Then transformer noise problem just highlights.Transformer noise problem has become resident's focus of attention.Transformer is made an uproar
Although loudness of a sound degree will not cause people's life danger, the health of people can be endangered, and influence the normal operation of controller switching equipment.It is high
Mostly using dry-type transformer, noise belongs to the noise of low decibel, generates in most cases in the underground distribution room of layer house
Low frequency noise can generate chronic injury to human body, low frequency noise easily make one irritability, agitation, even lose one's marbles sometimes, long
Phase is invaded and harassed by noise, it may appear that the symptoms such as headache, otalgia dreaminess, failure of memory, malaise, can also cause neurasthenia,
The nervous system diseases such as insomnia.
Country《Code for design of dwelling houses》Middle regulation：Boiler, transformer should not be arranged in residential housing and other has noise to shake
The device rooms such as dynamic source.As it is subject to conditions need arrangement when, existing building fire protection, Sound insulation for building and related specifications should be met
Regulation.《Code for sound insulation design of civil buildings》Regulation：When condition is permitted, noise source is easily arranged on underground, but unsuitable neighbour
Main building is located under main building.During if not being avoided that, it is necessary to take reliable vibration isolation, sound insulation measure.According to《Chinese
People republic standard of environmental noise of urban area》, it is specified that the ambient noise highest limit value in five class region of city.It lives and belongs to two classes
The suitable application region of standard：60dB, night 50dB between daytime.
Utility model content
The utility model aims to solve the problem that the above problem, provides a kind of knot for reducing dry-type transformer operation noise
The features such as structure, the utility model Installation Flexibility is big, stability is good, vibration-isolating effect is notable, it can be directly mounted at transformer cabinet
On pedestal more particularly to when installing, the utility model is equipped with itself fixed structure, so can be by the utility model itself during installation
It first fixes, is brought conveniently to installation.The technical solution of the utility model is as follows：
A kind of structure for reducing dry-type transformer operation noise, including upper steel plate, lower steel plate, two upper coverboards, two
A lower coverboard, positioning plate and four springs, edge of the upper surface equipped with upper rubber pad, upper steel plate lower surface both ends of upper steel plate
Retainer ring A is respectively equipped with, the lower surface of lower steel plate is equipped with lower rubber pad, the edge at lower steel plate upper surface both ends is respectively equipped with admittedly
Determine ring B, dismountable fixed band is equipped between retainer ring A and retainer ring B, is joined between lower steel plate and positioning plate by four springs
It connects, is coupled between upper steel plate and positioning plate by four Level tune nuts, each Level tune nut exists with corresponding spring
On same axis, upper coverboard is fixed on the both ends of upper steel plate lower surface, and lower coverboard is fixed on the both ends of lower steel plate upper surface, two
The inside of lower coverboard is equipped with rubber brush.
In use, being compressed the spring into using fixed band, retainer ring A and retainer ring B minimum, the utility model itself is consolidated
After fixed, the utility model is fixed on the pedestal of dry-type transformer cabinet using attachment bolt, for reducing noise.
Based on the above technical solution, positioning plate is equipped with level meter, preferably air-bubble level, for detecting this
Whether utility model is in horizontality.
Based on the above technical solution, lower steel plate is equipped with bolt fixing hole, for the utility model to be fixed on
On other substrates.
Based on the above technical solution, the upper surface of lower steel plate is equipped with rubber heelpiece, during for reducing spring-compressed
Noise.
Based on the above technical solution, the upper steel plate, lower steel plate and positioning plate are rectangle, this structure is just
In on dry-type transformer bottom base of cabinet body, and it is strong to install rear stability.
The utility model has the following advantages that：
The utility model can effectively reduce the noise generated during dry-type transformer operation, and the utility model installation side
Just, stability is strong.
