Description
Technical field
The utility model relates to a kind of enamelled wire.Particularly relate to a kind of enamel insulated aluminium wire.
Background technology
Day by day in short supply along with petroleum resources, the development of new-energy automobile is more and more subject to the attention of Ge great depot.New-energy automobile refers to other energy automobiles all except gasoline, Diesel engine.Comprise fuel cell car, hybrid vehicle, hydrogen-powered vehicles and solar telephone etc.But the no matter new-energy automobile of which kind of type, its motor is one of crucial parts as Power Drive Unit.Operation characteristic as the motor of automobile power is that power change is fast and frequent, and environment for use variations in temperature is large, therefore requires that it is stable, and overload capacity is strong, lightweight, temperature performance and good electrical property.
And on motor performance, there is important impact as the winding of the critical piece of motor, usual motor winding uses enamel-cover copper or enamel insulated aluminium wire, enamel covered wire price is high, processing technology is complicated, need secondary dipping lacquer, processing cost is high, and shield effectiveness is not very good, not resistant to partial discharges, corona-resistance property is also undesirable.
Enamel insulated aluminium wire has the freeze-resistant performance of excellent resistance to elevated temperatures, mechanical performance, electric property and chemical property and excellence, but, existing enamel insulated aluminium wire comprises mechanical performance prerequisite, chemical property, in the large performance of electrical property and hot property etc. four, its mechanical performance still has with the electrical property in certain situation the requirement improved.Such as in sizing, because its flexibility is had a surplus and rigidity is not enough, therefore winding sizing is not just can follow one's bent so.And in electric conductivity, under certain service condition, its load can be more weak, be difficult to meet some instructions for use.Its solderability is poor in addition, makes troubles to a certain extent to connection.
Utility model content
The purpose of this utility model is that the deficiency existed for above-mentioned prior art provides a kind of enamel insulated aluminium wire.This enamelled aluminum wire structure is reasonable, has both had good welding performance, and weight is light again, and has good electrical property and mechanical performance, and the coil of same volume or winding have better load capacity.
The technical solution of the utility model comprises aluminum steel main body, in described aluminum steel main body, central authorities are provided with layers of copper or interior silver layer in one deck, the outside wall surface of described aluminum steel main body is provided with outer layers of copper and/or outer silver layer, the outside wall surface of described outer layers of copper and/or outer silver layer is provided with insulating barrier, rounded or the rectangle of the shape of cross section of described aluminum steel main body, to be located in described aluminum steel main body the interior layers of copper of central authorities or the shape of cross section of interior silver layer in corresponding circular or rectangle.
The interior layers of copper of described circle or rectangular aluminum wire main body central authorities or the outer surface cloth of interior silver layer are provided with raised body.
The outer layers of copper of the outside wall surface of described aluminum steel main body and/or the outside wall surface of outer silver layer are provided with one deck silver layer, and described polyamidoimide or polyamide-imide insulating lacquer layer are located on this silver layer.
Described insulating barrier comprises the polyester-imide layer, organic coating and/or the polyamide imide that are coated with successively, also or comprise the polyamide imide, organic coating and/or the polyamide-imide insulating lacquer layer that are coated with successively.
Described polyamidoimide or polyamide-imide insulating lacquer layer are provided with one deck self-lubricating polyurethane insulating enamelled coating.
The utility model enamel insulated aluminium wire had both had good tin-welding, need not do special processing as aluminum steel; Maintain again the lightweight advantage of aluminum steel, very effective to the weight reducing winding or coil; The more important thing is the electrical property optimizing enamel insulated aluminium wire, same line cross-sectional area has more high load capability, and its enamelled coating has the resistance to temperature characterisitic of significant oil resistant, relatively power output is improve under square one, effectively reduce production cost, its corona-resistance property is better in addition, can extend the useful life of motor.
