2500kVA Transformer 1
ONAN vs ONAF Txias - Xauv lub zog 2500kVA
Niaj hnub nimno2500kVA faib transformersyog tsim nrog dual -theem cua txias:ONANrau base load thiabONAFrau qhov xav tau siab tshaj. Nkag siab txog qhov system hybrid no yog tus yuam sij rau kev nyab xeeb tshaj.
Dab tsi yog ONAN txias rau 2500kVA Chav?
ONAN (Oil Natural Cua Natural):Tsis muaj kiv cua. Cov roj kub transformer nce ib txwm mus rau hauv lub tshuab hluav taws xob, qhov twg huab cua ambient flows passively.
- Base peev: 2500kVA uatsis tu ncua.
- Qhov zoo tshaj plaws rau:Kev thauj khoom tsis tu ncua, qhov chaw nyob ntsiag to (piv txwv li, tsev kho mob lossis chaw nyob hauv tsev).
Dab tsi yog ONAF Txias rau 2500kVA Chav?
- ONAF (Oil Natural Air Forced):Tib roj ncig, tab siskiv cua quab yuam cuahla lub radiators, rho tawm cua sov sai dua.
- Overload peev (nrog cov kiv cua ntawm):Feem ntau3125kVA rau 3333kVA(25-33%).
- Qhov zoo tshaj plaws rau:Kev lag luam peaks, huab cua kub, lossis thaum muaj xwm txheej ceev.
Qhov siab tshaj plaws kev nyab xeeb tshaj - Cov Lus Qhia Tshwj Xeeb
| Txias hom | Nruam Muaj Peev Xwm | 2-Tsev Muaj Peev Xwm Ceev | 1-Hour Peak (nrog ua ntej thauj khoom<80%) |
|---|---|---|---|
| ONAN xwb | 2500kVA ua | 2750kVA (nrog roj kub ceeb toom) | 3000kVA (kev pheej hmoo ntawm kev laus sai) |
| ONAF koom nrog | 3125 kVA ua | 3300kVA ua | 3500kVA ua(tsuas yog ambient<30°C) |
Tseem ceeb:Txawm tias muaj ONAF, cua kub nce yuav tsum nyob qis dua lossis sib npaug li 65℃ib IEC 60076. GNEE embedsfiber ntau -optic winding kub sensorsnyob rau hauv txhua txhua 2500kVA chav tsev kom muaj kev nyab xeeb dynamic overload.
Copper vs Aluminium Windings - Qhov twg yog txoj cai rau koj 2500kVA Transformer?
Thaum qhia txog a2500kVA Transformer 1, cov khoom siv hluav taws xob cuam tshuam ncaj qha rau tus nqi, qhov loj me, thiab kev ua haujlwm zoo.
Copper Windings - Tus nqi siab dua, kev ua tau zoo dua
- conductivity:tooj liab yog ~ 40% ntau conductive tshaj txhuas.
- Qhov loj kom zoo dua:A 2500kVA tooj liab-kho hloov pauv tuaj yeem ua tau15-20% tsawg duahauv hneev taw thiab qhov hnyav.
- Lub zog:Zoo luv luv-circuit tiv taus - qhov tseem ceeb rau cov phiaj xwm kev lag luam nrog kev ua txhaum ntau zaus.
- Lifespan:Tooj liab tsis nkag los yog xoob ntau xyoo lawm.
Aluminium Windings - Tus nqi pib qis dua
- Tus nqi:Feem ntau30-35% pheej yig duatshaj tooj liab rau tib qhov ntsuas 2500kVA.
- Qhov tsis zoo:Loj dua -section xav tau – ua rau abulker transformer(ntxiv ~ 300-400 mm rau qhov ntev).
- Risk:Yuav tsum tau zoo meej bolted kev sib txuas; txwv tsis pub, thermal expansion tuaj yeem ua rau loosening.

Yam tsawg kawg nkaus Clearance Requirements for Safe Operation
- Airflow:Tsawg kawg800 hlintawm txhua sab rau ONAN txias;1000 hlintawm kiv cua rau ONAF.
- Roj ntim:Cia qhov chaw rau cov phab ntsa los yog lub tais ntim dej (feem ntau 110% ntawm cov roj ntim - ~ 3000 litres rau 2500kVA chav tsev).
- Qhov rooj qhib:Yog tias mus rau hauv "tsev", lub qhov rooj yuav tsum yog tsawg kawg2500 hli × 1800 hli dav.
- Qhov cua:Txawm tias nrog ONAF, chav tsev xav tau cov khoom noj khoom haus thiab cov kiv cua tawm - txwv tsis pub cua kub rov ua dua thiab txias tsis ua haujlwm.
Mineral Roj vs Ester Roj - Xaiv txoj cai Dielectric Fluid
Roj hom cuam tshuam rau hluav taws kev nyab xeeb, ib puag ncig kev pheej hmoo, thiab transformer lifespan. Rau ib2500kVA Transformer 1kev khiav hauj lwm hauv ONAN / ONAF loads, ntawm no yog koj phau ntawv qhia.
Mineral Roj - Qhov Kev Xaiv Tus Qauv
- Pros:Tus nqi qis tshaj, zoo heev dielectric zog, dav muaj.
- Cons:Qhov hluav taws kub qis (~ 160 degree) - muaj kev pheej hmoo siab nyob hauv tsev lossis ze ntawm cov khoom siv hluav taws xob.
- Qhov zoo tshaj plaws rau:Substations sab nraum zoov, tej thaj chaw deb, los yog qhov twg pob nyiaj siv yog thawj.
Ntuj Ester (FR3) lossis Synthetic Ester
- Pros: Fire point >300℃(K-cov kua hauv chav kawm), biodegradable, txuas daim ntawv rwb thaiv tsev lub neej los ntawm 5-8 xyoo.
- Cons:2-3x kim dua li cov roj ntxhia, viscous ntau dua (kev ua haujlwm qeeb qeeb - yuav tsum muaj cov hluav taws xob loj me me).
- Qhov zoo tshaj plaws rau:Kev teeb tsa sab hauv tsev, khw malls, tsev kho mob, thaj chaw rhiab heev.
