摘要: 依托±800 kV布拖换流站一期工程，对直流场电气设备耦联回路进行有限元抗震分析。采用振型分解反应谱法和时程分析法对支柱绝缘子回路和直流滤波器回路进行抗震分析，研究了设备在地震作用下的应力和位移，为电气金具设计提供数据支撑。Abstract: Seismic study was conducted on coupling circuit of electrical equipment in the direct-current field, based on ±800 kV Butuo converter station. The spectrum method and the time history analysis were adopted in the seismic study, in which the stress and displacement were studied, providing data support for electrical fitting design.
