Ukuqonda Umehluko Phakathi Kwama-Circuit Breakers: i-RCCB, i-MCB kanye ne-RCBO

Yethula:

Ama-circuit breaker adlala indima ebalulekile ekuqinisekiseni ukuphepha kukagesi. Avimbela ukugcwala ngokweqile, ama-short circuit kanye namaphutha kagesi, avikela izimpilo kanye nemishini kagesi eyigugu. Kule bhulogi, sizobheka ngokujulile umhlaba wama-circuit breaker, sigxile kakhulu emehluko kanye nemisebenzi ye-RCCB, i-MCB kanye ne-RCBO.

1. Ulwazi oluyisisekelo ngama-circuit breaker:
Ngaphambi kokuba singene emininingwaneni, ake siqale siqonde ukuthi iyini i-circuit breaker. Empeleni, i-circuit breaker iyiswishi ezenzakalelayo esiza ukuvikela ama-circuit emonakalweni obangelwa ugesi omningi. Uma i-circuit igcwele ngokweqile noma ifushane, i-circuit breaker iphazamisa ukuhamba kukagesi, ivimbele izingozi ezingaba khona njengemililo kagesi.

2. I-Miniature circuit breaker (I-MCB):
Ama-MCB yiwona asetshenziswa kakhulu ezindaweni zokuhlala nezentengiselwano. Lawa madivayisi amancane kodwa aqinile aklanyelwe ukuvikela ugesi ongaphezu kwamandla okubangelwa ukugcwala ngokweqile noma ugesi omfushane. Ama-MCB atholakala ngezilinganiso zamanje ezahlukahlukene, okuvumela ukwenza ngokwezifiso ukuhlangabezana nezidingo zikagesi ezahlukene. Angasethwa kabusha ngesandla ngemva kokukhubeka, okuyinto elula ukusetshenziswa nsuku zonke.

3. I-Residual current breaker (I-RCCB):
Ama-RCCB, aziwa nangokuthi ama-Residual Current Devices (ama-RCD), ahlinzeka ngesendlalelo esengeziwe sokuphepha ngokuthola nokuvimbela imisinga yokuvuza komhlaba. Le misinga ivame ukwenzeka lapho umqhubi wesigaba esiphilayo ethinta ngengozi ingxenye eqhubayo yedivayisi kagesi, njengesivalo sensimbi. I-RCCB iqapha umusi ogeleza ngezintambo ezibukhoma nezingathathi hlangothi bese ikhubeka ngokushesha uma kutholwa ukungalingani. Lokhu kungalingani kungabangelwa ukuthintana komuntu nedivayisi enephutha, okunciphisa ingozi yokushaywa ugesi.

4. I-Residual current breaker (I-RCBO) ngokuvikelwa kokushisa ngokweqile:
I-RCBO ihlanganisa izici ze-MCB kanye ne-RCCB ukuze inikeze isivikelo esikabili ngokumelene nogesi odlulayo kanye nogesi osele. Lawa madivayisi ayisinqumo esiwusizo lapho kunesidingo sokuvikela isekethe ethile noma idivayisi ngayinye emaphutheni kagesi. I-RCBO ivame ukutholakala ezindaweni ezibucayi njengekhishi nezindlu zangasese lapho ukuxhumana namanzi kwandisa khona ingozi yezingozi zikagesi. Ngaphezu kwalokho, ama-RCBO avumela amasekethe ngamanye ukuthi ahlukaniswe ngesikhathi sokuxazulula izinkinga noma ukulungiswa ngenkathi kugcinwa konke ukufakwa kusebenza.

5. Umehluko omkhulu nezinzuzo:
a) I-MCB igxile ekuvimbeleni ukudlula kwamandla kagesi okubangelwa ukugcwala ngokweqile noma i-short circuit. Zilula ukuyisebenzisa, zingasethwa kabusha ngesandla, futhi zisetshenziswa kabanzi ngenxa yokungabizi kwazo nokutholakala kwazo.

b) I-RCCB inikeza isivikelo emifuleni yokuvuza komhlaba engase ibangelwe ukuthintana kwabantu nezinto zikagesi ezinephutha noma izintambo ezonakele. Lawa madivayisi andisa ukuphepha futhi avimbele izingozi zokushaqeka kukagesi.

c) I-RCBO inezinzuzo ze-MCB kanye ne-RCCB. Zihlinzeka ngokuvikelwa kwamanje okungaphezu kwamandla kagesi kanye nokusalayo futhi zilungele amasekethe abucayi noma izindawo ezidinga izinyathelo zokuphepha eziqinile.

6. Khetha i-circuit breaker efanele:
Ukukhetha i-circuit breaker efanele kuncike ezintweni ezahlukahlukene, njengomthwalo kagesi, ukuzwela kwe-circuit, kanye nezidingo ezithile zokuphepha. Njalo xhumana nochwepheshe kagesi noma unjiniyela kagesi ofanelekayo ongahlola izidingo zakho futhi ancome uhlobo lwe-circuit breaker olufanele kanye nesilinganiso sokufakwa kwakho.

Ngokufigqiwe:
Ukuqonda umehluko phakathi kwama-circuit breaker ahlukene njenge-RCCB, i-MCB kanye ne-RCBO kubalulekile ekugcineni ukuphepha kukagesi ezindaweni zokuhlala, zezentengiselwano kanye nezezimboni. I-MCB ivikela ekushiseni ngokweqile, i-RCCB ivikela ekuvuthweni komhlaba, kanti i-RCBO inikeza isivikelo esiphelele kuzo zombili lezi zici. Ngokukhetha i-circuit breaker efanele uhlelo lwakho lukagesi, ungavimbela izingozi ezingaba khona futhi uqinisekise ukuphepha kwabantu kanye nemishini.
