The first highest voltage transformer was successfully developed

It was learned from Hebei Baoding Tianwei Baochang Electric Co., Ltd. that the world’s first highest-voltage ODFPS 1GVA / 1000V AC transformer , developed by the company, passed all tests on the afternoon of the 16th , and Its various performance indicators have reached the international advanced level.

It is understood that this product has completely independent intellectual property rights and core technologies, mainly including auto-transformer, voltage regulator, and low-voltage voltage compensator. The voltage regulator transformer and the main transformer are connected through the copper busbar, which greatly simplifies The structure of the main transformer, this structure and electromagnetic principle is still the first case at home and abroad.

Experts of the expert group participating in the trial stated that UHV transmission technology and corresponding equipment manufacturing technology are currently cutting edge technologies in the field of electric power technology and electrical equipment manufacturing in the world, and the UHV transmission line power is five times that of the 500 kV line. However, the power loss is only a quarter of its total cost. The successful development of this product is a major breakthrough in the development of China's major power equipment manufacturing industry.

According to Ding Qiang, Chairman of Tianwei Baobian Electric Co., Ltd., after years of independent innovation and technological breakthroughs, the company achieved a major turning point in China's transformer manufacturing companies from tracking to leading the world's advanced technology trends. The successfully developed transformer will be put into use in the world's highest voltage level and most challenging power grid project, Jindongnan - Nanyang - Jingmen UHV AC pilot demonstration project.

It is reported that the development of UHV power grids can successfully solve the problem of insufficient transmission capacity and land resources in China's existing 500 kV grid, and is a major research project that has been incorporated into the national long-term science and technology development plan and the revitalization of the equipment manufacturing industry.
