technical field
[0001] The invention relates to the technical field of fire protection devices for electrical equipment, in particular to a fire protection device for electrical equipment. Background technique
[0002] Fires caused by rotted power distribution cabinets, aging lines, short-circuited equipment, and improper operation of electrical equipment are the most common in enterprises. The main reason is that the power protection equipment does not play a good protective role, and cannot effectively protect the equipment and control the fire source caused by it when an electrical short circuit occurs. Generally, metal power distribution cabinets are easy to short-circuit and cause fires after the aging of electrical equipment. Poor sealing facilities will also cause dust and water to enter the interior of the power cabinet, causing accelerated aging of internal components. Non-metallic waterproof, dustproof, fireproof and anti-corrosion distribution boxes play a good r...
