As we have learned, our country from 20 centuries 70 time begin to develop form of large wind electric machinery, below the support that just takes wind to plan " in national " to 1997, move toward the market from scientific research. But because lack basic research to accumulate,wait for a reason with the talent, the ability of own research and development of report of our country wind is not worth badly, wind phone equipment is designed and make a level lag behind quite, still be in the level that dog and recommends foreign advanced technique on the whole.
At present although our country had mastered 750 kilowatt the wind cable unit of the following capacity is overall make a technology with the design of component and realized batch to produce, but this is equivalent to on international 20 centuries only level of 90 time medium-term. Production company of equipment of phone of our country major wind still stops in in low end the design of equipment and production level, and aircrew of constant frequency of speed change of homebred million made of baked clay stage still is being developed, million covers with tiles class lamina, gear case and dynamo are small lot production only. "Current, the wind cable unit of our country is controlling the component respect such as lamina of system, bearing, fan, gear case to be put in bigger supply and demand to contradict. Although development of industry of whole wind cable is rapidder, but manufacturer of wind phone equipment in this respect apparent productivity is not worth, cover with tiles in million especially extremely in the wind cable unit of the capacity, bearing and electronic-controlled the system does not have productivity almost. "Advanced and advisory Lu Kun expresses research center of industry of energy of Sai Di adviser, on the whole, research and development of technology of domestic wind cable still shows weakness, growth of chain of wind cable industry is not perfect, wind phone equipment is produced can insufficient, equipment of large wind phone counts an import badly, these are the main factors that restrict development of industry of cable of our country wind.
Xie Changjun of general manager of company of group of dragon source electric power says frankly, manufacturer of equipment of domestic wind phone still exists in development a lot of problems, if maturity of product of the technology between the enterprise and industrialization process difference are bigger, core technology level and own innovation ability are relatively inferior still. And, grow as homebred aircrew run time, the quality issue that by experience inadequacy brings also begins to appear, like what because design blemish,bring about gear case tine ruptures, because hydrogen is contained in material the quantity is exorbitant the main shaft that bring about ruptures etc.
In the meantime, all the time since the phenomenon of the " of light component of " reforming aircraft that exists in the industry brings about structure of product of existing wind report unreasonable still continueing.
