Iron core is magnetic circuit part main in transformer, usually higher by silicon content, surface scribbles the hot rolling of insulating varnish and cold-reduced silicon sheet closed assembly forms, iron core and form complete EM induction system around coil thereon, and the through-put power of power transformer depends on material and the cross-sectional area of iron core.Therefore, the structure of iron core generally adopts layered laminate.
Now common oil-filled transformer core structure, first order iron core, second level iron core, third level iron core and fourth stage iron core etc. are all that centrally line is symmetrical, especially the part that is connected with window of iron core, directly can not can be regarded as area of dissipation, therefore, be equivalent to cause core material to waste, and the heavier-weight of iron core, transformer noload losses is large, and the function of transformer reduces.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of oil-filled transformer core structure, and this structure can reduce the consumption of core material, provides cost savings, weight reduction, and reduces transformer noload losses, improves the performance of iron core.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of oil-filled transformer core structure, it iron core comprising window and be arranged on described window two ends, described iron core forms by multistage lamination is stacked, wherein one end of first order lamination, second level lamination, third level lamination and fourth stage lamination flushes with described window interior, and the other end of described first order lamination, second level lamination, third level lamination and fourth stage lamination is symmetrical along the vertical direction center line of core structure.
In a preferred embodiment of the present utility model, comprise further, one end that described iron core is connected with described window, multistage lamination except described first order lamination, second level lamination, third level lamination and fourth stage lamination stacks gradually, and all along the center line symmetry of core structure.
In a preferred embodiment of the present utility model, comprise further, the center line of the window be connected with every one-level lamination also along core structure is symmetrical.
In a preferred embodiment of the present utility model, comprise further, described iron core is fixed by folder, and each iron core is fixed by two folders.
In a preferred embodiment of the present utility model, comprise further, described folder is concave structure, the slot opening direction iron core all dorsad of two folders of fixing same iron core.
In a preferred embodiment of the present utility model, comprise further, the core structure be made up of described window and iron core is column structure.
The beneficial effects of the utility model are:
The utility model provides a kind of oil-filled transformer core structure, one end of one-level lamination, second level lamination, third level lamination and fourth stage lamination flushes with described window interior, this structure can reduce the consumption of core material, provide cost savings, weight reduction, and reduce transformer noload losses, improve the performance of iron core.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment technology, be briefly described to the accompanying drawing used required in the description of embodiment technology below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Wherein, 1-first order lamination, 2-second level lamination, 3-third level lamination, 4-fourth stage lamination, 5-folder, 6-window.
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.
Embodiment
As shown in Figure 1, a kind of oil-filled transformer core structure is disclosed in the present embodiment, it iron core comprising window 6 and be arranged on above-mentioned window 6 two ends, the core structure that above-mentioned window 6 and the iron core being arranged on its two ends form is column structure, and this structure is to axial symmetry, the center line namely along core structure is symmetrical.
Above-mentioned iron core forms by multistage lamination is stacked, wherein first order lamination 1, second level lamination 2, third level lamination 3 and fourth stage lamination 4 and window 6 be directly connected one end, this end and above-mentioned window 6 internally flush, and the other end of above-mentioned first order lamination 1, second level lamination 2, third level lamination 3 and fourth stage lamination 4 is symmetrical along the vertical direction center line of core structure.
One end of one-level lamination 1, second level lamination 2, third level lamination 3 and fourth stage lamination 4 flushes with described window interior, this structure can reduce the consumption of core material, provides cost savings, weight reduction, and reduce transformer noload losses, improve the performance of iron core.
One end that above-mentioned iron core is connected with above-mentioned window, the multistage lamination except above-mentioned first order lamination 1, second level lamination 2, third level iron core 3 and fourth stage lamination 4 stacks gradually, and all along the center line symmetry of core structure.
Because this structure is axially symmetric structure, the center line of the window be therefore connected with every one-level lamination also along core structure is symmetrical.
In the present embodiment, above-mentioned iron core is fixed by folder 5, and each iron core is fixed by two folders 5; Above-mentioned folder is concave structure, the slot opening direction iron core all dorsad of two folders of fixing same iron core.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
