Abstract
The utility model discloses a transformer core which is formed by superimposing a plurality of sets of silicon steel sheets; each set of silicon steel sheets comprises an upper iron yoke monomer, a lower iron yoke monomer, and a core column monomer vertically connected between the upper iron yoke monomer and the lower iron yoke monomer, wherein the upper iron yoke monomer and the lower iron yoke monomer are arranged horizontally; the upper iron yoke monomers jointly constitute an upper iron yoke, the lower iron yoke monomers jointly constitute a lower iron yoke, the core column monomers jointly constitute a core column, and the cross section of the core column constituted by the core column monomers is elliptical; and among the upper iron yoke monomers constituting the upper iron yoke, the horizontal center lines of the upper iron yoke monomers positioned on two sides are lower than the horizontal center line of the upper iron yoke monomer in the middle. The transformer core has the advantages that material is saved, and cost is lowered.
Description
Technical field
The utility model relates to a kind of iron core, is meant a kind of transformer core especially.
Background technology
The iron core of transformer is an important components of transformer; Present iron core mainly is to have that silicon steel sheet is stacked to form; Same size and highly consistent one group of silicon steel sheet of formation, every group of silicon steel sheet comprises horizontally disposed upper yoke monomer and lower yoke monomer, vertically is connected in the stem stem monomer between upper yoke monomer and the lower yoke monomer; The common stacked formation upper yoke of upper yoke monomer; The common stacked formation lower yoke of lower yoke monomer, the common stacked formation stem stem of stem stem monomer, and the cross section of present upper yoke and lower yoke mainly contains circle, oval or rectangle; And the horizontal center line of each upper yoke monomer is concordant, the horizontal center line of lower yoke monomer is concordant, but the length of these structure stem stems also has the space of shortening.
The utility model content
The utility model technical problem to be solved is: a kind of transformer core that can save material, reduce cost is provided.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of transformer core; Said iron core is by some groups of stacked the forming of silicon steel sheet; Every group of silicon steel sheet comprises horizontally disposed upper yoke monomer and lower yoke monomer, vertically is connected in stem stem monomer between upper yoke monomer and the lower yoke monomer, and said upper yoke monomer constitutes upper yoke jointly, and said lower yoke monomer constitutes lower yoke jointly; Said stem stem monomer constitutes stem stem jointly, and the stem stem cross section that said stem stem monomer constitutes is oval; Constitute in the upper yoke monomer of upper yoke, the horizontal center line that is positioned at the upper yoke monomer of both sides is lower than the horizontal center line of middle upper yoke monomer.
As a kind of preferred version, constitute in the lower yoke monomer of lower yoke, the horizontal center line that is positioned at the lower yoke monomer of both sides is higher than the horizontal center line of middle lower yoke monomer.
After having adopted technique scheme; The effect of the utility model is: because a kind of transformer core; Said iron core is by some groups of stacked the forming of silicon steel sheet; Every group of silicon steel sheet comprises horizontally disposed upper yoke monomer and lower yoke monomer, vertically is connected in stem stem monomer between upper yoke monomer and the lower yoke monomer, and said upper yoke monomer constitutes upper yoke jointly, and said lower yoke monomer constitutes lower yoke jointly; Said stem stem monomer constitutes stem stem jointly, and the stem stem cross section that said stem stem monomer constitutes is oval; Constitute in the upper yoke monomer of upper yoke; The horizontal center line that is positioned at the upper yoke monomer of both sides is lower than the horizontal center line of middle upper yoke monomer, and therefore, the upper yoke monomer of both sides and the distance of lower yoke monomer reduce; Like this; The length of stem stem just can reduce, thereby has practiced thrift material, has reduced cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the front schematic view of the utility model embodiment;
Fig. 2 is the profile of Fig. 1 at the A-A place;
Fig. 3 is the profile of Fig. 1 at the B-B place;
In the accompanying drawing: 1. upper yoke; 11. middle upper yoke monomer; 12. the upper yoke monomer of both sides; 13. middle upper yoke single level center line; 14. the upper yoke single level center line of a side; 2. lower yoke; 3. stem stem; 31. stem stem monomer.
Embodiment
Through specific embodiment the utility model is done further to describe in detail below.
A kind of transformer core; Like Fig. 1, Fig. 2 and shown in Figure 3, said iron core is by some groups of stacked the forming of silicon steel sheet, and every group of silicon steel sheet comprises horizontally disposed upper yoke monomer and lower yoke monomer, vertically is connected in stem stem monomer 31 between upper yoke monomer and the lower yoke monomer; Said upper yoke monomer constitutes upper yoke 1 jointly; Said lower yoke monomer constitutes lower yoke 2 jointly, said stem stem monomer 31 common formation stem stems 3, and stem stem 3 cross sections that said stem stem monomer 31 constitutes are oval; Constitute in the upper yoke monomer of upper yoke 1; The horizontal center line that is positioned at the upper yoke monomer 12 of both sides is lower than middle upper yoke single level center line 13; As shown in Figure 3; The upper yoke monomer 12 of both sides is with respect to middle upper yoke monomer 11 symmetric arrangement, and the upper yoke single level center line 14 of a side is lower than middle upper yoke single level center line 13, and the height of whole iron core is to remain unchanged; In the upper yoke monomer 12 of both sides; Several groups of lower surfaces near middle upper yoke monomer 11 are concordant with the lower surface of middle upper yoke monomer 11, and the upper surface of upper yoke monomer 11 and the distance of lower surface did not influence the use of iron core in the middle of the ultimate range of upper surface and lower surface remained.
In order further to shorten the length of stem stem 3, constitute in the lower yoke monomer of lower yoke 2, the horizontal center line that is positioned at the lower yoke monomer of both sides is higher than the horizontal center line of middle lower yoke monomer.Principle is identical with the principle of upper yoke 1; Because the horizontal center line of lower yoke monomer in the middle of the horizontal center line of the lower yoke monomer of both sides is higher than; Therefore, distance further shortens between the center line of the horizontal center line of upper yoke monomer and lower yoke monomer, and then has shortened the length of stem stem 3; Save material, reduced cost.
Claims (2)
1. transformer core; Said iron core is by some groups of stacked the forming of silicon steel sheet; Every group of silicon steel sheet comprises horizontally disposed upper yoke monomer and lower yoke monomer, vertically is connected in stem stem monomer between upper yoke monomer and the lower yoke monomer, and said upper yoke monomer constitutes upper yoke jointly, and said lower yoke monomer constitutes lower yoke jointly; Said stem stem monomer constitutes stem stem jointly, it is characterized in that: the stem stem cross section that said stem stem monomer constitutes is for oval; Constitute in the upper yoke monomer of upper yoke, the horizontal center line that is positioned at the upper yoke monomer of both sides is lower than the horizontal center line of middle upper yoke monomer.
