Product Description

10.5KV Turbine Electric Generator QNP:

A steam turbine generator is a device that uses steam to rotate a turbine generator to produce electricity.Steam turbines use water that is heated to extremely high temperatures and converted into steam to rotate the blades of a turbine, in order to create mechanical or rotational energy.  

This rotational energy caused by the high pressured steam turbine is used to generate electricity in an attached generator. Steam turbine generators require an outside fuel source to heat water into the steam needed for electric production.

QNP`s steam turbine generator can adopt static silicon controlled excitation, two-pole AC brushless excitation and three-pole AC brushless excitation.

Characteristic and Performance of Generator main parts

Stator consists of base, stator core and stator windings.
The base is welded by steel plate, the structure is light and sturdy, and the base is divided into many air inlet and outlet zones in the axial direction;

Stator coil:
It is stacked by strands of copper wire covered by polyester glass fiber, with half-unit type and basket shaped structure (parts of stator coils use transposition structure). The insulation grade of the stator coil is F grade. The stator coil is shaped by continuous wrapping and mould pressing with mica tapes. The coil end is firmly tied up to the support and the bundling ring with unidirectional tapes or dacron-glass ropes thus the turbo-generator unit became highly resistant towards sudden short-circuit conditions. 
Stator core:
Stator core is punched and stacked by cold rolled non-oriented, high permeability, low loss high-quality silicon steel sheet, both sides of the silicon steel sheet are coated with a solid insulating film to prevent short-circuit between the stator core pieces to reduce eddy current loss.

The rotor is composed of shaft, coil, center ring, shroud ring and fan ring etc. The rotor coil is made of cold-drawn flat copper wires, and processed by oxygen-free annealing. The rotor coil of generator with 50MW and above is welded together by silver-bearing cold-drawn copper wires and adopts F grade insulation. 

The shroud ring at rotor coil end is made of non-magnetic steel. Both ends of the rotor are equipped with centrifugal fan or axial flow fan with paddle fan blade which is forged by high-strength aluminum alloy.

Rotor machining:
The generator shaft is forged from an integral high-quality alloy steel and has an axial groove formed thereon for fitting a rotor coil and an air groove or a crescent groove is made in the large tooth to enhance the cooling of the main body and the coil end. The slots are processed by special machine for generator rotor processing, Tacchi high precision horizontal slotting and milling machine made in Italy, to ensure the high efficiency of generator. 

The generator rotor must be subjected to high-speed dynamic balancing experiment and dynamic impedance experiment before delivery to verify the mechanical strength of the rotor and ensure excellent inter-turn insulation of the rotor windings.
