Ama-transformer ezigaba ezi-3 ngokuvamile anama-windings okungenani angu-6- ama-primary 3 nama-3 yesibili. Ama-winding ayisisekelo nawesibili angaxhunywa ekucushweni okuhlukene ukuze ahlangabezane nezidingo ezahlukene. Kuzinhlelo zokusebenza ezivamile, ama-winding ngokuvamile axhunywe kokukodwa kokucushwa okubili okudumile: i-Delta noma i-Wye.
DELTA Connection
Ekuxhumekeni kwe-delta, kunezigaba ezintathu futhi akukho hlangothi. Uxhumano lwe-delta oluphumayo lungahlinzeka ngomthwalo wezigaba ezi-3 kuphela. I-voltage yomugqa (VL) ilingana ne-voltage yokunikezela. Isigaba samanje (IAB = IBC = ICA) silingana nolayini wamanje (IA = IB = IC) uhlukaniswe ngo-√3 (1.73). Uma okwesibili kwe-transformer kuxhunywe kumthwalo omkhulu, ongalingani, i-delta eyinhloko inikeza ibhalansi yamanje engcono yomthombo wamandla okokufaka.
WYE Connection
Ekuxhumaneni kwe-wye, kunezigaba ezingu-3 kanye nokungathathi hlangothi (N) - izintambo ezine sezizonke. Ukukhishwa kwe-wye uxhumano kwenza i-transformer inikeze i-voltage ye-3-phase (isigaba-kuya-isigaba), kanye ne-voltage yemithwalo yesigaba esisodwa, okungukuthi i-voltage phakathi kwanoma yisiphi isigaba nokungathathi hlangothi. Iphoyinti elingathathi hlangothi lingasekelwa futhi ukuze kuhlinzekwe ukuphepha okwengeziwe lapho kudingeka: VL-L = √3 x VL-N.
I-DELTA / WYE (D/Y)
D/y Izinzuzo
Ukucushwa kwe-delta eyinhloko kanye ne-wye yesibili (D/y) kugqama ngamandla akho okuletha umthwalo osele osele onezintambo ezintathu kunsiza ekhiqiza amandla, evumela izinhlelo zokusebenza ezihlukahlukene kalula. Lokhu kulungiselelwa kuvame ukukhethwa ukuze kunikezwe amandla emikhakheni yezohwebo, yezimboni, kanye nehlala abantu abaningi.
Lokhu kusetha kuyakwazi ukuhlinzeka ngokulayishwa kwesigaba esingu-3 nesigaba esisodwa futhi kungakha okumaphakathi kokuphumayo okujwayelekile lapho umthombo ungakhanyi. Icindezela ngokuphumelelayo umsindo (i-harmonics) kusukela kulayini kuya ohlangothini lwesibili.
D/y Okubi
Uma ikhoyili eyodwa kwezintathu iba nephutha noma ingasebenzi, ingase ibeke engcupheni ukusebenza kweqembu lonke, futhi ukugudluka kwesigaba samadigri angu-30 phakathi kwama-winding ayisisekelo nakwesibili kungase kubangele ukugeleza okukhulu kumasekhethi e-DC.
