Abstract
The utility model provides a noise-reducing energy-saving protective hood for a dry transformer. The noise-reducing energy-saving protective hood comprises a front wall, a rear wall, a left wall, a right wall, a top cover and a base, which are six sides. At least three of the sides are plate structures hermetically disposed inside a sealed frame. Each plate structure is composed of an upper board, a micro-perforated board and a lower board sequentially from top to bottom. The six sides are connected in a pin manner to form a closed inside space. Less noise is transmitted from the transformer to the surrounding by means of systematic solutions and by effective noise reduction techniques such as sound insulation, noise elimination and vibration damping; meanwhile, the problem of insulation distance in dampness is solved, and the noise can be discharged standardly.
