Yini i-rcbo futhi isebenza kanjani?

RboIngabe isifinyezo se- "Overculvent Residial Precial Breaker yamanje" futhi iyithuluzi elibalulekile lokuphepha kagesi elihlanganisa imisebenzi ye-MCB (Breaker Circuiture) ne-RCD (idivaysi yamanje). Inikeza ukuvikela ezinhlotsheni ezimbili zamaphutha kagesi: I-Overcurent and Residual yamanje (ebizwa nangokuthi i-Yavuage yamanje).

Ukuqonda kanjaniRboIsebenza, ake siqale sibuyekeze ngokushesha lezi zinhlobo ezimbili zokwehluleka.

Ukweqiwa kwenzeka lapho kugeleza okuningi kwamanje esisekelweni, esingadala ngokweqile futhi mhlawumbe nomlilo. Lokhu kungenzeka ngezizathu ezahlukahlukene, njengokujikeleza okufushane, ukugcwaliswa okugcwele kakhulu, noma iphutha likagesi. I-MCBS yenzelwe ukuthola nokuphazamisa la maphutha aphezulu ngokususa umjikelezo ngokushesha lapho okwamanje kudlula umkhawulo onqunyelwe.

Ngakolunye uhlangothi, isikhathi esisele samanje noma ukuvuza kwenzeka lapho umjikelezo uphazanyiswa ngengozi ngenxa ye-wiring empofu noma ngengozi ye-DIY. Isibonelo, kungenzeka ngenze ngengozi ngentambo ngenkathi ufaka i-hook yesithombe noma usike nge-lawnmower. Kulokhu, kungenzeka ukuthi kungenzeka kube namandla kagesi kungavuza imvelo ezungezile, kube nokubangela ukushaqeka kukagesi noma umlilo. Ama-RCD, abizwa nangokuthi i-GFCIS (i-Ground Fault Palcuit Aricturers) Kwamanye amazwe, aklanyelwe ukuthola ngokushesha imizamo yokuvuza ngisho nokuthatha umjikelezo wokuvuza ngaphansi kwemizuzu futhi ahambe nomjikelezo ngaphakathi kwama-milliseconds ukuvimba noma yikuphi ukulimala.

Manje, ake sibhekisise ukuthi i-RCBO ihlanganisa kanjani amakhono e-MCB ne-RCD. I-RCBO, njenge-MCB, ifakiwe ku-switchboard noma kwiyunithi yabathengi. Inemodyuli eyakhelwe ngaphakathi ye-RCD eqhubeka ngokubheka okugelezele kwamanje ngesifunda.

Lapho kwenzeka iphutha elingaphezulu, ingxenye ye-MCB ye-RCBO ithola isifunda ngokweqile futhi ilandele umjikelezo, ngaleyo ndlela iphazamisa noma iyiphi ingozi ehlobene nokulayisha ngokweqile noma umjikelezo omfushane. Ngasikhathi sinye, imodyuli eyakhelwe ngaphakathi ye-RCD iqapha ibhalansi yamanje phakathi kwezintambo ezibukhoma nezingathathi hlangothi.

Uma noma imuphi wamanje oseleyo etholwa (ekhombisa iphutha lokuvuza), i-RCBO's RCD element ngokushesha ihambela umjikelezo, ngaleyondlela inqamula ukunikezwa kwamandla. Lokhu kuphendula okusheshayo kuqinisekisa ukuthi ukushaqeka kukagesi kuyagwenywa futhi imililo engaba khona ivikelekile, yehlisa ubungozi bamaphutha we-wiring noma ukulimala kwekhebula ngengozi.

Kuhle ukuqaphela ukuthi i-RCBO ihlinzeka ngokuvikelwa kwesifunda ngasinye, okusho ukuthi ivikela amasekethe athile esakhiweni esizimele komunye nomunye, njengezindawo zokukhanyisa noma izitolo. Lokhu kuvikelwa okuvumelanayo kwenza ukutholwa kwephutha okuqondiswe kuyo nokuzihlukanisa, ukunciphisa umthelela kwamanye amasekethe lapho kwenzeka iphutha.

Ukufingqa, i-RCBO (i-Overculvent Residual Precial Breaker yamanje) iyithuluzi elibalulekile lokuphepha kagesi elihlanganisa imisebenzi ye-MCB ne-RCD. Inephutha elingaphezu kwamanje nemisebenzi yokuvikela yamanje yamanje yokuqinisekisa ukuphepha komuntu siqu futhi uvikele izingozi zomlilo. I-RCBOS idlala indima ebalulekile ekugcineni ukuphepha kukagesi emakhaya, izakhiwo zezentengiso nasezindaweni zezimboni ngokusheshe kutholwe imibuthano lapho kutholwa noma yiliphi iphutha.
