Transformer txias feem ntau yog siv cov roj transformer, tseem hu ua insulating roj los yog ntxhia roj. Transformer roj yog ib hom roj ntxhia-raws li cov roj tsim tshwj xeeb rau kev siv hauv hluav taws xob transformers. Nws ua haujlwm rau ntau lub hom phiaj, suav nrog hluav taws xob rwb thaiv tsev, cua txias, thiab tiv thaiv oxidation.
Transformer roj muaj lub zog dielectric siab, txhais tau tias nws muaj cov khoom siv hluav taws xob zoo heev. Nws pab tiv thaiv hluav taws xob tawg thiab arcing nyob rau hauv lub transformer. Tsis tas li ntawd, cov roj transformer muaj cov khoom siv hluav taws xob zoo, tso cai rau nws kom ua tau zoo dissipate tshav kub uas tsim los ntawm transformer cov tub ntxhais thiab windings.
Hom tshwj xeeb ntawm cov roj transformer siv tau tuaj yeem sib txawv nyob ntawm daim ntawv thov thiab kev tsim cov transformer. Feem ntau siv cov roj transformer muaj xws li cov roj ntxhia, uas yog cov roj ua kom zoo dua qub, thiab tsawg dua, cov roj hluavtaws xws li roj silicone lossis ester-based roj. Txhua hom roj muaj nws tus kheej zoo thiab cov yam ntxwv, tab sis cov ntxhia roj tseem yog cov feem ntau siv txias thiab insulating roj rau transformers.
