Abstract
A kind of amorphous alloy stereo roll iron core suitable for three-phase transformer, it is characterised in that：It is to roll up iron heart body by three cylindrical solids that the type amorphous alloy wound core frame spelling of the identical frame column cross section semicircular in shape being wound into using amorphous alloy strips of three structures and arc surface indention is formed.Since the three-phase magnetic circuit of the utility model is full symmetric, iron core seamless, the magnetic line of force can be linked up freely between different core limb frames, make core limb magnetic flux density relatively uniform, no-load current, no-load loss and the noise of transformer can be substantially reduced, it simplifies iron core and grips process, the ability of the impact resistance of enhancing transformer, vibration resistance and resistance to shorting.Small product size is small, and noise is small, energy conservation and environmental protection.
Description
Technical field
The utility model is related to a kind of transformers, particularly relate to a kind of non-crystaline amorphous metal suitable for three-phase transformer and stand
Body rewinding material.
Background technology
Non-crystaline amorphous metal magnetic property is especially good, and eddy-current loss substantially reduces, specific loss be only silicon steel sheet 20% ~
30%, but its physical property of this band is especially hard, and hardness is five times of silicon steel sheet, is not easy to cut, processing difficulties.Therefore it is public
Know the non-crystaline amorphous metal Core Structure in Three-Phase Transformers of technology（As shown in Figure 1）Five column of mostly four frame breaks yoke formula planar structure, coil
For rectangle, assembled using the mode of being inserted in.Caused by structure, technique due to the above-mentioned prior art, there is three-phase magnetic circuits
The shortcoming that the magnetic line of force cannot link up between unbalanced, main flux circuit seam, frame, overall magnetic resistance is big, while iron core frame
Grip very difficult, cumbersome.
Invention content
The purpose of this utility model in place of overcome the deficiencies in the prior art precisely in order to provide a kind of suitable for three phase transformations
The amorphous alloy stereo roll iron core of depressor.
The purpose of this utility model can be realized by following technique measures：
The amorphous alloy stereo roll iron core suitable for three-phase transformer of the utility model is adopted by three structures are identical
The frame column cross section semicircular in shape and the type amorphous alloy wound core frame group of arc surface indention being wound into amorphous alloy strips
Spell the three cylindrical solids volume iron heart body formed.
Frame structure of type amorphous alloy wound core frame described in the utility model for rectangular configuration, the circle of indention structure
Cambered surface is to be wound to be formed by the amorphous alloy strips of different size formed using laser cutting；Three cylindrical solid rolls up iron
Heart body is cured through epoxy resin dipping drying.
The utility model gives full play to the advantage of its magnetic property, and using laser cutting technique, amorphous alloy strips are cut
Required width is cut into, the technical barrier for solving amorphous alloy strips cutting by the band of different in width, is wound into semicircle
Then three attached column frames are assembled into three dimensional wound core body, and impregnate and dry through epoxy resin cure by saw-tooth shaped cross section rewinding material frame
Dry, with wound core transformer coil winding device coiling, final assembly is into amorphous alloy stereo roll iron core three-phase transformer.
The utility model has the advantages that compared with prior art：
1st, no-load loss and no-load current decline to a great extent：Transformer core no-load loss is in similary magnetic flux density and material
Under, it is directly proportional to iron core weight.Due to the utility model frame fewer than four frame pentastyle of existing scheme, iron core weight is reduced
A quarter, no-load loss will decline 25%；Due to iron core seamless, the magnetic line of force can communicate with each other between frame, and magnetic resistance subtracts significantly
Small, no-load current will also decline to a great extent, and give full play to the optimal magnetic property of amorphous alloy strips and best three dimensional wound core knot
The advantage of structure has good energy-saving effect.
2nd, raw material are saved, reduce cost：Existing amorphous alloy transformer iron core breaks yoke formula structure for four frames, five column, this reality
With it is novel be three frame three dimensional wound core structures, save core material a quarter, while manufacturing process is simple and direct, saves manpower, drop
Low cost.
3rd, due to the cured dipping drying of three rewinding material frames, a secured entirety is combined into, it is resistance to substantially increase transformer
Shock and vibration and anti-short circuit capability, small, noise is small, energy conservation and environmental protection.

Specific embodiment
The utility model is below with reference to embodiment（Attached drawing）It is further described：
As shown in Figure 2,3, the amorphous alloy stereo roll iron core suitable for three-phase transformer of the utility model is by three
The amorphous of the identical frame column cross section semicircular in shape being wound into using amorphous alloy strips of structure and arc surface indention is closed
The three cylindrical solids volume iron heart body 1 that golden 2 spelling of rewinding material frame forms；Three cylindrical solid rolls up iron heart body through epoxy resin
Dipping drying is cured.
The type amorphous alloy wound core frame as described in the utility model of Fig. 4,5,6 is the frame structure of rectangular configuration, in sawtooth
The arc surface of shape structure is to be wound to be formed by the amorphous alloy strips of different size formed using laser cutting.
The utility model gives full play to the advantage of its magnetic property, and using laser cutting technique, amorphous alloy strips are cut
Required width is cut into, the technical barrier for solving amorphous alloy strips cutting by the band of different in width, is wound into semicircle
Then three attached column frames are assembled into three dimensional wound core body, and impregnate and dry through epoxy resin cure by saw-tooth shaped cross section rewinding material frame
Dry, with wound core transformer coil winding device coiling, final assembly is into amorphous alloy stereo roll iron core three-phase transformer.
