Abstract
The utility model belongs to the transformer technology field, relates to a kind of transformer core stem splicing construction.Its stem unshakable in one's determination is made of stem slice, thin piece splicing stack unshakable in one's determination, the stem slice, thin piece unshakable in one's determination that splices is the slice, thin piece of several (being generally 5 kinds) different length, the length of these several different length slice, thin pieces from big to small, the length difference of adjacent two slice, thin pieces equates, at every kind of slice, thin piece upper punch location hole, several slice, thin pieces by the order stack of length increasing or decreasing together, by the location hole snap, this group slice, thin piece waits the ladder of width with regard to formation on the limit of length direction, and the limit of slice, thin piece Width is concordant, such one group of slice, thin piece slice, thin piece similar to another group shape splices by the location hole snap, formed a jointing line, be spliced to form ladder (stepping) jointing lines such as several at stepped limit and yoke sheet unshakable in one's determination, each seam all is to be spliced to form by individual slice, thin piece.
Description
Technical field
The utility model belongs to the transformer technology field, relates to the longitudinal spliced structure of a kind of oversize transformer stem unshakable in one's determination.
Background technology
Continuous increase along with separate unit power transformer capacity, the diameter of transformer core stem also increases thereupon, the sheet molded breadth degree of stem main and inferior main etc. has exceeded horizontal maximum working ability of cutting equipment, the width that has even surpassed standard silicon coil of strip material like this.The method of head it off is with super what wide stem slice, thin piece on the industry, adopt longitudinal spliced structure, splicing construction adopts the method for two one folded two seams, lamination diagram is seen Fig. 1, the cutaway view of seam crossing is seen Fig. 2, by the longitudinal spliced structure of this stem unshakable in one's determination, solved the cut-parts problem of the super wide slice, thin piece of oversize transformer stem unshakable in one's determination.But, the longitudinal spliced structure of this stem unshakable in one's determination since adopt two folded to homogeneous, and lamination do not have the location, hole, lamination efficient is low, is unfavorable for the batch process of product.
Summary of the invention
Technical problem to be solved in the utility model is will be at weak point of the prior art, a kind of new transformer core stem splicing construction is provided, to improve the longitudinal spliced lamination efficient of present stem unshakable in one's determination, reduce the no-load current and the no-load loss of oversize transformer.
The technical scheme that solves the utility model technical problem is that this transformer core stem splicing construction is made of slice, thin piece splicing stack unshakable in one's determination, the stem slice, thin piece unshakable in one's determination that splices is the slice, thin piece of several (being generally 5 kinds) different length, the length of these several different length slice, thin pieces from big to small, the length difference of adjacent two slice, thin pieces equates, at every kind of slice, thin piece upper punch location hole, these several slice, thin pieces by the order stack of length increasing or decreasing together, by the location hole snap, this group slice, thin piece waits the ladder of width with regard to formation on the limit of length direction, and the limit of Width is concordant, such one group of slice, thin piece slice, thin piece similar to another group shape splices by the location hole snap, formed a jointing line, be spliced to form ladder (stepping) jointing lines such as several at stepped limit and yoke sheet unshakable in one's determination, each jointing line generally all is to be spliced to form by individual slice, thin piece.

Embodiment
Below in conjunction with embodiment, accompanying drawing the utility model is further specified.
Be example now, the longitudinal spliced concrete grammar of this stem unshakable in one's determination of the utility model (1) is described with 5 grades of steppings (waiting step-lap laminated).In order to realize the stepping splicing, when slitting,, will be cut into two kinds of different width with the silicon steel coiled strip of one-level according to the design width.When cutting out sheet, the stem slice, thin piece unshakable in one's determination (4) that makes these two kinds of width is along its length with the certain size stepping horizontal, and 5 is one group.Utilize the horizontal circular hole punch press of cutting equipment, the stem slice, thin piece unshakable in one's determination (4) of these 5 kinds of different lengths is rushed to location hole (2) along its length, make the limit of every group of slice, thin piece by back, location hole location length direction the ladder of width such as all form.During lamination, two groups on same aspect stem slice, thin pieces unshakable in one's determination (4) are put by the location hole (2) of slice, thin piece, make concordant limit to good, the limit of length direction all forms the ladder of width such as (steppings), (see figure 5) staggers about the jointing line (5) of jointing line of aspect (5) and splicing subsurface in the splicing, the part of stepping simultaneously is by being spliced to form step-lap laminated line (6) with yoke sheet unshakable in one's determination (3), two groups is that an aspect stacks up to one-level and folded like this, has so just realized that 5 grades of steppings of stem unshakable in one's determination (1) are longitudinal spliced.
Compare with laminating method with the core construction of existing splicing unshakable in one's determination, the core construction and the laminating method of the multistage stepping splicing that the utility model adopted improve the core lamination seam quality greatly, thereby have reduced no-load current, the no-load loss of transformer.Simultaneously, can improve lamination efficient, the lamination time drops to original half.
