MCCB: ubushobozi bwo kugabanya umuvuduko mugufi (limit limit circuit breaking capacity)

Iyo uhisemoimashini ikoresha icyuma gicana urukuta (MCCB) kuri sisitemu yawe y'amashanyarazi, ugomba kwitondera ibintu byinshi by'ingenzi. Imwe muri izi miterere ni ubushobozi bwo kugabanya umuvuduko mugufi. Iyi miterere ni ingenzi cyane mu kurinda umutekano no kwizerwa kw'imikoreshereze y'amashanyarazi, kandi ni ngombwa gusobanukirwa akamaro kayo mu gihe uhitamo MCCB.

Ubushobozi bwo gucika burundu k'umuyoboro mugufi bugaragaza urwego ntarengwa aho umuyoboro mugufi ushobora gucika burundu k'umuyoboro mugufi mu buryo butekanye mu bihe byagenwe. Iki kintu ni ingenzi cyane mu kurinda sisitemu z'amashanyarazi ingaruka zishobora kwangiza z'amakosa y'umuyoboro mugufi. Nyuma y'igeragezwa ryagenwe, umuyoboro mugufi ugomba kuba ushobora gukomeza gutwara umuyoboro mugufi mu bihe ibyo ari byo byose. Ibi bituma sisitemu y'amashanyarazi ikomeza gukora nubwo haba hari ikibazo cy'umuyoboro mugufi.

Uretse ubushobozi bwo gucika burundu kw'amashanyarazi, ubushobozi bwo gucika burundu kw'amashanyarazi bw'icyuma gicana umuriro kigizwe n'ibikoresho byabumbwe nabwo bugomba kwitabwaho. Ibi bivuga ubushobozi bwo gucika burundu mu bihe byagenwe. Ni ngombwa kumenya ko icyuma gicana umuriro kigomba gukomeza gutwara umuriro wacyo nyuma yo gukurikiza inzira z'ibizamini byagenwe. Iyi miterere ni ingenzi mu kwemeza ko sisitemu z'amashanyarazi zihamye kandi zitekanye mu gihe kirekire.

Ni ngombwa kumenya ko inganda nyinshi zikora ibikoresho byo gufunga imiyoboro y'amashanyarazi mu ngo muri iki gihe zitanga ibikoresho byo gufunga imiyoboro y'amashanyarazi bya pulasitiki bifite ubushobozi bwo gufunga imiyoboro y'amashanyarazi ku rwego rumwe rw'umuyoboro w'amashanyarazi. Ibi bituma abakoresha bahitamo ibikoresho byo gufunga imiyoboro y'amashanyarazi bihuye neza n'ibyo bakeneye n'ibyo bakeneye. Mu gihe uhitamo ibikoresho byo gufunga imiyoboro y'amashanyarazi byabumbwe, ni ngombwa kwemeza ko ubushobozi bwo gufunga imiyoboro y'amashanyarazi buhagije ku muyoboro w'amashanyarazi utegerejwe. Ibi bikuraho ko hakenewe kongeramo ibintu by'ubwishingizi mu buryo bw'ubukorano, bishobora gutuma habaho imyanda idakenewe.

Agaciro k'ubushobozi bwo gufunga amashanyarazi mu buryo buciriritse bushobora gutandukana, aho inyinshi mu mashini zifunga amashanyarazi zitanga ubushobozi buri hagati ya 25% na 75% by'ubushobozi bwo gufunga amashanyarazi mu buryo buciriritse. Hari n'izi mashini zifunga amashanyarazi zitanga 100% by'ubushobozi bwo gufunga amashanyarazi mu buryo buciriritse. Ni ngombwa gusuzuma izi ndangagaciro witonze mu gihe uhitamo MCCB kuko zigira ingaruka ku buryo butaziguye ku kwizerwa no ku mikorere y'amashanyarazi.

Muri make, ubushobozi bwo gufunga uruziga rugufi ni ikintu cy'ingenzi kigomba kwitabwaho cyane mu gihe uhitamo MCCB y'amashanyarazi yawe. Mu gusobanukirwa akamaro k'uyu mutungo n'ingaruka zawo ku mutekano no kwizerwa kw'amashanyarazi, ushobora gufata icyemezo gisobanutse neza mu gihe uhitamo MCCB ihuye neza n'ibyo ukeneye n'ibyo ukeneye. Kubera amahitamo menshi aboneka mu nganda zikora amashanyarazi zo mu rugo, ni ngombwa gusuzuma witonze ubushobozi bwo gufunga uruziga rugufi rw'amashanyarazi atandukanye kugira ngo umenye neza ko uhisemo uburyo bujyanye neza n'amashanyarazi yawe.
