Iziguquli zesigaba esi-3 ngokuqhelekileyo zine-windings ezi-6-i-3 yokuqala kunye ne-3 yesibini. I-windings ephambili kunye neyesibini inokudibaniswa kwiindlela ezahlukeneyo zokuhlangabezana neemfuno ezahlukeneyo. Kwizicelo eziqhelekileyo, i-windings idla ngokudityaniswa kwenye yeendlela ezimbini ezidumileyo: iDelta okanye iWye.
DELTA Connection
Kunxibelelwano lwe-delta, kukho izigaba ezithathu kwaye akukho cala. Uqhagamshelo lwe-delta oluphumayo lunokubonelela ngomthwalo wesigaba esi-3 kuphela. Umbane wombane (VL) ulingana nombane wokubonelela. Inqanaba langoku (IAB = IBC = ICA) lilingana noLayini lwangoku (IA = IB = IC) yahlulwe ngo-√3 (1.73). Xa isibini se-transformer siqhagamshelwe kumthwalo omkhulu, ongalinganiyo, i-delta yokuqala ibonelela ngebhalansi engcono yangoku yomthombo wamandla wegalelo.
WYE Connection
Kwi-wye uxhumano, kukho i-3-izigaba kunye nokungathathi hlangothi (N) - iingcingo ezine zizonke. Imveliso yoxhumo lwe-wye yenza ukuba i-transformer ibonelele i-voltage ye-3-phase (isigaba ukuya kwisigaba), kunye ne-voltage yemithwalo yesigaba esisodwa, oko kukuthi i-voltage phakathi kwesiphi na isigaba kunye nokungathathi hlangothi. Indawo engathathi hlangothi nayo inokumiselwa ukubonelela ngokhuseleko olongezelelweyo xa lufunwa: VL-L = √3 x VL-N.
I-DELTA / WYE (D/Y)
D/y Izinto eziluncedo
I-delta engundoqo kunye ne-wye yesibini (i-D/y) uqwalaselo igqamile ngenxa yokukwazi kwayo ukuhambisa umthwalo olungelelanisiweyo weentambo ezintathu kwizinto eziluncedo zokuvelisa amandla, ukwamkela izicelo ezahlukeneyo ngokungenamthungo. Olu lungelelwaniso luhlala lukhethwa ukunika amandla kumashishini, amashishini, kunye namacandelo okuhlala axinana kakhulu.
Olu cwangciso luyakwazi ukubonelela zombini isigaba se-3 kunye nesigaba esisodwa kwaye singenza imveliso eqhelekileyo engathathi hlangothi xa umthombo ungekho. Ithintela ngokufanelekileyo ingxolo (i-harmonics) ukusuka kumgca ukuya kwicala lesibini.
D/y Izinto ezingeloncedo
Ukuba i-coil enye kwezintathu iba nempazamo okanye ingasebenzi, inokubeka esichengeni ukusebenza kweqela lonke, kwaye i-30-degree shift shift between primary and secondary windings ingabangela ukuvuthuza okukhulu kwiisekethe ze-DC.
