Description

Bus duct convenient to maintain Technical Field The utility model belongs to the technical field of bus ducts, and particularly relates to a bus duct convenient to maintain. Background The bus duct is a closed metal device formed by copper and aluminum bus posts and is used for distributing large power to each element of the dispersion system. Increasingly, wires and cables have been replaced in the field of low-voltage indoor power transmission mains engineering. The existing bus duct is internally densely provided with a plurality of groups of insulating conductors, when a single conductor is damaged abnormally and needs to be replaced, the top cover at the top of the bus duct is generally opened, then the conductor is taken out, the top cover needs to be repeatedly disassembled and assembled in a mode, the operation is complicated, the distance between the bus duct and a ceiling is small, and the conductor is not easy to be disassembled and assembled vertically. Therefore, a bus duct with convenient maintenance is provided. Disclosure of Invention The utility model provides a bus duct with convenient maintenance, and aims to solve the problems. The embodiment of the utility model provides a bus duct convenient to maintain, which comprises a shell; five insulating partition boards arranged at the bottom of the inside of the outer shell at equal intervals, a first half clamping groove arranged on the outer side wall of the insulating partition board, an inner shell arranged in the inside of the outer shell and close to positions between adjacent insulating partition boards, a second half clamping groove arranged on the outer side wall of the inner shell and close to one side of the first half clamping groove, an embedded groove arranged at the bottom of the outer shell, a clamping strip penetrating groove arranged at the top of the embedded groove and close to positions below the first half clamping groove and the second half clamping groove, a supporting plate arranged at the position right below the embedded groove, an all-clamping strip welded at the top of the supporting plate, an inner groove arranged at the bottom of the outer shell and close to one side of the embedded groove, a plugboard sliding on the inner side wall of the inner groove, a spring arranged between the inner wall of one side of the inner groove and the outer wall of one side of the plugboard, a slot arranged on the outer wall of one side of the supporting plate, and a heat dissipation channel penetrating through the bottom of the outer shell, the insulating partition board and the bottom of the outer shell cover. Further, the shell, the insulating partition plate and the heat dissipation channel on the shell cover are overlapped in the vertical direction; Through adopting above-mentioned technical scheme, guarantee that the heat dissipation passageway is linked together, and then make the air flow in the heat dissipation passageway perpendicularly, realize the air water conservancy diversion, utilize the air flow to take away more heat, realize the heat dissipation to the bus duct.
