Heavy-Lub luag haujlwm muaj daim phiaj kab
Cov1250 kVA Roj Immersed Transformeryog engineered los ua lub hauv paus zog hub rau hnyav industrial chaw thiab loj coj mus muag cheeb tsam. Nrog rau qhov ntsuas qis -voltage tam sim no tawm ntawm kwv yees li18 00 amp, chav tsev no muab lub peev xwm loj uas yuav tsum tau tsav tsheb loj loj tswj chaw (MCCs) thiab cov tshuab hnyav.
Ua raws li cov kauj ruam tseem ceeb -down link, qhov no11kv transformer uazoo converts nruab nrab voltage daim phiaj fais fab (11,000V) mus rau ib tug ruaj khov 400V los yog 415V siv theem. Nws yog tsim los nrog kev txhim kho rwb thaiv tsev sib koom ua ke kom tiv thaiv kab sib chaws hloov pauv, ua kom muaj kev nyab xeeb ntawm cov khoom siv qis qis qis -voltage.
Txias Scalability: ONAN rau ONAF
Ib qho tshwj xeeb ntawm 1250 kVA qib yog qhov hloov tau ntawm lub tshuab cua txias. Thaum tus txheej txheem chav ua haujlwm rauONAN (Oil Natural Air Ntuj), lub tank tsim feem ntau suav nrog cov kev cai rau cov kiv cua txias.
- Overload muaj peev xwm:Los ntawm kev kho dua tshiab rauONAF (Oil Natural Cua Forced)cua txias (ntxiv cov kiv cua sab nraud rau lub tshuab hluav taws xob), lub peev xwm ntawm chav tsev no tuaj yeem txhawb nqa tau zoo15% mus rau 20%. Qhov no tso cai rau cov neeg saib xyuas chaw tswj xyuas qhov kev loj hlob ntawm qhov kev npaj txhij txog yam tsis tau hloov pauv tag nrho transformer tam sim ntawd.
- Radiator Configuration:Tsis zoo li cov chav me me uas siv cov phab ntsa ruaj khov, 1250 kVA qauv feem ntau siv.detachable vaj huam sib luag radiators. Qhov no muaj kev ua kom sov zoo dua thiab ua kom yooj yim txij nkawm, vim tias cov tsev txhab nyiaj radiator tuaj yeem raug cais lossis hloov yog puas.
Cov kiv cua txias tau nruab rau ntawm 1250 kVA 11kV transformer radiators
rau ONAF overload muaj peev xwm.
High-Voltage Engineering
Kev ntseeg ntawm MV sab yog qhov tseem ceeb. Raws li tus thawj tswj hwm11kv transformer ua, qhov siab -voltage windings yog qhov txhab siv ntau- txheej rwb thaiv tsev ntawv kom ua tau raws li cov txheej txheem Basic Impulse Level (BIL) (feem ntau yog 75kV lossis 95kV ncov). Qhov no ua kom lub tsev nyob ruaj khov tiv thaiv hluav taws xob los yog hloov cov impulses uas muaj nyob rau hauv 11kV nyiaj siv ua haujlwm faib khoom siv.

Installation & Connection Context
Muab cov zis tam sim no thiab cov chav kawm voltage, cov kev xav tau ntawm kev teeb tsa yog qhov tshwj xeeb:
- HV Termination:Sab 11kV tuaj yeem haum nrog lub thawv cable haum rau XLPE cables lossis qhib bushings rau kev sib txuas ntawm cov nyiaj siv ua haujlwm, nyob ntawm qhov chaw qauv.
- LV Termination:Vim yog qhov nyuaj ntawm kev txiav tawm ntau cov cables hnyav rau 1800A, LV sab feem ntau haum nrogloj busbar xibteslos yog tshwj xeeb flange rauBusbar Trunking System (BBT)kev sib txuas.
- Foundation:Chav tsev no yuav tsum muaj lub pob zeb muaj zog ntxiv uas muaj peev xwm txhawb nqa tag nrho qhov hnyav tshaj3,5t ua.
1250 kVA roj immersed transformer ntsia rau ntawm lub pob zeb plinth
nyob rau hauv ib tug industrial substation.
