Abstract
The utility model discloses a three-frame three-column amorphous alloy iron core, which comprises two inner-frame iron cores and an outer-frame iron core. The two inner-frame iron cores are parallelly positioned inside the outer-frame iron core; the length of an air gap of each inner-frame iron core is the same with that of an air gap of the outer-frame iron core; and a group offset L of the outer-frame iron core is at least 50 millimeters. After adopting the structure, the amorphous alloy iron core can prevent the iron cores without the air gaps from being abutted to laps in a jamming manner, lead the air gaps of the iron cores to be more scattered in distribution, decrease drastic changes of magnetic flux in a small range, improve distribution of the magnetic flux and reduce no-load loss and noise of the amorphous alloy iron core.
Description
Technical field
The utility model relates to a kind of three frame three-column transformer iron cores, relates in particular to a kind of three frame three-column transformer iron cores that are made of amorphous alloy.
Background technology
In electric power system, send out, for, mainly comprise line loss and transformer loss two large divisions with the electric energy loss of electric process.Non-crystaline amorphous metal is a kind of new energy-saving material, adopts rapid quench to solidify production technology, and its physical state shows as metallic atom and is unordered noncrystal arrangement, and it is different fully with the crystal structure of silicon steel, is more conducive to be magnetized and degaussing.This new material is used for transformer core, and the transformer magnetization process is quite easy, thereby reduces the no-load loss of transformer significantly.Amorphous alloy iron core is to roll by one group of one group of amorphous alloy strips overlap joint to form.Add man-hour at iron core, the design lap length is at 8 to 15 millimeters, and the air gap between the joining seam is at 1 to 3 millimeter, and the group side-play amount of iron core is in 18 millimeter.It mainly is dry type amorphous transformer at oil immersed type amorphous transformer and four frames, five posts that these parameters are provided with.Along with the energy-saving effect of amorphous transformer more and more obtains the cognition in market, the use of amorphous transformer is more and more wider, and amorphous alloy iron core has begun to use on three frames, three post amorphous transformers, and capacity is increasing.Because the variation of band lamination coefficient, the folded thick of band also can change thereupon, and the fitting allowance that the time leaves in design of iron core, make that the external diameter of inside casing iron core is littler than the internal diameter of housing iron core, therefore in the cover process of assembling of iron core, the lap length of inside casing amorphous iron core the phenomenon of air gap even joining seam dieback occurs not having greater than the group side-play amount of iron core, and people often adopt the external diameter that enlarges the inside casing iron core at the internal layer pad rubber cushion blocks of amorphous iron core.Such result has a strong impact on assembly quality and iron core performance.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of solution housing iron core, inside casing iron core when suit, the phenomenon of air gap and dieback and suit do not appear in inside casing iron core joining seam finish after the same three frames, the three pillar amorphous alloy iron cores of gas length of housing iron core, inside casing iron core, improve the performance of three frames, three pillar amorphous alloy iron cores.
For achieving the above object, the technical solution of the utility model provides a kind of three frames, three pillar amorphous alloy iron cores, comprise two inside casing iron cores and a housing iron core, two inside casing iron cores are positioned at the hollow of described housing iron core side by side, described inside casing iron core and housing iron core are made up of some groups of amorphous alloy strips, described inside casing iron core air gap is identical with the length of housing iron core air gap, and housing iron core group side-play amount L is at least 50 millimeters.
Increase the internal diameter of housing iron core, in suit, just can avoid the inside casing iron core phenomenon of air gap and joining seam dieback to occur not having.Because by increasing the mode of amorphous alloy strips girth, rather than the mode that increases the air gap of housing iron core increases the internal diameter of housing iron core, so both reached the purpose that increases housing iron core internal diameter, it is identical with the length of housing iron core air gap to satisfy the inside casing iron core air gap again.The group side-play amount of iron core is in 18 millimeter in the prior art, by increase the amorphous alloy strips girth make housing iron core group side-play amount be 50 millimeters or more than.
The utility model with respect to the advantage of prior art is:
1, can avoid the inside casing iron core not have the phenomenon of air gap and joining seam dieback.
2, housing iron core group side-play amount increases at least 50 millimeters from 18 millimeters of prior art, the housing iron core air gap distributes and disperses more, has reduced magnetic flux among a small circle drastic change, has improved the distribution of magnetic flux, has reduced the no-load loss and the noise of amorphous alloy core.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of execution mode of the utility model three frames three pillar amorphous alloy iron cores.
Fig. 2 be in the execution mode shown in Figure 1 housing iron core amorphous alloy strips bridging arrangement partial schematic diagram.
Wherein, 1, inside casing iron core; 2, housing iron core; 3, joining seam; 5, air gap.
Embodiment
As shown in Figure 1 and Figure 2, a kind of three frames, three pillar amorphous alloy iron cores of the present utility model, comprise two inside casing iron cores 1 and a housing iron core 2, two inside casing iron cores 1 are positioned at the hollow of described housing iron core 2 side by side, an arm of an inside casing iron core 1 is adjacent with an arm of another inside casing iron core 1, and another arm of two inside casing iron cores 1 two arms with housing iron core 2 respectively is adjacent.Inside casing iron core 1 and housing iron core 2 are rolled by some groups of amorphous alloy strips overlap joints and form, and the amorphous alloy strips girth of housing iron core 2 is elongated, and 2 groups of side-play amounts of housing iron core are at least 50 millimeters, and the inside casing iron core air gap is identical with the length of housing iron core air gap 5.
As shown in Figure 2, overlapping one section of the two adjacent groups amorphous alloy strips of two adjacent groups amorphous alloy strips lap-joint is a joining seam 3, and the length of joining seam 3 is L2; Space between same group of amorphous alloy strips two ends is an air gap 5, and air gap length is L1; One group of amorphous alloy strips left side exceeds another distance of organizing amorphous alloy strips 4 left sides for the group side-play amount in the two adjacent groups amorphous alloy strips, represents with L.
