Thaum koj tab tom yuav lossis tsim lub tshuab hluav taws xob hloov hluav taws xob-txawm nws yog rau daim phiaj siv hluav taws xob, lub chaw tsim hluav taws xob, lub hnub ci ua liaj ua teb, lossis cov nroj tsuag muaj kev lag luam- tau txais koj lub taub hau nyob ib ncig ntawm lub hwj chim transformer specification yog kiag li tsis yog -negotiable. Daim ntawv spec tsis yog ib pawg ntawm cov lej zoo nkauj xwb; Nws yog daim ntawv qhia uas qhia rau koj yog tias lub tshuab hloov pauv tuaj yeem ua haujlwm tau zoo, ua haujlwm tau zoo, thiab tsis muaj kev cuam tshuam ntawm kev thauj khoom.
Tau qhov spec txoj cai, thiab koj nyob nraum golden. Nws pab engineers pin down lub peev xwm, voltage theem, txias setups, tiv thaiv schemes, thiab kev ua tau zoo lub hom phiaj. Ntxiv rau, nws khaws txhua yam raws li loj - lub npe thoob ntiaj teb cov qauv xws li IEC thiab IEEE.
Ntawm no ntawm Jiangsu Yawei Transformer Co., Ltd., peb nyob thiab nqus cov khoom no. Peb nplawm li kev cai fais fab transformer kev daws teeb meem raws li txhua yam ntawm daim phiaj xwm txheej, cov khoom lag luam, cov tshuab hluav taws xob tauj dua tshiab, thiab cov phiaj xwm loj.
Dab tsi yog qhov Specification ntawm Fais Fab Transformer?
Xav txog nws raws li lub transformer tiav CV. Nws yog ib daim ntawv qhia uas sau tawm tag nrho cov hluav taws xob, khoom siv, thiab kev ua haujlwm yuav tsum tau-muaj.
Feem ntau, koj yuav pom:
Rated zog muaj peev xwm (hauv kVA lossis MVA)
Thawj thiab theem nrab voltage ntsuas
Ntau zaus
Phase configuration
Vector pawg
Impedance voltage
Coj mus rhaub hom hloov pauv (on-load lossis tawm-circuit)
Rwb thaiv tsev theem
Txoj kev txias
Poob qhov tseem ceeb thiab cov hom phiaj ua haujlwm
Luv -circuit withstand peev
Environmental tej yam kev mob (kub, qhov siab, thiab lwm yam)
Cov qauv siv tau
Cov khoom siv hluav taws xob, EPC cov neeg cog lus, thiab cov neeg tsim cov phiaj xwm cia siab rau cov specs zoo li vwm los sib piv cov qauv sib txawv thiab xoom rau ntawm cov khoom tsim nyog tshaj plaws.
Kev rhuav tshem cov ntsiab lus tseem ceeb
Cia peb taug kev los ntawm cov khoom tseem ceeb uas koj yuav pom ntawm daim ntawv qhia tshwj xeeb.
Qhov no yog qhov yooj yim- nws yog lub zog tshaj plaws uas pom tseeb tias lub tshuab hloov pauv tuaj yeem tso tawm tsis tu ncua raws li kev ua haujlwm ib txwm muaj.
| Hom Transformer | Hom Muaj Peev Xwm Ntau |
|---|---|
| Kev faib tawm Transformer | 25 kVA - 5000 kVA |
| Nruab nrab Fais Fab Transformer | 5 MVA – 100 MVA |
| Loj Fais Fab Transformer | 100 MVA – 1000 MVA+ |
Piv txwv li, 50 MVA fais fab transformer specification txhais tau tias nws muaj peev xwm lis 50 megavolt -amperes tsis- nres, hnub nyob rau hauv thiab hnub tawm.
Vim li cas qhov no tseem ceeb heev? Zoo, undersize nws, thiab koj tab tom saib overheating thiab ceev rwb thaiv tsev laus. Oversize nws, thiab koj tau nkim nyiaj ntawm tus nqi ua ntej thiab koj yuav tau them rau siab dua tsis muaj -load poob mus ib txhis. Nws yog ib qho kev sib npaug.
Qhov no yog ib tug ntawm cov hnyav hitters. Ib qho spec yuav nquag qhia qee yam xws li:
High Voltage (HV) / Tsawg Voltage (LV)
Xav tias:
110 kV / 10.5 kV
220 kV / 35 kV
35 kV / 0.4 kV
Qhov piv ntawd txiav txim siab qhov twg transformer haum nyob rau hauv lub dav zog network. Nov yog daim ntawv qhia ceev ceev:
| Qib voltage | Daim ntawv thov |
|---|---|
| 220 kV, 330 kV, 500 kV | Main kis kab sib chaws |
| 66 kV, 110 kV | Substations thiab cov phiaj xwm hauv cheeb tsam |
| 10kV, 20kV, 35kV | Local faib networks |
| 400V, 480V | Cov nroj tsuag thiab cov tsev lag luam |
Feem ntau specs yuav hais ib yam50 Hzlos yog60 Hz. Yooj yim txaus, txoj cai? Tab sis tsis txhob hnov qab nws - zaus messes nrog flux ceev, core tsim, poob, thiab kev khiav hauj lwm kub. Lub transformer ua rau 50Hz yuav tsis tas ua si zoo ntawm 60Hz yam tsis muaj kev kuaj xyuas ua tau zoo (thiab lwm yam).
Feem ntau koj yuav kam nrog ib qhopeb -phaselos yogib zaug -phasetransformers.
Cov spec kuj tseem yuav suav nrog pawg vector, uas qhia koj tias yuav ua li cas cov windings txuas nrog thiab theem hloov pauv. Nws yog me ntsis geeky, tab sis ntawm no yog saib ceev:
| Vector Group | Common Use Case |
|---|---|
| Dyn 11 | Distribution networks thiab industrial systems |
| YNd11 | High -voltage grid substations |
| YNd1 | Tej yaam num kis tau tus mob |
| Yy0 | Sib npaug peb -phase systems |
Qhov no yog ib qho loj rau kev ruaj ntseg system. Cov txiaj ntsig zoo sib txawv ntawm qhov loj:
| Transformer muaj peev xwm | Hom impedance |
|---|---|
| Cov me me | 4%–6% |
| Nruab nrab units | 6%–10% |
| Fais fab loj transformers | 10%–18% |
Cov impedance siab dua txhais tau tias qis dua - Circuit Court tam sim no (zoo rau kev ruaj ntseg), thaum qis impedance muab kev tswj hluav taws xob zoo rau koj (zoo rau kev txhawb nqa hnyav). Koj yeej ib co, koj poob ib co.
Qhov no ncaj qha dictates ntau npaum li cas load koj tuaj yeem thawb los ntawm chav tsev.
Cov txheej txheem muaj xws li:
ONAN (Oil Natural, Cua Natural):Cov khoom siv yooj yim- cov roj ntws thiab cua txias. Feem ntau yog rau me me transformers.
ONAF (Oil Natural, Cua Forced):Ntxiv cov kiv cua txias los txhim kho cov cua sov, cia koj nyem tawm ntau lub peev xwm.
OFAF (Oil Forced, Air Forced):Siv cov twj tso kua mis rau kev quab yuam cov roj thiab cov kiv cua rau kev quab yuam cua txias. Qhov no yog qhov hnyav - lub luag haujlwm teeb tsa rau cov chav loj.
Yog li, yog tias koj pom 50MVA ONAN / ONAF lub zog hloov pauv, nws txhais tau tias nws tau ntsuas rau 50MVA nrog lub ntuj txias, tab sis tuaj yeem ua haujlwm ntau dua thaum cov kiv cua ncaws.
Ib qho spec tag yuav sau ob qho tib si:
Tsis muaj -load Loss:Lub zog hlawv tsuas yog los ntawm energizing lub hauv paus (hysteresis thiab eddy tam sim no).
Load Loss:Thaum tshav kub kub generated los ntawm tam sim no ntws los ntawm windings (tooj liab poob thiab stray losses).
Nov yog ib qho piv txwv ntawm -world:
| Parameter | Tus nqi |
|---|---|
| Rated Peev Xwm | 63 MVA |
| Tsis muaj -load Loss | Tsawg dua los yog sib npaug li 30 kW |
| Load Loss | Tsawg dua los yog sib npaug li 250 kW |
| Kev ua tau zoo | Ntau dua lossis sib npaug li 99% |
Kev poob qis txhais tau tias pheej yig dua cov nqi khiav lag luam, cua sov tsawg dua, thiab lub neej ntev dua. Nws tsis yog - lub hlwb.
Qhov no nyob ntawm qhov system voltage thiab qhov twg koj tab tom txhim kho nws. Cov spec feem ntau yuav muab rau koj:
Lightning impulse withstand voltage
Fais fab zaus withstand voltage
Piv txwv li:
| Chav Kawm Voltage | Hom xob laim Impulse Level |
|---|---|
| 35kv ua | 1 70kv |
| 110kV ua | 4 80kv |
| 220 kV ua | 9 50kv |
Kev rwb thaiv tsev zoo yog koj qhov kev tiv thaiv zoo tshaj plaws tiv thaiv hluav taws xob surges, hloov overvoltages, thiab hluav taws xob kev ntxhov siab.
Kev tswj hluav taws xob yog qhov tseem ceeb, thiab feem ntau koj tau txais ob txoj hauv kev:
Tawm -Circuit Tap Changer (OCTC):Koj yuav tsum de-energize lub transformer los kho nws. Zoo rau daim phiaj ruaj khov.
Ntawm -Load Tap Changer (OLTC):Koj tuaj yeem tweak qhov voltage thaum nws nyob. Qhov no yog qhov mus- mus rau substations thiab kis systems.
Ib tug raug spec tej zaum yuav hais tias:± 8 × 1.25% kais ntau yam nrog tsis siv neeg voltage tswj.
Feem ntau cov specs yuav hais txog cov qauv thoob ntiaj teb:
| Txuj | Dab tsi Nws npog |
|---|---|
| IEC 60076: Ua | General fais fab transformer txheem |
| IEEE C57 Series | US - tsom xam cov qauv transformer |
| IEC 60296 (TSI) | Specification rau insulating roj |
| IEC 60529 (TSI) | Kev tiv thaiv kev tiv thaiv kev ntsuas (IP codes) |
Ua raws li cov no ua kom muaj kev nyab xeeb, kev ntseeg siab, thiab kev lees paub thoob ntiaj teb.
Piv txwv Specification Sheet (Rau siv)
Nov yog yam uas ib txwm yuav zoo li hauv kev xyaum:

Yuav Ua Li Cas Xaiv Qhov Zoo Spec rau Koj Qhov Project?
Ua ntej koj rub lub trigger, xav txog cov ntsiab lus no:
Qhov System Voltage:Muab ob npaug rau- txheeb xyuas nws sib npaug ntawm daim phiaj, lub tshuab hluav taws xob, lossis qhov hluav taws xob faib hluav taws xob uas koj ua haujlwm nrog.
Load Requirements:Ua lej raws li qhov xav tau tam sim no, cov phiaj xwm nthuav dav yav tom ntej, thiab qhov phem tshaj - cov ntaub ntawv siab tshaj.
Installation Ib puag ncig:Puas yog sab hauv lossis sab nraum zoov? Dab tsi yog qhov kub thiab txias, qhov siab, qhov av noo, thiab cov pa phem?
Zog Efficiency:Rau kev ua haujlwm ntev - lub sijhawm ua haujlwm, ua qhov tseem ceeb rau cov chav uas tsis muaj - thauj khoom thiab poob qis. Nws them tawm.
