Amaphuzu ama-4 okudingeka uwaqaphele uma usebenzisa i-RCBO

Uma kukhulunywa ngokuphepha kukagesi, ukubaluleka kokusebenzisa i-I-RCBO (I-Residual Current Breaker ene-Overcurrent Protection) ayinakukhushulwa ngokweqile. Lo mshini obalulekile wenzelwe ukuvikela abasebenzi ekushayweni ugesi uma kwenzeka ukuvuza kwemishini kwehluleka, ukuqinisekisa ukuphepha komuntu siqu ezindaweni zokuhlala nezentengiselwano. Njengoba inezici zokuvikela ukugcwala ngokweqile kanye nesekhethi esifushane, ama-RCBO ayizingxenye ezibalulekile kunoma yiluphi uhlelo lukagesi. Kodwa-ke, kunamaphuzu amaningana abalulekile okufanele uwakhumbule lapho usebenzisa i-RCBO ukuqinisekisa ukusebenza kwayo okuhle kanye nokusebenza kahle.

Okokuqala, kubalulekile ukunaka inani lamanje lokusebenza elisele elilinganisiwe le-RCBO. Uma kufakwa isivikelo sokusebenza samanje esisele phakathi kwesivikelo esijwayelekile nesivikelo sokugcina, inani lamanje lokusebenza elisele elilinganisiwe kufanele libe ngaphakathi kobubanzi bezivikelo zokusebenza zamanje ezisele ezingeni eliphezulu neliphansi. Umehluko wesinyathelo ngokuvamile kufanele ube phakathi kwezikhathi eziyi-1.2 nezingu-2.5 ukuqinisekisa ukusebenza kahle nangokushelela kwe-RCBO ngaphakathi kohlelo lukagesi.

Ngaphezu kwenani lamanje lokusebenza elisele elilinganisiwe, kubalulekile futhi ukucabangela inani lamanje lokusebenza elisele elilinganisiwe eliphezulu lokuvikelwa okuphelele. Ngesizini engeyona yemvula, inani lamanje lokusebenza elisele elilinganisiwe eliphezulu akufanele lidlule ku-75-100mA, kanti ngenkathi yemvula, akufanele lidlule ku-200-300mA. Ngezicelo zasekhaya, inani lamanje lokusebenza lesivikelo sokusebenza samanje esisele akufanele libe ngaphezu kuka-30mA ukuze linikeze isivikelo sokuxhumana ngqo kubantu ngabanye. Ngaphezu kwalokho, lapho i-RCBO isetshenziselwa imishini yamandla eselula kanye nemishini yamandla yesikhashana, inani layo lamanje lokusebenza kufanele libe ngu-30mA.

Elinye iphuzu elibalulekile okufanele ulicabangele lapho usebenzisa i-RCBO ukufakwa okufanele kanye nokufakwa kwesisekelo semishini. Ukuze kuvikelwe ngokujwayelekile amagridi kagesi aphansi, iphuzu elingathathi hlangothi le-transformer kufanele lixhunywe ngqo emhlabathini. Kubalulekile ukuqinisekisa ukuthi i-grid neutral conductor ayigxilile kabili futhi igcina izinga elifanayo lokufakwa kwe-insulation njenge-phase conductors. Ngaphezu kwalokho, indlela yokufaka ye-residual current action protector kufanele ivimbele umugqa ongathathi hlangothi kanye nomugqa wesigaba ukuthi ungahlanganyelwani nezinye izifunda ukuqinisekisa ukusebenza okuvamile kwe-RCBO.

Okokugcina, ukusatshalaliswa komthwalo kagesi kufanele kucatshangelwe ngokucophelela lapho kusetshenziswa i-RCBO, ikakhulukazi imithwalo yesigaba esisodwa. Kubalulekile ukusabalalisa ngokulinganayo ukukhanya kanye neminye imithwalo kagesi yesigaba esisodwa emigqeni kagesi yesigaba ezintathu. Uma ukuphambuka kukhulu, kufanele kwenziwe ukulungiswa ukuze kwenziwe imisinga yokuvuza yesigaba ngasinye ilingane ukuqinisekisa ukusebenza okuhle kakhulu kwe-RCBO. Ngaphezu kwalokho, lapho imigqa ye-voltage ephansi iyimigqa yezwe, izigaba ezintathu kufanele zibe nobude obufanayo ukuze kuhlinzekwe ukusatshalaliswa okulinganiselayo komthwalo kagesi.

Ngamafuphi, ukusetshenziswa kahle kwama-RCBO kubalulekile ekuphepheni nasekuvikelweni kukagesi. Ngokunaka inani lamanje lokusebenza elisele elilinganisiwe, amandla okusebenza asele alinganisiwe aphezulu, ukufakwa kanye nokufakwa phansi, kanye nokusatshalaliswa kwemithwalo kagesi, abantu bangaqinisekisa ukusebenza kahle kwe-RCBO ohlelweni lwabo lukagesi. Njengoba benekhono lokuvikela ekushayweni kukagesi kanye nokwehluleka kwemishini, ama-RCBO ayisici esibalulekile ekugcineni ingqalasizinda kagesi ephephile nethembekile.
