特高压GIL现场交接验收与机械缺陷检测平台的设计与实现

Gaoya dianqi
为了探索适合特高压GIL设备的现场交接验收及机械缺陷检测方法，文中对传统GIL设备交接验收时的交流耐压试验、投运前绝缘性能考核试验及局部放电试验进行了改进，采用与振动检测法相结合的方式。在此基础上研制了GIL综合试验与机械缺陷检测分析平台，并融合了出厂试验数据、历史运行数据、常规检测数据及改进后的交接试验数据进行多源多参量分析。解决了传统方法无法判别GIL设备微小机械缺陷的问题，使运维人员能够更加全面的掌握GIL设备的状态。现场应用实例表明，该平台能切实提升特高压GIL设备的现场交接验收效率及规范性 ...

多点输入下550 kV气体绝缘金属封闭输电线路（GIL）抗震性能研究

Gaoya dianqi
为研究气体绝缘金属封闭输电线路（GIL）地震响应规律，对某550 kV GIL管道单元进行了地震模拟振动台试验及有限元分析，并基于试验验证的GIL管道单元模型建立了全站域下的部分GIL有限元模型，研究其在多点输入下的抗震性能。研究结果表明：试验及有限元分析下三支柱绝缘子的安全系数均最小，为GIL的薄弱部位；GIL管道单元有限元分析结果与振动台试验结果吻合较好，模态分析、加速度响应峰值、Von-Mise应力的最大误差分别为8.5%、8%、12%，表明建立的有限元模型及参数设置较为合理 ...
