Description
Technical field
The utility model relates to transformer noise reduction field more particularly to a kind of transformer noise reduction components.
Background technique
The harm of noise on human body is very big, is chronically at the physical and mental health that will affect people in the environment of influence of noise, becomes
The sound source of depressor mostlys come from three aspects: first is that iron coring vibration caused by the magnetostriction of silicon steel sheet；Second is that silicon steel sheet connects
Cause the vibration of iron core at seam there is the electromagnetic attraction generated due to leakage field between lamination；Third is that negative when having in winding
When load electric current passes through, the leakage field that load current generates causes the vibration of coil, oil tank wall.It can be seen that changing the installation of transformer
Mode makes it be flexibly connected the generation that can fundamentally reduce noise by being rigidly connected to be converted to.Existing transformer installation
Flexible connection mostly use spring supporting, but after spring failure, then destructive destruction can be caused to transformer.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of transformer noise reduction group
Part, to guarantee the stability of transformer support while reducing noise.
Technical solution: to achieve the above object, a kind of transformer noise reduction components of the utility model, including support column, set
Cylinder and several dampening assemblies；The dampening assembly includes upper padding plate, lower bolster and several damping springs, the upper padding plate and underlay
For plate between the upper and lower every setting, upper padding plate and lower bolster are separately connected several damping springs, the support column is axially disposed have it is several
Annular shirt rim, the damping spring of the upper padding plate and the damping spring of lower bolster are compressed to the upper and lower surface of annular shirt rim respectively,
Several annular grooves are provided in the sleeve, the dampening assembly is set in annular groove.
Further, the upper and lower surface of the annular shirt rim is respectively arranged with diving board, and the diving board is sheathed on outside support column,
The damping spring is compressed with diving board to be connect, and the diving board is provided with protrusion along inner ring.
Further, the upper padding plate and lower bolster are silica gel material.
Further, the upper padding plate and the opposite surface of lower bolster are provided with several salient points.
Further, the sleeve includes inner sleeve and outer sleeve, and the inner sleeve is sheathed on the inside of outer sleeve, described
Inner sleeve and outer sleeve are divided into left and right two parts, and wherein left and right two parts of outer sleeve are bolted；The annular is recessed
Slot is set to the inner surface of inner sleeve.
Further, the inner surface of the outer sleeve is axially disposed several annular fixed lobes, the sleeve it is outer
Surface is provided with several annular fixing grooves, and the fixed lobe and fixing groove are cooperatively connected.
The beneficial effects of the utility model are as described below: a kind of transformer noise reduction components described in the utility model, utilize
Sleeve, dampening assembly and the cooperation of support column connect common transformer rigid support, become flexible support connection, by subtracting
It is few to vibrate to reduce the generation of noise；The wherein damping spring in dampening assembly, is wrapped up by sleeve, reduces corrosion speed
Degree；When damping spring failure, the annular shirt rim of support column is connected by supporting with lower bolster, since lower bolster is silica gel material
Material, therefore also have the effect of damping noise reduction.
Detailed description of the invention
Attached drawing 1 is the schematic diagram of the utility model and transformer support connection；
Attached drawing 2 is the structure sectional view of the utility model；
Attached drawing 3 is the Structure explosion diagram of the utility model；
Attached drawing 4 is the structural schematic diagram that dampening assembly described in the utility model is connect with diving board.
Specific embodiment
