Abstract
The utility model relates to a dry -type transformer cabinet sound insulation muffler plate, including the inlayer, it is outer, noise damping layer sets up between inlayer and the skin for the denoising sound disappears, and inhale the sound wedge, set up the surface of inlayer for absorb the noise. The beneficial effects are that: simple structure sets up web frame between inlayer and skin, strengthen the compressive strength of plate body, adopt the inner plating setting to inhale the sound wedge, improved absorbing effect.
Description
Technical field
The utility model relates to technical field of transformer equipment, especially relates to dry-type transformer cabinet sound insulation muffler plate.
Background technology
Transformer is usually located on community basement or ground, and its noise life rest environment to surrounding resident running generation round the clock causes considerable influence, along with the strengthening gradually of national environmental consciousness, has just become requisite thing to the control of transformer noise.
Current solution mainly arranges sound-absorbing material on body of wall, although can solve noise problem preferably, its long construction period, expense are large; in addition at transformer by after airtight; reduce ventilation effect more, easily cause temperature to raise, cause operation troubles or stopping accident.
Therefore, one is applicable to transformer cabinet, can the appearance of the effective transformer case sound insulation noise elimination composite panel of noise reduction necessary
Utility model content
The utility model, for solving the problems of the technologies described above, is to provide one to be applicable to transformer cabinet, can the dry-type transformer cabinet sound insulation muffler plate of effective noise reduction.
The technical problem that the utility model solves realizes by the following technical solutions:
Dry-type transformer cabinet sound insulation muffler plate, comprising:
Internal layer;
Outer;
Noise reduction layer, is arranged between described internal layer and skin, in order to abate the noise; And
Sound absorption wedge, is arranged on the surface of described internal layer, in order to absorb noise.
As preferred technical scheme, between described internal layer and skin, be also provided with web frame, described web frame is netted, to strengthen intensity.
As preferred technical scheme, described web frame is netted.
As preferred technical scheme, described internal layer and described skin are the galvanized steel plain sheet of 1-3mm thickness.
As preferred technical scheme, described noise reduction layer is by the acoustical cotton of 30-40mm thickness and form for 3mm extrudes open-celled structure PE Material cladding with iron oxide foaming.
As preferred technical scheme, described internal layer is distributed with numerous perforation, to strengthen sound-absorbing effect.
The beneficial effect that the utility model has is: (1) structure is simple, between internal layer and skin, arrange web frame, strengthens the compression strength of plate body;
(2) adopt inner plating that sound absorption wedge is set, improve the effect absorbing noise.
Accompanying drawing explanation
Fig. 1 is the utility model: the structural representation of dry-type transformer cabinet sound insulation muffler plate;
Wherein: 1-internal layer, 2-noise reduction layer, 3-skin, 4-web frame, 5-perforation.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
With reference to shown in Fig. 1, dry-type transformer cabinet sound insulation muffler plate, comprises internal layer 1, noise reduction layer 2, web frame 4 and outer 3, wherein, described noise reduction layer 2 and web frame 4 are arranged between internal layer 1 and outer 3, be provided with sound absorption wedge 6, effectively intercepted the transmission of part low frequency source of sound on the surface of internal layer 1.
Internal layer 1 in the utility model and outer 3 is the galvanized steel plain sheet of 1-3mm thickness, noise reduction layer 2 is that open-celled structure PE material composition is extruded in the acoustical cotton of 30-40mm thickness and iron oxide foaming, wherein, silencing cotton is new chemical material, utilize chemical composition absorption portion low-and high-frequency noise, to strengthen sound-absorbing effect, internal layer 1 is distributed with numerous perforation 5, absorbs by physical principle the high frequency noise that transformer sends.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
