Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to a dust removal electrical cabinet. Background Art

[0002] An electrical cabinet is a carrier used to install and protect electrical equipment. It is usually made of metal materials and has dustproof, waterproof, corrosion-resistant, explosion-proof and other properties. It can also withstand a certain degree of mechanical shock and vibration. Electrical cabinets are widely used in industrial production and public facilities. They can be used to install transformers, switches, controllers, computer equipment and other electrical equipment. Electrical equipment running inside the electrical cabinet will generate electromagnetic radiation and heat. These factors will cause tiny particles in the air to accumulate on the surface or inside the equipment, reducing the service life and reliability of the electrical equipment.
