Abstract

The invention discloses a split conductor anti-galloping device. The split conductor anti-galloping device comprises a support, and a lead wire clamp is uniformly arranged towards outside on the support. The split conductor anti-galloping device is characterized in that a circular cylinder is also arranged on the support; a spring and an additional weight ball are arranged in the circular cylinder; one end of the spring is connected with the additional weight ball, and the other end of the spring is connected with the circular cylinder; the lead wire clamp is rotatablely connected with the support through a rotating shaft; the circular cylinder is in closed connection with the support; and antifreeze solution is filled into the circular cylinder. In the split conductor anti-galloping device, the energy dissipation is performed by adopting a spring quality system so as to retard galloping, and after being iced, each sub-lead of a split conductor can be adjusted automatically by adopting the lead wire clamp which is arranged rotatablely, so that each sub-lead is iced uniformly so as to remove the galloping, and the energy dissipation effect is enhanced further by adopting the mutual effect of the antifreeze solution and the spring quality system; and therefore, compared with other anti-galloping devices, the split conductor anti-galloping device has the advantages of excellent effects of galloping prevention and galloping elimination.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a dance preventer for split wires. Background technique [0002] Split wire is a wire erection method adopted by high-voltage transmission lines to suppress corona discharge and reduce line reactance. That is, each phase conductor is composed of several sub-conductors with smaller diameters, and each sub-conductor is spaced at a certain distance and arranged in a symmetrical polygon. The number of split wires for high-voltage transmission lines is generally 2 to 4, and the number of split wires for UHV transmission lines can be up to 8. [0003] When the existing split conductors are erected, spacers need to be used to ensure a certain distance between each sub-conductor. However, even if spacer rods are used, the problem of conductor galloping needs to be considered when erecting split conductors. The conductor galloping refers to the fact that the conductors of ove...
