Abstract
The invention relates to a fireproof anticorrosion cable tray and a processing technology thereof, and belongs to the technical field of distribution equipment. The fireproof anticorrosion cable traycomprises a box, a box cover, an extinguishing device and a heat radiation device, the upper and lower surfaces of the box cover are provided with first and second smoke sensors respectively, and theheat radiation device is arranged in the sidewall of the box; the fire extinguishing device comprises a carbon dioxide gas cylinder, an internal nozzle and external nozzles, the internal nozzle is arranged in the inner sidewall of the box, the external nozzles are arranged over the box cover, and a carbon dioxide gas cylinder is communicated with the internal and external nozzles via a pipeline; and the heat radiation device comprise a silica gel heat conducting sheet, a first heat conducting plate and a second heat conducting plate, and one side surface of the second heating conducting plateis provided with metal radiating fin. Due to cooperation among the first smoke sensor, the second smoke sensor and the extinguishing device, the fireproof anticorrosion cable tray can extinguish fireactively, and the fireproof anticorrosion cable tray is much safer.
Description
technical field [0001] The invention relates to a fire-resistant and anti-corrosion cable groove box and a processing technology thereof, belonging to the technical field of power distribution equipment. Background technique [0002] The cable trough box is a trough box used to place cables in the fire protection system. Since cables are flammable, cable fires caused by spontaneous combustion of cables or other reasons occur from time to time, and the conductivity of cables will make the fire It quickly spread to every corner and caused a wide range of hazards. The use of fire-resistant cable tray boxes can effectively reduce the incidence of fire, control the spread of fire, and reduce fire damage. [0003] At present, the refractory trough box (also called refractory bridge) on the market is mainly composed of metal skeleton and glass fiber reinforced material, composite fireproof board of inorganic materials, refractory aluminum silicate wool felt and fireproof base foam ...
