75 kVA Roj-Immersed Transformers rau Tropical Climates: Corrosion thiab Cooling

Cov kev sib tw tseem ceeb ntawm huab cua sov

Kev nyab xeeb huab cua ntawm cov teb chaws Es Xias Qab Teb thiab cov cheeb tsam zoo sib xws, cov yam ntxwv ntawm qhov kub thiab txias, cov av noo siab, salinity siab nyob rau hauv cov ntug dej hiav txwv, thiab dej nag hnyav, ncaj qha ua rau cov hlau xeb thiab cuam tshuam cov cua sov ua kom zoo. Cov kev hem thawj tseem ceeb yog electrochemical corrosion los ntawm cov av noo thiab ntsev, kev ua haujlwm tsis zoo ntawm cov khoom siv hluav taws xob los ntawm cov huab cua ntub dej, txo cov cua sov dissipation efficiency ntawm qhov kub thiab txias, thiab pwm thiab kev loj hlob ntawm cov kab mob hauv thiab sab nraud.

Multi-Txheej Corrosion Protection System

Ib qho chaw sov sov-tsim 75 kVA roj-immersed transformer siv ntau- qib kev tiv thaiv. Cov txheej txheem thiab cov khoom siv yog sandblasted rau qib Sa2.5 thiab coated nrog hnyav -lub luag haujlwm los tiv thaiv -corrosion system, feem ntau yog epoxy zinc- nplua nuj primer, epoxy mica hlau oxide nruab nrab lub tsho tiv no, thiab polyurethane topcoat nrog tag nrho cov zaj duab xis qhuav thickness 5 micrometers. Rau ib puag ncig ntug hiav txwv huab cua, cov ntaub thaiv hlau tsis muaj steel lossis kub -dip galvanized daim hlau muaj. Sealing siv siab -kev ua tau zoo silicone roj hmab gaskets thiab sealants ntawm npog, bushings, thiab li qub, ua tiav qhov kev tiv thaiv mus txog IP55. Sab hauv, lub tshuab ua pa nrog silica gel lossis molecular sieve desiccant absorbs noo noo los ntawm huab cua nkag mus rau hauv lub tank, thiab lub tank sab hauv tuaj yeem coated nrog roj- pleev xim.

Txhim kho Thaum tshav kub kub Dissipation thiab Temperature Rise Control

Kev ua kom muaj cua sov kom zoo yog qhov tseem ceeb hauv qhov chaw siab - qhov kub thiab txias. Lub tshuab cua txias siv corrugated tso tsheb hlau luam lossis vaj huam sib luag- hom radiators, uas muab qhov chaw txias txias dua li cov tsoos tubular radiators rau tib lub ntim, nrog cov radiator fins tau txais tib yam los tiv thaiv- xeb txheej los yog siv txhuas fins. Optimized internal oil duct tsim txhawb kev ncig ntawm cov roj transformer. Tsawg-tsim tsim siv siab- silicon steel zoo txo ​​qhov tsim hluav taws xob ntawm qhov chaw, thiab tus qauv tsim suav nrog cov npoo txaus tshaj qhov ntsuas kub nce siab, piv txwv li 65 K, ua kom cov cua kub kub nyob hauv qhov txwv tsis pub muaj kev nyab xeeb txawm nyob rau qhov kub thiab txias tshaj 40 degrees C. Cov cua txias tuaj yeem ntxiv rau qhov ntsuas qhov kub thiab txias.

Kev xaiv cov khoom siv thiab cov txheej txheem tshwj xeeb

Cov ntaub ntawv rwb thaiv tsev siv cov qib siab - qib aromatic polyamide ntawv lossis DMD rwb thaiv tsev rau kev txhim kho cua sov thiab noo noo. Cov roj transformer yog siab -kev ua tau zoo naphthenic ntxhia roj los yog hluavtaws ester kua, tom kawg muab siab dua noo noo kam rau ua thiab superior oxidation stability. Tag nrho cov ntsia hlau sab nraud thiab cov txiv ntoo yog kub-dip galvanized lossis stainless hlau. Coils tau txais lub tshuab nqus tsev kom qhuav thiab impregnation kom tshem tawm cov dej noo, chav ua tiav yog ntim nrog cov roj insulating hauv qab lub tshuab nqus tsev kom tshem tawm cov npuas npuas, thiab cov kev ntsuam xyuas ntawm lub Hoobkas suav nrog kev ntsuas nruj thiab cov kev ntsuas tawm ib nrab ntxiv rau cov kev kuaj niaj hnub.
