内容概要

The Yangtze River Three Gorges Project
is a remarkably big project. After genera- tio of research, survey,
planning, designing and cotruction by Chinese people, the 700MW
hydro- generator units have been italled in Three Gorges Project,
Which is a significant breakthrough. 454 pictures were selected
from te of thousands of cotruction pictures and a few hundreds of
videos showing the beauty of mechanical and electrical itallation
project for the book. The itallation process ofALSTOM 700MW
hydro-generator unit with words and pictures. It includes brief
introduction on three gorges project, turbine itallation, generator
itallation. This is a practical and readable book for students and
teache in college and worke in this industry.

章节摘录

版权页：   插图：    Safety guard should set up around the pit at elevation 75.3 and the working platform forthe stator,the height of the guard should conform to the safety regulations.Warning signs should be put up as well.Safety net should be used at the inside of the platform to avoid falling. When assembling the parts of the stator frames,fix the first part with steel ropes,chain blocks and other means until it is been assured for stabilization before set free fromthe crane hook.For the subsequent parts,insert all the coupling bolts and make it is stable,before loosening from the crane hook. The platform for the roundness measuring device should be firm and solid; all theopenings should be blocked to avoid falling.When moving the measuring arms up anddown,check for obstacles to avoid damaging the dial gauges. Carbon dioxide arc welding shall be used for the stator frame and the dovetail keys,good ventilation should be guaranteed against hazard gas such as monoxide may generatedue to high temperature of the welding.All the spatters should be cleaned and polished with flat chisel and angular grinders after the welding. Before the stacking of the stator laminations,clean and paint the inner surfaces of thegenerator pit and cover the top with shroud; it may be opened temporarily for the lowering of the laminations.And set up heaters and dehumidifiers to create good environments ofdirt-free,constant temperature and humidity. When installing the dovetail keys,the jacks and C-clamps should be fixed stably toprevent from falling.The platforms for each layers of the ring plates should be fixed firmand solid and be connected,safety guard should be set up at the sides. When stacking,gloves should be worn.Rubber or epoxy hammers shall be used withcare for the alignment of the stator core stacking.No metal hammers should be used directly to the stator core. Safety guards and warning signs should be employed when carrying out the statorloop test.Before the test,make thorough cleaning of the stator core,stator frame with vacuum cleaner and flour dough.Check the insulation of the exciting cable,which shall be protected with rubber pads.All the test equipments should be well earthed.
