This paper describes the seismic test and numerical stress analysis of a 170 kV Gas-insulated switchgear (GIS) to see the structural and operational safety. Both the seismic test and numerical FEA (finite element analysis) are performed according to the procedure of Korean and International (IEC-62271) seismic standards. The GIS is mounted on the shaking table for a seismic test at KIMM (Korea Institute of Machinery and Material) to see the stress level and safety under earthquake loading conditions. The FEA analysis is performed to compare with the seismic test. Both the natural frequency (NF) and stress results from the numerical computation and seismic test are close and show adequate electrical and structural safety margin.

170 kV GIS（气体绝缘开关设备）的抗震安全评估，通过大振动台的抗震试验和韩国和 IEC 抗震标准的有限元分析

本文介绍了 170 kV 气体绝缘开关设备 (GIS) 的地震试验和数值应力分析，以了解其结构和操作安全性。地震试验和数值 FEA（有限元分析）均按照韩国和国际 (IEC-62271) 地震标准的程序进行。GIS 安装在振动台上，用于在 KIMM（韩国机械和材料研究所）进行地震试验，以查看地震载荷条件下的应力水平和安全性。进行 FEA 分析以与地震试验进行比较。数值计算和地震试验的固有频率 (NF) 和应力结果都很接近，并显示出足够的电气和结构安全裕度。
