Recently, China Xidian successively developed two 750-kV and 72-million-kVA three-phase non-excitation voltage regulator power transformers for Shaanxi Qinling Power Generation Co., Ltd. The successful development of these two products signified that China’s Xi’an Electric Co. The transformer has made major breakthroughs in its own innovation, promoted the upgrading of product technology levels, improved the company's core competitiveness, and accumulated rich experience for the development and transportation of larger transformers in the future.
The two three-phase integrated power transformers with the highest voltage levels in the world are the heaviest transformers in road transport. Xidian, which undertook this development task, belongs to Xidian West Transforming Technology Co., Ltd. on the basis of making full use of the existing ultra-high voltage giant transformer design and manufacturing technology, and carrying out technological innovation and scientific research on key technical and technical difficulties. In view of this product's high voltage level, large capacity, and difficulty in transportation, the electric field, magnetic field, thermal field, mechanical strength, etc. are accounted for and studied, and the product performance, quality, and reliability are improved through optimized design to ensure that each index meets Claim. At the same time, corresponding process plans and process documents have been formulated and advanced production equipment and tooling have been purchased to ensure the reliability and safety of manufacturing.
The two 750 kV and 72 kV three-phase non-excitation voltage regulator power transformers have the advantages of novel structure, reasonable performance, advanced performance, low loss, reliable operation and easy maintenance. They are safe, reliable, energy-saving and environment-friendly products. At present, 3 utility model patents and 1 proprietary technology have been applied for.
