Uma kukhulunywa ngokuphepha kukagesi,amadivayisi okukhiya ngaphandle kwe-circuit breakerziyithuluzi elibalulekile lokuvimbela ukuvuselelwa kwamandla ngengozi. Lawa madivayisi aklanyelwe ukukhiya ngokuphephile i-circuit breaker endaweni engasebenzi, ukuqinisekisa ukuthi ayikwazi ukuvulwa ngenkathi kwenziwa umsebenzi wokulungisa. Uhlobo olulodwa lwedivayisi yokukhiya i-circuit breaker evame ukusetshenziswa ezimweni zezimboni nezentengiselwano i-breaker lockout enkulu kakhulu.
Ukukhiya kwe-breaker enkulu kakhulu uhlobo lwedivayisi yokukhiya eklanyelwe ngqo ukulingana kuma-circuit breaker amakhulu anama-toggles amakhulu noma angakheki ngendlela engavamile. Lawa ma-breaker amakhulu avame ukutholakala emishinini esindayo, emishinini yezimboni, kanye nasezinhlelweni zikagesi ezinkulu. Ngokungafani namadivayisi ajwayelekile okukhiya kwe-breaker, angase angalingani ngokuphephile kuma-breaker amakhulu, i-ukukhiya kwe-breaker okukhulu kakhuluinikeza ukulingana okuqinile nokuphephile, okuqinisekisa ukuthi i-breaker ayikwazi ukuphazanyiswa noma ivulwe ngengozi.
Umklamo we-ukukhiya kwe-breaker okukhulu kakhulungokuvamile inesivalo esiqinile, esibonakala kakhulu esingabonakala kalula ngabasebenzi bokulungisa. Isivalo sifakwe indlela yokukhiya engavikelwa ngengidi, okuvimbela ukufinyelela okungagunyaziwe ku-breaker. Idivayisi yokukhiya ifaka nendlela yokuguqula engalungiswa kalula ukuze ivumelane nosayizi abahlukene bama-breaker amakhulu, okwenza kube yisisombululo esiguquguqukayo nesisebenzayo sezinhlelo zokusebenza eziningi zezimboni nezentengiselwano.
Ukusebenzisa i-breaker lockout enkulu kakhulu kuyindlela elula nephumelelayo yokuthuthukisa ukuphepha kukagesi endaweni yokusebenza. Ngokuvala ngokuphephile ama-circuit breaker amakhulu kakhulu, izisebenzi zokulungisa zingaba nokuthula kwengqondo ngokwazi ukuthi imishini abasebenza kuyo ayinamandla futhi iphephile ukuyiphatha. Lokhu kusiza ukuvimbela izingozi, ukulimala, kanye nomonakalo emishinini, ekugcineni kube negalelo endaweni yokusebenza ephephile.
Ngaphezu kweukukhiya okukhulu kakhulu kwe-breaker, kunezinye izinhlobo zamadivayisi okukhiya ngaphandle kwesekethe atholakalayo, njenge-clamp-on breaker lockouts, i-snap-on breaker lockouts, kanye ne-tie bar lockouts. Uhlobo ngalunye lwedivayisi yokukhiya ngaphandle lwenzelwe ukulingana nezinhlobo ezithile zama-circuit breaker, futhi kubalulekile ukukhetha idivayisi yokukhiya efanele ye-breaker ethile esetshenziswayo.
Uma ukhethaidivayisi yokukhiya i-circuit breaker, kubalulekile ukucabangela usayizi nohlobo lwe-breaker, kanye nezidingo ezithile zomsebenzi wokulungisa owenziwayo. Kubalulekile futhi ukuqinisekisa ukuthi idivayisi yokukhiya iyahambisana nezingidi kanye neminye imishini yokuphepha esetshenziswa endaweni yokusebenza.
Ekuphetheni,amadivayisi okukhiya ngaphandle kwe-circuit breakeridlala indima ebalulekile ekuqinisekiseni ukuphepha kukagesi ezindaweni zezimboni nezentengiselwano. Ukusetshenziswa kwe-breakout enkulu kakhulu kunganikeza ungqimba olwengeziwe lokuphepha kwama-circuit breaker amakhulu, angakhekile ngendlela engavamile, okusiza ekuvimbeleni izingozi nokulimala ngesikhathi somsebenzi wokulungisa. Ngokutshala imali kumadivayisi okukhiya asezingeni eliphezulu kanye nokunikeza ukuqeqeshwa okuphelele kokuphepha kwabasebenzi, amabhizinisi anganciphisa ingozi yezingozi zikagesi futhi adale indawo yokusebenza ephephile kuwo wonke umuntu.
