barrier after wide combination, described enameled sheet wire adopts cross section to be that oval naked copper or flat aluminium wire apply insulation paint film outward and make, the first ring epoxy resins self-adhesive layer that width is 2/3 and above enameled sheet wire width is provided with between two adjacent enameled sheet wires, space between described enameled sheet wire and paper insulating layer is provided with some segmentations and thickness is only the second epoxy resin self-adhesive layer of 0.01mm.
Improve as one of the present utility model, described insulation paint film is good insulation preformance and the acetal paint film of heat resisting or polyester-imine/polyamide-imine composite paint film.
Improve as one of the present utility model, the thickness of described first ring epoxy resins self-adhesive layer is 0.03-0.08mm, and preferably, its thickness is set to 0.06mm.
Improve as one of the present utility model, described paper insulating layer be in cable paper, insulating material such as insulation crimped paper, heat proof cable paper, Dan Nisong paper, insulation film etc. any one or more combination.
Relative to prior art, the utility model has the advantage of, simply rational in infrastructure, manufacture easily, perfect heat-dissipating, volume is little and save material cost; Adopt the different first ring epoxy resins self-adhesive layer of thickness and the second epoxy resin self-adhesive layer to substitute traditional insulating bag paper, greatly can reduce the integral thickness of paper-covered wire; The setting of epoxy resin self-adhesive layer can improve the mechanical strength of adhesion strength between enameled sheet wire and between enameled sheet wire and paper wrapper insulating barrier and wire entirety, and the insulating effect that epoxy resin self-adhesive layer has itself, it also can play the effect of reinforced insulation, further strengthens the security performance of paper-covered wire; The lines of enameled sheet wire are arranged to arc, and the wearing and tearing from enameled sheet wire corner angle suffered when avoiding paper insulating layer outsourcing, substantially prolongs the useful life of paper-covered wire.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present utility model.
In figure: 1-enameled sheet wire, 2-paper insulating layer, 3-insulate paint film, 4-first ring epoxy resins self-adhesive layer, 5-second epoxy resin self-adhesive layer.
Embodiment
In order to deepen understanding and cognition of the present utility model, below in conjunction with accompanying drawing the utility model be further described and introduce.
As shown in Figure 1, a kind of L-C epoxy coating multiply paper-covered wire, comprises four enameled sheet wires 1, described enameled sheet wire 1 vertically, wide combination after paper wrapper insulating barrier 2.Described enameled sheet wire 1 adopts cross section to be that oval naked copper or flat aluminium wire apply insulation paint film 3 outward and make, be provided with the first ring epoxy resins self-adhesive layer 4 that width is 2/3 and above enameled sheet wire width between two adjacent enameled sheet wires 1, the thickness of described first ring epoxy resins self-adhesive layer 4 is set to 0.06mm.Space between described enameled sheet wire 1 and paper insulating layer 2 is provided with 10 segmentations and thickness is only the second epoxy resin self-adhesive layer 5 of 0.01mm, thus reduces the axial dimension of wire.Described insulation paint film 3 is good insulation preformance and the acetal paint film of heat resisting or polyester-imine/polyamide-imine composite paint film.In order to make paper-covered wire finished product have good heat-resisting and resistance to elevated temperatures, preferably, adopt polyester-imine/polyamide-imine composite paint film as the insulation paint film 3 of enameled sheet wire.The paper insulating layer 2 of outsourcing selects individual layer heat proof cable paper, to reduce the volume of wire further.The utility model structure is simple, improves insulation property and the security performance of paper-covered wire, even if paper wrapper wearout still has insulation effect.
It should be noted that above-described embodiment, be not used for limiting protection range of the present utility model, equivalents done on the basis of technique scheme or the alternative scope all falling into the utility model claim and protect.In the claims, first, second use of word does not represent any order, can be title by these word explanations.
