UkuqondaAma-RCCB nama-MCBIzingxenye Ezibalulekile Zokuphepha Kukagesi
Ezweni lokufakwa kukagesi, ukuphepha kubaluleke kakhulu. Izingxenye ezimbili ezibalulekile ezidlala indima ebalulekile ekuqinisekiseni ukuphepha kukagesi yiziphuli zesekethe ezisele (ama-RCCB) kanye neziphuli zesekethe ezincane (ama-MCB). Lawa madivayisi amabili asebenza ngezinjongo ezahlukene kodwa avame ukusetshenziswa ndawonye ukuhlinzeka ngokuvikelwa okuphelele emaphutheni kagesi. Lesi sihloko sibheka ngokujulile imisebenzi, umehluko, kanye nokubaluleka kwama-RCCB nama-MCB ezinhlelweni zikagesi zanamuhla.
Kuyini i-RCCB?
I-RCCB, noma i-residual current current breaker, iyithuluzi lokuphepha elenzelwe ukuvimbela ukushaqeka kukagesi kanye nemililo kagesi ebangelwa amaphutha omhlaba. Isebenza ngokuqapha ibhalansi yamandla kagesi ageleza ngezintambo ezibukhoma nezingathathi hlangothi. Ngaphansi kwezimo ezijwayelekile, amandla kagesi kuzo zombili izintambo kufanele alingane. Kodwa-ke, uma kwenzeka iphutha, njengokuvuza okubangelwa ukwehluleka kokufakwa kwe-insulation noma othile othinta ucingo olubukhoma, i-RCCB ithola lokhu kungalingani. Uma ithola umehluko, ngokuvamile ophansi njengo-30 mA, iyakhubeka, inqamule amandla ngokushesha.
Ama-RCCB abalulekile ezindaweni lapho ingozi yokushaqeka kukagesi iphezulu khona, njengezindlu zangasese, amakhishi kanye nangaphandle. Ahlinzeka ngesendlalelo esibalulekile sokuvikela, ikakhulukazi emaqenjini asengozini njengezingane kanye nabantu asebekhulile.
Kuyini i-MCB?
Ngakolunye uhlangothi, ama-MCB (ama-miniature circuit breakers) aklanyelwe ukuvikela amasekethe ekugcwaleni ngokweqile kanye namasekethe amafushane. Ngokungafani nama-RCCB, agxile ekuvuzeni, ama-MCB aqapha ugesi ogeleza ngesekethe. Uma ugesi udlula umthamo olinganiselwe we-MCB ngenxa yokusetshenziswa ngokweqile (isibonelo, izinto eziningi zikagesi ezisetshenziswa ngesikhathi esisodwa) noma isekethe elifushane (iphutha elidala indlela yokumelana okuphansi), i-MCB izokhubeka futhi ivule isekethe.
Ama-MCB abalulekile ekuvimbeleni umonakalo ezintweni zikagesi kanye nezintambo, kanye nokunciphisa ingozi yomlilo kagesi ngenxa yokushisa ngokweqile. Avame ukusetshenziswa kuma-switchboard okuhlala kanye nawebhizinisi ukuqinisekisa ukuthi amasekethe asebenza ngaphakathi kwemingcele ephephile.
Umehluko omkhulu phakathi kwe-RCCB ne-MCB
Nakuba ama-RCCB nama-MCB womabili eyingxenye ebalulekile yokuphepha kukagesi, anemisebenzi ehlukene:
1. Umsebenzi: I-RCCB isetshenziselwa ukuvikela ephutheni lomhlaba kanye nokushaqeka kukagesi, kuyilapho i-MCB isetshenziselwa ukuvikela ekucindezelekeni ngokweqile kanye nokujikeleza okufushane.
2. Ukusebenza: Uhambo lwe-RCCB ngenxa yokungalingani kwamanje kanye nohambo lwe-MCB ngenxa yokudlula kwamandla kagesi.
3. Ukusetshenziswa: I-RCCB ivame ukusetshenziswa ezindaweni lapho ingozi yokushaqeka kukagesi iphezulu khona, kanti i-MCB isetshenziselwa ukuvikela amasekethe ekugcwaleni ngokweqile.
Ukubaluleka kokusebenzisa kokubili i-RCCB kanye ne-MCB
Ukuze kuvikelwe kahle kakhulu kagesi, kunconywa ukuthi i-RCCB kanye ne-MCB kuxhunywe ngokulandelana. Le nhlanganisela inikeza isivikelo esiphelele emaphutheni omhlaba kanye nokugcwala ngokweqile kwesekethe. Ekufakweni kukagesi okuvamile, i-MCB izovikela isekethe ekugcwaleni ngokweqile, kuyilapho i-RCCB izoqinisekisa ukuthi noma yikuphi ukuvuza kwamanje kuyatholakala futhi kusingathwa ngokushesha.
Ngamafuphi, ama-RCCB nama-MCB ayizingxenye ezibalulekile zezinhlelo zikagesi zanamuhla, futhi ngalinye lidlala indima ehlukile ekuvikeleni ezingozini zikagesi. Ukuqonda imisebenzi nomehluko wawo kubalulekile kunoma ngubani ohilelekile ekufakweni noma ekulungisweni kukagesi. Ngokusebenzisa womabili la madivayisi, abanikazi bezindlu namabhizinisi bangathuthukisa kakhulu ukuphepha kwabo kukagesi futhi bavikele impilo nempahla ezingozini zamaphutha kagesi.
