Ukuqonda ukubaluleka kwabaphuke ama-miniature circuit breakers (MCBS) ekuphepheni kukagesi

Emkhakheni wezokuphepha kagesi, abaphukileyo bezesekeli abancane (IMCBS) Dlala indima ebalulekile ekuvikeleni amasekethe ekugcwalisekeni ngokweqile kanye nemibuthano emifushane. Lawa madivaysi enzelwe ukuphazamisa ngokuzenzakalelayo ukugeleza kukagesi lapho kutholwa iphutha, kuvinjelwa izingozi ezingaba khona njengomlilo noma ukushaqeka kukagesi. Ngezinketho eziningi ezitholakalayo kufaka phakathi i-AC DC Residial yamanje ye-1P 2p 3p 4p, i-Resiual Cratiop Prealit Crealer, i-RCCB, i-RCBO ne-ELCB, kubalulekile ukuqonda ukubaluleka kwe-MCB ekuqinisekiseni ukuphepha kwezinhlelo zikagesi.

I-MCBS yakhelwe ukuhlinzeka ngokuvikelwa okuthembekile ezinhlelweni ezahlukahlukene zikagesi, ezivela ezindaweni zokuhlala nezindawo zezimboni. Zitholakala ekucushweni okuhlukahlukene kwezine, kufaka phakathi i-1P, 2P, 3P ne-4P, ukufeza izidingo ezithile zokufakwa kukagesi okuhlukile. Noma ngabe kuvikela amaseliphu esigameko esisodwa noma ama-3 wesigaba ezintathu, i-MCB inikela ngezixazululo eziguquguqukayo ukuvikela amasistimu kagesi emaphutheni.

Enye yezinto ezibalulekile ze-MCBS yikhono labo lokuthola ngokushesha futhi baphendule ekuvumeni okuphezulu kanye nemibuthano emifushane. Lokhu kuphendula okusheshayo kusiza ukunciphisa ubungozi bomonakalo emishini kagesi kanye ne-wiring futhi kunciphise amandla emithelo kagesi. Ngokwengeziwe, i-MCB inomklamo oyi-compact futhi osindisa isikhala, okwenza ilungele ukufakwa ngesikhala esilinganiselwe.

Ngaphezu kokuvikelwa ngokweqile, abaphukileyo bemisilinga abancane futhi bahlinzeka ngokuvikelwa ukuvuza futhi bavame ukubizwa ngokuthi ama-residial breaker akhona (i-RCCB) noma amadivaysi avuzayo okuvikela amanje (RCD). Lawa madivaysi abucayi ngokuthola futhi aphule umjikelezo lapho kuvuza khona lapho kutholakala khona, ngaleyo ndlela kuvinjelwe ubungozi bokushaqeka kukagesi.

Lapho ukhetha i-MCB efanelekile yohlelo lokusebenza oluthile, kubalulekile ukucabanga ngezinto ezifana nesilinganiso samanje, ukwephula umthamo nohlobo lokuvikelwa okudingekayo. Kunezinhlobonhlobo zama-MCBS atholakalayo, kufaka phakathi ama-RCBOs (amakhefu wesifunda asele akhona anokuvikelwa ngokweqile) nama-ELCBS (ukuvuza amakhompiyutha amanje), futhi kubalulekile ukukhetha i-MCB efanelekile kakhulu ukuphepha okuphezulu kakhulu kokuphepha kukagesi.

Ngamafuphi, iMCBS iyingxenye ebalulekile yokuphepha kukagesi, ukuhlinzeka ngokuvikelwa okuthembekile ekulweni okuphezulu, amaphutha okuvuthwa kwamaphutha kanye namaphutha okuvuza. Ngezinketho zalo ezahlukahlukene kufaka phakathi i-AC DC Residial yamanje 1p 2p 3p 4p MCB, RCCB, RCBBO kanye ne-ELCB, i-MCB ihlinzeka ngezixazululo eziguquguqukayo nezisebenzayo zokuvikela izinhlelo zikagesi ezinhlelweni ezahlukahlukene. Ukuqonda ukubaluleka kwama-MCBS kubalulekile ekuqinisekiseni ukuphepha nokwethenjwa kwama-Electronicalinstations.
