Iimitha zombane ezikwinqanaba lesithathu zahlulwe zibe yimitha yocingo enemigangatho emithathu kunye nenqanaba lesithathu leemitha ezineengcingo.Kukho iindlela ezintathu eziphambili zocingo: ukufikelela ngokuthe ngqo, i-wiring ye-transformer yangoku, kunye ne-current and voltage transformer wiring.Umgaqo we-wiring wemitha yesigaba sesithathu ngokubanzi: qhagamshela i-coil yangoku ngokulandelelana kunye nomthwalo, okanye udibanise kwicala lesibini le-transformer yangoku, kwaye udibanise i-coil ye-voltage ngokuhambelana nomthwalo okanye udibanise kwisibini. icala le-voltage transformer.
Isigaba sesithathu senkqubo yocingo, kwinethiwekhi yokusabalalisa i-voltage ephantsi, umgca wokuhambisa ngokubanzi uthatha inkqubo yocingo lwesigaba sesithathu, apho imigca emithathu imele i-A, B, C isigaba sesithathu, kwaye enye ingathathi hlangothi. Umgca N okanye iPEN (ukuba unikezelo lwamandla kwilophu Ukuba indawo engathathi hlangothi yecala isekelwe phantsi, umgca ongathathi hlangothi ukwabizwa ngokuba ngumgca ongathathi hlangothi (igama elidala kufuneka liphetshwe ngokuthe ngcembe kwaye lithiywe njengePEN. umgca awunakubizwa ngokuba ngumgca ongathathi hlangothi ngengqiqo engqongqo).
Kumgca wokuhanjiswa kwesigaba esisodwa esingena kumsebenzisi, kukho imigca emibini, enye ibizwa ngokuba ngumgca wesigaba L, kwaye enye ibizwa ngokuba ngumgca ongathathi hlangothi N. umgca.Kwinkqubo yesigaba sesithathu, xa izigaba ezintathu zilinganisiwe, umgca ongathathi hlangothi (umgca we-zero) awunayo okwangoku, ngoko ubizwa ngokuba yinkqubo yocingo lwesithathu;kwi-380V yenethiwekhi yokusabalalisa i-voltage ephantsi, ukuze ufumane i-220V isigaba-to-isigaba sombane ukusuka kwi-380V isigaba ukuya kwisigaba se-voltage Setha umgca we-N, kwaye ngezinye izihlandlo, ingasetyenziselwa ulandelelwano lwe-zero yangoku. ukufumanisa, ukuze kubekwe iliso kwibhalansi yobonelelo lwamandla lwesigaba esithathu.
Isigaba sesithathu semitha yocingo lomzobo wocingo lwemitha
