Lub Transformer Substation yog dab tsi?

Ib qho chaw nres tsheb me melub tshuab hluav taws xobyog ib hom transformer tshwj xeeb uas tsim los hloov cov theem voltage hauv ib qho chaw hloov hluav taws xob. Nws pab txhawb kev xa hluav taws xob los ntawm cov kab xa hluav taws xob siab mus rau cov theem voltage qis dua uas tsim nyog rau kev faib rau cov neeg siv khoom.

Cov Transformers rau Chaw Nres Tsheb Siv Hluav Taws Xob:

Cov hloov pauv hluav taws xob rau chaw nres tsheb fais fabfeem ntau yog siv los ntawm Kev Faib Fais Fab cov tuam txhab. Lawv tau txais hluav taws xob muaj zog siab thiab txo nws mus rau qhov hluav taws xob qis dua, uas tom qab ntawd tuaj yeem faib rau cov tsev thiab cov lag luam. Cov transformers no tuaj yeem tso tawm ob qho tib si ib theem thiab peb theem AC tam sim no, thiab lawv tseem ceeb hauv cov tes hauj lwm faib hluav taws xob hauv nroog thiab nyob deb nroog. Kev teeb tsa cov transformers siv hluav taws xob feem ntau ua raws li cov qauv thoob ntiaj teb xws li IEC thiab IEEE, ua kom ntseeg tau tias muaj kev ntseeg siab thiab kev nyab xeeb.

Cov Transformers Chaw Nres Tsheb Tus Kheej:

Cov transformers ntawm chaw hloov hluav taws xob rau tus kheej pab cov neeg siv kawg, xws li tsev kawm ntawv, tsev kho mob, thiab cov khw noj mov. Cov transformers no feem ntau ua haujlwm ntawm qhov nruab nrab thiab qis voltage, ua kom muaj kev nyab xeeb thiab siv hluav taws xob tau zoo raws li qhov xav tau tshwj xeeb ntawm lub tsev. Lawv tseem ceeb heev rau cov cheeb tsam uas xav tau cov chaw muab hluav taws xob tshwj xeeb, pab txo qhov hloov pauv voltage thiab txhim kho qhov zoo ntawm lub zog.

Transformer hauv av Substation:

Cov transformers hauv av hauv av yog tsim tshwj xeeb rau kev teeb tsa qhov chaw uas muaj chaw tsawg. Cov transformers no tau teeb tsa hauv av kom txo lawv qhov cuam tshuam rau qhov muag thiab tiv thaiv lawv los ntawm cov yam ntxwv ib puag ncig. Cov ntaub ntawv tshwj xeeb thiab cov roj feem ntau siv los ua kom tau raws li cov qauv kev nyab xeeb thiab zoo, txo qhov kev pheej hmoo ntawm cov teeb meem kev ua haujlwm hauv qhov chaw kaw. Cov transformers no ua kom ntseeg tau tias txawm tias nyob hauv nroog uas muaj neeg coob coob, kev faib hluav taws xob tseem ua haujlwm tau zoo thiab tsis pom kev.

Yuav ua li cas ib tugTransformer Chaw Nres TshebUa haujlwm?

Kev ua haujlwm ntawm lub substationlub tshuab hluav taws xobyog raws li kev siv hluav taws xob electromagnetic induction. Thaum alternating current (AC) ntws los ntawm lub winding thawj, nws tsim ib lub magnetic field. Lub magnetic field no ces induces voltage nyob rau hauv lub winding thib ob los ntawm electromagnetic induction.

Nov yog kev piav qhia ntxiv txog cov txheej txheem:

1. Qhov Hluav Taws Xob Nkag: Lub transformer tau txais hluav taws xob muaj zog siab los ntawm lub grid fais fab los ntawm sab muaj zog siab. Qhov hluav taws xob no feem ntau yog txij li 11 kV mus txog 440 kV, nyob ntawm hom transformer ntawm chaw hloov hluav taws xob.
2. Cov Txheej Txheem Induction: Cov tam sim no hauv lub winding thawj tsim ib lub magnetic teb, uas tom qab ntawd induces voltage hauv lub winding thib ob. Qhov piv ntawm tus naj npawb ntawm cov tig hauv lub thawj thiab thib ob windings txiav txim siab seb lub voltage yog stepped up lossis stepped down.
3. Kev Hloov Pauv Hluav Taws Xob: Raws li tus qauv tsim ntawm lub transformer, qhov hluav taws xob uas tau tsim tuaj yeem nce (step-up transformer) lossis txo (step-down transformer) mus rau qib uas xav tau. Qhov no yog qhov tseem ceeb rau kev sib npaug ntawm qhov hluav taws xob thoob plaws hauv lub network fais fab thiab xyuas kom meej tias kev xa khoom mus rau cov neeg siv kawg muaj kev nyab xeeb.
4. Lub Tshuab Txias: Hauv Roj-Immersed Transformers, cov roj nyob ib puag ncig pab txias cov kauj thiab lub plawv. Thaum lub transformer ua haujlwm, cua sov raug tsim, thiab cov roj nqus cov cua sov no, uas pab tswj kom muaj qhov kub thiab txias zoo tshaj plaws.
5. Lub Hwj Chim Tawm: Lub hwj chim hloov pauv ces raug xa tawm los ntawm sab uas muaj hluav taws xob tsawg, npaj txhij rau kev faib rau cov neeg siv khoom. Lub hwj chim no feem ntau yog txij li 0.6 kV txog 35 kV, tsim nyog rau kev siv hauv tsev thiab kev lag luam.

Cov Hom Dab TsiCov Transformers SubstationPuas Muaj?

Cov transformers substation tuaj yeem raug faib ua pawg raws li ntau yam qauv, suav nrog qib voltage, lub hom phiaj, thiab txoj kev teeb tsa.

-Cov Transformers Substation High Voltage: Cov transformers no ua haujlwm ntawm cov theem voltage txij li 11 kV txog 69 kV thiab tau tsim los tswj cov hluav taws xob high voltage.

-EHV (Extra High Voltage) Substations: Cov transformers EHV ua haujlwm nrog cov voltages txij li 132 kV txog 440 kV, ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob mus deb.

-Cov Transformers Kauj Ruam Nce thiab Kauj Ruam Nce: Cov transformers no nce lossis txo cov theem voltage raws li qhov xav tau, kom ntseeg tau tias kev xa hluav taws xob zoo thoob plaws hauv lub network.

-Kev rho tawm Transformers: Cov no yog siv los cais cov ntu sib txawv ntawm lub zog fais fab, kom muaj kev nyab xeeb thaum lub sijhawm txij nkawm thiab kev ua haujlwm.

-Cov Transformers Zaus Hloov Pauv: Tsis tshua muaj rau kev siv hauv tsev, cov transformers no kho qhov zaus ntawm cov khoom siv hluav taws xob, feem ntau yog siv rau hauv kev siv hauv kev lag luam.

Lub Transformer Substation hnyav npaum li cas?

Qhov hnyav ntawm lub tshuab hloov hluav taws xob hauv chaw hloov hluav taws xob tuaj yeem sib txawv ntau nyob ntawm nws tus qauv tsim, lub peev xwm, thiab cov ntaub ntawv siv. Feem ntau, cov tshuab hloov hluav taws xob loj dua tuaj yeem hnyav ntau tons. Piv txwv li, lub tshuab hloov hluav taws xob uas muaj peev xwm ntawm 5000 kVA tuaj yeem hnyav li ntawm 27,000 kg (kwv yees li 60,000 lbs), thaum cov tshuab hloov hluav taws xob loj dua tuaj yeem tshaj 50,000 kg (kwv yees li 110,000 lbs).

Cov Yam Tseem Ceeb Uas Cuam Tshuam Rau Qhov Hnyav:

-Kev Ntsuas Qhov Muaj Peev Xwm: Cov transformers muaj peev xwm siab dua yuav hnyav dua vim muaj cov kauj vuam ntxiv thiab cov cores loj dua.

- Cov Khoom Siv: Hom roj siv rau kev txias (mineral, zaub, lossis siliceous) kuj ua rau qhov hnyav.

-Cov Qauv Tsim: Cov qauv tsim tshwj xeeb yuav ntxiv qhov hnyav vim muaj cov yam ntxwv kev nyab xeeb ntxiv lossis cov ntaub ntawv tsim kho tshwj xeeb.

Qhov Sib Txawv Ntawm Transformer Thiab Substation

Txawm hais tias ob qho tib si transformers thiab substations yog qhov tseem ceeb rau cov kab ke faib hluav taws xob, lawv ua haujlwm sib txawv:

-Cov khoom siv hloov hluav taws xob yog cov khoom siv uas hloov hluav taws xob los ntawm ib theem mus rau lwm qib siv kev siv hluav taws xob electromagnetic induction. Lawv tuaj yeem pom muaj nyob rau hauv ntau yam kev siv, los ntawm kev teeb tsa hauv tsev mus rau cov kab ke hauv kev lag luam.

-Cov chaw hloov hluav taws xob (substations), ntawm qhov tod tes, yog cov chaw uas muaj cov transformers, circuit breakers, thiab lwm yam khoom siv los tswj thiab tswj kev ntws ntawm hluav taws xob hauv lub grid fais fab. Lawv ua haujlwm ua cov chaw sib txuas tseem ceeb uas cov hluav taws xob muaj zog siab raug hloov mus rau cov hluav taws xob qis dua rau kev faib tawm.

Hauv kev xaus lus, kev nkag siab txog kev ua haujlwm ntawm cov hloov pauv hloov pauv hauv chaw hloov pauv yog qhov tseem ceeb rau txhua tus neeg uas koom nrog kev tsim hluav taws xob lossis kev faib hluav taws xob. Cov hloov pauv no yog qhov tseem ceeb hauv kev ua kom muaj hluav taws xob xa mus rau cov neeg siv khoom kom muaj kev nyab xeeb thiab ua tau zoo thaum tswj hwm kev ua haujlwm ntawm lub zog hluav taws xob. Raws li qhov kev thov rau lub zog ruaj khov txuas ntxiv mus, lub luag haujlwm ntawm cov hloov pauv hloov pauv hauv chaw hloov pauv yuav tseem ceeb zuj zus, qhia txog qhov xav tau kev nce qib hauv kev siv tshuab thiab kev coj ua hauv kev tsim kho.
