Tubular wind power bus installation method and installation assembly

The invention discloses a tubular wind power bus installation method and assembly, and the method comprises the steps: selecting a plurality of tubular buses according to the height of a tower drum, and enabling the tubular buses to be installed in a frame in a parallel arrangement manner, and forming a to-be-installed tubular wind power bus installation assembly; the tubular wind power bus installation assembly is installed in the tower drum; tubular buses in the tubular wind power bus installation assembly are disassembled, and one of the tubular buses is lifted to a preset height to form an upper tubular bus; hoisting the other tubular wind power bus to a position in butt joint with the lower end of the upper tubular bus to form a lower tubular bus; and welding the butt joint of the upper tubular bus and the lower tubular bus. According to the invention, the tubular bus is installed in the frame and integrated to form the tubular wind power installation assembly, so that the whole tubular wind power instal
