Dab tsi yog Sab hauv Fais Fab Transformer?
Nyob rau hauv lub hwj chim transformer, lub ntsiab active qhov chaw yog cov hlau nplaum, windings, rwb thaiv tsev thiab hluav taws xob sib txuas ntawm lawv. Cov tub ntxhais qhia kev sib txawv sib nqus flux, thaum lub windings hloov hluav taws xob los ntawm electromagnetic induction. Nyob rau hauv ib tug roj-immersed transformer, lub active sib dhos no yog nyob rau hauv lub tank nrog insulating kua, bushings thiab ib tug txias txias. Kais-hloov thiab saib xyuas cov cuab yeej kuj yuav haum, nyob ntawm tus qauv tsim.
Tsis yog txhua txhua transformer muaj tib yam kev tsim kho. Cov tshuab ziab khaub ncaws qhuav siv cov rwb thaiv tsev sib txawv thiab cov txheej txheem kaw los ntawm cov roj-immersed units, thiab cov cuab yeej xaiv tau txawv ntawm qhov ntsuas thiab lub luag haujlwm. Kev nkag siab txog cov khoom siv pab tus neeg yuav khoom nyeem cov lus qhia hluav taws xob, tab sis nws tsis tsim kev teeb tsa ntawm ib chav tsev tshwj xeeb. Rau cov kev faib khoom sib koom ua ke, JSGK muab Cov Txheej Txheem Hloov Pauv raws li kev siv nrog rau nws cov substation thiab switchgear khoom tsev neeg, tsis yog pov thawj ntawm standalone transformer manufacturing.
Magnetic Core: Ib Txoj Kev rau Hloov Flux
Ib tug transformer tus tub ntxhais muab ib tug tsawg-reluctance magnetic txoj kev txuas cov windings. Nws yog feem ntau ua los ntawm insulated laminations ntawm cov khoom sib nqus es tsis yog ib qho khoom hlau thaiv. Laminations pab txo cov kev poob tam sim no uas yuav tshwm sim los ntawm kev hloov cov hlau nplaum sib nqus. Qhov tshwj xeeb geometry, cov khoom siv thiab kev tsim kho yog nyob ntawm tus qauv tsim transformer.
Cov tub ntxhais muaj cov ceg tawv thiab cov yokes ua rau lub voj voog sib nqus. Nws lub luag haujlwm yog txhawb nqa electromagnetic coupling; nws tsis yog ib qho hluav taws xob conductor txuas lub hauv paus Circuit Court ncaj qha mus rau theem nrab Circuit Court. Qhov kev sib txawv no yog qhov tseem ceeb vim hais tias ib qho zoo tib yam ob-winding transformer hloov lub zog magnetically thaum tswj cov rwb thaiv tsev sib cais los ntawm nws tus qauv tsim.
Thawj thiab Secondary Windings: Qhov twg Voltage Hloov
Windings muaj insulated conductors teem nyob ib ncig ntawm lub magnetic core. Thaum ib qho alternating voltage yog siv rau cov input winding, hloov flux induces voltage nyob rau hauv lwm winding. Kev sib raug zoo ntawm kev hloov pauv yog qhov tseem ceeb rau kev hloov pauv hluav taws xob, txawm hais tias kev ua haujlwm tseem ceeb kuj nyob ntawm kev poob, kev tswj hwm thiab kev tsim hluav taws xob tag nrho.
Hauv ntau cov qauv tsim cov high-voltage thiab low-voltage windings yog lub cev txheej txheem los tswj cov rwb thaiv tsev clearances, coupling, tshem tawm cua sov thiab mechanical zog. Kev sib txuas ua ke coj cov winding terminals mus rau kev sib txuas sab hauv, bushings lossis kais-hloov cov cuab yeej raws li qhov tsim nyog. Ib qho yooj yim 'tooj liab coils hauv ib lub thawv' cov lus piav qhia tsis nco txog cov rwb thaiv tsev, kev txhawb nqa thiab kev sib txuas cov qauv tsim nyog rau kev sib koom ua ke kom ua nws txoj haujlwm.
Winding conductor khoom, txheej txheej, kev npaj thiab luv luv-circuit withstand cov yam ntxwv yuav tsum tau txheeb xyuas los ntawm cov chaw tsim khoom tsim cov ntaub ntawv tsim. Cov lus piav qhia ntawm no tsis sawv cev rau kev tsim kho sab hauv rau ib qho JSGK-branded transformer.
Internal rwb thaiv tsev cais txawv hluav taws xob muaj peev xwm
Transformer rwb thaiv tsev cais lem nyob rau hauv ib tug winding, nyob ib sab windings thiab conductive qhov chaw ntawm txawv hluav taws xob muaj peev xwm. Nws kuj txhawb kev tshem tawm ntawm cov neeg ua haujlwm nquag, cov tub ntxhais kawm thiab lwm yam qauv. Nyob ntawm tus qauv tsim, rwb thaiv tsev yuav siv tau cov khoom siv, thaiv, spacers, insulating kua thiab tswj clearances.
Cov txheej txheem rwb thaiv tsev yuav tsum tau nkag siab ua ke nrog qhov kub thiab txias thiab kev ua haujlwm. Rau ib qho kev tsim roj-immersed, kua ua haujlwm hluav taws xob rwb thaiv tsev thiab hluav taws xob hloov hluav taws xob, nrog rau cov khoom siv insulating. Ib chav tsev qhuav siv qhov sib txawv ntawm cov khoom rwb thaiv tsev thiab huab cua lossis lwm yam kev tshaj tawm tshwj xeeb. Cov no yog cov tsev neeg kev tsim kho dav dav, tsis yog kev hloov pauv sab hauv.
Lub Tank thiab Insulating Liquid hauv Roj-Immersed Designs
Nyob rau hauv ib tug pa roj-immersed hwj chim transformer, ib tug hlau tank encloses lub core-thiab-winding los ua ke thiab insulating kua. Lub tank muab kev tiv thaiv thiab kev tiv thaiv txhua yam, thiab nws cov kev tsim kho yog kev sib xyaw nrog thermal expansion, siab, sealing thiab txias yuav tsum tau ua.
Cov kua ua ob qho tib si rwb thaiv tsev thiab tshav kub-hloov luag hauj lwm. Nws nqa cov cua sov tawm ntawm qhov chaw mus rau qhov chaw txias los yog txuas nrog lub tshuab txias txias. Hom kua thiab nws compatibility nrog cov ntaub ntawv thiab kev khiav hauj lwm tej yam kev mob yuav tsum tau paub tseeb hais tias rau qhov tshwj xeeb tsim. Lub tshuab ziab khaub ncaws qhuav tsis muaj tib lub roj puv lub ntsiab tank kev npaj.
Bushings: Kev sib txuas hluav taws xob los ntawm kev kaw
Lub bushing tso cai rau tus neeg xyuas pib lub zog kom dhau los ntawm qhov chaw hloov pauv hauv av thaum tuav cov hluav taws xob tsim nyog. Nyob rau hauv ib chav tsev uas muaj roj, bushings muab insulated interfaces ntawm sab hauv windings los yog leads thiab sab nraud fais fab system. Lawv qhov ntsuas thiab kev tsim kho txawv ntawm qhov hluav taws xob thiab lub luag haujlwm tam sim no.
Qee cov qauv tsim siv ntau hom bushings los yog lub davhlau ya nyob twg kev npaj, yog li cov neeg yuav khoom yuav tsum tsis txhob xav tias txhua tus transformer qhia tib yam khoom siv sab nrauv porcelain. Qhov tseeb kev sib txuas sab nraud thiab kev tshem tawm yuav tsum muaj nyob rau ntawm cov khoom siv kos duab thiab qhov project specification.
Coj mus rhaub Changers Kho qhov zoo Winding lem
Tus kais hloov pauv xaiv ntawm cov ntsiab lus sib txuas winding los kho qhov hloov pauv hloov pauv tau zoo thiab yog li nws qhov kev sib raug zoo voltage. Qee qhov kev tsim qauv siv de-energized kais hloov, uas yuav tsum tau teev cov kev pabcuam tsis raug. Lwm tus muaj qhov hloov pauv ntawm lub tshuab hluav taws xob tsim los ua haujlwm thaum lub tshuab hloov pauv tseem muaj zog raws li qhov xwm txheej tau hais tseg.
Cov no yog cov txheej txheem sib txawv thiab cov haujlwm ua haujlwm. Lub xub ntiag, qhov chaw thiab hom kev hloov pauv hloov pauv yuav tsum tau txheeb xyuas qhov tseeb ntawm qhov hloov pauv. Tsis yog txhua lub tshuab hloov pauv siv tib lub tshuab hloov pauv, thiab kev paub ntawm cov khoom sab hauv tsis yog kev qhia ua haujlwm lossis kev pabcuam rau lawv.
Txias Cheebtsam tshem tawm cov cua sov los ntawm lub Active Assembly
Core thiab winding poob ua kom sov. Lub tshuab hluav taws xob hloov pauv cov cua txias hloov pauv uas cua sov tam sim ntawd ua haujlwm nyob rau hauv nws cov kev txwv thermal tsim. Cov roj-immersed chav tsev yuav siv cov phab ntsa tank, radiators, kiv cua, twj tso kua mis los yog cais cov khoom cua txias, nyob ntawm seb qhov ntsuas thiab txias txoj kev. Tsis yog txhua chav muaj xws li kiv cua lossis twj tso kua mis.
Hauv cov tshuab ziab khaub ncaws qhuav, kev hloov pauv cua sov nyob ntawm qhov tshwj xeeb rwb thaiv tsev thiab cua txias kev npaj, qee zaum pab los ntawm cov kiv cua. Roj-immersed thiab qhuav-hom tshuab yog li tsis tuaj yeem piv tau yooj yim los ntawm kev suav cov khoom siv cua txias sab nraud. Lub luag haujlwm txias txias thiab ib puag ncig kev ua haujlwm tswj kev xaiv.
Conservators, Breathers thiab Protection Devices are Design-Dependent
Qee cov kua-filled transformers siv lub tank conservator kom haum rau cov kev hloov hauv cov kua ntim. Nyob ntawm qhov kev npaj, lub tshuab ua pa tuaj yeem pab tswj xyuas qhov xwm txheej ntawm huab cua nkag mus rau hauv lub conservator system. Lwm qhov kev teeb tsa siv kaw los yog hermetically kaw kev tsim kho thiab tsis muaj qhov kev tswj xyuas tib yam.
Kev tiv thaiv thiab kev saib xyuas cov khoom siv tuaj yeem suav nrog ntsuas qhov kub thiab txias, cov cuab yeej ntsig txog siab, ntsuas roj-qib thiab kev tiv thaiv roj rau ntawm cov qauv tsim uas cov cuab yeej tsim nyog. Lawv lub neej tsis yog universal. Cov neeg yuav khoom yuav tsum tau nyeem cov npe khoom siv tau pom zoo thiab schematic es tsis xav tias phau ntawv txiav tawm yog qhov sawv cev tag nrho ntawm txhua qhov hloov pauv.
Dry-Type vs. Roj-Immersed Transformers: Dab tsi yog txawv hauv?
Cov tub ntxhais sib nqus thiab cov windings yog qhov tseem ceeb rau ob tsev neeg, tab sis kev rwb thaiv tsev, thaiv thiab cua txias sib txawv. Qhov sib piv hauv qab no piav qhia txog cov ntsiab lus ib txwm tsis yog cov qauv tshwj xeeb.
| Feature | Qhuav hom tsim | Roj-immersed tsim |
|---|---|---|
| Sib nqus core | Tam sim no | Tam sim no |
| Cua txias | Tam sim no, insulated raws li tsim | Tam sim no, nyob rau hauv cov khoom siv / kua rwb thaiv tsev |
