Protective device for high-low voltage transformation of machine room

The protective device comprises a U-shaped mounting frame distributed in the left-right direction, a base and walking wheels, and first telescopic push rods, a connecting frame and a flexible protective cover are vertically arranged at the four corners of the bottom wall of the top of the mounting frame correspondingly. The top of the mounting rack is also provided with a telescopic movable protection module used for dedusting and cooling the high-low voltage cabinet. According to the protective device for high-low pressure transformation of the machine room, powder scraps and crushed aggregates generated in the transformation machining process can be prevented from escaping into air through the cover type protective structure to pollute the environment, and the powder scraps and crushed aggregates generated in the transformation machining process can be cleaned through the movable dust removal structure, so that the dust removal efficiency is improved. And dual protection treatment of dust prevention and hig
