Cov roj pleev xim rwb thaiv tsev, tseem hu ua xim pleev xim rwb thaiv tsev lossis cov roj pleev xim, ua lub luag haujlwm hauv kev rwb thaiv tsev, tiv taus dej noo, tshem tawm cua sov, thiab kho hauv cov transformers siab.
Raws li lawv cov tshuaj sib txawv, cov roj rwb thaiv tsev tam sim no tuaj yeem muab faib ua peb pawg: polyester raws li; Resin chav kawm; Siliceous cov ntaub ntawv. Polyester rwb thaiv tsev roj feem ntau yog npaj los ntawm cov tshuaj tiv thaiv condensation ntawm polyols thiab polyacids, thiab feem ntau yog cov kua tsis muaj xim lossis daj daj. Nws muaj lub zog tawg siab thiab ntim resistivity, uas tuaj yeem tiv thaiv tam sim no kom tsis txhob hla dhau thiab muab kev rwb thaiv tsev zoo. Nws muaj qhov pheej yig tshaj plaws ntawm peb hom roj rwb thaiv tsev thiab yog cov roj rwb thaiv tsev siv ntau tshaj plaws hauv cov transformers siab.
Txawm li cas los xij, cov roj rwb thaiv tsev polyester muaj viscosity siab, thiab nws cov viscosity raug cuam tshuam los ntawm qhov kub thiab txias. Qhov viscosity nce ntxiv ntau ntawm qhov kub qis, uas cuam tshuam rau nws cov fluidity thiab cov cua sov dissipation effect. Yog li ntawd, thaum siv, feem ntau yuav tsum ntxiv cov diluents kom txo qhov viscosity ntawm cov roj rwb thaiv tsev, tswj kom muaj fluidity zoo, thiab xyuas kom meej tias lub transformer siab tuaj yeem raug immersed tag nrho thaum lub sijhawm immersion. Qhov hnyav tshwj xeeb ntawm cov roj rwb thaiv tsev polyester thiab diluent feem ntau yog nyob ib puag ncig 0.9, uas tuaj yeem kuaj los ntawm lub ntsuas hnyav tshwj xeeb.
Qhov thib ob, cov roj polyester insulating feem ntau yuav raug oxidation thiab degradation ntawm qhov kub siab, tsim cov tshuaj acidic thiab sludge, uas cuam tshuam rau kev ua haujlwm ib txwm ntawm cov khoom thiab txwv nws qhov kev siv ntau hauv qhov chaw kub siab. Tsis tas li ntawd, piv nrog cov roj resin thiab siliceous insulating, cov roj polyester insulating muaj cov nqi dielectric poob tangent siab dua, uas txhais tau tias lub zog poob ntau dua nyob rau hauv cov teb hluav taws xob hloov pauv thiab yuav cuam tshuam rau qee qhov kev ua haujlwm zoo ntawm cov khoom.
Tam sim no, cov roj rwb thaiv tsev polyester feem ntau siv rau kev impregnating windings, xws li high-frequency transformers, motors, cables, thiab lwm yam, uas tuaj yeem txhim kho qhov rwb thaiv tsev, thermal conductivity, thiab noo noo tsis kam ntawm cov khoom thiab ntev lawv lub neej kev pabcuam. Cov roj rwb thaiv tsev ua los ntawm cov resin feem ntau yog tsim los ntawm cov organic polymer compounds, feem ntau yog kua lossis khoom, nrog kev tiv thaiv zoo hnav.
Cov roj rwb thaiv tsev uas ua los ntawm cov resin tuaj yeem tsim los ntawm kev kho qhov sib piv ntawm cov khoom siv raw thiab cov xwm txheej ua haujlwm kom tsim cov kua roj resin uas muaj viscosity qis dua. Cov kua no muaj cov khoom zoo thiab cov khoom txheej, thiab feem ntau tsis tas yuav ntxiv cov tshuaj ntxiv. Hauv qab cov xwm txheej cua sov, cov roj rwb thaiv tsev uas ua los ntawm cov resin kuj tuaj yeem ua kom mos lossis yaj. Piv nrog cov roj rwb thaiv tsev polyester, cov roj rwb thaiv tsev resin muaj kev ruaj khov dua, kev ua haujlwm rwb thaiv tsev hluav taws xob zoo dua, thiab tus nqi siab dua. Nws feem ntau siv rau kev rwb thaiv tsev ntawm ntau yam transformers, cov qhov hluav taws xob, thiab cov pob qij txha. Cov roj rwb thaiv tsev siliceous feem ntau yog tsim los ntawm cov organic silicon compounds xws li polydimethylsiloxane. Nws feem ntau yog cov kua tsis muaj xim lossis daj daj nrog viscosity qis heev thiab fluidity zoo.
Piv nrog cov roj rwb thaiv tsev polyester thiab resin, cov roj rwb thaiv tsev siliceous muaj cov nqi dielectric poob qis dua, kev poob zog me dua nyob rau hauv cov teb hluav taws xob hloov pauv, thiab kev ua haujlwm ntawm cov khoom zoo dua. Nws kuj muaj kev tiv thaiv arc zoo thiab kev tiv thaiv to, thiab tuaj yeem tswj tau qhov ua tau zoo ruaj khov hauv cov chaw ib puag ncig hnyav. Cov roj rwb thaiv tsev siliceous tuaj yeem siv rau kev rwb thaiv tsev hauv cov chaw ib puag ncig hnyav xws li hluav taws xob siab, kub siab, av noo siab, thiab txias heev, txhim kho qib rwb thaiv tsev thiab kev ua haujlwm ntawm cov khoom. Nws qhov chaw kub hnyiab siab thiab cov khoom tua tus kheej muab cov roj rwb thaiv tsev siliceous muaj txiaj ntsig zoo hauv kev nyab xeeb hluav taws. Txawm li cas los xij, cov roj rwb thaiv tsev siliceous muaj tus nqi siab dua thiab feem ntau tsis siv rau hauv cov transformers siab zaus.
