Therefore, the vibration of electric structures should be reduced, to protect the electric system. In this paper, ANSYS software is applied to establish a finite element model of GW7-252 isolation switch, the time history for the resonance amplitude wave is analyzed according to the specifications of the device. The dynamical response of the original structure is discussed. A finite element damping model of the device with the shock absorbers developed by China Electric Power Research Institute is built, the simulated results are compared with those of the original structure. When the peak acceleration is changed from 0.15g to 0.465g, a seismic efficiency is varied from 37% to 75%. As the peak acceleration increases, the shock absorbers go into the process of plasticity energy consumption. When the peak acceleration is 0.465g, the safety factor of the isolating switch supporting porcelain is 0.41, but it becomes 1.72 with the shock absorbers. The results show that the shock absorbers are effective to reduce the structure vibration in earthquake. The metal shock absorbers designed by the passive energy dissipation method are easy to make and convenient to install, with good results. They can be widely used in high voltage electric equipment., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null,

articleAbstract=电力系统中的高压电气设备在地震中很容易受到破坏，因此进行抗震减震分析非常必要。抗震分析中常采用数值模拟和振动台实验相结合的方法，但设备造价比较高，数值模拟则是一个廉价且易于控制的分析手段。本文运用ANSYS软件建立GW7-252隔离开关的有限元模型，根据规范对设备输入共振调幅波进行时程反应分析，讨论原结构在共振调幅波作用下的动力学反应，然后采用中国电力科学研究院研制的减震器建立结构的减震模型，输入共振调幅波后，将减震模型的时程反应结果与原结构进行比较，减震效果良好。,
