Abstract

The invention discloses a long-circle-shaped and D-shaped transformer iron core structure. The long-circle-shaped and D-shaped transformer iron core structure comprises a frame body formed by a longitudinal core column and a transverse iron yoke in an enclosing mode, wherein both the core column and the iron yoke are formed by silicon steel sheets in a stacked mode, and the cross section of the core column is in the shape of a long circle, and the cross section of the iron yoke is in the shape of D. According to the long-circle-shaped and D-shaped transformer iron core structure, the center distance of the iron core and the height of the iron core are both reduced, the number of magnetic circuits of the iron core is reduced, and therefore the purposes of reducing the weight of the iron core and reducing the cost are reduced. Meanwhile, no-load loss of the iron core is also reduced due to the long-circle-shaped transformer iron core structure, and stability of the iron core reaches national standards after being tested.

Description

Long Circle and D shape transformer core structure
Technical field
The present invention relates to medium-small type distribution transformers field, particularly a kind of core structure of transformer.
Background technology
The core structure that medium-small type distribution transformers is traditional is circular cross section, the advantage of its structure is that stability is high, and shortcoming is that iron core weight is larger, and raw materials is more, cause cost higher, this class power transformer product is in a disadvantageous position in day by day fierce market competition.
Summary of the invention
The object of the present invention is to provide a kind ofly can reduce iron core weight, thereby reach Long Circle and the D shape transformer core structure reducing costs.
Technical scheme of the present invention is as follows:
Long Circle and a D shape transformer core structure, comprise that described stem stem and iron yoke build up by silicon steel sheet by the framework that stem stem and horizontal iron yoke surround longitudinally, and the cross section of described stem stem is Long Circle, and the cross section of described iron yoke is D shape.
Useful technique effect of the present invention is:
The present invention passes through to reduce iron core weight, thereby reduces costs, and increases the market share, and the stability of iron core is up to state standards through test.
Advantage of the present invention will provide in embodiment description partly below, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
Fig. 2 is stem stem sectional view of the present invention.
Fig. 3 is iron yoke sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, transformer core of the present invention mainly by three strands longitudinally stem stem 1 and two strands of horizontal iron yokes 2 connect to form, form the framework of day font.Stem stem 1 of the present invention and iron yoke 2 build up by silicon steel sheet 3.
As shown in Figure 2, the cross section of stem stem 1 changes Long Circle into by traditional circle, and the area of section before and after change is constant.In area of section one timing of stem stem 1, the width of main silicon steel sheet 3 is reduced and controls to the thickness of main silicon steel sheet 3.The width of all the other silicon steel sheets 3 at different levels, from main silicon steel sheet 3, reduces successively to both sides, forms the cross section of oblong stem stem 1, and reaches oblong area of section and equate with traditional circular cross-sectional area.
As shown in Figure 3, the cross section of iron yoke 2 changes D shape into by traditional circle, and the area of section before and after change is constant.In area of section one timing of iron yoke 2, the width of main silicon steel sheet 3 is reduced and controls to the thickness of main silicon steel sheet 3.The width of all the other silicon steel sheets 3 at different levels, from main silicon steel sheet 3, reduces successively to both sides.An adjacent two layers silicon steel sheet 4 wherein side is consistent, opposite side indentation.The final cross section that forms the iron yoke 2 of D shape, and the area of section that reaches D shape equates with traditional circular cross-sectional area.
By the present invention, the centre-to-centre spacing (Mo) of iron core in Fig. 1 is reduced and the height (H) of iron core reduces, the magnetic circuit of iron core reduces, and reach and reduce iron core weight, thus the object reducing costs; And the present invention is also reduced iron core no-load loss.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the basic idea of the present invention, within all should thinking and being included in protection scope of the present invention.
