Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Be a kind of 200 grades of Inverter fed motor enamelling cuprum round line disclosed by the utility model, including conducting wire 1 referring to Fig. 1, conducting wire 1 by Copper-tin alloy material is made.
The outer peripheral surface of conducting wire 1 is coated with insulating lacquer layer, and insulating lacquer layer successively includes inner insulating layer 2, interior resistance to electricity from inside to outside Dizzy insulating layer 3, outer corona-resistant insulation layer 5 and external insulation layer 6.Wherein inner insulating layer 2 is 180 grades of polyester-imide insulating layers, interior resistance to Corona insulating layer 3 is 180 grades of Inverter fed motor polyester-imide layers for being added to Alpha-alumina and gama-alumina, outer corona-resistant insulation layer 5 To be added to Nano-meter SiO_22200 grades of polyamide imides, external insulation layer 6 be 200 grades of polyamidoimide insulating layers.
By four layers of the coating for meeting insulating materials, so that the enamelling cuprum round line has very high insulation effect, and With excellent corona-resistance property.Wherein, the polyester-imide that Alpha-alumina and gama-alumina is added has conventional polyester imines number Corona-resistance property again is received and rice SiO is added2Polyamidoimide not only corona-resistance property with higher, also have longer Service life.
It pulls and is bent since in some cases, enamelling cuprum round line often will receive, and the insulating lacquer layer coated is in transition It may fall off after stretch bending deformation, the conducting wire 1 of enamelling cuprum round line is even broken, therefore is enhancing enamelling cuprum round line Mechanical property, is equipped with enhancement layer 4 between interior corona-resistant insulation layer 3 and outer corona-resistant insulation layer 55, and enhancement layer 4 includes close hands over For the tensile cord 41 and bending resistance line 42 of distribution.
Referring to Fig. 1 and 2, tensile cord 41 and the equal cross section of bending resistance line 42 are fan-shaped, and outer dimension is identical, and tension The internal diameter of line 41 and bending resistance line 42 is equal with the outer diameter of interior corona-resistant insulation layer 3, the outer diameter of tensile cord 41 and bending resistance line 42 and outer The internal diameter of corona-resistant insulation layer 5 is equal.
Wherein, tensile cord 41 includes inner core and protective layer 413, and wherein inner core includes and the glass fibers disposed in parallel of conducting wire 1 Silk 411 is tieed up, the tensile property of enamelling cuprum round line is improved by the glass fiber 411 of high-tensile, due to glass fiber 411 wearability itself are lower, Yi Fasheng wear and rupture, therefore inner core further includes the more outer peripheral surface spiral shells along glass fiber 411 The polyamide fibre auxiliary wire 412 of winding is revolved, more polyamide fibre auxiliary wires 412 are closely uniformly arranged, and pass through the polyamide fibre with preferable wearability Glass fiber 411 is protected, and is arranged by 412 spiral of polyamide fibre auxiliary wire, the bending resistance of inner core itself is reinforced.This Outside, protective layer 413 is made of aramid fiber material, is carried out further by having the aramid fiber material compared with high-flexural strength to tensile cord 41 Strengthen, enhances the bending resistance of tensile cord 41.
In addition, bending resistance line 42 is made of PAI plastic material, by the PAI plastics with higher comprehensive mechanical property, into one Step protects tensile cord 41, and further enhances the bending resistance of enamelling cuprum round line.
It is additionally provided with wearing layer 7 in the outer peripheral sidewall of external insulation layer 6, wearing layer 7 is made of nylon material.
It the implementation principle of the present embodiment and has the beneficial effect that
By the setting of four layers of insulating materials, insulation effect is improved, and wherein have the effect of Inverter fed motor two layers, greatly Ground improves the service life of the enamelling cuprum round line.For the tensile strength for enhancing the enamelling cuprum round line, in interior corona-resistant insulation layer 3 Enhancement layer 4 is equipped between outer corona-resistant insulation layer 5, by the glass fiber 411 of enhancement layer 4, so that tensile cord 41 has Very high intensity, but glass fiber 411 brittleness with higher itself easily occur abrasion and fracture, therefore are equipped with a plurality of use In the polyamide fibre auxiliary wire 412 of protection glass fiber 411, avoids glass fiber 411 to be worn destruction as far as possible, be arranged simultaneously Protective layer 413 makes tensile cord 41 also have excellent bending strength other than with good tensile strength.Enhancement layer 4 is arranged Bending resistance line 42 then further increase bending strength for enamelling cuprum round line, since bending resistance line 42 and tensile cord 41 are uniformly distributed, make Whole uniform force is obtained, and due to bending resistance line 42 and 41 tight distribution of tensile cord, it is possible to reduce generate because of the gap of enhancement layer 4 Bubble.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical Within novel protection scope.
