摘　　要：以现代输电系统中常见的气体绝缘全封闭组合开关为研究对象,利用ANSYS有限元分析软件对组合开关进行了建模和模态分析,并与振动台试验测得的自振频率进行了对比,验证了ANSYS建模的合理性。同时,对组合开关采用铅芯橡胶支座隔震前后的情况进行了非线性动力时程分析,分析结果表明:隔震后组合开关的自振周期明显延长,能够有效地避开地震的卓越周期,并且组合开关的峰值位移和最大绝对加速度较隔震前明显减小。证明组合开关采用铅芯橡胶支座进行隔震能够明显减小其地震响应,对研究高压电器设备的隔震技术具有一定的参考价值。In this paper, the gas insulated enclosed combination switch which is common used in modern transmission system is acted as the study object. Finite element analysis software ANSYS was used for modelling and analysis of the combination switch, and then the modal＇ s frequency was compared with that from shaking table test, which verify the rationality of the ANSYS modelling. At the same time, the nonlinear time history of the combination switch with and without lead plug rubber isolation bearing were conducted The simulation results show that： After isolation not only the natural period of vibration of the combination switch is prolonged to avoid predominant periods of earthquakes, but also the peak displacement and maximum absolute acceleration are obvious reduced. It means that the seismic response of the combination switch can be significantly reduced by use of the lead plug rubber bearing （LRB） isolation, the paper may give a reference to study of the high voltage electrical equipment isolation technology.
