Isigaba esisodwaukuvuza umgcini(yakhiwei-miniature-circuit-breaker)ayikwazi ukuxhunywa kumjikelezo wezintambo ezine ezinezigaba ezintathu.Ubuchwepheshe bukhethekile,Ukushintshwa kwesigaba esisodwa sokuvuza kwe-MCBkudivayisi yokulungisa ukuvuza ngaphakathi kokutholwa kwe-transformer yamanje elandelanayo ingumugqa wesigaba (ngaphambili) kanye nomugqa ongenalutho wevekhtha yamanje esele, lapho ukuvuza kwamanje kwedlula u-30mA, ngokusebenzisa itheminali ukuze kusetshenziswe idivayisi yokukhubeka, okuphoqa ukukhubeka kwangaphakathi. isenzo sohlelo, ukufeza indima yokulungisa.
Umdwebo wezintambo we2P ukuvuza switchnjengoba kuboniswe ngezansi:
Umvikeli wokuvuza wesigaba esisodwa angaxhunywa kumjikelezo wezintambo ezintathu - isigaba sesine
Iswishi yokuvuza yesigaba esisodwainomugqa wesigaba kanye nokulawula umugqa ongenalutho, kukhona ukulawulwa komugqa wesigaba esihlukile.Nakuba kunomugqa ongenalutho esigabeni sesithathu sokuphakelwa kwamandla kagesi wezintambo ezine, ungakhiwa i-voltage engu-220V enemigqa yezigaba ezintathu ngokuzenzakalelayo, kodwa ayikwazi ukulawula eminye imigqa yezigaba ezimbili.
Umdwebo wezintambo weswishi yokuvuza yezigaba ezine ezinezintambo uboniswa emfanekisweni ongenhla.
Kuyaphawuleka ukuthi ii-switch yokuvuza yezigaba ezintathuh ihlukaniswe 3P kanye 3P+N, theukuvuza switchyalesi sakhiwo ibiza kancane kunokushintsha kwesigaba esisodwa sokuvuza.
Intambo yokufaka amandla engu-3P + N idinga kuphela ukwazi ukuthi intambo emaphakathi ixhunywe ku-N, futhi enye i-L1, L2, L3 ingaxhunywa kutheminali yezintambo.
3 p + N ukuvuza kokugcinwa komugqa ongu-N kuqondile (kungakhathaliseki ukuthi ngokwehlukana kusesimweni sesiteshi), ukuxhumana kufanele kube ngaphambili kwesokunxele, umugqa ongenalutho ngomugqa ku-N, uma iphutha lentambo engu-N libe ngaphambili. ayikwazi ukunakekela isekethe ekhubekayo eqhubekayo inokulungiswa kukagesi.
