Recently, the single-phase generator step-up transformer with a 1000-volt-voltage 400-megavolt-ampere single-phase generator with the largest capacity of 1,000 kilovolts of domestic voltage was successfully developed in China at one time. The product's performance indicators meet or exceed the requirements of national standards and technical agreements. The successful development of the product further enhances the technical strength of the XD brand in the field of UHV step-up transformers, accumulating the subsequent development of UHV step-up transformers. Valuable experience.
In recent years, with the power generation industry actively promoting clean energy power generation, the 1000-kilovolt-class power transformer has gradually become a preferred product for many power plant construction because of its long-distance power transmission and large transmission capacity.
In 2016, Xidian Electric Co., Ltd., a subsidiary of China Xidian Electric Power Co., Ltd., undertook the task of developing an ultra-high voltage transformer for the 2×1000 MW project of the Shaanxi Leishanwan Power Plant. Based on the current national standard, based on the design and manufacturing technology of the existing 1000-kilovolt class transformer, the company is targeting this product with large capacity, high voltage level, large weight, large volume, strict requirements for loss and difficulty in transportation. Challenges: Further technical innovation and scientific research on the single-phase 1000 kV single-phase generator step-up transformer's overall structure, optimization of electrical design schemes, internal insulation structures, and comprehensive impedance, loss, temperature rise, insulation performance, etc. Systematic calculations. It ensures the product's compact structure, low material consumption, light weight, small size, low noise, energy saving and environmental protection.
