Isebenza njani i-transformer egcwele ioyile?

Iitransformer ziyinxalenye ebalulekileyo yesiseko sombane, zinceda ekunyuseni okanye ezantsi i-voltage ukuze kube lula ukuhambisa nokusasaza umbane ngokufanelekileyo. Uhlobo oluqhelekileyo lwetransformer yitransformer egcwele ioyile, esebenzisa ioyile njengendlela yokupholisa nokukhusela umbane. Kodwa isebenza njani itransformer egcwele ioyile, kwaye yintoni eyahlula kwezinye iintlobo zeetransformer? Kweli nqaku, siza kuhlola ukusebenza kwangaphakathi kweetransformer ezizaliswe yioyile, ukusuka kwizinto zazo ezisisiseko ukuya ekusebenzeni kwazo, ukugcinwa kwazo, nokunye.

Iziseko zeeTransformers ezizaliswe yioyile

Iitransformer ezizaliswe yioyile, ezaziwa ngokuba ziitransformer ezizaliswe lulwelo, luhlobo lwetransformer yombane esebenzisa ioyile njengendawo yokukhusela nokupholisa. Uyilo oluzaliswe yioyile lubonelela ngeenzuzo ezininzi, kubandakanya ukuqhuba okuphezulu kobushushu, amandla aphezulu e-dielectric, kunye neempawu zokuziphilisa. Iitransformer ezizaliswe yioyile zihlala zisetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanya ukusasazwa kombane, izibonelelo zoshishino, kunye nezikhululo zeenkonzo.

Izinto ezisisiseko ze-transformer egcwele ioyile ziquka i-core, ii-windings, kunye ne-insulation oil ngokwayo. I-core idla ngokwenziwa ngentsimbi yodidi oluphezulu kwaye ibonelela ngendlela ye-magnetic flux. Ii-windings, ezibandakanya ii-insulated conductors, zijikeleziswa kumbindi ukuze zenze i-magnetic field kwaye zidlulisele amandla ukusuka kwenye i-winding ukuya kwenye. I-insulation oil ayiboneleli nje kuphela ngombane kodwa ikwanceda ekususeni ubushushu obuveliswa ngexesha lokusebenza.

Ukusebenza kweeTransformers ezizaliswe yioyile

Ukusebenza kwe-transformer egcwele ioyile kuqala ngokusetyenziswa komsinga otshintshanayo (AC) kwi-primary winding. Njengoko umsinga we-AC uhamba kwi-primary winding, udala i-magnetic field etshintshayo kwi-core. Le magnetic field etshintshayo ibangela i-voltage kwi-secondary winding, enokunyuka okanye yehle ngokusekelwe kwinani lee-turns kwi-winding nganye.

Njengoko i-transformer isebenza, umbindi kunye nee-windings zifumana ukuqokelelana kobushushu ngenxa yokulahleka kombane. I-oyile yokukhusela idlala indima ebalulekileyo ekutshabalaliseni obu bushushu, ngaloo ndlela igcina i-transformer ngaphakathi kwemida yayo yobushushu. Ukongeza ekutshabalaliseni ubushushu, i-oyile yokukhusela ikwabonelela ngamandla e-dielectric, ithintela ukuqhekeka kombane phakathi kwee-conductors kunye neendawo eziphezulu.

Ukukhusela iOyile kwiiTransformers ezizaliswe yiOyile

Ioyile yokukhusela esetyenziswa kwiitransformer ezizaliswe yioyile idla ngokuba yioyile yeminerali, enika iipropati ezintle kakhulu ze-dielectric kunye nokuqhuba okuphezulu kobushushu. Amandla aphezulu e-dielectric eoyile athintela ukuqhekeka kombane kwitransformer, ngelixa ukuqhuba kwayo kobushushu kunceda ukuhambisa ubushushu kude nombindi kunye nee-windings.

Uphawu olubalulekileyo lweoyile yokukhusela ubushushu kukukwazi kwayo ukuziphilisa. Xa kuvela umbane ngaphakathi kwi-transformer, inani elincinci leoyile liyanyibilika kwaye lenze iigesi ezifana ne-hydrogen kunye ne-methane. Ekuhambeni kwexesha, ezi gesi ziyahlangana kwakhona ukuze ziphinde zivelise ioyile yokukhusela ubushushu, zilungise ngempumelelo nawuphi na umonakalo obangelwe kukukhupha umbane.

Ukuze kugcinwe ukusebenza kakuhle kwe-transformer egcwele ioyile, kubalulekile ukuvavanya rhoqo i-insulating oil ukuze kubonwe iiparameter ezifana namandla e-dielectric, umxholo womswakama, kunye ne-asidi. Ukongeza, ukuthatha iisampulu zeoyile rhoqo kunye nohlalutyo kunokunceda ekuchongeni iingxaki ezinokubakho ngaphambi kokuba zikhokelele ekungasebenzini kwe-transformer.

Iinkqubo Zokupholisa kwiiTransformers ezizaliswe yiOyile

Ukuqinisekisa ukusebenza kakuhle kunye nobude bexesha, ii-transformers ezizaliswe yioyile zixhotyiswe ngeenkqubo zokupholisa ezinceda ekulawuleni ubushushu beoyile yokukhusela kunye ne-transformer iyonke. Kukho iindlela ezininzi eziqhelekileyo zokupholisa ezisetyenziswa kwii-transformers ezizaliswe yioyile, kubandakanya i-convection yendalo, umoya ophoqelelweyo, kunye nokujikeleza kweoyile okuphoqelelweyo.

Ukupholisa i-convection yendalo kuxhomekeke ekujikelezeni kwendalo kweoyile yokukhusela ngaphakathi kwitanki ye-transformer. Njengoko ioyile ifunxa ubushushu obuvela embindini nakwii-windings, iba ncinci kwaye inyuke iye phezulu kwitanki, apho ikhupha ubushushu emoyeni ojikelezileyo. Ioyile epholileyo emva koko ibuyela ezantsi kwitanki ukuze igqibezele umjikelo. Nangona ukupholisa i-convection yendalo kulula kwaye kuthembekile, isenokungafaneleki kwii-transformers ezinamandla aphezulu ezifuna ukupholisa okusebenzayo ngakumbi.

Kwelinye icala, ukupholisa umoya ngokunyanzelwa kusebenzisa iifeni okanye ii-blower ukuhambisa umoya wangaphandle phezu komphezulu wangaphandle wetanki ye-transformer, okwenza kube lula ukudlulisa ubushushu ukusuka kwioyile ukuya emoyeni. Le ndlela idla ngokusetyenziswa kwii-transformers ezincinci kwaye inika isisombululo esingabizi kakhulu sokulawula ukusasazwa kobushushu.

Okokugqibela, ukupholisa ngenkani ukujikeleza kweoyile kubandakanya ukusetyenziswa kweempompo ukujikeleza ioyile yokukhusela ngokusebenzisa izitshintshi zobushushu zangaphandle, apho inokupholiswa ngumoya okanye ngamanzi. Ioyile epholileyo emva koko ibuyiselwa kwitanki yetransformer ukuphinda umjikelo wokupholisa. Le ndlela isetyenziswa rhoqo kwiitransformer ezinkulu kwaye inika ulawulo oluchanekileyo kubushushu beoyile yokukhusela.

Izinto ekufuneka ziqwalaselwe kuLondolozo noKhuseleko

Ukugcinwa ngokufanelekileyo kunye nokuqwalaselwa kokhuseleko kubalulekile ekusebenzeni okuthembekileyo nokukhuselekileyo kwee-transformers ezizaliswe yioyile. Ukuhlolwa rhoqo kwe-transformer, kubandakanya ukuhlolwa okubonakalayo kunye ne-thermographic, kunokunceda ekuchongeni naziphi na iimpawu zokushisa kakhulu, ukuvuza kweoyile, okanye ezinye iingxaki ezinokubakho. Ukongeza, ukuvavanywa rhoqo kweoyile yokukhusela, njengoko kukhankanyiwe ngaphambili, kubalulekile ekuhloleni imeko yayo kunye nokuqinisekisa amandla afanelekileyo e-dielectric.

Izinto eziqwalaselwe ngokhuseleko kwiitransformer ezizaliswe yioyile ziquka amanyathelo okuthintela ukuvuza kweoyile, imililo, kunye nongcoliseko lokusingqongileyo. Kufuneka kubekho amanyathelo aneleyo okuthintela ukuchitheka kweoyile ukuze kuncitshiswe impembelelo yokuchitheka kweoyile. Ngaphezu koko, iinkqubo zokukhusela umlilo, ezifana nezithintelo zomlilo kunye neenkqubo zokucima ngokuzenzekelayo, zinokunceda ukunciphisa umngcipheko womlilo onxulumene netransformer.

Ukuqukumbela, ii-transformers ezizaliswe yioyile ziyinxalenye ebalulekileyo yokusasazwa kwamandla kunye nokusetyenziswa kwemizi-mveliso, zibonelela ngotshintsho olusebenzayo noluthembekileyo lwe-voltage. Ukusetyenziswa kwazo kwe-insulation yeoyile njenge-coolant kunye ne-dielectric medium kuzenza zikwazi ukusebenza kakuhle kwaye zimelane nobunzima bokusasazwa kwamandla ombane. Ngokuqonda imigaqo esisiseko yokusebenza, iimfuno zolondolozo, kunye nezinto eziqwalaselweyo zokhuseleko, kunokwenzeka ukuqinisekisa ukusebenza kwexesha elide kunye nokhuseleko lwee-transformers ezizaliswe yioyile kwizicelo ezahlukeneyo.
