3000 Kva Roj- puv Transformer

Cov3000 kVA Roj Immersed Transformerkhij lub ntsiab lus nkag mus rau hauv qeb "Hnub Nruab Nrab". Thaum nws tuaj yeem teeb tsa rau kev faib tawm dav dav, nws feem ntau yog tsim los rau cov ntawv thov kev lag luam tshwj xeeb uas tus qauv qis - voltage txwv dhau.

Raws li tus hwmdielectric kua filling transformer, chav tsev no yog tsim los ua haujlwm siab -flux density. Tsis zoo li cov khoom me me uas tso siab rau corrugated elasticity, 3000 kVA units feem ntau muaj qhov nruj, tsis yog - nthuav dav tank qauv ua ke nrog rau sab nraudConservator Tank. Cov qauv no tso cai rau kev tswj xyuas ruaj khov ntawm cov ntim loj ntawm cov kua dej dielectric (kwv yees . 2000+ liters) nthuav dav hauv cov khoom hnyav.

Txij li lo lus tseem ceeb yog"Dielectric kua", peb muab kev yoog raws li tus qauv ntxhia roj. Rau tej yaam num uas yuav tsum tau muaj kev nyab xeeb hluav taws kub (xws li, sab hauv tsev muaj substations los yog offshore platforms), qhov nodielectric kua filling transformertuaj yeem ua tau retrofilled nrogSynthetic lossis Natural Esters (K-Class fluids).

• Hluav taws kub Point: Esters have a fire point >300 degree, piv rau ~ 170℃rau cov roj ntxhia.
• Kev tswj dej noo:Lub conservator system yog nruab nrog aSilica Gel Breatherlos yog kev saib xyuas - dawbRubber Bag (Air Cell)nyob rau hauv lub conservator. Qhov no cais cov kua los ntawm huab cua ncaj qha, tiv thaiv oxidation thaum tso cai rau cov kua "ua pa" rau hauv ib qho chaw nthuav dav.

Ntawm 3 MVA, kev tswj xyuas tam sim no yog thawj qhov kev txwv kev lag luam.

• 690V Industrial Standard:Txhawm rau kom cov dej ntws tswj tau (~ 2500A), ntau 3000 kVA units raug mob rau690Vcov zis theem nrab. Qhov no yog tus qauv rau cua turbine kauj ruam - nce units thiab loj industrial variable speed drives (VSD).
• Kev sib tw 400V:Yog hais tias 400V tso zis yog nruj me ntsis yuav tsum tau, tam sim no surges mus approx.4 330 tzs. Hauv qhov xwm txheej no, qhov kev txiav tawm LV yog tsim tshwj xeeb nrog amulti-flange Busbar caj pas, tsim los ua phooj ywg nrog siab - ntsuas Copper Busducts, vim tias cabling yog lub cev tsis zoo.

Standard nta rau ib chav tsev ntawm qhov magnitude no muaj xws li:

• Buchholz Relay:Nruab nyob rau hauv cov yeeb nkab ntawm lub ntsiab tank thiab conservator, tshwj xeeb tshaj yog mus ntes roj tsub zuj zuj (me faults) los yog roj surges (qhov loj faults).
• Sib Nqus Roj Qib Ntsuas (MOG):Ib tug dial - hom gauge mounted rau lub conservator rau hauv av - theem visibility.

• Renewable Zog:Kauj ruam- nce transformers rau 2.X MW cua turbines (690V / 33kV).
• Petrochemical cog:Fais fab loj 690V lossis 3.3kV twj thiab compressors.
• Data Centers:Dedicated MV/LV units rau server halls xav tau N+1 redundancy.
