摘要

An analysis method introduced in a recent paper has been applied to four ACSR conductors. Calculations are carried out to further illustrate the method, showing the relationship between wind energy input to the conductor and energy loss from the conductor when it is vibrating at a constant loop velocity equal to 200 mm/s. The difference between the two energy curves defines an energy gap or shortfall that must be supplied by vibration dampers. This energy gap is seen to depend strongly on the conductor tension, the conductor diameter, and the conductor span length. An illustration is given showing how well a Stockbridge damper or an impact damper fills the energy gap. One additional illustration is given applying the same principles to a triple-conductor bundle and an impact type of damping spacer. Finally, field tests conducted earlier on the four sample conductors are compared with the calculated results.
