二滩电站水轮机工艺研究

Study on Technology for Hydraulic Turbine of Ertan Power station

二滩电站是目前世界上在建的单机出力及总装机容量最大的水电站。６台水轮发电机组由加拿大ＧＥ公司总承包，哈电公司分包其中的一台。该机组设计结构新颖，制造工艺难度较大，本文详细介绍了二滩电站水轮机主要部件的加工工艺。

Ertan power station is the largest waterpower station which is being built about the single power and the total power in the world. GE company of Canada is the contractor for all the 6 units of hydraulic turbine and generator, and HEC is a subcontractor for one unit. The structure is so novel that is very difficult in manufacture. In this paper, we introduce in detail the manufacture process and technology of the main parts of Ertan hydraulic turbine.
