Kuaj covtsis muaj - phoo ntawv poobntawm ib transformer (tseem hu ua cov tub ntxhais ploj lossis hlau poob) yog cov txheej txheem tseem ceeb hauv kev ua haujlwm tau zoo thiab kev ua tau zoo ntawm transformer. Tsis muaj {{{1} kev thauj khoom}}} thau khoom poob rau lub zog uas ploj hauv lub transformer thaum muaj kev sib txuas nrog nws sab ob. Cov kev poob no feem ntau tshwm sim los ntawm kev sib xyaw ua ke tam sim no yuav tsum ua kom cov tub ntxhais thiab los ntawm hysteresis thiab eddy ntws hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom tseem ceeb hauv cov khoom.
Ntawm no yog ib kauj ruam - {{1} {}}} kauj ruam qhia rauYuav sim ua li cas tsis muaj - ntim poob ntawm lub transformer:
1. Kev npaj rau kev sim
Ua ntej ua qhov tsis muaj - phoo} phoo ntawv log, kom cov hauv qab no:
Xyuas kom cov transformer yog disconnected los ntawm txhua load: Tus hloov pauv yuav tsum yog tsis muaj - phoo ntawv txias, txhais tau tias tsis muaj tam sim no yog kos los ntawm cov windings thib ob.
Txheeb xyuas kev ntsuas kev nyab xeeb: Ua raws li txhua qhov kev ceev faj tsim nyog. Transformers ua haujlwm ntawm cov khoom rwb thaiv tsev siab, yog li kom ntseeg tau tias cov khoom siv tiv thaiv tus kheej (PPE), thiab kev nyab xeeb cov txheej txheem ua haujlwm nyob rau hauv qhov chaw.
2. Kuaj teeb
Rau qhov tsis muaj {- bread poob kev kuaj, koj yuav tsum tau txuas lub transformer rau ib qho chaw ntsuas hluav taws xob thawj (feem ntau, ac). Cov teeb tsa muaj xws li:
Kev pab fais fab: Ib qho ruaj khov AC muaj peev xwm uas tuaj yeem muab cov ntsuas hluav taws xob ntawm lub transformer.
Volthawjeter: Los ntsuas cov tswv yim voltage.
Tus ammeter: Txhawm rau ntsuas qhov tsis muaj - phoo tam sim no ntawm thawj sab.
Tus tsiaj tsis dim: Los ntsuas cov tswv yim tawm (uas sib raug rau qhov tsis muaj - phoo poob).
Cov khoom siv sib txawv (yeem): Lub zog kws ntsuam xyuas hluav taws xob kuj tseem siv tau los ntsuas cov khoom siv hluav taws xob, tam sim no, thiab lub zog ua ke.
3. Ua cov tsis muaj - deb chaw ntsuam xyuas
Ntawm no yog cov txheej txheem rau ua qhov kev xeem:
a) Thov siv cov ntsuas hluav taws xob thawj
Txuas cov theem tseem ceeb ntawm lub transformerRau AC Fais Fab Qhov Siv thiab siv cov ntsuas hluav taws xob rau cov thawj cua. Qhov winder thib ob yuav tsum nyob twj ywm qhib (tsis muaj thauj khoom).
Xyuas kom cov khoom siv hluav taws xob yog qhov ruaj khovNtawm tus nqi ntsuas rau lub transformer.
b) Ntsuas cov hwj huam tawm
Siv cov wattmeterTxhawm rau ntsuas tag nrho cov tswv yim lub zog rau cov transformer ntawm thawj sab. Qhov no yog lub zog tau noj los ntawm tus hloov pauv thaum ua haujlwm hauv qab tsis muaj - kev thauj khoom.
Lub hwj huam ntsuas (hauv watts) sawv cev tsis muaj - phoo ntawv} Tsis txhob hu ua cov tseem ceeb), uas muaj:
Hysteresis poob: Poob vim yog cov khoom sib nqus ntawm cov khoom siv tseem ceeb.
Eddy tsis tam sim no poob: Poob tshwm sim los ntawm kurtrents inducts hauv cov khoom tseem ceeb vim yog teb sib nqus.
c) Kev ntsuas tsis muaj - ntim tam sim no (yeem)
Siv AmmeterTxhawm rau ntsuas qhov tsis muaj - ntim khoom tam sim no nyob rau hauv thawj winding. Thaum lub sijhawm no tsis yog siv tau ncaj qha los xam tsis muaj - phoo ntawv poob, nws tuaj yeem pab tau cov hlau nplaum tam sim no uas tsim nyog rau lub transformer tus core.
Tsis muaj {- ntim tam sim no feem ntau piv rau tag nrho 1-2}} qhov rated puv {} lead tam sim no.
4. Tsis muaj {{{0} butt freculation
Qhov tsis muaj {{{0} log poob pnlp_ {nl} pnl yog ntsuas ncaj qha los ntawm lub wattmeter raws li tusCov Khoom Siv Hluav Taws XobNyob rau hauv tsis muaj - kev thauj khoom.
= v × i} V \\ {power} pnow {} v × i × tswv yim muaj zog
Qhov twg:
Pnlp_ {nl} pnl=Tsis muaj - lub nra poob (hauv watts)
Vvv=voltage (hauv volts)
Iii {{= Tsis muaj - LOAD tam sim no (hauv amperes)
Lub zog ua tiav=ratio ntawm lub zog tiag tiag rau pom meej lub zog, uas tuaj yeem muab tau los ntawm cov wattmeter nyeem ntawv lossis ntsuas ntsuas siv lub zog hluav taws xob.
Qhov tsis muaj {{{0} Kev ntim khoom poob yog ib qho tseem ceeb ntawm kev hloov pauv ntawm tus tub ntxhais ua haujlwm thiab qhov zoo ntawm nws cov ntaub ntawv tsim kho.
5. Txhais ntawm cov txiaj ntsig
Qhov tsis muaj {{{0} Kev ntim khoom poob yog feem ntau tsis muaj kev hloov pauv tsis tau hais txog ntawm kev thauj khoom ntawm lub transformer (tsuav yog thawj voltage yog tas mus li). Txawm li cas los xij, qhov ntau ntawm cov poob yog nyob ntawm:
Hom kev hloov pauv (piv txwv li, faib khoom lossis hluav taws xob hloov).
Cov khoom siv tseem ceeb siv (piv txwv li, silicon steel, amorphous steel, thiab lwm yam).
Tus qauv tsim thiab kev tsim kho cov hloov pauv (piv txwv li, kev tsim qauv cua, kev tsim kho tseem ceeb, thiab lwm yam).
6. Kev sib piv nrog cov chaw tsim khoom yog cov kev qhia tshwj xeeb
Thaum tsis muaj {{0} butlock poob yog ntsuas, piv nws nrog cov qauv kev lag luam tshwj xeeb thiab kev ntaus nqi. Yog tias ntsuas tus nqi ntsuas tau ntau dua li qhov xav tau, nws tuaj yeem qhia cov teeb meem nrog cov transformer, xws li:
Txoj kev ua haujlwm tseem ceeb: Vim yog cov khoom siv tsis txaus lossis tsim qauv.
Rwb Thaiv Hniav Winding: Uas tuaj yeem ua rau poob ntxiv.
Laus lossis degradation ntawm cov khoom siv tseem ceeb.
7. Ntawv sau
Sau tag nrho cov kev ntsuas (voltage, hluav taws xob, lub zog, muaj cov ntaub ntawv muaj zog, xws li qhov kub thiab txias (uas tuaj yeem cuam tshuam rau cov tub ntxhais poob). Cov ntaub ntawv no tseem ceeb heev rau cov kev ua haujlwm ntawm cov kev ua haujlwm ntawm kev hloov pauv thiab kev saib xyuas yav tom ntej lossis kev nyab xeeb.
Tag
Kuaj qhov tsis muaj {{0} log poob ntawm lub transformer yog qhov ntsuas ncaj qha los ntsuas qhov ua tau zoo thiab ua tau zoo ntawm transformer nyob rau hauv tsis muaj - kev mob. Los ntawm kev thov cov ntsuas hluav taws xob rau thawj sab thiab ntsuas lub zog tawm tswv yim, koj tuaj yeem txiav txim siab cov tub ntxhais ploj thiab xyuas kom cov hloov pauv tau cov qauv tshwj xeeb. Tsis tu ncua tsis - kev ntsuas ntawm cov teeb meem thaum ntxov, ua kom muaj peev xwm ua tau zoo dua ntawm kev hloov pauv lub neej.
