| 摘 要： | 为研究铅金属减震器对特高压互连电气设备的减震效果,进行由硬管母线连接的特高压避雷器设备和电容式电压互感器设备组成的互连耦合体系的地震模拟振动台试验。通过白噪声扫频、抗震及减震试验,测定互连耦合体系抗震结构及减震结构的自振频率以及关键部位的应变、加速度响应。试验结果表明:抗震结构中避雷器设备的最大应变响应大于互感器设备,互连耦合体系中的避雷器设备属于易损设备;安装减震器后互连设备频率降低幅度较小,减震器基本不会影响电气设备的正常运行;安装减震器后互连耦合体系中的避雷器设备和互感器设备在较大峰值加速度地震波作用下,设备顶端加速度响应和最大应变响应均有较大幅度的降低,避雷器设备和互感器设备的最大应变响应的减震效率分别为75%和50%,减震效果显著,减震器的应用大幅提升了互连耦合体系的抗震能力。

| Abstract: | To investigate the damping effect of a lead damper on ultrahigh voltage (UHV) interconnected electrical equipment, we carried out a shaking table test on an interconnected coupling system comprising a UHV arrester and a capacitor voltage transformer. The equipment frequency and the strain and acceleration of some key components were measured using white noise sweep, seismic test, and damping test. The test results show that the maximum strain response of the arrester is larger than that of the transformer. The arrester of the interconnected coupling system is a vulnerable device. With dampers added, the frequency of the interconnected equipment slightly decreases; thus, the dampers cannot affect the normal operation of the electrical equipment. The top acceleration response and maximum strain response for the arrester and transformer device of the coupling system after adding dampers are greatly reduced under the action of seismic waves with large peak acceleration. The damping efficiencies of the maximum strain response for the arrester and transformer are 75% and 50%, respectively, and the damping effect is significant. The application of dampers greatly enhances the seismic capacity of the interconnected coupling system. |
