Embodiment
The core of the utility model is used the high pressure mould for a kind of Transformer Winding is provided, and this high pressure mould can realize improving the purpose of the magnetic conductivity of permeability magnetic material in the transformer through its structural design.
In order to make those skilled in the art understand the technical scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and specific embodiment.
Please refer to Fig. 1, Fig. 1 be among a kind of embodiment of the utility model Transformer Winding with the structural representation of high pressure mould.
The utility model provides a kind of Transformer Winding to use the high pressure mould, is used for the winding assembling of high-tension transformer winding, comprises internal mold die body 1, support plate 2 and external mold die body 3.Be provided with support plate 2 in the internal mold die body 1, support plate 2 is used for internal mold die body 1 is strutted, and support plate 2 also has the supporting role to internal mold die body 1, thereby makes the size of internal mold die body 1 reach designing requirement, and internal mold die body 1 is used to twine winding.External mold die body 3 is sheathed on the outside of internal mold die body 1, and and internal mold die body 1 between have the gap that is used for ccontaining winding.
The Transformer Winding that the utility model provided is used the high pressure mould, because winding all is to be wound on the mould, if improve the purpose that the magnetic property of mould just can realize improving the magnetic conductivity of permeability magnetic material in the transformer.So the utility model adopts the non-crystaline amorphous metal irony to process with the high pressure mould Transformer Winding.Fe-based amorphous alloy has high saturated magnetic induction and low-loss characteristics, adopts the mould that the utility model provided to carry out the winding coil winding, can improve the magnetic conductivity of transformer.
To make an explanation to non-crystaline amorphous metal below.The material of people's contact generally has two kinds in daily life: a kind of is crystalline material, and another kind is an amorphous material.So-called crystalline material is meant that the atomic arrangement of material internal is followed certain rules.Otherwise inner atomic arrangement is in random state, then is amorphous material, general metal, and its inner atomic arrangement is orderly, all belongs to crystalline material.Scientist finds that metal is after fusing, and inner atom is in active state.Metal begins to cool down, and atom will be along with decrease of temperature, and lines up in an orderly manner according to certain crystalline state rule at leisure, forms crystal.If cooling procedure is very fast, atom also has little time just to arrange again and has been solidified, and has just produced amorphous alloy thus, the technology of a kind of rapid solidification just that the preparation amorphous alloy adopts.The high-temp liquid that will be in molten condition is ejected on the chill roll of high speed rotating.Alloy liquid cools off rapidly with the speed of per second 1,000,000 degree, only just 1300 ℃ alloy liquid is dropped to room temperature, the formation amorphous band with time of signa.
