1250 MW级核电汽轮发电机定子机座制造工艺

摘要

定子机座是汽轮发电机中外形尺寸最大的部件，起着固定、支撑及保护定子铁心的作用，在内部还构成了发电机整体通风冷却循环回路。定子机座在结构上还要满足固定、冷却、吊运及线路布置等功能，在使用和运输过程中的强度需要是汽轮发电机定子机座设计及制造的首先要求，文章介绍百万核电汽轮发电机定子机座的制造工艺。%Stator frame was the largest part in the turbine generator. It acted as the securing, supporting and protecting means to the stator core while it forming the integral ventilation cooling circulation inside the generator. Also, construction of the stator frame should meet with the functional requirements of fixing, cooling, lifting and line arrangement. The strength required by operation and transportation was the most important factor to the design and manufacture of the turbine generator stator frame. The manufacture and technology of stator frame of the MW class nuclear power turbine generator were introduced.
