Between the import of machine, the outlet of box type fan between the import of outer plenum chamber, between the outlet of outer plenum chamber and the import of silencer
Link together.
Further improvement of the present invention scheme is to be connected with the first reducing between the outlet of box type fan and the import of outer plenum chamber
Pipe, the big end and small end of the first reducer pipe are connected with the outlet of box type fan and the import of outer plenum chamber respectively.
Further improvement of the present invention scheme is that first reducer pipe is made of intermediate layer, internal layer and outer layer, in described
Interbed is block of glass wool, and internal layer is punching steel plate, and outer layer is steel plate.
Further improvement of the present invention scheme is that have bend pipe, the second reducer pipe between outer plenum chamber and silencer successively, described
The small end and big end of second reducer pipe are connected with bend pipe outer end and muffler inlet respectively.
Further improvement of the present invention scheme is that the bend pipe, the second reducer pipe are by intermediate layer, internal layer and outer layer structure
Into the intermediate layer is block of glass wool, and internal layer is punching steel plate, and outer layer is steel plate.
Further improvement of the present invention scheme is that the box type fan has two, and the interior plenum chamber and outer plenum chamber are equal
For two, the outlet of interior plenum chamber and the import of outer plenum chamber are two, two outlets of interior plenum chamber respectively with a case
The import of formula wind turbine is connected, and the outlet of two box type fans is connected with an import of outer plenum chamber respectively.
Further improvement of the present invention scheme is that the inlet tube, interior plenum chamber, outer plenum chamber are by intermediate layer, internal layer
Formed with outer layer, the intermediate layer is block of glass wool, and internal layer is punching steel plate, and outer layer is steel plate.
Further improvement of the present invention scheme is that the wind turbine that the box type fan contains in shell and shell is formed, described
Shell is made of intermediate layer, internal layer and outer layer, and the intermediate layer is block of glass wool, and internal layer is punching steel plate, and outer layer is steel plate.
Further improvement of the present invention scheme is that the silencer contains housing, and the housing is tubular, and its one end has company
Acting flange, it is characterised in that have at least two compound anechoic sheets in housing.
As can be seen from the above scheme, due to the invention reside in the outer end of inlet tube have successively interior plenum chamber, box type fan,
Outer plenum chamber and silencer, under box type fan effect, pass through interior plenum chamber and outer static pressure from the air velocity of inlet tube discharge
Reduced after case since the cavity volume of interior plenum chamber and outer plenum chamber increases so that the noise molecular energy that air-flow is propagated is able to
Decay.Again due to being provided with silencer after outer plenum chamber, ensureing that main transformer room can cool down, eliminates safe hidden trouble
Under the premise of, the noise for discharging air-flow is further reduced, so as to eliminate the healthy and normal life to resident near substation
The influence living brought.
