According to a further development of the invention, the flat holes are horizontal holes.
According to a further improvement of the invention, the flat holes are vertical holes.
A further development of the invention provides that the air inlet is formed by a lower hood wall from which the outer hood is removed.
In a further improvement of the invention, a protective net is arranged in the air inlet.
The composite air inlet box comprises the sound absorption block. The sound absorption block is provided with flat holes which are parallel to each other, and an outer cover and an inner cover are respectively arranged on the outer surface and the inner surface of the sound absorption block. The vertical edge and the upper edge of the opening of the outer cover are connected with the corresponding edges of the sound absorption blocks, and an air inlet which is convenient for natural wind to enter is arranged between the lower edge of the opening of the outer cover and the sound absorption blocks. Four corners of the opening of the inner cover are connected with four corners of the sound absorption block by short pipes, so that a space is reserved between the opening of the inner cover and the sound absorption block. The inner cover is internally provided with a gas-collecting guide ring, one end of the gas-collecting guide ring is connected with the sound absorption block, and the flat holes are all positioned in the gas-collecting guide ring. When the sound absorption block works, external natural wind enters the outer cover from the air inlet, sequentially passes through the flat holes on the sound absorption block and the check ring under the action of the guide plate, and then enters the inner cover from the periphery of the outer end of the check ring. Then, the air flows to the periphery of the inner cover under the blocking of the inner cover, and is discharged from the space between the inner cover and the periphery of the sound absorption block to enter the main transformer chamber. Thereby realizing ventilation and heat dissipation of the main transformer chamber. And because the materials used for the sound absorption block, the outer cover and the inner cover are all glass wool boards, the sound absorption block, the outer cover and the inner cover have sound insulation and sound absorption functions, and noise generated by natural wind flowing through the sound absorption block, the outer cover and the inner cover can be reduced. The invention has the functions of ventilation and heat dissipation, noise reduction and complete functions. And the noise reducing function can reduce the outward spreading of the noise generated in the operation process of the main transformer through the louver, thereby being beneficial to the health and normal life of surrounding residents.
