摘要:
以500 kV GIS罐式避雷器为原型,采用有限元软件ANSYS对其进行结构力学分析。包括结构静力分析,模态分析以及抗震性能研究。其中抗震性能研究包括避雷器直接固定于地面与搭配支架使用的情况。并以支架高度为变量,研究了在不同高度支架下避雷器的地震响应。发现该避雷器由于线度小,整体刚度大,基频高,对地震波响应不明显,并最终验证该500 kV GIS避雷器符合GB 50260—2013《电力设施抗震设计规范》规范规定的烈度9度抗震要求。
Abstract:
Based on 500 kV GIS tank arrester. The finite element software ANSYS is adopted to make structure mechanical analysis, including the static mechanical analysis, modal analysis, and seismic performance analysis. The seismic performance contains two cases; one is the arrester was clamped to earth, the other is the arrester clamped to the stand. In addition, we varied the height of the stand and analyzed the seismic response respectively. It is found that because of the small length and relatively strong rigidity of the arrester, it shows high 1st eigen-frequency so that it is insensitive to the seismic wave. Finally we verified that this arrester meet the seismic requirement of 9 degree intensity which is specified in GB50260—2013.
