Xidian Changchang Jinbei Converter Station ±200kV converter transformer passed the test
Recently, Xidian has become the first ±200kV converter transformer manufactured by the Jinbei-Nanjing ±800kV UHV DC transmission project of the State Grid Corporation in Jinbei-Nanjing, and all the data are superior to the technical agreement. It marks that Xidian Changchang has taken a new step in the field of DC power transmission and transformation, and will be more mature in the research and development and manufacturing of commutation.
In the operation, the converter transformer not only has to withstand the high-voltage AC voltage on the grid side, but also withstands the high DC voltage of the converter valve in the polarity reversal. It has a very complicated and strict assessment of the electric field of the transformer. In order to fully complete the product manufacturing tasks, the project is under the unified command of Xidian Group and relies on the transformer industry R&D platform for joint design. The first ±200kV converter transformer passed all the tests at one time, indicating that the West Electric constant change has mastered the core technology in the field of low-end commutation, which also laid a solid foundation for the future to the higher end commutation field, and Accumulated valuable experience.
The Jinbei-Nanjing ±800kV UHV DC Transmission Project (referred to as the Jinbei Project) has 7 sets of ±400kV and 7 sets of ±200kV converter transformers. It is a UHV converter transformer project that is independently contracted by Xidian Changchang. It is the core project of the transformation and upgrading of 2016 and the improvement of quality and efficiency. Faced with the increasingly complex and fierce market environment in the power transmission and transformation industry, the company has always adhered to the goal of manufacturing quality products, equipping power, and enhancing core competitiveness and brand influence. At the same time, in the follow-up product design and manufacturing process, we continue to adhere to the fine tradition of meticulous organization, careful design, meticulous manufacture and careful management, laying the foundation for the creation of national excellent projects.
