Description

Noise insulation cabinet for transformer

Technical Field

The utility model relates to a transformer separates noise cabinet belongs to the power equipment field.

Background

In recent years, urban noise pollution has become the third major public nuisance next to air pollution and water pollution, and box-type transformers and dry-type transformers are indispensable power equipment in urban construction, and the equipment is widely used in urban construction, such as various districts, villas, nursing homes, and the like.

However, in the prior art, various noise reduction materials are filled in the cabinet to achieve a good noise reduction effect, heat in the cabinet is not easy to dissipate due to the fact that the cabinet is easy to bring, and the heat dissipation effect is influenced to a certain extent.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a transformer separates noise cabinet to solve current problem.

In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides a transformer separates cabinet of making an uproar, its structure includes installing support, cabinet door, falls the hole of making an uproar, the cabinet body, cabinet door and cabinet body hinged joint, installing support and cabinet body fixed connection, it is equipped with a plurality of and evenly lies in cabinet body side face and top surface to fall the hole of making an uproar, it is equipped with the annular arch of circle on cylindric and its inner wall to fall the hole of making an uproar, protruding align to grid is falling the downthehole wall of making an uproar, it has the annular amortization of circle cotton to fill on.

Furthermore, the upper end and the lower end of the cabinet body are welded with mounting brackets, the mounting brackets at the lower ends are also provided with inverted-shaped fixing grooves, and the mounting brackets and the fixing grooves are provided with notches for mounting and fixing.

Furthermore, the top of the inner wall of the cabinet body is fixedly provided with a limit groove made of concave metal materials, the opening of the limit groove is downward, and the bottom of the inner wall of the cabinet body is flatly paved with a silencing cotton pad.

Further, the silencing cotton pad is mounted on the cabinet body through bolts.

Furthermore, the silencing cotton is made of polyurethane sponge, and the material is high in temperature resistance and good in silencing effect.

Furthermore, the sound attenuation cotton pad is made of polyurethane foam plastics, and the materials have excellent elasticity, flexibility, elongation and compression strength; the chemical stability is good.

The utility model has the advantages that: according to the invention, through the unique noise reduction holes, the noise in the cabinet is suppressed to a certain degree, and the heat dissipation effect is not influenced.

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

fig. 1 is a schematic structural view of a transformer noise-insulation cabinet of the present invention;

fig. 2 is the utility model relates to a transformer separates the structure schematic diagram in hole of making an uproar falls in cabinet body machine of making an uproar.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 and 2, the present invention provides a technical solution of a noise-proof cabinet for a transformer: the structure of the noise reduction cabinet comprises a mounting bracket 1, a cabinet door 2, noise reduction holes 3 and a cabinet body 4, wherein the cabinet door 2 is hinged with the cabinet body 4, the mounting bracket 1 is fixedly connected with the cabinet body 4, the noise reduction holes 3 are provided with a plurality of circular-ring-shaped bulges 31 which are uniformly arranged on the side surface and the top surface of the cabinet body 4, the noise reduction holes 3 are cylindrical, the inner walls of the noise reduction holes 3 are provided with circular-ring-shaped noise reduction cotton 32, the inner corners of the bulges 31 are filled with the circular-ring-shaped noise reduction cotton 32, the mounting bracket 1 is welded at the upper end and the lower end of the cabinet body 4, a fixing groove 11 of a reversed shape is also arranged on the mounting bracket 1 at the lower end, notches for mounting and fixing are respectively arranged on the mounting bracket 1 and the fixing groove 11, a limiting groove 41 made of a concave-shaped metal material is fixedly arranged at the top of the inner wall of the cabinet body 4, the, the silencing cotton pad 42 is mounted on the cabinet body 4 through bolts, the silencing cotton 32 is made of polyurethane sponge, the material is high-temperature-resistant and has a good silencing effect, and the silencing cotton pad 42 is made of polyurethane foam plastic and has excellent elasticity, flexibility, elongation and compression strength; the chemical stability is good.

For example, transformer and relevant subassembly will be installed on the cotton pad 42 of amortization and the spacing groove 41 of cabinet body 4 inside, the cotton pad 42 of amortization helps reducing because of the produced noise of device vibration, thereby it makes an uproar to fall the arch 31 on the hole 3 of making an uproar will effectively refract the noise, and the cotton 32 of amortization at protruding 31 interior angle will also inhale it, can play the effect that slows down the vibration to arch 31 simultaneously, enlarge the effect of making an uproar of arch 31, simultaneously because arch 31 is for having the space around installation its middle part, thereby make natural wind or the fan of installing additional take away the heat in can the better entering cabinet.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
