Abstract

The utility model discloses a kind of transformer foil around copper bar, comprise the paper tinsel that connects as one successively around section, bending section and draw section, described paper tinsel is provided with gradient along its length around section.Improve stock utilization, easily realize batch production, simultaneously also because the paper tinsel of copper bar has been provided with gradient around section, heat radiation can have been accelerated in oblique, prevent thermal breakdown, also ensure that the quality of product at the cost reducing product simultaneously.

Description

A kind of transformer foil is around copper bar
Technical field
The utility model relates to the field transformer of power equipment, refers to that a kind of transformer foil is around copper bar especially.
Background technology
According to the requirement of country to energy-saving consumption-reducing, transformer producer also all energy-conservation for developing, the transformer of nodal wood type and make great efforts research.How particularly time copper resource scarcity recently, save the copper material making transformer used and more seem particularly important.Because past paper tinsel is around employing monoblock copper bar, stock utilization is not high, and cost is high, causes very large waste, is unfavorable for that the long-run development of sustainability of natural resources requires and produces in batches.
China's Authorization Notice No. is that the patent of CN201489968U discloses a kind of foil winding type coil leading copper busbar, and the welding portion width of copper bar differs, by reducing the effect reaching saving copper amount of the welding portion of part.In addition, Chinese Authorization Notice No. is that the patent of CN101383219B discloses a kind of paper tinsel coiling copper bar, according to the size of Copper Foil current-carrying, determines the length dimension of copper bar, reaches the object of saving material with this.Though copper bar disclosed above saves material, manufacture more complicated, and the effect of saving material is obvious not.
Therefore, be necessary to provide a kind of new transformer foil around copper bar, to solve the problems of the technologies described above.
Summary of the invention
The utility model object is to provide a kind of transformer foil around copper bar, and stock utilization is high, easily produces in batches.
The technical solution of the utility model is achieved in that a kind of transformer foil is around copper bar, and comprise the paper tinsel that connects as one successively around section, bending section and draw section, described paper tinsel is provided with gradient along its length around section.
In technique scheme, the part of described paper tinsel in section is that chamfer is trapezoidal.
In technique scheme, described paper tinsel another part in section is rectangle and described chamfer is trapezoidal is interconnected.
The utility model is compared with prior art: by being provided with the paper tinsel that connects as one at transformer foil around section, bending section and draw section on copper bar, improve stock utilization, easy realization batch production, simultaneously also because the paper tinsel of copper bar has been provided with gradient around section, heat radiation can be accelerated in oblique, prevent thermal breakdown, also ensure that the quality of product at the cost reducing product simultaneously.
Accompanying drawing explanation
Fig. 1 is that the utility model transformer foil is around copper bar figure;
Fig. 2 is copper bar end view;
Fig. 3 is the utility model copper bar machining sketch chart.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 1 and 2, a kind of transformer foil is around copper bar, and it comprises the paper tinsel that connects as one successively around section 1, bending section 2 and draw section 3, and described paper tinsel is provided with gradient along its length around section 1.The part of described paper tinsel in section is that chamfer is trapezoidal.Described paper tinsel another part in section is rectangle and described chamfer is trapezoidal is interconnected.
As shown in Figure 3, adopt above-mentioned novel copper bar can after the copper bar of same monoblock is directly cut sth. askew and cut, be divided into two pieces of bendings formed form described copper bar respectively paper tinsel around section 1, bending section 2 and draw section 3.So, technique is simple, improves stock utilization, easily realizes batch production, simultaneously also because the paper tinsel of copper bar has been provided with gradient around section, can have accelerated heat radiation, prevent thermal breakdown, also ensure that the quality of product at the cost reducing product simultaneously in oblique.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
