Baoding Tianwei Baobian Electric Co., Ltd. (hereinafter referred to as Baobian Electric) revealed today: On October 26, a new type of high-voltage direct out 1 million KVA/1000 kV AC UHV transformer independently developed by China was successfully tested in Baobian Electric under the joint witness of representatives of State Grid Corporation of China, China Electric Power Research Institute and specially invited experts. The test data shows that all technical indicators and performance indicators have reached the world's leading level, indicating that China's ultra-high voltage transformer technology has once again made a leading breakthrough.

The new 1 million KVA/1000 kV AC ultra-high voltage transformer adopts the 1000kV lead direct out structure for the first time, canceling the 1000kV lead disassembly and on-site reassembly before the product leaves the factory, preventing the quality risk of disassembly and separate transportation, and reducing the difficulty of on-site installation; A new explosion-proof oil tank design is adopted to improve the anti explosion performance of the product; The magnetic shielding structure is optimized and stray loss is greatly reduced. The development and application of a number of innovative technologies have realized the upgrading of UHV transformer technology and quality, providing reliable quality assurance for UHV products to pass the first test, be put into operation successfully and operate safely for a long time.

Under the joint witness of the representatives of State Grid Corporation of China and specially invited experts from China Electric Power Research Institute, the product passed all factory tests at one time, and all test indicators met the technical requirements. The success of this product is a revolutionary and leading breakthrough for the transformer manufacturing industry, especially in ultra-high voltage AC products.

As the key link of China's new energy supply and consumption system, the stability, security and reliability of the ultra-high voltage field are particularly critical. The successful test of a new high-voltage direct out 1 million KVA/1000 kV AC UHV transformer not only improves the safety and stability of AC transformers in China, but also plays an important role in clean energy consumption and ensuring the stable operation of the power grid.
