Ukuqonda ama-RCCB kagesi: Umhlahlandlela Ophelele
Ezweni lokuphepha kukagesi, ama-residual current circuit breakers (ama-RCCB) adlala indima ebalulekile ekuvikeleni abantu nempahla ezingozini zikagesi. Lesi sihloko sizogxila encazelweni, emsebenzini, kanye nokusetshenziswa kwama-RCCB kagesi, sinikeze ukuqonda okuphelele kwale divayisi ebalulekile.
Kuyini i-RCCB?
I-RCCB, eyaziwa nangokuthi idivayisi yamanje eseleyo (i-RCD), iyithuluzi lokuphepha elisetshenziselwa ukuvimbela ukushaqeka kukagesi kanye nemililo kagesi ebangelwa amaphutha omhlaba. Isebenza ngokuqapha ibhalansi yamandla kagesi egeleza ngezintambo ezishisayo nezingathathi hlangothi zesekethe. Uma kutholwa ukungalingani kwamandla kagesi (okungenzeka lapho ukuvuza kwamandla kagesi kuya phansi), i-RCCB iyayinqamula ngokushesha isekethe, inciphise ingozi yokushaqeka kukagesi kanye nomlilo.
Isebenza kanjani i-RCCB?
Ama-RCCB asebenza ngokusekelwe ku-differential current. Ngokuvamile, ugesi ogeleza ku-live conductor kufanele ulingane nogesi ogeleza ku-neutral conductor. Kodwa-ke, uma kwenzeka iphutha, njengomuntu othinta i-live conductor noma i-appliance ephukayo, omunye ugesi ungageleza uye phansi. I-RCCB ingawubona lo mehluko (ngokuvamile uphansi njenge-30 milliamperes (mA)) bese ikhubeka ngaphakathi kwama-millisecond.
Le mpendulo esheshayo ibalulekile ekuvimbeleni ukulimala okukhulu noma ukufa ngenxa yokushaqeka kukagesi. Ama-RCCB atholakala ngezilinganiso ezahlukahlukene zamanje, kufaka phakathi i-30mA yokuzivikela komuntu siqu kanye ne-100mA noma i-300mA yokuvikela umlilo, okuvumela abasebenzisi ukuthi bakhethe idivayisi efanele izidingo zabo.
Izinhlobo zama-RCCB
Kunezinhlobo eziningana zama-RCCB kagesi, ngalinye linenhloso ehlukile:
1. I-RCCB enama-pole amabili: Isetshenziselwa amasekethe esigaba esisodwa, inama-terminal amabili okuxhumana okubukhoma nokungakhethi.
2. I-RCCB enama-pole amane: Yakhelwe amasekethe anezigaba ezintathu, ineziphetho ezine ukuze ikwazi ukwamukela izigaba ezintathu kanye nomqhubi ongathathi hlangothi.
3. Uhlobo lwe-AC RCCB: Ithola ugesi osele oshintshashintshayo (AC).
4. Uhlobo A RCCB: Iyakwazi ukubona i-AC kanye nokushaya amaza asele e-DC, afanelekela amasekethe anemishini kagesi.
Ukusetshenziswa kwe-RCCB
Ama-RCCB asetshenziswa kabanzi ezindaweni zokuhlala, zezentengiselwano, kanye nezezimboni. Emakhaya, avame ukufakwa kuphaneli yokusabalalisa eyinhloko ukuvikela amasekethe anika amandla izinto zikagesi, izibani, kanye nezindawo zokuphuma. Ezakhiweni zezentengiselwano, ama-RCCB avikela imishini futhi agcina abasebenzi namakhasimende bephephile. Ezindaweni zezimboni, abalulekile ekuvikeleni imishini nasekuvimbeleni isikhathi esibizayo sokungasebenzi ngenxa yamaphutha kagesi.
Izinzuzo zokusebenzisa i-RCCB
Kunezinzuzo eziningi zokufaka i-RCCB kagesi:
- Ukuphepha Okuthuthukisiwe: Ama-RCCB anciphisa kakhulu ingozi yokushaqeka kukagesi kanye nomlilo, okunikeza abasebenzisi ukuthula kwengqondo.
- Ukuthobela Imithetho: Izindinganiso eziningi zokuphepha kagesi kanye namakhodi okwakha zidinga ukufakwa kwe-RCCB ezicelweni ezithile ukuqinisekisa ukuthobela imithetho kanye nokuphepha.
- Ukuvikelwa Okungabizi: Nakuba kudingeka ukutshalwa kwezimali kokuqala ukuze kuthengwe futhi kufakwe i-RCCB, ukonga kwesikhathi eside ekuvimbeleni izingozi kanye nomonakalo wempahla kukhulu kakhulu.
Ngokufigqiwe
Kalula nje, ama-RCCB ayizingxenye ezibalulekile ezinhlelweni zikagesi zanamuhla, ahlinzeka ngokuvikelwa okubalulekile ezingozini zikagesi. Ukuqonda imisebenzi yawo, izinhlobo, kanye nezinhlelo zokusebenza kungasiza abantu ngabanye kanye namabhizinisi ukuthi benze izinqumo zokuphepha kukagesi ezinolwazi. Ngokufaka ama-RCCB ekufakweni kukagesi, abasebenzisi bangathuthukisa ukuphepha, balandele imithetho, futhi ekugcineni bavikele impilo kanye nempahla ezingozini zamaphutha kagesi. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukubaluleka kwama-RCCB ekuqinisekiseni ukuphepha kukagesi kuzokhula kuphela, kubenze babe yingxenye ebalulekile yanoma yiluphi uhlelo lukagesi.
