Description
Technical field
The utility model relates to generator cooling technology fields, evaporate in particular to a kind of rotor of vertical machine
Cooling device.
Background technique
Mainly have to the type of cooling of generator at present: air cooling, internal water cooling and evaporation cooling.Air cooling refers to utilization
Air blows over stator and rotor winding as cooling medium and iron core surface exchanges heat, and absorbs heat by the specific heat of heat transfer and air；Water
Interior cold finger directly circulates cooling water to the inside of stator and rotor winding, absorbs heat by the specific heat of heat transfer and water；Evaporation cooling refers to use
Height insulation, low-boiling fluorocarbons are cooling medium, pass through evaporative cooling medium phase transformation absorption, heat transfer.
The most important type of cooling of hydrogenerator is cold to stator and rotor winding and the progress of iron core surface using air
But.In the case where electromagnetic load is constant, the linear dimension of motor increases with the increase of capacity motor；At the same time, electric
The growth rate of machine heat dissipation area is but much smaller than the growth rate of the loss of electric machine.In order to guarantee that the temperature rise of motor is unlikely to excessively high,
Intensity of cooling must correspondingly increase.Although the capacity of fully air cooled hydrogenerator constantly rises with advances in technology,
Air cooled ability increasingly tends to the limit, must be by the cooling technology of the big motor of higher capacity so air is cooling
Significantly more efficient method is replaced.Intensity of cooling can be largely improved instead of air as cooling medium with hydrogen,
But the motor of hydrogen_cooling needs to make the purity of hydrogen to be higher than specified value, this brings difficulty to design and installation；In addition, close
Envelope Explosion-Proof is a hidden danger of hydrogen_cooling motor safe operation always.The cooling effect of water inner cold motor is excellent, motor
Electromagnetic load can be designed more cooling than air and hydrogen_cooling motor will be high, while material can more effectively be made
With, therefore large capacity hydroelectric generator mostly uses the mode of internal water cooling to improve capacity limitation；In addition to this, water inner cold motor is fixed
The running temperature of rotor windings is not only low but also uniform compared to air cooled scheme, is more conducive to the health operation of motor；So
And the problems such as water inner cold motor can not be avoided that structure is complicated, maintenance load weight, pipeline parts blocking, water leakage；In addition, non-pure
Net water is conductor, and short-circuit risks caused by water leaks all cannot be neglected in all electrical equipments.Evaporation it is cooling it is nontoxic,
Other component that is pollution-free, not corroding metal and motor has good cooling capacity and high insulation, fire prevention, arc extinction performance, can
The generation for inhibiting electric fault overcomes using the latent heat of vaporization heat exchange efficiency of fluid is high, winding temperature rise is low, without hot-spot
Internal water cooling operating pressure is high, leakage will cause badly damaged essential weakness；And fan is eliminated by cold mode in the inner, from
And declining wind friction loss, 0.1~0.2%, and convenient operating maintenance can be improved in gross efficiency, saves material, safe and reliable to operation.
Evaporative cooling motor avoids blocking, the risk of leakage of water inner cold motor while keeping inner-cooled machine advantage.
Evaporation cooling technique be absorbed using the latent heat of phase change of cooling medium, heat transfer.Because the heat exchange efficiency of phase-change heat-exchange is high
In heat convection, so its cooling effect will be apparently higher than air-cooled, the hydrogen-cooled and internal water cooling to exchange heat using specific heat heat absorption
Equal cooling technologies.The cooling hydrogenerator of the evaporation used has been put into and is all made of stator evaporation cooling, rotor air cooling
Scheme；Application for rotor evaporation cooling technique, still among research.

Technology uses the pole coil of hollow core conductor coiling, the import and export of hollow core conductor by pipeline be connected to condenser out, import
On, condenser is looped around in shaft, provides cooling water in such a way that axis side intakes for condenser.By verification experimental verification, the party
The recurrent state of case is normal, and cooling effect is fine.Simultaneously be proposed for for rotor cooling circuit, box structure be preferably,
But the paper and the specific embodiment that box structure is not described further.
Cooling scheme, the i.e. structure of long pipeline cooling circuit are evaporated using the rotor of the prior art, there are two can not avoid
The shortcomings that:
First disadvantage Producing reason is the program using runner of the hollow core conductor as evaporative cooling medium, constitutes magnetic
The electromagnetic wire of polar curve circle usually requires to wind many circles around pole core, and so the hollow core conductor on each magnetic pole is very
It is long；Two meters of the model diameter mentioned in aforementioned paper, it is necessary to which 11.9 meters of long electromagnetic wires, such interminable runner are in addition big
The corner of amount forms very big flow resistance, this is unfavorable for the evaporative cooling system without pump self-loopa.
Second disadvantage Producing reason is that the condenser of the program is placed in inside motor, and using water as cold source；Though
A possibility that right condenser is fixed on around shaft, the centrifugal force very little being subject to, but water leaks still has, and cannot advise completely
Keep away short-circuit risks caused by water leaks.
