Izimo zokusetshenziswa kwe-RCCB

Izimo zokusetshenziswa kwama-residual current circuit breakers (RCCB) zibalulekile ekuqinisekiseni ukuphepha kwabantu nempahla. Ngaphambi kokuhlola izimo ezithile zokusetshenziswa, kubalulekile ukuqonda izimiso eziyisisekelo zokushaqeka kukagesi kanye nendima ye-RCCB ekuvimbeleni ukushaqeka kukagesi.

Ukushaqeka kukagesi ukulimala okukhulu okubangelwa ukudlula kogesi emzimbeni womuntu. Lapho izandla zomuntu zithinta ucingo oluphilayo, ugesi ungageleza emzimbeni, okubangela ukulimala okungenzeka. Ngemva kokushaqeka kukagesi, ugesi kumele unqanyulwe ngokushesha okukhulu. Umkhawulo wesikhathi sokunqamula ugesi uncike enanini logesi ogeleza emzimbeni. Isibonelo, uma ugesi ungama-50mA, isikhathi sokunqamula kufanele sibe ngaphakathi komzuzwana owodwa. Uma ugesi ungama-500mA, isikhathi sokunqamula sifinyezwa sibe yimizuzwana engu-0.1.

A I-Residual Current Breaker (I-RCCB) iyithuluzi lokuphepha likagesi elenzelwe ukunqamula ngokuzenzakalelayo ukunikezwa kwamandla uma kwenzeka ukuvuza kwamandla noma ukushaqeka kukagesi. Lapho ugesi ufinyelela inani lamandla okusebenza elibekwe yiswishi yokuvikela, i-RCCB inqamula ukunikezwa kwamandla kungakapheli isikhathi esinqunyiwe ukuqinisekisa ukuphepha kwabantu nempahla. Lokhu kwenza i-RCCB ibe yingxenye ebalulekile yokuphepha kukagesi ezimweni ezahlukahlukene zokusetshenziswa.

Izimo zokusetshenziswa kwe-RCCB ziyahlukahluka futhi zihlanganisa ububanzi obubanzi. Esinye sezimo eziyinhloko sihilela imigqa yokusabalalisa imishini kagesi ephathwayo nehambayo, kanye nemishini ezinzile lapho abantu bengase bangakwazi ukuphuma khona ngesikhathi uma kwenzeka ugesi ucinywa. Ngaphezu kwalokho, imishini kagesi ezindaweni zokusebenza zangaphandle kanye nezifunda zemishini yasekhaya noma izifunda zesokhethi kufanele ifakwe ama-RCCB anenani lamanje lokusebenza elilinganiselwe elingadluli ku-30mA. Lokhu kuqinisekisa ukuthi abantu bavikelekile ezingozini zokushaqeka kukagesi ezingaba khona kulezi zindawo.

Esinye isimo esibalulekile sokusetshenziswa kwe-RCCB ukukhanya kwe-elevator shaft okusebenza nge-AC 220V. Kulesi simo, i-voltage kagesi efanelekile yokukhanyisa i-elevator shaft ingu-36V. Kodwa-ke, uma usebenzisa i-AC 220V, kufanele kufakwe i-RCCB ukuze kunikezwe isivikelo esengeziwe. Ngaphezu kwalokho, umthombo wokukhanya kufanele ufakwe isembozo esivikelayo ukuze kuncishiswe ingozi yokushaqeka kukagesi.

Ngamafuphi, izimo zokusetshenziswa kwama-residual current circuit breakers (RCCB) zibalulekile ekuvimbeleni ukushaqeka kukagesi nokuqinisekisa ukuphepha kwabantu nempahla. Kusukela emishinini kagesi ephathwayo neyeselula kuya kumasekethe emishini yasekhaya kanye nokukhanyisa kwe-elevator shaft, ama-RCCB adlala indima ebalulekile ekuvimbeleni imiphumela eyingozi yokushaqeka kukagesi. Ngokuqonda nokusebenzisa izimo zokusetshenziswa ezifanele ze-RCCB, abantu ngabanye kanye nezinhlangano bangakha indawo ephephile futhi banciphise ingozi yezingozi zikagesi.
