【摘要】 建立了某型户内72.5 kV气体绝缘开关设备(gas insulated switchgear,GIS)的有限元模型,并根据GB/T 13540—2009采用响应频谱法对其进行了抗地震分析,给出了正常运行工况和地震载荷组合工况下的计算结果。结果表明:该电气设备满足烈度为9度的抗震性能要求,文中所确定的分析方法和步骤也适用于其他类型的高压设备的抗震分析。更多还原

【Abstract】 A finite element model of some type of 72.5 kV gas insulated switchgear is built,and anti-seismic analysis for the model is conducted with the response spectrum method according to the national standard GB/T 13540—2009.Calculation results for the case of normal load and the case with both normal and earthquake loads show that this gas insulated switchgear meets the anti-seismic performance requirement for level 9 of earthquake intensity.The proposed analysis method and procedure can also be applied to anti-seismic performance of other high-voltage equipments.更多还原
