摘要
以某公司某型号变压器为例,通过理论计算和有限元大变形仿真分析,以变压器油箱箱体法兰为研究对象,对该变压器油箱吊装过程中的变形进行分析。经分析可知,增大下法兰厚度并合理地对螺栓重新排布,可以增强变压器油箱箱体法兰抵抗变形的能力,从而减小法兰间缝隙并减小法兰表面波纹状变形量。这一结论能为变压器油箱箱体设计提供理论参考。
In this paper,a certain type of transformer as an example,through theoretical calculations and finite element analysis of large deformation simulation method,use the cabinet flange as the main research object,analyze the deformation of transformer tank lifting process.The analysis shows,Increase the thickness of the lower cabinet flange and rearrange the bolts reasonably,transformer cabinet flange can enhance the ability to resist deformation,thus reducing the gap between the cabinet flange and reducing the amount of corrugated cabinet flange surface deformation.This conclusion can provide theoretical reference for transformer tank design.
