I-RCD ye-Circuit Breaker: Isixazululo Sokuvikela Okubili

UkuqondaAma-Circuit Breaker nama-RCDIzingxenye Ezibalulekile Zokuphepha Kukagesi

Emkhakheni wokuphepha kukagesi, izingxenye ezimbili ezibalulekile zemishini ziyagqama: ama-circuit breaker kanye namadivayisi asele asebenza njengamanje (ama-RCD). Zombili zidlala indima ebalulekile ekuvikeleni uhlelo lwamandla, futhi okubaluleke kakhulu, impilo yabantu. Le bhulogi igxila emisebenzini, umehluko, kanye nokubaluleka kwala madivayisi ukuze kunikezwe abanikazi bezindlu, ochwepheshe bakagesi, nanoma ubani onesifiso sokuphepha kukagesi ukuqonda okuphelele.

Kuyini i-circuit breaker?

I-circuit breaker iyiswishi kagesi ezenzakalelayo eyenzelwe ukuvikela i-electronic circuit emonakalweni obangelwa ukugcwala ngokweqile noma i-short circuit. Umsebenzi wayo oyinhloko ukuphazamisa ukugeleza kwamanje ngemva kokuthola iphutha. Ngokungafani nama-fuse, asebenza kanye futhi okumele ashintshwe, ama-circuit breaker angasethwa kabusha (ngesandla noma ngokuzenzakalelayo) ukuze aqale kabusha ukusebenza okuvamile.

Uhlobo lwe-circuit breaker

1. I-Miniature Circuit Breaker (MCB): I-MCB isetshenziswa kumasekethe aphansi kagesi ukuvikela ekugcwaleni ngokweqile kanye namasekethe amafushane. Avame ukutholakala ezakhiweni zokuhlala nezebhizinisi.
2. I-Molded Case Circuit Breaker (MCCB): I-MCCB ifaneleka ezinhlelweni zokusebenza ezinamandla aphezulu, inikeza izilungiselelo zokuhamba ezilungisekayo, futhi isetshenziswa ezindaweni zezimboni.
3. Isivimbeli Sokujikeleza Kwesiphazamiso Sesiyingi Sesiyingi Somhlabathi (i-GFCI): Ama-GFCI aklanyelwe ukuvikela amaphutha omhlaba futhi abalulekile ezindaweni ezinomswakama ophezulu njengezindlu zangasese namakhishi.

Kuyini i-RCD?

Idivayisi Yamanje Esele (i-RCD), eyaziwa nangokuthi i-Ground Fault Circuit Interrupter (GFCI) kwezinye izindawo, iyidivayisi evula ngokushesha isekethe kagesi ukuvimbela ukulimala okukhulu okuvela ekushaqekeni kukagesi okuqhubekayo. Isebenza ngokuthola ukungalingani phakathi kwezintambo ezibukhoma nezingathathi hlangothi. Uma ugesi ogeleza ngentambo ebukhoma uhlukile kunogesi ogeleza ngentambo engathathi hlangothi, i-RCD izokhubeka, inqume ugesi.

Uhlobo lwe-RCD

1. I-RCD Elungisiwe: Ifakwe kuyunithi yabathengi (ibhokisi le-fuse) futhi ivikela amasekethe amaningi.
2. I-Socket RCD: Yakhelwe ezisekelweni ezijwayelekile ukuze ihlinzeke ngokuvikelwa kwamadivayisi axhunyiwe.
3. I-RCD Ephathekayo: Ixhuma kunoma iyiphi indawo yokukhipha ejwayelekile, ihlinzeka ngesivikelo kunoma iyiphi idivayisi exhunywe kuyo.

Umehluko Phakathi kwe-Circuit Breaker ne-RCD

Nakuba womabili amadivayisi ebalulekile ekuphepheni kukagesi, afeza izinjongo ezahlukene:

- Umsebenzi: I-circuit breaker ivikela kuma-overcurrent kanye nama-short circuits, kuyilapho i-RCD ivikela kumaphutha omhlaba kanye nokushaqeka kukagesi.
- UKUSEBENZA: I-circuit breaker iyahamba lapho ugesi udlula izinga elibekiwe kusengaphambili kanye ne-RCD iyahamba lapho kutholwa ukungalingani phakathi kogesi ophilayo nowe-neutral.
- Setha kabusha: Womabili amadivayisi angasethwa kabusha ngemva kokukhubeka, kodwa imbangela yohambo kumele ikhonjwe futhi ilungiswe ngaphambi kokusetha kabusha.

Ukubaluleka Kwama-Circuit Breakers nama-RCD

1. Ukuvimbela Imililo Kagesi: Ama-circuit breaker avimbela ukushisa ngokweqile kanye nemililo engaba khona ngokunqamula ugesi oweqile.
2. Vikela Izinto Zikagesi: Lawa madivayisi avikela izinto zikagesi ekulimaleni ngokuphazamisa isekethe ngesikhathi sephutha.
3. KUSINDISA UKUPHILA: Ama-RCD abaluleke kakhulu ekuvimbeleni ukushaqeka kukagesi okubulalayo. Abaluleke kakhulu ezindaweni ezinamanzi, okungandisa ingozi yokushaqeka kukagesi.

Ngokufigqiwe

Ukuqonda indima kanye nomehluko phakathi kwama-circuit breaker nama-RCD kubalulekile ekugcineni ukuphepha kukagesi kunoma iyiphi indawo. Ama-circuit breaker avikela kuma-overcurrent kanye nama-short circuits, kuyilapho ama-RCD ehlinzeka ngokuvikelwa okubalulekile ekushayweni kukagesi. Ndawonye, ​​lawa madivayisi akha inethi yokuphepha ephelele eqinisekisa ukuthi izinhlelo zikagesi zisebenza ngokuphepha nangokusebenza kahle. Kungakhathaliseki ukuthi ungumnikazi wendlu, uchwepheshe kagesi, noma umuntu othanda ukuphepha kukagesi, ukuqonda ukuthi la madivayisi asebenza kanjani nokuthi kungani ebalulekile kungakusiza ukuthi wenze izinqumo ezinolwazi futhi ugcine indawo yokuhlala noma yokusebenza ephephile.
