Umehluko kanye Nokusetshenziswa kwe-RCCB kanye ne-RCBO

UkuqondaI-RCCBfuthiI-RCBOIzingxenye Ezibalulekile Zokuphepha Kukagesi

Ukuphepha kubaluleke kakhulu ekufakweni kukagesi. Ama-Residual current breaker (ama-RCCB) nama-residual current circuit breaker ane-overcurrent protection (ama-RCBO) ngamadivayisi amabili abalulekile adlala indima ebalulekile ekuvikeleni abantu nempahla. Nakuba ukusetshenziswa kwawo kufana, ukuqonda umehluko kanye nokusetshenziswa kwama-RCCB nama-RCBO kubalulekile kunoma ubani osebenza endaweni kagesi noma ephephile.

Kuyini i-RCCB?

I-residual current breaker (RCCB) iyithuluzi lokuphepha elenzelwe ukuvimbela ukushaqeka kukagesi kanye nemililo kagesi ebangelwa amaphutha omhlaba. Isebenza ngokuqapha ibhalansi yamandla kagesi ageleza ngezintambo ezishisayo nezingathathi hlangothi. Uma ithola ukungalingani kwamandla kagesi, okungabonisa ukuvuza kwamandla kagesi (isibonelo, uma othile ethinta ngengozi intambo eshisayo), i-RCCB iyawa ngaphakathi kwama-millisecond bese inqamula isekethe. Lokhu kusabela okusheshayo kubalulekile ekuvimbeleni ukulimala okukhulu noma ukufa.

Ama-Residual current circuit breaker (ama-RCCB) avame ukukalwa ngama-milliamperes (mA) futhi atholakala ngamazinga ahlukahlukene okuzwela, njenge-30mA yokuzivikela komuntu siqu kanye ne-100mA noma i-300mA yokuvikela umlilo. Avame ukusetshenziswa ezinhlelweni zikagesi zokuhlala nezentengiselwano ukuthuthukisa ukuphepha, ikakhulukazi ezindaweni ezinamanzi, njengezindlu zangasese namakhishi.

Kuyini i-RCBO?

I-RCBO (i-Residual Current Circuit Breaker ene-Overcurrent Protection) ihlanganisa ukusebenza kwe-RCCB kanye ne-miniature circuit breaker (MCB). Lokhu kusho ukuthi i-RCBO ayivikeli nje kuphela emaphutheni omhlaba, kodwa futhi inikeza nokuvikelwa kwe-overcurrent ngokumelene nokulayisha ngokweqile kanye nama-short circuits.

Ukusebenza okubili kwe-RCBO kwenza kube ukukhetha okuguquguqukayo kokufakwa kukagesi kwesimanje. Ingasetshenziswa ukuvikela izifunda ngazinye, okuvumela ukulawula nokuphepha okunembe kakhudlwana. Isibonelo, uma ithuluzi elithile noma isifunda singasebenzi kahle, i-RCBO izokhubeka, ihlukanise iphutha ngaphandle kokuthinta lonke uhlelo lukagesi. Lesi sici siwusizo kakhulu ezindaweni zokuhlala ezinezifunda eziningi.

Umehluko omkhulu phakathi kwe-RCCB ne-RCBO

Nakuba ama-RCCB nama-RCBO womabili ebalulekile ekuphepheni kukagesi, asebenza ngezinjongo ezahlukene:

1. Ububanzi bokuvikelwa: I-RCCB inikeza ukuvikelwa kwamaphutha omhlaba kuphela, kanti i-RCBO inikeza ukuvikelwa kwamaphutha omhlaba kanye nokweqisa komoya (ukulayisha ngokweqile kanye nokujikeleza okufushane).

2.Isicelo: I-RCCB ivame ukusetshenziswa kanye ne-MCB ukuhlinzeka ngokuvikelwa okuphelele, kuyilapho i-RCBO ingasetshenziswa ngokuzimela ukuvikela isekethe eyodwa.

3. Ukufakwa: Ukufakwa kwe-RCCB kanye ne-MCB kuthatha isikhala esiningi ebhodini lokusabalalisa, kuyilapho i-RCBO ingahlanganisa imisebenzi emibili ibe yidivayisi eyodwa, ngaleyo ndlela isindise isikhala.

Ukukhetha phakathi kwe-RCCB ne-RCBO

Uma ukhetha phakathi kwe-RCCB ne-RCBO, cabangela izidingo ezithile zesistimu yakho kagesi. Uma udinga ukuvikelwa kwephutha lomhlabathi futhi usuvele ufake i-MCB, i-RCCB inganele. Kodwa-ke, ekufakweni okusha noma ekuthuthukiseni izinhlelo ezikhona, ama-RCBO ngokuvamile anconywa ngenxa yezici zawo zokuvikela eziphelele kanye nomklamo wokonga isikhala.

Kafushane

Ngamafuphi, ama-RCCB nama-RCBO ayizingxenye ezibalulekile zokuphepha kukagesi. Ukuqonda imisebenzi yawo, umehluko, kanye nezinhlelo zokusebenza kungakusiza ukuthi wenze izinqumo ezinolwazi lapho uklama noma uthuthukisa uhlelo lwakho lukagesi. Kungakhathaliseki ukuthi ungumnikazi wendlu, uchwepheshe kagesi, noma uchwepheshe wezokuphepha, ukubeka phambili ukusetshenziswa kwala madivayisi kunganciphisa kakhulu ingozi yezingozi zikagesi, kuqinisekiswe indawo ephephile kuwo wonke umuntu.
