Experiment Study on Dynamic Effects of Ice Shedding on Overhead Transmission Line

Abstract:

The vibration caused by ice shedding from overhead transmission line will lead to a great damage to transmission line in ice disaster areas, so it is of great significance for line design to research the vibration characters caused by ice shedding. In order to research the characters of tensile force in ice shedding conductor, the ice shedding phenomenon is simulated in laboratory by a single conductor between isolated span. The result shows that: the ice-shedding response amplitude will increase as the increase of ice thickness, the decrease of the sag-span ratio or the increase the shedding ice quantity; the max dynamic tension caused by part of ice shedding from conductor may larger than the whole ice-shedding.
