The Relation between Structural Stress and Cladding Ice Thickness of Transmission Tower on the Condition of Vibrate

Abstract:

Transmission tower security is the first requirement of intelligent power grid and exploring transmission tower line failure mechanism is a technical difficulty under the condition of cladding ice. The wind vibration model and relation between internal force distribution and cladding ice thickness of transmission tower system are researched in this paper.Numerical simulation results show that ice cover thickness increases with insulator string tension distribution changes, and nonlinear characteristics of cladding ice thickness and the distribution of stress transmission tower significantly increasing changes.The numerical results provides certain theoretical foundation for recognizing the failure mechanism of cladding ice transmission tower under complex load condition.
