Abstract
The utility model discloses a composite film-wrapped flat aluminum wire, the cross section of which is flat in shape. The composite film-wrapped flat aluminum wire comprises an internal conductor and an insulating layer combined to the outer surface of the internal conductor. The insulating layer is a polyimide-fluorine 46 composite film. The inner conductor is a flat aluminum wire body with high width-to-thickness ratio. Compared with the prior art, the composite film-wrapped flat aluminum wire meets the requirement that a transformer and a traction motor should resist the voltage higher than 2000 V under the condition of intense bending of windings, thereby being applicable to transformer and traction motor windings.
Description
Technical field
The utility model relates to power domain, exactly refers to the wrapped flat aluminium wire of a kind of laminated film.
Background technology
Film wrapped wire is an important kind of winding wire, is made up of conductor and thin dielectric film two parts, and bare wire, after annealing softening, then through repeatedly wrapped, cures and forms.Meet standard-required but produce, meet again the product of customer requirement and be not easy, it is subject to raw material quality, technological parameter, production equipment, the factor impacts such as environment, therefore, the mass property of various lapped wires is different, but all possesses mechanical performance, chemical property, electrical insulation properties, the large performance of hot property four.
Can divide by the purposes of lapped wire:
1, general purpose enamelled wire (ordinary lines) is mainly used in general motor, electrical equipment, instrument.The winding wire of the workplaces such as transformer, as: paper covered wire, silk-covered wire, enamel-cover composite filament hold envelope curve etc.
2, heat-resisting lapped wire; Be mainly used in the motor of 180 DEG C and above temperature environment work, electrical equipment, instrument, the winding wire of the workplaces such as transformer, as: film holds envelope curve etc.
3, the lapped wire of special purpose; Refer to and there is the enamelled wire that certain mass property requires, for the winding wire of specific occasion, as: film bag sintering line etc.
Divide by conductor material: copper cash, aluminum steel, alloy wire.
Divide by material shape: circle line, lenticular wire, tubular wire.
Divide by insulating material: paper bag lapped wire, silk hold that envelope curve, enamel-cover composite filament hold envelope curve, film holds envelope curve, terylene compound glass silk bag sintering line, terylene compound glass silk bag enamel-cover sintering line, film bag sintering line etc.
Because a lot of transformers and traction electric machine need very large electric current, therefore need winding wire size super large, large flakiness ratio and insulating barrier to keep more than 2000 volts withstand voltage properties under winding wire bends condition, and existing product is difficult to meet.
Utility model content
For above-mentioned defect, the technical problem that the utility model solves is to provide a kind of laminated film wrapped flat aluminium wire, meet the more than 2000 volts requirement of proof voltage under winding bends condition of transformer and traction electric machine, can be applied to transformer and traction electric machine winding.
In order to solve above technical problem, the wrapped flat aluminium wire of laminated film that the utility model provides, the cross section of the wrapped flat aluminium wire of described laminated film is a flat pattern, comprise inner conductor and the insulating barrier that is compound in inner conductor outer surface, described insulating barrier is polyimide-fluorine 46 laminated films, the flat aluminium wire that described inner conductor is large flakiness ratio.
Preferably, described insulating barrier is the composite insulation layer with tack coat.
Preferably, the length of described inner conductor and wide ratio are greater than 4.
The wrapped flat aluminium wire of laminated film that the utility model provides, the cross section of the wrapped flat aluminium wire of described laminated film is a flat pattern, comprise inner conductor and the insulating barrier that is compound in inner conductor outer surface, described insulating barrier is polyimide-fluorine 46 laminated films, the flat aluminium wire that described inner conductor is large flakiness ratio.Compared with prior art, the wrapped flat aluminium wire of laminated film that the utility model provides, meet the more than 2000 volts requirement of proof voltage under winding bends condition of transformer and traction electric machine, inner conductor has large flakiness ratio, has the polyimide-fluorine 46 laminated film insulating barriers of tack coat, can be applied to transformer and traction electric machine winding.
