A wire dance prevention device

Abstract

The invention relates to a conductor anti-galloping device, which comprises a damping anti-galloping assembly, a flow-disturbing anti-galloping assembly and a fixing assembly, and is characterized inthat the damping anti-galloping assembly and the flow-disturbing anti-galloping assembly are arranged inside the fixing assembly, the left end of the damping anti-galloping assembly is fixedly connected with the left end of the fixing assembly, the right end of the damping anti-galloping assembly is fixedly connected with the right end of the fixing assembly, both the left end and the right end ofthe fixing assembly are fixedly connected with a conductor, and the flow-disturbing anti-galloping assembly is wound on the wire. The damping anti-galloping assembly can automatically compress and stretch according to the galloping of the conductor, the elastic force of a rubber spring can enable the split conductor to be restored to the original position so as to realize the automatic restoration of the split conductor of a transmission line; and the flow-disturbing anti-galloping assembly can generate a flow-disturbing effect on the flow field and change the flow field characteristics around the conductor, and can also avoid resonance between a flow-disturbing line and the conductor, thereby reducing the galloping probability of the transmission line, and improving the safety and reliability of the line. The conductor anti-galloping device has the advantages of reasonable structure, convenient installation, excellent performance, safety, reliability and low cost.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, and is an anti-dance device applied to split conductors of overhead power transmission lines. Background technique [0002] As an important facility for the transmission, regulation and distribution of electric energy in the power system, transmission lines are becoming more and more complicated with the increase of power transmission distance and capacity, which will inevitably make the safe and stable operation of transmission lines more critical. The safe and reliable operation of the power grid is closely related to the transmission line. [0003] Galloping of overhead transmission lines seriously threatens the safe operation of transmission systems. EHV transmission wire galloping is a self-excited vibration with low frequency (about 0.1Hz to 3 Hz) and large amplitude (about 5 times to 300 times the diameter of the transmission line), which forms one or more half waves in t...

Problems solved by technology

However, since the turbulent wire is wound on the fixed column, it does not directly produce a turbulent effect on each wire; the damping device is set in a relatively narrow frame, and the damping effect of the wind damping sheet is very small, preventing The dance effect is not good, which directly affects the safety of the transmission line
