Abstract
The utility model provides a three-phase stereoscopic wound core which comprises three same wound core frames. Each two adjacent frames of the three core frames are combined to form a stereoscopic wound core which is in a triangular shape in the overhead view. The three-phase stereoscopic wound core is characterized in that: each of the core frames is formed by an inner winding group whose cross section is a parallelogram and an outer winding group whose cross section is a triangle. Compared with the prior art, the three-phase stereoscopic wound core provided by the utility model has the advantages that: the inner winding group is formed by coiling of silicon steel strips with a same width, thus usage amount of trapezoidal silicon steel strips is reduced, waste of materials is reduced, and manufacturing cost is saved.
Description
Technical field
The utility model relates to a kind of volume core construction that is used for transformer or reactor, relates in particular to three-phase stereo volume core construction.
Background technology
Volume of the prior art is unshakable in one's determination generally to adopt trapezoidal silicon strip to reel in winding process, and the outer rim of the iron core frame that making reels forms approaches circle.Like Chinese patent number is the utility model patent of CN99236753.0; Open day is on September 13rd, 2000; Disclose a kind of takeup type 3 D stereo transformer, its design feature is: by the frame iron core that the different in width permeability magnetic material is reeled and formed, its cross sectional shape is formed a semicircular body by the parallel hypotenuse tee section shape that several tilt 30 degree; Then; The frame iron core of three same sizes is mutually these 60 degree angles is combined into the 3 D stereo iron core, wire-wound is on stem, and whole device body hangs spiral shell by three and defends and connect top board with bottom plate and through insulation pressing is also fastening with high-voltage coil and low-voltage coil volume location up and down.In the technique scheme,, need the silicon strip of a large amount of different in width in order to make stem stem to greatest extent near circular.And for small-sized reactor and transformer, this a large amount of different in width silicon strip can cause the waste of a lot of materials, and cost performance is very low.
The utility model content
The utility model technical problem to be solved is to overcome the deficiency of above-mentioned prior art, provide a kind of can effectively to reduce waste of material, cost-effective three-phase stereo volume unshakable in one's determination.
A kind of three-phase stereo volume according to the utility model provides is unshakable in one's determination; Comprise three identical takeup type iron core frames; The adjacent in twos frame amalgamation of three said iron core frames form one overlook shape triangular in shape three dimensional wound core, each said iron core frame is that inboard coiling group and a cross section of parallelogram is approximately leg-of-mutton outside coiling group and constitutes by a cross section.
A kind of three-phase stereo volume iron core that provides according to the utility model also has following attached technical characterictic:
Said inboard coiling group is reeled by the silicon strip that waits width and is formed.
Said outside coiling group is reeled by trapezoidal banded silicon strip and is formed.
The ratio of the thickness of said inboard coiling group and outside coiling group is 1:1 to 1:2.
The amalgamation face of adjacent said iron core frame is 30 degree with the plane included angle, place of said iron core frame.
A kind of three-phase stereo volume iron core that provides according to the utility model compared with prior art has following advantage: the inboard coiling group unshakable in one's determination of the volume in the utility model is to be reeled by the silicon strip that waits width to form; Thereby reduced the use amount of trapezoidal silicon strip; Reduce the waste of material, saved manufacturing cost.

Embodiment
Referring to Fig. 1 to Fig. 4; A kind of three-phase stereo volume according to the utility model provides is unshakable in one's determination; Comprise three identical takeup type iron core frames 1; The adjacent in twos frame amalgamation of three said iron core frames 1 form one overlook shape triangular in shape three dimensional wound core, each said iron core frame 1 is that inboard coiling group 11 and a cross section of parallelogram is approximately leg-of-mutton outside coiling group 12 and constitutes by a cross section.Here alleged be approximately whole outer contour that leg-of-mutton outside coiling group is meant outside coiling group near triangle, for example as can be seen from Figure 4, a leg-of-mutton angle is to be made up of narrower silicon strip.The utility model adopts said structure, can effectively reduce the use of trapezoidal silicon strip, thereby reduce the waste material that trapezoidal silicon strip cutting is caused in actual production, has saved production cost.
Referring to Fig. 3 and Fig. 4, in the foregoing description that the utility model provides, said inboard coiling group 11 is reeled by the silicon strip that waits width and is formed.The silicon strip of width such as employing not only can effectively reduce the generation of waste material, but also has improved production efficiency.
Referring to Fig. 3 and Fig. 4, in the foregoing description that the utility model provides, said outside coiling group 12 is reeled by trapezoidal banded silicon strip and is formed.This structure can guarantee that the coiling group that forms after silicon strip is reeled is the approximate trapezoid structure, dwindles the volume of iron core frame.
Referring to Fig. 3 and Fig. 4, in the foregoing description that the utility model provides, the amalgamation face of adjacent said iron core frame 1 is 30 degree with the plane included angle, place of said iron core frame 1.Above-mentioned angle guarantees to constitute an equilateral triangle structure after the iron core frame amalgamation.
