Abstract
The utility model discloses an acetal enamelled wire. The wire comprises a metal wire core made of aluminium alloy material or rare earth high-ferro aluminium alloy material. The metal wire core is coated by a braid layer in the shape of a web braided by carbon fiber filaments. A bonding layer is arranged outside the braid layer and is wrapped by an insulating coating produced by acetal material. The adhesive force between the insulating coating and the metal wire core is strong, and thus the insulating coating does not fall off easily. Besides, the wire is good in warp resistance and not easy to break, and thus is good in usage performance. The acetal material has excellent resistance to thermal shock and scratching and good resistance to hydrolysis. The wire with a low production cost and good performance can be used for coils of windings of small-, medium- or mini-size motors, coils of oil-immersed transformers, and coils for electrical instruments, and thus has a good application prospect and value for promotion.
Description
technical field:
The utility model relates to the coil of general middle small machine, electrical micro-machine winding and oil-immersed type transformer, the enamelled wire of electric meter coil, relates in particular to a kind of acetal paint envelope curve.
background technology:
At present, enamelled wire has been widely applied to every field, also more and more higher for the requirement of enamelled wire, and common enamelled wire can not meet the demand in market.In the production field of enamelled wire, the metal core that great majority use is to be made up of copper product or copper aluminum composite material, because copper surface very easily forms oxidation spots, catalysis coat of paint aging, and copper aluminum composite material, its complex manufacturing process, production cycle is long, cost is high, the rich aluminium phenomenon aggravation of the poor copper in the simultaneous whole world, and developing a kind of material that can instead of copper has been the task of top priority.
In addition, the adhesive force between insulation enamelled coating and the metal core of enamelled wire is poor, easily comes off, and the anti-twist of enamelled wire lacks in ability simultaneously, the problems such as frangibility.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of acetal paint envelope curve, structural design novelty, realize with aluminium for copper, function admirable, can be used for the coil of middle small machine, electrical micro-machine winding and oil-immersed type transformer, the enamelled wire of coil for electric meter, insulation enamelled coating difficult drop-off, warp resistance performance improves.
The technical solution of the utility model is as follows:
Acetal paint envelope curve, it is characterized in that: comprise the metal core that aluminum alloy materials or rare earth high-iron aluminum alloy materials are made, metal core is coated with carbon fiber wire and is woven into the braid of netted formation, and braid is provided with adhering layer outward, and adhering layer is coated with the insulation enamelled coating that acetal material is made.
Described acetal paint envelope curve, is characterized in that: described metal core is circle line, lenticular wire.
Described acetal paint envelope curve, is characterized in that: described metal core when the lenticular wire, narrow limit is 0.80mm ~ 5.60mm, broadside is 2.00mm ~ 16.00mm.
Described acetal paint envelope curve, is characterized in that: the tensile strength>=90MPa of described metal core, elongation at break>=10%, specific insulation≤0.028264 Ω mm
2/ m.
The utility model has the advantages that:
1, the strong adhesion between the utility model insulation enamelled coating and metal core, insulation enamelled coating difficult drop-off, in addition, has good warp resistance performance, not frangibility, serviceability is good;
2, the thermal shock of the utility model acetal material is excellent, and scratch resistance is excellent, and anti-hydrolytic performance is good;
3, low cost of manufacture of the present utility model, function admirable, can be used for the coil of middle small machine, electrical micro-machine winding and oil-immersed type transformer, and electric meter coil, has good application prospect and promotional value.
accompanying drawing explanation:
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
embodiment:
Referring to Fig. 1, acetal paint envelope curve, comprise that aluminum alloy materials or rare earth high-iron aluminum alloy materials are made, cross section is circular metal core 1, metal core 1 is coated with carbon fiber wire and is woven into the braid 2 of netted formation, braid 2 is outer is provided with adhering layer 3, and adhering layer 3 is coated with the insulation enamelled coating 4 that acetal material is made.
Adhering layer 3 combines together with braid 2, the outer wall phase adhesion of the one side of adhering layer and metal linear 1, and another side and the enamelled coating 4 phase adhesions of insulating, improved adhesive force.
Tensile strength>=the 90MPa of metal core 1, elongation at break>=10%, specific insulation≤0.028264 Ω 0.028264 Ω mm
2/ m.
Insulation enamelled coating 4 is the thick acetals insulation of 120 grades of spies paint films, and paint film stands the stress of reeling, easily crack (before dipping must about 120 ℃ heat 1h more than, to eliminate stress).
Referring to Fig. 2, acetal paint envelope curve, comprise aluminum alloy materials or rare earth high-iron aluminum alloy materials metal core 1 that make, that cross section is flat, metal core 1 is coated with carbon fiber wire and is woven into the braid 2 of netted formation, braid is provided with adhering layer 3 outward, and adhering layer 3 is coated with the insulation enamelled coating 4 that acetal material is made.
Adhering layer 3 combines together with braid 2, the outer wall phase adhesion of the one side of adhering layer and metal linear 1, and another side and the enamelled coating 4 phase adhesions of insulating, improved adhesive force.
Tensile strength>=the 90MPa of metal core 1, elongation at break>=10%, specific insulation≤0.028264 Ω mm
2/ m.
Insulation enamelled coating 4 is 130 grades of thin acetal insulation paint films.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to spirit of the present utility model in the situation that, the utility model can be done any type of modification.
