Abstract

Aiming at that the wind tunnel tests on aerodynamic characteristics of iced conductors were not systematic enough, the wind tunnel test for different icing types was conducted to study the aerodynamic characteristics of iced conductors more systematically. It can accounts for the characteristics of structure and wind field. The aerodynamic characteristics of different icing types such as crescent, fan and corona shapes with different icing thickness were obtained, and the effect of mean wind speed, turbulence and two-dimensional flow on aerodynamic characteristics were also investigated. It is concluded that the icing shapes have much effect on aerodynamic characteristics. The aerodynamic characteristics of rigid segment model with crescent-shaped are regular, while these of corona-shaped and fan-shaped have more peaks and troughs. In addition, the aerodynamic instability of iced conductors is more pronounced in turbulence. Furthermore, the wind speed has significant effects on drag coefficient, but the effects on lift coefficient is little.
