Noise control device of power transformer

The utility model relates to the field of transformer noise control, in particular to a power transformer noise control device which comprises a mounting base, a ventilation support is fixedly connected to the top of the mounting base, a fan is fixedly connected to the bottom of the inner wall of the ventilation support, and a power transformer is fixedly connected to the top of the ventilation support. According to the anti-noise device for the power transformer, dust and other sundries can be isolated outside the power transformer through the arrangement of the dustproof cover, the waterproof and dustproof effects are achieved, meanwhile, through cooperation of an end face gear, a transmission gear shaft and an end face gear ring, two dust removal brushes and a scraping rod conduct regular dust removal on the surface of the dustproof cover, manual cleaning is not needed, the labor intensity is reduced, and meanwhile the working efficiency is improved. The power transformer is simple in structure, the servic
