Technical field
The present invention relates to a kind of wind-driven generator that adopts the vaporization cycle cooling, belong to technical field of wind power generator.
Background technique
As wind-power electricity generation the most ripe in the renewable energy technologies, for reply a large amount of use that traditional fossil fuel energy brought compel physical environment, social crisis at the tip of the brow, be a practicable solution.In worldwide, wind-power electricity generation is also developing just rapidly constantly, in in the past more than 20 year, the separate unit peak output of wind-driven generator is by original tens kilowatts of by now 2500 kilowatts, just the target towards 5000 kilowatts in unit strides forward, adopt the wind energy turbine set power of many set grid-connection generatings can reach gigawatt, become the important component part in the energy supply chain, and no longer be the dispensable additional energy.China is vast in territory, and wind energy resources is very abundant, and along with continuous progress in science and technology, the Economy of wind-power electricity generation is constantly improved, in addition China the important component part of renewable energy sources as China's energy strategy, wind-power electricity generation has enormous and latent market.
For the long-time running that realizes that wind-driven generator is efficient, stable, safe, need the necessary cooling method of configuration in wind powered generator system, work in certain temperature range to guarantee parts such as gear-box, generator and control frequency variator.At present forced air cooling and water-cooling pattern are generally adopted in the cooling of these parts, wherein forced air cooling is applicable to that power is lower than the small power generation unit of 750kW, and, then need adopt the mode of recirculated water cooling could satisfy the requirement of cooling off for the wind-powered electricity generation unit of power greater than 750kW.Along with wind power generating set further striding forward to the maximization direction, the heat that produces in its running will sharply increase, cooling system has been proposed more harsh requirement, the traditional type of cooling will be difficult to reach the demand of cooling, very be necessary to develop the wind powered generator system based on other type of cooling for this reason.
Summary of the invention
The purpose of this invention is to provide that a kind of refrigerating capacity is big, regulating power is strong, good stability, can satisfy the wind-driven generator of the employing vaporization cycle cooling of high-power cooling requirement.
It comprises stand, wind wheel, lower velocity shaft, gear-box, gear-box heat exchanger, high speed shaft, control frequency variator, control frequency variator heat exchanger, generator, generator heat exchanger, cooling medium heat exchanger, cooling medium, recycle pump, cooling medium intake pipe, cooling medium return pipe and cabin lid; It is characterized in that also comprising the outer evaporation circulating cooling machine of cabin lid that is arranged on, the cold of this evaporation circulating cooling machine manufacturing cools off by the cooling medium that the cooling medium heat exchanger passes in the cooling line, again by the cooling medium circular flow through gear-box heat exchanger, generator heat exchanger and control frequency variator heat exchanger, the heat that they produce is taken away, guaranteed the long-term work that wind power generating set is efficient, stable, safe.
Compare with forced air cooling, the water-cooled wind-driven generator of present employing, have outstanding advantages such as refrigerating capacity is big, regulating power strong, good stability, can satisfy high-power cooling requirement, lay the foundation for developing high-power wind-driven generator group of new generation.In addition, because refrigerator can provide lower chilling temperature, can provide wind-driven generator required optimum working temperature, thereby significantly improve wind-power electricity generation efficient.

Embodiment
According to shown in Figure 1, the wind-driven generator of employing vaporization cycle cooling of the present invention comprises stand 1, wind wheel 2, lower velocity shaft 3, gear-box 4, gear-box heat exchanger 5, high speed shaft 6, control frequency variator 7, control frequency variator heat exchanger 8, generator 9, generator heat exchanger 10, cooling medium heat exchanger 11, cooling medium 13, recycle pump 14, cooling medium intake pipe 15, cooling medium return pipe 16 and cabin lid 17; It is characterized in that also comprising the evaporation circulating cooling machine 12 that is arranged on outside the cabin lid 17, the cold that this evaporation circulating cooling machine 12 is made passes to cooling medium 13 in the cooling line by cooling medium heat exchanger 11, again by cooling medium 13 circular flows through gear-box heat exchanger 5, generator heat exchanger 10 and control frequency variator heat exchanger 8, the heat that they produce is taken away, guaranteed the long-term work that wind power generating set is efficient, stable, safe.
During wind-driven generator work, wind wheel 2 rotates under wind-drive, its rotating speed reaches gear-box 4 by lower velocity shaft 3 and carries out speedup, high speed shaft 6 through speedup connects with the rotor of generator 9 inside, drive rotor high-speed rotation and cutting magnetic line and produce electrical potential energy, meanwhile the frequency of supply that causes because of generator 9 fluctuations of speed when wind-force changes changes, guarantee that the electric power of delivering to power supply-distribution system satisfies the requirement of being incorporated into the power networks, also need to be equipped with 7 pairs of frequency of supplies of control frequency variator and automatically adjust.In above-mentioned generator set working procedure, gear-box 4, generator 9, control frequency variator 7 can produce a large amount of heats, if there is not suitable cooling method, will cause the serious consequence of burning when temperature surpasses certain limit.Work in the operating temperature range that allows in order to ensure these parts, guarantee the generator set safe operation, can gear-box heat exchanger 5, generator heat exchanger 10 and control frequency variator heat exchanger 8 be set respectively in gear-box 4, generator 9 and control frequency variator 7 outsides, will take away with the heat that upper-part produces by the cooling medium of each heat exchanger of flowing through.Cooling medium after temperature raises is through cooling medium heat exchanger 11, the cold that outer evaporation circulating cooling machine 16 is made with being arranged on the cabin lid carries out the exchange heat cooling, then each parts is carried out next round circulation cooling, thereby guaranteed efficient, stable, the safe long-term work of wind power generating set.
Compare with the wind-driven generator of present employing forced air cooling, water-cooled, though the expense and the refrigerator that adopt the wind-driven generator of vaporization cycle cooling to increase evaporation circulating cooling machine and each parts heat exchanger cool off needed energy consumption to cooling medium, but outstanding advantages such as it has, and refrigerating capacity is big, regulating power strong, good stability, can satisfy high-power cooling requirement, lay the foundation for developing high-power wind-driven generator group of new generation.In addition, because refrigerator can provide lower chilling temperature, therefore can guarantee the required temperature of wind-power generator maximal good speed row operating mode, significantly improve wind-power electricity generation efficient on the one hand, can also prolong the working life of equipment on the other hand, thereby reduce the maintenance expenses and the renewal cost of equipment, improved the Economy of wind-power electricity generation.
