Abstract
The utility model relates to a silencing shell of a dry transformer. The silencing shell comprises a shell and a ceiling, wherein the shell consists of a framework and a steel plate; the bottom of the shell is provided with a pedestal; the top of the shell is provided with a ventilation opening; the lower part and the upper part of the steel plate are provided with air inlets respectively; the ceiling is herringbone and covers the top of the shell; and a radiating port is arranged between the ceiling and the shell. The silencing shell has the beneficial effects of simple structure, good ventilating and radiating effect and capabilities of effectively achieving a silencing purpose by arranging a sound insulation fabric layer in the shell and effectively preventing water drops from entering the transformer by virtue of the downward radiating opening.
Description
Technical field
The utility model relates to the transformer technology field, especially relates to a kind of dry-type transformer sound attenuation.
Background technology
Transformer is usually located on residential quarter basement or ground; because transformer internal power element constantly does work, the transformer distribute heat is higher, causes operation troubles or stopping accident in order to prevent that temperature from raising; offer louvre on the transformer outer cover, dispel the heat by natural draft.Yet due to the variation of external environment condition, dust or rainwater are easy to enter in transformer by ventilation hole, thereby cause the operating efficiency of transformer to reduce, and affect the useful life of transformer.
Therefore, a kind of simple in structure, the appearance that is used for dry-type transformer case of ventilation that can be good, radiating effect is necessary.
The utility model content
The utility model is to provide a kind of simple in structure for solving the problems of the technologies described above, ventilation that can be good, radiating effect be used for dry-type transformer case.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of dry-type transformer noise reduction shell, comprise housing and ceiling, described housing is comprised of skeleton and steel plate, bottom at described housing is provided with base, top at described housing is provided with ventilating opening, is respectively arranged with air inlet on bottom and the top of described steel plate, and described ceiling is " people " font, cover at the top of described housing, be provided with thermovent between described ceiling and described housing.
As preferred technical scheme, the inboard of described housing is provided with the sound-proof fabric layer.
As preferred technical scheme, described thermovent is under shed, enters in described housing to prevent rainwater.
As preferred technical scheme, also be provided with fan above described ventilating opening, to strengthen result of ventilating heat dissipation.
The beneficial effect that the utlity model has is: (1) is simple in structure, has good result of ventilating heat dissipation;
(2) be provided with the sound-proof fabric layer in housing, can effectively reach quiet purpose;
(3) thermovent under shed, prevents that effectively water droplet from entering in transformer.
