Uma kuziwa ekuphepheni kukagesi,amadivaysi okuvala ama-circuit breakerzingamathuluzi abalulekile okuvimbela ukuvuselela amandla ngephutha.Lawa madivayisi aklanyelwe ukukhiya ngokuvikelekile i-circuit breaker lapho ivaliwe, iqinisekisa ukuthi ayikwazi ukuvulwa ngenkathi kwenziwa umsebenzi wokulungisa.Olunye uhlobo lwedivayisi yokuvala i-circuit breaker evame ukusetshenziswa ezilungiselelweni zezimboni nezohwebo ukuvala i-breaker lockout.
Ukuvala i-breaker lockout kuwuhlobo lwedivayisi yokukhiya edizayinelwe ngokuqondile ukuthi ilingane kuma-circuit breaker amakhulu anama-toggle anomumo omkhulu noma ongajwayelekile.Lezi zigebengu ezinkulu zivame ukutholakala emishinini esindayo, emishinini yezimboni, nasezinhlelweni zikagesi ezinkulu.Ngokungafani namadivayisi ajwayelekile wokuvala ama-breaker, angase angalingani ngokuvikelekile kuma-breaker amakhulu, anukuvala i-breaker lockoutinikeza ukulingana okuqinile nokuvikelekile, okuqinisekisa ukuthi isiphuli asikwazi ukuphazamiseka noma sivulwe ngephutha.
Umklamo we-ukuvala i-breaker lockoutngokuvamile ifaka i-casing eqinile, ebonakalayo ephezulu engabonakala kalula izisebenzi ezilungisayo.I-casing ifakwe indlela yokukhiya engavikelwa ngengidi, ukuvimbela ukufinyelela okungagunyaziwe ku-breaker.Idivayisi yokukhiya iphinde ihlanganise nendlela yokuguqula engalungiswa kalula ukuze ilingane osayizi abahlukene bamabhulabhula amakhulu, iyenze ibe yisixazululo esisebenza ngezindlela eziningi futhi esisebenzisekayo sohlu olubanzi lwezinhlelo zokusebenza zezimboni nezohwebo.
Ukusebenzisa i-oversized breaker lockout kuyindlela elula nephumelelayo yokuthuthukisa ukuphepha kukagesi emsebenzini.Ngokuvalela ngaphandle ama-circuit breaker amakhulu kakhulu, abasebenzi bezokulungisa bangaba nokuthula kwengqondo bazi ukuthi okokusebenza abasebenzela phezu kwabo kuphelelwe amandla futhi kuphephile ukukuphatha.Lokhu kusiza ukuvimbela izingozi, ukulimala, nokulimala kwemishini, ekugcineni kube nomthelela endaweni ephephile yokusebenza.
Ngaphezu kweukuvala ama-breaker amakhulu, kukhona nezinye izinhlobo zamadivayisi wokuvala ama-circuit breaker atholakalayo, afana nokuvala ama-clamp-on breaker, ukuvala ama-breaker snap-on, kanye nokukhiya ngaphandle kwama-tie bar.Uhlobo ngalunye lwedivayisi yokukhiya ludizayinelwe ukuthi lulingane nezinhlobo ezithile zama-circuit breaker, futhi kubalulekile ukukhetha idivayisi efanele yokuvala i-breaker ethile esetshenziswayo.
Lapho ukhetha i-aidivayisi yokuvala i-circuit breaker, kubalulekile ukucabangela usayizi nohlobo lwesiphuli, kanye nezidingo ezithile zomsebenzi wokulungisa owenziwayo.Kubalulekile futhi ukuqinisekisa ukuthi idivayisi yokukhiya iyahambisana nezingidi nezinye izinto zokuphepha ezisetshenziswa endaweni yokusebenza.
Ekuphetheni,amadivaysi okuvala ama-circuit breakeridlala indima ebalulekile ekuqinisekiseni ukuphepha kukagesi ezimbonini nasezindaweni zezohwebo.Ukusetshenziswa kokuvala i-breaker lockout okukhulu kakhulu kunganikeza isendlalelo esingeziwe sokuphepha kuma-circuit breaker amakhulu, anomumo ongajwayelekile, okusiza ukuvimbela izingozi nokulimala ngesikhathi somsebenzi wokulungisa.Ngokutshala kumadivayisi wokukhiya wekhwalithi ephezulu nokuhlinzeka ngokuqeqeshwa okuphelele kokuphepha kwabasebenzi, amabhizinisi anganciphisa ubungozi bezingozi zikagesi futhi adale indawo yokusebenza ephephile yawo wonke umuntu.
