Description
Technical field
The present invention relates to the core construction of amorphous alloy transformer.
Background technology
Amorphous alloy transformer is a kind of low-loss energy-economic transformer of excellence, and it utilizes amorphous alloy material to replace silicon steel sheet to make iron core, and its feature is that no-load loss is low and no-load current is little, has therefore obtained increasing attention.Amorphous alloy core all is to be reeled by amorphous alloy strips to form, but the present main dependence on import of amorphous alloy strips, the specification of strip width size seldom, therefore existing amorphous alloy transformer iron core all is the square-section, can not be circular or polygonal cross section.Because the girth minimum of circle in the sectional area shape selects for use the iron core of square-section will grow with respect to the winding coil average turn length that adopts circular core section, not only wastes copper, also increases the load loss of meeting transformer.The amorphous core of existing square-section has determined that also the winding coil shape can only be a rectangle also, and when transformer was short-circuited, the stressed too late circular winding of rectangle winding was even, bears the short-circuit electromotive force easy deformation.This has further reduced the anti-short circuit capability of amorphous alloy transformer.
The patent of invention of Chinese patent 200610117478.8 has proposed a kind of core construction of three-frame and three pole amorphous alloy transformer, this core construction is by one or more groups unshakable in one's determination composition, and every group of iron core is made up of two little frames iron cores of cover in the big frame iron core.This core construction is one group or the core section of many groups all is rectangle, so just can't avoid square-section corresponding winding coil average turn length unshakable in one's determination length, a series of shortcomings such as anti-short circuit capability difference.The patent No. is that the utility model patent of ZL200620046097.0 has proposed a kind of amorphous alloy roll core construction, this structure is to be put together then by the iron core frame that non-crystaline amorphous metal and two kinds of materials of silicon steel sheet are wound as some different cross sections, and the cross section after the amalgamation becomes sub-circular.In this structure owing to used non-crystaline amorphous metal and two kinds of materials of silicon steel sheet, increased the complexity of manufacturing process greatly, because the core section shape that silicon steel sheet is reeled in this structure all is in order to remedy the edge shape of approximate circle, therefore the shape kind of making an amalgamation needed silicon steel sheet wound core unshakable in one's determination is a lot, complex process, actual operability difficulty is big.Owing to an amorphous alloy material coiled master frame in this structure, it is low to account for proportion unshakable in one's determination again, and therefore this core construction is little with regard to largely having weakened the no-load current that amorphous alloy core had, the advantage that no-load loss is low.
Summary of the invention
The object of the invention mainly is the shortcoming that overcomes existing amorphous alloy transformer square-section iron core, improves the amorphous alloy transformer iron core performance, economical with materials, and the anti-short circuit capability of raising transformer proposes a kind of core construction of being reeled by single amorphous alloy material.
Amorphous alloy core structure of the present invention is a kind of conglobate core construction in cross section of being reeled by amorphous alloy strips.Permeability magnetic material has only non-crystaline amorphous metal a kind of in this structure, and the width of amorphous alloy strips can be one or more, so manufacturing process is simple relatively, can give full play to the advantage of amorphous alloy core.And core limb of the present invention cross section is circular, has saved the material of winding coil, improves the anti-short circuit capability of amorphous alloy transformer.
The technical scheme that technical solution problem of the present invention adopts is: iron core of the present invention is made up of the amalgamation unshakable in one's determination of the single frame amorphous alloy roll of several different cross section shapes, the iron core frame both sides of amalgamation are filled by molding for epoxy resin spare, make core section after the final combination for circular.
In the core construction of the present invention, several single frame amorphous alloy roll iron cores can be formed by the amorphous alloy strips coiling of same widths, also can select the amorphous alloy strips of different in width.
In the described core construction, the middle part of core section is main frame, identical by four strip width, the non-crystaline amorphous metal single frame that lap wound thickness is identical is unshakable in one's determination to be constituted, main frame is divided into inside and outside two-layer, main frame both sides respectively have a lap wound thickness to be different from the secondary frame of single frame formation unshakable in one's determination of main frame, these two single frame iron cores can be selected the band with main frame same widths for use, also can select and main frame strip material with different width, rolling up lap wound thickness unshakable in one's determination as two single frames of secondary frame is to determine according to the lap wound thickness of main frame, make the core section that finally makes after the combination for circular, the core section after the final combination and the circular part that differs are filled the epoxy resins insulation molded part of respective shapes by secondary frame both sides.
In the above-mentioned core construction, several single frame amorphous alloy rolls iron cores and insulation molding part fit tightly fixing mutually, and amalgamation forms unshakable in one's determination whole.
In the above-mentioned core construction, if the single frame amorphous alloy roll of several mutual amalgamations iron core is the single frame of remaining silent, the iron core after the amalgamation just is the volume iron core of remaining silent; If the single frame amorphous alloy roll iron core of several mutual amalgamations is the opening single frame, the iron core after the amalgamation is just unshakable in one's determination for the opening volume.
In the above-mentioned core construction, the amorphous alloy roll that pieces together mutually is unshakable in one's determination for single-phase volume is unshakable in one's determination, the three-phase three-column volume is unshakable in one's determination or the three-phase and five-pole volume is unshakable in one's determination.
With respect to existing amorphous alloy core, the cross section of core construction of the present invention is circular, makes long reduction of average turn of coil, has saved copper material.Because permeability magnetic material has only non-crystaline amorphous metal a kind of in the core construction of the present invention, the width of amorphous alloy strips can be selected combination in existing bandwidth, so manufacturing process is simple relatively, can give full play to the low advantage of amorphous alloy core no-load loss.Core construction of the present invention also makes corresponding winding coil can be circle, has improved the anti-short circuit capability of amorphous alloy transformer.In addition,, do not need to carry out iron core and seal, add and comprise the part epoxy molded part in this core construction, therefore improved the reliability of intensity unshakable in one's determination and transformer work because that this structure can be made the volume of remaining silent is unshakable in one's determination.
