Hope to engage in the transformer predecessors to answer. I hope you help me introduce a little more recommended information better
Oil-immersed power transformer is one of the company's leading products, the original Ministry of Machinery Industry planning in Shandong Province, 220kV and below the production of the only key power transformers. Product voltage level 6 ~ 220kV, capacity 30 ~ 360000kVA, including 23 series, more than 200 varieties, more than 1,400 kinds of specifications, the technical performance indicators all meet the national standards and the International Electrotechnical Commission standards. The company has designed and manufactured the first domestic 110-kilovolt 31500 kVA three-coil aluminum transformer. Since the 1982 production of 220kV transformer, the product has been used in sunshine, Taizhou, Jiangxi and many other national key projects
I have seen the 220kV power transformer minimum 63MVA, the largest 250MVA, there is no such specification is not clear, it is estimated that small and small is not where to go, and then big is not where to go for reference The
GB GB / T6451 made a detailed provision, the latest version of the 2008 revision. (Boost, buck), three laps without load (boost, buck), autotransformed (boost, buck), the two-lane, There are several types of auto-load (boost, buck) and so on, there are about 31.5,40,50,63,90,120,150,180,240,370,400 MVA several grades, but corresponding to different types of transformers, Capacity level is slightly different, do not know what type of capacity you ask the range?
