Among the figure: 1, justify bare copper wire; 2, polyesterimide enamelled wire enamelled coating; 3, polyamide-imide enamelled wire varnishes layer; 4, double glazing fiber layer; 5, insulating varnish coating.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection range of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
Shown in accompanying drawing 1, the double glass fiber of anti-cold-producing medium bag enamelling cuprum round line in the present embodiment, comprise round bare copper wire 1 and the insulating barrier that is coated on round bare copper wire 1 periphery, insulating barrier comprises polyesterimide enamelled wire enamelled coating 2, polyamide-imide enamelled wire varnishes layer 3, double glazing fiber layer 4 and the insulating varnish coating 5 that sets gradually from the inside to surface.
The presentation quality of circle bare copper wire 1 should clean, smooth, the burr that do not have, scratch, copper powder, oxide layer and greasy dirt, no bubble, and color and luster is even, does not have the sensation of gluing hand; Requirement to the resistivity of circle bare copper wire 1 material is, adopt precision type bridge, test fixture, pocket knife, undertaken by GB3048.2 metallic conductor resistivity test method, the precision of measuring allows to be not less than 0.5%. resistivity and should meet among the GB7672 the 8.1st regulation method and measure and calculate, that is: R
20=ρ
20/ S

2 max
ρ
20: the resistivity of conductor in the time of 20 ℃, Ω .mm
2/ m
When the dc resistance of conductor meets the GB7672 regulation, the diameter that allows conductor is less than 1.3% of this conductor nominal value lower deviation, definition maximum outside diameter: on two positions of 1000mm, each position is measured along equally distributed three places of sample circumference, and the maximum that (measuring altogether six times) measures is maximum outside diameter; Conductor diameter: on two positions of 1000mm, in each position, equally distributed three places are measured along the sample circumference with the outer field insulating barrier of alcolhol burner burning-off (behind the burning-off insulation enamelled coating, removing the glass fibre lapping layer with the method for not damaging conductor).Insulation thickness: the mean value that deducts conductor diameter with the mean value of maximum outside diameter is insulation thickness.Winding wire in this standard nominal value range, the film thickness of its composite enameled wire should meet the regulation among the GB6109, and the wrapped thickness of glass fiber is 0.25mm.Consider that glass fiber yarn joint can occur in wrapped process, therefore allow the winding wire part overproof, but overproof thickness should be controlled in the scope of total insulation thickness 20%, length should not surpass 300mm.For example: the glass fiber covered wire of Φ 1.50, maximum outside diameter: conductor diameter+insulation thickness+conductor and the insulation thickness upper deviation=1.856.
The polyesterimide wire enamel model of using in the polyesterimide enamelled wire enamelled coating 2 is 1753-34L, is 180 grades (the minimum temperature index is 180, and caloric impact temperature is at least 200 ℃), and minimum solids content is 34% polyesterimide wire enamel.In softening breakdown test, under 300 ℃ of temperature, can not be breakdown in 2 minutes, 1753-34L type polyesterimide wire enamel has high thermal shock resistance properties.
The model of the polyamide-imide enamelled wire varnishes that uses in the polyamide-imide enamelled wire varnishes layer 3 is 1766-25, is 200 grades (the minimum temperature index is 200, and caloric impact temperature is at least 220 ℃), and minimum solids content is 25% polyamide-imide enamelled wire varnishes.In the test of anti-refrigerant, the percentage of extract is no more than 0.5%, and minimum break-down voltage is 75% of a setting, in softening breakdown test, and under 320 ℃ of temperature, can not be breakdown in 2 minutes; 1766-25 type polyamide-imide enamelled wire varnishes has good anti-refrigerant performance.
Double glazing fiber layer 4 comprises the layer glass silvalin, and the thickness of the double glazing fiber layer in the present embodiment is 0.25mm, and the layer glass silvalin is wrapped on the polyamide-imide enamelled wire varnishes layer 3 along helical form with opposite direction.When changing glass fibre in the wrapped process, allow the thickness of this place's insulation can surpass 20% of regulation insulation gross thickness, but the length at this place should be controlled in the 200mm.
After having twined glass fibre layer 4, on glass fiber yarn 4, smear insulating varnish coating 5, present embodiment adopt can be stable be present in D073 freon resistant insulating impregnating varnish in cold-producing medium and the refrigerator oil as the material of insulating varnish coating 5.
In the end can also carry out the multinomial performance test to final products, for example can adopt crooked method examination pliability, after the test, outer field double glass fiber lapping layer does not ftracture to the compound inslation lacquer coat that exposes internal layer; Adopt pulling method test tack, specimen preparation is for being cut to the coat of paint of enamelled wire on every side with the pocket knife edge, get the long sample of 300mm, (outer field lapping layer is along the circumferential direction removed with pocket knife in the two ends in the trial zone as the tension test district to reserve one section of 100mm, but can not cut to conductor, respectively do a ring-shaped mark then), end with sample is fixed in the anchor clamps then, under the straightened condition that guarantees sample, the other end of sample is fixed on the other end anchor clamps, and firing test equipment is with the draw speed tensile sample elongation 15% of 300 ± mm/min, behind the specimen test, should not have serious cracking or peel off phenomenon; And for example adopt steel ball method test puncture voltage, the diameter of reeling when the diameter of winding wire conductor is less than or equal to 1.50mm is 8mm., the winding diameter of diameter during greater than 1.50mm or less than 2.00mm is 10mm., four sample puncture voltages are not less than 1800 volts, allow one of them sample to be not less than or equal 1200 volts.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
