1.Ua rau koj xav tau
Transformer Hom thiab Loj: Txiav txim siab hom tshwj xeeb thiab qhov loj ntawm transformer koj tab tom ua nrog. Cov transformers sib txawv (piv txwv li, kev faib tawm, lub zog, lossis tshwj xeeb transformers) yuav xav tau ntau hom ntawv rwb thaiv tsev.
Kev khiav hauj lwm tej yam kev mob: Xav txog qhov kev khiav hauj lwm kub, humidity theem, thiab ib puag ncig tej yam kev mob uas lub transformer yuav siv. Cov yam tseem ceeb no yuav cuam tshuam rau hom ntawv rwb thaiv tsev uas koj xav tau.
2. Hom ntawv rwb thaiv tsev
Ntawv-raws li rwb thaiv tsev: Feem ntau ua los ntawm cellulose (xws li, kraft ntawv), nws yog dav siv rau nws zoo rwb thaiv tsev zog thiab nqi-zoo. Haum rau feem ntau tus qauv transformers.
Composite Rwb thaiv tsev: suav nrog kev sib txuas ntawm cov ntawv nrog lwm cov ntaub ntawv xws li polyester lossis resin. Muab cov khoom zoo xws li thermal stability zoo dua los yog dej tsis kam.
Pressboard: Ib hom tuab, nruj ntawm cov ntaub ntawv rwb thaiv tsev siv rau hauv cov ntawv siv hluav taws xob ntau ntxiv rau lub zog thiab kev tiv thaiv.
3. Cov ntsiab lus tseem ceeb los xav txog
Dielectric Strength: Qhia cov ntawv muaj peev xwm tiv thaiv hluav taws xob tawg. Lub zog dielectric siab yog qhov tseem ceeb rau high-voltage transformers.
Thermal Rating: Txheeb xyuas qhov kub siab tshaj plaws uas cov ntawv rwb thaiv tsev tuaj yeem tiv taus yam tsis muaj degradation. Xyuas kom meej tias nws phim lossis tshaj qhov kub ntawm koj lub transformer.
Moisture Resistance: Ntsuam xyuas daim ntawv tsis kam rau cov dej noo nqus, uas tuaj yeem cuam tshuam rau nws cov rwb thaiv tsev ua haujlwm. Xav txog cov dej-resistant los yog hydrophobic xaiv rau qhov chaw ntub dej.
Thickness thiab Density: Xyuas kom cov ntawv tuab thiab ntom ntom ua tau raws li qhov yuav tsum tau ua ntawm koj lub transformer tsim rau kev rwb thaiv tsev txaus thiab kev txhawb nqa.
4. Zoo thiab cov qauv
Ua raws li Cov Qauv: Xyuas kom cov ntawv rwb thaiv tsev ua raws li cov qauv kev lag luam thiab cov ntawv pov thawj (xws li IEC, ASTM). Qhov no guarantees zoo thiab kev ntseeg siab.
Chaw tsim tshuaj paus Reputation: Yuav los ntawm cov tuam txhab muaj koob npe paub txog kev tsim cov khoom siv rwb thaiv tsev zoo. Tshawb xyuas, ntawv pov thawj, thiab cov khoom lav.
