本文就水轮发电机组直缸型接力器套管产生永久性变形的原因,应用材料力学的组合变形理论进行了分析;提出了增强接力器套管抗压强度的三个方案,并进行了比较,从中筛选出了最优方案。
In this paper, the causes of the permanent deformation of the straight cylinder type recoiler casing of hydroelectric generating set are analyzed and the theory of combined deformation of material mechanics is analyzed. Three schemes to enhance the compressive strength of the casing of the relay are proposed and compared , From which the best program was screened out.
