Abstract
The utility model relates to a damping device, in particular to a damping device for reducing the noise of a dry type transformer, wherein the damping device is mainly applied to the condition that the bottom of the transformer contacts with the ground. The damping device comprises a transformer; a transformer body foot pad is fixed at the bottom of the transformer; a damping device is arranged at the bottom of the transformer body foot pad and comprises a damping block; a concave damping spring notch is formed at the upper end of the damping block; and a damping spring is arranged in the damping spring notch. The damping device for reducing the noise of a dry type transformer has the advantages of the structure is simple, noise is reduced and the product quality is improved.
Description
Technical field
The utility model patent relates to a kind of damping device, relates in particular to a kind of damping device that reduces the dry-type transformer noise, and the bottom that is mainly used in transformer contacts with ground.
Background technology
Present dry-type transformer of the prior art is widely used in the place of people's work such as commercial center, office block, residential quarters, life; And the raising of Along with people's environmental consciousness and environmental administration are to the restriction of each noise like; Noise when how to control the dry-type transformer operation has become a crucial problem.Vibrations are roots that noise produces, and transformer noise is because vibrations unshakable in one's determination and the propagation through coupled object take place.
Chinese patent CN200920193879.0; A kind of amorphous alloy core transformer of low noise is disclosed; It is characterized in that: between the lower yoke of said amorphous alloy core and the lower clamping piece cushion block is set, lower clamping piece is provided with the position adjusting mechanism of regulating this cushion block degree of tightness.This complex structure, and result of use is undesirable, assembling trouble simultaneously.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, and the damping device of the outstanding reduction dry-type transformer noise of result of use.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of damping device that reduces the dry-type transformer noise; Comprise transformer; The bottom of described transformer is fixed with transformer body pad pin, and the bottom of described transformer body pad pin is provided with damping device, and described damping device comprises snubber block; The upper end of described snubber block is provided with the damping spring breach that concaves, and is provided with damping spring in the described damping spring breach.
Install 4 damping spring vibration isolators between transformer body and the ground additional and realize isolating vibrations, reduce noise.Can make vibration wave interreflection in the vibration absorber of band damping spring of transformer like this, repeatedly obtain to absorb, can reduce significantly through resonance and transmit noise.
As preferably, described damping spring is provided with pressing plate, and the width of described pressing plate is smaller or equal to the width of damping spring breach, and described pressing plate and transformer body pad pin fix through bolt.
As preferably, four jiaos of described transformer body pad pin are respectively equipped with damping device.
The utility model provides a kind of damping device that reduces the dry-type transformer noise, and is simple in structure, reduces noise, promotes product quality.
