摘要

通过对真空灭弧室的结构优化、波纹管的设计和制造工艺、屏蔽筒的固定方式以及灭弧室装配工艺等影响灭弧室机械寿命的因素进行分析、研究

在此基础上重点对波纹管的结构、材质、加工工艺、表面处理、焊接方式以及灭弧室设计中存在的失效隐患加以改进

并将改进后的研究成果应用在TD14A-12/1600-31.5C真空灭弧室上

配合ZN28-12K/T1250-31.5断路器在开距11mm下顺利完成10万次机械寿命试验

达到了预期的目的。

Abstract

In this paper

the factors influencing the mechanical endurance of vacuum interrupter（VI）

such as optimization of the structure

design and manufacture technology of bellows

fixing methods of shielding tube

and assembling technology of VI etc.are analyzed.The bellows is improved in several aspects

the structure

material

manufacturing technology

external treatment

and welding method.Besides

the defects in VI design are also advanced.The results are used in TD14A-12/1600-31.5C vacuum interrupter

and the VI has passed 100000 times mechanical endurance test successfully.
