摘要
采用有限元法分析了电力变压器本体结构的自振特性,并给出了考虑其中液体影响的变压器结构抗震的分析方法。以S7—200/10型变压器为实例,进行了理论计算和原型实验,结果表明,本文的分析方法是可靠的,可以用于变压器抗震设计分析。
The natural vibration characteristics of main structure of power transformer are analysed with FEM and the analytical method for earthquake resistance of transformer structure with consideration of liquid effects is presented. As an example theoretical calculation and prototype experiment for S7-200/10 type transformer are carried out. Results show that the proposed method is reliable and it can be used for analysis and design for earthquake resistance of transformer.
