Abstract
The invention discloses a circular-section amorphous alloy iron-core structure. The structure comprises a winding inner frame skeleton and an amorphous alloy iron-core positioned in the winding inner frame skeleton, wherein the section of the winding inner frame skeleton is round or oval; the section of the amorphous alloy iron-core is symmetrical in both transverse direction and longitudinal direction and is in a stepped shape; a circular arc is formed by connecting the vertexes of the convex right-angles of each of steps in turn; and the circular arc and an circular arc segment at opposite positions of the winding inner frame skeleton are on concentric circles. In the structure, the section of the iron-core is changed into a circle, which can reduce the length of a lead wire of a winding, reduce the lead wire cost of a transformer, effectively enhance the strength of a winding inner frame, and enhance the sudden short-circuit performance resistance of the transformer.
Description
Technical field
The present invention relates to field transformer, relate in particular to a kind of circular section amorphous alloy core structure.
Background technology
China's amorphous alloy transformer development in recent years is comparatively rapid, and it is widely used in fields such as distribution, wind-powered electricity generation, solar power generation with superior energy-saving effect.But because the magnetic flux density of amorphous alloy transformer is far below the silicon steel sheet transformer, and winding is the reason of rectangular configuration, so its manufacturing cost is high always, is in certain inferior position on price.Because winding inside casing skeleton is a rectangle, anti-sudden short circuit ability is relatively poor.
For reducing cost, the normal at present method that adopts the copper iron ratio that changes transformer is used iron more, uses copper less.For strengthening the anti-sudden short circuit ability of transformer, present way is to strengthen winding inside casing frame strength, adopts epoxy material inside casing skeleton.
But present this method has following shortcoming: change transformer copper iron than causing transformer loss to increase easily; The epoxy material toughness is relatively poor, and inside casing short-axis direction easy deformation or cracking behind the coil press mounting influence intensity and insulation property, and thickness is thick more, and cost is big more.
Summary of the invention
The objective of the invention is to overcome the defective of prior art and a kind of circular section amorphous alloy core structure is provided, it changes core section into circle, can reduce the conductor length of winding, reduce transformer lead cost, can also effectively strengthen winding inside casing intensity, strengthen the anti-sudden short circuit performance of transformer.
The technical scheme that realizes above-mentioned purpose is: a kind of circular section amorphous alloy core structure, comprise winding inside casing skeleton and the amorphous alloy core that is positioned at it, wherein,
The cross section of described winding inside casing skeleton is circular or oval;
Equal symmetry about the cross section of described amorphous alloy core and up and down, and be notch cuttype, the summit at the outstanding right angle of each ladder linked to each other successively forms a circular arc, and the arc section of the relative position of this circular arc and described winding inside casing skeleton is a concentric circles.
Above-mentioned circular section amorphous alloy core structure, wherein, also comprise the interlayer dividing plate, described amorphous alloy core is divided into two-layer to what become up and down, separate by described interlayer dividing plate between two-layer, every layer amorphous alloy core is made of some groups of laminate patch groups, and the width of this laminate patch group successively decreases 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 described winding inside casing skeleton is a concentric circles.
Above-mentioned circular section amorphous alloy core structure, wherein, the thickness of described laminate patch group successively decreases to both sides from the centre.
Above-mentioned circular section amorphous alloy core structure, wherein, also comprise the interlayer dividing plate, described amorphous alloy core is divided into several layers, adjacent separate by the interlayer dividing plate between two-layer up and down, every layer of amorphous alloy core is made of the laminate patch group and the width of every stacking group all equates, the thickness of this laminate patch group 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 described winding inside casing skeleton is a concentric circles.
Above-mentioned circular section amorphous alloy core structure, wherein, described amorphous alloy core is divided into six layers.
The invention has the beneficial effects as follows: because core section is circle or ellipticity, and because when area is identical, circumference is less than rectangular perimeter, so when iron core was circle or elliptic cross-section, the lead cost was relatively saved; Because the convex surface compressive strength is greater than planar compression intensity, so when winding inside casing skeleton cross section during rounded or circular arc, its anti-sudden short circuit performance will effectively improve.
