In an electrical substation or converter station, suspension equipment is connected to an adjacent post insulator by a rigid busbar or flexible conductors if the horizontal displacement is significant. In order to investigate the coupling effect between suspension and post equipment connected by a rigid busbar, a scaled‐down model based on a multilayer suspended thyristor valve and an adjacent post insulator was tested. Additionally, an analytical model, which took into account the out‐of‐plane and torsional motion, was established. The test results showed that the damping of the suspended valve approximated to stiffness‐proportional damping. The rigid busbar significantly reduced the seismic responses of both the valve and the post insulator by changing the vibration modes and increasing the damping ratio. Based on the analytical model, the rigid busbar connection is recommended for stiff insulators with a low fundamental frequency. A hard soil site, chain connection, low damping ratio, and an appropriate layout all contribute to the advantages of a rigid busbar. A telescopic busbar using additional rotational and axial damping also can improve the system's seismic performance. Rather than automatically installing flexible conductors, it is recommended that equipment parameters be used to determine an appropriate connection type between suspension equipment and an adjacent post insulator.

多层悬挂设备和相邻具有弹性-粘性连接的支柱绝缘子的动力特性

在变电站或变电站中，如果水平位移很大，则悬架设备通过刚性母线或柔性导体连接到相邻的支柱绝缘子上。为了研究悬架与通过刚性母线连接的立柱设备之间的耦合效应，测试了基于多层悬挂晶闸管阀和相邻立柱绝缘子的按比例缩小模型。另外，建立了一个分析模型，该模型考虑了平面外和扭转运动。测试结果表明，悬架阀的阻尼近似于刚度-比例阻尼。刚性母线通过改变振动模式和增加阻尼比，大大降低了阀门和绝缘子的地震响应。根据分析模型，对于具有低基频的刚性绝缘体，建议使用刚性母线连接。坚硬的土壤，链条连接，低阻尼比和适当的布局都有助于刚性母线的优势。使用附加的旋转和轴向阻尼的伸缩母线也可以提高系统的抗震性能。建议您使用设备参数来确定悬挂设备和相邻的支柱绝缘子之间的适当连接类型，而不是自动安装柔性导体。使用附加的旋转和轴向阻尼的伸缩母线也可以提高系统的抗震性能。建议不要使用设备参数来自动确定挠性导体，而是要使用设备参数来确定悬挂设备与相邻支柱绝缘子之间的合适连接类型。使用附加的旋转和轴向阻尼的伸缩母线也可以提高系统的抗震性能。建议不要使用设备参数来自动确定挠性导体，而是要使用设备参数来确定悬挂设备与相邻支柱绝缘子之间的合适连接类型。
