According to the technical scheme provided by the utility model, the waterproof polyimide sintered membrane wrapping transposed conductor comprises an oxygen-free copper flat wire conductor, wherein the outer surface of the oxygen-free copper flat wire conductor is polished and is sequentially coated with a waterproof adhesive film layer and a polyimide basilemma layer to form a single wire of a transposed conductor core; the single wire of a transposed conductor core is arranged into two columns with narrow edges mutually being in contact with each other and forms an integrated wire through conversion, and a high temperature resistant insulating layer is wound around the integrated wire into a whole. The waterproof polyimide sintered membrane wrapping transposed conductor has the advantages of high temperature resistance, high voltage resistance, good anti-corona performance and water repellency, strong applicability and long service life.
Description
Technical field
The utility model relates to a kind of transposed conductor, and especially a kind of waterproof polyimide sintered membrane-covered transposition conductor belongs to the coil windings technical field.
Background technology
In prior art, transformer high temperature resistant, anti-corona type is to adopt the single paint film structure or the transposed conductor of polyimides F-46 composite film with the low-voltage coil winding wire.Adopt the transposed conductor of said structure to have following shortcoming: the first, the transposed conductor of single paint film structure, if adopt moisture resistance wet type insulating varnish, its high temperature resistant, high pressure resistant, anti-corona poor performance; If adopt high temperature resistant, high pressure resistant, anti-corona performance insulating varnish, it is to the tack extreme difference of copper conductor.Therefore, when Transformer Winding was born instantaneous pressure impact, the impact of high mechanical stress and adverse circumstances impact, all there were defective in the safety in operation of transposed conductor and protection.Second, the transposed conductor of polyimides F-46 composite film, though on the material serviceability, can solve high temperature resistant, high pressure resistant, anti-corona and moisture resistance, but if adopt traditional compound around-packing technology of polyimides F-46 film, there are bubble and gauffer in film envelope curve surface, film is attached with discontinuity and pin hole point to conductor, can influence the trouble free service and the useful life of transformer equally.These domestic transposed conductor performances are restricting the design and the manufacturing of High-Speed Freight Vehicle electric locomotive group, and therefore, the invention waterproof polyimide sintered membrane-covered transposition conductor has belonged to that time and tide wait for no man.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of waterproof polyimide sintered membrane-covered transposition conductor is provided, and it is high temperature resistant, high pressure resistant, anti-corona and good waterproof performance, and applicability is strong, long service life.
According to the technical scheme that the utility model provides, a kind of waterproof polyimide sintered membrane-covered transposition conductor comprises oxygen-free copper lenticular wire conductor; The outer surface of described oxygen-free copper lenticular wire conductor carries out polishing with aluminium oxide or nylon, coated insulation marine glue rete and polyimide-based rete successively again, form the single line of transposed conductor core, two row that the single line assortment of described transposed conductor core becomes narrow limit to be in contact with one another, form whole bunch through transposition, outside whole bunch, twine temperature-resistant insulation layer and form one.
Polishing is carried out with aluminium oxide or nylon in described copper conductor surface.The thickness of described insulative water-proof glue-line is 0.128～0.132mm.Described polyimide-based rete be thickness 0.245～0.255mm.The thickness of described temperature-resistant insulation layer is 0.35～0.45mm.
Advantage of the present utility model: project organization compactness, reasonable, water-fast, high temperature resistant, high pressure resistant, anti-corona, the anti-high mechanical properties performance of winding wire significantly improve.The coil decapacitation of coiling stands outside the performance of anti-high-frequency impulse peak voltage impact and corona resistance aspect, can also stand to drench with rain, soak, the impact of adverse circumstances such as heat vaporization, applicability is strong, has improved the function of use and the useful life of traction power transformer and motor.

Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the utility model is made up of oxygen-free copper lenticular wire conductor 1, insulative water-proof adhesive film 2, polyimide-based rete 3 and temperature-resistant insulation layer 4.
The outer surface of described oxygen-free copper lenticular wire conductor 1 carries out polishing with aluminium oxide or nylon.The outer surface of described oxygen-free copper lenticular wire conductor 1 is coated insulation marine glue rete 2 and polyimide-based rete 3 successively, form the single line of transposed conductor core, two row that the single line assortment of described transposed conductor core becomes narrow limit to be in contact with one another, form whole bunch through transposition, outside whole bunch, twine temperature-resistant insulation layer 4 and form one.
The thickness of described insulative water-proof glue-line is 0.128～0.132mm.Described polyimide-based rete be 0.245～0.255mm.The thickness of described temperature-resistant insulation layer is 0.35～0.45mm.
Add man-hour, described oxygen-free copper lenticular wire conductor 1 is aligned shaping behind continuously extruded high-temperature molding.Use aluminium oxide, carborundum or nylon that polishing is carried out on the surface of oxygen-free copper lenticular wire conductor 1.Insulative water-proof adhesive film 2, polyimide-based rete 3 are coated on successively on the outer surface of oxygen-free copper lenticular wire conductor 1, behind electromagnetic wire HF induction heating apparatus sintering, be bonded on the oxygen-free copper lenticular wire conductor 1 after insulative water-proof adhesive film 2,3 fusions of polyimide-based rete, after insulative water-proof adhesive film 2, polyimide-based rete 3 are closely tied with oxygen-free copper lenticular wire conductor 1 after the roll compaction, together, form single waterproof polyimide sintering membrane-covered flat wire after after the boiler water circulation cooling, promptly drying up with strong cold wind.Two row that single waterproof polyimide sintering membrane-covered flat wire becomes narrow limit to be in contact with one another all single line assortments in preset pitch, refer to that through two-way pushing away transposer carries out the little spring song of " S " type with waterproof polyimide sintering membrane-covered flat wire, coordinated transposition repeatly, knit into the Bundling conducting wire core, coat temperature-resistant insulation layer 4 then, through coil on after the pulling equipment compacting around waterproof polyimide sintered membrane-covered transposition conductor.
