Abaphuli beeSekethe: Amaqhawe Angadunyiswanga Okhuseleko Lombane
Kwihlabathi leenkqubo zombane, ii-circuit breakers zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokusebenza kofakelo lonke. Sisixhobo esilula kodwa esinobuchule esenzelwe ukukhusela ii-circuit kumonakalo obangelwa yi-overcurrent kunye nee-short circuits. Ii-circuit breakers zisebenza njengendlela ekhuselekileyo yokungaphumeleli, ziphazamisa ukuhamba kombane xa kufunyenwe iimeko ezingaqhelekanga, ngaloo ndlela zithintela iingozi ezinokubakho ezifana nemililo yombane kunye nomonakalo wezixhobo.
Umgaqo osisiseko we-circuit breaker kukuvula i-circuit ngokuzenzekelayo xa i-current idlula umda othile. Oku kwenziwa ngendlela esebenzisa i-bimetallic strip okanye i-electromagnet ukuwisa i-circuit breaker xa i-overcurrent ifunyenwe. Nje ukuba i-circuit iphazamisekile, i-circuit breaker ingaphinda isetyenziswe ngesandla ukubuyisela ukuhamba, okwenza ibe sisixhobo sokhuseleko esinokuphinda sisetyenziswe.
Kukho iintlobo ezahlukeneyo zee-circuit breakers ezenzelwe ukusetyenziswa ngeendlela ezahlukeneyo, kuquka iindawo zokuhlala, zorhwebo, kunye neendawo zoshishino. Kwizakhiwo zokuhlala, ii-miniature circuit breakers (ii-MCB) zihlala zisetyenziselwa ukukhusela ii-circuit nganye, ezifana nezo zokukhanyisa, izixhobo, kunye nee-sockets. Ezi MCB zincinci kwaye zinokufakwa ngokulula kwiiphaneli zombane, zibonelela ngendlela elula nesebenzayo yokukhusela inkqubo yombane yekhaya.
Kwiindawo zorhwebo nezoshishino, ii-circuit breakers ezinkulu ezifana nee-molded case circuit breakers (MCCB) kunye nee-air circuit breakers (ACB) zisetyenziselwa ukukhusela ii-voltage eziphezulu kunye nee-current circuits. Zikwazi ukusingatha imithwalo emikhulu yombane, ezi circuit breakers zinzima zibalulekile ekuqinisekiseni ukhuseleko kunye nokuthembeka kweenkqubo zombane ezintsonkothileyo kwizakhiwo zorhwebo, iifektri kunye nezityalo zamandla.
Enye yezona nzuzo ziphambili zee-circuit breakers kukukwazi kwazo ukuphendula ngokukhawuleza nangokuchanekileyo kwiimeko zombane ogqithisileyo, ngaloo ndlela zinciphisa umngcipheko weengozi zombane. Ngokungafaniyo nee-fuses, ezifuna ukutshintshwa emva kokusebenza, ii-circuit breakers zinokusetwa kwakhona, nto leyo ezenza zibe sisisombululo esilula nesingabizi kakhulu sokukhusela ii-circuit.
Ukongeza kumsebenzi wazo oyintloko wokukhusela umbane ogqithisileyo, ii-circuit breakers zanamhlanje zibonelela ngeempawu eziphambili ezifana nokukhusela umbane ophantsi komhlaba, ukufumanisa umbane ongaphantsi komhlaba, kunye nokukwazi ukujonga kude. Ezi mpawu zongezelelweyo ziphucula ngakumbi ukhuseleko kunye nokusebenza kweenkqubo zombane, okwenza ii-circuit breakers zibe yinxalenye ebalulekileyo yeziseko zombane zanamhlanje.
Njengoko ubuchwepheshe buqhubeka buhambela phambili, uphuhliso lwee-smart circuit breakers nalo luya lukhula ngamandla. Ii-smart circuit breakers zixhotyiswe ngee-sensors ezakhelwe ngaphakathi kunye nezakhono zonxibelelwano ezizivumela ukuba zibonelele ngedatha yexesha langempela kwiiparameter zombane kunye nemeko yenkqubo. Oku kwenza ukuba kubekho ukugcinwa kwangaphambili kunye nokusombulula iingxaki ezikude, okwandisa ukuthembeka nokusebenza kakuhle kokufakelwa kombane.
Lilonke, ii-circuit breakers zisenokungafumani ngqwalasela rhoqo, kodwa ngokungathandabuzekiyo ziyinxalenye ebalulekileyo ekuqinisekiseni inkqubo yombane ekhuselekileyo nethembekileyo. Ukususela emakhaya ukuya kwizakhiwo zoshishino, ii-circuit breakers zidlala indima ebalulekileyo ekuthinteleni iingozi zombane nokugcina ukuthembeka kweziseko zombane. Njengoko imfuno yezisombululo zombane ezisebenzisa amandla kakuhle nezikrelekrele iqhubeka ikhula, ukubaluleka kwee-circuit breakers ekukhuseleni iinkqubo zombane kuya kubonakala ngakumbi kwiminyaka ezayo.
