Questions about the vibration damper
Thread Content
May I ask everyone, what is the principle behind a double-loop damping vibration suppressor as an electrical device? Thank you!
Circular single-conductor busbars generate Karman vortex streets in gentle winds; therefore, measures to eliminate wind-induced vibrations must also be considered in the design. The measures taken to eliminate this issue generally include the following methods: (1) Installing powered dual-ring damping vibration suppressors ； (2) Install damping wires inside the pipe ； (3) Change the support method. The tubular busbar must also appropriately extend the end-span busbar, while eliminating end effects by adding shielding rings or spheres at the ends. The above information was found on the Internet, and it can be seen from this that this double-ring damping vibration suppressor is not actually a purely electrical device; it is mainly a mechanical measure taken to prevent vibrations in circular tube busbars!
