Description
Technical field
The utility model relates to a kind of transformer manufacturing technology, especially refers to amorphous alloy roll-core.
Background technology
The material of making at present transformer core mainly contains two kinds of silicon strip and non-crystaline amorphous metals, and non-crystaline amorphous metal is compared with silicon strip, is a kind of material of more energy-conservation manufacturing transformer core.
Non-crystaline amorphous metal is to adopt rapid quench to solidify production technology, and its physical state shows as metallic atom and is unordered noncrystal arrangement, is more conducive to be magnetized and degaussing.This material is used for transformer core, and the transformer magnetization process is very easy to, thereby reduces the no-load loss of transformer greatly.From the no-load loss reduction degree of transformer, amorphous alloy strips is that the silicon strip of all various trades mark at present is incomparable.
Because amorphous alloy strips is much thinner than silicon strip, much crisp, and hardness is almost 5 times of silicon strip, so the transformer production enterprise equipment that is used to the to cut silicon strip amorphous alloy strips of at all having no idea to cut.Want to produce amorphous alloy transformer, must buy iron core, and the enterprise of domestic existing two tame professional production amorphous alloy iron cores, also do not have the slitting equipment of non-crystaline amorphous metal, have only band to cut off equipment to the enterprise of professional production amorphous alloy iron core.
The present main dependence on import of amorphous alloy strips, the amorphous alloy strips width dimensions specification of import seldom, have only three kinds of 142cm, 170cm, 213cm, can't satisfy the requirement of different capabilities iron core, therefore when needing different cross-sectional for the iron core of different capabilities, often can only be mainly the gauge of rectangular shape by the change core section realize.The maximum length-width ratio of the cross section rectangle of present various capacity iron cores has reached 4.
Therefore, mainly there is following problem in existing amorphous alloy iron core:
A, since at present the amorphous alloy strips of external import have only the straight band of three kinds of width, therefore the iron core shape of cross section of making can only be that rectangle is a kind of, reaches 4 for the length-width ratio of the iron core cross section rectangle of some capacity, can not rounded or polygon.As everyone knows, the girth minimum of circle in the same sectional area shape, the girth of rectangle is bigger, and particularly length-width ratio is big more, and girth is just long more.And girth length must make the average turn of transformer coil long just long, not only wastes valuable copper, and can increase the load loss and the transformer temperature rise of transformer.
B, because the present iron core of amorphous alloy material, cross section can only be a rectangle, can not be circular, so coil shape can only be rectangle also, and can not be circular.Can't the ribbon core coiling.Therefore iron core can only be made the open type iron core, and can not be the closed type iron core.For being more suitable for adopting the remain silent small capacity transformer of volume iron core also can only adopt open type volume iron core.
The opening material of c, open type iron core will make material increase stress through repeatedly bending, the particularly material bending after annealing, makes the decreased performance of iron core, and no-load loss rises.
There are the space in d, open type iron core opening amorphous alloy material joint, and reason such as amalgamation defective tightness, and noise is bigger than the noise of the iron core of remaining silent with capacity.
E, opening amorphous alloy material are when closure, amorphous alloy material is subjected to bending, and the amorphous alloy material surface comes off easily, produces the fish scale tablet, these tablets float and cause transformer fault easily in transformer oil, and the fail safe of transformer is descended.
F, amorphous alloy material are because too thin, so the iron core rigidity of making is very poor, the weight that can't bear the line bag must increase the weight that supporting member bears iron core, increase the difficulty of device body assembling.
G, amorphous alloy material are relatively more expensive, and material source is single, is unfavorable for large-scale popularization.
In sum, in view of amorphous alloy material is that a kind of advantage is outstanding, but the also fairly obvious material of shortcoming, therefore, how to provide a kind of novel compound section amorphous alloy roll-core, keep this material advantage, overcoming its shortcoming, is one of the applicant's content of endeavouring to study.

In above-mentioned amorphous alloy roll-core, in described several single frames, be main frame with cross section the maximum, this main frame is directly to be with the material continuous reeling to form by non-crystaline amorphous metal, all the other single frames are to be formed by difform silicon strip continuous reeling.
In above-mentioned amorphous alloy roll-core, difform silicon strip is trapezoid belt, arcuate zone or straight band.
In above-mentioned amorphous alloy roll-core, several independently single frame adopt the suit mode and fit tightly fixingly with the single frame binding face mutually, amalgamation forms iron core integral body.
In above-mentioned amorphous alloy roll-core, the single frame of several mutual amalgamations is the single frame of remaining silent, and the iron core after the amalgamation is the volume iron core of remaining silent.
In above-mentioned amorphous alloy roll-core, the single frame of several mutual amalgamations is the opening single frame of U-shaped, and the iron core after the amalgamation is an open coil iron core.
In above-mentioned amorphous alloy roll-core, the volume iron core that several single frames piece together is single-phase volume iron core, three-phase three-column plane reeling iron core, three-phase and five-pole plane reeling iron core or three-phase stereo volume iron core.

B, saving amorphous alloy material: owing to the utility model part amorphous alloy material replaces with silicon strip, so can save the expensive amorphous alloy material of 10%-30%.
3, improve the iron core processing technology
Because the utility model adopts part silicon strip material to replace amorphous alloy material, has increased the rigidity of iron core, makes the iron core clamping, manufacturabilities such as carrying improve.
4, improved the reliability of transformer work
Because the utility model can make the volume iron core of remaining silent, do not need to carry out iron core and seal, so material do not need bending, significantly reduce coming off of fish scale tablet.Reduced possibility, improved the reliability of transformer work because of existing a large amount of fish scale tablets to cause transformer work to break down in the transformer.
