Abstract
The utility model discloses an amorphous alloy three-dimensional iron core, which comprises three iron core bodies. The amorphous alloy three-dimensional iron core is characterized in that the three iron core bodies form a three-dimensional structure and respectively consist of a template, an iron core and an inner mold; the template is divided into an outer template and an inner template; the iron core is positioned inside the outer template; the inner template is arranged in the middle of the iron core; the inner mold is arranged in the inner template; and the outer template binds and molds the whole amorphous iron core through a steel tape. The amorphous alloy three-dimensional iron core provided by the utility model has the advantages that under the design conditions of the same iron core magnetic density, coil turns and wire specification, the quantity of circular coils which are wound around the amorphous alloy three-dimensional iron core accounts for 91 percent of that of square coils which are wound around an amorphous alloy single-bandwidth iron core, 9 percent of materials is saved, and the materials are effectively saved. Moreover, under the conditions of the same diameter, center distance and window height, compared with an amorphous alloy plane ladder type iron core, the amorphous alloy three-dimensional iron core has the advantage that about 10 percent of materials is saved.
Description
Technical field
The utility model relates to the manufacturing technology field of amorphous alloy iron core, and a kind of stereo amorphous alloy is three-dimensional unshakable in one's determination specifically.
Background technology
Amorphous alloy distribution transformer is a kind of energy-saving controller switching equipment that adopts new material, new construction, new technology, and its core material is a kind of non-crystaline amorphous metal, compares with the traditional silicon iron and steel heart, has outstanding low no-load loss characteristic.Existing amorphous alloy transformer core folds rear extrusion modling by some groups of amorphous alloy strips, for guaranteeing that amorphous alloy strips in the amorphous alloy transformer core can be not loose and break away from, amorphous alloy transformer core adopts 0.3 millimeter silicon steel sheet parcel usually inside and outside iron core, adopt coating adhesive on the end face of lap seam of amorphous alloy strips or epoxy resin is cured, seals and insulate and have on the iron core.Said structure is the single band core construction of non-crystaline amorphous metal, so-called single band iron core exactly can only be with a kind of iron core of doing in 142mm or 170mm or three kinds of bands of 213mm, it also can be two-layer, equal 2*142mm or 2*170mm or 2*213mm, like this so that coil is a square structure, square coil is many with material, the strength of sudden short circuit does not have being evenly distributed on circular coil in the distribution of square coil on the other hand, be that anti-short circuit capability is relatively poor, single band bottom unshakable in one's determination all is provided with the overlap joint mouth in addition, the exciting curent and the noise that produce are larger, bring pollution to surrounding environment.
Summary of the invention
In order to solve the deficiencies in the prior art, provide a kind of coil few with material, province unshakable in one's determination material, the three-dimensional iron core of stereo amorphous alloy that noise is little.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of stereo amorphous alloy is three-dimensional unshakable in one's determination, comprise three iron cores, it is characterized in that: described three iron cores mix into the stereoscopic three-dimensional structure, and iron core is comprised of template, iron core, internal mold mold, and template is divided into exterior sheathing and inner formword, iron core is positioned at the exterior sheathing inboard, is provided with inner formword in the middle of unshakable in one's determination, the internal mold mold is installed in the inner formword, exterior sheathing by steel band with whole amorphous core colligation moulding.
Described exterior sheathing is isosceles-trapezium-shaped, three onesize iron core waists is connected mix into a stereoscopic three-dimensional iron core, consists of core limb after adjacent two iron core waists connect, and the cross section of core limb is the circle that two semicircle forms.
The beneficial effects of the utility model are:
1, under close, the coil turn of equal magnetic unshakable in one's determination, the design condition with the wire gauge lattice, around stereo amorphous alloy three-dimensional unshakable in one's determination around circular coil only account for around 91% of the square coil of the single bandwidth iron core of non-crystaline amorphous metal with material, economize on material 9%;
2, the three-dimensional bottom unshakable in one's determination of stereo amorphous alloy is that the structure of remaining silent does not overlap mouth, and the exciting curent of generation is little, so noise is little;
3, under diameter, centre-to-centre spacing, the high identical condition of window, the three-dimensional iron core of stereo amorphous alloy is economized material about 10% than amorphous alloy plane stepped iron core.
