Research on the Dynamic Response of EHV Transmission Tower under Ruptured Icing Conduction

Taking a typical 500 kV transmission tower-line system as an model,using nonlinear finite element software ANSYS / LS-DYNA,without considering the collision impact between the wire and the ground,simulates two breakage conductions of breaking four sub-conductors at the same time and breaking sequentially under the uneven icing conduction,the dynamic effect of the conductor breakage impact load on the transmission tower is analyzed. The dynamic effects of stress and displacement of the tower head is obvious.
