Abstract
The utility model relates to an iron core structure of a transformer, which comprises an iron yoke and iron core columns, wherein the cross sections of the iron core columns are in elliptical shapes, and the cross section shapes of the iron yoke and the iron core columns are unequal. The iron core structure of a transformer, which adopts the elliptical cross section, can shorten the distance between the iron core columns of the iron core structure of the transformer on the premise of ensuring the unchanged effective cross section of the iron core structure, and the unequal cross sections of the iron core columns and the iron yoke are convenient for flexibly adjusting the no-load loss parameter of the transformer, thereby reducing the manufacture cost of the transformer, saving raw materials, being convenient for clamping and clamping the iron core structure without changing a clamping way in the traditional structure.
Description
(1) technical field
The utility model relates to a kind of transformer, relates in particular to a kind of core structure of transformer.
(2) background technology
Existing oil immersion-type distribution transformer generally adopts post, the prismatic core structure of yoke, and adopts the computer optimization designing technique to carry out the material-saving design.The core structure of transformer is made up of iron yoke and iron core column, and is formed by the very thin silicon steel sheet stack of slices, and the cross section of the core structure of transformer can be made different geometries.As positive circle, Long Circle, rectangle or the like.Different geometric influence is to the profile of transformer, the feasibility of the cost of raw material and technology.As the core structure of Long Circle cross section difficulty relatively when the mounting coil, coil winds the back easy deformation.The winding that core structure disposed of rectangular cross section because the radius of curvature at 4 angles is little, easily causes electromagnetic wire outer surface insulating barrier cracking when coiling, influence workmanship.
(3) summary of the invention
In order to overcome deficiency above-mentioned in the prior art, the utility model provides a kind of core structure of transformer, and the core structure of this transformer can be avoided above manufacturing defect, and can reduce the manufacturing cost and the power consumption of transformer, enlarges its scope of application.
The technical scheme in the invention for solving the technical problem is: a kind of core structure of transformer, to form by iron yoke and iron core column, and the shape of cross section of described iron core column is oval.
As further improvement of the utility model, the shape of cross section of described iron yoke and described iron core column does not wait.
The beneficial effects of the utility model are: thus because the shape of cross section of iron core column is the oval length that has shortened the iron yoke, makes silicon steel sheet reduce consumption, thereby reduced no-load loss.Satisfying under the prerequisite of national standard, the core structure of oval cross section than the close height of the magnetic of the core structure of positive circular cross section a bit.The close height of magnetic a bit means that just wire turn can lack, thereby has saved the consumption of electromagnetic wire.Consume because of silicon steel sheet, electromagnetic wire again and lacked, thereby the shell of transformer is diminished a bit.Shell is a little bit smaller, thereby has reduced the consumption of transformer oil.Finally reach the effect that total cost significantly descends.
Adopt the transformer fe cored structure of oval cross section, can be under the constant prerequisite in the effective cross section that guarantees core structure, shorten the distance between the transformer core structural iron stem, thereby reduced the manufacturing cost of transformer, raw material have been saved, and clamp conveniently, can on existing structure, not change clamping mode and clamp core construction.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cross sectional representation of the utility model core limb.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
According to the core structure of a kind of transformer illustrated in figures 1 and 2, to form by iron yoke 1 and iron core column 2, the shape of cross section of described iron core column 2 is oval.
Because thereby the shape of cross section of core limb 2 makes silicon steel sheet reduce consumption, thereby has reduced no-load loss for the oval length that has shortened iron yoke 1.Satisfying under the prerequisite of national standard, the core structure of oval cross section than the close height of the magnetic of the core structure of positive circular cross section a bit.The close height of magnetic a bit means that just wire turn can lack, thereby has saved the consumption of electromagnetic wire.Consume because of silicon steel sheet, electromagnetic wire again and lacked, thereby the shell of transformer is diminished a bit.Shell is a little bit smaller, thereby has reduced the consumption of transformer oil.Finally reach the effect that total cost significantly descends.
Adopt the transformer fe cored structure of oval cross section, can be under the constant prerequisite in the effective cross section that guarantees core structure, shorten the distance between the transformer core structural iron stem stem 2, thereby reduced the manufacturing cost of transformer, raw material have been saved, and clamp conveniently, can on existing structure, not change clamping mode and clamp core structure.
