HORIZONTAL HYDRO GENERATOR
RENOVATION AND MODERNIZATION
The scope of hydro generator reconstruction includes replacement of obsolete active parts, namely:
- core of the stator of large electric machines with the assembly of active steel in a ring;
- stator winding (replacing the insulation, allowing to increase the capacity of the hydrogenerator by up to 10%);
- poles of the main generator rotor.
Modernization and reconstruction of the mechanical part of the generator:
- cooling system of stator and bearing units, namely: oil coolers (replacement of copper pipes with cupronickel ones), air coolers (using finned tube, which allows increasing the cooling surface area);
- generator bearings (replacement of babbitt coating with fluoroplastic one, allowing to reduce wear of working surface and heating temperature);
- of the thrust (conversion from hydraulic support to rigid support, this eliminates the use of the hydraulic system and leaks in the chamber of the thrust);
- replacement of the metal coating of the thrust bearing segments with metal-fluoroplastic coating.
