Abstract
The invention provides an improved paper insulation self-adhesive enameled composite conductor, which solves the problems of low pressure resistance and low safety coefficient in the conventional paper insulation self-adhesive enameled composite conductor and can solve the problem that a self-adhesive paint layer of the conventional paper insulation self-adhesive enameled composite conductor is difficult to coat and process and has low processing efficiency. The composite conductor comprises at least two enameled flat wires, wherein the at least two enameled flat wires are combined on wide surfaces along an axial direction and are coated with a paper insulating layer; each enameled flat wire comprises a conductor; acetal paint is coated at the periphery of the conductor; a self-adhesive layer is arranged between an acetal paint surface of adjacent two enameled flat wires; and the composite conductor is characterized in that: the self-adhesive layer comprises a substrate layer, wherein epoxy resin with a self-adhesive function is uniformly coated on the upper surface and lower surface of the substrate layer.
Description
Technical field
The present invention relates to enamel-cover composite conductor technical field, be specially improved paper insulation self-adhesion enamel-cover composite conductor.
Background technology
Existing paper insulation self-adhesion enamel-cover composite conductor, it is axial by several self-adhesion enameled sheet wires, outsourcing insulation is made after wide the combination, its cross section structure is seen Fig. 1, composite conductor among Fig. 1 is axial by three self-adhesion enameled sheet wires, outsourcing insulating paper 4 is made after wide the combination, wherein the self-adhesion enameled sheet wire comprises conductor 1, conductor 1 outer peripheral face is coated with acetal enamelled coating 2, scribble self-adhesion enamelled coating 3 on the contact-making surface of the acetal enamelled coating 2 of adjacent self-adhesion enameled sheet wire, the width of self-adhesion enamelled coating 3 is generally 1/3～2/3 of conductor 1 width, its shortcoming is: the smearing processing and need adopt special mould to carry out operation of its self-adhesion lacquer, self-adhesion enamelled coating smearing thickness is inhomogeneous, width is inconsistent, makes that the adhesion strength of self-adhesion enamelled coating is low; Simultaneously because its self-adhesive layer width only is 1/3～2/3 of a conductor width, adjacent two enameled sheet wires do not separate fully, when adopting this composite conductor to carry out the coiling of coil, because the skin-friction coefficient of self-adhesion enamelled coating is big, make between the adjacent enameled sheet wire of composite conductor that play is easy to generate friction mutually, especially wide both sides of enameled sheet wire are not coated with the part of self-adhesion enamelled coating, and easily friction is impaired for the outer acetal paint film of enameled sheet wire conductor, thereby has the hidden danger of withstand voltage properties difference; And self-adhesion enamelled coating itself does not have insulating effect, and adjacent enameled sheet wire friction, the impaired back of acetal paint film easily produce short circuit, and coefficient of safety is low; And when composite conductor is combined by the enameled sheet wire more than three or three, except lower surface, the upper surface of upper and lower two enameled sheet wires is that single face is coated with the self-adhesion lacquer, the enameled sheet wire of all the other middle parts all needs the two-sided self-adhesion enamelled coating of smearing, it is big that it smears self-adhesion lacquer difficulty by die methods, painting quality is difficult to control, and working (machining) efficiency is low.
Summary of the invention
At the problems referred to above, the invention provides improved paper insulation self-adhesion enamel-cover composite conductor, it solves the problem that withstand voltage properties is poor, coefficient of safety is low in the existing paper insulation self-adhesion enamel-cover composite conductor, and can solve the self-adhesion enamelled coating that has paper insulation self-adhesion enamel-cover composite conductor now and smear the problem that difficulty of processing is big, working (machining) efficiency is low.
Its technical scheme is such, it comprises at least two enameled sheet wires, described at least two enameled sheet wires vertically, paper wrapper insulating barrier after wide combination, described enameled sheet wire comprises conductor, described conductor outer peripheral face is coated with acetal paint, be provided with self-adhesive layer between the acetal lacquer painting of adjacent described two enameled sheet wires, it is characterized in that: described self-adhesive layer comprises basalis, and upper and lower two surfaces of described basalis are coated with the epoxy resin with self-adhesion equably.
It is further characterized in that: described self-adhesive layer width is slightly less than described conductor width, and described self-adhesive layer width is than the little 0mm ~ 2mm of described conductor width; Described basalis is insulating paper or insulation film.
Compare with existing paper insulation self-adhesion enamel-cover composite conductor, beneficial effect of the present invention is: its self-adhesive layer comprises basalis, and the upper and lower surface of basalis is coated with the epoxy resin with self-adhesion, thereby can guarantee that self-adhesive layer thickness is even, width is consistent, and then improve the adhesion strength of self-adhesive layer; And the width of self-adhesive layer is more smaller than conductor width, thereby can guarantee that self-adhesive layer separates adjacent two enameled sheet wires fully avoids the play that produces each other and causes friction, the acetal enamelled coating of protection enameled sheet wire is difficult for impaired, improved the withstand voltage properties of composite conductor, also reduced simultaneously between adjacent enameled sheet wire because of the impaired phenomenon that produces short circuit of acetal enamelled coating, improved the peaceful property of composite conductor; In addition, it adopts insulating paper or the insulation film basalis as self-adhesive layer, because insulating paper or insulation film itself have insulating effect, thereby it also can play the effect of reinforced insulation, the fail safe that further improves composite conductor; In addition, the self-adhesive layer among the present invention only needs lining to be loaded between adjacent two enameled sheet wires, and it is easy to process, can improve working (machining) efficiency greatly.

Embodiment
Improved paper insulation self-adhesion enamel-cover composite conductor of the present invention, it comprises at least two enameled sheet wires, include three enameled sheet wires among Fig. 2 of present embodiment, three enameled sheet wires vertically, paper wrapper insulating barrier 4 after wide the combination in cross section, enameled sheet wire comprises conductor 1, conductor 1 outer peripheral face is coated with acetal paint 2, be provided with self-adhesive layer 7 between the acetal lacquer painting of two adjacent enameled sheet wires, see Fig. 3, wherein self-adhesive layer comprises basalis 5, upper and lower two surfaces of basalis 5 are coated with epoxy resin 6 equably, and basalis 5 is insulating paper or insulation film.The self-adhesive layer lining is loaded between the acetal lacquer painting of adjacent two enameled sheet wires, and self-adhesive layer 7 width are than the smaller 0 ~ 2mm of the width of conductor 1.Generally, be 0.02mm～0.125mm as the insulating paper of basalis or the thickness of insulation film, the thickness that plays the two-sided epoxy resin layer of self-adhesion is 0.015 mm ~ 0.03mm, the thickness of whole self-adhesive layer 7 is 0.03mm～0.155mm.
