Advantages of the company
The company provides services for modernization on-site equipment installation with reissue of operational documentation. It is possible to perform the small-scale modernization and export the equipment to our own production facilities for work performance.
Unique services
- Processing the shafts of the rotor shaft at the power plant conditions;
- Complex diagnostics of turbogenerators with determination of optimal modernization measures;
- A comprehensive proposal for the installation of a frequency drive with the modernization of engines;
- Modernization of the monitoring system.
Stator modernization
- Replacement of winding;
- Replacement of active steel;
- Modernization of fastening of frontal parts and lead busbars of winding;
- Modernization of the fastening of collectors (replacement of rigid fastening with elastic ones);
- Replacement of the outer core packages with improved cooling;
- Replacement of pressure rings of the core with improved cooling;
- Restoration of core pressing;
- Modernization of the thermal control system of the winding with the transfer of resistance thermometers to the distillate drains from the rods;
- Replacement of rigid outgoing busbars with flexible ones;
- Installation of additional sensors for monitoring the level of partial discharge, vibration, degree of deformation of the front parts;
- Modernization of water and hydrogen seals.
Rotor modernization
- Replacement of the rotor winding;
- Replacement of housing and interturn isolation with increasing class of heat resistance;
- Replacement of the damper system;
- Installation of the control system of the winding closures and the temperature of the cooling gases in the air gap;
- Modernization of the current supply and contact rings;
- Replacement of bundles of the shroud rings for corrosion-resistant, made of forgings of non-magnetic steel grade P900;
- Processing of working surfaces of post bearing and UVG with a decrease in beats up to 0.02 mm.
In the process of modernization, modern materials are used with a high level of reliability, the possibility of recycling and characterized by a low level of aging during operation, which allows increasing operational reliability and minimizing the scope of inspections / repairs. The part of the components after the tests (defectoscopy) and recovery is reused.
The effect of performing a complex of works on the modernization of the turbogenerator.
- Extended service life up to 30 years;
- Increase in reliability;
- The possibility of reliable operation in the mode of daily load regulation;
- Reduction of the terms of typical overhauls during operation;
- If necessary, increase the power to 15%;
- Possibility of reliable operation in the mode of reactive power consumption;
- Significant reduction in costs compared with the purchase of a new turbogenerator.
