Description
Technical field transmission & distribution are exchanged work journey.
The voltage of the certain grade of background technology, have certain economic electric transmission distance, exceed this distance, line drop is excessive, and line loss increases, and power transmission efficiency reduces; Therefore economic electric transmission distance can not expand along with the expansion of city scope, so just makes the transformer station at some power distribution network center have to be in city neighborhood, sometimes or even densely populated residential block.The thing followed is the noise of various equipment in transformer station, and the magnetic hysteresis as transformer is stretched noise, and cooling oil pump, fan running noise, for the interference of people's living environment.Noise disturbs residents becomes the livable environment problem that urban industry produces solution of having to, becomes the component content of built environment friendly society.The substation transformer room of residential block, position place needs to take noise reduction measure.
The double-deck silencer wall in utility model content transformer room, the technical problem that solve is: the noise that abatement transformer produces.
The double-deck silencer wall in transformer room, be a kind of be arranged on indoor former metope screen work and the extra play that combines of acoustical panel, be made up of interior screen work, interior acoustical panel, outer screen work, outer acoustical panel, dowel bar.Interior screen work expansion bolt is installed in former metope.Interior acoustical panel is installed on interior screen work.Outer screen work is installed on interior screen work across interior acoustical panel.Outer acoustical panel is installed on outer screen work.The splicing seams dowel bar of outer acoustical panel is reinforced and is beautified.Uniform micropore on interior acoustical panel, outer acoustical panel.When transformer noise ripple is by these micropores, according to fluid dynamics, fluid all significantly to be decayed its energy by the unexpected folding and unfolding in cross section; After outer acoustical panel micropore, through the transformer noise that outer acoustical panel is decayed first, the outer silencing cavity roundtrip between the outer acoustical panel of interior acoustical panel, is decayed again.Through the transformer noise of again decaying, during through interior acoustical panel, after the 3rd decay of the micropore on it, enter the interior silencing cavity roundtrip between the former metope of interior acoustical panel and transformer room, decayed by the 4th.Noise in transformer room, through 4 decay, noise reduction is remarkable.
During installing, be more noise reduction, first draw track in former metope cement mortar bottoming brooming.Then, on former metope, be fixedly mounted with interior screen work, interior acoustical panel, outer screen work, outer acoustical panel, dowel bar successively, dress up double-deck silencer wall.
The double-deck silencer wall in transformer room of the application, is the noise installing the generation of two-layer silencer wall abatement transformer on former metope, it is characterized in that: double-deck silencer wall is made up of interior acoustical panel, interior screen work, outer acoustical panel, outer screen work, dowel bar; Interior screen work expansion bolt is installed in former metope; Interior acoustical panel is installed on interior screen work; Outer screen work is installed on interior screen work across interior acoustical panel; Outer acoustical panel is installed on outer screen work; The splicing seams dowel bar of outer acoustical panel is reinforced and is beautified;

Transformer room's metope has the thick additive dedicated mortar of 3mm or special interface agent together, and described additive dedicated mortar is used for bottoming and rough through scraping, and described special interface agent is through getting rid of hair; Outside described additive dedicated mortar or special interface agent, have thick 1: 1: the 6 cement gypsum mortar of 8mm, described cement gypsum mortar is used for bottoming, through brooming or mark track; One plain-water slurry is had outside described cement gypsum mortar; Build above-mentioned interior screen work, interior acoustical panel, outer screen work, outer acoustical panel outside described plain-water slurry, acoustical panel splicing seams dowel bar is reinforced and is beautified; Described interior screen work uses 50 × 50 square steel tube keel, and be built into cavity and sound absorption trap, outer screen work uses 30 × 30 square steel tube keel, is built into cavity and sound absorption trap; Inside and outside acoustical panel all uses Helmholz resonance structure coloured silk plating acoustical panel, is fixed on inside and outside screen work respectively with pulling rivet.
Further, interior acoustical panel Helmholz resonance structure coloured silk plating acoustical panel, thickness of slab 0.8mm, high 1m, wide 0.5m, be fixed on interior screen work with pulling rivet, 10 pieces of silencer walls being spliced into height 10m.
Further, outer acoustical panel Helmholz resonance structure coloured silk plating acoustical panel, thickness of slab 0.8mm, high 1m, wide 0.5m, be fixed on outer screen work with pulling rivet, 10 pieces of silencer walls being spliced into height 10m.
Further, interior screen work 50 × 50 square steel tubes do keel, in latticed interconnected, adopt connector to be connected, keel centreline spacing 1m, the expansion bolt spacing 400mm of fixing keel.
Further, outer screen work 30 × 30 square steel tubes do keel, in latticed interconnected, adopt connector to be connected, keel centreline spacing 1m, the expansion bolt spacing 400mm of fixing keel.
Further, silencer wall bottom is connected with ground connection built-in fitting, doublely does barricade.
The beneficial effect of the double-deck silencer wall in transformer room is: 1, noise reduction is obvious, and the transformer room of 220kV transformer station can noise reduction 8dB, and noise reduction is up to standard.2, simple.3, have electromagnetic shielding action, the electromagnetic field inducing intensity outside transformer room obviously weakens.4, decoration is had to act on.
