Kwihlabathi lanamhlanje elikhawulezayo, umbane ube yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla. Ukusuka ekunikezeni amandla emakhaya ethu ukuya ekufakeni amandla kwiindawo zethu zokusebenza, umbane udlala indima ebalulekileyo ekuvumeleni indlela yethu yokuphila yanamhlanje. Nangona kunjalo, ngenxa yemfuno eqhubekayo yombane kuza nesidingo esingxamisekileyo sokhuseleko. Kule bhlog, siza kuhlola ukubaluleka kwe-circuit breaker ekugcineni iinkqubo zombane zikhuselekile kunye nendlela esebenza ngayo njengomqobo kwiingozi ezinokubakho. Ngoko ke, masingene kwihlabathi le-circuit breakers kwaye sifunde indlela ezinokusinika ngayo uxolo lwengqondo.
Umqhekezi weSekethe: Umkhuseli wamandla
Isixhobo sokwaphula iisekethe sisixhobo esenzelwe ukulawula nokukhusela iisekethe zombane kwi-overcurrent, sithintela umonakalo kwizixhobo, kwiintambo kunye neengozi zomlilo ezinokubakho. Sisebenza njengomlamli obalulekileyo phakathi komthombo wamandla kunye nezixhobo zombane, sihlala sijonga ukuhamba kombane.
Omnye wemisebenzi yayo ephambili kukukhubeka nokuvula isekethe xa kufunyenwe umsinga ongaqhelekanga. Oku kuthintela iingcingo ukuba zingatshisi kakhulu kwaye zibe yingozi yomlilo. Iziphuli zesekethe “ziphula” iisekethe ngokukhawuleza nangokuchanekileyo, zinyusa ukhuseleko kwaye zinciphisa umonakalo onokubakho.
Kukho iintlobo ezininzi zee-circuit breakers, kuquka ii-thermal circuit breakers, ii-magnetic circuit breakers, kunye nee-combined circuit breakers. Ii-thermal circuit breakers zisebenzisa ii-bimetal strips ezikhula xa zishushu kwaye zikhubekise i-breaker. Ii-magnetic circuit breakers, kwelinye icala, zixhomekeke kwisenzo se-electromagnetic ukuze ziphendule ngokukhawuleza kwi-current surges. Ii-combined circuit breakers zidibanisa izinto ze-thermal kunye ne-magnetic ukubonelela ngenkqubo yokukhusela epheleleyo.
Ukongeza,iziphuli zeseketheZidlala indima ebalulekileyo kwiziganeko zokuqhambuka kombane ezibangelwa kukubethwa ngumbane okanye ziimpazamo zombane. Ngokuphazamisa ngokukhawuleza ukuhamba kombane, zikhusela izixhobo zethu kunye neenkqubo zombane ekonakaleni okuvela kwii-voltage spikes.
Iingenelo zee-circuit breakers
Ukutyala imali kwinkqubo ye-circuit breaker ethembekileyo kuneenzuzo ezininzi ngaphandle kokukhusela umbane ogqithisileyo.
1. Ukhuseleko oluphuculweyo: Iziphuli zesekethe azithinteli nje kuphela umlilo kunye nomonakalo wombane, kodwa zikwakhusela abasebenzi ekutshatyalalisweni ngumbane. Zibonelela ngokhuseleko olongezelelekileyo, ingakumbi kumakhaya anabantwana abancinci okanye izilwanyana zasekhaya.
2. Ukulula kokusetyenziswa: Ngokungafaniyo neefusi, ezifuna ukutshintshwa ngalo lonke ixesha zivuthuza, ii-circuit breakers zinokusetwa kwakhona ngokulula ngeswitshi elula. Oku kulula konga ixesha kunye nomgudu kwaye kuqinisekisa ukunikezelwa kombane okungaphazanyiswa.
3. Ukuchonga iimpazamo: Ii-circuit breakers zineengenelo ezikhethekileyo ekuchongeni ii-circuit ezinengxaki. Ngokuchonga ii-circuit ezinengxaki, ukulungiswa kungenziwa ngokukhawuleza, kuncitshiswe ixesha lokungasebenzi kwaye kuphuculwe ukusebenza kakuhle kwenkqubo yombane.
4. UkuSebenza kakuhle kweendleko: Ukutyala imali kwinkqubo yokwaphula iisekethe esemgangathweni ophezulu kunokubangela ukonga okukhulu kweendleko ekuhambeni kwexesha. Ngokuthintela imililo yombane kunye nomonakalo wezixhobo, basusa isidingo sokulungiswa okubizayo okanye ukutshintshwa.
Isiphelo
Iziphuli zeseketheazikho nje izixhobo, zingabalindi bamakhaya ethu neendawo zethu zokusebenza. Zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko lweenkqubo zamandla, zithintela iingozi kwaye zisuse iingozi ezinokubakho. Ukufaka inkqubo ye-circuit breaker kwindawo yakho yokuhlala okanye yorhwebo kutyalo-mali kukhuseleko noxolo lwengqondo.
Ngoko ke kwixesha elizayo xa uvula iswitshi, thatha umzuzwana ujonge isithinteli esithuleyo esikhusela umbane wakho. Ukusuka ekukhubekeni nasekuqhawuleni iisekethe ukuya ekuthinteleni imililo yombane, ii-circuit breakers zisivumela ukuba sonwabele umbane ngelixa zisigcina sikhuselekile. Khumbula, ukhuseleko akufuneki lube yinto ecingelwayo xa kufikwa kwiinkqubo zombane; kufuneka luhlale luphambili.
