| 摘 要： | 汶川地震震害调查表明，管母线连接电气设备在地震中破坏情况严重。为了研究此类设备的地震响应，建立了管母线连接电气设备耦联体系的有限元模型，采用时程分析法对模型进行了地震响应分析，比较单体设备和管母线连接设备的动力特性和地震响应，并且探讨了管母线不同设置方式对连接系统的影响。分析结果表明，管母线连接设备系统中，高频设备的位移响应较其独立设备时放大，低频设备的位移响应较其独立时减小；在耦联系统中，伸缩节与低频设备连接时耦联系统的动力响应小于伸缩节与高频设备连接时系统的动力响应。进行管母线连接的电气设备抗震设计时，应充分考虑电气设备的动力特性和伸缩节的设置方式。

| Abstract: | Substation equipment interconnected by rigid bus was badly damaged during the Wenchuan Earthquake.In order to study the seismic response features of this type of equipment,a FEM model was established for the coupling system of the substation equipment interconnected by rigid bus and a time-history analysis was conducted on the model's seismic response.The dynamic properties and seismic responses of the independent equipment and the equipment in the coupling system were compared,and the impact of different a... |
