Description
Technical field
The utility model relates to a kind of insulation copper flat wire wrapped.
Background technology
Along with national economy starves development, living standards of the people improve constantly, power load is corresponding increase also, motor, electrical equipment are towards future developments such as voltage levels, high power, Large Copacity, high-performance, impel electrical machine insulation to following several future development: (1) high thermal endurance class: the raising of the electric pressure of machine operation, the increase of capacity, make motor operationally liberated heat increase considerably, therefore must improve the normal use of the thermal endurance class guarantee motor of insulating material; (2) high-performance: comprise electric property, mechanical performance, chemical resistance, environment resistant etc.; (3) thinning insulation thickness: due to the increase of motor heat release, for ensureing the instructions for use of motor, must reduce electric machine temperature rise, therefore needs to reduce insulation thickness; (4) low cost: comprise the raw material using low cost, and the aspect such as the technology of low cost and quality control.
Motor is to the requirement of insulation property, higher requirement is proposed to the insulation property of lapped wire, and many glass fiber or the insulating varnish of generally adopting of lapped wire of the prior art, for meeting the requirement of product dielectric strength and other electrical characteristics, often because insulation thickness makes more greatly motor winding volume comparatively large, the requirement of miniaturized motor volume cannot be met.
Summary of the invention
The insulation copper flat wire wrapped that the utility model provides a kind of good insulation preformance, insulation thickness little.
The technical scheme of insulation copper flat wire wrapped provided by the utility model is: a kind of insulation copper flat wire wrapped, comprise conductor and be coated on the insulating barrier outside conductor, conductor is copper strap wire, the layer structure of described insulating barrier for being made up of the low resin mica tape layer arranged successively from inside to outside along copper strap wire radial direction, the first insulating barrier, double-deck alkali-free glass wool layer, the second insulating barrier.
Layer glass silk in described double-deck alkali-free glass wool layer is rightabout coiling.
The first described insulating barrier and the second insulating barrier are dipping enamelled coating.
The beneficial effects of the utility model are: the layer structure of insulating barrier for being made up of low resin mica tape layer, the first insulating barrier, double-deck alkali-free glass wool layer, the second insulating barrier of insulation copper flat wire wrapped provided by the utility model, wherein, the adhesive content of low resin mica tape layer is few, the chemical constitution of natural mica can be kept to greatest extent, dielectric strength is high, there is good corona-resistance property, and the air permeability of this low resin mica tape layer is high, good penetrability, high temperature resistant, radiation hardness, resistance to chemical attack.Employing double layer of insulation and the double glazing silk layer be folded between insulating barrier under the prerequisite of insulation property ensureing lapped wire, can effectively improve the intensity of lapped wire.
Further, the layer glass silk in two-layer alkali-free glass wool layer is rightabout coiling, improves the intensity of lapped wire like this, increases pliability, not easy to crack when coiling bends, and not easily disconnects during stretching.
Further, two insulating barriers are dipping enamelled coating, when the first insulating barrier carries out impregnation process, effectively can get rid of the air of mica tape stacked package gap part, mica belt and copper strap wire are closely affixed, guarantee the insulation effect to copper strap wire conductor.And the second insulating barrier is when carrying out impregnation process, the layer glass silk in double-deck alkali-free glass wool layer can be made closely to paste, in use there will not be delamination splitting phenomenon.Improve the insulation property of product, mechanical property and humidity resistance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of insulation copper flat wire wrapped provided by the utility model;
Fig. 2 is the cross section structure of copper strap wire shown in Fig. 1 schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2, a kind of embodiment of the copper flat wire wrapped that insulate, copper strap wire in this embodiment comprises conductor and insulating barrier, wherein, conductor is copper strap wire 1, the layer structure of insulating barrier for being made up of the low resin mica tape 2 layers arranged successively from inside to outside along copper strap wire radial direction, the first insulating barrier 3, double-deck alkali-free glass wool layer 4, second insulating barrier 5.
Wherein, the layer glass silk in double-deck alkali-free glass wool layer 4 is rightabout coiling, and the first insulating barrier 3 and the second insulating barrier 5 are dipping enamelled coating.
The copper flat wire wrapped provided in the present embodiment mainly uses low resin mica tape and glass fiber to carry out wrapped, wherein, low resin mica tape adhesive content is few, maintain the chemical constitution of natural mica to greatest extent, dielectric strength is high, has good corona-resistance property, and the air permeability of low resin mica tape is high, good penetrability, high temperature resistant, radiation hardness, resistance to chemical attack.During the first insulating barrier impregnation process, the air between low resin mica tape stacked package gap can be discharged, low resin mica tape and copper strap wire are closely affixed, guarantee the insulation effect to copper strap wire.And use the contrary coiling of double-deck alkali-free glass wool, and the intensity of lapped wire can be improved, increase pliability, not easy to crack when coiling bends, not easily disconnect during stretching wire.When second insulating barrier carries out impregnation process, the glass fiber in double-deck alkali-free glass wool layer can be made closely to paste, in use procedure, there will not be delamination splitting phenomenon.Thus improve the insulation property of product, mechanical property and humidity resistance.
In above-described embodiment, the layer glass silk coiling in the opposite direction in two-layer alkali-free glass wool layer, in other embodiments, also can adopt equidirectional coiling layer glass silk.
In above-described embodiment, dielectric layers is dipping enamelled coating, and in other embodiments, insulating barrier also can adopt insulating resin structure.
