摘要

穿墙套管作为一种水平安装的双侧长悬臂特高压直流设备

其抗震性能非常重要。为减小穿墙套管在地震下的响应

为穿墙套管设置了由摩擦型阻尼器构成的减震装置

并对带有减震装置的真型穿墙套管进行了地震模拟振动台试验。通过白噪声扫频试验获得了穿墙套管的动力特性

通过输入设备场地人工波

获得套管关键位置的地震响应。结果表明:在目标峰值下

带有减震装置的穿墙套管最大位移响应为123.91mm

其中由于连接板的摆动造成的刚体位移达到最大位移峰值的1/6;穿墙套管根部最大应力满足抗震要求。试验研究表明带有该减震装置的穿墙套管满足抗震要求

验证了该减震装置的可行性。

Abstract

UHV（ultra-high voltage） DC（direct current） wall bushing is a kind of horizontally installed cantilever equipment which makes it vulnerable during earthquake motions. In order to reduce its seismic responses

a damping device consisting of friction dampers was installed

and the shaking table test on the wall bushing with the damping device was carried out. The dynamic characteristics were acquired by white noise excitation. The seismic responses of the key position in the wall bushing were obtained under artificial input ground motion. The results reveal that the maximum displacement of wall bushing with the damping device is 123.91 mm

among which the displacement caused by the rocking effects of installation plate is up to 1/6. The safety factor of maximum stress at the bottom cross section of the wall bushing can satisfy the seismic requirements. The results indicate that the wall bushing with the damping device meets the seismic requirements

verifying the feasibility of this damping device.
