Description
Technical field
The utility model relates to field transformer, is specially a kind of amorphous alloy transformer.
Background technology
Amorphous alloy material is the new magnetic material of coming out nineteen seventies, and it is the alloy of a kind of iron, boron series, and the alloy liquid of fusing is ejected on the low temperature roller of a high speed rotating with 10
6℃/speed of S cools off fast, the alloy material that makes alloy have little time to constitute crystalline solid and form a kind of noncrystal, the magnetic energy of amorphous alloy material is very little, therefore its magnetic hysteresis loss is very low, because the resistivity height of amorphous alloy strips, single-sheet thickness only is 0.02mm, so its eddy current loss is also very little.At present, most of amorphous alloy transformers structurally adopt three-phase five-limb, in the outside, coil two ends the amorphous iron stem stem are arranged all, in manufacturing process, and complex process, and material consumption is bigger, and weight lays particular stress on.
The utility model content
The purpose of this utility model provides a kind of amorphous alloy transformer, adopts the three-phase three-limb structure, to change the high problem of complex manufacturing, production cost that traditional amorphous alloy transformer three-phase five-limb structure is brought.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of amorphous alloy transformer, include iron core and the coil that is wrapped on the iron core, it is characterized in that: described iron core comprises the outer iron core of frame shape and the interior iron core of a plurality of frame shapes, described interior iron core is arranged side by side and the frame wall fits successively, described outer iron core surrounds described interior iron core, and the frame inwall of outer iron core and described interior iron core outermost end frame wall in a row fit; On the frame wall that interior iron core is fitted mutually, be wound with coil respectively on outer iron core and the interior iron core frame wall of fitting.
Described a kind of amorphous alloy transformer, it is characterized in that: iron core and outer iron core twine by a plurality of non-crystaline amorphous metal bar bending back stacks and constitute rectangular box-like iron core in described, be bonded with each other after the bending of non-crystaline amorphous metal bar two ends, the seam crossing after the bending of non-crystaline amorphous metal bar two ends accompanies rubber slab.
Described a kind of amorphous alloy transformer is characterized in that: iron core has two in described, and a frame wall of interior iron core is fitted mutually, and another frame wall is fitted with described outer iron core frame inwall respectively, constitutes the three-phase three-column iron core; Described coil is square, and the coil on the sidewall that wherein interior iron core is fitted is mutually formed by the Copper Foil coiling, and the coil on the sidewall that interior iron core and outer iron core are fitted mutually is flat around forming by the copper conductor layering.
Described a kind of amorphous alloy transformer is characterized in that: between outer iron core seam crossing and the interior iron core space is arranged, be lined with the chock piece in the described space.
In the utility model, iron core is a rectangle frame iron core of reeling and forming with many non-crystaline amorphous metal bar stacks, three iron cores like this (two little one is big) are arranged in one, two little rectangles are arranged side by side, the large rectangle iron core is enclosed in the side by side little iron core outside, form three-phase three-column two frame iron cores, compare with traditional three-phase five-limb, reduced seam, and seam is stepping overlap joint shape along yoke is uniform down, seam crossing pad rubber slab, and elasticity clamps, make transformer noload losses and no-load current all have in various degree and reduce that performance improvement is apparent in view.Coil on the sidewall that interior iron core and outer iron core are fitted mutually is a high-tension coil, uses the oxygen-free cupreous coiling; Coil on the sidewall that interior iron core is fitted mutually is a low-voltage coil, by the Copper Foil coiling; Coil is square structure, does not have helical angle, and vertically electric capacity is bigger, and Short Circuit withstand, lightning impulse resistant ability are strong.The utility model coil support iron core owing to there is not the iron core side column at two ends, shortens the device body relatively, has significantly reduced and has used material.Seam crossing pad rubber slab, elasticity clamps, and reduces noise.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is made iron core than original amorphous alloy strips, and no-load loss reduces by 5～10%, and no-load current reduces by 10～20%, and has reduced material in a large number, and energy-saving effect is fine.
2, the utility model low-voltage coil Copper Foil coiling, high-tension coil is led the flat coiled square structure of layering with copper, and helical angle thereby end cross stray field are very not little owing to having, has the stronger short-circuit capacity that bears, and the vertical electric capacity of high pressure is bigger, and lightning impulse voltage is evenly distributed, strong shock resistance.
3, the utility model has reduced seam, the chock piece reduces gaping of joints on gap pad between the seam crossing of outer iron core and the interior iron core, but and sound insulation after seam crossing adds rubber slab and clamps, eliminate vibrations, reduce noise, the utility model product and existing product noise are obviously reduced.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.A kind of amorphous alloy transformer, include iron core and the coil that is wrapped on the iron core, iron core comprises a rectangular box-like outer iron core 1 and two rectangular box-like interior iron cores 2,3, interior iron core 2,3 and outer iron core 1 twine by a plurality of non-crystaline amorphous metal bar bending back stacks and constitute rectangular box-like iron core, be bonded with each other after the bending of non-crystaline amorphous metal bar two ends, seam crossing 4,5,6 after the bending of non-crystaline amorphous metal bar two ends accompanies rubber slab, between outer iron core seam crossing 4 and the interior iron core 2,3 space is arranged, be lined with the chock piece in the space.A frame wall of interior iron core 2,3 is fitted mutually, and another frame wall is fitted with outer iron core 1 frame inwall respectively, constitutes the three-phase three-column iron core; Coil 7,8,9 is square, and the coil 7 on the sidewalls that wherein interior iron core 2,3 is fitted is mutually formed by the Copper Foil coiling, is low-voltage coil; Coil 8,9 on the sidewall that interior iron core 2,3 and outer iron core 1 are fitted mutually is flat around forming by the copper conductor layering, is high-tension coil.
