Magawo atatu oyambira mita yamagetsi

Mamita amagetsi a magawo atatu amagawidwa mu magawo atatu amamita atatu-waya ndi mamita atatu agawo anayi.Pali njira zitatu zazikuluzikulu zamawaya: njira yolowera mwachindunji, mawaya a transfoma apano, komanso mawaya apano ndi ma voltage transfoma.Mfundo yamawaya a mita ya magawo atatu nthawi zambiri ndi: kulumikiza koyilo yamakono motsatizana ndi katundu, kapena kulumikiza ku mbali yachiwiri ya thiransifoma yamakono, ndikulumikiza koyilo yamagetsi molumikizana ndi katundu kapena kulumikiza ku yachiwiri. mbali ya voltage transformer.

Magawo atatu amawaya anayi, mumayendedwe otsika-voltage ogawa, chingwe chotumizira nthawi zambiri chimatengera magawo atatu amawaya anayi, pomwe mizere itatu imayimira A, B, C magawo atatu, ndipo inayo ndi yopanda ndale. mzere N kapena PEN (ngati mphamvu ya loop Ngati malo osalowerera ndale akhazikika, mzere wosalowererawo umatchedwanso mzere wosalowerera ndale (dzina lakale liyenera kupewedwa pang'onopang'ono ndikutchedwa PEN. Ngati silinakhazikike, osalowerera ndale mzere sungatchulidwe mzere wosalowerera m'lingaliro lokhwima).

Mu mzere wopatsirana wa gawo limodzi lolowera kwa wogwiritsa ntchito, pali mizere iwiri, imodzi imatchedwa mzere wa L, ndipo winayo amatchedwa mzere wosalowerera N. mzere.Mu dongosolo la magawo atatu, pamene magawo atatuwa ali oyenerera, mzere wosalowerera (zero mzere) ulibe panopa, choncho umatchedwa gawo la magawo atatu a waya;mu 380V low-voltage distribution network, kuti mupeze 220V gawo-to-phase voteji kuchokera ku 380V gawo-to-phase voteji Ikani N line, ndipo nthawi zina, imatha kugwiritsidwanso ntchito paziro-sequence current kuzindikira, kuti aziyang'anira kuchuluka kwa magetsi a magawo atatu.
