Ukujongana ne-transformer yengozi yesiphaluka esifutshane ekusebenzeni kwansuku zonke, kuyimfuneko ukufumanisa undoqo wengxaki ngokuhlola kunye nokuvavanya. Xa i-transformer inengxaki yesekethe emfutshane ngequbuliso, amacala aphezulu kunye naphantsi kwamandla ombane aya kuxhomekeka kumbane omkhulu okhoyo. Ngexesha elifutshane xa i-breaker circuit ingenalo ixesha lokuqhawula, umbane owenziwe ngumbane wesiphaluka omfutshane, ohambelana nesikwere sangoku, uya kusebenza kwi-transformer winding. La mandla ombane anokwahlulwa abe ngamandla eradial kunye ne-axial force. Kwimeko yesekethe emfutshane, amandla eradial asebenza ekujikeni aya kwenza ukujija kwe-HV kuxhomekeke kuxinzelelo kunye nokujika kwe-LV phantsi koxinzelelo. Ekubeni i-winging yisetyhula, into ejikelezayo ikhubazeka ngokulula phantsi koxinzelelo kunokuba iphantsi koxinzelelo, ngoko ke i-low-voltage winding ikhubazeka ngokulula. Amandla e-axial eveliswe kwimeko yesekethe emfutshane ngequbuliso icinezela ukujikajika kwaye ibangele ukufuduka kwe-axial yee-windings zombane ophezulu kunye nophantsi. I-axial force iphinda isebenze kwi-iron core kunye ne-clamps. Ngoko ke, xa i-transformer ihlupheka ngenxa yesiphaluka esifutshane, i-low-voltage winding kunye ne-balance winding inokwenzeka ukuba ikhubazeke, ilandelwa yi-high-voltage winding, i-iron core kunye ne-clamp. Ukongeza ekujongeni i-windings eziphambili, iintsimbi zentsimbi, ii-clamps kunye nezinye iindawo emva kwengozi ye-transformer ye-short-circuit, uthotho lweengxaki ezinxulumene nazo kufuneka ziqwalaselwe ngexesha lenkqubo yokuphatha:

I-transformer iyisixhobo esisisigxina ekusebenzeni okuqhubekayo, okuthenjelwa ngokuthe tye ekusebenzeni kwaye kunethuba elincinci lokungaphumeleli. Nangona kunjalo, ekubeni ininzi ye-transformers ifakwe ngaphandle, kwaye ichaphazeleka ngumthwalo ngexesha lokusebenza kunye nephutha elifutshane lesiphaluka senkqubo yamandla, iimpazamo ezahlukahlukeneyo kunye neemeko ezingaqhelekanga zenzeka ngokungaqhelekanga ngexesha lokusebenza.

Ilahleko yamandla ye-transformer ihlukaniswe ibe yilahleko yentsimbi kunye nokulahleka kobhedu. Ilahleko yentsimbi ikwabizwa ngokuba yi-no-load loss, eyilahleko esisigxina. Ngokwenene ilahleko eyenziwa yintsimbi yentsimbi (ekwabizwa ngokuba yilahleko yentsimbi, kunye nokulahleka kobhedu kubizwa ngokuba yilahleko yomthwalo).

Iimpazamo zeTransformer zinokuhlulwa zibe ziimpazamo zangaphakathi kunye neempazamo zangaphandle.Iimpazamo zangaphakathi zeTransformer zibhekiselele kwiimpazamo ezenzeka kwitanki yeoli ye-transformer, kubandakanywa isiphaluka-kwisigaba sesiphaluka esifutshane se-winging nganye, i-inter-turn short circuit of winding, i-short circuit fault phakathi kokujija kunye ne-iron core, i-single-pase-grounding fault of Inqanaba elinye lokujika okanye ucingo olukhokelela ngaphandle oludlula kwiqokobhe, impazamo yoqhawulo olujikajikayo, njl njl. Iimpazamo zangaphandle zeTransformer zibhekisa kwiimpazamo ezahlukeneyo ezenzeka kwi-insulating bushing yangaphandle yetanki yeoli ye-oyile kunye neengcingo zayo ezikhokelela ngaphandle, kubandakanya nenqanaba elinye. ukumisa iisekethe ezimfutshane kunye nesigaba ukuya kwisigaba esifutshane phakathi kweengcingo ezikhokelela ngaphandle ezibangelwa yi-flashover okanye i-insulating bushings eyaphukileyo.

01 Inrush yangokuXa i-transformer iqala ukwenziwa amandla, kwenzeka into ebizwa ngokuba yi-magnetizing inrush. Nangona imisinga yokugxalathelana idla ngokungaphazamisi njengemisinga yempazamo, ubude bexesha lemisinga ye-magnetizing inrush ingolandelelwano lwemizuzwana (xa kuthelekiswa namaxesha anempazamo).
