Iziguquli zizinto ezibalulekileyo kwiinkqubo zamandla ombane, ezivumela ukuguqulwa nokusasazwa kwamandla ombane ngokufanelekileyo. Phakathi kolungelelwaniso olwahlukeneyo olusetyenziswa kwiziguquli, iDelta (Δ) kunye neWye (Y) uqwalaselo zezona zixhaphakileyo.
Uqwalaselo lweDelta (Δ)
Iimpawu
Kubumbeko lweDelta, udibaniso oluthathu oluphambili olujikajikayo lwenza iluphu evaliweyo efana nonxantathu. Umoya ngamnye uqhagamshelwe ekupheleni ukuya ekupheleni, udala iindawo ezintathu apho i-voltage kwi-winding nganye ilingana nombane womgca.
Iingenelo
Amandla aPhakamileyo aMandla: I-Delta transformers inokusingatha imithwalo ephezulu, ibenze ifaneleke kwizicelo zoshishino.
Ibhalansi yeSigaba: Udibaniso lweDelta lubonelela ngolungelelwaniso olungcono lwenqanaba, olubalulekileyo ekunciphiseni i-harmonics kwiinkqubo zombane.
Akukho Ukungathathi hlangothi: Ukucwangciswa kweDelta akufuni ucingo olungathathi hlangothi, ukwenza lula inkqubo yocingo kunye nokunciphisa iindleko zezinto eziphathekayo.
Usetyenziso
Ngokuqhelekileyo zisetyenziswa kwizicelo zeemoto zemizi-mveliso ngenxa yokukwazi kwabo ukuphatha imisinga ephezulu yokuqalisa.
Ihlala isetyenziswa kwizakhiwo ezinkulu zorhwebo ukukhanyisa kunye nokuhanjiswa kwamandla.
Isetyenziswa rhoqo kwiinguqu ezisezantsi, apho amandla ombane aphezulu kufuneka aguqulwe abe ngamanqanaba ombane asezantsi.
Uqwalaselo lweWye (Y)
Iimpawu
Kuqwalaselo lwe-Wye, enye isiphelo somoya ngamnye sidityaniswe kwindawo eqhelekileyo (engathathi hlangothi), yenza imilo efana neleta "Y." Amandla ombane kumjikelo ngamnye alingana nombane womgca owahlulwe ngengcambu yesikweri sesithathu.
Iingenelo
I-Neutral Point: Ukucwangciswa kwe-Wye kunika indawo engathathi hlangothi, evumela ukusetyenziswa kwemithwalo yesigaba esisodwa ngaphandle kokuchaphazela ibhalansi yesigaba sesithathu.
Umbane weSigaba esisezantsi: I-voltage ye-line-to-neutral iphantsi kune-voltage ye-line-line, enokuba luncedo kwizicelo ezithile.
Ukukhuselwa kwiZiphene eziPhambili: Inqaku elingathathi hlangothi linokuthi lisekelwe, liphucule ukhuseleko kunye nokubonelela ngendlela yeempazamo zamanzi.
Usetyenziso
Isetyenziswa ngokubanzi kwiinkqubo zokuhanjiswa kwamandla okuhlala kunye nezorhwebo.
Ifanelekile ukubonelela amandla kwimithwalo yesigaba esisodwa kwiinkqubo zesigaba sesithathu.
Ngokuqhelekileyo isetyenziswe kwiinguqu ze-step-up, apho i-voltage ephantsi iguqulwa ibe yi-voltage ephezulu yokuhanjiswa.
