Embodiment 2

[0014] Embodiment 2 of the pipe busbar suspension fittings of the present invention: as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the adjustable connecting frame is composed of a fixed connecting plate 11 and a second adjusting bolt 12 vertically mounted on the fixed connecting plate 11, and the fixed connecting plate 11 A third hinged plate hinged with the suspender is vertically fixed on the upper surface of the upper plate. The pipe busbar clamp is hinged at the lower end of the second adjusting bolt. Depending on the adjustment function of the second adjusting bolt 12, the pipe busbar clamp can be directly adjusted. In order to meet the needs of the pipe busbar clamps to clamp pipe busbars of different heights, at the same time, any angle between the hinge axis of the pipe busbar clamp and the hinge axis of the adjustable connecting frame can be adjusted by the rotation of the second adjusting bolt 12.

Abstract

The invention discloses a tube busbar suspension fitting for a converter station valve hall. The tube busbar suspension fitting comprises an anti-corona ball and a hanging rack which is fixedly arranged on the inner sphere of the anti-corona ball and which is used for suspending a tube busbar. The hanging rack comprises a hanging rod which penetrates the top of the anti-corona ball and which is used for connecting to insulator strings on the top of the valve hall. An adjustable connecting rack with longitudinally adjustable length is hinged to the lower end portion of the hanging rod, and supporting claws distributed along circumstance of the anti-corona ball evenly are connected between the adjustable connecting rack and the anti-corona ball. A tube busbar clamp for matching with the tube busbar in a hoop manner is hinged to the bottom of the adjustable connecting rack. A single tube busbar is clamped through the tube busbar clamp to realize suspension of the single tube busbar in the valve hall, the need of suspending the single tube busbar can be met, and the tube busbar suspension fitting has the advantages of convenience and rapidness in mounting; furthermore, the length of the adjustable connecting rack can be adjusted longitudinally, accordingly the length of the tube busbar clamp in the valve hall can be adjusted directly, and the need of clamping tube busbars of different lengths through the tube busbar clamp can be met.

Description

technical field [0001] The invention relates to a pipe bus suspension fitting for a valve hall of a converter station. Background technique [0002] The valve hall of the converter station of the UHV DC transmission system is a closed space, in which there are converter valves, transformer bushings, wall bushings and other equipment. Different equipment needs to be connected by pipe bus to form a transmission circuit. To realize the conversion of AC and DC, since the influence of earthquake, thermal expansion and contraction of materials, electromotive force, corona, etc. Various working conditions. [0003] For example, the Chinese patent CN202268664U discloses a 250-tube busbar spanning suspension fitting for a 400kv converter station. The fitting is mainly composed of an anti-halo ball, a hanger and a positioning support structure. The left and right sides respectively have pipe busbar perforations for the pipe busbars to pass through horizontally, so that one end of th...
