On the morning of December 16, 1000kV single-phase double-winding power transformer (DFP-265MVA / 1000kV) independently developed by Changzhou Toshiba Co., Ltd. of Shandong Electrical and Electric Group passed the new product technology appraisal.
The new product technology appraisal meeting, organized by the China Electricity Council in Changzhou, from the China Electricity Council, the State Grid Corporation of China, Beijing Institute of Electrical Technology Machinery Industry and other units of the leading and well-known transformer industry experts, and Shenhua Victory Power Plant and other user representatives were invited to attend the appraisal meeting.
The appraisal committee composed of 14 experts listened to the product development report, reviewed the appraisal data and carried out on-the-spot sampling and conducted a comprehensive evaluation of the products from the aspects of product performance, application of new technologies, process tooling, product technical level and the like, Product performance indicators of the test in line with GB / T1094 and other technical requirements and product specifications, product design advanced, reasonable structure, the company tooling and equipment, complete testing means to meet production requirements, the main technical performance indicators reached the international advanced level of similar products, Agreed to pass the product technical appraisal.
1000kV single-phase double-winding power transformer is a new product independently developed by Changzhou Toshiba and the world's first high-voltage coil split, single-phase voltage regulator coil 1000kV double-winding power transformer is a new product for Shenhua Shengli Power Plant.Victory power plant using two Machine tower, five towers in one design, the implementation of the UHV long-distance power transmission, power plant outlet for 1000kV, technical difficulty is great.
The face of arduous challenges, the company pay close attention to the optimization of technical equipment parameters, design verification program, the confirmation of the test program and the entire process of quality control, has repeatedly organized thematic seminars on the technical level of insulation, 1000kV outlet and other technical problems in-depth discussion. Based on the successful integration of TOSHIBA high-voltage transformer technology and the successful development experience of the 2 million UHV prototype, the safety, reliability and advanced technical solutions have been finally determined. The transformer is different from conventional power transformers in that the voltage of the high voltage coil is 1000kV UHV, And the high-voltage coil is split. The voltage regulator coil is built-in separately and the structure is more complicated. Therefore, a new coil arrangement structure is adopted and a new insulation structure is developed. The fuel tank adopts a new structure so that the product has the advantages of small transportation size, Superior performance and other characteristics to ensure that the product can be 42 degrees below zero temperature in the safe operation.
According to Changzhou Toshiba official said that the product passed the new product technology appraisal, marking the Changzhou Toshiba in the path of scientific and technological innovation go further, in the design of UHV transformer, large-scale production, quality assurance system And other areas to a new height, fully demonstrated the company in high-end power equipment manufacturing technology and ability to further enhance the business in the field of high-end power equipment R & D and manufacturing core competitiveness and innovation for the future of new products , New technology R & D to provide experience and data support for the continuous surpassing of new technologies and new heights, to create a higher level, greater capacity of the UHV products has laid a solid foundation for promoting the transformation and upgrading of enterprises, reform and innovation, management provide A strong guarantee.
