Isingeniso Kumanethiwekhi Kagesi Anezigaba Ezintathu
Amagridi kagesi anezigaba ezintathu yiwona asetshenziswa kakhulu emhlabeni jikelele, kokubili embonini kanye nakumagridi kagesi amakhulu. Lezi zinhlelo zinikeza izinzuzo eziningana ezibalulekile kunezinhlelo zesigaba esisodwa, okuhlanganisa ukusebenza kahle kwamandla okuphezulu kanye nekhono lokuletha amandla amakhulu. Kulesi sihloko, sizoxoxa ngemiqondo eyisisekelo yamagridi kagesi anezigaba ezintathu, izingxenye zawo eziyinhloko, izinzuzo zawo, kanye nezinye izinhlelo zokusebenza ezisebenzayo.
Umqondo Oyisisekelo Wenethiwekhi Kagesi Yezigaba Ezintathu
Empeleni, igridi yamandla enezigaba ezintathu iyindlela yokusatshalaliswa kwamandla esebenzisa izintambo noma ama-conductor amathathu ukuthwala ugesi. Umqhubi ngamunye uphethe isignali kagesi ngesimo se-waveform ye-sinusoidal ene-phase offset ehlukile, okungukuthi i-0°, i-120°, kanye ne-240°. Ukuhlanganiswa kwala ma-waveform amathathu kukhiqiza ukugeleza kwamandla okuzinzile nokusebenzayo uma kuqhathaniswa nohlelo lwesigaba esisodwa.
Umdwebo wesigaba sohlelo lwezigaba ezintathu ukhombisa ukuthi la magagasi amathathu asebenzisana kanjani. Uma simelela la magagasi kushadi lephayi, sizobona ukuthi akha i-engeli engu-120° komunye nomunye. Isigaba ngasinye sinikeza i-voltage efanayo kodwa ngezikhathi ezahlukene, okuholela ekugelezeni kwamandla okuqhubekayo nokulinganiselayo.
