Xov Xwm Kev Lag Luam

Lub caij nyoog ntawd tab tom xaus. Niaj hnub no, cov transformers tab tom kawm tham. Nruab nrog cov sensors, txuas nrog huab, thiab siv los ntawm kev txawj ntse, ib tiam tshiab ntawm cov transformers ntse tuaj yeem tshaj tawm lawv txoj kev noj qab haus huv, kwv yees qhov ua tsis tiav, thiab ua kom zoo dua qhov kev ua haujlwm ntawm lub grid hauv lub sijhawm tiag tiag. Rau cov neeg ua haujlwm grid thiab cov kws tshaj lij kev yuav khoom, kev nkag siab txog cov cuab yeej ntse no yog qhov tseem ceeb.

Kev thawb kom txo cov pa roj carbon thoob ntiaj teb tau mus txog txhua lub ces kaum ntawm kev lag luam hluav taws xob - suav nrog lub transformer uas tsis muaj zog. Tau ntau xyoo, cov thev naus laus zis transformer tseem tsis hloov pauv: roj av rau kev rwb thaiv tsev, hlau ua los ntawm cov noob rau cov cores, thiab cov qib kev ua haujlwm uas tsuas yog txhim kho me ntsis xwb.

Thaum koj tau txiav txim siab txog cov lus qhia tshwj xeeb rau koj lub transformer, qhov kev cov nyom tom ntej yog kev txiav txim siab zoo rau kev lag luam. Koj yuav piv cov nqi ntawm cov neeg muag khoom sib txawv li cas? Koj yuav tsum nrhiav cov ntawv pov thawj twg thaum koj xa khoom tuaj? Koj yuav soj ntsuam li cas seb lub chaw tsim khoom puas tuaj yeem xa khoom raws sijhawm thiab ua tau raws li qhov xav tau zoo?

Lub transformer feem ntau hu ua lub zog ua haujlwm ntawm lub grid hluav taws xob. Nws tsis muaj cov khoom txav mus los, tsis tas yuav tsum tau saib xyuas ntau, thiab tuaj yeem ua haujlwm tau zoo rau ntau xyoo caum. Tab sis tom qab qhov yooj yim pom tseeb no yog cov txheej txheem tsim khoom uas tau hloov pauv ntau heev hauv lub xyoo pua dhau los.

Qhov ntawd yog thawj qhov kev xav uas ntau tus neeg muaj thaum lawv hnov ​​​​​​tias "transformer technology." Tom qab tag nrho, electromagnetic induction tau tshawb pom hauv xyoo 1831. Lub hauv paus ntawm lub transformer niaj hnub no tau teeb tsa los ntawm xyoo 1885. Zaj dab neeg tshiab twg uas lub cuab yeej 140 xyoo yuav muaj peev xwm qhia?

Txawm tias nws nyob hauv cov chaw hloov hluav taws xob lossis nyob rau ntawm cov ncej hluav taws xob, nws ua ib txoj haujlwm tseem ceeb - hloov cov theem hluav taws xob kom xa hluav taws xob mus deb - tsis muaj kev tshaj tawm lossis kev lees paub ntau. Nws yog qhov ua haujlwm zoo tshaj plaws: txhim khu kev qha, kwv yees tau, thiab tsis pom.

Hauv thaj chaw ntawm kev xa hluav taws xob siab, 220kV transformers ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev faib hluav taws xob zoo. qhov sib txawv ntawm kev rwb thaiv tsev tseem ceebNruab nrab ntawm cov xov hluav taws xob transformer yog ib qho ntawm cov qauv tsim tseem ceeb tshaj plaws, cuam tshuam ncaj qha rau kev ntseeg tau ntawm transformer, lub neej ntev, thiab kev ua tau zoo. Raws li cov thawj coj ua lag luam hauv kev siv tshuab transformer, peb lees paub tias kev tsim cov khoom rwb thaiv tsev zoo tshaj plaws yog qhov tseem ceeb rau kev tiv taus kev ntxhov siab hluav taws xob hnyav, suav nrog kev ua haujlwm tas mus li, xob laim, thiab kev hloov pauv surges.

Cov transformers nruab nrab-zaus (MFTs) yog cov khoom tseem ceeb hauv cov khoom siv hluav taws xob niaj hnub no, ua rau muaj kev hloov pauv hluav taws xob me me, ua haujlwm tau zoo thoob plaws cov ntawv thov xws li kev sib koom ua ke ntawm lub zog rov ua dua tshiab, cua sov hauv kev lag luam, thiab cov tshuab traction. Rau cov xwm txheej muaj zog siab uas xav tau 96kVA lub peev xwm, kev ua kom zoo dua cov transformers no hla kev ua haujlwm tau zoo, kev tswj hwm thermal, thiab kev sib raug zoo electromagnetic (EMC) yog qhov tseem ceeb kom ua tau raws li kev ua tau zoo thiab kev ntseeg tau. Tsab xov xwm no tshawb nrhiav txoj hauv kev ua kom zoo dua ntau qhov ntev rau 96kVA high-voltage MFTs, kev sib xyaw ua ke ntawm cov khoom siv tshiab, kev ua qauv siab heev, thiab kev tsim qauv zoo nkauj.

Hauv cov tshuab fais fab siab, txoj kev siv transformer neutral point grounding yog qhov tseem ceeb uas cuam tshuam rau kev nyab xeeb ntawm lub cev, kev ntseeg siab, thiab kev ruaj khov. Rau 110kV lub tshuab fais fab, kev xaiv txoj kev siv neutral point grounding ncaj qha cuam tshuam rau cov khoom siv rwb thaiv tsev, kev tiv thaiv overvoltage, kev teeb tsa kev tiv thaiv relay, thiab kev ntseeg siab ntawm lub zog. Hauv Suav teb, 110kV cov tshuab feem ntau siv a txoj kev grounding zoo ib nrab, qhov twg qee qhov chaw nruab nrab ntawm lub transformer raug grounded ncaj qha thaum lwm tus tseem tsis tau grounded, lub hom phiaj yog txwv cov hluav taws xob luv luv ib theem thaum tiv thaiv kev hem thawj overvoltage.

Lub tshuab hluav taws xob nruab nrab thiab siab, ib qho kev lag luam ib txwm muaj, tab tom ntsib kev saib xyuas thiab kev hloov pauv tsis tau muaj dua los ntawm kev hloov pauv hluav taws xob thoob ntiaj teb thiab kev siv tshuab xam zauv AI. Lub rooj hauv qab no muab cov lus qhia luv luv ntawm cov qauv tseem ceeb thiab cov yam ntxwv hauv cheeb tsam kom muab rau koj daim duab dav dav.
