The invention discloses a tubular busbar fitting for a valve hall of a converter station, relates to the technical field of fittings, and aims to solve the problem that the existing tubular busbar fittings could damage devices or be disconnected from the devices due to large stress under earthquake conditions and as a result, the valve hall devices lose basic electrical performance. The tubular busbar fitting for the valve hall of the converter station includes two first tubular busbars. The two first tubular busbars are used for one-to-one corresponding connection with two devices at one endand are connected integrally at the other end through a connection unit. The connection unit has a conductive structure. One end, adjacent to the connection unit, of each of the two first tubular busbars is connected with the conductive structure by a wire. The connection unit is provided with a voltage-sharing member for a uniform electric field. The connection unit may be deformed to allow the two first tubular busbars to move in a horizontal direction such that the distance between the ends, for connection with the devices, of the two first tubular busbars changes. The tubular busbar fitting for the valve hall of the converter station in the invention is used for realizing electrical connection, mechanical support and voltage-sharing shielding between the two devices in the valve hall of the converter station.
