Further improvement of the utility model scheme is, is had deflector in sound absorption block one side that outer cover covers.It is described to lead
The top of flowing plate is connected on the sound absorption block between that nethermost flat hole and air inlet, and the following of deflector tilts in upward
Shape is arranged.
The further improvement project of the utility model is that have the blast wall to fit together with it outside rack tube.
As can be seen from the above scheme, since the utility model contains the rack tube for surrounding main transformer from surrounding,
The upper end surrounding of the rack tube has introversion side so that the upper end bore of rack tube is less than the bore at other places.Rack tube
Soundproof door is arranged at barrel lower part, under the action of cylinder and soundproof door and multiple sound insulationg boards are led in support, makes to produce when 220KV transformer station high-voltage side bus
Raw noise has obtained larger decaying into external diffusion, communication process, to play mute, Noise Reduction.And due to
The inlet box for being provided on the barrel of soundproof door both sides and being interlinked to the outside in rack tube so that outside air enters the interior of rack tube
Bottom of chamber portion, then by the introversion side on rack tube top, free convection mechanism is constituted, make outside air and the air shape in support tube
At convection current cooling effect is played to which the heat in support tube to be discharged.So that 220KV transformers always work in properly
Temperature environment in, it is ensured that the reliability service of transformer.
