Abstract
The present invention discloses intermediate and high speed large capacity water-turbine generator set rotor. It contains magnetic pole, magnet yoke, rotor spider, principal axes, wherein said magnetic pole including pole coil with heat radiation turn and helical insulation supporting board, pole core with pole endplate, damping winding and damping ring connected by thin red copper piece. The present invention has advantages of fine radial ventilation among rotor spider, magnet yoke and magnetic pole, fine unit assembly heat radiation and stability of vibration.
Description
Technical field
The present invention relates to a kind of high speed large capacity hydroelectric generating set rotor.
Background technology
Rotor is the rotating part of hydraulic generator, is made up of parts such as main shaft, rotor field spider, yoke, magnetic poles usually, in order to produce magnetic field, transformation energy and transmitting torque.In the big high rotating speed hydraulic generator of capacity, the rotor speed height can bring many technical barriers such as bearing shell temperature rise, equipment acoustic noise are big, stability of vibration difference, and its rotor causes a large amount of heatings particularly outstanding because of the high speed machine motion.
Summary of the invention
The object of the present invention is to provide a kind of high speed large capacity hydroelectric generating set rotor, this rotor structure is the part of axle system and ventilating system.Axle system is made up of generator amature body, generator's motor shaft, hydraulic turbine macro-axis and runner, and rotor field spider, yoke and magnetic pole constitute the pressure source of radial ventilation, and the unit heat radiation is good, stability of vibration is good.
The objective of the invention is to be achieved through the following technical solutions: a kind of high speed large capacity hydroelectric generating set rotor, comprise magnetic pole, yoke, rotor field spider and main shaft, magnetic pole comprises pole coil, pole core, the new construction of reshaping after four welded corner joints of pole coil employing copper bar, and be provided with the heat radiation circle, radiating condition is improved, effectively reduce coil temperature rise 6-8 ℃, turn-to-turn adopts the F class F insulation.The upper and lower side of pole coil adopts the integral die spirality insulation supporting plate of F level, and they and coil are hot pressed into one, make the mechanical performance and the electric overall performance large increase of magnetic pole.After coil is inserted in iron core, between insulation supporting plate and pole end-plate pole shoe and with the magnetic pole shell feed plate between have 18 dielectric pin to be connected.
Pole core is repeatedly pressed by the cold rolling quality steel plate of 1.5mm and is formed, and the pole end-plate boots portion at two ends is a pyramidal structure, and pressing plate is the forged steel processing structure, and pole core compresses by pull bar.
Magnetic pole is equipped with longitudinal and transverse damping winding, and damping ring connects at the brace that adopts the multi-layer thin copper sheet to make between pole end-plate and the pole core and between the damping ring.Therefore the damping ring design has designed magnetic pole compressing tablet and magnetic pole dististyle at the pole core two ends between pole end-plate and pole core.
Yoke is overrided to form through punching out by the low-alloy high-tensile structural steel plate again, laminates whole in the building site.
For the globality that improves yoke and make stretching screw stressed evenly, reduce to be subjected to shearing, increase friction between sheet, adopted the interlace folded mutually method of a pole span of interlayer, compress with the segmentation of instrument screw rod, tighten up with the formation one with the high strength tightening bolt at last.
The yoke axial height is 1800mm, is provided with 6 wide radial ventilation slotted vanes of 40mm and goes one as little ventilation gap at the magnet yoke blanking sheet seam crossing, and they are united as the needed air channel of the closed circuit ventilation cooling system of generator with rotor field spider.Yoke and rotor field spider adopt and radially block key connecting.
In the bottom of yoke, dismountable braking ring is housed, braking ring fastens screw rod by yoke and yoke tightens up, and by nut support, regulates level with adjusting pad between braking ring and the yoke.Upper/lower terminal in yoke is provided with the rotation choke plate.
Rotor field spider is the disc type Welding Structure.
Main shaft adopts forged steel 20SiMn to make, and main shaft and rotor field spider are at the building site hot jacket together.
Advantage of the present invention is that rotor field spider, yoke and magnetic pole formation radial ventilation are unobstructed, the unit heat radiation is good, stability of vibration is good.
