Excitation regulator transformer test

Recently, the domestically produced 240,000 kVA, 750 kV single-phase non-excitation voltage regulator generator transformer passed all tests at one time, which marked another 750 kV single-phase non-excitation with completely independent intellectual property rights. The voltage regulator generator transformer was successfully established at Xi’an Electric Machinery Manufacturing Company. The test results show that this new product not only has advantages such as partial discharge and low noise, low temperature rise and low loss, but also its technical performance has reached the international advanced level. What's even more interesting is: Compared with imported equipment of the same type, The cost can be reduced by 20%-25%, becoming a truly “affordable” product, which greatly meets the supporting needs of domestic and foreign power transmission and transformation equipment, and at the same time brings to the domestic and foreign same-sector markets that have been slightly depressed by the financial crisis. A fresh air.

In order to reduce line losses, extend transmission distance, and reduce construction and operating costs, the transmission capacity of the power grid is constantly increasing. At present, the 750 kilovolt transmission has become the mainstream in the northwest region, and the matched generator transformer has also become an important product in the transformer market. The West Power Group, which is committed to "high, economical, and sharp" technologies, began to digest and absorb imported technologies from the 1980s onwards. It has mastered a 500-kilovolt transformer through technological innovations for key scientific research in foreign countries. The key technologies for reducing loss, noise, vibration, and partial discharge have achieved standardization of product structure and development of second and third generation products with high reliability. In 2005, Xidian Group developed the first UHV transformers and shunt reactors for China's first 750 kV power transmission project. In 2008, Xidian Group once again provided similar products for the second phase of the 750 kV power transmission and transformation project. On the basis of this, through further research on the key technologies of ultra-high voltage, XD Group has made bold innovations in the insulation structure of 750 kV generator transformers, high-pressure outlet structure design, fuel tank strength and shielding technology, and successfully developed this technology. High and new products with lower manufacturing costs. This fully demonstrates that with its own innovation, Xidian Group has completely mastered the design, manufacture, installation and commissioning of 750 kilovolt power transmission and transformation equipment, and is fully equipped with the ability to control the construction of 750 kV power grids.
