The test results were better than the International Electrotechnical Commission standard requirements, marking the successful development of the first green hydrogen converter transformer with the world's largest capacity and representing the highest technical level of my country's converter transformers. This milestone achievement not only highlights China Xidian’s strength in energy technology innovation, but also injects new impetus into global green energy development. Strengthened simulation calculation leads the industry technology. This product design uses the independently developed nationally leading simulation calculation platform to conduct detailed simulation verification of the design plan, solving the problem of "stray losses and local overheating caused by large currents on the valve side of the non-co-directional and anti-parallel structure", "analysis of the winding impulse voltage wave process of the main modulation connection structure" and "with "Harmonic winding current distribution", "Calculation of wire cake loss and hot spot temperature rise", "High-frequency excitation inrush current tolerance calculation under frequent switching of photovoltaic power supply", "Calculation of coil short-circuit force with phase-shifting windings" and many other technical problems have opened a new chapter in the gigawatt-level "green hydrogen" project transformer and represent the highest level of domestic products of the same type. Refined process control and manufacturing excellence In the production process, Xidian Zhongte has repeatedly formulated risk prevention and control plans, and organized procurement, quality inspection, technology and other departments to conduct detailed reviews of key suppliers to ensure the quality of raw materials and components. From the careful preparation of quality control plans, to on-site manufacturing supervision of key components, to quality inspections of the production process, the entire production chain achieves consistent goals and sincere cooperation, responds to orders, strictly implements them, and does a good job in production control and quality control in all links. Consolidating resources to ensure the success of the test To ensure the smooth progress of the product test, Xidian Zhongte's test department upgraded the test equipment in advance and configured two variable frequency power supplies of 1600kVA and 50kVA. At the same time, the temperature rise test of this product is very special. The technical department designed and produced the tooling required for various tests such as temperature rise short-circuit copper bars and water cooling systems to ensure the successful completion of each test project. Through continuous exploration and practice, Xidian Zhongte has gradually created a more advanced and complete full-process project management and control system. The successful development of this product not only fully demonstrates China Xidian’s core competitiveness in the field of power transmission and transformation equipment, effectively promotes the high-quality development of the “One Belt, One Road” initiative, and opens a new chapter in gigawatt-level green hydrogen converter transformers, it is also a vivid manifestation of China Xidian’s active response to climate change and the promotion of green energy development. It also contributes to the promotion of the utilization of renewable energy and the development of green hydrogen energy.
