Kugesi, isigaba sibhekisela ekusabalalisweni komthwalo. Uyini umehluko phakathi kwamandla kagesi esigaba esisodwa kanye nesigaba sesithathu? Umehluko phakathi kwesigaba sesithathu kanye nesigaba esisodwa ngokuyinhloko usemoyeni otholwa ngohlobo ngalunye lwentambo. Ayikho into efana namandla esigaba ezimbili, okuyinto emangazayo kwabanye abantu. Amandla esigaba esisodwa avame ukubizwa ngokuthi 'isigaba esihlukanisiwe'.
Izindlu zokuhlala zivame ukukhonzwa ngogesi wesigaba esisodwa, kuyilapho izikhungo zezentengiselwano nezezimboni zivame ukusebenzisa ugesi wesigaba ezintathu. Umehluko omkhulu phakathi kogesi wesigaba esisodwa onesigaba ezintathu ukuthi ugesi wesigaba esisodwa uthwala kangcono imithwalo ephezulu. Izimpahla zikagesi zesigaba esisodwa zivame ukusetshenziswa kakhulu lapho imithwalo ejwayelekile ingukukhanya noma ukushisa, kunokuba kube yizimoto zikagesi ezinkulu.
Isigaba Esisodwa
Intambo yesigaba esisodwa inezintambo ezintathu ezitholakala ngaphakathi kwe-insulation. Izintambo ezimbili ezishisayo kanye nentambo eyodwa engathathi hlangothi zinikeza amandla. Intambo ngayinye eshisayo inikeza ama-volts angu-120 kagesi. I-neutral ixhunywe ku-transformer. Isekethe enezigaba ezimbili kungenzeka ukuthi ikhona ngoba iningi lama-heater amanzi, izitofu kanye nemishini yokomisa izingubo zidinga ama-volts angu-240 ukuze zisebenze. Lezi zifunda zinikezwa yizintambo zombili ezishisayo, kodwa lokhu kumane kuyisekethe yesigaba esigcwele esivela kuntambo yesigaba esisodwa. Zonke ezinye izinto zisebenza ngama-volts angu-120 kagesi, okusebenzisa intambo eyodwa eshisayo kanye ne-neutral. Uhlobo lwesekethe olusebenzisa izintambo ezishisayo nezingathathi hlangothi yingakho luvame ukubizwa ngokuthi isekethe yesigaba esihlukanisiwe. Intambo yesigaba esisodwa inezintambo ezimbili ezishisayo ezizungezwe i-insulation emnyama nebomvu, i-neutral ihlala imhlophe futhi kukhona intambo eluhlaza okwesibhakabhaka.
Isigaba Esithathu
Amandla ezigaba ezintathu ahlinzekwa yizintambo ezine. Izintambo ezintathu ezishisayo ezithwala ugesi ongu-120 volts kanye neyodwa engathathi hlangothi. Izintambo ezimbili ezishisayo kanye ne-neutral run emshinini odinga ugesi ongu-240 volts. Amandla ezigaba ezintathu asebenza kahle kakhulu kunamandla esigaba esisodwa. Cabanga ngendoda eyodwa esunduza imoto egqumeni; lesi yisibonelo samandla esigaba esisodwa. Amandla ezigaba ezintathu anjengokuba namadoda amathathu anamandla alinganayo esunduza leyo moto efanayo egqumeni elifanayo. Izintambo ezintathu ezishisayo kusekethe yezigaba ezintathu zinombala omnyama, oluhlaza okwesibhakabhaka nobomvu; ucingo olumhlophe luyi-neutral futhi ucingo oluhlaza lusetshenziswa phansi.
Omunye umehluko phakathi kocingo lwesigaba esithathu kanye nocingo lwesigaba esisodwa lapho kusetshenziswa uhlobo ngalunye lwentambo. Iningi lezindlu zokuhlala, uma kungezona zonke, zinocingo lwesigaba esisodwa olufakiwe. Zonke izakhiwo zezentengiselwano zinocingo lwesigaba esithathu olufakwe enkampanini kagesi. Ama-motor esigaba esithathu anikeza amandla amaningi kunalawo anganikezwa yi-motor yesigaba esisodwa. Njengoba izindawo eziningi zezentengiselwano zisebenzisa imishini nemishini esebenzisa ama-motor esigaba esithathu, ucingo lwesigaba esithathu kumele lusetshenziswe ukusebenzisa izinhlelo. Konke okusemakhaya okuhlala kusebenza kuphela ngamandla esigaba esisodwa njengezindawo zokuxhuma, isibani, isiqandisi ngisho nezinto zikagesi ezisebenzisa ama-volts angu-240 kagesi.
