Abstract
The utility model discloses a novel amorphous alloy core with a circular section, belonging to the technical field of a magnetic electronic component. The amorphous alloy core comprises a winding inner-frame skeleton and an amorphous alloy core positioned in the winding inner-frame skeleton, and further comprises an interlayer partition, wherein the section of the winding inner-frame skeleton is circular or elliptical; the section of the amorphous alloy core is symmetrical both bilaterally and longitudinally and is step-shaped; the amorphous alloy core is divided into an upper layer and a lower layer which are symmetrical; the two layers are separated by the interlayer partition; the amorphous alloy core on each layer is composed of a plurality of lamination groups; and the lamination groups are covered with an epoxy coating with a thickness less than 1 mm. With the aforesaid structure, the novel amorphous alloy core with the circular section disclosed by the utility model is simple is structure, improved in performance, increased in production efficiency and reduced in cost in comparison with the prior art.
Description
Technical field
The utility model relates to magnetic electron components and parts technical field, particularly relates to a kind of circular section amorphous alloy iron core.
Background technology
In recent years; China's amorphous alloy transformer development rapidly; It is widely used in fields such as distribution, wind-powered electricity generation, solar power generation with superior energy-saving effect, but since the magnetic flux density of amorphous alloy transformer far below the silicon steel sheet transformer, and winding is the reason of rectangular configuration; Its manufacturing cost is high always, on price, is in certain inferior position; Because winding inside casing skeleton is a rectangle, anti-sudden short circuit ability is relatively poor; And amorphous alloy iron core generally all applies the thick epoxy resin of 2mm; Because epoxy coating is thicker, when curable epoxide, is easy to generate stress, and amorphous iron core counter stress is very responsive; Cause the no-load loss and the no-load current of amorphous iron core bigger, influence transformer performance; And thicker epoxy coating has increased curing time, causes production efficiency low, and delivery cycle is long; The epoxy coating that 2mm is thick makes the oversized of iron core, and the cost of corresponding transformer is also higher.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of simple in structure, performance improvement, production efficiency improves, cost reduces circular section amorphous alloy iron core are provided.
The utility model comprises winding inside casing skeleton and is positioned at its amorphous alloy iron core, also comprises the interlayer dividing plate, and the cross section of said winding inside casing skeleton is circular or oval; Reach all symmetrical up and down about the cross section of said amorphous alloy iron core; And be notch cuttype, amorphous alloy iron core is divided into laterally zygomorphic two-layer, separates through the interlayer dividing plate between two-layer; Every layer amorphous alloy iron core is made up of some groups of laminate patch groups; The width of this laminate patch group successively decreases to form notch cuttype from the centre to both sides, and the summit at the outstanding right angle of each ladder links to each other successively and forms a circular arc, and the arc section of the relative position of this circular arc and winding inside casing skeleton is a concentric circles; Be coated with one deck epoxy coating on the laminate patch group, the thickness of said epoxy coating is less than 1mm.
The thickness of said epoxy coating is preferably 0.3-0.7mm; The thickness of said epoxy coating most preferably is 0.6mm.
The utility model compared with prior art has owing to adopt above structure: simple in structure, performance improvement, the advantage that production efficiency improves, cost reduces.

Accompanying drawing is the structural representation of the novel circular section of the utility model amorphous alloy iron core.
Among the figure: 1, winding inside casing skeleton, 2, amorphous alloy iron core, 3, the interlayer dividing plate, 4, the laminate patch group, 5, epoxy coating.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
Shown in accompanying drawing, the amorphous alloy iron core 2 that it comprises winding inside casing skeleton 1 and is positioned at it also comprises interlayer dividing plate 3; The cross section of said winding inside casing skeleton 1 is oval; Reach equal up and down symmetry about the cross section of said amorphous alloy iron core 2, and be notch cuttype, amorphous alloy iron core 2 is divided into laterally zygomorphic two-layer; Separate 3 through the interlayer dividing plate between two-layer; Every layer amorphous alloy iron core 2 is made up of some groups of laminate patch groups 4, and the width of this laminate patch group 4 successively decreases to form notch cuttype from the centre to both sides, and the summit at the outstanding right angle of each ladder links to each other successively and forms a circular arc; The arc section of the relative position of this circular arc and winding inside casing skeleton 1 is a concentric circles, is coated with one deck epoxy coating 5 on the laminate patch group 4; The thickness of said epoxy coating 5 is 0.6mm.
Above-described embodiment is more preferably one of embodiment of the utility model, and common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included within the protection range of the utility model.
