Solusyon ng Espesyal na Transformer na May Mataas na Resistensya sa Pagsabog
Pagtukoy ng Pangunahing Hamon
Sa mga kritikal na aplikasyon tulad ng pagpapakilos ng barko, pagbibigay ng lakas sa trakisyon ng riles, at malalaking kagamitan sa pagmimina, ang mga espesyal na transformer ay patuloy na nasa gitna ng dalawang banta:
- Pag-uugnay ng Elektriko: (impact ng short-circuit current >100 kA, rate ng harmonic distortion >30%, voltage surges/sags sa lebel ng millisecond)
- Pag-uugnay ng Mekaniko: (patuloy na pag-usbong ng vibrasyon >5g, instant shock >15g).
Ang mga tradisyunal na disenyo madalas nagdudulot ng hindi maaaring ibalik na pagkasira tulad ng plastic deformation ng winding, pagkakabali ng insulation layer, at displacement ng core. Ang solusyon na ito ay nagpapakilala ng mga pagbabago sa struktura sa pamamagitan ng sistemikong inobasyon.
