Hauv hluav taws xob hluav taws xob, hloov pauv yog qhov tseem ceeb rau kev hloov kho hluav taws xob, ua kom muaj kev nyab xeeb thiab muaj hluav taws xob muaj kev nyab xeeb thiab muaj txiaj ntsig zoo. Ib qho tseem ceeb ntawm cov khoom tseem ceeb uas pab tswj cov hluav taws xob tsis muaj kev cuam tshuam lub lag luam yog qhovTsis muaj {- LOAD TAIS HLOOV (NLTC)Cov. Cov cuab yeej no feem ntau siv nyob rau hauvRoj -}} Cov hloov pauv hloov, qhov twg cov roj ua raws li ob qho tib si insulator thiab txias nruab nrab.
Hauv cov blog no, peb yuav dhia mus rau hauv dab tsi NLTC yog, nws ua haujlwm li cas, thiab vim li cas nws yog qhov tseem ceeb rau kev ua tau zoo ntawm cov hluav taws xob cuam tshuam.
Dab tsi yog NLTC?
A Tsis muaj {- LOAD TAIS HLOOV (NLTC)Yog ib qho cuab yeej nyob hauv tus transformer uas tso cai rau kev hloov kho ntawm ntau qib los ntawm xaiv cov kais dej sib txawv ntawm cov hloov cua. Tus yam ntxwv tseem ceeb ntawm NLTC yog tias nws tsuas yog ua haujlwm thaum transformer yogtsis nyob rau hauv load, lub ntsiab lus nws yuav tsum yog -} energized ua ntej hloov cov kais dej.
Tsis zoo li tusNyob rau - Pead Take Changer (OLTC), uas tuaj yeem ua haujlwm thaum lub transformer yog nyob rau hauv thauj, NLTC xav tau tus hloov pauv hloov ua ntej tus kais hloov tshwm sim. Qhov no txhais tau tias cov kev cai voltage yuav tshwm sim thaum lub transformer tsis tau muab cov kev hloov pauv uas xav tau yam tsis muaj kev hloov pauv yooj yim yam tsis muaj kev thauj khoom.
Nltc ua haujlwm li cas?
Ib qho NLTC tso cai rau tus neeg teb xov tooj hloov cov kais dej ntawm tus hloov pauv cua, hloov kho lub voltage tso zis. Tus kais hloov pauv tau txuas nrog ob peb tus kais ntawm ntau cov ntsiab lus ntawm transformer winding. Los ntawm xaiv cov kais sib txawv, tus hloov pauv tau tso tawm txawv voltage.
Txij li thaum tus kais hloov pauv hauv ib qho NLTC tshwm sim tsuas yog thaum Transformer yog de-}}}}}} pa taws lossis ntsuas lub tshuab kom muaj kev ua haujlwm no. Cov txheej txheem ntawm kev xaiv cov taps koom nrog cov kauj ruam hauv qab no:
Fais fab kev cais: Ua ntej ua cov kev hloov pauv, tus hloov pauv yuav tsum tau coj offline los xyuas kom meej tias tsis muaj tam sim no ntws.
Coj mus rhaub xaiv: Tom qab cais lub zog, nltc xaiv cov kais tshiab ntawm lub transformer's winding. Qhov no feem ntau ua tiav los ntawm kev hloov pauv lub tshuab hloov pauv, yog phau ntawv lossis lub cev muaj zog.
Kev hloov kho hloov kho: Tus kais tshiab kho tus voltage tawm ntawm lub transformer. Lub NLTC muab ntau txoj kev xaiv voltage uas tuaj yeem xaiv raws cov khoom siv thauj khoom lossis cov xwm txheej.
Vim li cas NLTCS tseem ceeb hauv cov tshuab hloov roj?
Cov kev cai voltage nyob rau hauv cov xwm txheej ruaj khov: NLTCS feem ntau yog siv nyob rau hauv cov xwm txheej uas voltage kev cai yog qhov tsim nyog tab sis tus thauj khoom yog ruaj khov. Lawv yog cov txiaj ntsig tshwj xeeb rau kev hloov kho thaum lub load yog tsawg lossis thaum transformer yog tawm ntawm kev pabcuam.
Kev ntseeg tau thiab kev nyab xeeb: Vim tias NLTC ua haujlwm tsuas yog thaum Transformer yog offline, tsis muaj kev pheej hmoo ntawm arcing lossis zog surges thaum lub sij hawm hloov. Qhov no ua rau kev ua haujlwm muaj kev nyab xeeb dua thiab muaj ntau heev piv tau piv rau OLTCS, uas ua haujlwm nyob rau hauv load.
Ntev - Term efficiency: Lub luag haujlwm tseem ceeb ntawm NLTC yog kom ntseeg tau tias ntau cov qib txuas nyob rau hauv ntau yam uas yuav tsum muaj rau lub network. Qhov no ua kom ntev ntev -}} kev ua tau zoo ntawm cov kab phiaj hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj zog hloov qee zaum, thiab kev hloov kho tsis tu ncua.
Tus nqi -} Siv tau ua tau zoo rau qee cov kev siv: Rau qee qhov kev thov hloov pauv hloov uas nquag voltage kev tswj hwm tsis tsim nyog, siv NLTC muaj tus nqi ntau dua li OLTCS. Nltcs yog yooj yim dua thiab muaj tsawg dua txav chaw, uas tuaj yeem ua rau cov nqi kho tus nqi qis dua.
Cov ntsiab lus tseem ceeb ntawm NLTC system
Coj mus rhaub Selctor Hloov: Tus kais SELECTOR hloov yog siv los xaiv cov kais dej uas xav tau rau ntawm transformer winding. Nws feem ntau yuav tsum tau ib qho kev tswj hwm sab nraud, xws li lub cev muaj zog, rau cov haujlwm ua haujlwm.
Mechanism: Vim tias NLTC ua haujlwm thaum lub transformer tsis nyob hauv qab thauj, nws suav nrog kev sib cais kom ntseeg tau tias lub hwj chim tau hloov ua ntej hloov cov kais dej.
Switchgear thiab mechanism: Lub chaw sib dhos ua ke ntawm cov kais pauv kev ua haujlwm, ua kom muaj kev nyab xeeb thiab precise tso tawm ntawm cov kais dej.
Roj comprartment: Hauv cov roj -}}} rack cov transformers, roj ua haujlwm ua ib qho nruab nrab insulating uas kuj yuav pab ua kom sov. Cov roj sib xyaw ua ke uas cov kais {{2} Hloov cov tshuab nyob twj ywm txias thiab zoo {{} insulated.
Kev cov nyom thiab txij nkawm ntawm NLTCS
Txawm hais tias NLTCs kuj yooj yim thiab txhim khu kev qha, lawv tseem tuaj nrog qee cov kev cov nyom:
Muaj tsawg dua: Vim tias NLTCS tsuas tuaj yeem hloov cov kais dej thaum lub transformer yog offline, lawv tsis tuaj yeem teb rau kev hloov pauv tsis sib haum xeeb hauv kev thauj khoom. This limits their use in situations where continuous voltage regulation is needed, such as in high-demand grid systems.
Kev Lag Luam Kev Ua Haujlwm: Ntau cov tshuab nltc yuav tsum tau ua haujlwm hauv kev ua haujlwm, uas tuaj yeem qhia txog kev hloov pauv ntawm kev kho qhov hluav taws xob thaum xav tau. Xav paub ntau ntxiv cov khoom siv tsis tau zoo tuaj yeem txhim kho lub luag haujlwm.
Kho: Sijhawm dhau sijhawm, Cheebtsam lwm yam xws li cov kais Selector hloov yuav hnav tawm. Kev tshuaj xyuas ib txwm yog tsim nyog los xyuas kom meej tias lub NLTC ua haujlwm tau zoo thiab tias cov roj muaj kev sib kis uas tuaj yeem cuam tshuam.
Cov Lus Qhia Txij Nkawm rau NLTCS:
Xyuas kom meej tias tus transformer yog cais kom zoo ua ntej ua cov kais hloov pauv.
Txheeb xyuas cov roj ua tau zoo tsis tu ncua kom ntseeg tau tias rwb thaiv tsev kom zoo thiab txias ntawm lub system.
Soj ntsuam cov khoom siv tshuab, suav nrog cov kais tshuaj xaiv, rau hnav.
Kev sim ua ntu zus rau kev ua haujlwm ntawm NLTC system los xyuas kom muaj kev ua haujlwm zoo.
