Abstract
A structure for an iron core column silicon steel sheet of a transformer is formed by splicing a left trapezoidal silicon steel sheet body and a right trapezoidal silicon steel sheet body. An upper part and a lower part are formed by splicing the left trapezoidal silicon steel sheet body and the right trapezoidal silicon steel sheet body and respectively form a corresponding triangle. The structure for the iron core column silicon steel sheet of the transformer is formed by splicing the left trapezoidal silicon steel sheet body and the right trapezoidal silicon steel sheet body, leftover materials of the silicon steel sheet will not be produced when the spliced trapezoidal silicon steel sheet is cut transversely, so that the utilization rate of the silicon steel sheet is greatly increased, and the production cost of the transformer is lowered.
Description
Technical field
The utility model relates to a kind of transformer device, particularly a kind of insulating end ring of transformer.
Background technology
At present, the price of silicon steel sheet rises steadily, and occupies the cost that transformer is very large.As shown in Figure 1, silicon steel sheet top is triangle to the structure of common transformer core stem stem silicon steel sheet, and it adopts cut-to-length to produce conventionally, and its horizontal shearing process as shown in Figure 2.Because its top is triangle, in processing, silicon steel sheet is horizontal while cutting, the corner material area that can produce is larger, wastes more serious.Along with the wide increase of sheet, the corner material of generation is also many, especially high-power transformer, and its corner material amount is very large.Because corner material is less than normal, processing technology is poor, and corner material is processed as waste material conventionally, and the utilance of silicon steel sheet is low, has caused very large waste.Current, along with carrying forward vigorously that national energy-saving reduces discharging, for Transformer Manufacturing Enterprises, reduce material consumption, cost-saving, become the main development pattern that strengthens enterprise competitiveness.
Utility model content
The utility model aims to provide a kind of structure of transformer core stem stem silicon steel sheet, can eliminate the corner material of silicon steel sheet, improves the utilance of silicon steel sheet, reduces the production cost of transformer.
The purpose of this utility model is to realize by such technical scheme:
A structure for transformer core stem stem silicon steel sheet, is characterized in that being spliced by the trapezoidal silicon steel sheet in two of left and right, and the top and the bottom that the trapezoidal silicon steel sheet in two of left and right is spliced form respectively corresponding triangle.
Owing to adopting the two trapezoidal silicon steel sheets in left and right to be spliced, trapezoidal silicon steel sheet splices in the time of horizontal cutting, and there is no the corner material of silicon steel sheet, improves widely the utilance of silicon steel sheet, has reduced the production cost of transformer.
When concrete enforcement, the angle of the triangle drift angle of the top and the bottom that the trapezoidal silicon steel sheet in two of left and right is spliced is 90 degree.
When concrete enforcement, described silicon steel sheet thickness is 0.23-0.5mm.Adopt the silicon steel sheet closed assembly that thickness is 0.23-0.5mm to form, to reduce the loss of iron core.
The beneficial effects of the utility model are: owing to adopting the two trapezoidal silicon steel sheets in left and right to be spliced, trapezoidal silicon steel sheet splices in the time of horizontal cutting, and there is no the corner material of silicon steel sheet, improves widely the utilance of silicon steel sheet, has reduced the production cost of transformer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, utility model is further illustrated.
Fig. 1 is the structural representation of the transformer core stem stem silicon steel sheet of prior art.
Fig. 2 is the horizontal schematic diagram of cutting of the transformer core stem stem silicon steel sheet of prior art.
Fig. 3 is the structural representation of the utility model embodiment transformer core stem stem silicon steel sheet.
Fig. 4 is the horizontal schematic diagram of cutting of the utility model embodiment transformer core stem stem silicon steel sheet.
In figure: 1, left 2, right.
Embodiment
Below in conjunction with drawings and Examples, the utility model is done in further non-limiting description: Fig. 2, Fig. 3, a kind of structure of transformer core stem stem silicon steel sheet, be spliced by left 1 and right 2, left 1 and right 2 is trapezoidal silicon steel sheet, silicon steel sheet thickness is 0.23mm, the top and the bottom that left 1 and right 2 trapezoidal silicon steel sheet are spliced form respectively corresponding triangle, and the angle of triangle drift angle is 90 degree.
Because the trapezoidal silicon steel sheet that adopts left 1 and right 2 is spliced, trapezoidal silicon steel sheet splices in the time of horizontal cutting, and as shown in Figure 4, there is no the corner material of silicon steel sheet, improves widely the utilance of silicon steel sheet, has reduced the production cost of transformer.
Finally, it is also to be noted that, what more than enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive or associate from disclosed content of the present utility model, all should think protection range of the present utility model.
