People's power transformer research and development of the largest capacity transformer

A large-capacity power transformer housing was put on line in the welding plant of Jiangxi People’s Power Transmission and Transformation Company. This SFSZ11-240000/220 power transformer is a large-capacity 220kV product independently researched and developed by the company. Its capacity is 240MVA. It is one of the largest capacity transformers produced by the domestic transformer industry.

The engineering and technical personnel of the People's Power Transmission and Distribution Company rely on the existing design strengths to extensively gather the latest information resources, draw on the latest technology and latest technologies of domestic and foreign transformer designs, boldly use patented technologies with independent intellectual property rights, and scientifically apply a number of The industry's top technological achievements. Through a series of intelligent experiments and experiments, computer software technology was used to assist in design, calculation, and check. After comparison of multiple projects, the best choice of electromagnetic calculation scheme and the best structural form were finally determined. To ensure product quality, One-off product test successfully provided a reliable guarantee.

Recently, the company's special project research team has been established, product design has been completed, part of the shell has been put into production. Production preparations for cores, coils, and insulation are also underway.

This product has high quality performance such as low loss, high efficiency, low noise, and short circuit resistance. After successfully passing all the tests, the product once again proved that the 220kV transformers of the people's power transmission and transformation have reached the international advanced level.
