Description
Technical field
The utility model belongs to power transmission and distribution equipment technology, is related to transformer, more particularly to a kind of energy-economic transformer is used
Yoke piece.
Background technology
Transformer it is energy saving whether be an important indicator for examining transformer quality, general energy saving, low-coumption transformer,
Its energy-saving index includes idling load-loss and raw material loss objective.Many producers select in terms of Optimum Design of Transformers for this
Many schemes, wherein optimization core design is a key.The one kind of S13 serial transformers as energy-economic transformer,
It is widely used in residential block.Since the product uses the silicon steel sheet 27QH85 or 27QH90 of price costly in design
Piece, cost is higher, seriously constrains the effect of enterprise, is unfavorable for the development steady in a long-term of enterprise.
Utility model content
The utility model for technical problem existing for above-mentioned S13 serial transformer iron cores, propose a kind of design rationally,
Of simple structure and low cost and good energy-conserving effect, cheap energy-economic transformer yoke piece.
In order to achieve the above object, the technical solution adopted in the utility model is that the utility model provides a kind of energy saving change
Depressor yoke piece, including yoke piece body, the yoke piece body include the rectangular portion of rectangular setting and are arranged on square
The trapezoidal portion of the trapezoidal shape in shape side, the side of the trapezoidal portion away from rectangular portion are provided with delthyrium, and the delthyrium is set
In middle position of the trapezoidal portion away from the side away from rectangular portion, the width of the rectangular portion is 20~50mm.
Preferably, the delthyrium is designed in isosceles right triangle, the vertex of the delthyrium and trapezoidal portion side
Line be vertically arranged.
Compared with prior art, it is the advantages of the utility model with good effect,
1st, the utility model provides a kind of energy-economic transformer yoke piece, by varying the shape of traditional yoke piece, increases
The surface area of big yoke piece, and then the requirement or reduction of yoke piece material can be reduced in the case where ensureing that no-load loss is constant
The transformer coil number of turn, while reaching reduction production cost, it is also possible to not change yoke piece material and transformer
In the case of coil turn, no-load loss is further reduced, saves electric power resource.
Brief description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
The attached drawing used is briefly described, it should be apparent that, drawings in the following description are some embodiments of the utility model,
For those of ordinary skill in the art, without having to pay creative labor, can also be obtained according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the structure diagram of traditional yoke piece；
Fig. 2 is the structure diagram for the yoke piece that the present embodiment 1 provides；
More than in each figure, 1, yoke piece body；2nd, rectangular portion；3rd, trapezoidal portion；4th, delthyrium.
Embodiment
It is below in conjunction with the accompanying drawings and real in order to be more clearly understood that the above-mentioned purpose of the utility model, feature and advantage
Example is applied to be described further the utility model.It should be noted that in the case where there is no conflict, embodiments herein and reality
Applying the feature in example can be mutually combined.
Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality
New to implement using different from other modes described here, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment 1, as shown in Figure 1 and Figure 2, the present embodiment provides a kind of energy-economic transformer yoke piece
Yoke piece with traditional trapezoidal shape is not both the energy-economic transformer yoke piece that the present embodiment is provided, including
Yoke piece body, specifically, the rectangular portion 2 of yoke piece body 1 including rectangular setting and is arranged on 2 side of rectangular portion and is in
The trapezoidal portion 3 of trapezoidal shape, the trapezoidal portion 3 and the shape and size of traditional yoke piece that the present embodiment is provided are completely the same,
The side in trapezoidal portion 3 is provided with delthyrium 4, and delthyrium 4 is designed in isosceles right triangle, the vertex of delthyrium 4 with it is trapezoidal
The line of 3 side of portion is vertically arranged the side of delthyrium side, and the vertex of such delthyrium 4 is at trapezoidal 3 or so two, portion
Middle position on the center line on side (or upper bottom and bottom), the improved place of the present embodiment emphasis are setting for rectangular portion 2
To put, rectangular portion 2 is arranged on trapezoidal side of the portion 3 away from delthyrium 4, and rectangular portion 2 is exactly and trapezoidal 3 integrally formed plate of portion,
Its length is consistent with the length of trapezoidal 3 long side of portion, and width is set according to the concrete model of transformer, the scope of width 20~
Between 50mm, the width of rectangular portion 2 is an important factor for decide whole yoke piece no-load loss, it may be said that and by material
The principal element of replacement, in the present embodiment, the width of rectangular portion used in S13-M-630 transformers are 50mm, S13-M-
The width of rectangular portion used in 300 transformers is 20mm.
By above-mentioned setting, traditional transformer iron core structure is the yoke piece piece of the center pillar of iron core, side column and iron core
It is wide consistent, thick also consistent, therefore the center pillar of transformer core is folded, side column is identical with the sectional area of iron yoke, its magnetic flux density also phase
Together, and the yoke piece of the utility model is wide more roomy than side column and middle column sheet, it is but folded thick identical, therefore the sectional area of iron yoke will
Sectional area than center pillar, side column is big, and in the case where the transformer coil number of turn is identical, the magnetic flux density of iron yoke is than center pillar, side column
Magnetic flux density want low more, if the silicon steel sheet material of iron core is constant, the no-load loss on center pillar and side column is constant, and iron yoke
No-load loss to reduce it is more, for maintain transformer total no-load loss it is constant, can use the low trade mark silicon steel sheet generation
, can be by reducing transformer if maintaining the silicon steel sheet trade mark of intrinsic iron core for the silicon steel sheet of the intrinsic high trade mark
Coil turn, to achieve the purpose that to maintain former design no-load loss, so in the case where silicon steel sheet dosage is basically unchanged, is reduced
The dosage of coil copper wire and transformer oil, reduces the height of oil tank of transformer, reduces rolled steel dosage, so as to reduce transformation
The cost of device, improves the benefit of enterprise.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change is applied to other fields, but every without departing from the content of the technical scheme of the utility model, according to this reality
Any simple modification, equivalent variations and the remodeling made with new technical spirit to above example, it is new to still fall within this practicality
The protection domain of type technical solution.
