Fireproof device of electrical equipment

Abstract

The invention discloses a fireproof device of electrical equipment. The fireproof device comprises a box body, wherein a heat insulting plate is fixed to the outer wall of the box body, a mounting groove is formed in the box wall of the box body, a heat insulating net is fixed to the inner wall of the mounting groove, fine sand fills the inner wall of the mounting groove, asbestos are fixed to theinner wall of the box body, an exhaust hole is formed in the center position of the top of the box body, an exhaust pipe is fixed to the inner wall of the exhaust hole, and a suction pump is connected to the top end of the exhaust pipe. By using the heat insulating plate, the heat insulating net, the fine sand and the asbestos, the fireproof device not only plays a role of blocking a fire source,but also prevents a burnthrough phenomenon of the box wall of the box body. By using a water pump, a water tank and a high pressure spray head to extinguish a fire source, the equipment is preventedfrom being damaged again. By using an electrical motor, a bidirectional threaded rod and a sealing door, the box body can be sealed when a fire happens, and meanwhile, vacuumizing is carried out directly by means of the exhaust pipe and the suction pump, combustible gas is blocked and extracted to achieve a fire-extinguishing effect.

Description

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...

Problems solved by technology

However, after the electrical equipment catches fire, even if the circuit is disconnected, the electrical equipment is still in a burning state before the electric staff takes fire-fighting measures, which will not only seriously damage the internal electrical components of the electrical equipment, but also easily ignite objects near the electrical equipment, causing Larger range of fires, greater safety hazards
