The utility model discloses a vertical tubular bus-bar connecting structure and a connecting fitting thereof for a converter station valve hall. The connecting structure includes a vertical tubular bus-bar, an upper tubular bus-bar clip hooping on the upper end of the vertical tubular bus-bar and a lower tubular bus-bar clip hooped on the lower end of the vertical tubular bus-bar. A suspension rod is axially and movably inserted in the upper tubular bus-bar clip which is provided with an annular stopping edge guidingly and slidingly fitted to the suspension rod. The upper end of the suspension rod is a hinged end which is hinged to a fixed conductor of the corresponding valve hall, and the upper end of the suspension rod penetrates through upwardly the upper end of the stopping edge. The lower end of the suspension rod is fixedly provided with a supporting and limiting device which is in stopping fit with the stopping edge. The lower end of the lower tubular bus-bar clip is provided with a universal joint structure for achieving the connection between the vertical tubular bus-bar and an adaption tubular bus-bar below the vertical tubular bus-bar. The structure is advantaged by that: the structure is convenient to install and is especially suitable for the assembly of the tubular bus-bar in a vertically hanging status and the corresponding valve hall.
