Description
Technical field
The utility model relates to a kind of transformer core, and specifically, it is unshakable in one's determination that the utility model relates to a kind of composite type by laminated structure, and particularly tabs Combined coiled is unshakable in one's determination.
Background technology
Iron core is the main component of transformer, and the electromagnetic performance of transformer depends on core construction to a great extent.The supporting iron core of conventional transformer adopts silicon steel sheet to be formed by stacking, on market transformer majority be alternately flat lamination, although the iron core production difficulty of this kind of structure is little, is easy to fitting coils and installs.But, alternately the iron core of flat lamination also exposes some problems in actual use, be first unshakable in one's determination every layer by multi-disc alternately flat folded silicon steel sheet form, have six road abutment joints in this structure at least, abutment joint is real in magnetic circuit is a kind of air-gap, and too much air-gap directly increases the magnetic resistance of magnetic circuit.Next be flat folded silicon steel sheet because of folded position difference cause magnetic circuit and material height magnetic conduction direction inconsistent.Another problem is defective tightness between flat folded silicon steel sheet, and the iron core that lamination coefficient is low is in operation and produces larger noise.Closo core construction is the representative now structure of the industry, and it is by wide silicon strip coiling and molding.Closo core construction avoids the deficiency of alternately flat lamination, does not both have air-gap in structure, can accomplish that again the silicon steel of magnetic circuit and winding is with consistent high magnetic conduction direction., closo manufacture difficulty unshakable in one's determination is than alternately flat stack structure is many greatly, and particularly coil is directly around on iron core, and except directly strengthening except the supporting requirement of production equipment, production efficiency is also lower, so application is subject to a definite limitation.
Utility model content
The utility model is mainly for the deficiencies in the prior art, and propose the tabs Combined coiled that a kind of structure is simple, tabs is easy, easy to assembly, electromagnetic performance is excellent unshakable in one's determination, this structure accomplishes that the magnetic flux on magnetic circuit circulates along silicon strip rolling direction.
The utility model is achieved through the following technical solutions technical goal.
Tabs Combined coiled is unshakable in one's determination, and it is made up of jointly female male iron core with matching unshakable in one's determination.Described female iron core uses gang's shape identical with male iron core respectively, and the grooved silicon steel sheet that size does not wait is stacked shaping, and the sheet of every flute profile silicon steel sheet is thick, sheet is wide equal.Its improvements are: two right angles of described flute profile silicon steel sheet are converted into truncated right, every sheet both sides right-angle side length is equal, and the single-candidate change in order of adjacent superimposed flute profile silicon steel sheet both sides right-angle side length, it is thick that adjacent superimposed flute profile silicon steel sheet groove width differs two synusia.The flute profile silicon steel sheet both sides right-angle side length be stacked in described female iron core lengthens in order from internal layer outer layers, is stacked stepmother's inner chamber unshakable in one's determination and forms interior hierarchic structure; The flute profile silicon steel sheet both sides right-angle side length be stacked in public iron core shortens in order from internal layer outer layers, and arrangement of successively decreasing forms outer hierarchic structure, female rectangle frame rewinding material coordinated with male iron core in complementary shape corner truncation unshakable in one's determination.
In said structure, truncated corner α=40, both sides of flute profile silicon steel sheet
0~ 50
0, innermost layer truncation hypotenuse E=3 ~ 5mm.
The utility model compared with prior art, has following good effect:
1, the flute profile silicon steel sheet of rewinding material bending and forming is stacked successively and forms, therefore assembling is without mould, and production efficiency is high, production cost is low;
2, rewinding material is stepped construction, does not have residualinternal stress in structure, saves annealing operation;
3, rewinding material is combining structure, therefore coil and rewinding material separate and make, and is conducive to producing;
4, form complementary structure when female iron core and male iron core combination, every layer only has 2 road abutment joints, and the magnetic resistance in magnetic circuit is close with closo rewinding material, is conducive to improving transformer operational efficiency, reduces noise.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Tabs combine volume shown in Fig. 3 is unshakable in one's determination, and it forms with the male iron core 2 of pairing jointly by female unshakable in one's determination 1.Described female unshakable in one's determination 1 uses gang's shape identical with male iron core 2 respectively, and the differentiated flute profile silicon steel sheet of size is stacked shaping, and as shown in Figure 5, the thick C of sheet of every flute profile silicon steel sheet is equal with the wide A of sheet.Flute profile silicon steel sheet two jiaos is converted into truncated right, and α=45 are pressed on the present embodiment opposing right angles limit
0truncation, internal layer truncation hypotenuse E=3mm, follow-up superimposed layer then every layer increase progressively by the thick C of sheet.Every sheet both sides right-angle side length H single-candidate change in order, adjacent superimposed flute profile silicon steel sheet groove width B differs the thick C of two synusia.Described female unshakable in one's determination 1 and male iron core 2 in the whole different length of flute profile silicon steel sheet both sides right-angle side that is stacked, it is equal that every fault opens length.Mother shown in Fig. 1 unshakable in one's determination 1 it lengthened in order by internal layer outer layers, be stacked stepmother's 1 inner chamber unshakable in one's determination and form interior hierarchic structure.Public affairs iron core 2 shown in Fig. 2 is also a kind of iterative structure, built-in flute profile silicon steel sheet puts in order then contrary with mother's iron core 1, namely the flute profile silicon steel sheet both sides right-angle side length be stacked in public iron core 2 shortens in order from internal layer outer layers, and arrangement of successively decreasing forms outer hierarchic structure.When combination is installed, male unshakable in one's determination 2 insert in female unshakable in one's determination 1, and the outer hierarchic structure on male 2 both sides unshakable in one's determination coordinates with the interior hierarchic structure on mother's iron core 1 inner chamber both sides, and the flute profile silicon steel sheet complementation that namely male iron core 2 and mother's iron core 1 are in same layer becomes a corner by α=45
0the rectangle frame of truncation, all so complementary rewinding material just formed as shown in Figure 3, Figure 4 of every one deck.The rewinding material every layer of this structure only has 2 abutment joints, 4 abutment joints are at least deducted than conventional alternately flat lamination, only many 1 abutment joints compared with closo iron core, add the high magnetic conduction direction that magnetic circuit and silicon strip are consistent, the utility model and closo iron core have close electromagnetic performance thus.On the other hand, the utility model rewinding material is combining structure, can accomplish coil and rewinding material split manufacture, be conducive to enhancing productivity, be conducive to improving the quality of products.
