Mamita matatu emagetsi emagetsi akakamurwa kuita matatu-chikamu matatu-waya mita uye matatu-chikamu mana-waya mita.Kune nzira nhatu huru dzekuisa waya: kupinda zvakananga, ikozvino transformer wiring, uye ikozvino uye voltage transformer wiring.Iyo wiring musimboti wemamita matatu-chikamu kazhinji ndeye: batanidza iyo yazvino coil munhevedzano nemutoro, kana kuibatanidza kune yechipiri chikamu cheiyozvino transformer, uye batanidza iyo voltage coil inoenderana nemutoro kana kuibatanidza kune yechipiri. divi revoltage transformer.
Matatu-phase mana-waya sisitimu, mune yakaderera-voltage yekugovera network, tambo yekufambisa inowanzotora matatu-chikamu mana-waya system, iyo mitsara mitatu inomiririra A, B, C nhatu-chikamu, uye imwe yacho ndiyo isina kwayakarerekera. mutsara N kana PEN (kana loop simba rekupa Kana nzvimbo isina kwayakarerekera yedivi yakadzikwa, mutsara usina kwawakarerekera unonziwo mutsara usina kwawakarerekera (zita rekare rinofanirwa kudziviswa zvishoma nezvishoma uye kutumidzwa zita rekuti PEN. Kana risina kudzika, iro rakarerekera mutsetse haugone kunzi mutsara usina kwawakarerekera mupfungwa yakasimba).
Mumutsara we-single-phase transmission line unopinda mushandisi, kune mitsara miviri, imwe inonzi mutsara wechikamu L, uye imwe inonzi inonzi neutral line N. The neutral line inowanzopfuura ikozvino kuti iite loop ikozvino mune imwe-chikamu. line.Muchikamu chetatu-phase system, kana zvikamu zvitatu zvakaenzana, mutsara usina kwawakarerekera (zero line) hauna ikozvino, saka inonzi nhatu-phase four-wire system;mu380V low-voltage distribution network, kuitira kuwana 220V phase-to-phase voltage kubva pa380V phase-to-phase voltage Seta N line, uye mune dzimwe nguva, inogona zvakare kushandiswa zero-sequence current. kuona, kuitira kutarisa kuenzana kwechikamu chetatu chemagetsi.
