摘　　要：为研究550 kV油纸电容式套管的抗震性能,文中首先利用静力分析及反应谱分析对其进行了抗震强度计算;其次对550 kV油纸电容式套管进行了振动台试验,测试其地震响应。最后将抗震计算的结果与振动台试验的数据相结合,对套管的抗震性能进行评估,验证了套管抗震计算的有效性。结果表明,该套管可以满足0.3 g加速度的抗震要求,具有足够的安全裕度。文中同时分析了该套管在更高抗震烈度区域的适用性,讨论了通过增加瓷件厚度提高套管抗震性能的方法。In order to study the seismic performance of 550 kV oil⁃impregnated capacitive,static analysis and re⁃sponse spectrum analysis were used to calculate the seismic strength.Secondly,shaking⁃table test was carried out to test the dynamic response of the bushing.Finally,results of numerical simulation and the shaking table test data were combined to evaluate the seismic performance of the bushing.The effectiveness of the seismic calculation was also verified.Results showed that the bushing could meet the seismic requirements and had enough safety margin.The applicability of the bushing in the area with higher seismic level was analyzed.The method of increasing the thickness of the porcelain to improve the seismic performance of the bushing was also discussed in this paper.
