特高压换流站气体绝缘金属封闭输电线路（GIL）抗震性能提升方法研究

Gaoya dianqi
随着气体绝缘金属封闭输电线路（GIL）在特高压换流电站中的广泛应用，地震对其结构安全的影响备受关注。文中基于精细化有限元模型，分析了GIL在地震作用下的响应特征，并针对抗震薄弱点提出了针对性的性能提升方法。研究表明，GIL的主要薄弱点位于竖向转角处，存在外壳强度破坏和内部导体接头拔出破坏两种模式。此外，支架的动力放大效应显著，加速度放大系数通常超过2.0，但支架的动力放大作用并非唯一决定GIL抗震性能的因素。通过提高支架的基频和固定支架与外壳的连接方式，能够有效降低内部导体的相对位移峰值和外壳的应力峰值，

金属消能器-屈曲约束支撑复合减震构件抗震性能研究

Jianzhu Gangjiegou Jinzhan
为提高屈曲约束支撑（buckling-restrained brace，BRB）在小变形阶段的消能性能，将金属消能器与国产Q355钢芯材的BRB并联，构成新型多级屈服复合减震（简称SD-BRB）构件。在试件小变形阶段，金属消能器率先屈服消能；当试件变形增大时，BRB进入屈服阶段，从而实现两阶段屈服设计目标。文中设计了2根试件，用以通过试验对比复合减震构件与常规BRB构件的抗震性能。试验结果表明：与国产Q355钢为芯材的BRB并联的构件其抗震性能满足建筑抗震设计规范的要求。相比传统BRB ...
