Amamitha kagesi ezigaba ezintathu ahlukaniswe abe amamitha anezintambo ezintathu anezigaba ezintathu nezigaba ezintathu ezinezintambo ezine.Kunezindlela ezintathu eziyinhloko zokufaka izintambo: ukufinyelela okuqondile, izintambo ze-transformer zamanje, nezintambo zamanje kanye ne-voltage transformer.Isimiso sezintambo zemitha yezigaba ezintathu ngokuvamile sithi: xhuma ikhoyili yamanje ochungechungeni nomthwalo, noma uyixhume ohlangothini lwesibili lwe-transformer yamanje, bese uxhuma ikhoyili ye-voltage ngokuhambisana nomthwalo noma uyixhume kwesesibili. ohlangothini lwe-voltage transformer.
Isistimu yezintambo ezine ezinezigaba ezintathu, kunethiwekhi yokusabalalisa yamandla aphansi, ulayini wokudlulisela ngokuvamile wamukela isistimu yezintambo ezine zezigaba ezintathu, lapho imigqa emithathu imele u-A, B, C isigaba sesithathu, kanti enye i-neutral. ulayini N noma i-PEN (uma ugesi weluphu Uma indawo emaphakathi yohlangothi isekelwe phansi, ulayini ophakathi nendawo ubizwa nangokuthi ulayini ophakathi nendawo (igama elidala kufanele ligwenywe kancane kancane futhi liqanjwe kabusha ngokuthi I-PEN. Uma lingasekelwe phansi, eliphakathi nendawo. umugqa awukwazi ukubizwa ngokuthi umugqa ophakathi nendawo ngomqondo oqinile).
Emugqeni wokudlulisela wesigaba esisodwa ongena kumsebenzisi, kunemigqa emibili, owodwa ubizwa ngokuthi umugqa wesigaba L, kanti omunye ubizwa ngokuthi umugqa ophakathi nendawo N. Ulayini ophakathi nendawo uvamise ukudlula okwamanje ukuze wenze iluphu yamanje esigabeni esisodwa. umugqa.Kuhlelo lwezigaba ezintathu, lapho izigaba ezintathu zilinganisiwe, umugqa ongathathi hlangothi (umugqa we-zero) awunawo okwamanje, ngakho ubizwa ngokuthi uhlelo lwezintambo ezine ezinezigaba ezintathu;kunethiwekhi yokusatshalaliswa kwe-voltage ephansi engu-380V, ukuze kutholwe ugesi wesigaba ukuya kwesigaba esingu-220V kusuka ku-voltage wesigaba ukuya kwesigaba esingu-380V Setha umugqa ongu-N, futhi kwezinye izikhathi, ungase futhi usetshenziselwe ukulandelana kukaziro wamanje. ukutholwa, ukuze kuqashwe ibhalansi yokuphakelwa kwamandla kwezigaba ezintathu.
Umdwebo wezigaba ezintathu wamamitha ezintambo ezine
