Recently, two sfpll-400000/110 power transformers, undertaken by the west power plant and independently developed by the west power plant, have passed various supervision tests of the quality inspection and testing center of electrical equipment in the power industry.
This product is the largest transformer in the series of 110kV voltage grade power transformers developed and manufactured by western power co., LTD. It has the characteristics of large capacity, high impedance and large magnetic flux leakage. Therefore, how to reduce the product loss produced by large capacity, high impedance, guarantee the product performance requirements of the temperature rise and mechanical force, at the same time solve with large capacity, high voltage, large size of products transportation problem has become the key technical difficulties. Therefore xd often change in the introduction, absorption and digestion of previous product technology, on the basis of the magnetic flux leakage control, to reduce the stray and eddy current loss and so on the many kinds of technology integration in 110 kv products, forming a new set of design scheme of data obtained through product test validation, the result is good.
As state grid reform and the implementation of saving energy and reducing consumption policy, high voltage, large capacity, low loss, will gradually become the future development direction of the transformer, large capacity, high impedance, low loss transformers also will become the market mainstream products. In the research and development of this product, the first application of the high-leakage magnetic control treatment technology of the super-large capacity product in the l10kV voltage grade series products has been realized. The successful development of it, the larger capacity for the future of high impedance transformer accumulated valuable data and experience in energy saving design, xd often change for the future development of large capacity of 220 kv, 330 kv products laid a solid foundation, at the same time as the market development provides a strong support.
