The Analysis for Seismic safety evaluation of Gas Insulated Switchgear(GIS):The Seismic Analysis of Smart 245kV GIS

摘要

Recently, the important of the seismic safety evaluation of a large-scaled electric equipment is increasing. In order to evaluate the seismic safety, the seismic analysis of the large devices such as GIS(Gas Insulated Switchgear) or equipment for electric power substations or nuclear power plant has been conducted. Because the seismic qualification by experiment need too large shaking table facilities and very expensive, the computer simulations would be preferred rather than measurements. However, for the precise simulation, many parameters such as effective mass, mode, RRS(Required Response Spectrum) should be considered properly. In this paper, the seismic analysis of the GIS producted by LSIS had used the finite element method and analyzed using ANSYS Workbench. The results can provide a reference for the seismic reliability analysis of the high-voltage switchgear equipments.
