S7-200/10 变型变压器抗震分析

SEISMIC RESPONSE ANALYSIS FOR S7-200/10 POWER TRANSFORMER STRUCTURE

本文采用有限元法分析了电力变压器结构的抗震特性，并考虑了其中液体对变压器结构动力特性的影响。文中提供了一种可供变压器结构抗震分析的方法，并以Ｓ７－２００／１０型变压器为例进行了理论计算和原型实验。结果表明：本文提供的分析方法是可靠的，可以满足变压器行业抗震设计分析的需要。

The seismic responses of main structure of power transformer are analysed with FEM and the analytical results in consideration of liquid effects are presented.As and 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 of earthquake resistance of transformet.
