Abstract
The utility model relates to the metal conductor field, and specifically relates to a paper-wrapped film composite wire. The paper-wrapped film composite wire comprises a conductor provided with a film layer, the film layer is wrapped with an insulating paper layer, the film layer is prepared by corona resistant polyimide films, the width of the film layer is 14-18mm, and the thickness of the film layer is 0.02-0.03mm; and the film layer comprises an internal layer film and an external layer film, and the internal layer film is wrapped with the external layer film. The piece of insulating paper and the films are used for the paper-wrapped film composite wire, the two insulating layers are provided with higher withstand voltage grade and mechanical strength and the like, so that finished products produced by the paper-wrapped film composite wires are good in each performance index. The films are disposed inside the insulating layer, due to the fact that the films are relatively thin, if the films are positioned at the outer layer, the films are liable to be scratched or cut when winding a transformer, and major accidents and economic losses are easily caused.
Description
Technical field
The utility model relates to plain conductor field, is a kind of paper bag Film laminated line specifically.
Background technology
Paper covered wire is mainly used in oil-immersed type transformer.But for paper bag Film laminated copper flat wire wrapped, this winding wire requires to bear judder in some occasion and lower centrifugal force at a high speed, the tolerance corona under high voltage with puncture, the resistance to chemical attack under special atmosphere etc.
Also the improvement that has pair copper strap wire to carry out in existing patent, if application number is CN200320105347.X, application time is 2003-11-07, the utility model patent of " metal foil thin-membrane wire " by name, its patent scheme is: a kind of metal foil thin-membrane wire, have film, metal forming wire, skin sets gradually pressure-sensitive adhesive layer, film, interior pressure-sensitive adhesive layer, insulation enamelled coating, metal forming, film.Metal foil thin-membrane wire is double-deck, MULTILAYER COMPOSITE, for not wide, not equidistant, for symmetrical bilayer, multilayer and asymmetric bilayer, multi-layer compound structure, for shaped form is symmetrical double-deck, multilayer and asymmetric bilayer, multi-layer compound structure, metal foil thin-membrane wire is suitable for various electronically controlled holding wires and low pressure small-power power line, conductance is high, resistance is little, easy to install.
Above-mentioned patent is not also suitable for the production of the copper strap wire of film, because film is thinner, metal forming is sharper on the one hand, the great quality accident of easily scratching film, another aspect is because manufacturing procedure is loaded down with trivial details, and voltage withstand class is low, so this patented product is not suitable for manufacturing on a large scale.
Summary of the invention
The problems referred to above that exist in order to overcome existing plain conductor, now a kind of paper bag Film laminated line of special proposition.
Concrete scheme of the present utility model is as follows:
A paper bag Film laminated line, comprises conductor, it is characterized in that: described conductor is provided with thin layer, at described film, is surrounded with insulating paper layer outward, and described thin layer is corona-resistant polyimide film, and described thin layer width is 14-18mm; Thickness is 0.02-0.03mm; Described thin layer comprises internal layer membrane and outer membrane, and outer membrane is wrapped on internal layer membrane.
Described internal layer membrane is that gap is wrapped, and gap width is not more than 2mm, the outer layer insulation paper lap wound bag of attaching most importance to, and overlapping width is not less than 2mm.
Described insulating paper is 500kV turn-to-turn insulation paper, and the bilateral thickness of internal layer membrane and outer membrane is 0.05mm, and the maximum bilateral thickness of insulating paper is 0.30mm, and total insulation is 0.40mm to the maximum.
Described conductor is copper strap wire.
Described corona-resistant polyimide film hot strength is longitudinally 180-190Mpa, is laterally 160-170Mpa; Elongation at break is longitudinally 65-68%, is laterally 73-77%; Power frequency electrical strength is 270-290Mv/m.
In the time of in 200 ℃ of situations, surface resistivity is 3.1*10
13, specific volume resistance is 2.4*10
11.At 90 ℃, peak value is 1kV, and frequency is 20kHz, in the situation that the wavefront time is 400ns, is greater than 8h the useful life of resistance to corona.
The utility model has the advantage of:
What 1, this patent invention was used is insulating paper and film, and two kinds of insulating barriers can have higher voltage withstand class and mechanical strength etc., and the finished product indices performance that can make the present invention produce is better.The utility model film is in insulating barrier, because film is thinner, if film, in outer field words, when coiling transformer, easily scratches or scratch film, easily causes a serious accident and economic loss.
2, paper bag Film laminated lapped wire of the present utility model fuses into one film and paper-covered copper flat wire, and temperature resistant grade is high, proof voltage grade is high and mechanical performance is strong.On the basis of common paper envelope curve, increase film, increased corona-resistance property, improved dielectric strength, electrical strength simultaneously.
