Step Up Transformers rau Cua Zog: Yam Koj Yuav Tsum Paub Txog
Thaum tib neeg tham txog cua zog, lub turbines tau txais txhua lub yeeb koob. Thiab tseeb, lawv saib txias. Tab sis ncaj ncees? Lub cua ua liaj ua teb yuav tsis mus deb heev yam tsis muaj ib pawg tom qab- lub - scenes iav ua qhov hnyav nqa. Nyob ze ntawm daim ntawv teev npe yog kauj ruam nce transformer rau cua zog tiam.
Tsis yog ib qho glamorous khoom siv. Tab sis ntawm no yog qhov - yog tias tsis muaj qhov hloov pauv no txhawm rau txhawm rau qhov hluav taws xob, lub zog los ntawm cua turbine yuav tawm tsam mus rau txhua qhov chaw zoo. Xav tias nws yog qhov sib txuas ntsiag to ntawm "ua kom muaj zog" thiab ua tau "xa lub zog."
Nyem rau cov lus qhia ntxiv txog Yawei Hoobkas.
Rau cov kws tshaj lij, EPC cov neeg cog lus, cov khoom siv hluav taws xob, thiab cov neeg yuav khoom, tau txais kev xav tias yuav ua li cas cov tshuab hloov pauv no tuaj yeem txuag tau ib tuj mob taub hau hauv txoj kev - thiab pab koj xaiv lub iav zoo yam tsis muaj qhov thib ob -xav koj tus kheej.
Yog li, Dab tsi Ua Ib Kauj Ruam Transformer rau Cua Zog Ua Tau?
Lub tshuab hluav taws xob cua turbine tsis tawm hluav taws xob tawm ntawm qhov hluav taws xob ntawm daim phiaj tuaj yeem nqos tau xwb. Qhov ntawd yog qhov twgtransformercov kauj ruam hauv (pun intended).
Nws txoj hauj lwm yog qhov yooj yim: coj lub tshuab hluav taws xob tsis tshua muaj hluav taws xob thiab crank nws mus rau qib siab dua rau cov khoom sib sau los yog daim phiaj siv hluav taws xob.
Vim li cas thab? High voltage=qis tam sim no. Tsawg tam sim no=tsawg zog poob raws txoj kev. Rau cov cua ua liaj ua teb loj, cov nyiaj khaws cia ntxiv - lub sijhawm loj.
Hom Transformer Peb tham txog dab tsi?
Tsis yog txhua tus transformers yog tsim sib npaug. Nov yog yam koj pom nyob rau ntawd:
| Hom Transformer | Qhov twg siv |
|---|---|
| Roj -Yam | Feem ntau onshore cua turbines |
| Pad-Mounted | Zaum ntawm lub hauv paus turbine |
| Compact substation | Sau & faib systems |
| Qhuav -Hom | Offshore lossis sab hauv tsev (qhov teeb meem kev nyab xeeb hluav taws) |
| Fais fab Transformer | Main substations & kab sib txuas cov ntsiab lus |
Rau feem ntau onshore tej yaam num,roj- puv transformersyog cov laus txhim khu kev qha. Lawv tau nyob ib puag ncig mus ib txhis, lawv tawv, thiab lawv tuav cov cua sov zoo li champ.
Offshore? Qhov ntawd yog ib tug tsiaj nyaum txawv. Qhov chaw nruj, cov cai hluav taws xob nruj dua, thiab ib puag ncig tsis zoo. Yog li koj yuav xav tau txoj hauv kev sib txawv.
Lub Transformer zais nyob qhov twg hauv Cua Turbine?
Zoo lus nug. Cov lus teb? "Nws nyob."
Qee cov tuam txhab lag luam stick lub transformer txoj cai nyob rau hauv lub nacelle, ze rau lub tshuab hluav taws xob. Shorter cables, zoo dua efficiency - yog lub tswv yim.
Lwm tus muab tso rau hauv qab ntawm tus pej thuam. Ntau tus neeg ua haujlwm zoo li qhov no zoo dua - kev saib xyuas yog txoj hauv kev yooj yim dua, thiab koj cov thev naus laus zis tsis tas yuav nce ib lab ko taw xwb txhawm rau txheeb xyuas cov khoom.
Thiab qee zaum, tshwj xeeb tshaj yog ntawm cov haujlwm loj dua, lub tshuab hloov pauv zaum sab nraud hauv lub ncoo -mounted lub thawv ntawm ib sab ntawm lub cav.
Txhua qhov kev teeb tsa muaj nws qhov zoo thiab qhov tsis zoo. Cov neeg tsim qauv feem ntau tsuas yog xaiv qhov ua kom nkag siab rau qhov chaw thiab ntau npaum li cas lawv xav muab tso rau hauv kev saib xyuas.
Dab tsi yog qhov Voltage Ua Lub Cua Turbine tso tawm?
Tsis yog txhua lub turbines zoo ib yam. Nws nyob ntawm qhov loj thiab lub tshuab hluav taws xob tsim.
Ntawm no yog ib daim ntawv qhia ntxhib:
| Turbine Loj | Hom Generator Voltage |
|---|---|
| 1-2 MW | 690V |
| 2-5 MW | 690V-1.14kV 1 |
| 5-10 MW | 3.3kV – 6.6kV |
| Loj Offshore | Mus txog 11 kV |
Thiab raws li turbines tau loj dua, cov tuam txhab lag luam maj mam txav mus rau ntau dua lub tshuab hluav taws xob hluav taws xob - kev ua haujlwm zoo dua, qis dua tam sim no.
Thaum lub hwj chim ntawd tawm ntawm lub tshuab hluav taws xob, lub tshuab hluav taws xob tau ncaws tawm thiab txhawb nws dua rau kev sib kis.
Hom Voltage Jumps
| Lub tshuab hluav taws xob | Daim phiaj / Collection Voltage |
|---|---|
| 690V | 33kv ua |
| 690V | 35kv ua |
| 3.3kv ua | 66kv ua |
| 11kv ua | 1 32kv |
Cov lej tiag sib txawv raws lub tebchaws thiab cov cai siv hluav taws xob, tab sis cov no zoo nkauj heev nyob rau hauv tiag tiag -cov dej num hauv ntiaj teb.
Peb tham txog Transformer loj npaum li cas?
Qhov ntsuas qhov ntsuas ntawm transformer feem ntau yog sib npaug ntawm cov turbine cov zis.
| Turbine Rating | Hom Transformer Rating |
|---|---|
| 1.5 MW TSI | 1.6–2 MVA |
| 2 MW ib | 2.5 MAV |
| 3 MW | 3.15–4 MAV |
| 5 MW ib | 5–6.3 MVA |
| 8 MW ib | 8–10 MVA |
Feem ntau cov nqi hluav taws xob- ntsuas cua ua liaj ua teb hnub no siv cov tshuab hloov pauv hauv 2.5 MVA txog 10 MVA ntau yam - muab lossis nqa.
Tau kawg, txhua qhov project yog qhov txawv me ntsis. Cov xwm txheej ntawm lub xaib, cov kev xav tau ntawm kab sib chaws, thiab cov phiaj xwm yav tom ntej txhua tus ua lub luag haujlwm.
Piv txwv li: Dab tsi Transformer rau 5 MW Turbine?
Qhov no tshwm sim txhua lub sijhawm hauv kev npaj qhov project.
Tseeb, 5 MW turbine tuaj yeem ua ke nrog 5 MVA transformer. Tab sis ntau tus tsim tawm mus me ntsis loj dua. Lub peev xwm ntxiv ntawd muab rau koj lub ncoo rau kev ua haujlwm txawv txawv thiab pab nrog kev xav tau lub zog reactive.
Nov yog yam uas tib neeg yeej xaiv:
| Turbine tso zis | Common Transformer Rating |
|---|---|
| 5 MW ib | 5 MVA |
| 5 MW ib | 5.5 MAV |
| 5 MW ib | 6.3 MAV |
Ua siab ncaj? 6.3 MVA yog qhov chaw qab zib. Tsis overkill, tab sis muab koj chav ua pa. Thiab chav ua pa tsis yog qhov phem.
Ib tug raug spec tej zaum yuav zoo li:
Rated zog: 6.3 MVA
Thawj qhov hluav taws xob: 690V
Qhov nruab nrab voltage: 33kV
Zaus: 50Hz lossis 60Hz
Txoj kev txias: ONAN
Vector Group: Dyn11
Dab tsi yog Cua Transformer Spec Zoo li
Thaum koj tab tom muab tso ua ke ib qho RFQ lossis technical spec, ntawm no yog cov khoom koj yuav xav sau:
| Parameter | Tus nqi |
|---|---|
| Rated Peev Xwm | 2.5–10 MVA |
| Thawj Voltage | 690V, 1.1kV, 3.3kV, TSI |
| Secondary Voltage | 11kV, 22kV, 33kV, 35kV, 66kV |
| Ntau zaus | 50Hz / 60Hz |
| Hom cua txias | ONAN los yog ONAF |
| Vector Group | Dyn11, YNd11 |
| Kev teeb tsa | Sab nraum zoov |
| Coj mus rhaub Changer | Off-Circuit lossis On-Load |
Thiab feem ntau cov neeg ua liaj ua teb cua kuj xav tau kev saib xyuas thiab tiv thaiv iav zoo li:
Buchholz relays
Winding kub saib xyuas
Surge arresters
Kev saib xyuas online
SCADA kev koom ua ke
Cov khoom me me no yuav zoo li me me, tab sis ntseeg kuv - lawv pab tiv thaiv kev poob qis thiab ua rau kev saib xyuas tsis zoo.
Dab tsi yog Cov Qauv Koj Yuav Tsum Tau Saib Xyuas?
Cua transformers yuav tsum tau ua raws li cov qauv. Cov loj yog:
IEC Cov Qauv
IEC 60076 - Fais fab Transformers
IEC 60076 -11 - Hom Qhuav
IEC 60296 - Cov roj rwb thaiv tsev
IEC 60529 - Kev tiv thaiv (IP ntsuas)
IEEE Standards
IEEE C57 Series - Cov khoom tsim dav dav
IEEE C57.12.00 - Cov kev cai dav dav
IEEE C57.12.90 – Testing
Thiab tsis txhob hnov qab - cov khoom siv hluav taws xob feem ntau muaj lawv tus kheej specs. Qee zaum cov teeb meem tsuas yog ntau npaum li cov qauv thoob ntiaj teb.
Yuav Ua Li Cas Sib Piv Cov Khoom Siv Tsis Tau Los Ntawm Koj Lub Siab
Nqe tseem ceeb. Tau kawg nws ua. Tab sis txhua tus neeg uas nyob ib puag ncig paub qhov pheej yig tshaj transformer tsis yog qhov zoo tshaj plaws deal nyob rau hauv ntev.
Saib ze ntawm:
Tsis muaj -load poob
Load poob
Luv - lub zog hluav taws xob
Kev tiv thaiv corrosion
Hoobkas kuaj muaj peev xwm
Cov sij hawm xa tuaj
Kev pab txhawb nqa
Cua zog kev paub
Ib qho kev hloov pauv zoo tuaj yeem siv sijhawm 25-30 xyoo, qee zaum ntev dua. Tshaj li qhov kev ua neej nyob, kev ua tau zoo thiab kev ntseeg tau tuav ob peb txhiab nyiaj tawm ntawm tus nqi tag nrho txhua lub sijhawm.
Wrapping It Up
A nce transformer rau cua zog tiamtsis yog qhov flashiest ntawm cua ua liaj ua teb. Tab sis nws yog ib qho tseem ceeb tshaj plaws. Nws ua rau kev sib kis tau zoo, pab cov kab sib chaws ua si zoo, thiab cuam tshuam rau lub sijhawm ntev - kev ua tiav ntawm tag nrho qhov project ncaj qha.
Txawm hais tias koj tab tom speccing iav rau lub vev xaib tshiab lossis sib piv cov neeg xa khoom rau kev tsim yav tom ntej, siv sijhawm los nkag siab txog kev ntaus nqi, qhov ntsuas hluav taws xob, specs, thiab cov qauv. Nws yuav pab koj xaiv qhov ntse dua. Thiab nyob rau hauv loj zog tej yaam num? Cov kev xaiv ntse no them rau ntau xyoo lawm.
