AI Technical Summary

Technical Problem

The interphase spacing rods of existing transmission lines fail to effectively prevent the wire from dancing during long-term use, resulting in wire damage, affecting the safe operation of the transmission lines and increasing maintenance costs.

Method used

A device consisting of three six-splitting damping spacer rods is adopted, each of which is equipped with six wire chucks, and a hydraulic shock absorber, a damping ball and a viscous damper are provided between the two adjacent damping spacer rods to form a coordinated energy-consuming vibration-absorbing network.

Benefits of technology

The hydraulic shock absorber consumes the energy of the wire dancing, and the damping ball uses inertia to resist the overall dancing, and the viscous damper further enhances the energy consumption effect, significantly reduces the amplitude and period of the wire dancing, and improves the stability and safety of the transmission line.
