Description
Technical field
The present invention relates to technical field of transformation equipment, and in particular to a kind of three-dimensional winding iron core and transformer.
Background technique
Stereoscopic triangular coiled-core transformer has many advantages, such as three-phase magnetic circuit balance, low and low noise is lost, therefore by
The welcome and favor of more and more users.Iron core is generally made of silicon steel sheet or amorphous alloy material.However the magnetic of amorphous alloy
Cause coefficient of dilatation higher, the suffered constraint of the vibration of the amorphous alloy iron core as caused by magnetostriction is smaller, and vibration level is opposite
Larger, the noise accordingly generated is also larger；In addition amorphous alloy magnetic flux density can only take 1.0-1.35T, therefore usual and silicon steel
Mixing forms an iron core and uses.
As in the prior art, the utility model patent of Publication No. CN207474235U discloses a kind of silicon wafer composite stereo
Be open transformer core, including spatially triangular form setting iron core group, iron core group by three independences and size structure it is all the same
Single frame open core with central angleAngle it is assembled, the single frame open core be by internal layer silicon steel iron core, in
Central layer amorphous alloy core, outer layer silicon steel iron core are put together.The internal layer silicon steel iron core and outer layer silicon steel iron core are all made of
It is collapsible that there are eight bendingsOr the dual openings molding silicon steel material strip stack at 12 150 degree of angles forms.The internal layer silicon
Hollow space between the steel heart and central core amorphous alloy and central core amorphous alloy and outer layer silicon steel iron core is filled out using silica gel
It fills.
But above-mentioned patent has certain defect, due to two kinds of material properties differences of silicon steel and amorphous alloy, is orientated different
Mixing difficulty is used in mixed way caused by the reasons such as cause, flux density coefficient differ huge, and lamination value is different, and annealing temperature differs greatly
Greatly, the material property of amorphous alloy or silicon steel can be reduced.
Summary of the invention
Therefore, the technical problem to be solved in the present invention is that overcome in the prior art three-dimensional winding iron core due to silicon steel and amorphous
Two kinds of material properties differences of alloy, orientation is inconsistent, and flux density coefficient difference is huge, and lamination value is different, and annealing temperature difference is outstanding
It is big that it is used in mixed way mixing difficulty caused by the reasons such as different, the defect of silicon steel or amorphous alloy material performance can be reduced, to provide
A kind of three-dimensional winding iron core.
The invention solves another technical problem be to overcome in the prior art transformer neutral body volume iron core due to
Two kinds of material properties differences of silicon steel and amorphous alloy, orientation is inconsistent, and flux density coefficient difference is huge, and lamination value is different, annealing
It is used in mixed way that mixing difficulty is big caused by the reasons such as temperature difference great disparity, lacking for silicon steel or amorphous alloy material performance can be reduced
It falls into, to provide a kind of transformer.
A kind of three-dimensional winding iron core provided by the invention is mutually the single frame iron core of 60 degree of angles splicing, three institutes including three
It states at least one in single frame iron core to be made of amorphous alloy, at least one is made of silicon steel.
Optionally, in three single frame iron cores one be made of amorphous alloy, two are made of silicon steel, alternatively, two
It is made of amorphous alloy, two are made of silicon steel.
Optionally, the amorphous alloy is Fe-based amorphous alloy, iron-nickel-based amorphous alloy, cobalt base amorphous alloy or nanocrystalline
One of alloy.
Present invention simultaneously provides a kind of transformer, the three-dimensional winding iron core including any of the above-described.
Technical solution of the present invention has the advantages that
Three-dimensional winding iron core provided by the invention, single frame iron core are integrally made of amorphous alloy material or silicon steel, and at least
One single frame iron core is amorphous alloy, and having a single frame iron core is silicon steel；It is designed in this way, can separate and individually process, then combine
It for complete three-dimensional winding iron core, overcomes due to two kinds of material properties differences, orientation is inconsistent, and flux density coefficient difference is huge, folds
It is big that it is used in mixed way mixing difficulty caused by the reasons such as chip value is different, and annealing temperature differs greatly, silicon steel can be reduced or amorphous closes
The defect of golden material property.After the combination of iron core made of two kinds of materials, the superior function of amorphous alloy can be being kept with performance complement
At the basis of consumption energy, electromagnetic performance and cost advantage with silicon steel can reduce production cost, reduce silicon steel zero load yarn number,
Reduce the no-load current and noise, raising amorphous flux density yarn number of amorphous.
Detailed description of the invention
It, below will be to specific in order to illustrate more clearly of the specific embodiment of the invention or technical solution in the prior art
Embodiment or attached drawing needed to be used in the description of the prior art be briefly described, it should be apparent that, it is described below
Attached drawing is some embodiments of the present invention, for those of ordinary skill in the art, before not making the creative labor
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of structural schematic diagram of the three-dimensional winding iron core provided in the first embodiment of the invention；
Description of symbols:
1- single frame iron core.
Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
