Kumbane, eli nqanaba libhekisa ekusasazweni komthwalo. Yintoni umahluko phakathi kwamandla esigaba esinye kunye nalawo anesigaba sesithathu? Umahluko phakathi kwamandla esigaba sesithathu kunye nalawo anesigaba esinye ngokuyintloko ukwi-voltage efunyanwa ngohlobo ngalunye lwentambo. Akukho nto ibizwa ngokuba ngamandla esigaba esibini, nto leyo ebamangalisayo abanye abantu. Amandla esigaba esinye adla ngokubizwa ngokuba yi-'split-phase'.
Izindlu zokuhlala zihlala zikhonzwa ngumbane wesigaba esinye, ngelixa izakhiwo zorhwebo nezoshishino zihlala zisebenzisa umbane wesigaba sesithathu. Umahluko ophambili phakathi kombane wesigaba esinye kunye nesigaba sesithathu kukuba umbane wesigaba sesithathu ulungelelanisa ngcono imithwalo ephezulu. Izixhobo zombane zesigaba esinye zisetyenziswa kakhulu xa imithwalo eqhelekileyo ilukhanyiselo okanye ukufudumeza, endaweni yeemoto ezinkulu zombane.
Isigaba esinye
Ucingo olunesigaba esinye luneentambo ezintathu ezikwi-insulation. Iintambo ezimbini ezishushu kunye nocingo olunye olungathathi cala zibonelela ngombane. Ucingo ngalunye olushushu lubonelela nge-120 volts yombane. Olungathathi cala lutsalwa kwi-transformer. Isekethe enezigaba ezibini mhlawumbi ikhona kuba uninzi lwezifudumezi zamanzi, izitovu kunye nezomisi zempahla zifuna i-240 volts ukuze zisebenze. Ezi sekethe zondliwa ziintambo ezishushu zombini, kodwa le yisekethe yesigaba esipheleleyo evela kucingo olunesigaba esinye. Zonke ezinye izixhobo zisebenza nge-120 volts yombane, esebenzisa intambo enye eshushu kunye ne-neutral. Uhlobo lwesekethe olusebenzisa iingcingo ezishushu kunye ne-neutral yingakho lubizwa ngokuba yisekethe yesigaba esahlulweyo. Intambo yesigaba esinye ineengcingo ezimbini ezishushu ezijikelezwe yi-insulation emnyama nebomvu, i-neutral ihlala imhlophe kwaye kukho intambo eluhlaza yokumisa.
Isigaba sesithathu
Amandla ezigaba ezintathu anikezelwa ziintambo ezine. Iintambo ezishushu ezintathu ezithwala umbane oyi-120 volts kunye nenye engathathi cala. Iintambo ezishushu ezimbini kunye ne-neutral zisebenza kwisixhobo somatshini esifuna amandla ayi-240 volts. Amandla ezigaba ezintathu asebenza kakuhle kunamandla esigaba esinye. Khawuthelekelele indoda enye ityhala imoto inyuka intaba; lo ngumzekelo wamandla esigaba esinye. Amandla ezigaba ezintathu afana nokuba namadoda amathathu anamandla alinganayo atyhala loo moto inye intaba enye. Iintambo ezishushu ezintathu kwisekethe yezigaba ezintathu zinombala omnyama, oluhlaza okwesibhakabhaka nobomvu; ucingo olumhlophe luyi-neutral kwaye ucingo oluhlaza lusetyenziswa emhlabeni.
Omnye umahluko phakathi kocingo olunezigaba ezintathu kunye nocingo olunezigaba esinye uxhalaba apho kusetyenziswa uhlobo ngalunye locingo. Uninzi lwezindlu zokuhlala, ukuba azikho zonke, zifakelwe ucingo olunezigaba ezintathu. Zonke izakhiwo zorhwebo zifakelwe ucingo olunezigaba ezintathu oluvela kwinkampani yamandla. Iimoto ezinezigaba ezintathu zinika amandla angaphezu kwalawo anokunikezelwa yimoto enesisigaba esinye. Ekubeni uninzi lwezindlu zorhwebo zisebenzisa oomatshini kunye nezixhobo ezisebenzisa iimoto ezinezigaba ezintathu, ucingo olunezigaba ezintathu kufuneka lusetyenziswe ukusebenzisa iinkqubo. Yonke into ekwikhaya lokuhlala isebenza kuphela ngamandla esigaba esinye afana neendawo zokukhupha umbane, isibane, ifriji kwanezixhobo ezisebenzisa umbane oyi-240 volts.
