Technical field
The utility model relates to PET polyester film insulating varnish pack transposition conducting wire for a kind of transformer, and PET polyester film insulating varnish pack transposition conducting wire is used for making Transformer Winding, belongs to Transformer Winding lead technology field.
Background technology
PET polyester film is called for short PET film, is to take PETG as raw material, adopts extrusion molding to make sheet, then the thin-film material of making through biaxial tension; High performance PE T polyester film insulating varnish pack transposition conducting wire is to take high-yield strength enameled transposition conductor as basis, outsourcing PET polyester film forms, at present, in electromagnetic wire industry, mostly PET polyester film insulating varnish pack transposition conducting wire is that common transposition core outsourcing PET polyester film forms, in process of production because PET polyester film has adsorptivity, in production process, easily adsorb impurity, affect properties of product.Because Transformer Winding coil moves in non-oil immersion environment, common production environment can not guarantee explosion-proof and the insulating properties that electromagnetic wire is good, common transposition core can not guarantee the Short Circuit withstand impact capacity of coil, resistivity has just determined the operating thermal losses of coil, and the size of percentage elongation has determined the winding process of coil simultaneously; Paint film insulation property have determined between coil thigh, the insulation effect of turn-to-turn and the possibility being short-circuited.Requirement to PET polyester film insulating varnish pack transposition conducting wire performance is also more and more higher, and the PET polyester film insulating varnish pack transposition conducting wire that background technology is produced can not meet the requirement of Transformer Winding.
Utility model content
The utility model object is to provide PET polyester film insulating varnish pack transposition conducting wire for a kind of transformer, guarantee that internal gas is moistening, clean, not contaminated, prevent PET polyester film absorption micronic dust, guarantee between transformer coil thigh, turn-to-turn has good insulation effect, be not short-circuited, solve the problem existing in background technology.
The technical solution of the utility model is:
PET polyester film insulating varnish pack transposition conducting wire for a kind of transformer, comprise high-yield strength low resistivity conductor, high withstand voltage paint film and high-cleanness PET polyester film, on the cross section of transposed conductor, have seven high-yield strength low resistivity conductor, every high-yield strength low resistivity conductor outside all scribbles high withstand voltage paint film; Three wire stacked are one group of wire, and two groups of arrangements of conductors are arranged, a high-yield strength low resistivity conductor is set above two groups of wires, and seven high-yield strength low resistivity conductor form conductor bundle; The outside of conductor bundle is surrounded by high-cleanness PET polyester film.
High-yield strength low resistivity conductor is used the method for the first rear drawing of extruding to produce, the stress R of high-yield strength low resistivity conductor when plastic elongation rate is 0.2%
p0.2reach 240-260Mpa, and resistivity is less than 0.017241 Ω mm
2/ m, percentage elongation is greater than 18%, and high-yield strength has improved the Short Circuit withstand impact capacity of coil greatly, and low-resistivity has reduced the operating thermal losses of coil, and meanwhile, percentage elongation is greater than 18% winding process that has guaranteed coil.
Described two groups of arrangements of conductors are arranged, between two groups of wires, are provided with self-adhesion enamelled coating, and two groups of wires are bonded together.
High-yield strength low resistivity conductor enters confined space, and this confined space keeps barotropic state, is provided with antistatic facility, and internal gas is moistening, clean, not contaminated, carries out transposed conductor production.
The beneficial effects of the utility model are: the utility model prevents PET polyester film absorption micronic dust, guarantee PET polyester film high-cleanness, because transformer coil moves in non-oil immersion environment, clean production environment has guaranteed that electromagnetic wire has good explosion-proof and insulating properties; More than paint film proof voltage ability reaches 5000v, and stable performance, high and stable paint film insulation property, have guaranteed between coil thigh, turn-to-turn has good insulation effect, are not short-circuited.
Accompanying drawing explanation
Fig. 1 is the utility model product cross section schematic diagram;
In figure: 1, high-yield strength low resistivity conductor; 2, high withstand voltage paint film; 3, high-cleanness PET polyester film; 4, self-adhesion enamelled coating.
