October 31, Baoding Tianwei Baosteel Electric Co., Ltd. for the world's highest elevation, the largest span, the most natural conditions of the most complex world-class transmission network construction project - Tibet and Changdu power grid network project - the Lancang River (Qamdo) 500 thousand V substation expansion project, independent research and development of the first 750MVA / 500kV site assembly transformer successfully shipped.
In the Sino-Tibetan networking project, Baosteel undertook the manufacturing task of two 750MVA / 500kV on-site assembly transformers for the expansion project of the Tibetan and Zhongdu power grids - the Lancangjiang (Qamdo) 500 kV substation project. Height of 3500 meters above the extreme temperature -45 ℃, with large capacity, high voltage, high altitude, day and night temperature difference, resistance to cold, transport difficulties and so on.
Compared with the single-phase and combined transformers commonly used in transport restricted areas, assembling transformers have the advantages of saving investment cost, compact body, low transportation weight, low transportation cost, small footprint, simple operation and maintenance, especially for our country The western region by the transport conditions or area restrictions on the power plant or substation, an effective solution to the needs of the restricted areas of transport power development.The successful development of the product to solve the three-phase transformer core frame and the whole phase of the decomposition of the coil, Site assembly and other technical problems, especially on-site core assembly, drying technology and other technologies to achieve a real short time, low energy consumption, precision, reached the world's leading level.
It is understood that the Tibetan network project by the Tibetan Tibet and Changdu power grid network project, Sichuan-Tibet railway Lhasa to Linzhi section of the power supply project, starting from the county of Changkang Mangkang County, stopped at Shannan Sangri County, across the three cities of Tibet Ten districts and counties, plans to build, expand 110 kV and above substation 16, the new 110 kV and above lines 2738 km. The project is following the 2011 Qinghai-Tibet, 2014 Sichuan-Tibet two transmission networking project put into operation, the third Construction of the ultra high pressure 500 kV power days.
The project from the first product R & D and manufacturing to the smooth shipping, change the electrical organization of a professional technical team and capable operators in a relatively short period of time to complete the production, highlighting the protection of electricity 'based on industry serve the country, cast the world brand' Of the historical sense of mission and sense of responsibility for the preservation of electricity in the ultra-high pressure on-site assembly transformer market has laid a good performance basis.
