Transformer yog cov khoom siv hluav taws xob tseem ceeb tshaj plaws hauv lub zog hluav taws xob, thiab nws feem ntau ua haujlwm ntev. Txhawm rau ua kom lub transformer muaj kev nyab xeeb thiab kev lag luam, txhim kho kev ntseeg tau ntawm kev ua haujlwm, feem ntau cia ob lossis ntau tshaj ob lub transformers ua haujlwm ua ke.
Parallel lag luam ntawm transformer yog ib tug nyuaj xam cov txheej txheem, nws essence yog los txhim kho tag nrho cov peev xwm ntawm transformer. Tab sis thaum lub transformer khiav nyob rau hauv parallel, lub thib ob sab tsis yog tsuas yog txuas nrog ib daim. Ua ntej lub sijhawm ua haujlwm ntawm lub transformer, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xyuas thiab paub meej tias daim ntawv teev npe ntawm lub transformer saib seb nws puas ua tau raws li cov kev cai ntawm kev ua haujlwm sib luag. Cov xwm txheej rau kev ua haujlwm sib luag ntawm transformers yog:
1. Cov kab hluav taws xob yog tib yam.
2, qhov hloov pauv yog tib yam, qhov sib txawv tsis ntau tshaj ± 0.5%.
3, luv Circuit Court voltage yog tib yam, qhov sib txawv tsis ntau tshaj ± 10%.
4. Lub peev xwm piv ntawm ob transformers tsis ntau tshaj 3: 1.
Kev ua haujlwm sib luag ntawm transformer yog kev ua haujlwm sib luag ntawm" fais fab mov", thiab nws txoj kev nyuaj yog ntau dua li kev ua haujlwm sib luag ntawm kev thauj khoom. Yog hais tias lub transformer tsis ua raws li cov kev cai nyob rau hauv parallel thiab yuam thaum uas tig mus ua ke, yuav muaj ib tug zoo" ncig" nruab nrab ntawm ob lub transformers, tsis yog tsuas yog pov tseg hluav taws xob hluav taws xob, tab sis kuj ua rau muaj kev nyab xeeb zoo heev.
Tsis tas li ntawd, kev ua haujlwm ntawm lub tshuab hluav taws xob sib txuas, vim tias lawv cov impedance yog sib npaug, tag nrho impedance yuav raug txo, qhov luv-circuit tam sim no ntawm lub kaw lus yuav zoo heev, xaiv cov khoom siv hluav taws xob hloov hluav taws xob tau muab tso rau ntau dua, qhov teeb meem no yuav tsum tau xav txog. hauv kev tsim.
Yog hais tias tus thawj system tsis nyob rau hauv parallel, xws li feem ntau ntawm cov lag luam ntawm hluav taws xob fais fab system yog ib tug ib tug busbar seem kev twb kev txuas, feem ntau, los ntawm cov cuab yeej tswj theem, hloov ob mus rau hauv kab nyob rau hauv cov xwm txheej ntawm H2 thiab H3 yog kaw, ntu hloov H1 tsis pub hloov, feem ntau nyob rau hauv lub lag luam ntawm lub hwj chim mov ntawm lub tuam txhab hluav taws xob fais fab mov yuav qhia tau hais tias pom zoo raws li nyob rau hauv daim ntawv cog lus. Txawm li cas los xij, los ntawm kev pom zoo, segmented hloov H1 tuaj yeem raug kaw thaum ob qho tib si ntawm ob qho khoom siv H2 thiab H3 raug kaw. Qhov kev ua haujlwm no paub tias tsis muaj kev cuam tshuam ntawm kev hloov pauv ntawm kev khiav haujlwm, tab sis lub sijhawm rau kev kaw ib txhij ntawm peb lub keyboards yuav tsum tau luv kom ntau li ntau tau. Tom qab lees paub qhov ua tiav tiav ntawm H1, hloov H2 lossis H3 sai li sai tau.
Tau kawg, txhawm rau ua kom lub tshuab hloov pauv muaj kev nyab xeeb thiab kev lag luam, txhim kho kev ntseeg tau ntawm cov khoom siv hluav taws xob, feem ntau siv ob lossis ntau tshaj ob lub transformers hauv kev ua haujlwm sib luag. Qhov tseem ceeb ntawm kev ua haujlwm sib luag ntawm transformer yog nyob rau hauv:
1. Thaum transformer tsis ua haujlwm, qhov sib txawv tiv thaiv kev ua haujlwm ntawm lub transformer yuav dhia lub siab thiab qis voltage sab hloov ntawm lub transformer thiab tshem tawm lub transformer, thaum lwm yam transformers khiav nyob rau hauv parallel yuav ua hauj lwm mus rau lub continuation ntawm lub hwj chim noj los ntawm cov neeg siv. .
2. Transformer tiv thaiv kev sim lossis kev saib xyuas, tuaj yeem raug tshem tawm los ntawm cov kab ke sib luag, los ntawm tus so ntawm lub transformer kom dais tag nrho cov hwj huam load, tsis yog tsuas yog los xyuas kom meej lub transformer txij nkawm txoj kev npaj, tab sis kuj los xyuas kom meej lub load tsis cuam tshuam ntawm lub hwj chim mov, txhim kho kev ntseeg tau ntawm lub zog hluav taws xob.
3. Txhim kho lub peev xwm ntawm daim phiaj hluav taws xob kom yooj yim xa. Raws li peb paub, lub caij nyoog load ntawm hluav taws xob muaj zog heev. Feem ntau, lub load yog loj nyob rau hauv lub caij ntuj sov thiab me me nyob rau hauv lub caij ntuj no. Nyob rau hauv txoj kev no, nyob rau lub caij ntuj no thaum lub load me me, ib feem ntawm lub parallel transformer tuaj yeem raug tshem tawm los ntawm kev ua haujlwm, uas txo qhov tsis muaj load los ntawm kev ua haujlwm ntawm lub peev xwm loj transformer thiab txhim kho kev ua haujlwm ntawm tag nrho daim phiaj.
Piv txwv li, lub hwj chim mov network xav tau ib tug transformer nrog lub siab tshaj plaws load ntawm 40,000 kVA. Yog hais tias lub transformer nrog lub siab tshaj plaws load ntawm 50,000 kVA raug xaiv, lub transformer yuav tsum nyob rau hauv ib txwm ua hauj lwm txhua lub sij hawm. Yog tias lub tshuab hloov pauv tsis ua haujlwm, nws yuav cuam tshuam rau kev siv hluav taws xob ib txwm siv rau txhua yam khoom siv hauv qab ntawm lub tshuab hloov pauv, uas yuav ua rau muaj kev puas tsuaj loj rau qee lub tuam txhab hluav taws xob uas tsis tso cai rau lub hwj chim tawm, thiab tseem ua rau muaj kev nyab xeeb. Piv txwv li, cov ntaub ntawv khaws cov khoom siv hauv cov ntaub ntawv loj. Thiab thaum lub load txo nyob rau hauv lub caij ntuj no, lub transformer yuav tshwm sim qhov tshwm sim ntawm tus nees loj rub lub tsheb me me. Yog hais tias peb 25000KVA transformers siv nyob rau hauv parallel lag luam, ib tug transformer yuav raug txiav tawm thaum lub load me me, thiaj li yuav txo tau lub transformer' s tsis-load poob thiab reactive load expenditure, thiab zoo heev txhim kho lub hwj chim mov. kev cia siab ntawm lub zog system.
