Description
Technical field
The utility model relates to field of electrical equipment, in particular to a kind of amorphous alloy variable pressure for optimizing the strapped structure of iron core
Device.
Background technique
Amorphous alloy transformer is the power transformer of a kind of low-loss, high energy efficiency, the policy to lower consumption with national energy-saving
Constantly promote；Make it is strong it is reliable, economical and efficient, clean and environmental protection modern power network policy deepen continuously, traditional high energy consumption
Transformer is faced with update or substitution, and amorphous alloy transformer is widely used based on the factor of energy supply and environmental protection.
And amorphous alloy core is caused under identical parameters due to the particular attribute of its material itself, amorphous alloy transformer
It is bigger than traditional silicon steel transformer noise.The noise of amorphous alloy transformer mainly as caused by the magnetostriction of permeability magnetic material,
Because magnetostrictivity is greater than traditional silicon steel sheet, therefore causes noise serious compared with silicon steel transformer；Secondly as amorphous alloy core
Folder should not be clamped excessively, and folder restraining force is small, so that the vibration of amorphous alloy core be caused to aggravate.
Simultaneously as amorphous alloy is extremely sensitive to mechanical stress, iron core stress senior general will affect its electromagnetic performance, due to
The no-load loss size of amorphous alloy transformer iron core and iron core when operation are directly proportional by pressure, therefore the prior art is all made of iron core
Iron core is suspended on coil by suspended structure, this structure can to avoid iron core become primary load bearing component, reduce iron core by
Power, so that transformer noload losses be effectively reduced.And this core construction cause assembly when in conplane iron core due to
Gravity factor and sink, so that the upper and lower end face of iron core is led to the increase of no-load loss not in same plane.
The noise level of amorphous alloy transformer is that measurement transformer technology advance and reliability and performance are excellent
The more important indicator of property.No-load loss problem, has seriously affected amorphous alloy variable pressure in the running noises of amorphous alloy and assembly
The running quality of device has significant impact to the safe and stable operation of power grid.
Summary of the invention
In order to overcome the deficiencies of the prior art, the utility model provides a kind of amorphous alloy change for optimizing the strapped structure of iron core
Depressor, reduce amorphous alloy core due to folder restraining force it is small caused by vibrating noise；Amorphous alloy core is avoided to assemble simultaneously
When the increased problem of no-load loss, guarantee the running quality of amorphous alloy transformer.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of amorphous alloy transformer optimizing the strapped structure of iron core, comprising: amorphous alloy core, sound absorbing layer, thermal contraction
Band, PET bandage；
Wherein, amorphous alloy core >=2 of the amorphous alloy core；The amorphous alloy core outer surface is wound with one
Layer sound-absorbing material, forms sound absorbing layer；Outside the core limb of the amorphous alloy core and the sound absorbing layer of upper yoke, uniformly and between waiting
Away from one layer of shrink belt of winding；The shrink belt outer layer is coated with liquid curing material, forms cured layer；Described adjacent two
Core limb on the inside of amorphous alloy core is placed against, at the core limb top being placed against and middle part and lower part three,
It is equally spaced PET bandage；Lower yoke opening lap-joint arranges PET bandage；
Compared with prior art, the utility model has the advantage that
1, the sound absorbing layer on wound core surface has completely cut off the vibrating noise generated by amorphous alloy core magnetostriction, really
Protect the noise problem that amorphous alloy core is solved from root.
2, the radially even contraction under thermodynamic activity of the shrink belt outside sound absorbing layer；Hot melt adhesive layer melts simultaneously, uniformly
Package is filled in amorphous alloy core surface, reduces the Oscillation Amplitude of amorphous alloy core, to achieve the purpose that reduce noise.
3, the liquid curing layer that shrink belt outer layer is smeared blocks falling for iron core chips, ensure that amorphous alloy variable pressure
The safe operation of device.
4, PET bandage has that high-intensitive, heat resistance is excellent, tensile strength is big, good insulation preformance, high pressure resistant, not residue glue
The characteristics of, and PET saves the time without solidification, binds high-efficient.Strapped two adjacent inner core columns simultaneously, it is ensured that
The upper and lower end face of iron core is in same level in amorphous alloy core assembling process, avoids leading to iron because self gravity influences
The heart is not in same plane, the problem of causing no-load loss to increase, it is ensured that the high quality of amorphous alloy transformer is run.
5, the lap-joint of lower yoke is strapped by PET bandage, avoids the loosening of amorphous alloy core opening, plays reduction and make an uproar
The purpose of sound.
