Description
Technical field
It the utility model is related to transformer technology field, and in particular to a kind of amorphous alloy roll-core.
Background technology
The material for making transformer core at present mainly has two kinds of silicon strip and non-crystaline amorphous metal, non-crystaline amorphous metal and silicon strip phase
Than being a kind of material of more energy efficient manufacture transformer core.Because amorphous alloy material is beneficial to be magnetized and degaussing, this material
For transformer core, transformer magnetic history is very easy to, so as to reduce the open circuit loss of transformer significantly.However,
Amorphous alloy strip material is than 5 times that silicon strip much thinner, much more brittle, and hardness are almost silicon strip, therefore non-crystaline amorphous metal is processed
It is difficult.
The iron core shape of cross section that existing non-crystaline amorphous metal is made is mostly rectangle, therefore coil shape also can only be rectangle,
And can not be it is circular, can not ribbon core coiling, therefore iron core can only make open type iron core, and can not be closed type iron core, open
In closure, amorphous alloy material is bent oral area position amorphous alloy material, and amorphous alloy material surface easily comes off, and is produced
Fish scale-like thing, these tablets float easily causes transformer fault in transformer oil, declines the security of transformer.
No. 200610116272.3 patents of invention of its Patent disclose a kind of amorphous alloy roll-core, it is characterised in that：
The volume iron core is to wind the single frame formed by several different cross section shapes to be put together, and core section shape is in after making split
Predetermined quasi-circular, quasi- polygon or complex, again：The volume iron core uses amorphous alloy material or non-crystaline amorphous metal and silicon strip two
Kind material is made.In several single frames, using section the maximum as main frame, the main frame is continuously wound by the straight strip of non-crystaline amorphous metal
Form, remaining single frame is that continuously winding forms by silicon strip of different shapes.But non-crystaline amorphous metal accounts for whole volume iron in the patent
The possession ratio of core cannot improve, and can not prevent fish scale-like thing caused by amorphous alloy material and shed into transformer
It is interior.
The content of the invention
For the problems of in the prior art, a kind of amorphous alloy roll-core provided by the utility model can be effective
The possession ratio that non-crystaline amorphous metal accounts for whole volume iron core is improved, can effectively prevent amorphous alloy strip because of fish scale-like thing caused by bending
Depart from, improve the reliability of transformer work.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of amorphous alloy roll-core, including iron yoke and three stems, the iron yoke and three stems by three sizes with
The identical single frame of shape is put together, the single frame surface wrap matcoveredn, and the single frame is by some grades of unit frame groups
Into, the unit frame is entwined by amorphous alloy strip, for wind unit frames at different levels amorphous alloy strip width by centre
It is gradually reduced to both sides, the chopped-off head for forming the unit frame of the single frame is set to support bar with final stage.
Preferably, each single frame is made up of 10-20 level unit frame splits.
Preferably, the protective layer is set to silicon strip.
Preferably, the support bar is set to silicon steel bar, and the section of the silicon steel bar is circular arc, is contacted with the silicon strip
Area is big, uniform force, amorphous alloy strip is closely connected.
The beneficial effects of the utility model are shown：
1st, iron core is rolled up in the utility model to be entwined by some grades of amorphous alloy strips and silicon steel bar, can effectively improve amorphous
Alloy accounts for the possession ratio of whole volume iron core, and the use of silicon steel bar adds the structural strength of volume iron core so that non-crystaline amorphous metal is stood
Body volume iron core noise caused by itself stress is greatly lowered；
2nd, single frame surface wrap has silicon strip both can be completely embedded unit frame in the utility model, improves iron core sheet
The bulk strength of body, reduce noise, fish scale-like thing caused by amorphous alloy strip can be prevented completely again and entered in transformer, carried
The high reliability of transformer work.

Embodiment
For the ease of it will be appreciated by those skilled in the art that being further described below in conjunction with the accompanying drawings to the utility model.
A kind of amorphous alloy roll-core as Figure 1-4, including iron yoke 1 and three stems 2, the iron yoke 1 and three
Stem 2 is put together by the identical single frame 3 of three size and shapes, the surface wrap matcoveredn of single frame 3, the list
Frame 3 is made up of some grades of unit frames 301, and the unit frame 301 is entwined by amorphous alloy strip, for winding the lists at different levels
The width of the amorphous alloy strip of first frame 301 is gradually reduced from centre to both sides, forms the unit frame 301 of the single frame 3
Chopped-off head is set to support bar with final stage.
Each single frame 3 is made up of the split of unit frame 301 of 10-20 levels in the utility model, by multistage by non-
The unit frame 301 that peritectic alloy band is wound forms the single frame 3, for winding the amorphous of the unit frames 301 at different levels
The width of alloy strip is gradually reduced from centre to both sides, the section of unit frame 301 is formed polygon, the unit frame 301
Series is more, and the section of unit frame 301 is closer to circle, in the case that the area of section of unit frame 301 is equal, the core
The copper cash that post 2 is wound is fewer, is advantageous to mitigate the heavy burden of volume iron core itself, if the series of unit frame 301 is excessive, causes to roll up
Iron core itself is overweight, influences using effect；The chopped-off head and final stage for forming the unit frame 301 of the single frame 3 are wound with one
Bar support bar, the support bar are set to silicon steel bar 303, as the skeleton of the multistage unit frame 301 of split, improve the list
The bulk strength of frame 3 so that stereo amorphous alloy wound iron core noise caused by itself stress is greatly lowered；The single frame 3
Surface wrap matcoveredn, the protective layer are set to silicon strip 302, and single frame 3 described in the tight of silicon strip 302 can be complete
Prevent fish scale-like thing caused by non-crystaline amorphous metal entirely to enter in transformer, while the section of the silicon steel bar 303 is circular arc, with
The contact area of silicon strip 302 is big, uniform force, makes closely to connect between amorphous alloy strip, can effectively avoid non-crystaline amorphous metal
Gap is produced between band, reduces the generation of noise.
Above content is only to structure example of the present utility model and explanation, the technology of affiliated the art
Personnel are made various modifications or supplement to described specific embodiment or substituted using similar mode, without departing from
The structure of utility model surmounts scope defined in the claims, all should belong to the scope of protection of the utility model.
