I-Moulded Case Circuit Breaker: Ithuluzi lokuvikela elihlakaniphile lezinhlelo zikagesi zezimboni

Ama-Breaker Esekethe Ahlanganisiwe: Ukuqinisekisa Ukuphepha Kukagesi

Ama-Moulded Case Circuit Breakers (MCCB) ayizingxenye ezibalulekile ezinhlelweni zikagesi ezenzelwe ukuvikela kuma-overcurrent kanye nama-short circuits. Lawa madivayisi adlala indima ebalulekile ekuqinisekiseni ukuphepha nokuthembeka kokufakwa kukagesi ezindaweni ezahlukahlukene, okuhlanganisa izindawo zokuhlala, zezentengiselwano kanye nezezimboni.

Esinye sezici ezibalulekile ze-MCCB yikhono layo lokuhlinzeka ngokuvikelwa kokusebenzisa ngokweqile kanye nokwe-short-circuit. Uma ugesi osesekethe uba phezulu kakhulu, i-MCCB iyakhubeka ngokuzenzakalelayo, iphazamise ukuhamba kukagesi futhi ivimbele umonakalo ohlelweni lukagesi kanye nemishini exhunyiwe. Lesi sici sibalulekile ekuvimbeleni imililo kagesi kanye nezinye izingozi ezingabangelwa izimo zogesi ongaphezu kwamandla.

I-MCCB nayo yenzelwe ukuba iqine, ithembeke futhi ikwazi ukumelana nobunzima bokusebenza kwansuku zonke. Ukwakhiwa kwezindlu ezibunjiwe kunikeza izinga eliphezulu lokuvikelwa kwezingxenye zangaphakathi, okuqinisekisa ukuthi i-circuit breaker ingasebenza kahle ezindaweni ezinzima. Ngaphezu kwalokho, ama-MCCB amaningi aklanyelwe ukuba angabi nokugcinwa, okunciphisa isidingo sokuhlolwa nokugcinwa njalo.

I-MCCB inikeza ukuguquguquka kanye nokulula kokusetshenziswa ekufakweni nasekusebenzeni. Lawa ma-circuit breaker atholakala ngobukhulu obuhlukahlukene kanye nokucushwa ukuze ahlangabezane nezidingo ezahlukene ze-voltage kanye nezamanje. Angafakwa kalula kuma-switchboards kanye nama-switchboards, ahlinzeka ngesisombululo esilula nesonga isikhala sokuvikela i-circuit.

Ngaphezu kwalokho, ama-MCCB anamuhla avame ukuba nezici ezithuthukisiwe ezifana nezilungiselelo zohambo ezilungisekayo, ukuvikelwa kwamaphutha omhlaba kanye namakhono okuqapha kude. Lezi zici ezengeziwe zithuthukisa ukuphepha nokusebenza kwezinhlelo zikagesi, okuvumela ukuvikelwa okwenziwe ngokwezifiso kanye nokutholwa kwamaphutha okuthuthukisiwe.

Ngamafuphi, ama-molded case circuit breakers ayingxenye ebalulekile yezinhlelo zikagesi, ahlinzeka ngokuvikelwa okudingekayo kokusebenzisa ugesi ngokweqile kanye nokusetshenziswa kwe-short-circuit. Ukwakhiwa kwawo okuqinile, ukuthembeka kanye nezici ezithuthukisiwe kwenza kube yinto ebalulekile ekuqinisekiseni ukuphepha kukagesi nokuvimbela izingozi ezingaba khona. Kungakhathaliseki ukuthi kusezindaweni zokuhlala, kwezentengiselwano noma kwezimboni, ama-MCCB adlala indima ebalulekile ekuvikeleni ukufakwa kukagesi nokunikeza abasebenzisi ukuthula kwengqondo.
