在地震作用下，电容器成套装置容易受到破坏。对某种型号35 kV电容器成套装置的抗震性能进行鉴定分析，并对GB 50260—1996《电力设施抗震设计规范》和IEEE Std 693—2005标准推荐的抗震验算方法进行比较分析。应用通用有限元程序ANSYS建立此电容器结构体系的有限元模型，进行了地震作用下的动力反应分析。分别输入正弦共振调幅五波、Elcentro波、Landers波和人工波的动力时程分析结构的响应。通过增加2个绝缘支柱瓷瓶，此电容器成套装置满足抗震性能的要求。电容器的抗震性能高于IEEE Std 693—2005定义的中等抗震水平，略低于高等抗震水平。

Capacitor installations are vulnerable during earthquake. The seismic behavior of 35 kV capacitor installation was studied, as well as the comparison between two methods proposed by the ‘Code for Design of Seismic of Electrical Installations’ and the ‘IEEE Std 693—2005’ for seismic design. The 35 kV capacitor installation was modeled and its seismic response was analyzed using the finite element software ANSYS. The dynamic characteristics was investigated by inputting different waves respectively, such as five amplitude modulation resonance sine waves, Elcentro earthquake wave, Landers earthquake wave and artificial earthquake wave. The result shows that the capacitor installation can meet require of seismic behavior through adding two porcelain bushings, which is higher than the middle seismic level and lower than the high seismic level defined in the ‘IEEE Std 693—2005’.
