Abaphuli beesekethe: Isiqinisekiso soKhuseleko loMbane

UkuqondaAbaphuli beeSeketheIzixhobo zoKhuseleko ezibalulekileyo kwiinkqubo zombane

Kwihlabathi lobunjineli bombane nokhuseleko, igama elithi “circuit breaker” linentsingiselo eninzi. I-circuit breaker sisitshixo sombane esizenzekelayo esenzelwe ukukhusela i-electrical circuit kumonakalo obangelwa kukugqithisa okanye ii-short circuits. Umsebenzi waso oyintloko kukuphazamisa ukuhamba kombane xa kufunyenwe impazamo, ngaloo ndlela kuthintelwe iingozi ezinokubakho ezifana nemililo yombane okanye umonakalo kwizixhobo. Eli nqaku lijonga ngokunzulu iinkalo ezahlukeneyo ze-circuit breakers, iintlobo zazo, imisebenzi yazo, kunye nokubaluleka kwazo kwiinkqubo zombane zanamhlanje.

Umsebenzi we-circuit breaker

I-circuit breaker ngokuyintloko sisixhobo sokhuseleko kwisekethe yombane. Xa umbane ohamba kwisekethe udlula kwinqanaba elimiselweyo, i-circuit breaker iyakhubeka ngokuzenzekelayo, inqumle umbane. Eli nyathelo libalulekile ekuthinteleni ubushushu obugqithisileyo kunye nemililo enokubakho ebangelwa ngumbane ogqithisileyo. Ngokungafaniyo neefusi, ekufuneka zitshintshwe emva kokuba zivuthuze, ii-circuit breakers zinokuphinda zisetyenziswe emva kokuba zikhubekile, nto leyo eyenza zibe lukhetho olulula nolusebenzayo lokukhusela isekethe.

Iintlobo zee-circuit breakers

Kukho iintlobo ezininzi zee-circuit breakers, nganye yenzelwe usetyenziso oluthile kunye neendawo ezithile. Ezona ntlobo zixhaphakileyo ziquka:

1. I-Miniature Circuit Breaker (MCB): Ezi circuit breakers zisetyenziswa kwiindawo zokuhlala nakwiindawo zorhwebo ukukhusela kwi-overload kunye ne-short circuits. Ii-MCB zincinci kwaye zinokufakwa lula kwiibhodi zokusasaza.

2. I-Residual Current Breaker (RCCB): Ezi zixhobo, ezikwaziwa ngokuba zii-RCD, zenzelwe ukuthintela ukutshayiswa kombane ngokufumanisa ukungalingani kwamandla ombane. Ukuba kufunyenwe impazamo, i-RCCB iya kukhubeka, inqumle umbane.

3. I-Leakage Current Circuit Breaker (ELCB): Njenge-RCCB, i-ELCB isetyenziselwa ukubona iimpazamo zomhlaba kunye nokuthintela ukutshayiswa ngumbane. Zibaluleke kakhulu kwiindawo ezimanzi, njengezindlu zangasese kunye neendawo zangaphandle.

4. Ii-Air Circuit Breakers (ACB): Ezi circuit breakers zisetyenziswa kwizicelo zoshishino kwaye zinokuphatha amazinga aphezulu ombane. Ii-ACB zenzelwe ukukhusela iinkqubo ezinkulu zombane kwaye zinokusetyenziswa ngesandla okanye ngokuzenzekelayo.

5. IiHydraulic Magnetic Circuit Breakers: Ezi circuit breakers zisebenzisa indibaniselwano yeendlela zobushushu kunye nemagnethi ukuvula icircuit. Zihlala zisetyenziswa kwiinkqubo zombane ezinkulu apho kukho khona imisinga ephezulu.

Ukubaluleka kwee-Circuit Breakers kwiiNkqubo zoMbane

Ukubaluleka kwee-circuit breakers akunakugxininiswa kakhulu. Zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kweenkqubo zombane. Ngokuthintela ukuxinana kakhulu kunye nee-short circuits, ii-circuit breakers azincedi nje ekukhuseleni izixhobo zombane, kodwa zikwanceda ekukhuseleni ubomi babantu abanokuba sesichengeni seengozi zombane.

Ukongeza kukhuseleko, ii-circuit breakers zikwanceda ekuphuculeni ukusebenza kakuhle kweenkqubo zombane. Ngokuqhawula ngokukhawuleza ii-circuit breakers, ii-circuit breakers zinokunciphisa ixesha lokungasebenzi kwaye zinciphise umngcipheko womonakalo omkhulu kwiziseko zombane. Oku kubaluleke kakhulu kwiindawo zorhwebo nezoshishino, apho umbane ongaphazanyiswayo ubaluleke kakhulu kwimisebenzi.

Isishwankathelo

Ngamafutshane, ii-circuit breakers ziyinxalenye ebalulekileyo yeenkqubo zombane zanamhlanje. Ukukwazi kwazo ukuphazamisa ukuhamba kombane ngokuzenzekelayo xa kukho impazamo kubalulekile ekukhuseleni abantu kunye nepropathi. Kukho iintlobo ezininzi ezahlukeneyo zee-circuit breakers, ezifanelekileyo kwizicelo ezahlukeneyo, ngoko ke ukuqonda umsebenzi wazo kunye nokubaluleka kwazo kubalulekile kuye nabani na obandakanyeka kubunjineli bombane okanye kukhuseleko. Njengoko iteknoloji iqhubeka ihambela phambili, ii-circuit breakers ngokuqinisekileyo ziya kuqhubeka zitshintsha, ziphucula ngakumbi indima yazo ekukhuseleni iinkqubo zethu zombane.
