Seismic behavior of electric switch

Funding entity ABB Power Technology


The project aims to study the seismic behavior of the structure of an electric switch of 72.5 kw. The device is basically constituted by a base steel structure and the switching elements: ceramic insulating materials and other metallic materials. The actions on the structure take into account the simultaneous existence of acceleration fields not only in a horizontal direction but also in a vertical one. The definition of the response spectrum of accelerations, as well as the comparison of tensions criteria, have been carried out according to Chilean codes. A finite element model has been developed with the most important dynamic characteristics of the structure and a modal spectrum analysis is used to calculate the structure response.
