摘　　要：作为生命线工程的重要组成部分,变电站若在地震中遭到损坏,将带来难以估量的直接和间接损失。较之常规电压等级设备,特高压电气设备结构高、质量大,地震易损性更高,其一旦在地震中损坏,将造成更严重的损失。为充分考核特高压主变压器套管抗震能力,本研究针对5支国内特高压工程常规主变压器套管进行地震模拟振动台试验研究,采用输入白噪声随机波和人工拟合时程波的方式分别研究各套管动力特性及抗震性能。试验结果表明,特高压主变压器套管根部应力基本满足设计基本地震加速度0.3 g的抗震考核。安装法兰及构件连接位置是套管地震易损性较高的部位,需在设计中加以强化。As an important part of lifeline engineering,it will bring incalculable economic losses if the substation was destroyed in the earthquake.Compared with conventional voltage electrical equipment,the ultra-high voltage(UHV)electrical equipment get high and heavy structure,which make it get higher seismic vulnerability.In order to study the seismic behavior of UHV main transformer bushing used in UHV Substation,5 prototype bushings were tested by seismic simulation shaking table.The dynamic characteristics of the specimen were obtained by input of white noise random wave,and the acceleration,strain and displacement response of the key parts was obtained by the input of standard time history wave.Test results show that in the standard time history wave input of 0.3 g design basic acceleration of ground motion,the strength of the bushing meets the requirements of seismic design;the mounting flange and connected component are get high seismic vulnerability which needed to be strengthen in design stage.
