Abstract
The utility model provides an enameled flat wire with a single-side enameled self-adhesive layer, which consists of a bare copper flat wire, an enameled insulation layer and a self-adhesive layer. Only two wide sides of the enameled flat wire are provided with the self-adhesive layer, while the two narrow sides of the enameled flat wire are not provided with the self-adhesive layer. The utility model increases the adhesive strength by 20 percent without blockage of the oil duct, improves the cooling function of the transformer coil, enhances the anti-short-circuit capacity of the transformer coil, ensures the quality of the transformer, prolongs the service life of the transformer by 5 to 10 years, reduces the axial height of the transformer coil, decreases the size of the transformer, and reduces the production cost of the transformer plant.
Description
Technical field
The utility model relates to a kind of single enameled sheet wire that is applied to the coiling used in transformer coil, is meant a kind of enameled sheet wire of strengthening the self-adhesive layer single-face lacquering of coil anti-short circuit capability and oil duct heat sinking function especially.
Background technology
The single enameled sheet wire of the tack transposed conductor that the high-power transformer coil winding of domestic production is at present used, all adopt the width limit all to be coated with the self-adhesion lacquer, can make through the transposed conductor after the vacuumize and bond together, thereby increase the mechanical strength of transformer under short-circuit condition, improve the anti-short circuit capability of transformer.But it is big that the transformer coil axial dimension becomes, and production cost increases; And oil duct stops up, and can influence the heat sinking function of transformer coil, and partial discharge of transformer strengthens, and reduces transformer service life.
Summary of the invention
The purpose of this utility model just is to overcome the defective of background technology, and a kind of enameled sheet wire of strengthening the low self-adhesive layer single-face lacquering of coil anti-short circuit capability and oil duct heat sinking function and production cost is provided.
The purpose of this utility model is realized by following scheme:
The utility model is made of bare copper flat wire (being copper conductor), insulating barrier and self-adhesive layer, only on two broadsides of enameled sheet wire self-adhesive layer is arranged, and does not have self-adhesive layer on two narrow limits of enameled sheet wire.
The utility model self-adhesive layer is an epoxy paint film self-adhesive layer.
The monolateral thickness of the utility model self-adhesive layer is 0.01mm-0.045mm.
The width of the utility model self-adhesive layer is less than or equal to 2/3rds of enameled sheet wire width edge length.
The width of the utility model self-adhesive layer is 1mm-10mm.
The utility model insulating barrier is an acetal paint film insulating barrier.
The utility model is compared with background technology, has following advantage and effect:
Adhesion strength strengthens 20%.Can not stop up oil duct, improve the heat sinking function of transformer coil, strengthen the anti-short circuit capability of transformer coil, both guaranteed the quality of transformer, prolonged transformer service life 5-10, the transformer coil axial height is reduced, volume of transformer diminishes, and reduces the production cost of transformer factory.Therefore, the utility model has excellent popularization and application prospect as a kind of enameled sheet wire of novel self layer single-face lacquering.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Shown in the figure: 1 is that bare copper flat wire (also claiming copper conductor), 2 is that acetal paint film insulating barrier, 3 is epoxy paint film self-adhesive layer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.The utility model is not limited to following examples.
With reference to accompanying drawing, the utility model also claims copper conductor (1), acetal paint film insulating barrier (2) to constitute with epoxy paint film self-adhesive layer (3) by bare copper flat wire.The outside of bare copper flat wire (1) is an acetal paint film insulating barrier (2).For preventing that epoxy viscose from stopping up oil duct, the outside of acetal paint film insulating barrier (2), epoxy paint film self-adhesive layer (3) is only arranged on two broadsides, the width of epoxy paint film self-adhesive layer (3) is 1mm-10mm, (or be less than or equal to enameled sheet wire width edge length 2/3rds), the monolateral thickness of epoxy paint film self-adhesive layer (3) is 0.01mm-0.045mm (bilateral thickness is 0.02mm-0.09mm).Its technological process of production is: bare copper wire unwrapping wire-softening is anti-oxidation-be coated with acetal Q coat with lacquer-to cure-and the monolateral self-adhesion lacquer H-cure-the finished product take-up of being coated with.
Claims (6)
1, a kind of enameled sheet wire of self-adhesive layer single-face lacquering is made of bare copper flat wire (1), insulating barrier (2) and self-adhesive layer (3), and it is characterized in that has self-adhesive layer (3) on two broadsides of enameled sheet wire, does not have self-adhesive layer (3) on two narrow limits of enameled sheet wire.
2, the enameled sheet wire of self-adhesive layer single-face lacquering according to claim 1 is characterized in that self-adhesive layer is an epoxy paint film self-adhesive layer (3).
3, the enameled sheet wire of self-adhesive layer single-face lacquering according to claim 1 and 2, the monolateral thickness that it is characterized in that epoxy paint film self-adhesive layer (3) is 0.01mm-0.045mm.
4, the enameled sheet wire of self-adhesive layer single-face lacquering according to claim 3 is characterized in that the width of self-adhesive layer (3) is less than or equal to 2/3rds of enameled sheet wire width edge length.
5, the enameled sheet wire of self-adhesive layer single-face lacquering according to claim 3, the width that it is characterized in that epoxy paint film self-adhesive layer (3) is 1mm-10mm.
6, the enameled sheet wire of self-adhesive layer single-face lacquering according to claim 1 is characterized in that insulating barrier is an acetal paint film insulating barrier (2).
