Ama-circuit Breaker: Amaqhawe Angadumile Okuphepha Kukagesi
Ezweni lezinhlelo zikagesi, ama-circuit breaker adlala indima ebalulekile ekuqinisekiseni ukuphepha nokusebenza kokufakwa konke. Kuyidivayisi elula kodwa ehlakaniphile eyenzelwe ukuvikela ama-circuit emonakalweni obangelwa yi-overcurrent kanye nama-short circuit. Ama-circuit breaker asebenza njengendlela ephephile yokwehluleka, ephazamisa ukuhamba kukagesi lapho kutholwa izimo ezingavamile, ngaleyo ndlela evimbela izingozi ezingaba khona njengemililo kagesi kanye nomonakalo wemishini.
Isimiso esiyisisekelo se-circuit breaker ukuvula i-circuit ngokuzenzakalelayo lapho ugesi udlula umkhawulo othile. Lokhu kufezwa ngendlela esebenzisa i-bimetallic strip noma i-electromagnet ukuze iphazamise i-circuit breaker lapho kutholakala ugesi ongaphezulu. Uma i-circuit isiphazanyisiwe, i-circuit breaker ingasethwa kabusha ngesandla ukuze kubuyiselwe ukugeleza, okwenza kube yidivayisi yokuphepha engasetshenziswa kabusha.
Kunezinhlobo ezahlukene zama-circuit breaker aklanyelwe izinhlelo zokusebenza ezahlukahlukene, okuhlanganisa izindawo zokuhlala, zezentengiselwano, kanye nezezimboni. Ezakhiweni zokuhlala, ama-miniature circuit breaker (ama-MCB) avame ukusetshenziswa ukuvikela ama-circuit ngamanye, njengalawo okukhanyisa, izinto zikagesi, kanye nama-socket. Lawa ma-MCB ancane futhi angafakwa kalula kumaphaneli kagesi, ahlinzeka ngendlela elula nephumelelayo yokuvikela uhlelo lukagesi lwekhaya.
Ezindaweni zezentengiselwano nezezimboni, ama-circuit breaker amakhulu njenge-molded case circuit breaker (MCCB) kanye nama-air circuit breaker (ACB) asetshenziselwa ukuvikela ama-voltage aphezulu kanye nama-current circuit. Njengoba ekwazi ukusingatha imithwalo kagesi emikhulu, la ma-circuit breaker anzima abalulekile ekuqinisekiseni ukuphepha nokuthembeka kwezinhlelo zikagesi eziyinkimbinkimbi ezakhiweni zezentengiselwano, ezimbonini nasezitshalweni zikagesi.
Enye yezinzuzo eziyinhloko zama-circuit breaker yikhono lawo lokuphendula ngokushesha nangokunembile ezimweni zomsinga odlulayo, ngaleyo ndlela anciphise ingozi yezingozi zikagesi. Ngokungafani nama-fuse, adinga ukushintshwa ngemva kokusebenza, ama-circuit breaker angasethwa kabusha, okwenza abe yisisombululo esilula nesingabizi kakhulu sokuvikela ama-circuit.
Ngaphezu komsebenzi wazo oyinhloko wokuvikela ugesi ngokweqile, ama-circuit breaker anamuhla anikeza izici ezithuthukisiwe njengokuvikela amaphutha omhlaba, ukutholwa kwamaphutha e-arc, kanye namakhono okuqapha akude. Lezi zici ezengeziwe zithuthukisa ukuphepha nokusebenza kwezinhlelo zikagesi, okwenza ama-circuit breaker abe yingxenye ebalulekile yengqalasizinda kagesi yesimanje.
Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukuthuthukiswa kwama-smart circuit breaker nakho kuyakhula ngamandla. Ama-smart circuit breaker afakwe izinzwa ezakhelwe ngaphakathi kanye namakhono okuxhumana awenza akwazi ukunikeza idatha yesikhathi sangempela ngamapharamitha kagesi kanye nesimo sesistimu. Lokhu kwenza ukulungiswa okusheshayo kanye nokuxazulula izinkinga kude, okwandisa ukuthembeka kanye nokusebenza kahle kokufakwa kukagesi.
Sekukonke, ama-circuit breaker angase angatholi ukunakwa njalo, kodwa ngokungangabazeki ayisici esibalulekile ekuqinisekiseni uhlelo lukagesi oluphephile noluthembekile. Kusukela emakhaya kuya ezindaweni zezimboni, ama-circuit breaker adlala indima ebalulekile ekuvimbeleni izingozi zikagesi nokugcina ubuqotho bengqalasizinda kagesi. Njengoba isidingo sezixazululo zikagesi ezisebenzisa amandla kahle nezihlakaniphile siqhubeka nokukhula, ukubaluleka kwama-circuit breaker ekuvikeleni izinhlelo zikagesi kuzobonakala kakhulu eminyakeni ezayo.
