在三峡左岸电站的14台机组中,第一批机组将于2003年安装完毕投产发电。现在三峡左岸电站开始进入机组安装施工的高峰时期。由于厂房内安装场地的面积问题,使定子不能按照常规的施工布置在安装场组装,而要在机坑内组装。本文介绍选定用作定子组装场的机坑及其分别组装的定子;提出对两次选定用作定子组装场的机坑方案的看法。
Among the 14 units in the Three Gorges Left Bank Power Station, the first units will be installed and put into operation in 2003. Now the left bank of the Three Gorges Hydropower Station began to enter the peak period of installation and construction. Due to the problem of the area of the installation site in the factory, the stator can not be assembled in the installation site according to the conventional construction layout but assembled in the machine pit. This article presents the machine pits selected for use as the stator assembly yard and their separately assembled stators; the view of the two pit pits selected for use as the stator assembly yard is presented.
