Ikholomu yezigaba ezintathu eziwumongo iwukubeka amajika amathathu ezigaba ezintathu kumakholomu ayinhloko amathathu ngokulandelana, futhi amakholomu amathathu ayisisekelo nawo axhunywe amajoka ensimbi angaphezulu naphansi ukuze akhe isekethe kazibuthe evaliwe.Ukuhlelwa kwama-windings kuyafana nalokhu kwe-single-phase transformer.Uma kuqhathaniswa nomongo wensimbi onezigaba ezintathu, ikholomu yesigaba ezinhlanu somgogodla inamakholomu amabili ensimbi yegatsha ngaphezulu kwesokunxele nakwesokudla sekholomu yensimbi, ephenduka indawo yokudlula.Ama-windinging wezinga ngalinye le-voltage ngokulandelana anemikhono kumakholomu ayisisekelo amathathu aphakathi ngokwesigaba, kuyilapho ijoka elihlangothini lingenawo ama-winding, ngaleyo ndlela kwakheka i-transformer yekholomu yezigaba ezintathu eziyinhloko.
Ngenxa yokuthi ukuguquguquka kazibuthe kwesigaba ngasinye somgogodla wensimbi wesigaba sesithathu sekholomu emihlanu kungavalwa ngejoka eliseceleni, izifunda ezinozibuthe ezinezigaba ezintathu zingathathwa njengezizimele komunye nomunye, ngokungafani nesiguquli esivamile samakholomu amathathu. lapho amasekhethi kazibuthe esigaba ngasinye ahlobene.Ngakho-ke, uma kunomthwalo we-asymmetric, i-ziro-sequence flux kazibuthe ekhiqizwa i-zero-sequence current yesigaba ngasinye ingavalwa yijoka eseceleni, ngakho-ke i-impedance yayo ye-excitation ye-zero-sequence ilingana neyokusebenza kwe-symmetrical (ukulandelana okuhle) .
Ama-transformer ezigaba ezintathu kanye namakholomu amathathu anamandla aphakathi nendawo amancane ayamukelwa.I-transformer yesigaba esikhulu enezigaba ezintathu ivame ukukhawulelwa ubude bezokuthutha, futhi i-transformer ye-five-column yesigaba ezintathu ivame ukusetshenziswa.
I-aron-shell single-phase transformer inekholomu eyinhloko emaphakathi kanye namakholomu amabili ayinhloko egatsha (ephinde ibizwe ngokuthi amajoka aseceleni), futhi ububanzi bekholomu ewumgogodla ophakathi yisamba sobubanzi bamakholomu amabili ayinhloko yegatsha.Wonke ama-windings abekwe kukholomu eyinhloko emaphakathi, futhi amakholomu amabili ayinhloko egatsha azungeza uhlangothi olungaphandle lwama-winding "njengamagobolondo", ngakho abizwa ngokuthi i-shell transformer.Ngezinye izikhathi ibizwa nangokuthi i-single-phase three-column transformer.
