The cross section of the iron core is changed to be circular, so that the length of a conducting wire of a winding can be reduced, the cost of a conducting wire of a transformer can be reduced, the strength of an inner frame of the winding can be effectively strengthened, and the sudden short circuit resistance of the transformer can be strengthened.
Description
Technical field
The utility model relates to field transformer, relates in particular to a kind of circular section amorphous alloy cored 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 purpose of this utility model is to overcome the defective of prior art and a kind of circular section amorphous alloy cored 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 cored structure, comprise winding inside casing skeleton and the amorphous alloy iron core that is positioned at it, and also comprise the interlayer dividing plate, wherein,
The cross section of described winding inside casing skeleton is circular or oval;
Equal symmetry about the cross section of described amorphous alloy iron core and up and down, and be notch cuttype, described amorphous alloy iron 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 iron core is made 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 described winding inside casing skeleton is a concentric circles.
Above-mentioned circular section amorphous alloy cored structure, wherein, the thickness of described laminate patch group successively decreases to both sides from the centre.
The beneficial effects of the utility model are: 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.
Description of drawings
Fig. 1 is the structural representation of circular section of the present utility model amorphous alloy cored structure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, there is shown a kind of circular section of the present utility model amorphous alloy cored structure, comprise winding inside casing skeleton 1 and the amorphous alloy iron core 2 that is positioned at it, also comprise interlayer dividing plate 3, wherein:
The cross section of winding inside casing skeleton 1 is circular or oval;
Equal symmetry about the cross section of amorphous alloy iron core 2 and up and down, and be notch cuttype, amorphous alloy iron core 2 is divided into two-layer to what become up and down, separate by interlayer dividing plate 3 between two-layer, every layer amorphous alloy iron core 2 is made of some groups of laminate patch groups 21, the width a of this laminate patch group 21 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, the arc section of the relative position of this circular arc and winding inside casing skeleton 1 is a concentric circles, after left and right sides two halves amorphous alloy iron core 2 was fastened respectively, amorphous alloy iron core 2 cross sections in the whole winding inside casing skeleton 1 totally were circle or ellipsoidal structure.The thickness b of laminate patch group 21 successively decreases to both sides from the centre.
This embodiment is by the width of change laminate patch group 21, in conjunction with different layouts, makes the cross section of amorphous alloy iron core 2 be notch cuttype, and the cross section of winding inside casing skeleton 1 is circular or oval.
In sum, the utility model changes circle by the cross section with amorphous alloy iron core 2 into by rectangle, having overcome present amorphous alloy transformer core cross section is rectangular in form, so the winding inside casing is a rectangular in form, when being subjected to low pressure short circuit in winding electric power and tightening up the center intensity on inside casing four limits a little less than, anti-sudden short circuit ability is failed shortcoming fully up to expectations.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
