Abstract
The utility model discloses a glass fiber wrapped enameled copper flat wire. The glass fiber wrapped enameled copper flat wire comprises a copper flat wire inner layer, an insulating resin paint layer and a glass fiber wrapping layer; the copper flat wire inner is adopted as an inner core; the outer side of the copper flat wire inner layer is coated with the insulating resin paint layer; and the outer layer of the insulating resin paint layer is provided with the glass fiber wrapping layer. The glass fiber wrapped enameled copper flat wire of the utility model not only has the advantages of various kinds of original transformer coils, but also is advantageous in strong heat resistance and long service life; and further, coarse-pitch wrapping is adopted, and therefore, bending-caused cracking of a winding wire when a coil is wound can be avoided, and it can be ensured that the insulating resin paint layer is tightly bonded on the copper flat wire, and thus, the service life of the copper flat wire can be prolonged, and performance indexes such as bending performance and adhesion performance can be improved.
Description
Technical field
The utility model relates to a kind of glass fiber bag enameling copper strap wire, specifically, particularly relates to a kind of glass fiber bag enameling copper strap wire that is suitable for the winding of doing big-and-middle-sized high-voltage motor, electrical equipment.
Background technology
Along with developing rapidly of transformer industry, especially the competition of dry-type transformer industry is very fierce, the production firm of some dry-type transformers begins to research and develop low-cost coil, way is: wrapped glass fiber covering outside conductor, so that it has the good insulation performance performance, but in its course of work, can produce a large amount of heats, if silk copper-clad lenticular wire does not have good heat-resistant, then be easy to after using several times, just be damaged, its useful life is shorter.
In addition, at present, used winding wire generally adopts wrapped double glazing silk on copper strap wire or the mica tape copper-clad lenticular wire, and scribbles one deck bonding lacquer with the surface between each layer, to solve insulation.
It is 1-2 ° of wrapping angle that but the double glazing silk of these structures all adopts fine pith, when coiling, bending and the adhesion property of winding wire do not reach requirement, in use easily produce the insulating barrier cracking on the flexure plane of winding coil, and its coil is destroyed and reduction of service life.
The utility model content
The purpose of this utility model is to provide a kind of glass fiber bag enameling copper strap wire, with improve heat resistance, improve crooked, adhere to index, can satisfy instructions for use, increase the service life, thereby overcome deficiency in the conventional art, realize the purpose of this utility model.
The technical problem that the utility model solves can realize by the following technical solutions:
Glass fiber bag enameling copper strap wire, it comprises copper strap wire internal layer, insulating resin enamelled coating and glass fiber covering; Described copper strap wire internal layer is made as inner core, and the outside of copper strap wire internal layer scribbles the insulating resin enamelled coating, and the skin of described insulating resin enamelled coating is provided with the glass fiber covering.
In an embodiment of the present utility model, the thickness of described insulating resin enamelled coating is the 0.3-0.5 millimeter.
In an embodiment of the present utility model, the cross section of described copper strap wire internal layer is rectangle.
In an embodiment of the present utility model, described glass fiber covering adopts the netted glass fiber layer of 5.3 millimeters lay of lapping, 20 degree wrapping angles.
The beneficial effects of the utility model are: both kept the advantage of original range transformer coil, had the high advantage of thermal endurance again, high life.In addition, adopted wrapped coarse pitch, winding wire bending crack phenomenon when having avoided coiling can guarantee that the insulating resin enamelled coating is close on the copper strap wire, therefore increases the service life, and improves performance index such as bending, tack.
Description of drawings
Fig. 1 is the structural representation of glass fiber bag enameling copper strap wire described in the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1, glass fiber bag enameling copper strap wire described in the utility model, it mainly comprises copper strap wire internal layer 100, insulating resin enamelled coating 200 and the glass fiber covering 300 that sets gradually from inside to outside.
Wherein, copper strap wire internal layer 100 is made as inner core, and the cross section of copper strap wire internal layer 100 is rectangle, by this structural design, has improved copper strap wire crooked position adhesive force.
Scribble one deck insulating resin lacquer in the outside of copper strap wire internal layer 100 as insulating resin enamelled coating 200, the thickness range of insulating resin enamelled coating 200 can be selected suitable numerical value according to concrete demand in actual production within the 0.3-0.5 millimeter.
Skin at insulating resin enamelled coating 200 is provided with glass fiber covering 300, glass fiber covering 300 adopts the netted glass fiber layer of 5.3 millimeters lay of lapping, 20 degree wrapping angles, adopt the wrapping angle of coarse pitch, when coiling, bending and the adhesion property of winding wire reach requirement, in use be difficult on the flexure plane of winding coil producing the insulating barrier cracking, prolonged useful life.
The utility model had both kept the advantage of original range transformer coil, had the high advantage of thermal endurance again, high life.In addition, adopted wrapped coarse pitch, winding wire bending crack phenomenon when having avoided coiling can guarantee that the insulating resin enamelled coating is close on the copper strap wire, therefore increases the service life, and improves performance index such as bending, tack.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
