PURPOSE: A sealing structure of a bus duct is provided to prevent rainwater and harmful substances from flowing into a bus duct by inserting a silicon sealing material into the bus duct. CONSTITUTION: A sealing structure of a bus duct comprises a bus duct(D) for covering the outer surfaces of multiple bus bars. Upper flanges(1f,2f) and lower flanges(1F,2F) are symmetrically formed on the top and bottom ends of left and right plates(1,2) of the bus duct. The upper flanges have downward bent pieces(1a,2a), and the lower flanges have inward bent pieces(1c,2c). An upper plate(3) covers the upper flanges. Both ends of the upper plate have downward bent parts(3a,3c). The downward bent parts have inward bent pieces(3b,3d). A lower plate(4) is coupled to the lower flanges. Both ends of the lower plate have downward bent pieces(4a,4b). |
