Abstract

The invention relates to amorphous double cores with a single coil and an approximate-circle cross-section, comprising two parallel amorphous cores and a coil. The amorphous cores are rectangular rings with four bent corners; the adjacent side limbs of the two amorphous cores form a core limb; and the coil is sheathed on the core limb. The amorphous cores are formed by packing a plurality of amorphous core plates, wherein, the amorphous core plates of one amorphous core have different widths, and the core plates arranged outside are wider than the core plates arranged inside. The two ends of the cross-section of the core limb take the shape which is similar to arc with the middle part raised; and the two ends of the coil respectively take the shape of arc which is similar to the two ends of the core limb. The amorphous double cores of the invention have compact structure, are not only beneficial to saving the usage of copper in the coil but also beneficial to preventing the insulating materials of the coil from being damaged by extrusive corner angles and are mainly used in corresponding amorphous transformers.

Description

Be provided with monocoil cross section approximate circle amorphous two unshakable in one's determination

Technical field

The present invention relates to a kind of monocoil cross section approximate circle amorphous two iron cores that are provided with, belong to technical field of electricity, mainly can be used for various many iron-core transformers.

Technical background

The amorphous core that is used for many iron-core transformers is folded built in together by several layers amorphous core sheet, form the electromagnetic field loop of a closure, be used to transmit magnetic flux, on the core limb of both sides unshakable in one's determination, put coil, produce alternating magnetic field behind the coil electricity, by iron core the magnetic flux in this magnetic field is passed to another coil to form induced current, realize the effect of energy delivery and transformation thus, the width of each layer amorphous core sheet in the present same amorphous core all is identical, the cross section of the side arm unshakable in one's determination of Xing Chenging is rectangular thus, the loop coil that is enclosed within on the core limb also should be rectangular, could adapt with the shape of core limb.Adopt this core construction, the copper consumption of coil is bigger, and the corner angle of corner unshakable in one's determination damage the insulating material on the coil easily.

Summary of the invention

For overcoming the above-mentioned defective of prior art, the invention provides and a kind ofly be provided with monocoil cross section approximate circle amorphous twoly unshakable in one's determination, adopts this combination unshakable in one's determination to help reducing the copper consumption of coil, and be difficult for causing damage to the insulating material of coil because of corner angle unshakable in one's determination.

The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of be provided with monocoil cross section approximate circle amorphous two unshakable in one's determination, comprise two amorphous cores arranged side by side and a coil, described each amorphous core is the straight-flanked ring of four angular distortions, the adjacent side arm of two amorphous cores is formed a core limb, described coil is enclosed within on this core limb, described each amorphous core forms by the folded system of some amorphous core sheets, described some amorphous core sheets of same amorphous core have different width, the width of the amorphous core sheet outside being positioned at is greater than the width that is positioned at inboard amorphous core sheet, the two ends of the cross section of described core limb all are the shape that is similar to arc of intermediate projections, and the two ends of each coil are respectively and the similar arc in described core limb two ends.

The invention has the beneficial effects as follows: because the width of the amorphous core sheet outside being positioned on the same iron core is greater than the width that is positioned at inboard amorphous core sheet, when the adjacent side arm of two iron cores constitutes a core limb, the amorphous core sheet that is positioned at the core limb mid portion is wideer than the amorphous core sheet that is positioned at the core limb side, formed the shape that is similar to circular arc or other arcs of intermediate projections thus at the two ends of core limb cross section, correspondingly, the two ends that are enclosed within the coil on the core limb also are the shape of approximate circular arc or other arcs, therefore under identical area of section, the girth of the coil of this shape is little, help saving the copper consumption of coil, simultaneously, because the edge of existing relatively square-section, the edge of core limb iron core wants much level and smooth, do not have the sort of very outstanding rectangle corner angle, therefore effectively avoided the phenomenon of rectangle corner angle infringement coil insulation material.

Description of drawings

Fig. 2 is a main TV structure schematic diagram of the present invention.

Embodiment

Referring to Fig. 1-2, the invention provides a kind of monocoil cross section approximate circle amorphous two iron cores that are provided with, comprise two amorphous cores arranged side by side 100 and a coil 400, described each amorphous core is the straight-flanked ring of four angular distortions, the adjacent side arm of two amorphous cores is formed a core limb, described coil is enclosed within on this core limb, described each amorphous core forms by the folded system of some amorphous core sheets, described some amorphous core sheets of same amorphous core have different width, the width of the amorphous core sheet outside being positioned at is greater than the width that is positioned at inboard amorphous core sheet, the two ends of the cross section of described core limb all are the shape that is similar to arc of intermediate projections, and the two ends of each coil are respectively and the similar arc in described core limb two ends.

The described amorphous core sheet of same iron core can be divided into some groups, and the width of same group amorphous core sheet equates thus to reduce difficulty of processing as much as possible under the situation that guarantees actual effect.

For example, the amorphous core sheet of described same amorphous core can be divided into three groups, and it is the wideest to be positioned at one group of amorphous core sheet of outermost, and it is the narrowest to be positioned at the most inboard one group of amorphous core sheet.Among the embodiment for example shown in the drawings, amorphous core sheet on the same amorphous core is divided into three groups exactly, amorphous core sheet group on one of them amorphous core indicates with 111,112,113 respectively, and the amorphous core sheet group on another amorphous core indicates with 121,122,126 respectively.

The amorphous core sheet of same amorphous core also can adopt other packet modes, for example is divided into four groups or two groups.When being divided into four groups, some amorphous core sheets of described same amorphous core are divided into four groups, and the amorphous core sheet width of each group reduces from outside to inside successively; When being divided into two groups, the amorphous core sheet width that is positioned at one group in the outside is greater than being positioned at inboard one group amorphous core sheet width.

When number of packet is got over for a long time, the core limb cross-sectional shape is level and smooth more, but processing is trouble more, therefore can be according to the performance requirement of iron core combination, size and process equipment and the many-sided factor of processing quantity unshakable in one's determination, take all factors into consideration the packet mode of lamination, on cost and performance, obtain the balance point an of the best.

Each stand out of organizing between the amorphous core sheet should make that the shape at two ends, core limb cross section is a circular arc or other level and smooth arcs generally.

According to applicant's experiment, this amorphous core structure also helps improves performance unshakable in one's determination, helps reducing sectional area unshakable in one's determination, and then reduces consumption of materials unshakable in one's determination.

This amorphous core can adopt existing mode to make, and the amorphous steel band of employing different in width is sheared out the amorphous core sheet of different in width, can adopt existing various packaged type and joint design.
