Abstract:
In this paper are considered the aerodynamical instability conditions of over-head lines bundle conductors (the Lyapunov's nstability of equilibrium states of conductor subjected to wind) By means of the additivity hypothesis are introduced the aerodynamical characterizations of bundle conductor: drag and lift coefficients, the aerodynamic quality and the stability reserve. The wind tunnel experiments, which were executer in CAHI, confirm the adequacy of instability conditions and additivity hypothesis. We give a method of the stability estimation for any bundle conductors configurations, consider phases bundled on 3 , 4 , 5 , 6 conductors, which are used in Russian energetic building. Are given the aaerodynamical stability estimations and choice recommendations for installation states for each of configurations.
