Umehluko kanye Nokusetshenziswa kwe-RCCB kanye ne-RCBO

UkuqondaAma-RCCBfuthiAma-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 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 kutholwa ukungalingani kwamandla kagesi (isibonelo, uma othile ethinta intambo eshisayo, okungase kubonise ukuvuza kwamandla kagesi), i-RCCB iyawa ngaphakathi kwama-millisecond bese inqamula isekethe. Le mpendulo esheshayo ibalulekile 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 kwenzeka iphutha kusifunda, i-RCBO izokhubeka, ihlukanise leso sifunda ngaphandle kokuthinta ezinye izifunda. Lesi sici siwusizo kakhulu ezindaweni zokuhlala ezinezifunda eziningi.

Umehluko omkhulu phakathi kwe-RCCB ne-RCBO

Nakuba ama-RCCB nama-RCBO womabili ebalulekile ekuphepheni kukagesi, ukusetshenziswa kwawo kuhlukile kakhulu:

1. Umsebenzi: I-RCCB inikeza ukuvikelwa kwephutha lomhlabathi kuphela, kuyilapho i-RCBO inikeza kokubili ukuvikelwa kwephutha lomhlabathi kanye nokuvikelwa kokushisa okuphezulu.

2.Ukusebenza: Ama-RCCB avame ukusetshenziswa kanye nama-MCB, kuyilapho ama-RCBO engathatha indawo yamadivayisi womabili, ngaleyo ndlela enze uhlelo lokuvikela isekethe lube lula.

3. Izindleko Nesikhala: Njengoba ama-RCBO enemisebenzi emibili, angase abize kakhulu kune-RCCB. Kodwa-ke, njengoba ama-RCBO ehlanganisa amadivayisi amabili abe yinye, angonga isikhala ekhabhinethini lokusabalalisa.

4. Indlela Yokuhamba: I-RCCB iyahamba lapho kutholwa ukungalingani kwamanje, kanti i-RCBO iyahamba lapho kwenzeka iphutha lomhlabathi kanye nomsinga ongaphezulu.

Kafushane

Ngamafuphi, ama-RCCB nama-RCBO ayizingxenye ezibalulekile zokuqinisekisa ukuphepha kukagesi. Ama-RCCB avikela kakhulu emaphutheni omhlaba, okwenza abe yimishini ebalulekile ezindaweni ezinobungozi obukhulu. Ngakolunye uhlangothi, ama-RCBO ahlanganisa ukuvikelwa kwamaphutha omhlaba nokuvikelwa kokushisa ngokweqile, okuhlinzeka ngesisombululo esiphelele sezinhlelo zikagesi zesimanje.

Lapho uklama noma uthuthukisa imishini kagesi, kubalulekile ukucabangela izidingo ezithile zemvelo kanye nezinga lokuvikelwa elidingekayo. Ukuqonda umehluko kanye nokusetshenziswa kwama-RCCB nama-RCBO kungasiza ochwepheshe bezogesi kanye nabaninikhaya ukuba benze izinqumo ezinolwazi ezithuthukisa ukuphepha nokuthembeka kwezinhlelo zabo zikagesi. Kungakhathaliseki ukuthi ukhetha i-RCCB noma i-RCBO, ukubeka phambili ukuphepha kukagesi kuhlale kuyisinqumo esifanele.
