Izinyathelo Zokuqapha Uma Usebenzisa I-RCBO

I-Residual current breaker (RCBO) enomsebenzi wokuvikela i-overcurrent iyisici esibalulekile ukuqinisekisa ukuphepha kwezinhlelo noma imishini enama-voltage aphansi. Ayikwazi nje ukuvimbela izingozi zokushaqeka kukagesi nokuvikela ukuphepha komuntu siqu, kodwa futhi iqaphe isimo sokufakwa kokushisa komhlabathi. Kodwa-ke, kubalulekile ukuqonda ukuthi ukufaka i-RCBO akuqinisekisi ukuphepha okungenakugwenywa. Kumelwe sigxile ekuvimbeleni futhi sisebenzise izinyathelo zobuchwepheshe ezahlukene zokuphepha ukuze sifinyelele ukusetshenziswa kukagesi okuphephile. I-RCBO iyisivikelo esengeziwe phakathi kwezinyathelo eziyisisekelo zokuvikela. Ukuphathwa ngokucophelela kanye nokumemezela kanye nemfundo ngokusetshenziswa kukagesi okuphephile kuyisiqinisekiso esiyisisekelo sokuphepha.

Into eyodwa okufanele uyikhumbule lapho usebenzisa i-RCBO ukuthi ingavikela umzimba womuntu kuphela uma kwenzeka ingozi yokushaqeka kagesi yesigaba esisodwa. Uma umzimba womuntu uvikelwe emhlabeni futhi uthintana nemigqa emibili yesigaba noma umugqa owodwa wesigaba kanye nomugqa owodwa ongathathi hlangothi, i-RCBO ngeke isebenze. Lokhu kusho ukuthi ngeke ihlinzeke ngesivikelo kulesi simo. Ngakho-ke, abasebenzisi kufanele baqaphele lo mkhawulo futhi bathathe izinyathelo ezengeziwe zokunciphisa ingozi yezingozi ezinjalo.

Esinye isinyathelo okufanele usicabangele ukuvikela isifunda ngemuva kwendawo yokufaka i-RCBO. Kubalulekile ukuthi isifunda sivikeleke kahle kusukela emhlabathini. Uma ukuvikela inhlabathi kuncishisiwe futhi ukuvuza komsinga kudlula inani elithile, ngokuvamile cishe i-15mA, i-RCBO izosebenza futhi inqamule ukunikezwa kwamandla. Lokhu kugcizelela ukubaluleka kokugcina ukuvikela okuhle kusukela emhlabathini ukuze kuvinjelwe amaphutha nokuqinisekisa ukusetshenziswa kwamandla okufanele. Ukuvikela kufanele kuhlolwe futhi kugcinwe njalo ukuze kugwenywe noma yiziphi izingozi ezingaba khona.

Uma igridi yamandla ene-voltage ephansi isebenzisa ukuvikelwa okuhlelekile, kubalulekile ukusebenzisa i-RCBO ebambezelekile ukuvikela ezingeni eliphezulu. Isikhathi sokuphuka kohlobo lwe-RCBO lokubambezeleka kufanele sibe side kunesikhathi sokusebenza kwesivikelo sezinga eliphansi, ngokuvamile imizuzwana engu-0.1 kuya ku-0.2. Lesi sinyathelo sokuqapha siqinisekisa indlela ephelele nehlelekile yokuvikela ngaphakathi kwegridi. Ngokulandela lesi siqondiso, unganciphisa izingozi ezingaba khona kanye nezingozi futhi uthuthukise ukuphepha okuphelele kohlelo lwakho lukagesi.

Ngamafuphi, yize ama-RCBO ebalulekile ekuvikeleni ukuphepha komuntu siqu kanye nokuqapha ukufakwa komoya phansi ezinhlelweni noma emishinini ene-voltage ephansi, kubalulekile futhi ukuqonda ukulinganiselwa kwawo futhi athathe izinyathelo zokuphepha ezidingekayo. Abasebenzisi kufanele bagxile ekuvimbeleni futhi basebenzise izinyathelo zobuchwepheshe ezahlukene zokuphepha ukuqinisekisa ukusetshenziswa kukagesi okuphephile. Kuphela ngokuphatha ngokucophelela ukusetshenziswa kukagesi, ukugcina ukufakwa komoya okuhle, kanye nokusebenzisa izinyathelo zokuvikela ezilinganisiwe lapho singafinyelela khona isiqinisekiso esiyisisekelo sokusetshenziswa kukagesi okuphephile.
