Daim ntawv qhia tswv yim rau 10 MVA Transformers: Specs, Qhov hnyav, Qhov ntau thiab tsawg, Nqe & Yuav Nrhiav Dab Tsi (2026 Tsab)
Yog tias koj tab tom cuam tshuam nrog nruab nrab -cov tshuab hluav taws xob loj-xav cov chaw nres tsheb, cov chaw tsim khoom loj, hnub ci lossis cua ua liaj ua teb, cov chaw khaws ntaub ntawv, lossis tsuas yog daim phiaj siv hluav taws xob xwb-a10 MVA transformer(uas yog 10,000 kVA lossis 10 megavolt-amperes) yog qhov zoo nkauj npaum li mus- mus rau cov neeg ua haujlwm. Nws txuas qhov sib txawv ntawm cov hluav taws xob ntau dua li 33 kV, 66 kV, lossis txawm tias 69 kV mus rau theem nruab nrab xws li 11 kV, 13.8 kV, lossis 4.16 kV. Cov khoom no muaj nyob txhua qhov chaw hauv kev teeb tsa lub zog loj.
Hauv phau ntawv qhia no, kuv yuav taug kev koj los ntawm cov khoom tseem ceeb: cov qauv tshwj xeeb, hnyav npaum li cas thiab loj npaum li cas, cov nqi ntxhib rau xyoo 2026, qhov sib txawv ntawm substation / fais fab hom thiab ncoo -mounted sawv daws yuav, ntxiv rau qee qhov tiag -lub ntiaj teb cov lus qhia ntawm xaiv qhov yog.
1. Yog li, 10 MVA Transformer yog dab tsi? Thiab Qhov twg Cov Neeg Siv Lawv?
Feem ntau, koj tab tom saib cov roj -immersed, peb-theem theem. Standard txias yogONAN(roj ntuj, huab cua ntuj -tsuas yog cia cua sov nce thiab cua ntws hla nws). Yog tias koj xav tau ntau dua lub taub hau taub hau, qee qhov tuaj nrogONAF(cov kiv cua ncaws hauv kom yuam cua ntau dua).
Common voltage setups koj yuav pom:
33/11 kV - nrov heev nyob rau hauv Asia, qhov chaw ntawm cov teb chaws Europe, thiab ntau lub chaw siv hluav taws xob
66/11 kV lossis 69/13.8 kV - ntau rau cov chaw lag luam lossis cov khoom siv txuas ntxiv
34.5/4.16 kV los yog 24.9/0.48 kV - ntau dua nyob rau hauv North America, tshwj xeeb tshaj yog ncoo -mounted versions
Cov kev cai xws li 132/11 kV lossis 35/10 kV yog tias qhov project xav tau nws
Lawv tshwm sim nyob rau hauv txhua hom ntawm qhov chaw:
Main lossis backup transformers nyob rau hauv substations
Powering loj factories, mines, ports, hnyav kev lag luam
Kauj ruam- nce / kauj ruam- nqes ntawm hnub ci PV ua liaj ua teb lossis chaw nres tsheb cua
Pub cov ntaub ntawv chaw zov me nyuam thiab cov lag luam loj lossis cov tsev nyob
2. Hom Specs rau 10 MVA Transformer
Ntawm no yog qhov koj tau txais ntawm tus qauv 10 MVA 33/11 kV roj-immersed unit (ONAN txias, tooj liab windings, Dyn11 kev sib txuas pab pawg):
Rated zog: 10 MVA / 10,000 kVA
Zaus: Feem ntau 50 Hz, tab sis muaj 60 Hz versions
Cua txias: ONAN txheem; ONAF xaiv tau (muab koj kwv yees li 20-30% ntxiv tshaj)
Impedance: 6-12%, feem ntau zaum ntawm 7-8%
Tsis muaj-load poob: Ib yam li 8-12 kW
Load poob (tag nrho load): Nyob ib ncig ntawm 40-70 kW
Kub nce: Roj 60 degree, windings 65℃yog tus qauv zoo nkauj
Rwb thaiv tsev / BIL: HV sab feem ntau LI 170 kV / AC 70 kV; LV sab LI 75 kV / AC 28 kV
Kais changer: Off-load yog yooj yim; ntawm -load (OLTC, hais ± 10 × 1.5%) yog tias koj xav tau kev hloov pauv nyob voltage
Efficiency: Feem ntau 98.5-99% ntawm tag nrho cov load
Ua raws li cov qauv zoo li IEC 60076, IEEE / ANSI C57, thiab lwm yam.
Tau kawg, txhua yam hloov pauv nyob ntawm tus tsim, koj cheeb tsam, lossis cov khoom ntxiv xws li qis- poob amorphous cores, biodegradable FR3 kua, los yog harmonic{2}}resistant K-factor designs.
3. Lawv hnyav npaum li cas? Thiab Lawv Siv Qhov Chaw Ntau Npaum Li Cas?
Qhov hnyav thiab hneev taw nyob ntawm seb nws puas yog lub chaw nres tsheb qub / fais fab lossis lub ncoo -mounted ib qho, ntxiv rau qib voltage, txias, tooj liab vs aluminium windings, thiab roj ntim.
Rau substation / fais fab mov transformers(xws li 33/11 kV lossis 66/11 kV, ONAN):
Tag nrho qhov hnyav: Feem ntau 14,000-28,000 kg (15-28 tons)
Roj ib leeg: 4,000-7,500 kg
Rough qhov ntev (L × W × H): 4,000-4,800 mm × 2,900–4,000 mm × 3,000–4,000 mm
Cov piv txwv tiag tiag: Qee cov qauv 33/11 kV tuaj nyob ib ncig ntawm 18,500 kg tag nrho (nrog ~ 4,800 kg roj). Cov hluav taws xob siab dua lossis cov hluav taws xob loj dua tuaj yeem thawb nws mus rau 23,000-28,000 kg.
Rau cov ntaub qhwv -mounted versions(piv txwv li, 24.9 kV lossis 12.47 kV thawj):
Tag nrho qhov hnyav: Feem ntau 14,000-16,000 kg
Roj: Kwv yees li 2,850-3,000 litres
Dimensions: Qhov siab ntawm 2,900 hli, qhov tob 2,800 hli, dav 2,700 hli
Pad-mounts yog ntau compact thiab me ntsis sib zog ua tsaug rau cov ua tau - nyob rau hauv enclosure thiab feem ntau qis rwb thaiv tsev theem. Ntxiv OLTC, kiv cua, tus neeg saib xyuas, lossis tswb thiab xuav, thiab qhov hnyav tuaj yeem dhia 20-50%. Ib txwm muab ob npaug rau- tshawb xyuas cov chaw tsim khoom cov ntaub ntawv-tsis txhob kwv yees ntawm kev thauj mus los!
4. Yuav ua li cas 10 MVA Transformers Nqi hauv 2026?
Tus nqi viav vias raws li qhov hluav taws xob, cua txias, kais hloov hom, tooj liab vs aluminium, qhov twg nws tau tsim (Tuam Tshoj nyiam pheej yig dua li Europe / US), cov ntawv pov thawj (UL, IEC, IEEE), thiab cov khoom xws li tooj liab cov nqi lag luam.
Rough ballpark ranges (USD, ex-works, 2026):
Basic 33/11 kV substation type (ONAN, off-load kais): $30,000–$80,000
Nrog OLTC lossis zoo dua nta: $ 80,000– $ 150,000
Pad-mounted (hais 24.9/0.48 kV): $100,000–$160,000
Ntau dua qhov hluav taws xob (69 kV +) lossis kev cai / qis- poob / eco- kua: $ 120,000– $ 220,000 lossis ntau dua
Dab tsi txav lub koob:
Copper windings raug nqi ntau dua tab sis khiav txias dua / ua haujlwm zoo; aluminium txuag ua ntej tab sis tej zaum yuav hnyav dua los yog tsawg dua
Asian factories feem ntau yeej European / US ntawm tus nqi
Kev txiav txim ntau lossis kev sib tw loj pab
Ntxiv xws li cov bushings tshwj xeeb, kev saib xyuas, kev tiv thaiv surge, cov xim zoo nkauj
Rau cov lus hais zoo, tham nrog cov neeg xws li Daelim, ABB, Siemens, lossis cov chaw muag khoom hauv zos. Cov nqi tuaj yeem hloov nrawm nrog cov ntaub ntawv.
5. Lub tswv yim xaiv qhov zoo
Ntsia koj qhov voltage piv thiab daim phiaj xav tau ua ntej (impedance teeb meem rau qib ua txhaum)
Txias: Lo nrog ONAN rau kev siv ib txwm; mus ONAF yog tias koj xav tias hnyav siab
Kais hloov pauv: OLTC tsim nyog nws yog tias qhov hluav taws xob hloov pauv ntau
Mus rau qis- qauv poob yog tias tus nqi hluav taws xob siab- them rov qab rau lub sijhawm
Substation (sab nraum zoov qhib) vs ncoo-mounted (cuam tshuam, nroog- phooj ywg)
Xyuas kom nws ua tau raws li IEC / IEEE cov qauv; nug hom ntawv xeem
Tsis txhob hnov qab logistics-15-30 tons txhais tau tias koj xav tau cov phiaj xwm hnyav hnyav
Wrapping Up
Lub 10 MVA transformer ntaus qhov sib npaug zoo: muaj peev xwm ntau yam tsis muaj qhov loj lossis vwm kim. Txawm hais tias nws tuav lub chaw nres tsheb hluav taws xob los yog pab sib koom ua ke rov ua dua tshiab, tau txais cov specs txoj cai txhais tau tias nws yuav ua tau zoo rau 30+ xyoo.
Yog tias koj tab tom yuav khoom lossis sib piv tam sim no, xa kuv cov lus qhia ntxiv -zoo li koj qhov hluav taws xob thawj / theem nrab, txawm tias koj xav tau lub ncoo-mounted lossis substation style, lossis koj qhov chaw nyob -thiab kuv tuaj yeem sim ua kom qis dua ntxiv. Zoo siab pab!
