Abstract
The utility model relates to a transformer core which is of a frame type structure composed of an iron core column and an iron yoke. The transformer core is characterized in that the cross sections of the iron core column and the iron yoke are elliptic. The utility model has the advantages that the iron core column and the iron yoke are elliptic, the folding assembly is convenient while the cross sectional area of the iron core column and the iron yoke are ensured, the distance between the two iron core columns can be reduced, and the height of an iron core frame is reduced, thereby shortening the length of an iron circuit, effectively reducing the wastage of a transformer, and reducing the volume of the transformer. The utility model is mainly applied to 10 to 110 kV transformers.
Description
(1) technical field
The utility model belongs to transformer core, particularly a kind of transformer core.
(2) background technology
Present stage, do not find and the identical structural design of the design.
(3) summary of the invention
The utility model provides the transformer core that a kind of closed assembly is convenient, transformer noload losses is low, volume is little in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
Transformer core of the present utility model, by the closed-in construction that iron core column, iron yoke are formed, its special character is: the equal ovalize of cross section of iron core column and iron yoke.
Transformer core of the present utility model, iron core column, iron yoke are made by cold rolling grain oriented silicon steel sheet, and seam construction between the two is 45 degree full bias seams.Sturdy and durable like this.
The beneficial effects of the utility model are, iron core column and iron yoke ovalize, when guaranteeing iron core column and iron yoke sectional area, closed assembly is convenient, can guarantee that also the distance between two iron core column reduces, iron core frame height reduces, thereby shortens iron circuit length, effectively reduce the loss of transformer, reduce volume of transformer.The utility model is mainly used in 10～110kV level transformer.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Fig. 1 is a front view.Fig. 2 is a vertical view.Fig. 3 is a left view.
Among the figure: 1 iron core column, 2 iron yokes.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Transformer core of the present utility model, by the three-phase closed-in construction that iron core column 1, iron yoke 2 are formed, its special character is: the equal ovalize of cross section of iron core column and iron yoke.Iron core column, iron yoke are made by the cold rolling grain oriented silicon steel sheet of high-quality, and seam construction between the two is 45 degree full bias seams.
Claims (2)
1, a kind of transformer core, the closed-in construction by iron core column (1), iron yoke (2) are formed is characterized in that: the equal ovalize of cross section of iron core column and iron yoke.
2, transformer core according to claim 1 is characterized in that: iron core column, iron yoke are made by cold rolling grain oriented silicon steel sheet, and seam construction between the two is 45 degree full bias seams.
