Rotor is placed inside turbine generator startor. This operation is essential for turbine shaft line assembling.
Rotor`s weight is 110 t. Gap between the rotor and internal stator shell is 35 mm. As a result special slinging procedure and rails for moving the rotor into the stator were required.
Installation staff to perform the task successfully completed similar works at the first power unit of LNPP under construction. Therefore, the operations were smoother and faster this time.
Following rotor placing, rotor wobbling within the bearings will be measured. When this task is completed, the rotor should be removed from the stator to perform a number of tests and measurements, including high voltage test of generator startor winding.
