Abstract
The invention relates to three-phase transformer iron-core, for concreteness that is the stereo three-phase transformer with three identical single phase iron-cores coiled by silicon steel belt, the three iron-core columns are combined together to a equilateral triangle with circular intersecting surface. The transformer made by said iron-core has small magnetic resistance,less iron loss and low noise.
Description
Invention relates to the three-phase transformer iron core, and specifically a kind of three identical single-phase iron cores that formed by continuous silicon strip coiling are bolted together and form the rounded three phase transformer iron core of a kind of iron core column cross section.
Existing three transformer cores are divided into blade inserting and takeup type two big classes.The iron core column of blade inserting three-phase transformer iron core and iron yoke are by being cut into different in width, the horizontal stripe of different single piece of silicon steel band and vertical bar inlay repeatedly that dress forms, therefore between the iron core column of whole three-phase transformer core and the iron yoke many slits are arranged, the transformer core magnetic loop is interrupted discontinuous, cause the magnetic resistance of iron core to increase, the no-load loss of transformer and no-load current increase, and are easy to generate leakage field and noise.
The takeup type iron core has overcome the above-mentioned shortcoming of blade inserting iron core, has significantly reduced magnetic resistance, has reduced the loss of iron core.But its three iron core column are in a plane.Obviously, the shortcoming of the iron core of this structure is the magnetic loop imbalance, and the magnetic loop of A phase, C phase is long, and the magnetic loop of B phase is shorter, can cause three-phase current unbalance like this.Therefore this planar structure is not desirable structure, is further improved.
The objective of the invention is to design a kind of cubic three phase transformer iron core with round section, the three-phase magnetic loop of this iron core is equal fully, and the shortest, so that further reduce the no-load current and the no-load loss of iron core, alleviates the weight of iron core, saves material.
Its main technical schemes is:
Use earlier the curve cutting machine, by specific Mathematical Modeling, steel tape is carried out curve open material, to open the continuous core roll coil of strip coiled iron core column and the iron yoke cross section that obtain behind the material with up-coiler then and be semicircular single-phase iron core, three single-phase iron cores are assembled into three-dimensional three-phase transformer iron core, three iron core column of this three phase transformer iron core are assembled in twos by the iron core column of three single-phase iron cores, and its cross section is circular.And the center of circle of these three iron core column circular cross sections constitutes an equilateral triangle.All by the center of this equilateral triangle, the surface of the diameter of the semi-circular cross-section of the iron core column of single-phase iron core and coiling core band constitutes 60 degree angles to the extended line of the diameter of the iron core column semi-circular cross-sections of each single-phase iron core.
Advantage of the present invention is:
Because iron core is reeled with continuous silicon strip and formed, and does not cut, leakage field has fundamentally been eliminated in no seam and gap, has reduced magnetic resistance, has reduced iron loss and noise.
Iron core column cross section of the present invention is rounded, and its iron space factor is the highest, is other square cross section iron core, and multistage notch cuttype cross section iron core is incomparable.
Three-phase magnetic loop of the present invention is equal fully, all symmetry.This has overcome the shortcoming of iron core in the past because of the unequal caused three-phase current unbalance of magnetic loop.
Can be made into oil-immersed power transformer with the present invention, dry-type power transformer and various electronic transformer, they all have little, in light weight, a series of outstanding advantages such as loss is low, three-phase balance of volume.It is the ideal product that power industry and electron trade update.

Fig. 5 is original plane circular section iron core.
As shown in the figure: tri-phase iron core is made of 3 single-phase iron cores, each single-phase iron core is by on the half round post, lower yoke 3,2 with semi-cylindrical left and right sides iron core column constitute a rectangle, 3 iron core column 1 of tri-phase iron core are made of the iron core column of two single-phase iron cores respectively, the iron core column cross section of each tri-phase iron core is rounded, the circular line of centres of the cross section of 3 iron core column of tri-phase iron core constitutes an equilateral triangle ABC, the extended line of the semicircle diameter of the cross section of the iron core column of each single-phase iron core is the center O by equilateral triangle ABC all, and is 60 with the plane of its coiling steel band and spends angles.
