Kugesi, isigaba sibhekisela ekusatshalalisweni komthwalo.Uyini umehluko phakathi kokunikezwa kwamandla kwesigaba esisodwa kanye nesigaba sesithathu?Umehluko phakathi kwezigaba ezintathu kanye nesigaba esisodwa ngokuyinhloko ku-voltage etholwa ngohlobo ngalunye lwentambo.Awekho amandla ezigaba ezimbili, okuyinto emangalisayo kwabanye abantu.Amandla esigaba esisodwa ajwayele ukubizwa nge-'split-phase'.
Izindlu zokuhlala zivame ukuhlinzekwa ugesi wesigaba esisodwa, kuyilapho izindawo zezohwebo nezimboni ngokuvamile zisebenzisa ukunikezwa kwezigaba ezintathu.Umehluko owodwa oyinhloko phakathi kwesigaba esisodwa esinezigaba ezintathu ukuthi ukunikezwa kwamandla kwezigaba ezintathu kuthwala kangcono imithwalo ephezulu.Izimpahla zamandla esigaba esisodwa zisetshenziswa kakhulu uma imithwalo ejwayelekile ikhanyisa noma ifudumeza, kunezinjini ezinkulu zikagesi.
Isigaba Esisodwa
Intambo yesigaba esisodwa inezintambo ezintathu ezitholakala ngaphakathi kwendawo efakwa ngaphakathi.Izintambo ezimbili ezishisayo kanye nentambo eyodwa engathathi hlangothi inikeza amandla.Intambo ngayinye eshisayo inikeza ama-volts angu-120 kagesi.I-neutral ikhishwa ku-transformer.Isekhethi enezigaba ezimbili cishe ikhona ngoba izishisi eziningi zamanzi, izitofu nezomisi zezingubo zidinga ama-volts angu-240 ukuze zisebenze.Lezi zisekhethi ziphakelwa yizintambo zombili ezishisayo, kodwa lokhu kuyisekhethi yesigaba esigcwele kusuka ocingweni lwesigaba esisodwa.Zonke ezinye izinto zikagesi zisebenza ku-120 volts kagesi, osebenzisa intambo eyodwa kuphela eshisayo kanye ne-neutral.Uhlobo lwesifunda olusebenzisa izintambo ezishisayo nezingathathi hlangothi yingakho luvame ukubizwa ngokuthi isifunda sesigaba sokuhlukaniswa.Intambo yesigaba esisodwa inezintambo ezimbili ezishisayo ezizungezwe yi-insulation emnyama nokubomvu, i-neutral ihlala imhlophe futhi kukhona intambo yaphansi eluhlaza.
Isigaba Ezintathu
Amandla ezigaba ezintathu anikezwa izintambo ezine.Izintambo ezintathu ezishisayo ezithwala amavolthi angu-120 kagesi kanye nenye engathathi hlangothi.Izintambo ezimbili ezishisayo kanye ne-neutral igijima ocezu lomshini oludinga ama-volts angu-240 wamandla.Amandla ezigaba ezintathu asebenza kahle kakhulu kunamandla esigaba esisodwa.Cabanga ngendoda eyodwa iphusha imoto entabeni;lesi yisibonelo samandla esigaba esisodwa.Amandla ezigaba ezintathu kufana nokuba namadoda amathathu anamandla alinganayo aphusha yona leyo moto egqumeni elilodwa.Izintambo ezintathu ezishisayo kumjikelezo wezigaba ezintathu zinemibala emnyama, eluhlaza okwesibhakabhaka nobomvu;ucingo olumhlophe aluthathi hlangothi futhi ucingo oluluhlaza lusetshenziselwa phansi.
Omunye umehluko phakathi kocingo olunezigaba ezintathu nocingo lwesigaba esisodwa ukhathazekile lapho kusetshenziswa uhlobo ngalunye locingo.Iningi, uma kungewona wonke, amakhaya okuhlala ane-single-phase wire efakiwe.Zonke izakhiwo zezohwebo zinezigaba ezintathu zocingo ezifakwe enkampanini kagesi.Amamotho ezigaba ezintathu anikeza amandla angaphezu kwalawo anganikezwa yimoto yesigaba esisodwa.Njengoba izindawo eziningi zentengiso zisebenzisa imishini nemishini esebenzisa amamotho ezigaba ezintathu, ucingo olunezigaba ezintathu kufanele lusetshenziselwe ukusebenzisa amasistimu.Yonke into esendlini yokuhlala isebenza kuphela ngamandla esigaba esisodwa njengezitolo, ukukhanya, isiqandisi ngisho nezinto zikagesi ezisebenzisa amavolthi angama-240 kagesi.
