Description

Flame-retardant power distribution cabinet Technical Field The invention relates to the technical field of electric appliances, in particular to a power distribution cabinet. Background The switch board includes the switch board body, the switch board body in have the cabinet chamber, install the mounting panel in the cabinet intracavity, install electrical apparatus on the mounting panel, electrical apparatus such as can be circuit breaker, mutual-inductor, various instruments, cable etc. the switch board body include the front gate again to install the cabinet door in gate department, in use, these electrical apparatus can take place to burn sometimes, burn and take place continuously, can cause bigger loss. The patent document with the publication number of CN216750895U discloses a flame-retardant power distribution cabinet, which utilizes the fact that when the interior of the cabinet body burns, the temperature of a heat-sensitive wire rises to the starting temperature of a sensing switch, so that the connected temperature sensing switch is started, an electric telescopic rod is controlled to extend out, a partition plate is controlled to move downwards, a plurality of radiating holes at the bottom of the cabinet body are sealed through the partition plate, the interior of the cabinet body is in a sealed state, meanwhile, the temperature sensing switch controls a fan to reversely rotate, air in the interior of the cabinet body is pumped out, the air in the cabinet body is reduced, the oxygen content in the air is reduced, the combustion improver in three elements of burning disappears, and the condition of burning cannot be achieved, so that flame retardance and fire extinguishment are carried out. The flame-retardant power distribution cabinet has the defect of low flame retardant speed, and cannot meet the requirements of rapid fire extinguishment. Disclosure of Invention The invention aims at overcoming the defects and providing the flame-retardant power distribution cabinet which can extinguish fire more rapidly and can meet some fire-extinguishing requirements. The technical scheme of the invention is realized in such a way that the flame-retardant power distribution cabinet comprises a power distribution cabinet body, wherein a cabinet cavity is formed in the power distribution cabinet body, a mounting plate is arranged in the cabinet cavity, an electric appliance is also mounted on the mounting plate, the power distribution cabinet body further comprises a front door, and a cabinet door is mounted at the door; the fire extinguishing device is characterized in that the fire extinguishing device is arranged on the inner side of a cabinet door and comprises a containing box, a connecting part is arranged on the back surface of the containing box, flame-retardant cotton is arranged in a containing cavity, the flame-retardant cotton is coated outside the containing cavity by a flammable material layer, the periphery of the flammable material layer is fixed on the containing box, the flame-retardant cotton is in a storage state under the condition that the flammable material layer is coated, when the flame-retardant cotton is not bound by the flammable material layer, the flame-retardant cotton is in an expansion state outside the containing cavity, one surface of the flame-retardant cotton, which is far away from the containing cavity, moves outwards for a certain distance, and a layer of fire extinguishing powder is arranged between the flame-retardant cotton and the flammable material layer. Further, the flame-retardant cotton being in an accumulated state means that a compressed spring is arranged in the accommodating cavity, and the spring supports the flame-retardant cotton. Further, the flame-retardant cotton being in the storage state refers to the state that the flame-retardant cotton is in the wrapping and tightening state of the inflammable material layer. Furthermore, the flame-retardant cotton can also form a convex structure around and a concave structure in the middle under the expansion state, and the concave structure covers the electric appliance. Further, a top plate is arranged between the spring and the flame-retardant cotton. Further, the fire extinguishing device is multiple, and the multiple fire extinguishing devices face different electric appliances. The power distribution cabinet has the advantages that the power distribution cabinet has quicker fire extinguishment and can meet some fire extinguishment requirements.
