I-Circuit Breaker kanye ne-RCD: Isiqinisekiso Samandla Aphephile

Ama-Circuit Breaker nama-RCDUkuqonda Indima Yabo Ekuphepheni Kukagesi

Ezweni lokuphepha kukagesi, izingxenye ezimbili ezibalulekile zivame ukusebenza: ama-circuit breaker kanye namadivayisi amanje asele (ama-RCD). Nakuba zombili zenzelwe ukuvikela ama-circuit nokuvimbela izingozi, zisebenza ngendlela ehlukile futhi zenzelwe imisebenzi ethile. Ukuqonda indima yama-circuit breaker kanye nama-RCD kubalulekile kunoma ubani ohilelekile ekufakweni kukagesi, ekugcinweni noma ekuphepheni.

Kuyini i-circuit breaker?

I-circuit breaker iyiswishi kagesi ezenzakalelayo eyenzelwe ukuvikela isekethe kagesi emonakalweni obangelwa ukugcwala ngokweqile noma isekethe esifushane. Lapho ugesi ogeleza ngesekethe udlula izinga elinqunyiwe, i-circuit breaker iphazamisa ukuhamba kukagesi, "ivula" isekethe ngempumelelo. Lesi senzo sivikela uhlelo lukagesi kanye nemishini exhunyiwe ngokuvimbela ukushisa ngokweqile kanye nomlilo ongaba khona.

Kunezinhlobo eziningi zama-circuit breaker, okuhlanganisa:

1. I-Miniature Circuit Breaker (MCB): Isetshenziswa ezisetshenziswayo ze-voltage ephansi ukuvikela ekugcwaleni ngokweqile kanye nama-short circuits.
2. I-Residual Current Circuit Breaker (RCCB): Lawa madivayisi athola ukungalingani kwamanje futhi aphule isekethe ukuze avimbele ukushaqeka kukagesi.
3. I-Eleakage Circuit Breaker (ELCB): Njenge-RCCB, i-ELCB ivikela emaphutheni omhlaba kanye nemisinga yokuvuza.

Kuyini i-RCD?

Idivayisi Yamanje Esele (RCD), eyaziwa nangokuthi i-Residual Current Circuit Breaker (RCCB), iyidivayisi yokuphepha evula isekethe noma nini lapho ithola ukungalingani kwamandla kagesi phakathi kwama-conductor aphilayo nalawo angathathi hlangothi. Lokhu kungalingani kwenzeka lapho kwenzeka ukungasebenzi kahle, njengalapho umuntu ethinta ucingo oluphilayo ngengozi, okubangela ukushaywa ugesi noma ukushaywa ugesi.

Ama-RCD aklanyelwe ukusabela ngokushesha (ngokuvamile ngaphakathi kwama-millisecond angu-30) ukuvimbela ukulimala okukhulu noma ukufa. Abaluleke kakhulu ezindaweni ezimanzi njengezindlu zangasese namakhishi, lapho ingozi yokushaqeka kukagesi iphezulu khona. Ama-RCD angafakwa njengamadivayisi azimele noma ahlanganiswe kuma-circuit breaker ukuze ahlinzeke ngokuvikelwa okubili.

Ukubaluleka kwama-circuit breakers nama-RCD

Ama-circuit breaker nama-RCD adlala indima ebalulekile ekuqinisekiseni ukuphepha kukagesi. Ama-circuit breaker avikela ekugcwaleni ngokweqile kanye nama-short circuits, kuyilapho ama-RCD egxile ekuvimbeleni ukushaqeka kukagesi ngokuthola ukuvuza kwamanje. Ndawonye akha uhlelo oluphelele lokuphepha olunciphisa ingozi yezingozi zikagesi.

1. Ukuvikelwa Komlilo: Ama-circuit breaker avikela ekushiseni ngokweqile kanye nemililo engaba khona ebangelwa ukugcwala ngokweqile kwe-circuit. Angakhubeka uma kudingeka, avikele izintambo zikagesi kanye nezinto zikagesi ekulimaleni.

2. Ukuvikelwa Kokushaqeka: Ama-RCD abalulekile ekuvikeleni abantu ekushaqekeni kukagesi. Ngokunqamula isekethe ngokushesha lapho kutholakala iphutha, anganciphisa kakhulu ingozi yokulimala noma ukufa okukhulu.

3. UKUHAMBISANA NEKHODI: Amakhodi amaningi okuphepha kagesi adinga ukufakwa kwama-circuit breaker nama-RCD ezindaweni zokuhlala nezentengiselwano. Ukuthobela imithetho akugcini nje ngokuqinisekisa ukuphepha kodwa futhi kuvikela abanikazi bezindawo ekubeni nesibopho esisemthethweni.

Ngokufigqiwe

Ngamafuphi, ama-circuit breaker kanye nezivikelo zokuvuza komhlaba ziyizingxenye ezibalulekile zezinhlelo zokuphepha zikagesi. Ama-circuit breaker avikela ekugcwaleni ngokweqile kanye nama-short circuits, kuyilapho ama-RCD ehlinzeka ngokuvikelwa okubalulekile ekushaqekeni kukagesi. Ukuqonda umsebenzi nokubaluleka kwala madivayisi kubalulekile kunoma ubani osebenza ngamandla kagesi. Ngokuqinisekisa ukuthi ama-circuit breaker kanye nama-RCD afakwe futhi anakekelwa kahle, singakha indawo ephephile kithi nakwabanye futhi sinciphise ingozi yezingozi zikagesi emakhaya ethu nasezindaweni zokusebenza.
