Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described in detail:
The directed air cooling system of this New forced is made up of casing, axial-flow centrifugal fan 1, oil-filled transformer 6, and casing comprises lamp box 12, emitting underground transformer case 5; Be manufactured with passage between lamp box 12 and emitting underground transformer case 5, lamp box 12 panel lower surface is provided with horizontal shutter shrouding 8; Dividing plate 7 bottom lamp box 12 is lifted with axial-flow centrifugal fan 1, and the air inlet of axial-flow centrifugal fan 1 is near horizontal shutter shrouding 8; Emitting underground transformer case 5 top is provided with cover plate 11, and emitting underground transformer case 5 outer surface is provided with vertical louvres window shrouding 10, and the corner of emitting underground transformer case 5 is symmetrically installed with limiting square steels 9;
Be provided with oil-filled transformer 6 by I-steel in emitting underground transformer case 5, be provided with the directed tuyere 3 in air channel under oil-filled transformer 6 fin by location, air channel bent plate 4, the directed tuyere 3 in air channel is connected by blower fan special air duct 2 with between axial-flow centrifugal fan 1; The air outlet of axial-flow centrifugal fan 1 is mutually vertical with the directed tuyere 3 in air channel.(see accompanying drawing 1 ~ 5)
Axial-flow centrifugal fan 1 is arranged on lamp box dividing plate 7 lower end by the directed air cooling system of this New forced, the close also parallel transverse shutter shrouding 8 of air inlet of axial-flow centrifugal fan 1.The directed tuyere 3 in air channel is riveted in emitting underground transformer case 5 by location, air channel bent plate 4, the directed tuyere 3 in air channel is arranged on below the fin of oil-filled transformer 6, the wind mouth mouth bending and molding of the directed tuyere 3 in air channel is 44 °, can ensure that fresh cold air is under the effect of axial-flow centrifugal fan 1, accomplish zero windage loss by blower fan specialty air channel 2.
The cold air that directed tuyere 3 flows out from air channel is through the heating fin of oil-filled transformer 6, and hot-air distributes from horizontal shutter shrouding 8 with air-flow; Axial-flow centrifugal fan 1 increases air outlet convection fan, defines the directed flow of wind circulation, and decreases noise pollution.Limiting square steels 9 is welded on the surrounding of emitting underground transformer case 5, effectively ensures that the vertical louvres window shrouding 10 of emitting underground transformer case 5 is repeatedly indeformable through bending.
