Abstract
The utility model belongs to the field of transformer equipment and particularly relates to an iron core structure of an oil immersed transformer. The iron core structure of the oil immersed transformer comprises an iron core, wherein the outer side of the iron core is wound with a low-voltage coil, and the outer side of the low-voltage coil is provided with a high-voltage coil. The iron core structure is characterized in that the cross section of the iron core is in a long circular shape. The iron core structure has the advantages that the structure of the iron core is improved, under the condition that the work requirement is met, the size of the transformer can be effectively reduced, materials are saved, and the cost is reduced.
Description
Technical field
The utility model belongs to the transformer equipment field, particularly a kind of core structure of oil-filled transformer.
Background technology
The iron core of transformer is important parts of transformer, present iron core mainly is to form by silicon steel sheet is stacked, same size and highly consistent one group of silicon steel sheet of formation, every group of silicon steel sheet comprises horizontally disposed upper yoke and lower yoke, be vertically connected on the stem stem between upper yoke and the lower yoke, the cross section of existing iron core mainly contains circle, ellipse or rectangle, but the iron core of this spline structure also has improved space.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of saving material, reduces the iron core of the oil-filled transformer of cost.
The utility model is achieved through the following technical solutions:
The core structure of oil-filled transformer, it comprises iron core, and the outside of iron core is wound with low-voltage coil, and the arranged outside of low-voltage coil has high-tension coil, it is characterized in that: the cross section of described iron core is oval shape.
Described iron core comprises the OBL center pillar that is arranged on the iron core axis, the bilateral symmetry of described center pillar is provided with by a plurality of post sheets, described post sheet is made of a plurality of post lamellas, the length of described post lamella reduces successively, and the axis of the center line of described post lamella and center pillar is on same straight line.
In sum, the utility model has changed the shape of iron core, in the situation of the job requirement of satisfying transformer, the iron core of oil-filled transformer described in the utility model can effectively dwindle the volume of transformer, reduce and produce the needed material of transformer, saved material, reduced cost.
Description of drawings
Fig. 1 is the schematic diagram of the core structure of traditional oil-filled transformer;
Fig. 2 is the schematic diagram of core structure of the present utility model;
Among the figure, 1 is iron core, and 2 is low-voltage coil, and 3 is high-tension coil, and 11 is center pillar, and 13 is the post sheet.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
The core structure of oil-filled transformer as depicted in figs. 1 and 2, it comprises iron core 1, and the outside of iron core 1 is wound with low-voltage coil 2, and the arranged outside of low-voltage coil 2 has high-tension coil 3, it is characterized in that: the cross section of described iron core 1 is oval shape.
Described iron core 1 comprises the OBL center pillar 11 that is arranged on the iron core axis, the bilateral symmetry of described center pillar 11 is provided with by a plurality of post sheets 13, described post sheet is made of a plurality of post lamellas, the length of described post lamella reduces successively, and the axis of the center line of described post lamella and center pillar is on same straight line.
In sum, the utility model has changed the shape of iron core, in the situation of the job requirement of satisfying transformer, the iron core of oil-filled transformer described in the utility model can effectively dwindle the volume of transformer, reduce and produce the needed material of transformer, saved material, reduced cost.
