But easily there is following problem in transformer in the time of operation: when one, transformer moves, often produce comparatively serious ambient vibration and problem of noise pollution; Two, transformer body vibration can be propagated towards periphery by rigid foundation and adjacent building structural elements, and may bring out structure borne noise. This has directly affected resident's normal life, even can cause people's nervous system, digestive system, the discomfort in ear chamber.
At present most vibration and noise reducing for transformer is for installing blimp additional, as patent CN204558216U discloses a kind of transformer denoising device, by the surrounding at transformer shell, blimp is set, at the affixed holder of blimp inwall, holder is uncovered groove structure, inside grooves at holder is placed sound-absorbing material (such as glass fibre, polyurethane foam plastics or mineral wool etc.), positions with the sound-absorbing material in holder groove by cover plate is set at the open-mouth of holder. The sound-absorbing material that the noise overwhelming majority being spread out of by transformer shell inside is fixed in seat is absorbed, and has effectively stoped noise outwards to be propagated. In prior art, also have and below transformer foundation, add different vibration isolation materials, also have by reducing iron core magnetic flux density and reduce the noise that iron core produces. But the vibration isolation material installing additional under the existing blimp installing additional or transformer foundation also exists, structure is reliable not, the imperfect deficiency of effect, and the mode of employing reduction iron core magnetic flux density can increase the cost of transformer greatly, not too economical.
Summary of the invention
Object of the present invention is exactly the transformer vibration damping denoising device that a kind of simple in structure, easy for installation, good damping result is provided in order to overcome the defect that above-mentioned prior art exists, this device adopts dual vibration isolation way, reduce the mechanical oscillation of transformer, extended the service life of transformer.
