Nkag siab txog cov Cheebtsam tseem ceeb ntawm Transformers
Lub transformer yog tsim los ntawm hluav taws xob, sib nqus, insulating, txias, tiv thaiv, thiab kev sib txuas systems uas ua hauj lwm ua ke kom hloov lub zog yam xyuam xim ntawm circuits. Kev nkag siab txog cov ntsiab lus tseem ceeb ntawm lub tshuab hloov pauv yuav pab cov kws tshaj lij, cov neeg yuav khoom, thiab cov chaw tsim khoom paub txog txhua yam ua, vim li cas nws tseem ceeb, thiab qhov twg tsis ua haujlwm feem ntau pib.
Dab tsi yog qhov tseem ceeb ntawm transformer?
Qhov tseem ceeb ntawm lub transformer yog covtub ntxhais, windings, rwb thaiv tsev, tank los yog enclosure, terminals, bushings, txias system, thiab cov khoom tiv thaiv. Hauv cov ntsiab lus yooj yim, cov tub ntxhais muaj cov sib nqus flux, cov windings nqa tam sim no, rwb thaiv tsev cais cov energized thaj chaw, thiab cov qauv txheej tiv thaiv kev sib dhos los ntawm tshav kub, ya raws, thiab kev puas tsuaj.
Core transformer Cheebtsam thiab lawv lub luag haujlwm
Sib nqus core
Cov tub ntxhais hlau nplaum feem ntau yog tsim los ntawm cov hlau laminated tsim los coj cov hlau nplaum sib nqus zoo. Nws cov duab thiab cov khoom cuam tshuam kev poob, cua sov, suab nrov, thiab kev ua haujlwm tag nrho. Ib qhov zoo- tsim cov tub ntxhais yuav pab lub transformer hloov lub zog nrog tsawg pov tseg.
Thawj thiab theem nrab windings
Windings yog coils ntawm cov khoom siv hluav taws xob, feem ntau yog tooj liab lossis txhuas, qhwv ib ncig ntawm cov tub ntxhais. Thawj winding tau txais qhov hluav taws xob nkag, thaum lub tshuab hluav taws xob thib ob xa cov hloov hluav taws xob mus rau lub nra. Qhov sib piv ntawm cov windings no txiav txim seb lub transformer kauj ruam voltage nce los yog down.
Rwb thaiv tsev system
Rwb thaiv tsev yog ib qho tseem ceeb tshaj plaws ntawm cov khoom siv hluav taws xob vim nws khaws cov khoom siv hluav taws xob sib cais. Nws yuav muaj xws li ntawv, pressboard, kua roj vanish, resin, roj, roj, los yog khoom dielectric cov ntaub ntawv nyob ntawm seb hom transformer. Thaum cov rwb thaiv tsev tsis muaj zog, qhov kev pheej hmoo ntawm overheating, arcing, thiab tawg nce.
Tank, enclosure, thiab ncej
Lub tank lossis qhov thaiv thaiv qhov chaw sab hauv los ntawm kev cuam tshuam, kev sib kis, thiab kev cuam tshuam ib puag ncig. Hauv cov roj- cov roj puv, lub tank tseem tuav cov roj insulating thiab txias. Qhuav- hom transformers vam khom ntau dua ntawm cov qhov cua nkag thiab cov khoom siv rwb thaiv tsev.
Kev sib txuas, terminals, thiab bushings
Transformer kev sib txuas txuas lub tsev rau cov khoom nkag thiab tawm. Terminals muab cov ntsiab lus sib txuas, thaum bushings tso cai rau cov neeg ua haujlwm hla kev nyab xeeb los ntawm cov tso tsheb hlau luam hauv av lossis cov ntaub thaiv npog. Vim hais tias kev sib txuas ntawm cov khoom siv hluav taws xob tau nthuav tawm cov khoom siv hluav taws xob hauv qee qhov kev teeb tsa, kev tswj xyuas kev nkag, kev sau npe, hauv av, thiab cov txheej txheem kev pabcuam tsim nyog yog qhov tseem ceeb.
Kev sib txuas tseem ceeb- cov khoom muaj feem cuam tshuam suav nrog:
High -voltage terminalsrau sab khoom siv
Tsawg-voltage terminalsrau sab load
Coj mus rhaub changersrau kho qhov voltage nyob rau hauv ib tug tsim ntau yam
Cov ntsiab lus hauv avlos pab tswj qhov txhaum tam sim no thiab kov voltage
Cable lugs lossis tsheb npav txuasrau kev ruaj ntseg mechanical thiab hluav taws xob tiv tauj
Transformer accessories uas txhim kho kev nyab xeeb thiab kev ua haujlwm
Transformer accessories txhawb kev saib xyuas, cua txias, tiv thaiv, thiab tu. Tsis yog txhua lub transformer suav nrog cov khoom siv tib yam, tab sis cov chav loj lossis ntau qhov tseem ceeb feem ntau xav tau kev saib xyuas ntau dua.
Common transformer accessories muaj xws li:
Conservator lub tank:Tso cai rau cov roj insulating kom nthuav dav thiab cog lus.
Ua pa:Pab txwv cov dej noo nkag mus rau hauv cov roj- cov tshuab puv.
Roj theem taw qhia:Qhia seb cov roj tseem nyob hauv qhov zoo li cas.
Kub ntsuas kub:Saib xyuas winding lossis roj kub.
Cov cuab yeej siv siab:Tso cov siab sab hauv.
Cov kiv cua txias lossis radiators:Pab tshem tawm cov cua sov thaum ua haujlwm.
Buchholz relay:Tshawb xyuas qee qhov kev ua txhaum sab hauv hauv qee cov roj-cov hloov pauv.
Cov khoom ua haujlwm ua ke li cas?
Transformer Cheebtsam ua hauj lwm raws li ib tug system: voltage energizes thawj winding, cov tub ntxhais yog sib nqus flux, thiab lub thib ob winding ua rau cov zis voltage. Rwb thaiv tsev, cua txias, thiab kev tiv thaiv ua rau cov txheej txheem ruaj khov. Yog tias ib qho kev txhawb nqa tsis ua haujlwm, cov khoom siv hluav taws xob tseem tuaj yeem ua haujlwm luv luv, tab sis kev ntseeg siab thiab kev nyab xeeb tuaj yeem poob sai sai.
Daim ntawv teev cov tswv yim rau kev txheeb xyuas qhov chaw transformer
Thaum saib cov transformer, saib rau:
Nameplate ntsuam xyuas thiab daim duab txuas
Thawj thiab theem nrab terminals
