    Inani lenqanaba lokwahlula

    Inokwahlulwa ibe yi-transformer yesigaba sesithathu kunye ne-single-phase transformer.Kwinqanaba lesithathu lenkqubo yamandla, ukusetyenziswa ngokubanzi kwesiguquli sesigaba sesithathu, xa umthamo ukhulu kakhulu kwaye uthintelwe yimeko yothutho, kwinkqubo yamandla yesigaba sesithathu ingasetyenziswa kwiqela elinye lesigaba sokuguqula ukwakheka kwenguqu.

     

    Ukugquma ukucalula

    Inokwahlulwa ibe yi-transformer ejikeleza kabini kunye ne-transformer ejikelezayo emithathu.Ngokuqhelekileyo i-transformers i-double-winding transformers, oko kukuthi, kukho i-windings ezimbini kwi-core yentsimbi, enye i-original winding, enye i-second winding.I-Tri-winding transformers ziziguquli ezinomthamo omkhulu (ngaphezu kwe-5600 kVA) ezisetyenziselwa ukuqhagamshela iintambo ezintathu ezahlukeneyo zothumelo lombane.Kwiimeko ezikhethekileyo, kukho kwakhona i-Satons transformers efaka i-windings eninzi.

     

    Ukuhlelwa kolwakhiwo

    Inokwahlulwa ibe yi-iron-core transformer kunye ne-iron-shell transformer.Ukuba ipakethe ejikelezayo kwi-periphery engundoqo yi-core type transformer;Ukuba intsimbi yentsimbi ijikeleze i-periphery of winding, i-iron-clad transformer.Ezi zimbini zahluke kancinane kulwakhiwo, kodwa akukho mahluko ubalulekileyo kumgaqo.Iziguquli zamandla luhlobo olungundoqo.

    I-transformer ikakhulu yenziwe ngumbindi wentsimbi, i-winding, itanki yeoli, umqamelo we-oyile, i-insulation bushing, itephu yokutshintsha kunye ne-gas relay.

     

    Undoqo wentsimbi

    I-iron core iyinxalenye yesekethe yamagnetic ye-transformer.Ilahleko ye-Hysteresis kunye nelahleko ye-eddy yangoku yenziwa ngexesha lokusebenza.Ukuze kuncitshiswe ukulahleka kobushushu kunye nomthamo kunye nobunzima, undoqo uqulunqwe ishidi lensimbi ye-silicon ejikelezayo egotyiweyo enemagnethi ephezulu. i-conductivity engaphantsi kwe-0.35mm.Ngokokulungelelaniswa kokuphefumula kwi-core, kukho uhlobo oluphambili kunye nohlobo lwegobolondo.

    Kwi-transformer yomthamo omkhulu, ukwenzela ukwenza ubushushu obuveliswa yilahleko yentsimbi engundoqo inokuthatyathwa ngokupheleleyo yi-oyile ekhuselayo ngexesha lomjikelo, ukuze kuphunyezwe isiphumo esihle sokupholisa, umjelo weoyile wokupholisa udla ngokubonelelwa. umbindi wentsimbi.

     

    Ukujija

    I-winding and iron core zizinto eziphambili ze-transformer.Ngenxa yokuba kukho ukuchasana kwi-winding ngokwayo okanye ukuchasana koqhagamshelwano kwi-joint, ukushisa kufuneka kuveliswe ngumthetho we-Joule.Ngoko ke, ukuvuthwa akukwazi ukudlula i-current ephezulu kunomlinganiselo olinganisiweyo ixesha elide.Ukongeza, i-short-circuit current iya kuvelisa amandla amakhulu e-electromagnetic kwi-windings kwaye yonakalise i-transformer.Isiseko sayo somoya sinohlobo oluxubileyo kunye nohlobo oludlulayo ezimbini.

    Iimpazamo eziphambili ze-transformer windings yi-short circuit phakathi kokujika kunye ne-short circuit ukuya kwi-shell.Interturn short circuit ikakhulu ngenxa yokuguga kwe-insulation, okanye ngenxa ye-transformer overload kunye ne-short circuit insulation yi-insulation mechanical.Umphezulu weoyile kwi-transformer yehla, ukuze ukujika kubonakale kumphezulu weoyile, i-interturn short circuit nayo inokwenzeka; Ukongeza, xa udlula kwisekethe emfutshane, ngenxa yempembelelo yangoku ye-deformation ejikelezayo, ukuze Ukugquma kukonakala koomatshini, kuya kuvelisa kwakhona i-inter-turn short circuit.Kwimeko ye-interturn short circuit, i-current in short circuit winding inokugqithisa ixabiso elilinganisiweyo, kodwa i-current in the whole winding ayinakudlula ixabiso elilinganisiweyo.Kule meko, isenzo sokukhusela igesi, imeko enzulu, isixhobo sokukhusela umahluko siya kusebenza kwakhona.Isizathu somjikelezo omfutshane weqokobhe kwakhona ngenxa yokuguga kwe-insulation okanye i-oyile efumileyo, i-oyile yehla, okanye ngenxa yombane kunye ukusebenza overvoltage.Ukongezelela, xa kudlula isiphaluka esifutshane kwenzeka, ukujikeleza kuya kuphazamiseka ngenxa ye-over-current, kwaye i-short circuit phenomenon iya kwenzeka kwakhona kwigobolondo.Xa iqokobhe isiphaluka esifutshane, ngokuqhelekileyo isenzo sesixhobo sokukhusela igesi kunye nesenzo sokukhusela umhlaba.

     

    Itanki yamafutha

    Umzimba (i-winding and iron core) ye-oyile-i-immersed transformer ifakwe kwi-tank yeoli egcwele ioli ye-transformer, kwaye itanki yeoli idityaniswe ngamacwecwe ensimbi.Itanki yeoli ye-transformer ephakathi kunye encinci yenziwe ngegobolondo yebhokisi kunye nebhokisi lebhokisi.Umzimba we-transformer ubekwe kwiqokobhe lebhokisi.Isigqubuthelo sebhokisi sinokuvulwa ukuze siphakanyiswe ngaphandle komzimba ukuze sigcinwe.

     

    Iimpawu zokusebenza zokuhlela intetho

    A. Ukongeza kucingo lobhedu kumthamo omncinci, i-low-voltage winding ye-oyile-immersed transformer ngokubanzi ithatha isakhiwo se-cylinder ye-foil yobhedu ejikeleze i-shaft;I-high-voltage winding ithatha isakhiwo se-cylinder ye-multi-layer, ukwenzela ukuba ukuhanjiswa kwe-ampere-turns kulinganiswe, ukuvuza kwamagnetic kuncinci, amandla omatshini aphakamileyo, kwaye ukuxhatshazwa kwe-short-circuit kunamandla.

    B. Amanyathelo okukhawuleza amkelwe kwi-core kunye ne-winding ngokulandelanayo.Iindawo zokuziqinisa ezifana nokuphakama kwesixhobo kunye ne-low-voltage lead wire zonke zixhotyiswe nge-self-locking anti-loosening nuts, kunye nesakhiwo ngaphandle kokuphakamisa i-core yamkelwe ukuba imelane nokutshatyalaliswa kokuthutha.

    C. Coil kunye core usebenzisa vacuum ukomisa, ioli transformer usebenzisa vacuum oyile filter kunye nenkqubo yokutofa oyile, ukuze ukufuma yangaphakathi transformer ukuba ubuncinane.

    D. Itanki yeoli ithatha i-tank corrugated sheet, enomsebenzi wokuphefumla ukuhlawulela ukutshintshwa kwevolumu yeoli ebangelwa ukuguquka kweqondo lokushisa, ngoko ke imveliso ayinayo itanki yokugcina ioli, enciphisa ngokucacileyo ukuphakama kwe-transformer.

    E. Ngenxa yokuba ishidi elithathiweyo lithathe indawo yetanki yokugcina ioli, i-oyile ye-transformer yodwa kwihlabathi langaphandle, ukuze ikhusele ngokufanelekileyo ukungena kwe-oksijini kunye namanzi kwaye iholele ekunciphiseni kokusebenza kwe-insulation.

    F. Ngokwala manqaku angentla apha, i-oyile-i-transformer ayifuni ukutshintsha ioli ekusebenzeni okuqhelekileyo, okunciphisa kakhulu iindleko zokugcinwa kwe-transformer kunye nokwandisa ubomi benkonzo ye-transformer.
