Transformer also increases day by day, and the power transmission and transforming equipment such as transformer be directly placed in mostly it is in residential area or close from house
Place.But operationally easily there is problems with transformer：First, more serious ring is often produced during transformer station high-voltage side bus
Border vibration and noise pollution problem；2nd, transformer body vibration can be by rigid foundation and adjacent building structural elements to week
Propagation is enclosed, and structure borne noise may be induced.This directly affects the normal life of resident, result even in the nerveous system of people
System, digestive system, the discomfort of ear chamber.
The vibration and noise reducing for transformer most at present is installs blimp additional, as patent CN204558216U discloses one kind
Transformer denoising device, blimp is set by the surrounding in transformer shell, in the affixed fixed seat of blimp inwall, fixed seat
In the groove structure of opening, the inside grooves of fixed seat place sound-absorbing material (such as glass fibre, polyurethane foam plastics or
Mineral wool etc.), by setting cover plate to position the sound-absorbing material in fixed seat groove in the open-mouth of fixed seat.By becoming
The noise overwhelming majority of depressor enclosure interior outflow is absorbed by the sound-absorbing material in fixed seat, effectively prevents noise to unofficial biography
Broadcast.In the prior art, also have below transformer foundation plus different vibration isolation materials, also have by reduce iron core magnetic flux density come
Reduce noise caused by iron core.But also there is structure not in the vibration isolation material installed additional under the blimp or transformer foundation of existing installation
Enough reliable, imperfect deficiencies of effect, and the cost of transformer can be greatly increased by the way of iron core magnetic flux density is reduced, no
It is too economical.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of simple in construction, installation
Convenient, the transformer vibration damping denoising device of good damping result, the device use dual vibration isolation way, reduce the machinery of transformer
Vibration, extend the service life of transformer.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of transformer vibration damping denoising device, including be sequentially connected from the bottom to top polyurethane bumper absorber, central dividing plate, subtract
Shake rubber blanket and C-shaped channel steel frame, the polyurethane bumper absorber form a fixed connection with ground, the C-shaped channel steel frame openings
Side is nested in C-shaped channel steel frame towards yielding rubber pad, the yielding rubber pad, on the C-shaped channel steel frame opposite side
Transformer base is fixedly mounted in side.
Preferably, there is microporous bubble structure in the polyurethane bumper absorber.
Preferably, the yielding rubber pad is formed by two folded set of band boss rubber blanket, and is oppositely arranged with boss one side.
Preferably, the thickness with boss rubber blanket is 15~25mm.
Preferably, the C-shaped channel steel frame is square criss-cross construction.
Preferably, the polyurethane bumper absorber, central dividing plate, yielding rubber pad one damper unit of formation being sequentially connected,
The damper unit is provided with multiple, is nested in C-shaped channel steel frame, and in all directions equidistant arrangement with boss rubber blanket.
Preferably, the damper unit is provided with 9.
Preferably, polyurethane bumper absorber top, central dividing plate and the yielding rubber pad are nested in C-shaped channel steel frame
It is interior.
Compared with prior art, the present invention has advantages below：
(1) present invention sets polyurethane bumper absorber, central dividing plate, yielding rubber pad and the C-shaped channel steel frame being sequentially connected
Vibration and noise reducing device is formed, it is simple in construction, it is easy for installation, using dual vibration isolation way, the mechanical oscillation of transformer are reduced, are had
The adverse effect of the vibration for solving transformer and noise to surrounding environment is imitated, while also extends the use longevity of transformer equipment
Life.
(2) present invention employs the polyurethane bumper absorber with microporous bubble structure, energy-absorbing buffering effect are good.
(3) yielding rubber pad of the present invention is formed by two folded set of band boss rubber blanket, due to the work of boss between rubber blanket
With so as to there is gap, rubber blanket is set more effectively to reduce the mechanical oscillation of transformer.
(4) in the present invention, polyurethane bumper absorber top, central dividing plate and yielding rubber pad are nested in C-shaped channel steel frame
It is interior, buffering energy-absorbing can not only be played a part of, moreover it is possible to prevent whole vibration and noise reducing device recurring structure unstability.
(5) polyurethane bumper absorber is bolted with ground.So as to considerably reduce the vibrations of transformer to ground
Conduction, with reach reduce transformer vibrations and noise pollution purpose.
(6) in the present invention, the damper unit that is made up of polyurethane bumper absorber, central dividing plate, yielding rubber pad be provided with it is multiple,
Equidistant placement improves the reliability of whole device, further increases effectiveness in vibration suppression in C-shaped channel steel frame respectively.
