In industrial turbines, in LP blades, the resonant vibrations have high amplitud es due to the thin sections of the blades, and the large lengths. Products manufactured include power transformer s, instrument transformers, dry type 3 transformers, series — and stunt reactor, capacitor tanks, vacuum — and SF circuit b reakers gas insulated switch gears and insulators.
This is due to the rubbing friction between the component under considerat ion with any other object. The number of layers or thickness of insulation depends on the machine voltage. The casing is heavy in order to withstand the high pressures and temperatur es. The inner cage is usually fixed in the yoke by an arrangement of spring to damper the double frequency vibrations inherent in two pole generator.
This insulation is void free and possess better mechanical properties.
High tension ceramic, Insulation Plates and bushings Respect for dignity and potential of individuals. Rotor is inserted in the stator and assembly of end shields, bearings etc.

The need for a damping element is therefore eliminated. About project SlidePlayer Terms of Service. The pilot exciter is a PMG permanent magnet generator. Generator is to be loaded within a very short period. Skip to main content. Bottoming cycles, for instance, extract fluid energy that is at a lower pressure and hariswar than a turbine in a conventional power plant.
The steam passes through the stationary nozzles and is directed at high velocity aga inst rotor buckets causing the rotor to rotate at high speed. At their ends, the slots traiing are short circuited through the rotor body. The following even ts take place in the nozzles: The frictional damping has a particu lar characteristic.
BHEL is today the largest engineering enterprise of its kind in India, with a well-recognized track record of performance making profits continuously since LK blades ha ve 3-fork roots for all sizes. Temperature detector and other device installed or connected within machine, permit the windings core and hydrogen temperature, pressure, and purity in machine.
Because of the expanding flow, higher volumetric flo w 18 occurs at the turbine exit at least for compressible fluids leading to the nee d for larger turbine exit areas than at the inlet.
The slot wedges are made up of high electrical conductivity material and thus act as damper winding. R is subdividing the frame and axial members to form blok from which the cooling given to end from radial duct in the core and is recirculated. Steam generator up to MW unit size. BHEL as a part of Pt.

All AC machines rated for more than 5 MVA or with armature core longer the machine is to be provided with at least 6 resistance thermometers of their couples which shall built inside the stator suitably distributed among the circumference at the likely hottest point. Its high traiing, low density, and good erosion resistance m ake it a good candidate for high speed or long-last stage blading.
Log In Sign Up. In hariwdar periodically varying excitation force, it may frequent ly happen that the force is less than the friction force. Under this collaboration agreement BHEL has established strong design manufacturing and servicing base for units up to MW ratings. As compared to electrolytic copper silver alloyed copper features high strength properties at high temperature so that coil deformations due to thermal stresses are eliminated.
In such cases, where it is not poss ible to avoid resonance, a damping element is to be used in the LP blades to red uce the dynamic stresses, so that the blades can operate continuously under reso nance also.
This insulation shows only a small increase in dielectric dissipation factor with increasing test voltage.
