Abstract

The invention relates to a tubular bus suspension device, which comprises a three-point suspension fitting, a jumper wire clamp and an insulator string, wherein the upper end of the insulator string is connected with a framework cross beam hanging point, the lower end of the insulator string is connected with a hanging point in a main suspension structure of the three-point suspension fitting, andthe tubular bus is fastened through a tower type hanging point fitting; a bilateral auxiliary inhaul cable suspension structure of the three-point suspension fitting extends to the two sides of the main suspension structure in the direction parallel to the tubular bus, the tubular bus is fastened by tensioning hanging points, and the length of the bilateral auxiliary inhaul cable suspension structure can be adjusted by extension pull rods; the adjacent spacing tubular buses are connected through the jumper wire clamp, and wire counterweights are added inside the two sides of each jumper wireclamp. The three-point suspension fitting is arranged, and the length of bilateral auxiliary inhaul cable suspension structure of the three-point suspension fitting is adjusted according to needs, sothat the suspension distance between the midspan tubular bus and the adjacent spacing tubular bus is shortened. The problem of overlarge flexibility of the midspan tubular bus in the interval and theproblem of overlarge flexibility of the tubular bus between the adjacent interval suspension points are solved.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission and transformation, and relates to a tubular busbar suspension device. Background technique [0002] Tubular busbar has been used as a standard busbar form of substation power distribution equipment. For large-span suspended tubular busbars, the large deflection will bring the following problems: (1) If a vertical telescopic isolating switch is used on the side of the busbar, the offset of the static contact of the isolating switch will be too large, and the isolating switch cannot be opened normally. combine. (2) The bending of the suspended tubular busbar is too obvious, which affects the appearance. (3) The suspended tubular busbar affects the live distance verification of the electrical equipment below it. The control of the deflection of the large-span suspended tubular busbar is mostly done by adding frames to shorten the suspension distance of the tubular busbar, whic...
