摘要
对湖南500 kV复沙Ⅰ线倒塔段应用大型通用有限元程序AN SYS建立单元模型,计算出铁塔随导线覆冰厚度变化的极限承载力,分析了该事故段铁塔倒塌的原因。根据计算结果,对铁塔的2种局部加强方案进行核算,并提出改造建议。
The tower falling down in Hunan 500kV Fusha line Ⅰ is modeled by large universal finite element software ANSYS, the ultimate loadcarrylng capacity of tower is calculated as the variation of the thickness of line ice accretion, and the cause of the tower falling down is analyzed. According to calculation result, two partial strengthen projects are calculated and checked, and countermeasures are suggested,
