Qhov sib txawv ntawm OLTC thiab NLTC ntawm transformer
# Qhov txawv ntawm OLTC thiab NLTC ntawm Transformers
OLTC thiab NLTC yog ob hom kev hloov pauv. OLTC stands rau On -load kais changer, uas tuaj yeem hloov qhov voltage thaum lub transformer khiav. NLTC txhais tau tias Tsis yog-load kais hloov pauv, nws tuaj yeem hloov qhov hluav taws xob thaum lub tshuab hloov pauv tsis ua haujlwm.
Nyob rau hauv lub ntiaj teb no ntawm lub hwj chim transformers, nws yog ib qho tseem ceeb kom paub txog cov sib txawv yog hais tias koj ua hauj lwm nyob rau hauv cov hluav taws xob kev lag luam. Ob hom transformers yog OLTC (Ntawm -Load Tap Changer) thiab NLTC (Tsis yog-Load Tap Changer). Hom transformer no muaj lawv tus kheej siv thiab ua kom haum rau qee yam haujlwm. Hauv tsab xov xwm no, peb yuav tham txog qhov sib txawv tseem ceeb ntawm OLTC thiab NLTC transformers, lawv cov txiaj ntsig, thiab thaum twg yuav siv lawv.
Ua ntej nkag mus rau hauv cov ntsiab lus hais txog OLTC thiab NLTC transformer, qhia rau peb ua ntej paub dab tsi yog transformers thiab nws lub luag hauj lwm nyob rau hauv hluav taws xob system. Transformer yog ib qho khoom siv hluav taws xob uas hloov hluav taws xob hluav taws xob los ntawm ib lub voj voog mus rau lwm qhov los ntawm electromagnetic induction. Lawv yog siv rau kev nce (qib nce) lossis txo qis (qib nqis) qhov voltage ntawm lub zog hluav taws xob, yog li lawv tsim nyog rau kev faib khoom thiab xa hluav taws xob.
OLTC txhais tau tias On Load Tap Changer. Raws li lub npe txhais tau hais tias, OLTC transformers tuaj yeem hloov lawv qhov chaw kais thaum lub transformer tseem nyob rau hauv load. Qhov kev muaj peev xwm no ua rau muaj qhov hloov pauv tsis tau txiav tawm lub zog hluav taws xob, yog li nws muaj txiaj ntsig zoo rau kev ua kom lub zog ruaj khov hauv daim phiaj hluav taws xob.
1. Kev ua haujlwm tsis tu ncua:OLTC transformers tuaj yeem hloov qhov voltage yam tsis tau kaw lub transformer, qhov no yog qhov tseem ceeb rau cov tshuab uas xav tau kev siv hluav taws xob tas li.
2. Kev tswj hluav taws xob:Nws pab ua kom qhov voltage ntawm ib theem tsis tu ncua txawm tias lub load hloov. Qhov no tau lees tias cov khoom siv hluav taws xob yuav ua haujlwm zoo thiab nyab xeeb.
3.Flexibility:OLTC transformers tuaj yeem hloov mus rau qhov sib txawv ntawm cov khoom thauj thiab muab kev yooj yim hauv kev tuav lub zog xa khoom.
OLTC transformer feem ntau yog siv rau kev sib kis thiab kev faib tawm uas yuav tsum tau muaj kev tswj xyuas hluav taws xob. Kuj pom muaj nyob rau hauv cov ntawv thov kev lag luam uas xav tau lub zog zoo kom tswj tau tas li.
NLTC txhais tau tias Tsis yog -Load Tap Changer. OLTC transformers tsis xav tau lub transformer de-energized hloov lub kais chaw, whereas NLTC transformers ua. Nws txhais tau hais tias qhov kev hloov pauv voltage tsuas yog ua tau thaum lub transformer tsis muab lub zog.
1. Simplicity:NLTC transformers muaj cov qauv tsim yooj yim dua li OLTC transformers, yog li lawv yuav tsum tau saib xyuas thiab nqi tsawg.
2. Nqi -zoo:Lawv feem ntau pheej yig dua OLTC transformers, yog li lawv yog ib qho kev xaiv zoo rau qhov chaw uas koj tsis tas yuav hloov cov kais dej ntau zaus.
3. Kev ntseeg tau:Tsawg qhov txav mus los txhais tau tias NLTC transformers tuaj yeem txhim khu kev ntseeg ntau dua nyob rau qee qhov xwm txheej.
NLTC transformers yog qhov tsim nyog rau cov xwm txheej uas qhov kev hloov pauv tsis tshua muaj, xws li qee qhov chaw muaj kev lag luam lossis cov chaw xa hluav taws xob nyob deb nroog uas muaj qhov sib txawv me ntsis hauv kev thauj khoom.
· OLTC:Nws tuaj yeem hloov cov kais dej thaum nws ua haujlwm, yog li nws muaj kev ua haujlwm zoo dua qub thiab ib txwm muab hluav taws xob.
· NLTC:Kais hloov yuav tsum tau ua nrog lub hwj chim tawm, uas txwv qhov yooj ntawm kev tswj voltage.
· OLTC:Ntau qhov nyuaj vim nws xav tau cov txheej txheem rau ntawm -load kais - hloov pauv uas tuaj yeem ua rau nws kim dua.
· NLTC:Kev tsim qauv yooj yim, feem ntau tus nqi qis dua, tab sis tsis nyob ntawm - kev hloov kho.
· OLTC:Yuav tsum tau saib xyuas ntau dua vim tias muaj cov khoom txav mus rau kev hloov kais.
· NLTC:Feem ntau muaj kev cia siab ntau dua nrog kev saib xyuas tsawg dua vim tias muaj tsawg dua qhov txav.
Txawm yuav xaiv OLTC los yog NLTC transformer yog txiav txim los ntawm qhov yuav tsum tau ntawm lub hwj chim system. OLTC transformer yog qhov tsim nyog tshaj plaws thaum ua kom qhov hluav taws xob tas li ntawm cov khoom sib txawv. Hauv qhov sib piv, yog tias lub kaw lus ua haujlwm tsis tu ncua thiab hloov hluav taws xob me me, NLTC transformer yuav zoo dua vim nws pheej yig dua thiab txhim khu kev qha.
Txhawm rau nkag siab qhov sib txawv ntawm OLTC thiab NLTC transformers yog qhov tsim nyog rau kev txiav txim siab kom raug ntawm kev faib hluav taws xob thiab kev tswj hwm. Txhua yam ntawm transformer muaj nws tus kheej zoo thiab yog haum rau ntau yam kev siv. Xav txog kev ua haujlwm yooj yim, tus nqi, thiab kev saib xyuas, koj tuaj yeem xaiv hom transformer tsim nyog uas ua tau raws li koj cov kev xav tau tshwj xeeb.
Los xaus, OLTC transformers muaj dynamic voltage tswj peev xwm uas ua rau lawv haum rau txawv load tej yam kev mob; NLTC transformers yog qhov yooj yim thiab pheej yig rau kev thauj khoom tas li. Txawm hais tias nws nyob hauv tsev, ua haujlwm, lossis xa hluav taws xob mus ntev, xaiv qhov zoo ntawm transformer tseem ceeb kom paub tseeb tias peb tau txais peb lub zog qhov peb xav tau.
