Abstract
The utility model discloses a kind of transformer core, comprise the framework surrounded by the iron yoke of the stem stem of three bursts of longitudinal directions and two bursts of transverse directions, the cross section of described stem stem is Long Circle, and the cross section of described iron yoke is flat shape, and the cross section of described stem stem is greater than the cross section of described iron yoke.By the iron yoke of transformer core is arranged in flat shape, avoid sectional area little with this, stressed inadequate problem, and ensure the power uniform force of folder shim core, handled easily, enhance productivity.
Description
Technical field
The utility model relates to the medium-small type distribution transformers field of power equipment, refers to a kind of transformer core especially.
Background technology
What the medium-small type distribution transformers of power equipment adopted is circular yoke core, as Chinese Authorization Notice No. be CN201233794Y patent discloses a kind of transformer core, be is become with iron yoke piece by iron core column, the cross section of iron core column and iron yoke is ellipse.In addition, the open patent of invention of China, publication number be CN103680845 patent discloses a kind of transformer core, be become with iron yoke piece by iron core column, the cross section of iron core column and iron yoke is Long Circle.Structure like this causes the sectional area of the shim core of folder little, not stressed, and can not operate preferably, causes certain puzzlement, reduce production efficiency to production, and this kind of transformer product is in a disadvantageous position in day by day fierce market competition.
Therefore, be necessary to provide a kind of novel transformer iron-core structure, to solve the problems of the technologies described above.
Summary of the invention
The utility model object is to provide a kind of transformer core, can ensure the power uniform force of folder shim core.
The technical solution of the utility model is achieved in that a kind of transformer core, comprise the framework surrounded by the iron yoke of the stem stem of three bursts of longitudinal directions and two bursts of transverse directions, it is characterized in that: the cross section of described stem stem is Long Circle, the cross section of described iron yoke is flat shape, and the cross section of described stem stem is greater than the cross section of described iron yoke.
Further, described stem stem and described iron yoke form by silicon steel sheet is stacked.
Further, described stem stem comprises the side column and middle center pillar that are positioned at both sides.
Further, the seam between described stem stem and described iron yoke junction is 45 degree.
The utility model is compared with prior art: by arranging the iron yoke of transformer core in flat shape, avoiding sectional area little, stressed inadequate problem, and ensureing the power uniform force of folder shim core, handled easily, enhance productivity with this.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the profile along A-A line in Fig. 1;
Fig. 3 is the profile along B-B line in Fig. 1.
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.
As shown in Figure 1, described transformer core, mainly comprises and is connected with the iron yoke 1 of two bursts of transverse directions the framework surrounded by the stem stem 2 of three bursts of longitudinal directions.The stem stem 1 of described three bursts of longitudinal directions comprises the side column being positioned at both sides and the center pillar being positioned at centre.Wherein, the seam between described stem stem and described iron yoke junction is 45 degree.
As shown in Figure 2, the cross section of described stem stem 2 is Long Circle, and described stem stem 2 forms by crystal silicon chip 3 is stacked, and the width of silicon steel sheet 3 at different levels reduces from main silicon steel sheet 3 gradually to both sides successively.
As shown in Figure 3, the cross section of described iron yoke 1 is flat shape, and the cross section of described stem stem 2 is greater than the cross section of described iron yoke 1.Described iron yoke 1 is also form by crystal silicon chip 3 is stacked, and the width of silicon steel sheet 3 at different levels reduces from main silicon steel sheet 3 gradually to both sides successively.
The utility model, by arranging in flat shape by the iron yoke 1 of transformer core, is avoided sectional area little with this, stressed inadequate problem, and is ensured the power uniform force of folder shim core, handled easily, enhance productivity.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
Claims (4)
1. a transformer core, comprise the framework surrounded by the iron yoke of the stem stem of three bursts of longitudinal directions and two bursts of transverse directions, it is characterized in that: the cross section of described stem stem is Long Circle, the cross section of described iron yoke is flat shape, and the cross section of described stem stem is greater than the cross section of described iron yoke.
2. transformer core according to claim 1, is characterized in that: described stem stem and described iron yoke form by silicon steel sheet is stacked.
