GALLOPING BEHAVIORS OF SECTOR-SHAPE ICED EIGHT BUNDLE CONDUCTORS1)

  • The sector-shape iced eight UHV (ultra-high voltage) bundled conductors are in a condition more similar to the heavy ice conditions than that of the crescent-shape ice. Test models of sector-shape cross section iced eight bundled conductors are prepared. The aerodynamic coefficients of the sector-shape iced conductor models varying with the wind attack angle are obtained by the wind tunnel test. Based on the wind tunnel test results of sector-shaped iced eight bundle conductors, the numerical methods are used to study the effects of critical parameters on the galloping of eight sector-shaped iced conductors. The effects of the wind velocity, the span length and the initial wind attack angle on the galloping of sector-shaped iced eight bundled iced conductors are investigated. The result shows that the sector-shaped iced eight conductors can reflect the galloping characteristics of eight bundle conductors under heavy ice conditions.
