Inombolo yesigaba ezohlukaniswa

Ingahlukaniswa ibe yi-transformer yesigaba ezintathu kanye ne-single-phase transformer.Kuhlelo lwamandla olunezigaba ezintathu, ukusetshenziswa okujwayelekile kwe-transformer yezigaba ezintathu, lapho umthamo mkhulu kakhulu futhi uvinjelwe izimo zokuthutha, ohlelweni lwamandla lwezigaba ezintathu lungasetshenziswa eqenjini le-transformer yesigaba esisodwa sesigaba esisodwa se-transformer.

Umoya ukuze uhlukanise

Ingahlukaniswa ibe i-transformer emazombezombe kabili kanye ne-transformer emithathu emazombezombe.Ngokuvamile ama-transformer angama-double-winding transformers, okungukuthi, kukhona ama-windings amabili emgodleni wensimbi, enye iwukuvuthwa kwasekuqaleni, enye i-winding yesibili.Ama-Tri-winding transformers ama-transformer anamandla amakhulu (ngaphezu kuka-5600 kVA) asetshenziselwa ukuxhuma izintambo ezintathu ezihlukene zokudlulisa amandla kagesi.Ezimweni ezikhethekile, kukhona nama-Saton transformers afaka ama-windings amaningi.

Ukuhlukaniswa kwesakhiwo

Ingahlukaniswa ibe yi-iron-core transformer kanye ne-iron-shell transformer.Uma iphakheji elijikajikayo ku-periphery eyinhloko iyisiguquli sohlobo oluyisisekelo;Uma inkaba yensimbi igoqwe endaweni ezungeze amajika, iyi-transformer ene-iron-clad.Zombili zihluke kancane ngesakhiwo, kodwa awukho umehluko obalulekile esimisweni.Ama-Power transformer awuhlobo oluyisisekelo.

I-transformer yakhiwe ikakhulukazi i-iron core, i-winding, ithangi likawoyela, umcamelo kawoyela, i-insulation bushing, i-tap switch kanye ne-gas relay.

Insimbi core

I-iron core iyingxenye yesekethe kazibuthe ye-transformer.Ukulahlekelwa kwe-Hysteresis kanye nokulahlekelwa kwamanje kwe-eddy kukhiqizwa ngesikhathi sokusebenza.Ukuze kwehliswe ukulahlekelwa ukushisa nevolumu nesisindo, umgogodla wakhiwe ishidi lensimbi ye-silicon egoqelwe okusanhlamvu enozibuthe ophezulu. i-conductivity engaphansi kuka-0.35mm.Ngokuvumelana nokuhlelwa kokuvunguza ku-core, kukhona uhlobo oluyisisekelo kanye nohlobo lwegobolondo.

Ku-transformer yomthamo omkhulu, ukuze wenze ukushisa okukhiqizwa ukulahlekelwa kwensimbi kungasuswa ngokugcwele ngamafutha avikelayo phakathi nomjikelezo, ukuze kuzuzwe umphumela omuhle wokupholisa, isiteshi samafutha okupholisa sivame ukuhlinzekwa umgogodla wensimbi.

Ukujikajika

I-winding ne-iron core yizici ezibalulekile ze-transformer.Ngenxa yokuthi kukhona ukumelana ekujikeni ngokwayo noma ukumelana nokuxhumana ekuhlanganyeleni, ukushisa kufanele kukhiqizwe umthetho ka-Joule.Ngakho-ke, ukusonga akukwazi ukudlula okwamanje okuphakeme kunamanje okulinganiselwe isikhathi eside.Ukwengeza, i-short-circuit current izokhiqiza amandla kazibuthe amakhulu kuma-windings futhi kulimaze i-transformer.Ukusonga kwayo okuyisisekelo kunohlobo olujulile kanye nohlobo lokugqagqana izinhlobo ezimbili.

Amaphutha amakhulu we-transformer windings yi-short circuit phakathi kokuphenduka kanye ne-short circuit kuya kugobolondo.I-Interturn short circuit ibangelwa ikakhulukazi ukuguga kwe-insulation, noma ngenxa yokulayisha ngokweqile kwe-transformer futhi ngokusebenzisa i-short circuit insulation ngokulimala komshini.Ingaphezulu likawoyela ku-transformer liyehla, ukuze ukujika kwejika kuvezwe endaweni kawoyela, i-interturn short circuit ingenzeka; ukwahlukanisa kungukulimala kwemishini, kuzophinde kukhiqize isifunda esifushane esiphakathi.Esimeni sesekethe ye-interturn short, i-current in short circuit winding ingase idlule inani elilinganiselwe, kodwa i-current in the whole winding angeke yeqe inani elilinganiselwe.Kulesi simo, isenzo sokuvikela igesi, isimo esibucayi, idivayisi yokuvikela umehluko nayo izosebenza.Isizathu sokujikeleza okufushane kwegobolondo nakho kungenxa yokuguga kokuguga noma umswakama kawoyela, ukwehla kwezinga likawoyela, noma ngenxa yombani kanye ukusebenza overvoltage.Ngaphezu kwalokho, lapho kudlula i-short circuit kwenzeka, i-winding izokhubazeka ngenxa ye-over-current, futhi i-short circuit phenomenon izophinde yenzeke kugobolondo.Uma igobolondo liyisifunda esifushane, ngokuvamile isenzo sedivayisi yokuvikela igesi kanye nesenzo sokuvikela umhlabathi.

Ithangi lamafutha

Umzimba (umgogodla kanye ne-iron core) we-transformer ecwiliswe ngamafutha ufakwe ethangini likawoyela eligcwele uwoyela we-transformer, futhi ithangi likawoyela lishiselwe ngamapuleti ensimbi.I-tank yamafutha ye-transformer ephakathi nendawo encane yenziwe ngegobolondo lebhokisi kanye nesembozo sebhokisi.Umzimba we-transformer ufakwa kugobolondo lebhokisi.Isembozo sebhokisi singavulwa ukuze sikhishwe ngaphandle komzimba ukuze sigcinwe.

Izici zokusebenza zokuhlela inkulumo

A. Ngaphezu kwentambo yethusi yomthamo omncane, i-low-voltage winding ye-transformer ecwiliswe uwoyela ngokuvamile ithatha isakhiwo sesilinda se-foil yethusi ezungeze umgodi;I-high-voltage winding ithatha isakhiwo se-cylinder ye-multi-layer, ukuze ukusabalalisa kwe-ampere-turn kulinganise, ukuvuza kazibuthe kuncane, amandla emishini aphezulu, futhi ukumelana kwe-short-circuit kunamandla.

B. Izinyathelo zokubopha ziyasetshenziswa kumongo kanye nama-winding ngokulandelanayo.Izingxenye zokubopha ezifana nobude bedivayisi kanye nentambo eholayo ene-voltage ephansi konke kufakwe amantongomane avimbela ukuzikhiya, futhi isakhiwo ngaphandle kokuphakamisa umgogodla siyamukelwa ukuze simelane nokushaqeka kwezinto zokuhamba.

C. Ikhoyili nomgogodla usebenzisa i-vacuum drying, uwoyela we-transformer usebenzisa isihlungi samafutha we-vacuum kanye nenqubo yokujova uwoyela, ukuze umswakama wangaphakathi we-transformer ube ubuncane.

D. I-tank kawoyela yamukela ishidi likathayela, elinomsebenzi wokuphefumula wokunxephezela ukushintshwa kwevolumu yamafutha okubangelwa ukushintsha kwezinga lokushisa, ngakho umkhiqizo awunalo ithangi lokugcina uwoyela, okunciphisa ngokusobala ukuphakama kwe-transformer.

E. Ngenxa yokuthi ishidi likathayela lithathe indawo yethangi lokugcina uwoyela, uwoyela we-transformer uhlukanisiwe nezwe langaphandle, ukuze uvimbele ngempumelelo ukungena komoyampilo namanzi futhi kuholele ekwehleni kokusebenza kokushisa.

F. Ngokusho kwamaphuzu amahlanu angenhla, i-transformer egxiliwe ngamafutha ayidingi ukushintsha amafutha ekusebenzeni okujwayelekile, okunciphisa kakhulu izindleko zokugcinwa kwe-transformer futhi kwandise impilo yesevisi ye-transformer.
