On, it passes through connector and is assemblied on wall, is provided between low frequency absorption noise reducing plate to connector and wall installation position
Gap, the gap ensures there is rational resonating cativty between low frequency absorption noise reducing plate and wall.The denoising device structure of the patent
Complexity, substantial amounts of interlayer will be set in power transformation station domestic demand, increase the area of power transformation station, and the change in existing urban cells
Room typically requirement in power station is smaller, and the influence to community resident is built with less power transformation station.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of shielding denoising device for cell transformer station,
The utility model is connected by by screen layer with ground plane, while earthing effect and shield effectiveness are increased, and the utility model
Noise reduction Rotating fields it is simple, be easily installed or directly hang on wall.The technical solution of the utility model reduces shielding noise reduction
Plant construction land used, meets the demand of environment protection transformer station.
The technical solution adopted in the utility model is：A kind of shielding denoising device for cell transformer station, including power transformation
Stand wall, wire netting, metal foil, ground stud, noise reduction layer, wherein wall internal layer include wire netting, metal foil, it is characterised in that：
Described wire netting is connected with ground stud, and the iron wire with wire netting more is wrapped in ground stud outer layer, described ground stud it is buried enter
Greatly；Wall inner side is provided with noise reduction layer, and noise reduction layer is multiple lattice compositions, and each lattice includes copper sheet and elastic film, copper
Piece is pasted in elastic film outer layer, and described copper sheet is near transformer side.
Further, when described wall is manufactured, wire netting is first established, metal foil is fixed on iron wire with conductive body
On the net.
Further, the side of shielding denoising device four for cell transformer station sets wall, and four sides wall is respectively provided with 4 and connects
Pile, the wire netting of 4 ground studs respectively with place wall is connected.
Further, described wire netting grid is 10cm.
Further, described lattice is made up of resin, and elastic film is silicon rubber elastic film, and elastic film thickness is
