Amadivayisi okukhiya ngaphandle kwe-circuit breaker, obeye aziwe njengoIzikhiye zokuphepha ze-MCBnoma ama-circuit breaker okukhiya, amathuluzi abalulekile asetshenziswa ukwandisa ukuphepha kokusebenza ezinhlelweni zikagesi. Le divayisi yenzelwe ukuvimbela ukusebenza ngengozi noma okungagunyaziwe kwama-circuit breaker, ukuqinisekisa ukuthi abasebenzi bangasebenza kuma-circuit noma imishini ngaphandle kokulimala.
Inhloso eyinhloko ye-idivayisi yokukhiya i-circuit breakerukuhlukanisa isekethe kagesi ngesikhathi sokulungisa, ukulungisa noma ukufaka. Isebenza njengesivikelo esibonakalayo, ivala i-circuit breaker endaweni engaphandle, iqinisekisa ukuthi i-circuit breaker ayikwazi ukuvulwa ngengozi. Lokhu kubaluleke kakhulu lapho abasebenzi kudingeka benze imisebenzi ezindaweni zikagesi ezingaba yingozi.
Esinye sezici eziyinhloko ze-ukukhiya kwe-circuit breakerkulula ukuyisebenzisa. Ngokuvamile iyithuluzi elilula nelilula elingafakwa kalula kwi-circuit breaker. Amadivayisi amaningi okukhiya aqukethe indlu yepulasitiki eqinile efaka iswishi noma iswishi ye-circuit breaker ukuze ivinjwe ukuthi ingasebenzi. Aklanyelwe ukulungiswa kalula ukuze alingane nosayizi abahlukahlukene be-circuit breaker futhi angavikelwa kalula nge-padlock noma i-hasp ukuze kuvikelwe okwengeziwe.
Kunezici eziningana okufanele uzicabangele lapho ukhethaidivayisi yokukhiya i-circuit breakerOkokuqala, kubalulekile ukuqinisekisa ukuthi idivayisi iyahambisana nohlobo oluthile kanye nemodeli ye-circuit breaker esetshenziswayo. Ama-circuit breaker angahluka ngomklamo kanye nosayizi kusukela kumkhiqizi kuya kumkhiqizi, ngakho-ke kubalulekile ukukhetha idivayisi yokukhiya efanelekile imishini yakho ethile. Okwesibili, idivayisi yokukhiya kufanele yenziwe ngezinto eziqinile nezingenawo ugesi ukuze kuvinjelwe noma yiziphi izingozi zikagesi. Kufanele imelane nokugqwala futhi ikwazi ukumelana namazinga aphezulu kagesi.
Izinzuzo zokusebenzisa i-idivayisi yokukhiya i-circuit breakerAkunakweqiswa. Nciphisa ingozi yokushaqeka kukagesi noma izingozi zikagesi ngokukhiya ngempumelelo i-circuit breaker, uvimbele ukuhamba kukagesi. Kunikeza isibonakaliso esicacile kunoma ubani oseduze sokuthi ukulungiswa noma ukulungiswa kuyaqhubeka, kugwema noma yikuphi ukungaqondani noma ukusebenza kwe-switch ngengozi.
Enye inzuzo yokusebenzisa amadivayisi okukhiya ukuthi anikeza izinga lomthwalo wemfanelo nokulawula. Njengoba i-circuit breaker ivaliwe ngempumelelo, abasebenzi abagunyaziwe kuphela abanekhono lokususa idivayisi yokukhiya abangaqalisa kabusha i-circuit. Lokhu kusiza ukuvimbela abantu abangagunyaziwe ukuthi bavule i-circuit breaker ngengozi noma ngamabomu.
Ekuphetheni, i-idivayisi yokukhiya i-circuit breakeriyithuluzi elibalulekile lokuphepha lapho usebenza ezinhlelweni zikagesi. Umsebenzi walo oyinhloko ukuvala i-circuit breaker endaweni engasebenzi, ukuvimbela noma yikuphi ukusebenza ngengozi noma okungagunyaziwe. Ngokusebenzisa le divayisi, ukuphepha endaweni yokusebenza kungathuthukiswa kakhulu futhi ingozi yezingozi zikagesi incishiswe. Ngakho-ke, ukusetshenziswa kwe-idivayisi yokukhiya i-circuit breakerKunconywa kakhulu lapho kwenziwa umsebenzi wokulungisa, ukulungisa, noma wokufaka kumasekethe kagesi noma imishini.
