Abstract
The high-voltage disconnector is a large structure which contains two poles. The structure is 6 meters height and is used to connect and disconnect the high voltage electrical circuit in order to assure the power connections between cities or remote locations. The purpose of the study is to simulate the effects of earthquakes on the circuit breaker structure using FEM. The damage of a high-voltage disconnector determined by earthquake has determinant implications in breaking the power supply for large territorial areas. So, the design of the high-voltage disconnector structure must include the simulations of the earthquakes, made by experiments and by Finite Elements Methods programs. The paper present a Finite Element model of the high-voltage disconnector made using ANSYS program and the modal analysis of the model. The modal analysis is the first step in earthquake F.E.M. simulation. The results presented are the first 10 natural frequencies and the corresponding vibration modes. The FEM model can be used in earthquake simulation by FEM.
