摘要
轨道交通供电系统在山地尤其高海拔地区建设条件相对恶劣,对供电系统设备的抗震性能的要求也不断提升。以XGN-40.5 kV气体绝缘金属封闭开关设备(GIS)为研究对象,采用有限元分析软件,建立三维有限元计算模型,在自重载荷条件下对其进行静力分析、模态分析和地震作用下的反应谱分析。计算结果表明:该GIS开关设备具有较好的抗震性能,在0.5g地震激励下的抗震性能满足规范要求。
The construction condition of rail transit power supply system is relatively bad in mountainous area,especially in high altitude area,and the requirement of seismic performance of power supply system equipment is also increasing.Taking XGN-40.5 kV gas-insulated switchgear(GIS)switchgear as the research object,using finite element analysis software,establishing the three-dimensional finite element calculation model,and the static analysis,modal analysis and response spectrum analysis under self-weight load are carried out.The calculation results show that the GIS switchgear has good seismic performance,and the seismic performance under 0.5g seismic excitation meets the requirements of the specification.
