| titleOfInvention | Fire-retardant device of switch board with isolated air function |
| abstract | The invention discloses a flame retardant device of a power distribution cabinet with an air isolation function, which belongs to the technical field of electric power facilities and can realize that when a power distribution cabinet causes fire disaster due to water or overheating, a fire alarm is triggered, heat is transferred to a multilayer heat conduction plate and an arc-shaped heat transfer plate through a heat conduction connection block, the multilayer heat conduction plate is overheated to decompose sodium azide to generate nitrogen expansion, so that a corrugated flame retardant air bag extends downwards, external air is isolated to prevent combustion, the nitrogen generated by decomposition compresses a compression membrane, pore silica gel in the compression membrane extrudes and absorbs water around the power distribution cabinet to prevent water from diffusing and reduce electric shock danger caused by water, the arc-shaped heat transfer plate transfers heat to an air storage membrane, a conical air guide tube penetrates the air storage membrane to enable gas to overflow instantly, impact a storage ball to leave from an injection groove, and the storage ball is in contact with the power distribution, the released dry ice is sublimated to absorb heat when heated, and is changed into nonflammable carbon dioxide gas for inflaming retarding. |
