【摘要】：电抗器是重要的变电站设备,在地震中会遭受各种形式的破坏,其中瓷质套管的损坏尤为常见。该文通过特高压电抗器-瓷质套管体系缩比模型振动台试验,研究了其在不同地震波输入时套管的地震响应,分别得到了不同工况下套管的加速度响应、位移响应和应变响应,分析了套管加速度峰值放大系数、位移峰值和应变峰值,评价了其抗震性能。建立了与试验相一致的数值仿真分析模型,通过频率、套管根部应力和套管顶端相对位移的比较,验证了数值分析模型的有效性,同时分析了特高压原型电抗器的抗震性能。之后对特高压电抗器-套管体系本体地震动力放大作用展开研究,提出以应力峰值为参量的本体对套管地震动力放大作用的放大系数计算方法。
[Abstract]:The reactor is an important equipment in substation, the earthquake will suffer from various forms of damage, the damage of porcelain casing is particularly common. Through the UHV reactor - porcelain casing shrinkage test system than shaking table model, were studied in the different earthquake input casing earthquake response are obtained. The acceleration response of casing under different conditions, the displacement response and strain response analysis of casing peak acceleration amplification coefficient, displacement and strain peak, the seismic performance evaluation was established. The numerical simulation is consistent with experimental analysis model by frequency, casing root stress and relative displacement of the top of the sleeve, to verify the validity of the numerical analysis model at the same time, analysis of the seismic performance of the UHV prototype reactor. After the UHV reactor casing body system of seismic amplification research, put forward to The calculation method of the amplification factor of the seismic dynamic magnification of the casing by the bulk of the stress peak is the parameter.
