Abstract


At present , the global power transformers market prospect is broad . China 's electric power development in recent years very rapidly . The total installed power capacity of 500 million kilowatts in 2005 exceeded 600 million kilowatts in 2006 , the annual growth in the amount equivalent to the total installed capacity of power generation in India . In addition, from a global point of view , from the Third World countries to developed countries into the most need electricity . Of 2 / 3 of the energy from the energy distribution and energy demand is mainly concentrated in the central and western regions , while the eastern part of the total electricity demand in China accounted for 2 / 3 of the total power generation in China . To solve the contradiction between China's energy demand is relatively uneven distribution concentrated , high-voltage transmission is particularly important . In the transmission mode , the most mature technology is still AC transmission . For each additional one kilowatt installed capacity in the high-voltage transmission process , the installed capacity of the transformer is necessary to increase the power generation capacity of 5-8 times . These conditions for the development of transformer equipment industry to create a once-in-a-lifetime opportunity . Optimized transformer products , cost-effective , so that the manufacturer's products more competitive , thereby increasing the strength of the company . SFZ10-50000/110 type power transformers of 110kV transmission and transformation network has a very typical , and thus to optimize the design of this product has a very good practical . However , transformer manufacturers in China , compared with the well-known suppliers in Europe and the United States , and labor and time-consuming , high cost of contradictions have become increasingly prominent . To solve this problem , the authors believe that as a transformer designers on the one hand to do the data accumulated for the past design information , digestion and absorption of foreign experience , and more to do with the times , continuous improvement process, continuously improve the manufacturing level , and strive to on design innovation . The SFZ10-50000/110 transformer optimal design , the distribution of the electric field , the impact , multi- program on the basis of the calculation of the magnetic flux leakage electromagnetic calculations . From dozens feasibility program to select the best . Production trial , the optimized design of products applied high voltage winding shielded core miter joints of new technology , to maximize cost- optimized products .
