Abstract
The dynamics force of iced-conductor is the driving force of conductor galloping; its variation is depended on the aerodynamic character of iced conductor. The aerodynamic character of iced conductor is the key factor of galloping of iced-conductor, but the result of theoretically analysis and numerical simulation has the certain limited, and it isn’t suited for the requirement of transmission line anti-galloping project. In the paper, basing on the development, research status and the theoretically analysis of iced-conductor aerodynamic character, the simulation tests in wind tunnel of typed iced conductor is stetted up and put into practice for typical shapes, namely, crescent-shaped and D-shaped, under different wind speeds and with different ice thicknesses, and the systemic study is carried into execution. The result of research indicated that the experimental result can not only provide the original date for the galloping analysis, but also validate the affectivity of numerical simulation, support the research of mechanism and control of galloping.
