Imashini zometse kumashanyarazi ni ibikoresho byo gukingira amashanyarazi bigenewe kurinda amashanyarazi amashanyarazi adakabije.Uyu muyoboro ukabije urashobora guterwa nuburemere burenze cyangwa umuzunguruko mugufi.Imashini zashizweho zumuzunguruko zirashobora gukoreshwa mugice kinini cyumubyigano hamwe numurongo hamwe nibisobanuro byo hepfo no hejuru byurugero rwurugendo rushobora guhinduka.Usibye uburyo bwo gutembera, MCCBs irashobora kandi gukoreshwa nkintoki zo guhagarika intoki mugihe habaye ibikorwa byihutirwa cyangwa kubungabunga.MCCBs irasuzumwa kandi ikageragezwa kurenza urugero, kwiyongera kwa voltage, no kurinda amakosa kugirango habeho umutekano muke mubidukikije no mubisabwa.Bakora neza nkuburyo bwo gusubiramo amashanyarazi kugirango bahagarike ingufu kandi bagabanye ibyangiritse biterwa numuzigo urenze urugero, ikosa ryubutaka, imiyoboro migufi, cyangwa mugihe amashanyarazi arenze imipaka iriho.
MCCB cyangwa fuse nikintu cyamashanyarazi gikunze gukoreshwa muruganda kurinda ibikoresho na sisitemu.Mubuzima bwa buri munsi, MCCB ikoreshwa cyane.Porogaramu zimwe zisanzwe za MCCB zasobanuwe hano hepfo.
1.Gukwirakwiza ingufu: MCCB irashobora gufasha abayishiraho gukwirakwiza imizigo ya gride kubikoresho bitandukanye byamashanyarazi.Binyuze muri MCCB, abayikoresha barashobora kugenzura neza ikwirakwizwa ryingufu nigihe kigezweho cya buri gikoresho.
2.Uburinzi bugufi bwo kurinda: Igikorwa nyamukuru cya MCCB nuguhita uhagarika umuzunguruko mugihe habaye akanya gato.Ibi birinda kwangiza ibikoresho, kurekura ibintu biteye akaga nkumuriro.
3.Kwirinda kurenza urugero: Kimwe no kurinda imiyoboro ngufi, MCCB irashobora kandi kurinda ibikoresho kurenza urugero.Ibi birashobora kugerwaho mugushiraho ibyuma byumuzingi kugirango wirinde kwangirika kwamashanyarazi biterwa no kurenza ibikoresho.
4.Gukingira amashanyarazi: MCCB ikoreshwa cyane mugushakisha no kurinda amashanyarazi manini.Irashobora gukurikirana imikorere isanzwe ya generator, kumenya ibibazo no gukora sisitemu yo gukingira imashanyarazi.
5.Kwirinda imbaraga za transformateur: MCCB irashobora kubuza transformateur kurenza urugero no gukurikirana ubushyuhe burenze urugero icyarimwe.
6.Ibikoresho byimuka birinda: MCCB ikoreshwa cyane muri beto, sima na minerval.Itahura imiyoboro migufi hamwe nuburemere bwibikoresho, bityo ikarinda ibikoresho kwangirika.
Mu gusoza, MCCBs ikoreshwa cyane kandi igira uruhare runini mubice bitandukanye byamashanyarazi nubukanishi.Mugihe uhitamo MCCB, ibintu bitandukanye bigomba gusuzumwa neza kugirango harebwe umutekano n’ubwizerwe bwa sisitemu, harimo ubushobozi bwo gutwara ibintu, gukora neza, ahantu hakoreshwa, nibindi bipimo byingenzi.
