Abstract
The utility model is related to a kind of new oil duct of amorphous alloy oil immersion transformer, belongs to power transformer manufacturing technology field.It is made up of insulating board, stay, glue, is characterized in：Equidistance is spaced on insulating board and is bonded with by glue on many stays, insulating board between uniform making there are every two stays being bonded on multiple circular holes, insulating board and is distributed a row circular hole；Circular hole constitutes indeformable oily free air space.Stay is indeformable during increasing oil flow channel endurance, coil winding and molding clamp, and oil passage spaces do not change, it is ensured that coil excellent radiating effect.The direct contact surface for increasing coil and oil is accumulated, good heat dissipation effect, reduces coil temperature rise, and extension oil becomes service life.Solve existing corrugated oil duct to be easily crushed deformation in coil-winding process and coil molding clamping process, coil and oil duct contact surface are small, the oily poor fluidity longitudinal in coil, cause that the radiating surface of coil is small, weak heat-dissipating, temperature rise, the problem of service life is low.
Description
Technical field
The utility model is related to a kind of new oil duct of amorphous alloy oil immersion transformer, category power transformer manufacturing technology neck
Domain.
Background technology
Electric power resource it is energy-saving, be the major tasks of national " 13 " implementing plan.Using new magnetic material
The transformer that amorphous alloy iron core is made, the open circuit loss than silicon sheet core transformer declines 80% or so, no-load current
Decline reaches 85%, is the preferable distribution transformer of current energy conservation and consumption reduction effects, is particularly suitable for rural power grids and transformer load rate
Lower ground side is used.But being used at present amorphous alloy oil immersion transformer through being molded the corrugated oil duct being machined into, to the greatest extent more
It is convenient that pipe makes, but can make in coil-winding process and coil molding clamping process corrugated oil duct flattening deformation, coil with
The contact surface of oil duct is small, and oil causes that the radiating surface of coil is small, poor radiation in the poor fluidity of coil longitudinal direction, temperature rise, sternly
Ghost image rings the service life of transformer.
The content of the invention
The purpose of this utility model is, coil and oil are increased there is provided a kind of for above-mentioned the deficiencies in the prior art
Direct contact surface, increase oil is in the mobility of coil longitudinal direction and the radiating surface of coil, and good heat dissipation effect is stable and reliable in work, has
Effect reduction coil temperature rise, extension oil becomes the new oil duct of the amorphous alloy oil immersion transformer of service life.
The utility model is to realize above-mentioned purpose by following technical solution：
The new oil duct of the amorphous alloy oil immersion transformer is made up of insulating board, stay, glue, it is characterised in that：Absolutely
Equidistance is spaced on edge cardboard and is bonded with many stays, insulating board uniformly to make by glue multiple circular holes, insulate
A row circular hole is distributed between every two stays being bonded on cardboard；Circular hole constitutes indeformable oily free air space.
The thickness of described insulating board is 1.0mm.
Described glue is high temperature resistant glue.
The beneficial effect of the utility model compared with prior art is：
The new oil duct of the amorphous alloy oil immersion transformer increases the endurance of oil flow channel by stay, so, online
Stay will not be deformed in circle winding process and coil molding clamping process, therefore oil passage spaces will not change, it is ensured that coil
With good thermal diffusivity.Uniform open is formed with many circular holes on the insulating board of 1.0mm thickness simultaneously, further increase coil with
The direct contact surface product of oil.Coil can be contacted fully with oil, and the heat for allowing for the generation of transformer station high-voltage side bus process coil can be big
Measure, conducted rapidly, good heat dissipation effect effectively reduces coil temperature rise, is that amorphous alloy oil immersion transformer is reliable and stable
Operating provides powerful guarantee, greatly prolongs its service life.Solve existing corrugated oil duct coil-winding process and coil into
Easily be crushed deformation in type clamping process, and coil and oil duct contact surface are small, and oil causes coil in the poor fluidity of coil longitudinal direction
Radiating surface is small, poor radiation, and operating temperature is high, the problem of having a strong impact on amorphous alloy oil immersion transformer service life.

Embodiment
The embodiment to the new oil duct of the amorphous alloy oil immersion transformer is done further specifically below in conjunction with the accompanying drawings
It is bright：
The new oil duct of the amorphous alloy oil immersion transformer is made up of insulating board 1, stay 2, glue 3, on insulating board 1
Interval equidistance is bonded with many stays 2, insulating board 1 uniform make by glue 3 multiple circular hole 1-1, insulating paper
A row circular hole 1-1 is distributed between every two stays 2 being bonded on plate 1；Circular hole 1-1 constitutes indeformable oily free air space.
The thickness of described insulating board 1 is 1.0mm.
Described glue 3 is high temperature resistant glue.（Referring to Fig. 1~2）
The operation principle of the new oil duct of the amorphous alloy oil immersion transformer is as follows：
Existing amorphous alloy oil immersion transformer oil passage generally uses corrugated oil duct, by the thick insulating papers of 1.5mm or 2.0mm
Plate is processed by corrugation former, and such corrugated oil duct can quilt in coil-winding process and coil molding clamping process
Flattening deformation, so that cause oil duct small, weak heat-dissipating, coil temperature rise.And the utility model amorphous alloy oil immersion transformer
New oil duct uses the frame mode of stay 2+1.0mm insulating boards 1, and uniform open makes circular hole on 1.0mm insulating boards 1
1-1, stay 2 and 1.0mm insulating board 1 is firmly bonded together by glue 3.Pressed from both sides in coil-winding process and coil molding
Stay 2 will not be deformed during tight, therefore oil passage spaces will not change, it is ensured that the good thermal diffusivity of coil.1.0mm insulation
Multiple circular hole 1-1 of system are opened on cardboard 1, the direct contact surface for further increasing coil and oil is accumulated, stream of the increase oil in coil longitudinal direction
Dynamic property.Because coil can be contacted directly with oil well, therefore it ensure that the heat energy that transformer station high-voltage side bus process coil is produced
Conducted well, effectively the service life of extension oil-immersed type transformer, improve production efficiency.
Simply preferred embodiment of the present utility model described above, the example above illustrates not to reality of the present utility model
Matter content makees any formal limitation, and person of an ordinary skill in the technical field is after this specification has been read according to this reality
