Evaporative cooling hydro-generator set in the Three Gorges Power Station successfully run
The evaporative cooling hydro-generator developed by the Chinese Academy of Sciences to provide key technologies has been put into operation successfully and the power output reaches 700,000 kilowatts. In the 10% overload condition, the unit's operating temperature is stable at 58-60 ° C, while the conventional unit's temperature is as high as 90-100 ° C. It is the first 700,000-MW evaporative cooling unit in China and the largest evaporative cooling in the world Turbine generator set, with completely independent intellectual property rights, indicates that China's power generation equipment technology and capacity level reached the world's leading level, is our country's large-scale development of independent research and development of major power equipment, a significant progress! Evaporative cooling technology effectively solves the bottleneck problem of heating and cooling of large-scale and giant hydro-generators and provides a powerful and reliable guarantee for the research and development and application of giant hydroelectric generators on the order of 1000 MW and above that are being planned by the country. On December 15, 2011, the world's first 700 MW hydroelectric generator with evaporative cooling technology, the No.30 underground power station of the Three Gorges Project, has been successfully integrated into the power grid. The second one was completed and put into production in July 2012. Hydrogenerator self-circulating evaporative cooling technology schematic diagram. The technology has no pump self-cycle, safe and reliable operation, the basic maintenance-free features. Compared with the whole air cooling technology, the coil temperature is low and distributed evenly, which can significantly extend the motor insulation life and save materials. Compared with the water cooling technology, medium dielectric properties, low system operating pressure, which can greatly improve the safety and reliability of the motor. Material of blind box packaging:
The material of the blind box packaging is generally 350 grams of coated paper, because the blind box packaging is a one-time consumer product, so the material does not need to be selected too well. The commonly used 350 grams of coated paper, four-color printing, and the surface coating choose matte film Just do
Blind box packaging is generally used in video game city lottery draws. Because it is a one-time product, many customers will not choose too good materials to make it. The commonly used copperplate paper printing film is just fine. Most of them are used in some lottery activities. At present, the most commonly used in China is to sell directly in the vending machine, which is very practical~
