On November 19, at present, the 1000 kV 400 MVA single-phase generator step-up transformer with the largest capacity of 1000 kV in China has been successfully developed in one time by the Company's subsidiary Xidian West of China Electric Power Group. The index meets or exceeds the requirements of national standards and technical agreements and is a UHV transformer for 2 × 1000 MW project of Shaanxi Longyuan Power Plant Co., Ltd., Zhao Shiban of Shaanxi Energy Power Co., Ltd. The successful development of the products has further enhanced the brand name of XD The technical strength in the field of UHV step-up transformers has accumulated valuable experience for the follow-up development of UHV step-up transformers and consolidated and upgraded the leading level and leading position of XGTC in UHV transmission equipment.
In recent years, power generation industry continue to improve the efficiency of power generation, and actively promote clean power generation.In recent years, product technology has developed rapidly, 1000 kV power transformers due to their long distance power transmission capacity and other characteristics, has gradually become the construction of many power plants Preferred product.
Based on the existing national standard, based on the existing design and manufacturing technology of 1000 kV transformers of the company, the West-West transformation in accordance with the relevant provisions and requirements of the technical agreement, in view of this product capacity, high voltage level, large weight , Large volume, strict requirements of loss and difficulty of transportation, further technical innovation and scientific research are conducted on the overall structure of single-phase 1000kV single-phase generator step-up transformer to optimize the electrical design and internal insulation structure, , Loss, temperature rise, insulation performance, etc. The product has the advantages of compact structure, small material consumption, light weight, small volume, low noise, energy saving and environmental protection.
