Kwinyanga ephelileyo, umnini-ndawo yokuvelisa encinci, uMnu. Carter, udibene nengxaki ecaphukisayo: izibane zendawo yakhe yokusebenzela zazikhubeka ngokuphindaphindiweyo, kwaye nezixhobo zombane zonakala ngamanye amaxesha. Emva kokumema ingcali yombane ukuba ihlole, unobangela oyintloko wawulula ngokumangalisayo—wayefake ngempazamo ii-1P circuit breakers kwi-main power supply loop ezazifuna ukhuseleko lwe-2P. Le mpazamo ayiphazamisanga nje kuphela imveliso kodwa ikwabangele neendleko zokulungisa ezingeyomfuneko. Kwiinjineli ezininzi zombane, abasebenzi bokuthenga, okanye abanini bamashishini amancinci,Ukukhetha inombolo ye-pole efanelekileyo yee-circuit breakers ngumsebenzi osisiseko kodwa obalulekileyoUkhetho olungalunganga lunokukhokelela kwiingozi zokhuseleko, ukusilela kwezixhobo, okanye ukuvalwa kwemveliso. Namhlanje, siza kuhlalutya ngokupheleleyo iimeko zokusetyenziswa kwee-circuit breakers ze-1P, 2P, 3P, kunye ne-4P ukuze sikuncede wenze ukhetho oluchanekileyo.
Okokuqala, yintoni "iNombolo yePole" yeSekethe eqhekezayo?
Inombolo ye-pole ye-circuit breaker ibhekisa kwinani lee-current-carrying poles ezizimeleyo (ii-conductive loops) ezinazo, ezimisela inani lemigca ezinokuyilawula kwaye ziyiqhawule ngaxeshanye. Ngamafutshane, inombolo ye-pole inxulumene ngokuthe ngqo nobubanzi bokhuseleko lwe-circuit kunye nohlobo lwenkqubo yombane ehambelana nayo. Okulandelayo, siza kuhlalutya iimpawu kunye neemeko zokusetyenziswa kwenombolo ye-pole nganye.
I-1P Circuit Breaker: Ifanelekile kwiiSekethe zeSebe zeSigaba esinye kunye noKhuseleko olulula
Iimbonakalo:Ii-circuit breakers ze-1P zilawula kwaye zikhuphe i-live wire (L wire) kuphela, ngaphandle kokubandakanya i-neutral wire (N wire). Zinesakhiwo esilula kwaye zibiza kancinci, ikakhulu zibonelela ngokhuseleko lokugqithisa kunye ne-short-circuit kwii-circuits zesigaba esinye.
Imeko zesicelo:Isetyenziswa kakhulu kwiisekethe zamasebe zesigaba esinye ezinamandla aphantsi kunye nemithwalo elula, njengeesekethe zokukhanyisa kwizakhiwo zokuhlala, iisekethe zesokhethi zezixhobo ezincinci zasekhaya (ezifana nezibane zetafile, iitshaja zefowuni), kunye neesekethe zamasebe zesigaba esinye kwiinkqubo zokukhanyisa zeofisi.
I-2P Circuit Breaker: Ilungele iiSistim eziphambili zeSigaba esinye okanye imithwalo ebalulekileyo
Iimbonakalo:Ii-circuit breakers ze-2P zinokulawula kwaye zikhuphe zombini intambo ephilayo kunye nentambo engathathi cala ngaxeshanye. Xa kuthelekiswa ne-1P, zinoluhlu olubanzi lokhuseleko, ziphepha iingozi ezinokubakho zokutshayiswa kombane ezibangelwa yintambo engathathi cala etshajwa ngenxa yeziphene.
Imeko zesicelo:Ifanelekile kwiiluphu zombane eziphambili zesigaba esinye (ezifana neswitshi ephambili yezindlu zokuhlala), iisekethe zezixhobo ezibalulekileyo zesigaba esinye (ezifana nee-air conditioner, izifudumezi zamanzi, kunye neefriji ezinamandla amakhulu), kunye neesekethe zesigaba esinye ezifuna ukhuseleko oluphezulu (ezifana neesekethe zezixhobo zonyango kwiikliniki ezincinci kunye neesekethe zezixhobo ezichanekileyo kwiilebhu).
I-3P Circuit Breaker: Kwimithwalo yeMizi-mveliso yeNkqubo yeeNtambo ezintathu zeSigaba eSithathu
Iimbonakalo:Ii-circuit breakers ze-3P zenzelwe iinkqubo zombane ezineentambo ezintathu (ngaphandle kwentambo engathathi cala). Zilawula kwaye zikhuphe iintambo ezintathu eziphilayo (L1, L2, L3) ngaxeshanye, zibonelela ngokhuseleko lokugqithisa kunye nolwe-short-circuit kwizixhobo ezineentambo ezintathu.
Imeko zesicelo:Isetyenziswa kakhulu kumashishini emizi-mveliso kunye nemigodi, kwiindawo zokusebenzela, nakwezinye iindawo ezineenkqubo zeengcingo ezintathu ezinamanqanaba amathathu. Izinto eziqhelekileyo zokusetyenziswa ziquka iimoto ezingasebenziyo ezinamanqanaba amathathu, ii-air compressors ezinamanqanaba amathathu, ii-electrical furnaces ezinamanqanaba amathathu, kunye nezinye izixhobo zoshishino ezinamanqanaba amathathu ezingadingi ntambo engathathi cala ukuze kunikezelwe umbane.
I-4P Circuit Breaker: Ifanelekile kwiNkqubo yeeNtambo ezine zeSigaba eSithathu enoKhuseleko lweeNtambo ezingathathi cala
Iimbonakalo:Ii-circuit breakers ze-4P zilawula kwaye ziqhawule iingcingo ezintathu eziphilayo kunye nentambo enye engathathi hlangothi ngaxeshanye, zilungelelanisa neenkqubo zombane ezineentambo ezine ezinezigaba ezintathu. Zinokukhusela ngempumelelo iisekethe kunye nezixhobo xa kuvela iimpazamo kwintambo engathathi hlangothi, ziqinisekisa ukhuseleko lwenkqubo yonke yombane.
Imeko zesicelo:Isetyenziswa kakhulu kwiinkqubo zombane ezineentambo ezine ezinezigaba ezintathu ezifuna ukukhusela intambo engathathi cala, ezifana nokutshintsha okuphambili kwezakhiwo zorhwebo (ezixhasa izixhobo ezinezigaba ezintathu kunye nezixhobo zasekhaya ezinezigaba esinye), iibhokisi zokusasaza iingcingo ezinezigaba ezintathu kwiindawo zokuthenga ezinkulu, amaziko edatha anemithwalo exutyiweyo yezigaba ezintathu kunye nezigaba esinye, kunye nezikhululo zamandla ezintsha (ezifana neenkqubo zokugcina i-photovoltaic kunye nombane) ezifuna ukhuseleko olupheleleyo lweengcingo ezingathathi cala.
Isishwankathelo esiPhambili soKhetho
1. Kwiisekethe zesebe zesigaba esinye (izibane, izixhobo ezincinci):Khetha i-1P;
2. Kwiisekethe ezibalulekileyo zesigaba esinye okanye iilophu eziphambili:Khetha i-2P;
3. Kwizixhobo zoshishino zenkqubo yezintambo ezintathu zesigaba sesithathu (akukho ntambo ingathathi cala):Khetha i-3P;
4. Kwinkqubo yezintambo ezine enamanqanaba amathathu enemithwalo yezintambo ezingathathi cala (izakhiwo zorhwebo, amaziko edatha):Khetha i-4P.
Ukukhetha inombolo yepali yesaphuli sesekethe esifanelekileyo yindlela yokuqala yokuzikhusela kukhuseleko lombane. Ukuba awukaqiniseki malunga nokukhetha inombolo yepali kwimeko yeprojekthi yakho ethile, zive ukhululekileNxibelelana neengcali zethu zobugcisa ukuze ufumane iingcebiso zobungcali kunye nezisombululo ezenzelwe wena.
