Technical field
The present invention relates to technical field of transformation equipment, and in particular to a kind of plane reeling iron core and transformer.
Background technique
Transformer (Transformer) is the device for changing alternating voltage using the principle of electromagnetic induction, main member
It is primary coil, secondary coil and iron core (magnetic core).Novel energy-conserving transformer and traditional transformation by amorphous alloy production iron core
Device is compared, and 70% or more no-load loss decline, no-load current decline about 80%, is the preferable distribution transformer of current energy-saving effect
Device.
However the magnetostriction coefficient of amorphous alloy is higher, suffered by the vibration of the amorphous alloy iron core as caused by magnetostriction
Constrain smaller, vibration level is relatively large, and the noise accordingly generated is also larger；In addition amorphous alloy magnetic flux density can only take
1.0-1.35T, therefore usually form an iron core with silicon steel mixing and use.
However due to two kinds of material properties differences of silicon steel and amorphous alloy, orientation is inconsistent, and flux density coefficient difference tool is big, 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, amorphous alloy or silicon can be reduced
The material property of steel.
Summary of the invention
Therefore, the technical problem to be solved in the present invention is that overcome in the prior art plane reeling iron core due to silicon steel and amorphous
Two kinds of material properties differences of alloy, orientation is inconsistent, and flux density coefficient difference tool is big, and lamination value is different, and annealing temperature difference is hanged
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 plane reeling iron core.
The invention solves another technical problem be to overcome in transformer in the prior art plane reeling iron core due to
Two kinds of material properties differences of silicon steel and amorphous alloy, orientation is inconsistent, and flux density coefficient difference tool is big, 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 plane reeling iron core provided by the invention includes at least two iron cores arranged in plane, at least one described iron
Core is made of amorphous alloy, remaining described iron core is made of silicon steel.
Optionally, including two interior iron cores being set side by side and the outer iron core for being sheathed on two interior outer diameters,
At least one in the outer iron core and two interior iron cores is made of amorphous alloy, remaining is made of silicon steel.
Optionally, including four sub- iron cores being set side by side, at least one described sub- iron core is made of amorphous alloy, remaining

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 plane reeling iron core including any of the above-described.
Technical solution of the present invention has the advantages that
Plane reeling iron core provided by the invention, iron core are integrally made of amorphous alloy material or silicon steel, and at least one
Iron core is amorphous alloy, and having an iron core is silicon steel；It is designed in this way, can separate and individually process, then group is combined into complete plane
Iron core is rolled up, is overcome due to two kinds of material properties differences, orientation is inconsistent, and flux density coefficient difference tool is big, and lamination value is different, moves back
It is used in mixed way that mixing difficulty is big caused by the reasons such as fiery temperature difference great disparity, lacking for silicon steel or amorphous alloy material performance can be reduced
It falls into.It, can be with performance complement, on the basis for keeping the superior power consumption performance of amorphous alloy after the combination of iron core made of two kinds of materials
Place, electromagnetic performance and cost advantage with silicon steel can reduce production cost, reduce silicon steel zero load yarn number, reduce the sky of amorphous
It carries electric current and noise, improve amorphous flux density yarn number.
