Deicing device for transformer

The invention relates to a deicing device, in particular to a deicing device for a transformer. The problems that in the prior art, when workers conduct deicing operation through hot air, physical output is large, the deicing work efficiency is low, and the deicing effect is limited are solved. Steam is generated in the heating water tank, the preheating box generates hot air through the electric heating wire, the steam and the hot air are conveyed into the steam-gas mixing box and sprayed out through the spraying pipe, the frozen part of the transformer is melted through mixed airflow of the high-temperature steam and the hot air, and the deicing effect is improved; and compared with an independent hot air deicing mode, the effect is better, and meanwhile the deicing efficiency is improved. And the bias flow unit is installed at the outlet of the injection pipe, the angle between the bias flow plate and the axis of the injection pipe can be adjusted after the screw is unscrewed, then the injection angle of t
