Description
Technical field
The present invention relates to a kind of transformer cores, and in particular to a kind of stereo amorphous alloy wound iron core molding structure belongs to
Amorphous transformer core fabricates field.
Background technology
Existing three-phase amorphous alloy transformer core column section is rectangular, and core structure is mostly four frames, five column or three frames
Three columns.
Shortcoming that there are many this transformer iron-core structures, the first rectangular section of iron core column are than circular cross section in coil turn
In the case that number is identical, to consume 11.1% copper material more；Secondly every transformer single frame iron core is relatively more (by single or double
Composition), iron yoke gap mitre will increase, and magnetic resistance increases therewith, during transformer station high-voltage side bus, under the action of alternating current magnetic field,
Its seam crossing easily causes many places low frequency shaking, so as to generate very big noise.In addition, the magnetic flux density in the iron yoke of this iron core
It is 1.155 times of magnetic flux density in iron core column, therefore it also results in the no-load loss increase of iron core.
Existing triangle winding iron core transformer is to remain silent, and coil winding needs professional coil winding machine, corporate device input ratio
Larger, manufacture efficiency is low, and processing technology is complicated, and changing of coils is complicated.
The content of the invention
The defects of the purpose of the present invention is overcoming the prior art, provides a kind of stereo amorphous alloy wound iron core molding structure,
The no-load loss of iron core can be reduced, reduce the noise of transformer, and save copper material, oil, iron that coil is consumed etc..
Realizing the technical solution of above-mentioned purpose is：A kind of stereo amorphous alloy wound iron core molding structure, including iron core column sheet
Body, the upper yoke positioned at iron core column body upper end and the lower yoke positioned at iron core column body lower end, wherein：
The iron core column body is made of mutually independent three iron core columns, and the shape and size of each iron core column are equal
Identical, the circular in cross-section of each iron core column, each iron core column is single-phase open core, each iron
Along it, axially there are one rectangular through-holes for setting at the center of stem；
Three iron core columns are respectively the first iron core column, the second iron core column and the 3rd iron core column, first iron core column,
Second iron core column and the 3rd iron core column are set according to triangular solid arrangement architecture, and the circle of the first iron core column cross section
The center of circle of the heart, the center of circle of the second iron core column cross section and the 3rd iron core column cross section forms an equilateral triangle；
The shape of the upper yoke and lower yoke is identical with size, and the thickness of the upper yoke and the thickness of lower yoke are impartial
In the diameter of the iron core column；
The upper yoke or lower yoke are can Unclosing structure.
A kind of above-mentioned stereo amorphous alloy wound iron core molding structure, wherein, the height of each iron core column is identical, often
A iron core column is wound into cylinder docking by non-crystaline amorphous metal mixing polygon band or silicon steel mixing polygon band and forms.
A kind of above-mentioned stereo amorphous alloy wound iron core molding structure, wherein, the upper yoke and lower yoke are by non-
The rectangle frame that peritectic alloy mixing polygon band or silicon steel mixing polygon band winding form.
The stereo amorphous alloy wound iron core molding structure of the present invention, employs triangular solid arrangement architecture, each iron yoke
Length is identical and most short, and iron core column with iron yoke is wound by non-crystaline amorphous metal or silicon steel mixing polygon band, iron core column
Section is rounded, and iron core column section fill factor is high, and the high coefficient of stock utilization is 0.98 or so, therefore transformer noload losses
Small, low noise saves copper material, oil, iron etc., it is often more important that due to iron core column opening, it is difficult to overcome volume iron core winding of remaining silent
The shortcomings that, transformer coil can independent coiling, identical with current plane amorphous iron core capacity various distribution oil can be manufactured
Soak transformer and dry-type transformer.

Specific embodiment
It is right below in conjunction with the accompanying drawings in order to which those skilled in the art is made to be better understood when technical scheme
Its specific embodiment is described in detail：
It please refers to Fig.1, Fig. 2, Fig. 3 and Fig. 4, highly preferred embodiment of the present invention, a kind of stereo amorphous alloy wound iron core shaping
Structure, the upper yoke 1 including iron core column body, positioned at iron core column body upper end and the lower yoke 2 positioned at iron core column body lower end.
Iron core column body is made of mutually independent three iron core columns, shape and the size all same of each iron core column, each iron core column
Circular in cross-section, each iron core column is single-phase open core, and the center of each iron core column is provided with one along its axial direction
A rectangular through-hole；Three iron core columns are respectively the first iron core column 3, the second iron core column 4 and the 3rd iron core column 5, the first iron core column 3,
Second iron core column 4 and the 3rd iron core column 5 are set according to triangular solid arrangement architecture, and the center of circle of 3 cross section of the first iron core column
A1,4 cross section of the second iron core column 5 cross section of center of circle a2 and the 3rd iron core column center of circle a3 form an equilateral triangle；On
Iron yoke 1 and the shape of lower yoke 2 are identical with size, and the thickness of upper yoke 1 and the thickness of lower yoke 2 are equal to the diameter of iron core columnUpper yoke or lower yoke for can Unclosing structure, i.e., being there are one iron yoke in upper yoke and lower yoke can Unclosing structure.
The height of each iron core column is identical, and each iron core column is more by non-crystaline amorphous metal mixing polygon band or silicon steel mixing
Side shape band is wound into cylinder docking composition.Upper yoke 1 and lower yoke 2 are by non-crystaline amorphous metal mixing polygon band or silicon steel
The rectangle frame that mixing polygon band winding forms.
Entire core body is assembled by the angle of 120 ° of central angle by the identical single-phase open core column of three shapes
It is composed, the center of circle of such three iron core column cross sections forms an equilateral triangle.
Again referring to Fig. 4, the cross section 6 of non-crystaline amorphous metal mixing polygon band or silicon steel mixing polygon band is in one
