kuyini ukukhiya kwe-circuit breaker

Aidivayisi yokukhiya i-circuit breakeriyithuluzi lokuphepha elisetshenziselwa ukuvimbela ukunikezwa kwamandla ngengozi kwesekethe ngesikhathi sokulungisa noma sokulungisa. Liyingxenye ebalulekile yezinqubo zokuphepha kagesi ezindaweni zezimboni, zezentengiselwano nezindawo zokuhlala. Inhloso ye-ukukhiya kwe-circuit breakerukuqinisekisa ukuthi imishini kagesi ihlala ingasebenzi kahle ngesikhathi kulungiswa noma kulungiswa, ngaleyo ndlela kuvikelwe abasebenzi engcupheni yokushaqeka ngogesi noma ezinye izingozi zikagesi.

Idivayisi yokukhiya ngaphandle ivame ukuba yithuluzi elincane, eliphathekayo elingaxhunywa kalula ku-circuit breaker ukuze livinjwe ukuthi lingavuleki. Lenzelwe ukufakwa ngokuphephile kuswishi ye-circuit breaker, livinjwe ukuthi lisebenze. Lokhu kukhiya ngempumelelo i-circuit breaker endaweni engasebenzi, kuqinisekiswe ukuthi i-circuit ihlala ingasebenzi kuze kube yilapho idivayisi yokukhiya isusiwe.

Kunezinhlobo eziningana ze-ukukhiya ngaphandle kwe-circuit breakeretholakalayo, ngayinye yenzelwe uhlobo oluthile lwe-circuit breaker kanye nemishini kagesi. Amanye amadivayisi okukhiya aklanyelwe ukufakwa ku-toggle noma i-rocker switch ejwayelekile ye-circuit breaker, kuyilapho amanye amadivayisi okukhiya aklanyelwe ukusetshenziswa nama-molded case circuit breaker noma eminye imishini kagesi ekhethekile. Ngaphezu kwalokho, kunemishini yokukhiya evumela ama-circuit breaker amaningi, okuvumela ama-circuit amaningi ukuthi avalelwe ngaphandle ngesikhathi esisodwa.

Inqubo yokusebenzisa i-ukukhiya kwe-circuit breakerkuhilela izinyathelo eziningana ezibalulekile ukuqinisekisa ukusetshenziswa okufanele. Okokuqala, abasebenzi abagunyaziwe kumele bathole i-circuit breaker ethile okudingeka ivalwe. Uma i-circuit breaker isitholakala, idivayisi ekhiyayo ixhunywe ngokuphephile ku-switch, okuyivimbela ukuthi ivuleke ngempumelelo. Kubalulekile ukuqinisekisa ukuthi idivayisi ekhiyayo ifakwe kahle futhi ayikwazi ukususwa noma ukuphazanyiswa kalula.

Ngaphezu kwamadivayisi okukhiya ngaphandle ngokomzimba,ukukhiya/ukuphumaizinqubo kumele zisetshenziswe ukunikeza isibonakaliso esicacile esibonakalayo sokuthi i-circuit breaker ikhiyiwe futhi akufanele inikwe amandla. Lokhu ngokuvamile kuhilela ukunamathisela ithegi yokukhiya kudivayisi ekhiyiwe ekhombisa isizathu sokukhiya, usuku nesikhathi sokukhiya, kanye negama lomuntu ogunyaziwe owenze ukukhiya. Lokhu kusiza ukwazisa abanye abasebenzi ngesimo se-circuit breaker ekhiyiwe futhi kuvimbela imizamo engagunyaziwe yokunika amandla i-circuit.

Ukusetshenziswa kweukukhiya ngaphandle kwe-circuit breakerilawulwa yimithethonqubo nezindinganiso zokuphepha, njengalezo ezibekwe yi-US Occupational Safety and Health Administration (OSHA). Le mithethonqubo idinga abaqashi ukuthi basebenzise izinqubo zokukhiya/zokumisa abasebenzi ukuze bavikele abasebenzi ekusebenzeni ngengozi kwemishini noma imishini ngesikhathi sokulungiswa noma ukulungiswa. Ukwehluleka ukulandela le mithethonqubo kungabangela izinhlawulo ezinkulu kanye nezinhlawulo kubaqashi.

Ekuphetheni,ukukhiya kwe-circuit breakerkuyisinyathelo esibalulekile sokuphepha esisiza ukuvikela abasebenzi ezingozini zikagesi ngesikhathi sokulungisa nokulungisa. Ngokuvala ngempumelelo amasekethe, la madivayisi avimbela ukunikezwa kwamandla ngengozi futhi anciphise ingozi yokushaqeka kukagesi kanye nokunye ukulimala. Abaqashi nabasebenzi kumele baqaphele ukubaluleka kokusebenzisa amadivayisi okukhiya i-circuit breaker ngokuhambisana nemithetho yokuphepha ukuqinisekisa indawo yokusebenza ephephile.
