UkuqondaAbaphuli beeSekethe: Amaqhawe Angadunyiswanga Okhuseleko Lombane
Iziphuli zesekethe zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokusebenza kakuhle kweenkqubo zombane. Ezi zixhobo zenzelwe ukukhusela iisekethe zombane ekugqithiseni kakhulu nakwiisekethe ezimfutshane, ngaloo ndlela zikhusela kwiingozi ezinokubakho. Ukuqonda indlela ezisebenza ngayo iziphuli zesekethe, iintlobo zazo, kunye nokubaluleka kwazo kunokunceda abanini bezindlu kunye neengcali ukugcina imeko-bume yombane ekhuselekileyo.
Yintoni i-circuit breaker?
I-circuit breaker sisitshixo sombane esizenzekelayo esiphazamisa ukuhamba kombane kwisekethe xa sibona imeko engaqhelekanga, efana nokugqithiswa kakhulu okanye i-short circuit. Ngokungafaniyo nee-fuse, ezifuna ukutshintshwa emva kokuba zivuthuzekile, ii-circuit breakers zinokusetwa kwakhona emva kokuba zivuthuzekile, nto leyo eyenza zibe lukhetho olulula nolusebenzayo lokukhusela isekethe.
Zisebenza njani ii-circuit breakers?
Umgaqo osebenzayo we-circuit breaker ulula: ujonga umbane ohamba kwi-circuit. Xa umbane udlula umda obekiweyo, i-circuit breaker iyakhubeka, inqumle umbane. Eli nyathelo lithintela ubushushu obugqithisileyo kunye nemililo enokubakho ebangelwa ngumbane ogqithisileyo. Indlela esebenza ngayo le nto ibandakanya izinto ezinobuzwelo kubushushu okanye ezinobuzwelo kumagnethi.
1. Iziphuli zesekethe ezisebenzisa ubushushu: Ezi zixhobo zisebenzisa umcu we-bimetallic ogobayo xa ufudunyezwa ngumbane ogqithisileyo, ekugqibeleni ubangele iswitshi, uphule isekethe.
2. I-Magnetic circuit breaker: Le circuit breaker isebenza ne-electromagnet. Xa umbane udlula umda okhuselekileyo, i-electromagnet iyanikwa amandla, itsala i-lever ukuvula i-circuit.
Ezinye ii-circuit breakers zanamhlanje zidibanisa imisebenzi yobushushu kunye nemagnethi ukuze zibonelele ngokhuseleko oluphuculweyo kunye nokuphendula ngokukhawuleza.
Iintlobo zee-circuit breakers
Kukho iintlobo ezahlukeneyo zee-circuit breakers, nganye inenjongo ethile:
1. Isixhobo sokwaphula iisekethe esiqhelekileyo: Sifumaneka rhoqo kwiindawo zokuhlala, sisetyenziselwa ukukhusela kwiingxaki zokugqithisa kunye neesekethe ezimfutshane.
2. IiGround Fault Circuit Interruptors (GFCI): Zibalulekile kwiindawo ezimanzi ezifana nezindlu zangasese kunye neekhitshi njengoko zibona iimpazamo zomhlaba kwaye zithintela ukutshayiswa ngumbane.
3. I-Arc Fault Circuit Interrupter (AFCI): Yenzelwe ukuthintela imililo yombane ebangelwa ziimpazamo ze-arc, ii-AFCI ziyafuneka ngakumbi kumakhaya amatsha.
4. IiMiniature Circuit Breakers (iiMCB): Ezi zisetyenziswa kwizicelo zevolthi ephantsi kwaye zilungele ukukhusela isekethe enye.
5. IiResidual Current Breakers (RCCB): Ezi zixhobo zibona ukungalingani kwindlela esebenza ngayo i-current kwaye zibalulekile ekuthinteleni ukutshayiswa ngumbane.
Ukubaluleka kwabaPhuli beeSekethe
Ukubaluleka kwee-circuit breakers akunakugxininiswa kakhulu. Zibalulekile kwezi zinto zilandelayo:
- Ithintela imililo yombane: Ngokuphazamisa ukuhamba kombane ngexesha loxinzelelo olukhulu, iziphuli-mbane zesekethe zinciphisa kakhulu umngcipheko wemililo ebangelwa kukutshisa kakhulu kweentambo zombane.
- KHUSELA IZIXHOBO ZAKHO: Ii-circuit breakers zinceda ekukhuseleni izixhobo zombane neze-elektroniki kumonakalo obangelwa kukunyuka kwamandla okanye iimpazamo.
- Ukhuseleko oluphuculweyo: Xa kukho impazamo, i-circuit breaker ingawunqumla ngokukhawuleza nangokufanelekileyo umbane ukukhusela ukhuseleko lwabantu kunye nepropathi.
- Ukuthobela iMithetho yoMbane: Iikhowudi ezininzi zokwakha zifuna ukufakwa kwee-circuit breakers ukuqinisekisa ukuba imigangatho yokhuseleko iyafezekiswa.
Okukwintsusa
Ngamafutshane, ii-circuit breakers ziyinxalenye ebalulekileyo yeenkqubo zombane zanamhlanje, zibonelela ngokhuseleko olusisiseko kwiingxaki zombane ezigqithisileyo, ii-short circuits, kunye neempazamo zombane. Indlela ezihlala zilungelelaniswa ngayo izenza zibe lukhetho olusebenzayo kwiindawo zokuhlala kunye nezorhwebo. Ukuqonda iintlobo ezahlukeneyo zee-circuit breakers kunye nemisebenzi yazo kunokunceda abantu benze izigqibo zokhuseleko lombane ezikrelekrele ekhaya nasemsebenzini. Njengoko iteknoloji iqhubela phambili, ii-circuit breakers ziya kuqhubeka zikhula, ziphucula ngakumbi indima yazo njengeeqhawe ezingadunyiswanga zokhuseleko lombane.
