Ukusetshenziswa kweukuvalwa kwe-circuit breaker, obeye aziwe njengoamalokhi e-loto breaker, iyingxenye ebalulekile yokuqinisekisa ukuphepha kwezisebenzi kanye nokuvimbela izingozi zikagesi emsebenzini.Umaka wokukhiya ngaphandle (LOTO)Izinqubo ziqashelwa kabanzi njengendlela ephumelelayo yokuvikela abasebenzi emithonjeni yamandla eyingozi, futhi ukusebenzisa ukuvala ama-breaker lockout kuyisici esibalulekile sale nqubo.
Ukuvala ama-Circuit breakerzenzelwe ukuvimbela ngokoqobo ukusebenza ngengozi noma okungagunyaziwe kwamasekhethi kagesi noma okokusebenza.Ziza ngemiklamo nezitayela ezihlukahlukene ukuze zilingane nezinhlobo ezahlukene zama-circuit breaker, okuzenza zibe nezinto ezihlukahlukene futhi zivumelane nezimo ukuze zisetshenziswe kuzilungiselelo eziningi zezimboni.Lezi zixhobo zibalulekile ekusebenziseni izinqubo ze-LOTO, njengoba zinikeza indlela ebonakalayo nevikelekile yokuhlukanisa imithombo yamandla kanye nokuxwayisa abanye ngomsebenzi wokulungisa noma wokulungisa okuqhubekayo.
Enye yezinjongo eziyinhloko zokusebenzisaukuvalwa kwe-circuit breakerukuqinisekisa ukuthi impahla kagesi iphelelwa amandla ngaphambi kokuba kwenziwe noma iyiphi isevisi noma ukulungiswa.Ngokunamathisela idivayisi yokuvala i-breaker, okokusebenza kuhlukaniswa ngokuphumelelayo emthonjeni wamandla, futhi amandla okusebenza ngengozi ayasuswa.Lokhu kuvumela abasebenzi ukuba benze imisebenzi yabo ngaphandle kwengozi yokuchayeka emisinga kagesi ephilayo, kunciphisa kakhulu amathuba ezingozi nokulimala kukagesi.
Ngaphezu kwalokho, ukusetshenziswaukuvala ama-breakerfuthi idlala indima ebalulekile ekuhambisaneni nemithethonqubo namazinga okuphepha.Izikhungo eziningi ezilawulayo, njenge-OSHA e-United States, zidinga abaqashi ukuthi basebenzise izinqubo ze-LOTO ukuze bavikele abasebenzi babo emithonjeni yamandla eyingozi.Ukwehluleka ukulandela le mithetho kungaholela ezijezisweni futhi, okubaluleke nakakhulu, ingozi yezingozi ezimbi.Ngakho-ke, ukusetshenziswaukuvalwa kwe-circuit breakerakuyona nje inkambiso engcono kakhulu, kodwa iyisidingo esingokomthetho ezindaweni eziningi zokusebenza.
Ngaphezu kwalokho, ukufakwa kwe-ukuvala ama-breakerezinqubweni ze-LOTO ikhuthaza isiko lokuphepha nokuzibophezela ngaphakathi kwenhlangano.Lapho izisebenzi zibona ukuthi izinyathelo zokuphepha ezidingekayo, njengokusebenzisa izinto zokukhiya, ziyathathwa ukuze zivikeleke ekulimaleni okungase kube khona, kuqinisa umyalezo wokuthi inhlalakahle yazo ibalulekile.Lokhu kungaholela ekwandiseni ukuqwashisa ngezinqubo zokuphepha kanye nendlela esheshayo yokugwema izingozi emsebenzini.
Kuyaphawuleka ukuthi ukuqeqeshwa okufanele kanye nemfundo mayelana nokusetshenziswaukuvalwa kwe-circuit breakerzibalulekile ukuze zisetshenziswe ngempumelelo.Abasebenzi kufanele bajwayelane nezinhlobo ezahlukene zemishini yokukhiya futhi baqonde ukuthi isetshenziswa kanjani ngendlela efanele kuma-circuit breaker ahlukahlukene.Ukwengeza, izinqubo ezicacile nezijwayelekile zokuthi umaka wokukhiya ngaphandle kufanele zisungulwe futhi zidluliselwe kubo bonke abasebenzi abahililekile emisebenzini yokulungisa noma yokulungisa.
Ekugcineni, ukusetshenziswa kweukuvalwa kwe-circuit breakerkuyisici esibalulekile ekuqinisekiseni ukuphepha kwabasebenzi kanye nokuvimbela izingozi zikagesi emsebenzini.Ngokuhlanganisa le mishini ezinqubweni ze-LOTO, abaqashi bangakwazi ukuhlukanisa imithombo yamandla kagesi futhi bavikele abasebenzi ezingozini ezingaba khona.Ngaphezu kwalokho, ukusebenzisaukuvala ama-breakeribonisa ukuzibophezela ekuhambisaneni nemithetho yezokuphepha futhi ikhuthaza isiko lokuphepha ngaphakathi kwenhlangano.Ukutshala imali ekuqeqeshweni okufanele nasekusetshenzisweni kokuvala ama-circuit breaker kuyisinyathelo esisheshayo esinganciphisa kakhulu ubungozi bezigameko zikagesi futhi sibe nomthelela endaweni ephephile yokusebenza.
