Abstract
The utility model discloses a paper-covered copper flat wire. A copper conductor is arranged on the inner layer of the paper-covered copper flat wire, a piece of insulating paper is wrapped on the outer layer of the paper-covered copper flat wire, and the copper conductor is flat. By using the principle of skin effect, on one hand, copper is adopted as the conductor, and on the other hand, the surface area of the conductor is increased by flattening copper, the current-carrying capacity of the conductor is further increased, and the flat copper conductor is applied to certain fields for replacing the circular copper conductor with the same current-carrying capacity as the flat copper conductor, so that the cost of raw material is greatly reduced, and resources are saved.
Description
Technical field
The utility model relates to a kind of electromagnetism winding wire, particularly a kind of paper bag copper strap wire.
Background technology
China is a populous nation, and per capita resources is in status after relatively leaning on compared to other countries.And China is in a large-scaled construction period at present, and various resource consumptions are huge, and this development model is not approved more and more that country is also making great efforts to advocate and building a conservation-minded society.Copper is a kind of non-ferrous metal that plays extremely important effect in the modern industry, and it is widely used in industrial every field, but the copper ore resource of China is not abundant, and copper valency in the world is also high at present, has seriously restricted China's development of economic construction.
Therefore, take the corresponding techniques means to improve the utilization ratio of copper, economize on resources to greatest extent, reducing cost becomes a problem that is worth us to pay attention to.
Summary of the invention
The purpose of this utility model just is to provide a kind of paper bag copper strap wire, is applied in the winding coil of some electrical equipments to be issued in the situation of not sacrificing electric property and to reduce cost aim of saving to use flat type copper wire to substitute circular copper wire.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of paper bag copper strap wire, its internal layer are copper conductor, and the copper layer is coated with insulating paper, and described copper conductor is a flat.
Described insulating paper is coated on the copper conductor by wrapped mode.
Kelvin effect when know-why of the present utility model is the conductor flow overcurrent: when alternating current passes through conductor, electric current will be tending towards conductive surface and flow through.Consider this principle, it is long-pending that we improve surface of conductors by the mode that copper is flattened, thereby increase the ampacity of conductor.
The utility model adopts the advantage of technique scheme to be to improve the ampacity of copper conductor, can substitute the application of the round copper conductor of identical ampacity in some field, greatly reduces raw-material cost, has alleviated the weight of product, has saved resource.
Description of drawings
Fig. 1 is the structural representation of paper bag copper strap wire of the present 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 concrete accompanying drawing, further set forth the utility model.
A kind of paper bag copper strap wire as shown in Figure 1, its internal layer is a copper conductor 1, and copper conductor 1 is coated with insulating paper 2, and described copper conductor 1 is a flat.
Described insulating paper 2 is coated on the copper conductor by wrapped mode.
The broadside of the cross section of described copper conductor 1 is 2～16mm, and narrow limit is 0.8～5.6mm.
More than show and described basic principle of the present utility model, 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 the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, 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.
