Abstract
The utility model relates to an amorphous alloy ring-shaped transformer iron core, consisting of three same iron core columns wound by amorphous alloy belts, an upper iron yoke and a lower iron yoke, wherein the upper iron yoke and the lower iron yoke are vertically butted, wherein the cross section of each iron core is round, the upper iron yoke and the lower iron yoke are rings which have the same shape and are wound by the amorphous alloy belts with equal width. A transformer manufactured by the amorphous alloy ring-shaped transformer iron core has the advantages that the iron loss is less, the noise is low, the material consumption is low and the production technique is simple, and the like.
Description
Technical field
The utility model relates to a kind of transformer core, specifically a kind of non-crystaline amorphous metal annular transformer core.
Background technology
Existing three-phase amorphous alloy transformer core all adopts four frames, five rod structures or three frames, three rod structures, and its iron core column cross section is rectangular.For the suit transformer coil, an end iron yoke of its single frame iron core all need disconnect for every layer, forms mitre, when the assembling coil, every layer of iron yoke is opened one by one at gap, and mounting coil closes up after on the iron core column more one by one, and seam crossing is bonding with glue special.
This core structure has many shortcomings, and at first the rectangular cross section of iron core column under the identical situation of coil turn, consume 11.4% copper material than circular cross section more; Secondly the end iron yoke owing to each single frame iron core all disconnects, and magnetic resistance increases, and the no-load loss of iron core increases thereupon, and when transformer moved in addition, its seam very easily caused low-frequency vibration under the effect of AC magnetic field, thereby produces very big noise.And the magnetic flux density in the iron yoke of this iron core is 1.155 times of magnetic flux density in the iron core column, so it has also caused the no-load loss of iron core to increase.
Summary of the invention
The purpose of this utility model is to design a kind of non-crystaline amorphous metal annular transformer core, to reduce the no-load loss of iron core, reduces noise of transformer, and saves the copper material that coil consumed.The technical scheme that provides according to the utility model, described non-crystaline amorphous metal annular transformer core, comprise iron core column and upper yoke that is positioned at the iron core column upper end and the lower yoke that is positioned at the iron core column lower end, it is characterized in that: independently formed separately by first iron core column, second iron core column and the 3rd iron core column by identical for described iron core column, each iron core column height is identical, the cylinder butt joint institute that is wound into same diameter by 2 or 2 above amorphous alloy strips is formed, and there is a manhole at each iron core column center; Described upper yoke is identical with lower yoke, and be respectively by etc. the amorphous alloy strips of width be wound into identical shaped annulus, the width of described annulus equals the diameter of iron core column; Described first iron core column, second iron core column and the 3rd iron core column respectively with upper and lower iron yoke vertical butt joint, and respectively with last, the interior circle and the cylindrical of lower yoke annulus are tangent; The center of circle of first iron core column, second iron core column and the 3rd iron core column cross section constitutes an equilateral triangle.
The utility model has the advantages that: because this transformer core has adopted the three-dimensional arrangement architecture of triangle, every phase iron yoke length is identical, and iron core column and iron yoke all are to be formed by the amorphous alloy strips continuous reeling, no seam and gap, and the iron core cross section is rounded.Therefore its no-load loss is little, and noise is low, saves copper material, and because iron core column and upper and lower iron yoke adopt the connecting mode of vertical butt joint, has greatly made things convenient for the suit of transformer high-voltage coil and low-voltage coil.

Embodiment
As shown in the figure: described non-crystaline amorphous metal annular transformer core, comprise iron core column and upper yoke 4 that is positioned at the iron core column upper end and the lower yoke 5 that is positioned at the iron core column lower end, independently formed separately by first iron core column 1, second iron core column 2 and the 3rd iron core column 3 by identical for described iron core column, each iron core column height is identical, the cylinder butt joint institute that is wound into same diameter by 2 or 2 above amorphous alloy strips is formed, and there is a manhole at each iron core column center; Described upper yoke 4 is identical with lower yoke 5, and is respectively the identical shaped annulus of being reeled and being formed by the amorphous alloy strips of width such as continuous, and the width of described annulus equals the diameter of iron core column cross section; Described first iron core column 1, second iron core column 2 and the 3rd iron core column 3 respectively with upper yoke 4 and lower yoke 5 vertical butt joint, and tangent with the interior circle and the cylindrical of the annulus of upper and lower iron yoke 4,5 respectively; The center of circle of the cross section of first iron core column 1, second iron core column 2 and the 3rd iron core column 3 constitutes an equilateral triangle
During manufacturing, whole non-crystaline amorphous metal annular transformer core comprises two parts, i.e. 3 identical iron core column and upper and lower iron yoke 4,5.Columniform plug on clamping on the up-coiler, to wait the amorphous alloy strip material of width closely fitly to be wound on the plug then, form a non-crystaline amorphous metal cylinder, after coiling finishes they are sent into special-purpose annealing furnace and under 300 ℃ of-450 ℃ of temperature, add magnetic-field annealing, two end faces of the non-crystaline amorphous metal cylinder after the annealing are the coated glue special equably, with 2 or 2 above non-crystaline amorphous metal cylinders composition iron core column that is stacked.
Make upper yoke 4 and lower yoke 5, the available amorphous alloy strip material that waits width that adheres to specification is wound on the pellet of cylindrical shape, makes the width of upper yoke 4 and lower yoke 5 annulus all equal the diameter of iron core column; Upper and lower iron yoke 4,5 after the winding also need be handled through adding the magnetic field vacuum annealing, thereby eliminates internal stress, reduces iron loss.
