Luv - Circuit toj ib sab ntawm lub tshuab hloov hluav taws xob AC Voltage), thiab siv cov khoom siv hluav taws xob tau rau lwm sab ntawm cov ntsuas hluav taws xob (nrog tus kais dej ntawm cov ntsuas hluav taws xob). Qhov no yuav ua rau qhov tam sim no nyob rau hauv transformer winding ncav cuag tus nqi ntsuas. Ntsuas cov ntawv thov voltage thiab lub hwj chim, thiab hloov lawv mus rau qhov tseem ceeb ntawm 75 degree. Lub hwj chim no yog lub nra poob ntawm cov hloov pauv, thiab cov ntsuas hluav taws xob yog lub impedance voltage. Qhov kev xeem no yog hu ua luv luv - Circuit Court kuaj ntawm lub transformer.
Lub nra tiag tiag poob ntawm lub transformer tiag tiag yog qhov tseeb tus tooj liab ploj, uas yog cov cua sov poob tsim tawm thaum tam sim no hla ntawm transformer lub windings. Nws yuav cuam tshuam ncaj qha rau qhov kub nce ntawm cov windings thiab lwm qhov chaw. Yog li ntawd, qhov ntau ntawm cov load ploj tau muaj qhov cuam tshuam tseem ceeb ntawm kev lag luam lag luam ntawm cov transformer.
Impedance voltage (luv - Circuital voltage) yog qhov hluav taws xob thov thaum lub sijhawm luv- Circuit Court. Nws yog ib qho ntawm cov theem pib rau kev ua haujlwm sib txuas ntawm cov hloov pauv. Thaum lub sijhawm luv luv tshwm sim hauv cov kab ke, luv {{4 4}} Circuit Court tam sim no ntawm lub zog hluav taws xob ntawm lub zog ntawm cov impedance voltage. Thaum lub thauj ntawm cov kev hloov pauv hloov pauv tseem ceeb thaum lub sijhawm ua haujlwm, lub impedance voltage ncaj qha cuam tshuam rau lub network hloov pauv.
Lub sijhawm luv - Circuit Court kuaj ntawm cov tshuab hloov pauv yog tsis tsuas yog ua los ntawm cov chaw tsim khoom, tom qab kev hloov pauv, thiab thaum muaj ntau yam hloov pauv hauv parallel.
Transformer kev sim siab tshaj plaws hauv chaw nres tsheb
Lub hom phiaj ntawm kev sim
Los ntawm luv - Txoj Kev Kuaj Circuit Court, nws yog qhov ua tau los tshawb xyuas seb tus hloov pauv tau muaj cov tsis taus hauv qab no.
(1) Nyob rau hauv ntau yam txav tau ntawm lub transformer (shielding, capting rings, capacing rings, capacing rings, pactse flucetic tau mus txog qhov tseem ceeb uas tsis tau tso cai.
(2) Cover saum toj kawg nkaus ntawm cov roj transformer roj thiab cov khoom siv txuas nrog cov kab tawm ntawm cov kab kev tawm ntawm cov kab muaj ntau dua, thiab cov poob ntxiv tau nce ntxiv.
(3) Qhov kev poob qis dua ntawm mult -}}}}}}}}}}}}}}} Txoj kev sib txuam ntawm cov kev coj ua ntawm cov txheej txheem winding.
Los ntawm kev txheeb xyuas saum toj no, nws tuaj yeem pom tau tias lub nra poob thiab impedance voltage yog cov tsis tseem ceeb thaum lub lag luam ntawm cov transformer. Yog li ntawd, luv luv {- Circuit Court Circuit Court yog qhov tseem ceeb heev thiab tsim nyog.
Kev ntsuas txuj ci
Feem ntau, peb {{- theem hluav taws xob muab hluav taws xob siv hluav taws xob muab tau siv rau kev ntsuam xyuas luv luv.
Thaum lub sijhawm ntsuas, txuas tag nrho cov kev xeem seev thiab meters raws li daim duab. Txuas lub peb {{-} pase fais fab mov rau peb-}} {voltage sab ntawm kev ntsuas transformer. Luv - Circuit Court qhov qis - voltage sab. Tom qab tshuaj xyuas tias cov xaim yog qhov tseeb, maj mam nce cov voltage thiab saib cov ntawv qhia ntawm cov meters. Thaum txhua yam yog qhov qub, tsa lub voltage rau tus nqi rated thiab nyeem cov lus qhia ntawm txhua meter. Yog tias muaj qhov tsis txaus ntseeg nyob hauv peb -}} theem tam sim no, siv lub arithmetic nruab nrab ntawm cov ntsuas me me ntawm cov ntawv siv.
Xeem Yuav Tsum Tau
(1) qhov ntsuas kub kho rau kev sim. Luv - Circuit Court kuaj, zoo li ntsuas ntawm DC kuj, kuj tseem cuam tshuam los ntawm qhov kub. Ua ntej kev sim, qhov ntsuas kub yuav tsum tau sau cia, thiab ntsuas ntsuas yuav tsum hloov dua siab tshiab rau qhov siv kub. Feem ntau, cov ntaub ntawv hloov dua siab tshiab rau tus nqi ntawm 75 degree.
(2) kev kho tshiab rau kev sim. Thaum lub sijhawm luv - Kev kuaj Circuit Court Circuit Court, yuav tsum muaj lub peev xwm rau 5% rau 20% ntawm lub peev xwm ntawm kev ntsuas transformer. Yog tias tus xaib raug txwv tsis pub los ntawm cov xwm txheej thiab tsis tuaj yeem ua tus xeem ntawm qhov ntsuas nyob tam sim no, nws raug tso cai los ua qhov kev xeem ntawm cov kev txo qis tam sim no. Txawm li cas los xij, nws yuav tsum tsis txhob qis dua 25%. Cov qhab xeem yuav tsum hloov mus rau cov khoom poob los ntawm qhov ntsuas uas muaj nyob rau ntawm cov qauv.
Sau ntawv rau mloog
(1) Thaum ntsuas cov twj paj nruag yuav tsum tau ntsuas los ntawm kev hloov pauv, cov polarity ntawm tus hloov pauv tam sim no yuav tsum muaj tseeb, thiab polarity ntawm lub voltermeter kuj yuav tsum muaj tseeb.
(2) Vim tias lub DC tsis kam ntawm lub transformer yog tsawg heev, tus ntoo khaub lig} Circuit Court txoj kab ntawm lub luv {2} Yuav tsum muaj qhov sib txuas ntawd loj thiab kev sib txuas yuav tsum tau ua kom txo tau kev sib cuag.
(3) Thaum lub sijhawm luv {{{- Circuit Court kuaj, yog tias ntsuas kev poob yog qhov ntsuas me me yog qhov kev ntsuas yuav tsum tau coj mus rau hauv tus account thiab kho.
(4) Lub sijhawm luv luv - Circuit Court yog feem ntau ua nyob rau hauv ib puag ncig txias. Rau cov hloov pauv uas tau nyuam qhuav raug coj tawm ntawm kev ua haujlwm, kev xeem tsuas yog nqa tawm thaum cov cua sov poob mus rau cov roj kub. Qhov kev xeem ntev yuav tsum yog luv luv thiab nyeem yuav tsum tau sai sai kom tsis txhob muaj kev cia siab kom tsis txhob muaj kev sib tw ntawm cov coils, uas tuaj yeem cuam tshuam qhov tseeb.
(5) Yog tias muaj tus hloov pauv tam sim no sab hauv lub transformer's bushing, sab ob sab ob yuav tsum yog luv- circuited.
Kev tsom xam thiab kev txiav txim ntawm cov ntawv xeem
(1) Cov lus luv luv - Txoj Kev Kuaj Circuit Court Circuit Court tsuas yog ntsuas ob ntu: lo thiab impedance voltage. Raws li cov kev cai ntawm GB1094: Qhov kev sib txawv uas tau pub rau kev thauj khoom poob yog 10%; Kev pub muaj kev tso cai rau impedance voltage yog 10%.
(2) Lub impedance voltage yog cuam tshuam nrog geometric qhov ntev ntawm winding. Nws yog ncaj qha rau ntau zaus; ncaj qha rau ampere -} psts ib sab ntawm cov transformer; ncaj qha proportional rau tag nrho cov toast thaj chaw puag ncig; Caw tau sib luag rau lub voltage ib tig thiab qhov siab ntawm winding. Qhov ntau ntawm cov impedance voltage tseem muaj feem xyuam rau kev npaj ntawm lub windings. Yog li ntawd, thaum ntsuas cov ntaub ntawv ntsuas tau tsis muaj tseeb, ib qho tuaj yeem nrhiav cov teeb meem los ntawm cov kev sib tham no.
(3) Lub nra poob poob muaj kev tiv thaiv tsis kam thiab poob ntxiv. Feem ntau, kev poob ntxiv yog lub ntsiab tivthaiv. Qhov laj thawj rau qhov no yog thaum lub sijhawm tsim khoom, muaj cov kab ke luv ntawm cov strands ntawm cov hluav taws xob winding thiab luv luv ntawm theem.
