I-RCD/RCCB/RCBO: Ukuvikelwa Okuphelele Kukagesi

UkuqondaI-RCD, I-RCBOfuthiI-RCCB: Amadivayisi Okuphepha Kagesi Ayisisekelo

Ezweni lokuphepha kukagesi, uzovame ukuhlangana namagama anjenge-RCD, i-RCBO kanye ne-RCCB. Lawa madivayisi adlala indima ebalulekile ekuvikeleni abantu kanye nempahla emaphutheni kagesi. Ukuqonda imisebenzi yawo, umehluko kanye nokusetshenziswa kwawo kubalulekile kunoma ubani ohilelekile ekufakweni noma ekulungisweni kukagesi.

Kuyini i-RCD?

I-RCD, noma idivayisi yamanje eseleyo, iyidivayisi yokuphepha eyenzelwe ukuvimbela ukushaqeka kukagesi kanye nemililo kagesi ebangelwa amaphutha omhlaba. Isebenza ngokuqapha njalo ugesi ogeleza ngesekethe. Uma ithola ukungalingani phakathi kwezintambo ezishisayo nezingathathi hlangothi (okubonisa ukuthi ugesi uyavuza emhlabathini), ivula isekethe ngaphakathi kwama-millisecond. Lokhu kusabela okusheshayo kungasindisa izimpilo, okwenza ama-RCD abe yingxenye ebalulekile yezinhlelo zikagesi zokuhlala nezebhizinisi.

Ama-RCD avame ukusetshenziswa kumasekethe ahlinzeka ngemishini yangaphandle, izindlu zangasese kanye namakhishi lapho ingozi yokushaqeka kukagesi iphezulu khona. Afika ngezindlela ezahlukene, kufaka phakathi ama-RCD aphathekayo okufakwa kwesikhashana kanye nama-RCD aqinile afakwe kumayunithi abathengi.

Kuyini i-RCCB?

I-RCCB, noma i-residual current circuit breaker, uhlobo olukhethekile lwe-RCD. Umsebenzi oyinhloko we-RCCB ukuthola amaphutha omhlaba nokuvula i-circuit ukuvimbela ukushaqeka kukagesi. Ngokungafani nama-circuit breaker ajwayelekile avikela ekugcwaleni ngokweqile kanye nama-short circuit, ama-RCCB agxila kuphela ekuvikeleni ukuvuza komhlaba.

Ama-RCCB avame ukusetshenziswa ezinhlelweni zikagesi zasemakhaya nezentengiselwano ukuthuthukisa ukuphepha. Atholakala ngezilinganiso ezahlukene, okuvumela abasebenzisi ukuthi bakhethe idivayisi efanele izidingo ezithile zokufakwa kwabo kukagesi. Nakuba ama-RCCB enikeza isivikelo esihle kakhulu ekushayweni ugesi, awahlinzeki ngesivikelo ekucindezelweni ngokweqile noma kuma-short circuits, okuyilapho amanye amadivayisi eqala khona ukusebenza.

Kuyini i-RCBO?

I-RCBO, noma i-residual current breaker enokuvikelwa kwe-overcurrent, ihlanganisa imisebenzi ye-RCD kanye ne-circuit breaker. Lokhu kusho ukuthi i-RCBO ayivikeli nje kuphela emaphutheni omhlaba, kodwa futhi nasekucindezelweni ngokweqile kanye nama-short circuit. Lokhu kusebenza okubili kwenza i-RCBO ibe ukukhetha okuguquguqukayo kokufakwa kukagesi kwesimanje.

Ama-RCBO awusizo kakhulu lapho isikhala silinganiselwe, njengoba engathatha indawo ye-RCD kanye ne-circuit breaker ngesikhathi esisodwa. Lokhu akugcini nje ngokwenza kube lula i-switchboard, kodwa futhi kuthuthukisa ukuphepha ngokuhlinzeka ngokuvikelwa okuphelele kudivayisi eyodwa. Alungele izindawo zokuhlala, izakhiwo zebhizinisi kanye nezicelo zezimboni.

Umehluko Omkhulu

Nakuba ama-RCD, ama-RCCB nama-RCBO enezinhloso ezifanayo ekuphepheni kukagesi, imisebenzi yawo ihluke kakhulu:

- I-RCD: Isetshenziswa kakhulu ukuthola amaphutha omhlaba kanye nokunqamula isekethe ukuvimbela ukushaqeka kukagesi. Ayinikezi ukuvikelwa kokudlula ngokweqile noma kwesekethe emfushane.

- I-RCCB: I-RCD eyenzelwe ngqo ukuthola amaphutha omhlaba. Njenge-RCD, ayivikeli ekucindezelweni ngokweqile noma kuma-short circuits.

- I-RCBO: Ihlanganisa ukusebenza kwe-RCD kanye ne-circuit breaker ukuvikela amaphutha omhlaba kanye nokugcwala ngokweqile/ama-short circuits.

Kafushane

Ngamafuphi, ama-RCD, ama-RCCB, nama-RCBO ngamadivayisi abalulekile okuphepha kukagesi. Ukuqonda imisebenzi yawo kanye nomehluko kubalulekile ekukhetheni isivikelo esifanele sohlelo lwakho lukagesi. Kungakhathaliseki ukuthi ungumnikazi wendlu, usogesi, noma umphathi wesikhungo, ukuqonda la madivayisi kungakusiza wenze izinqumo eziphephile futhi uvimbele izingozi zikagesi. Uma ucabanga ukufaka la madivayisi, hlala uthintana nosogesi ofanelekayo ukuqinisekisa ukuthi uyahambisana namakhodi nezindinganiso zendawo.
