Abstract
An iron core structure of a dry type transformer comprises an iron core column and a yoke. Cross sections of the iron core column and the yoke are both oval. With the structure, both of the cross sections of the iron core column and the yoke are oval, thereby shortening length of the yoke, reducing consumption of silicon steel sheets, and lowering no-load loss. On the premise of meeting national standards, flux density of the iron core with the oval cross section is higher than that of an iron core with circular cross section so that wire turns of the iron core with the oval cross section can be fewer, thereby further saving usage of electric magnetic wires.
Description
(1) technical field
The utility model relates to a kind of dry-type transformer, relates in particular to a kind of core structure of dry-type 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 some iron yoke sheets and iron core column, and form by the very thin silicon steel sheet stack of slices, it is relatively more difficult when mounting coil that the cross section of the core structure of transformer is generally the core structure of Long Circle cross section, and 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, comprise iron core column and iron yoke, and the cross section of described iron core column and described iron yoke is ellipse.
Adopt technique scheme, the cross section of iron core column and iron yoke is ellipse, because the oval length that has shortened the iron yoke makes silicon steel sheet reduce consumption, has reduced no-load loss.So satisfying under the prerequisite of national standard, the non-circular cross-section iron core can be than the close height of the magnetic of positive circular cross section iron core a bit.The close height of magnetic a bit means that just wire turn can lack, and saves the consumption of electromagnetic wire so again.
The beneficial effects of the utility model are: because the oval length that has shortened the iron yoke makes silicon steel sheet reduce consumption, reduced no-load loss.So satisfying under the prerequisite of national standard, the non-circular cross-section iron core can be than the close height of the magnetic of positive circular cross section iron core a bit.The close height of magnetic a bit means that just wire turn can lack, and saves the consumption of electromagnetic wire so again.Consume because of silicon steel sheet, electromagnetic wire again and lacked, dry-type transformer overall dimension has diminished, and the shell of dry-type transformer also can correspondingly reduce.Finally reach the effect that total cost significantly descends.
(4) description of drawings
Fig. 1 is the structural representation of the cross section of iron core column of the present utility model.
Fig. 2 is a core structure schematic diagram of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of core structure of dry-type transformer is made up of iron yoke 2 and iron core column 1, and described iron yoke 2 is ellipse with the shape of cross section of described iron core column 1.Because thereby the shape of cross section of iron core column 1 makes silicon steel sheet reduce consumption, thereby has reduced no-load loss for the oval length that has shortened iron yoke 2.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.
Adopt the dry-type transformer iron core 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 dry-type transformer iron core structural iron stem stem, thereby reduced the manufacturing cost of dry-type transformer, raw material have been saved, and clamp conveniently, can on existing structure, not change clamping mode and clamp core structure.
Claims (1)
1. the core structure of a transformer comprises iron core column and iron yoke, it is characterized in that: the cross section of described iron core column and described iron yoke is ellipse.
