Mga Espesyal na Solusyon para sa Transformer na may Pagsasaayos ng Struktura at mga Advanced na Proseso
Ⅰ. Pangunahing Hamon at Paglalakbay sa Inobasyon
Ang mga tradisyunal na transformer ay limitado ng struktural na redundancy, bottlenecks sa performance ng materyales, at hindi sapat na precision ng proseso, kaya hindi ito nasasagot sa mga demand sa espesyal na mga scenario (halimbawa, may limitasyong espasyo, mataas na panganib ng short-circuit, at masamang kapaligiran). Ang solusyon na ito ay nagpapahusay ng performance at adaptability sa scenario sa pamamagitan ng 3D structural optimization, cutting-edge material upgrades, at precision process innovations.
