The hot air outlet position is located below the scraper plate to dry the surface of the transformer body after cleaning. The cold air outlet position is located below the hot air outlet position to cool the surface of the transformer body after drying to prevent the temperature residue from drying from affecting the subsequent temperature detection of the transformer body surface.

[0028] Compared with the prior art, the present invention has the following beneficial effects:
