Recently, Shandong Electrical Engineering & Equipment Co., Ltd., a subsidiary of China Electric Equipment, successfully developed the CRAFT NNBI ±400 kV isolation transformer for the Institute of Plasma Physics. After testing, all parameters of the transformer exceeded relevant standards and technical specifications, fully demonstrating the company's strong Zmogljivosti R&D na polju opreme UHV .
As the world's first ±400 kV three-phase integrated AC-DC isolation transformer, it will serve the Comprehensive Research Facility for Fusion Technology (CRAFT). This transformer effectively isolates the 10 kV AC from the grid side and the ±400 kV high potential on the high-voltage DC side, providing crucial power support for China's nuclear fusion research.
Shandong Electrical Engineering & Equipment Co ., Ltd ., se je soočil s tehničnimi izzivi na področju višjega cenovnega razreda, ki je uskladila z glavnimi strateškimi potrebami države ., ki je oblikovala namensko raziskovalno skupino in se nenehno lotila ključnih tehničnih težav {{4}, ki jih je pridelala ključne tehnične težave {{4} {4}. Načela inovacij, učinkovitosti in odličnosti, ki aktivno spodbujajo vrhunski, inteligentni in zeleni razvoj električne opreme . z vrsto tehničnih poudarkov, je ta izdelek uspešno premagal številne industrijske izzive, kar kaže na izjemno tehnično moč .
In terms of insulation design, the transformer has addressed the primary longitudinal insulation challenges of AC-DC isolation transformers, ensuring reliable insulation performance under high-voltage conditions and providing a solid foundation for the safe and stable operation of the equipment. At the same time, through precise leakage magnetic control technology, it effectively optimizes electromagnetic performance, reduces losses, and improves the overall efficiency of the Oprema, ki jo dopušča, da deluje varno in stabilno pod zapletenimi delovnimi pogoji .
The self-cooling and temperature rise control of complex insulation structures is another major technical breakthrough of this product. By solving this challenge, the design ensures effective heat dissipation under high load conditions, thereby extending the service life of the equipment. In addition, the transformer has successfully resolved the spatial layout challenges of the ±400 kV valve-side bushing in the three-phase integrated structure and neodvisno razvil napravo na strani ventila, optimiziral strukturo opreme in izboljšal njeno funkcionalnost, kar je pokazalo močne neodvisne inovacijske zmogljivosti .
Kar zadeva zmožnosti tolerance, ima transformator visoke AC in DC vzdrži napetostno raven, kar mu omogoča, da se prilagodi ekstremnim napetostnim pogojem in izpolnjuje stroge zahteve raziskovalnih naprav za jedrsko fuzijo za električno opremo .
Uspešen razvoj ± 400 kV trifaznega integriranega izolacijskega transformatorja AC-DC ne samo odraža tehnično moč Kitajske električne opreme v UHV opremi, ampak tudi močno podpira kitajske raziskave jedrske fuzije, ki napreduje v razvoju višjega cenovnega moči v državi .
