Abstract
The invention discloses an electrically-driven DC motor enamelled rectangular section conductor, which comprises a flat copper core wire (1). The flat copper core wire (1) is provided with a polyimide enamelled layer (2), a nylon surface layer (3), a glass fiber layer (4) and an insulated varnish layer (5) from inside to outside. The insulated varnish applied to the surface of the insulated varnish layer (5) is composed of the following components: by weight parts, 30 to 50 parts of polyimide, 20 to 30 parts of organic silicon resin, 1 to 5 parts of glass fiber, 1 to 3 parts of nanometer titania, 5 to 10 parts of mica powder, 2 to 6 parts of linseed oil and 10 to 15 parts of antimony trioxide. As the electrically-driven DC motor enamelled rectangular section conductor comprises the flat copper core wire, the polyimide enamelled layer, the nylon surface layer, the glass fiber layer and the insulated varnish layer sequentially from inside to outside, the insulated varnish is prepared by polyimide, organic silicon resin and the like, the enamelled rectangular section conductor has excellent high temperature-resisting performance and insulated performance, the glass fiber layer improves the use strength of the enamelled rectangular section conductor, and the service life is long.
Description
Technical field
The invention belongs to technical field of electric wires and cables, specifically a kind of electric drive direct current machine enameled sheet wire.
Background technology
Enamelled wire is primarily of conductor layer and insulating barrier two parts composition, in the development course of enamelled wire, adopt the conductor cores of pure copper material the earliest, then improving later enamelled wire adopts copper clad aluminum material to replace pure copper material as conductor cores, this kind of thread coiling group of enamel-cover or coil, its heat resistance is poor, solvent resistance is weak, enamelled coating is easily aging, and existing enamelled wire mainly uses as winding wire, but existing enamelled wire is all toroidals, relatively cunning, can be neat not during winding, fixing firm not, easy breakage, and its outside of existing enamelled wire just scribbles insulating barrier, the intensity of its line is not high, and anti-corrosive insulation effect is general.
The enameled sheet wire be applied on New energy electric big bus electric drive direct current machine will use usually under long-time energising and the condition rubbed, wire enamel conventional at present can not meet the aging and wear-resisting loss of continuous high temperature, cause enamelled wire easily damage and conduct electricity, affect the normal work of machine.The enameled sheet wire being exclusively used in motor of prior art easily damages under the high temperature conditions.
Summary of the invention
The object of the present invention is to provide a kind of electric drive direct current machine enameled sheet wire.
Object of the present invention can be achieved through the following technical solutions:
A kind of electric drive direct current machine enameled sheet wire, it is characterized in that, comprise flat copper heart yearn, described flat copper heart yearn is provided with polyimides enamelled coating, nylon surface layer, glass fiber layer and insulating lacquer layer from inside to outside, and each ingredients weight parts of the insulating varnish of described insulating lacquer layer surface-coated consists of: polyimides 30-50 part, organic siliconresin 20-30 part, glass fibre 1-5 part, nano titanium oxide 1-3 part, mica powder 5-10 part, linseed oil 2-6 part, antimonous oxide 10-15 part.
As preferred further, nylon surface layer epoxy resin-impregnated 20-30min of the present invention.
As preferred further, each ingredients weight parts of insulating varnish of the present invention consists of: polyimides 40 parts, organic siliconresin 25 parts, 3 parts, glass fibre, nano titanium oxide 2 parts, mica powder 8 parts, linseed oil 4 parts, antimonous oxide 12 parts.
Beneficial effect of the present invention: a kind of electric drive direct current machine of the present invention enameled sheet wire is followed successively by flat copper heart yearn, polyimides enamelled coating, nylon surface layer, glass fiber layer and insulating lacquer layer from inside to outside, insulating varnish is prepared by polyimides, organic siliconresin etc., enameled sheet wire of the present invention has excellent resistance to elevated temperatures, insulation property, glass fiber layer improves the working strength of enameled sheet wire, long service life.
