Abstract
The utility model discloses an amorphous alloy iron core with a circular section, which belongs to the technical field of magnetic electronic parts and components and comprises a winding inner frame and an amorphous alloy iron core arranged inside the winding inner frame and further comprises interlayer partition boards. The section of the winding inner frame is circular or oval, adjacent layers in vertical direction are separated through the interlayer partition boards, a layer of epoxy coating is covered on a lamination sheet set, and the thickness of the epoxy coating is smaller than 1 mm. The amorphous alloy iron core has the advantages of being simple in structure, improving performance, improving production efficiency and reducing cost compared with the prior art by means of the structure.
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; So 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, said amorphous alloy iron core is divided into several layers, adjacent separates through the interlayer dividing plate between two-layer up and down; Every layer amorphous alloy iron core is made up of the laminate patch group and the width of every one on top of another group all equates; The thickness of this laminate patch group increases progressively 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 said laminate patch group, the thickness of epoxy coating is less than 1mm.
The thickness of said epoxy coating is preferably 0.4-0.7mm.
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.
Description of drawings
Accompanying drawing is the structural representation of a kind of 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, and the cross section of said winding inside casing skeleton 1 is oval; Reach all symmetrical up and down about the cross section of said amorphous alloy iron core 2; And be notch cuttype, adjacent separate 3 through the interlayer dividing plate between two-layer up and down, every layer amorphous alloy iron core 2 is made up of laminate patch group 4 and the width of every one on top of another group 4 all equates; The thickness of this laminate patch group 4 increases progressively to form notch cuttype from the centre to both sides; 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 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 0.4mm.
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.
