摘要
针对地震中气体绝缘金属封闭输电线路(GIL)的潜在故障问题,基于海南昌江某项目220 kV GIL物理结构,建立了三相输电管道水平敷设下的3维有限元模型,并提出依据现行设计规范模拟GIL地震响应的分析方法。首先通过模态分析获得了GIL结构的振型特性,利用反应谱分析方法研究了不同地震反应谱激励下GIL地震响应的薄弱部位;然后对不同地震激励下GIL的抗震性能进行了具体评估,并进一步对GIL薄弱部位的地震响应规律进行分析总结。结果表明:建模所依据的220 kV GIL输电管道结构能够耐受6度的地震烈度,但对于7度及以上的地震烈度,其有损坏的可能;绝缘子和导体是GIL结构地震响应的薄弱部位;合理选取绝缘子和导体的机械参数能有效提高GIL的抗震能力。
To solve the potential failures of gas insulated transmission line(GIL) under earthquake, a three-dimension finite element model of the three-phase transmission pipeline was established based on a project of Hainan Changjiang 220 kV GIL, and a methodology to simulate GIL seismic response was also proposed based on the current design specifications. Firstly, we obtained the modal characteristics of a GIL using modal analysis, and assessed the seismic response of the GIL weak parts under different earthquake response spectra using the response spectrum analysis. Then, we evaluated the seismic performance of GIL under different earthquake responses, and also analyzed the response regularity of the GIL weak positions. It turns out that the model on the basis of 220 kV GIL transmission pipeline can tolerate the seismic intensity of 6 degree, however it will break down when the seismic intensity reaches 7 degree and above. And the insulators and conductors are the weak parts of GIL under seismic excitation, however, proper selection of the mechanical parameters of insulators and conductors can significantly improve the seismic capability of the GIL.
