Abstract
The utility model relates to a denoise structure of a power transformer, which is used for denoising the power transformer. A box body radiator of the transformer is a sheet type radiator; and a box body of the transformer is provided with an interlayer. The denoise structure is characterized in that: the denoising structure comprises a sound-absorbing cover arranged in the interlayer of the transformer box body. The sound-absorbing cover is composed of a perforated sound-absorbing plate and a sound-insulation plate arranged at outer side of the perforated sound-absorbing plate. Through installing the sound-absorbing cover in the interlayer of the transformer box body, the noise of the transformer is reduced by 5 to 7 dB.
Description
Technical field
The utility model relates to electrical equipment technical field, more particularly, relates to the power transformer and the reactor of strap formula radiator.
Background technology
Power transformer is widely used in the city load center, along with people are more and more higher to the requirement of living environment, to the noise level of transformer also limit more and more stricter.But the restriction noise measure that existing transformer manufacturing process is taked adds rubber cushion, joint treatment unshakable in one's determination, casing as: device body bottom and does interlayer and irritate sand etc., and effect is all undesirable, generally only falls 2-3dB.
The utility model content
The technical problems to be solved in the utility model is that the defective at existing power transformer noise reduction measure weak effect provides a kind of new power transformer denoising structure.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of power transformer denoising structure, the noise reduction that is used for power transformer, the casing radiator of described transformer is a gilled radiator, the casing of described transformer has interlayer, it is characterized in that: described denoising structure comprises and is installed in the interbedded sound-absorbing cover of described casing, and described sound-absorbing cover is made up of perforation abatvoix and the sound insulationg board that is arranged on the described perforation abatvoix outside.
Wherein, preferred, be cavity between described perforation abatvoix and the described sound insulationg board.
Implement the technical solution of the utility model, have following beneficial effect:, can reduce noise of transformer and reach the 5-7 decibel by this denoising structure of installing between the transformer tank interlayer body.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
The transformer denoising structure general assembly schematic diagram that Fig. 1 provides for the utility model embodiment
The sound-absorbing cover structural representation that Fig. 2 provides for the utility model embodiment;
The perforation abatvoix structural representation that Fig. 3 provides for the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model embodiment provides a kind of power transformer denoising structure, as shown in Figure 1, comprising: transformer radiator 201, transformer tank interlayer body 202 is provided with sound-absorbing cover 240 in the described transformer tank interlayer body 202.By sound-absorbing cover 240 is set, this transformer greatly reduces noise, through actual measurement, can reduce the 5-7 decibel.
In specific embodiment, as shown in Figure 2, described sound-absorbing cover 240 comprises: be fixed on described transformer tank interlayer body 202 inboards perforation abatvoix 241, be arranged on the sound insulationg board 242 in described perforation abatvoix 241 outsides.Described sound insulationg board 242 usefulness acoustic materials are made, and play the sound insulation effect, and the noise that transformer is sent does not continue to transmit outward.Described perforation abatvoix 241 is made for sound-absorbing material, as shown in Figure 3, has hole 243 by certain size, makes acoustic energy assemble and dissipate.
In a preferred embodiment, be cavity 244 between described perforation abatvoix 241 and the described sound insulationg board 242.This cavity 244 and perforation abatvoix 241 be common to constitute the low-frequency resonance sound-absorbing structures, makes by the consumed energy that vibrates back and forth in cavity 244 of the noise behind the perforation abatvoix 241, does not transmit outward.
In the preferred embodiment, perforation abatvoix 241, sound insulationg board 242 are fixed on casing interlayer 202 inwalls, and keep cavity size not change.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
Claims (2)
1. power transformer denoising structure, the noise reduction that is used for power transformer, the casing radiator of described transformer is a gilled radiator, the casing of described transformer has interlayer, it is characterized in that: described denoising structure comprises and is installed in the interbedded sound-absorbing cover of described casing, and described sound-absorbing cover is made up of perforation abatvoix and the sound insulationg board that is arranged on the described perforation abatvoix outside.
2. power transformer denoising structure according to claim 1 is characterized in that, is cavity between described perforation abatvoix and the described sound insulationg board.
