Abstract
The utility model discloses a damping device for reducing noise of dry type transformer, acoustic celotex board including laying iron core on a kind is reduced dry -type transformer bottom and can seal dry -type transformer sets up the vibration damper plate below the acoustic celotex board, set up the damping spring between 1 at vibration damper plate and acoustic celotex board, the utility model discloses the harmful effects that outside vibrations produced dry -type transformer in the transportation can fall in simple structure effectively, can reduce dry -type transformer's noise simultaneously effectively, improve field force's comfort level, have solved the shock resistance vibrations problem of transformer in the mobile substation transportation, improve the quality of product.
Description
Technical field
The utility model relates to a kind of damping device reducing dry-type transformer noise, belongs to power equipment transport servicing unit technical field.
Background technology
The particularity of mobile substation is in addition; transformer is positioned on the car of frequent motion; the external factor such as road conditions can cause damage to transformer under possibly cannot estimating the vibrations produced in actual capabilities; personnel on site may be needed to safeguard in using simultaneously; therefore also have higher requirement to noise; so the noise reduction measure of dry-type transformer, for adopt acoustical cotton in the core which, exists not environmentally or inflammable risk usually.
Utility model content
The purpose of this utility model is: for the upper defect of prior art, provides a kind of damping device reducing dry-type transformer noise, both can reduce noise, can ensure again the fail safe in transformer transporting process, to overcome the deficiencies in the prior art.
The technical solution of the utility model
Reduce a damping device for dry-type transformer noise, comprise and be laid on a kind of to reduce bottom dry-type transformer and can the sound panel of sealing dry type transformer upper core, vibration damper plate is set below sound panel, damping spring is set between vibration damper plate and sound panel 1.
Aforesaidly a kind ofly reduce in the damping device of dry-type transformer noise, vibration damper plate upper surface arranges blind hole, damping spring is placed in blind hole, snubber block is made to keep surfacing by arranging blind hole and being placed in blind hole by damping spring, sound panel contacts with snubber block well, damping spring effectively can ensure the stability of its work in blind hole simultaneously, in the damping ensureing realize again under to the prerequisite of transformer stable support transformer.
Owing to have employed technique scheme, compared with prior art, the utility model structure is simple, the harmful effect that the vibrations of transportation peripheral produce dry-type transformer can be fallen effectively, effectively can reduce the noise of dry-type transformer simultaneously, improve the comfort level of Field Force, solve the shock resistance vibration problems of transformer in the transportation of mobile substation, improve the quality of product.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing to the utility model with being described in further detail, but not as to any restriction of the present utility model.
Embodiment of the present utility model: a kind of shock-dampening method reducing dry-type transformer noise, it is characterized in that: the method lays sound panel and the iron core of this sound panel energy sealing dry type transformer bottom dry-type transformer, thus reduce the noise of formula transformer, below sound panel, vibration damper plate is set, damping spring is set between vibration damper plate and sound panel thus realizes the damping to dry-type transformer, vibration damper plate upper surface arranges blind hole, and damping spring is placed in blind hole.
A kind of damping device reducing dry-type transformer noise constructed by said method, as shown in drawings, comprise and be laid on a kind of to reduce bottom dry-type transformer and can the sound panel 1 of sealing dry type transformer upper core, vibration damper plate 2 is set below sound panel 1, damping spring 3 is set between vibration damper plate 2 and sound panel 1, vibration damper plate 2 upper surface arranges blind hole 4, and damping spring 3 is placed in blind hole 4.
In the present embodiment, device is by snubber block, damping spring, sound panel forms, wherein lay sound panel bottom dry-type transformer and the iron core of this sound panel energy sealing dry type transformer, thus reduce the noise of formula transformer, vibration damper plate upper surface arranges blind hole, damping spring is placed in blind hole, snubber block is made to keep surfacing by arranging blind hole and being placed in blind hole by damping spring, sound panel contacts with snubber block well, damping spring effectively can ensure the stability of its work in blind hole simultaneously, in the damping ensureing realize again under to the prerequisite of transformer stable support transformer, and this structure is simple, the harmful effect that the vibrations of transportation peripheral produce dry-type transformer can be fallen effectively, effectively can reduce the noise of dry-type transformer simultaneously, improve the comfort level of Field Force, solve the shock resistance vibration problems of transformer in the transportation of mobile substation.Improve the quality of product.
