Ukugcina Amasekethe Asekhaya Ephephile: Ukuqonda Ukubaluleka Kwama-Earth Residual Circuit Breakers

Ukubaluleka kwama-residual current breakers ezinhlelweni zikagesi

Ezweni lanamuhla elithuthukile nelesimanje, ukuphepha kukagesi kufanele kube yinto eza kuqala ezakhiweni zokuhlala nezebhizinisi. Njengoba izinto zikagesi nezinhlelo zisetshenziswa kakhulu, ingozi yezingozi zikagesi kanye nemililo iyanda. Yilapho ama-Residual Current Circuit Breakers (RCCB) edlala khona indima ebalulekile ekuhlinzekeni ngokuvikelwa nokuqinisekisa ukuphepha kokufakwa kukagesi.

I-RCCB, eyaziwa nangokuthiidivayisi yamanje esele (i-RCD), iyithuluzi lokuphepha likagesi elenzelwe ukunqamula ngokushesha ugesi lapho kutholwa ukungalingani kokugeleza kwamandla kagesi. Lokhu kungalingani kungabangelwa izintambo ezinephutha noma ukuvuza okuvela ekuthinteni kwabantu izintambo eziphilayo noma izinto zikagesi ezinephutha. Ngokuthola nokunqamula ugesi ngesikhashana nje, ama-RCCB asiza ekuvimbeleni ukunqamula ugesi, ukunqamula ugesi kanye nemililo kagesi.

Enye yezinzuzo eziyinhloko zokufakaAma-RCCBEzinhlelweni zikagesi kukhona ikhono lokuvikela ekuthintaneni okuqondile nokungaqondile nezingxenye eziphilayo. Lokhu kusho ukuthi noma ngabe umuntu uthintana ngengozi nentambo ephilayo, i-RCCB izophazamisa ngokushesha ukuhamba kukagesi, ivimbele noma yikuphi ukulimala noma ukufa okukhulu. Ngaphezu kwalokho, ama-RCCB angathola futhi avimbele amaphutha okushisa, aqinisekise ukuthi ukufakwa kukagesi kuphephile futhi kuhambisana nemithetho edingekayo.

Esinye isici esibalulekile sama-RCCB yikhono lawo lokuvikela kuma-residual currents angavela ngenxa yokwehluleka kwemishini, ukukhubazeka kwezintambo noma izici zemvelo ezifana nomswakama. La ma-residual currents angaba yingozi enkulu, ikakhulukazi ezindaweni ezimanzi noma zangaphandle, futhi i-RCCB yenzelwe ukuthola nokunqamula ugesi ezimweni ezinjalo, ngaleyo ndlela kuncishiswe ingozi yokushaqeka kukagesi nomlilo.

Ngaphezu kokuthuthukisa ukuphepha kukagesi, ama-RCCB nawo adlala indima ebalulekile ekunciphiseni ingozi yomlilo ezakhiweni. Imililo kagesi ingabangelwa yizinto ezahlukahlukene, okuhlanganisa ama-short circuits, ukulayisha ngokweqile, kanye namaphutha omhlaba. Ngokuhlukanisa ngokushesha ama-circuits noma imishini enephutha, ama-RCCB anganciphisa amathuba omlilo, ngaleyo ndlela avikele impilo kanye nempahla.

Kuyafaneleka ukuqaphela ukuthi emazweni amaningi nasezifundeni, ukufakwa kwama-RCCB ezinhlelweni zikagesi kuyimfuneko esemthethweni. Ngokulandela le mithethonqubo nezindinganiso, abanikazi bezakhiwo kanye nabakhi bezokwakha kagesi bangaqinisekisa ukuphepha nokuvikelwa kwabantu abasebenzisa ukufakwa kukagesi.

Ngamafuphi, ama-earth leakage circuit breakers ayingxenye ebalulekile yezinhlelo zikagesi zanamuhla. Ngokuqapha njalo ugesi wamanje kanye nokukhipha amandla ngokushesha lapho kwenzeka ukungalingani noma iphutha, ama-RCCB ahlinzeka ngesendlalelo esibalulekile sokuvikela ekushayweni ugesi, ukushayiswa ugesi, kanye nemililo kagesi. Ngakho-ke, abanikazi, osonkontileka bakagesi kanye nabantu ngabanye kumele baqaphele ukubaluleka kwe-RCCB futhi baqinisekise ukuthi ikhona kuzo zonke izikhungo zikagesi. Phela, uma kukhulunywa ngokuphepha kukagesi, ukuvimbela kungcono njalo kunokubhekana nemiphumela yengozi noma umlilo.
