【摘要】 为1 000kV氧化锌避雷器的底部设计了铅芯橡胶支座隔震装置。利用ANSYS有限元软件建立避雷器模型,计算了安装隔震装置前后,在风荷载、接线端子板荷载和水平地震作用下避雷器的内力与位移。安装隔震装置后,避雷器在地震作用下的内力与相对位移有大的降低,整个结构在各种荷载组合下均具备足够的安全储备。更多还原

【Abstract】 An isolatim system is designed for mitigating earthquake-induced disasters of 1000kV metal oxide arresters,which consists of several lead-rubber base isolators.The finite element models of an arrester,are established with the general finite element analysis software ANSYS,one model is with isolation,but another is without.The internal forces and displacements of the two models are calculated under wind loading,junction board loading and horizontal seismic loading respeclively.In comparison with the model with out isolation,the seismic responses of the model with isolation are reduced distinctly due to the effects of the isolation.The whole structure of the arrester with isolation is enough safe.更多还原
