Ngenyanga edlule, umnikazi weshabhu elincane lokukhiqiza, uMnu. Carter, wabhekana nenkinga ekhungathekisayo: isekethe yokukhanyisa yeshabhu lakhe yayikhubeka ngokuphindaphindiwe, futhi imishini kagesi yonakala ngezinye izikhathi. Ngemva kokumema uchwepheshe kagesi ukuthi azohlola, imbangela eyinhloko yayilula ngokumangalisayo—wayefake ngephutha ama-circuit breaker e-1P ku-power supply loop eyinhloko eyayidinga ukuvikelwa kwe-2P. Leli phutha alizange liphazamise ukukhiqizwa kuphela kodwa futhi labangela nezindleko zokulungisa ezingadingekile. Kwabaningi onjiniyela bakagesi, abasebenzi bokuthenga, noma abanikazi bamabhizinisi amancane,Ukukhetha inombolo efanele ye-pole yama-circuit breaker kuwumsebenzi oyisisekelo kodwa obalulekileUkukhetha okungalungile kungaholela ezingozini zokuphepha, ukwehluleka kwemishini, noma ngisho nokuvalwa kokukhiqiza. Namuhla, sizohlaziya ngokuphelele izimo zokusetshenziswa kwama-circuit breaker e-1P, 2P, 3P, kanye ne-4P ukuze sikusize wenze ukukhetha okunembile.
Okokuqala, Iyini "Inombolo Yesigxobo" Se-Circuit Breaker?
Inombolo yepholi ye-circuit breaker ibhekisela enanini lezingodo ezizimele ezithwala ugesi (izihibe zokuhambisa) enazo, ezinquma inani lemigqa engayilawula futhi iyinqamule ngasikhathi sinye. Kalula nje, inombolo yepholi ihlobene ngqo nobubanzi bokuvikelwa kwesekethe kanye nohlobo lohlelo lokunikezwa kwamandla oluzivumelanisa nalo. Okulandelayo, sizohlukanisa izici nezimo zokusetshenziswa kwenombolo ngayinye yepholi.
I-1P Circuit Breaker: Ifanelekela Amasekethe Egatsha Esigaba Esisodwa Anesivikelo Esilula
Izici:Ama-circuit breaker e-1P alawula futhi anqamule intambo ebukhoma (intambo ye-L), ngaphandle kokubandakanya intambo engathathi hlangothi (intambo ye-N). Anesakhiwo esilula nezindleko eziphansi, ikakhulukazi ahlinzeka ngokuvikelwa kokudlula ngokweqile kanye nokwe-short-circuit kuma-circuit esigaba esisodwa.
Izimo Zokusebenza:Isetshenziswa kabanzi kumasekethe egatsha elilodwa anamandla aphansi kanye nemithwalo elula, njengesekethe zokukhanyisa ezakhiweni zokuhlala, amasekethe esokhethi ezinto ezincane zasendlini (njengezibani zetafula, amashaja ocingo), kanye namasekethe egatsha elilodwa ezinhlelweni zokukhanyisa zasehhovisi.
I-2P Circuit Breaker: Ilungele Amasekethe Ayinhloko Esigaba Esisodwa noma Imithwalo Ebalulekile
Izici:Ama-circuit breaker e-2P angalawula futhi anqamule kokubili intambo ephilayo kanye nentambo engathathi hlangothi ngesikhathi esisodwa. Uma kuqhathaniswa ne-1P, anebanga lokuvikela elibanzi kakhulu, egwema izingozi zokushaqeka kukagesi ezingaba khona ezibangelwa intambo engathathi hlangothi eshajwa ngenxa yamaphutha.
Izimo Zokusebenza:Ifanelekela izihibe zokunikezwa kwamandla kagesi zesigaba esisodwa (njengeswishi eyinhloko yemindeni yokuhlala), izifunda ezibalulekile zemishini yesigaba esisodwa (njengeziphephetha-moya, izifudumezi zamanzi, kanye neziqandisi ezinamandla amakhulu), kanye nezifunda zesigaba esisodwa ezidinga ukuvikelwa okuphezulu kokuphepha (njengezifunda zemishini yezokwelapha emitholampilo emincane kanye nezifunda zemishini enembile emalabhorethri).
I-3P Circuit Breaker: Yemithwalo Yezimboni Yesistimu Yezintambo Ezintathu Yezigaba Ezintathu
Izici:Ama-circuit breaker e-3P aklanyelwe izinhlelo zokuphakelwa kukagesi ezinezintambo ezintathu zesigaba sesithathu (ngaphandle kwentambo engathathi hlangothi). Alawula futhi anqamule izintambo ezintathu ezibukhoma (L1, L2, L3) ngasikhathi sinye, ahlinzeka ngokuvikelwa kokulayishwa ngokweqile kanye nokwesikhashana kwemishini enezigaba ezintathu.
Izimo Zokusebenza:Isetshenziswa kakhulu emabhizinisini ezimboni kanye nawezimayini, ezindaweni zokusebenzela, nakwezinye izindawo ezinezinhlelo zezintambo ezintathu zesigaba sesithathu. Izinto ezijwayelekile zokusetshenziswa zifaka phakathi ama-motor angenazo izigaba ezintathu, ama-air compressor esigaba sesithathu, ama-furnace kagesi esigaba sesithathu, kanye neminye imishini yezimboni yesigaba sesithathu engadingi intambo engathathi hlangothi ukuze kuhlinzekwe ugesi.
I-4P Circuit Breaker: Ifanelekela Uhlelo Lwezintambo Ezine Zezigaba Ezintathu Olune-Neutral Wire Protection
Izici:Ama-circuit breaker e-4P alawula futhi anqamule izintambo ezintathu ezibukhoma kanye nentambo eyodwa engathathi hlangothi ngesikhathi esisodwa, azivumelanise nezinhlelo zokuphakelwa kwamandla kagesi ezinezintambo ezine zesigaba sesithathu. Angavikela ngempumelelo izifunda kanye nemishini lapho kuvela amaphutha entanjeni engathathi hlangothi, aqinisekise ukuphepha kohlelo lonke lokuphakelwa kwamandla.
Izimo Zokusebenza:Isetshenziswa kabanzi ezinhlelweni zokuphakelwa kwamandla kagesi ezinezigaba ezintathu ezidinga ukuvikela intambo engathathi hlangothi, njengokushintsha okuyinhloko kwezakhiwo zezentengiselwano (okusekela kokubili imishini yezigaba ezintathu kanye nezinto zasekhaya zesigaba esisodwa), amabhokisi okusabalalisa izintambo ezinezigaba ezintathu ezitolo ezinkulu, izikhungo zedatha ezinemithwalo exubile yezigaba ezintathu kanye nezigaba esisodwa, kanye neziteshi zamandla ezintsha (njengezinhlelo ze-photovoltaic kanye nezinhlelo zokugcina amandla) ezidinga ukuvikelwa okuphelele kwentambo engathathi hlangothi.
Isifinyezo Esiyinhloko Sokukhetha
1. Kwezisekethe zamagatsha zesigaba esisodwa (izibani, izinto zikagesi ezincane):Khetha i-1P;
2. Ngezisekethe ezibalulekile zesigaba esisodwa noma izihibe eziyinhloko:Khetha i-2P;
3. Kwemishini yezimboni yesistimu yezintambo ezintathu yesigaba sesithathu (ayikho intambo engathathi hlangothi):Khetha i-3P;
4. Kwesistimu yezintambo ezine yesigaba sesithathu enemithwalo yezintambo ezingathathi hlangothi (izakhiwo zezentengiselwano, izikhungo zedatha):Khetha i-4P.
Ukukhetha inombolo yepholi ye-circuit breaker efanele kuyindlela yokuqala yokuzivikela yokuphepha kukagesi. Uma ungakaqiniseki ngokukhethwa kwenombolo yepholi yesimo sakho sephrojekthi ethile, zizwe ukhululekileXhumana nabeluleki bethu bezobuchwepheshe ukuze uthole iseluleko sochwepheshe kanye nezixazululo ezenziwe ngokwezifiso.
