Njengoba kushiwo ngaphambili, i-RCBO iqinisekisa ukuvikeleka ezinhlotsheni ezimbili zamaphutha kagesi.Elokuqala kulawa maphutha ukuvuza kwamanje noma umhlaba.Lokhu kuthandalkwenzeka uma kuba nokuphuka ngephutha kwesekhethi, okungase kwenzeke ngenxa yamaphutha ezintambo noma izingozi ze-DIY (njengokusika ngekhebula uma usebenzisa i-hedge cutter kagesi).Uma ukunikezwa kukagesi kungaphulwanga, khona-ke umuntu uzobhekana nokushaqeka kukagesi okungaba yingozi enkulu

Olunye uhlobo lwephutha likagesi i-overcurrent, engase ithathe isimo sokugcwala ngokweqile noma isifunda esifushane, Esikhathini sokuqala.Isekhethi izolayishwa kakhulu ngamadivaysi kagesi amaningi, okuholela ekudlulisweni kwamandla angaphezu kwamandla ekhebula.I-short-circuiting ingase futhi yenzeke ngenxa yokungangeni kwesekethe ukumelana nokuphindaphindeka kwe-high-eve ye-amperage.Lokhu kuhlotshaniswa nezinga elikhulu lengozi kunokulayisha ngokweqile

Bheka izinhlobo ze-RCBO ezitholakala kumabhrendi ahlukene ngezansi.

I-RCBO vs. MCB

I-MCB ayikwazi ukuvikela emaphutheni omhlaba, kuyilapho ama-RCBO akwazi ukuvikela ekushayweni kukagesi namaphutha omhlaba.

Ama-MCB aqapha ukugeleza kwamanje futhi aphazamise amasekhethi phakathi namasekhethi amafushane nokulayishwa ngokweqile.Ngokuphambene, ama-RCBO aqapha ukugeleza kwamanje emugqeni kanye nokugeleza kokubuyisela emugqeni ophakathi nendawo.Futhi, ama-RCBOs angaphazamisa ukujikeleza phakathi nokuvuza komhlaba, ukujikeleza okufushane, kanye nokudlula ngokweqile.

Ungasebenzisa ama-MCB ukuvikela ama-air conditioner, amasekhethi okukhanyisa, nezinye izinto ezisetshenziswayo ngaphandle kwamadivayisi namahitha athintana ngqo namanzi.Ngokuphambene, ungasebenzisa i-RCBO ukuze uvikeleke ekushayweni kukagesi.Ngakho-ke, ungayisebenzisa ukuphazamisa amandla, amasokhethi kagesi, izifudumezi zamanzi lapho ungase ube nethuba lokushaqeka kukagesi.

Ungakhetha ama-MCB ngokususelwe kumkhawulo wamanje wesekethe emfushane futhi ungawaphazamisa ngokuphephile kanye nejika lohambo.Ama-RCBO ahlanganisa inhlanganisela ye-RCBO ne-MCB.Ungawakhetha ngokusekelwe kumjikelezo omfushane omkhulu wamanje nomthwalo, futhi angakhubaza ijika, aphazamise, futhi anikeze ukuvuza okukhulu kwamanje.

I-MCB inganikeza isivikelo kumasekhethi amafushane kanye ne-overcurrent, kuyilapho i-RCBO ingavikela kumaza okuvuza komhlaba, amasekhethi amafushane, nokudlulela ngokweqile.

I-RCBO ingcono njengoba ingavikela kumaza okuvuza komhlaba, amasekhethi amafushane, kanye ne-overcurrent, kuyilapho i-MCB ihlinzeka ngokuvikeleka kumasekhethi amafushane nokudlulela ngokweqile.Futhi, i-RCBO ingavikela ukushaqeka kukagesi namaphutha omhlaba, kodwa ama-MCB angeke avikele.

Ungayisebenzisa nini i-RCBO?

Ungasebenzisa i-RCBO ukuze uvikeleke ekushayweni kukagesi.Ikakhulukazi, ungayisebenzisa ukuze uphazamise amasokhethi amandla kanye ne-heater yamanzi, lapho ungathola khona amathuba okushaqeka kagesi.

Igama elithi RCBO limele iResidual Current Breaker enokuvikelwa Kwamanje.Ama-RCBO ahlanganisa ukuvikeleka emisinga yokuvuza komhlaba kanye nakuma-overcurrents (ukulayisha ngokweqile noma i-short-circuit).Umsebenzi wabo ungase uzwakale njengowe-RCD (Residual Current Device) ngokuya ngokuvikela okudlulele kanye nokuvikela isifunda esifushane, futhi lokho kuyiqiniso.Ngakho-ke yini umehluko phakathi kwe-RCD ne-RCBO?

I-RCBO yakhelwe ukuhlanganisa ukusebenza kwe-MCB ne-RCD ukuze kuqinisekiswe ukusebenza okuphephile kwamasekhethi kagesi.Ama-MCD asetshenziselwa ukuhlinzeka ngokuvikeleka kuma-over-currents futhi ama-RCD adalwa ukuthola ukuvuza komhlaba.Nakuba idivayisi ye-RCBO isetshenziselwa ukunikeza ukuvikeleka ekulayisheni ngokweqile, amasekhethi amafushane, namaza okuvuza komhlaba.

Inhloso yamadivayisi e-RCBO ukuhlinzeka ngokuvikelwa kumasekhethi kagesi ukuze kuqinisekiswe ukuthi isekethe kagesi isebenza ngokuphepha.Uma i-curse ingalingani, kuyindima ye-RCBO ukunqamula/ukuphula isekethe ukuze kuvinjwe umonakalo ongaba khona nobungozi kumjikelezo kagesi noma kumsebenzisi wokugcina.

Njengoba igama liphakamisa, ama-RCBO aklanyelwe ukuvikela ezinhlotsheni ezimbili zamaphutha.Amaphutha amabili avamile angenzeka phakathi kwemisinga kagesi ukuvuza komhlaba kanye ne-Over-Currents.

Ukuvuza komhlaba kwenzeka uma kuba nokuphuka ngephutha kwesekhethi okungadala izingozi ezifana nokushaqeka kukagesi.Ukuvuza komhlaba kuvame ukuvela ngenxa yokungafakwa kahle, izintambo ezingezinhle noma imisebenzi ye-DIY.

Kunezinhlobo ezimbili ezahlukene ze-over-current.Ifomu lokuqala liwukulayisha ngokweqile okwenzeka lapho kunezinhlelo zikagesi eziningi kakhulu kwisekethe eyodwa.Ukulayishwa ngokweqile kwesekhethi kagesi kukhulisa umthamo owelulekwayo futhi kungabangela ukulimala kwempahla kagesi namasistimu kagesi okungaholela ezingozini ezifana nokushaqeka kukagesi, umlilo, ngisho nokuqhuma.

Ifomu lesibili isifunda esifushane.Isekethe emfishane yenzeka lapho kunokuxhumana okungajwayelekile phakathi kokuxhumana okubili kwesekethe kagesi kuma-voltage ahlukene.Lokhu kungabangela umonakalo kumjikelezo kuhlanganise nokushisa ngokweqile noma umlilo ongase ube khona.Njengoba kushiwo ngaphambili, ama-RCD asetshenziselwa ukuvikela ekuvuzeni komhlaba futhi ama-MCB asetshenziselwa ukuvikela ngokumelene namanje.Nakuba ama-RCBO enzelwe ukuvikela kukho kokubili ukuvuza komhlaba nama-over-currents.

Ama-RCBO anezinzuzo eziningi ngokusebenzisa ama-RCD angawodwana kanye nama-MCB afaka lokhu okulandelayo:

1.RCBOs aklanywe njengedivayisi ethi "All in One".Idivayisi ihlinzeka ngokuvikeleka kwakho kokubili i-MCB ne-RCD okusho ukuthi asikho isidingo sokuzithenga ngokwehlukana.

2.Ama-RCBO ayakwazi ukubona amaphutha ngaphakathi kwesekhethi futhi akwazi ukuvimbela izingozi ezingaba khona zikagesi njengokushaqiswa kukagesi.

3.I-RCBO izophula ngokuzenzakalelayo isekethe kagesi lapho isekethe ingalingani ukuze kuncishiswe ukushaqeka kukagesi futhi kuvimbele ukulimala kwamayunithi amabhodi wabathengi.Ukwengeza, ama-RCBO azokhubaza isekethe eyodwa.

4.RCBOs inesikhathi esifushane sokufaka.Nokho, kuyalulekwa ukuthi osebenza ngogesi onesipiliyoni afake i-RCBO ukuze aqinisekise ukufakwa okushelelayo nokuphephile

5.Ama-RCBO asiza ukuhlolwa okuphephile nokugcinwa kwezinto zikagesi zisesimweni esihle

6.Idivayisi isetshenziselwa ukunciphisa ukukhubeka okungafuneki.

7.Ama-RCBO asetshenziselwa ukuthuthukisa ukuvikelwa kwedivayisi kagesi, umsebenzisi wokugcina, kanye nempahla yakhe.

I-RCBO yezigaba ezintathu iwuhlobo olukhethekile lwedivayisi yokuphepha esetshenziswa ezinhlelweni zikagesi zezigaba ezintathu, ezijwayelekile kuzilungiselelo zezohwebo nezimboni.Lawa madivayisi agcina izinzuzo zokuphepha ze-RCBO evamile, enikeza isivikelo ngokumelene nokushaqeka kukagesi ngenxa yokuvuza kwamanje kanye nezimo ezidlulele ezingaholela emlilweni kagesi.Ukwengeza, ama-RCBO ezigaba ezintathu aklanyelwe ukubhekana nobunzima bezinhlelo zamandla ezigaba ezintathu, okuwenza abaluleke kakhulu ekuvikeleni okokusebenza kanye nabasebenzi ezindaweni lapho kusetshenziswa khona lezo zinhlelo.
