Transformer fan and vibration isolation mounting seat structure thereof

The vibration isolation mounting seat structure comprises a cross flow fan, the cross flow fan comprises a shaded pole motor, a rotating part and a tail end rotating shaft, and the vibration isolation mounting seat structure further comprises a first vibration reduction assembly which is connected to the periphery of the rotating part in a sleeving mode and used for preventing the rotating part from surging; the first vibration reduction assembly comprises two supporting limiting rings fastened in the vibration reduction installation box shell, at least two guide shafts connected between the two supporting limiting rings and a wind breaking frame connected to the guide shafts in a sliding mode. Wherein the air breaking frame reciprocates along the guide shaft and is used for continuously cutting off the air inlet surface and the air outlet surface of the cross flow fan in the sliding process, so that air at the air inlet surface and the air outlet surface is separated. The invention further discloses the tran
