Description

Logical inclined beating type hydro-turbo generator and work method thereof in a kind of efficient excitation of umbrella-type
Technical field
The present invention relates to hydroelectric facility field, particularly relate in a kind of efficient excitation of umbrella-type logical inclined beating type hydro-turbo generator and Its work method.
Background technology
Hydroturbine generator can be divided into impulse turbine and the big class of reaction turbine two by operation principle.Impact type water The runner of turbine is rotated by the impact of current, and in work process, the pressure of current is constant, mainly the conversion of kinetic energy；Counterattack The runner of the formula hydraulic turbine is rotated by the counteracting force of current in water, and in work process, the pressure of current all can have with kinetic energy Change, but mainly pressure can conversion.
Impulse turbine, owing to its active wheel only part crosses water, part bucket stress, therefore such hydraulic turbine necessary flow Less, relatively it is suitable for the generating place of low discharge high water head.Impulse turbine, can be divided into by the flow direction of current and cut the formula of hitting (again Claim bucket-type) and tilt-impulse type two class, under the conditions of isometrical water wheels, the stress arm of force cutting the formula of hitting is relatively big relative to tilt-impulse type, but runs Water wheels rotating speed is relatively small.
Inclined-jet turbine, owing to its vane stress is less relative to the vane stress of tangential wheel, the material to blade Matter and manufacturing process require relatively low and stable, noise is little, overall cost performance is higher, deeply by domestic and international small hydropower station enterprise Hobby.
But, the problem existing for existing inclined-jet turbine is: the 1) impeller of the hydraulic turbine and electromotor and excitation electricity Machine need to be by longer transmission shaft driven, and generally, the installation for the ease of power transmission shaft is changed, the meeting of power transmission shaft junction Use Flange joint, simultaneously in order to maintain power transmission shaft stable rotation, it is to avoid eccentric rotary, can be at the junction of rotating shaft and middle part Multiple bearing is set, bearing increase the friction energy-dissipating that can strengthen in rotation process, bearing easily burns out because of temperature arrising caused by friction, and relatively When eccentric rotary occurs in long power transmission shaft, it is easily caused and electromotor is caused damage；2) electromotor of existing hydroturbine generator and Exciter can produce substantial amounts of used heat (mainly by heavy current heat production in wire and bearing pivoting friction heat production) at work, needs Special heat radiation, cooling system are installed, when heat radiation, cooling system go wrong, are easily caused movement, bearing burns out, and Even and if under cooling system normally works, owing to stator and rotor are that inside and outside layer is distributed, be positioned at that the rotor of internal layer produces is useless Heat need to be transmitted to the external world by stator and rotor every space gap layer, and little every the heat conduction rate of space gap layer, internal layer rotor is with outer There is the bigger temperature difference in layer stator, internal layer rotor easily burns；3) existing inclined-jet turbine, owing to utilizing in water flow dynamic energy There is bigger water flow dynamic energy remaining, the utilization rate of water flow dynamic energy is relatively low, present stage, does more in inclined-jet turbine Preferably efficiency is only 80% to 84%；4) existing often group hydrogenerator is all the customization machine for different terrain, causes former Material, assembly, wire rod and parts can not be general, it is impossible to enough batch productions；5) due to the stator in hydrogenerator, turn The parts such as son, salient pole, power transmission shaft need to bear the stress of higher temperature or bigger, its stator, rotor, salient pole, power transmission shaft etc. Parts require height to the strength of materials；6) magnetic pole of Exciting Windings for Transverse Differential Protection is only capable of utilizing a wherein magnetic pole, and excitation efficiency is relatively low, excitation energy consumption Bigger.
Above-mentioned factor causes bigger input cost and production management's cost to the construction in power station, and power station produces production capacity Relatively low, the small-sized available hydraulic power potentials of part is wasted.
Additionally, the mode of work-doing of existing inclined-jet turbine is all: nozzle to be perpendicular to the radial manner of turbine blade, There is certain inclination angle with the inletpiston of folding shape blade in the high-velocity flow of nozzle, high-velocity flow enters along inletpiston, and flows Through the folding shape face of blade, being delivered on blade by its kinetic energy, last current go out from water outlet surface current；This kind of mode of work-doing, it flows out Current complementary energy relatively big, water flow dynamic energy transformation efficiency is on the low side；And kinetic energy loss is relatively big in the transmission process of its kinetic energy, generating efficiency On the low side.
Summary of the invention
The technical problem to be solved is: 1) in existing hydroturbine generator, power transmission shaft and bearing be due to stress relatively Greatly, friction produce temperature higher, its loss is bigger；2) electromotor and the exciter of existing hydroturbine generator can produce greatly at work The used heat of amount, needs to install special cooling system, and the cooling effect of its cooling system is not good enough, easily burn movement；3) existing There is the efficiency of inclined-jet turbine only 80% to 84%, the most on the low side；4) existing hydrogenerator is all for different terrain Customization machine, there is larger difference in volume, it is impossible to enough batch productions；5) stator in hydrogenerator, rotor, salient pole, transmission The parts such as axle require height to the strength of materials；6) excitation efficiency of Exciting Windings for Transverse Differential Protection is relatively low.
