Abstract
The invention discloses a noise reduction device for a dry-type transformer, which comprises a galvanized acoustic baffle, wherein the galvanized acoustic baffle is mounted in an inner cavity of the dry-type transformer in a matching manner; and a plurality of sound wave holes are uniformly formed in the galvanized acoustic baffle. The noise reduction device is simple in structure, low in cost and good in noise reduction effect, and has the advantages of convenience and flexibility in mounting, simplicity in manufacturing, economy and practicability.
Description
Technical field
The invention belongs to technical field of transformer manufacturing, be specifically related to a kind of dry-type transformer denoising device.
Background technology
Along with the raising of people's environmental consciousness, the problem of noise pollution of transformer also highlights, and the noise of transformer is contaminated environment not only, and harm humans is healthy again.The mode of the transformer pressure-reducing that usually adopts now is to adopt by reducing the transformer core magnetic flux density mostly, reduces the noise that iron core produces, and this kind noise reduction mode can directly cause the increasing of transformer cost.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of simple in structure, dry-type transformer denoising device that the noise reduction cost is low is provided.
A kind of dry-type transformer denoising device comprises zinc-plated sound panel, and described zinc-plated sound panel coordinates and is arranged in the inner chamber of dry-type transformer, uniform several sound waves hole of offering on this zinc-plated sound panel.
The present invention is simple in structure, cheap, excellent noise reduction effect, and have easy for installation flexibly, make simple, economical and practical advantage.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples are only for explanation the present invention but not for limiting the scope of the invention.
Embodiment 1
Referring to Fig. 1, a kind of dry-type transformer denoising device provided by the invention comprises zinc-plated sound panel 1, and described zinc-plated sound panel 1 coordinates and is arranged in the inner chamber of dry-type transformer 2, uniform several sound waves hole 3 that offers on this zinc-plated sound panel 1.During operation, sound wave incides in this sound wave hole 3, can go deep into material internal along these spaces, with material generation rubbing action, acoustic energy is changed into heat energy, part acoustic energy is consumed, thereby arrives the effect of noise-reducing, effectively reduces the noise of dry-type transformer operation.
Claims (1)
1. dry-type transformer denoising device is characterized in that: comprise zinc-plated sound panel, described zinc-plated sound panel coordinates and is arranged in the inner chamber of dry-type transformer, uniform several sound waves hole of offering on this zinc-plated sound panel.
