Ewe, ndingakunceda ngaloo nto. Ndingavelisa inqaku ngokusekelwe kwiimfuno ozinikileyo. Nali inqaku:

Iitransformer ziyinxalenye ebalulekileyo ekuveliseni umbane, zinceda ekunyuseni okanye ekwehliseni amanqanaba evolthi ukuze zidlulise umbane ngokufanelekileyo kumgama omde. Ukuqonda umsebenzi weenxalenye zetransformer kubalulekile ekuqinisekiseni ukuthembeka nokusebenza kakuhle kweenkqubo zokusasaza umbane. Kweli nqaku, siza kuhlola iinxalenye zetransformer eziphambili kunye nendima yazo ekuveliseni umbane.

Isiseko

I-core yintliziyo ye-transformer, enika indlela ye-magnetic flux eveliswa yi-primary winding. Ngokwesiqhelo yenziwe ngezinto ezivumela ukugqobhoza okuphezulu njengentsimbi okanye intsimbi, ezinceda ukuvalela i-magnetic field ngaphakathi kwe-core, ngaloo ndlela zonyusa ukusebenza kakuhle kwe-transformer. Uyilo kunye nokwakhiwa kwe-core kubalulekile ekunciphiseni ukulahleka kwamandla kunye nokwandisa ukusebenza kwe-transformer.

I-core idla ngokwakhiwa ngemicu emincinci ye-silicon steel alloy, ehlanganiswa ndawonye ukuze yenze i-constant magnetic circuit. Oku kunciphisa ilahleko ye-eddy current kunye nelahleko ye-hysteresis kwi-core, kuqinisekisa ukuba i-transformer isebenza kakuhle kakhulu. Ubume kunye nobukhulu be-core budlala indima ebalulekileyo ekumiseleni ulawulo lwe-voltage ye-transformer kunye nomthamo wokuthwala umthwalo.

Ukongeza, umbindi udla ngokuyilwa ukunciphisa amanqanaba engxolo kunye nokungcangcazela, ingakumbi kwiitransformer ezinkulu zamandla. Oku kufezekiswa ngobunjineli obucokisekileyo besakhiwo sombindi kunye nokusebenzisa izixhobo zokukhusela ubushushu ukunciphisa naluphi na ungcangcazelo okanye ingxolo enokuvela ngexesha lokusebenza.

IiWindings

Ii-windings zezinye izinto ezibalulekileyo kwi-transformer, equlathe iiseti ezimbini zee-insulated conductors ezijikeleze umbindi. I-primary winding iqhagamshelwe kumthombo wamandla kwaye ithwala i-input voltage, ngelixa i-secondary winding iqhagamshelwe kumthwalo kwaye inika i-output voltage oyifunayo.

Inani leenguqu kwii-windings limisela umlinganiselo wotshintsho lwe-transformer. Ngokutshintsha inani leenguqu kwii-windings eziphambili nezesibini, ii-transformers zinokunyusa okanye zihlise ii-voltage ukuze zihambelane neemfuno zenkqubo yokusasazwa kwamandla.

Ii-conductors ezisetyenziswa kwii-windings zihlala zenziwe nge-copper okanye i-aluminium, njengoko ezi zinto zibonelela ngokuqhuba okuphezulu kunye nokuzinza kobushushu. Ii-windings ziyagqunywa ukuze kuthintelwe ii-short-circuits kunye nokumelana namasimi aphezulu ombane akhoyo ngexesha lokusebenza. Izinto zokukhusela ezifana nephepha, i-varnish, okanye i-epoxy resin zihlala zisetyenziselwa ukukhusela ii-windings kumswakama, uthuli, kunye nezinye izinto ezingqongileyo.

Ukongeza kwiiwindings eziphambili nezesibini, iitransformers zinokuba neewindings ezintathu, ezisetyenziselwa usetyenziso oluthile olufana nokumisa umhlaba okanye ukubonelela ngamandla ancedisayo. Uyilo kunye nolungiselelo lweewindings zibalulekile ekuqinisekiseni amandla etransformer okusingatha imithwalo eyahlukeneyo kunye namanqanaba evolthi ngokulahlekelwa okuncinci.

Umtshintshi weTap

I-tap changer sisixhobo esivumela ukulungiswa kwe-turn ratio ye-transformer ukuze ivumelane notshintsho kumanqanaba e-voltage yenkqubo yamandla. Kubalulekile ekugcineni i-output voltage ehambelanayo phantsi kweemeko ezahlukeneyo zomthwalo, ngaloo ndlela kuphucula uzinzo kunye nokuthembeka kwenethiwekhi yokusasazwa kwamandla.

I-tap changer isebenza ngokutshintsha iindawo zonxibelelwano ze-primary kunye ne-secondary windings, itshintsha ngempumelelo umlinganiselo wotshintsho lwe-transformer. Oku kunokufezekiswa ngeendlela zoomatshini, zombane, okanye ze-elektroniki, kuxhomekeke kuyilo lwe-tap changer.

Iimpompo zoomatshini zezona ziqhelekileyo kwaye zisebenza ngokuhamba kweswitshi yokukhetha ukuqhagamshela iimpompo ezahlukeneyo kwiiwindings. Kwelinye icala, iimpompo zombane neze-elektroniki zisebenzisa iinkqubo zolawulo eziphambili ukuze zifezekise uhlengahlengiso olungenamthungo noluchanekileyo xa kuthelekiswa notshintsho lweemeko zomthwalo kunye nevolthi.

Izixhobo zokutshintsha itephu zanamhlanje zinokubandakanya ubuchule bokubeka esweni kunye nokuxilonga ukubonelela ngempendulo ngexesha langempela malunga nokusebenza kwe-transformer. Oku kuvumela ukugcinwa kunye nokusombulula iingxaki ngokukhawuleza, kunceda ukuthintela ukungaphumeleli kunye nokuphazamiseka kombane.

Inkqubo Yokupholisa

Iitransformer zivelisa ubushushu ngexesha lokusebenza ngenxa yokulahlekelwa okukhoyo kumbindi, kwiingcingo, nakwezinye izinto. Kubalulekile ukucima obu bushushu ngokufanelekileyo ukuze kuthintelwe ubushushu obugqithisileyo nokuqinisekisa ukuthembeka kwexesha elide kwetransformer.

Iinkqubo zokupholisa kwiitransformer zinokwahluka ngokuxhomekeke kumlinganiselo wamandla, ukusetyenziswa, kunye neemeko zokusingqongileyo. Iindlela zokupholisa eziqhelekileyo ziquka iinkqubo ezifakwe kwi-oyile, ezipholisiweyo ngomoya, kunye neenkqubo ezipholisiweyo ngamanzi, nganye ineenzuzo kunye nemida eyahlukileyo.

Iitransformer ezintywilisiweyo kwioyile zisebenzisa ioyile yeminerali okanye ioyile yokwenziwa njengendawo yokupholisa, ejikeleza embindini nakwiingcingo ukuze ifunxe kwaye ikhuphe ubushushu. Ioyile ikwabonelela ngobushushu kwaye ikhusela izinto zangaphakathi kumswakama kunye nezinto ezingcolisayo. Ukugcinwa ngokufanelekileyo kweoyile, kubandakanya ukuvavanywa rhoqo kunye nokuhluzwa, kubalulekile ukuqinisekisa ukusebenza kakuhle kwenkqubo yokupholisa kunye nobude bexesha letransformer.

Iitransformer ezipholisiweyo ngumoya zixhomekeke ekujikelezeni komoya kwendalo okanye okunyanzelekileyo ukususa ubushushu embindini nakwiingcingo. Le ndlela idla ngokusetyenziswa kwiitransformer ezincinci neziphakathi, apho umoya ojikeleze umoya unokubonelela ngokupholisa okwaneleyo ngaphandle kwesidingo seendawo zokupholisa ezongezelelweyo.

Iitransformer ezipholisiweyo ngamanzi zisebenzisa inkqubo evaliweyo enamanzi njengendawo yokupholisa, ejikeleziswa ngeetshaneli okanye izitshintshi zobushushu ngaphakathi kwitransformer. Le ndlela isetyenziswa rhoqo kwiitransformer ezinkulu zamandla kwaye inokususa ngempumelelo imithwalo ephezulu yobushushu xa ithelekiswa nokupholisa umoya okanye ioyile.

Inkqubo yoKhuseleko

Inkqubo yokukhusela umbane yetransformer ibalulekile ekugcineni ukuthembeka kwezixhobo zombane kunye nokuthintela iimpazamo okanye ukonakala. Iqulethe izixhobo ezahlukeneyo zokukhusela umbane kunye nezakhiwo ezenzelwe ukumelana nombane ophezulu, utshintsho lobushushu, kunye noxinzelelo lokusingqongileyo olufunyanwa ngexesha lokusebenza kwetransformer.

Izinto zokukhusela eziqinileyo ezifana nephepha, ibhodi yokucinezela, kunye ne-epoxy resin zihlala zisetyenziselwa ukuthintela ii-windings, i-core, kunye nezinye izinto zangaphakathi. Ezi zinto zikhethwa ngononophelo kwaye zicutshungulwa ukuqinisekisa amandla aphezulu e-dielectric, uzinzo lobushushu, kunye nokumelana nokwaluphala kunye nokuwohloka.

Ukongeza kwi-insulation eqinileyo, ii-transformers zinokufaka i-insulation yolwelo ngendlela yeoyile okanye igesi ukuphucula iipropati ze-dielectric kunye nokunciphisa i-partial discharge phenomena. Uyilo kunye nolungiselelo lwenkqubo ye-insulation lubalulekile ekuthinteleni iindawo ezishushu, ii-short-circuits, kunye nezinye iintsilelo ezinxulumene ne-insulation ezinokubeka emngciphekweni ukusebenza kunye nokhuseleko lwe-transformer.

Ngaphezu koko, inkqubo yokukhusela ubushushu idlala indima ebalulekileyo ekunciphiseni impembelelo yokusingqongileyo, ingakumbi kwiindawo zangaphandle okanye ezivezwe ngaphandle. Ibonelela ngokhuseleko kumswakama, uthuli, kunye nongcoliseko, iqinisekisa ukuba i-transformer ihlala ixesha elide kwaye ithembekile kwiimeko ezahlukeneyo zokusebenza.

Iitransformer zizinto ezibalulekileyo kwiinkqubo zokuvelisa nokusasaza umbane, ezivumela ukuhanjiswa kombane okusebenzayo nokuthembekileyo kumgama omde. Ngokuqonda umsebenzi wezinto zetransformer ezifana ne-core, i-windings, i-tap changer, inkqubo yokupholisa, kunye nenkqubo yokukhusela, iinjineli kunye nabaqhubi banokuphucula ukusebenza kunye nobude bexesha leetransformer kwizicelo ezahlukeneyo.

Ngamafutshane, umbindi usebenza njengendlela yemagnethi, ii-windings ziguqula kwaye zidlulise i-voltage, i-tap changer ilawula amanqanaba e-voltage, inkqubo yokupholisa isusa ubushushu, kwaye inkqubo yokukhusela iqinisekisa ukuthembeka kombane. Icandelo ngalinye lidlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kwe-transformer, ukuthembeka, kunye nokhuseleko, okufaka isandla kuzinzo lulonke lwegridi yamandla.

Iitransformers ziyaqhubeka nokukhula ngokuqhubela phambili kwizixhobo, uyilo, kunye nobuchwepheshe bokubeka esweni, zibonelela ngamathuba amatsha okuphucula ukusebenza kwazo kunye nokusebenza kwazo ekuveliseni umbane. Njengoko imfuno yombane othembekileyo nozinzileyo ikhula, iitransformers ziya kuhlala zigxile kakhulu ekuveliseni izinto ezintsha kunye nokuphucula imboni yamandla.
