▎ 摘　　要

NOVELTY - The bus has closed bus main body composed of bus duct bottom shell (1) and bus duct cover (7) and two U-shaped side plates (2), and two U-shaped side plates are set between two ends of bus duct bottom shell and two ends of bus duct cover. The two top part of bus duct bottom shell, two ends of bottom of bus duct cover and opposite side of U-shaped side plate are inserted with lower flame retardant clapboard (14) and upper flame retardant clapboard. Two of top part of lower flame retardant clapboard and two upper flame retardant clapboard are provided with equidistantly distributed slot, and two slots is contact with insulating sleeve. The inner wall of insulating sleeve is covered with connecting plate (12). One side of two groups of connecting plate is provided with conductive plate located in closed bus main body, and opposite sides of two groups of conductive plates are provided with connector located at middle position of inner part of closed bus main body. USE - Enclosed bus with built-in graphene for distributing large power for each element of dispersion system used in high-rise buildings and large factory buildings. ADVANTAGE - The bus prevents heat from being in the closed bus duct in a long time, so that the radiating operation is carried out without using the metal heat conduction property of the bus duct. The bus avoids the problem that the inner temperature of bus duct is too high so that it is not sensitive and easy to be damage. The function of screw thread rod and the screw cap is convenient for assembling the whole sealed bus structure, thus providing the bus with convenient dismounting effect. The heat generated by the conductive plate is radiated by radiating honeycomb hole and radiating fin, thus avoiding heat for a long period of time in bus duct itself to perform heat dissipation operation. DESCRIPTION OF DRAWING(S) - The drawing shows a whole exploded view of an enclosed bus with built-in graphene. 1Bus duct bottom shell 2U-shaped side plate 7Bus duct cover 12Connecting plate 14Lower flame retardant clapboard
