Urupapuro rwabigenewe. Ibi byuma byumuzunguruko bihanitse bihuza uburyo bukomeye bwo kurinda hamwe nigishushanyo mbonera, gitanga uburyo bunoze bwo kwirinda amakosa y’amashanyarazi atandukanye arimo imizigo irenze urugero, imiyoboro migufi, n’amakosa y’ubutaka. MCCB zifungiwe mumazu maremare, yiziritse, MCCBs zashizweho kugirango zitange umutekano wizewe mugihe zitanga amashanyarazi meza kandi neza mumyubakire, inganda, nibigo byubucuruzi. Guhindura kwinshi kwemerera kwihinduranya binyuze muburyo bwo guhindura ingendo, bigatuma bihuza nibisabwa n'amashanyarazi atandukanye hamwe nuburyo bwo gutwara ibintu. Bitandukanye n’imashanyarazi yoroshye, MCCBs itanga ibintu byongeweho nkibikoresho byogukoresha ubushyuhe-magnetiki cyangwa ingendo za elegitoronike, ubushobozi bwo guhagarika byinshi, hamwe no guhuza neza nibindi bikoresho birinda sisitemu y'amashanyarazi. Ibi bituma ari ntangarugero mubikoresho bigezweho byamashanyarazi aho gukwirakwiza amashanyarazi yizewe no kurinda ibikoresho nibyingenzi, cyane cyane mubisabwa bisaba amashanyarazi kuva kuri amper nkeya kugeza kuri amper ibihumbi.
MCCBs zitanga uburinzi bwuzuye kurinda umuvuduko ukabije binyuze muri sisitemu ihanitse yo kurinda ibintu. Ikintu cyo gukingira ubushyuhe gikoresha umurongo wa bimetallic usubiza kumiterere irenze urugero mukunama iyo ushushe, bigatera uburyo bwo kumena. Igice cyo gukingira magnetiki gisubiza ako kanya kumuyoboro mugufi ukoresheje electromagnetic solenoid. Ubu buryo bubiri butuma habaho kurinda imitwaro buhoro buhoro no kurinda ako kanya imiyoboro ngufi, kurinda amashanyarazi n'ibikoresho bishobora kwangirika. Igenamiterere ryurugendo rushobora kwemerera abakoresha guhitamo urwego rwo kurinda rushingiye kubisabwa byihariye bisabwa, bigatuma bihinduka kubintu bitandukanye byamashanyarazi.
Kimwe mu bintu byingenzi biranga MCCBs ni igenamigambi ryurugendo rwahinduwe, ryemerera guhitamo neza ibipimo byo kurinda. Abakoresha barashobora guhindura ubushyuhe bwurugendo na magnetiki kugirango bahuze ibisabwa byumutwaro hamwe nibikenewe byo guhuza. Ihindurwa ririmo igenamigambi rirengera birenze urugero (mubisanzwe 70-100% byumuvuduko wateganijwe), igenamigambi ririnda imiyoboro ngufi, kandi rimwe na rimwe, igenamigambi ryo kurinda amakosa. MCCB igezweho ikunze kwerekana ibice byurugendo rwa elegitoronike bitanga nubushobozi bunoze bwo guhindura, harimo gutinda kwigihe hamwe nu rwego rwo gutwara, bigatuma habaho guhuza neza nibindi bikoresho birinda sisitemu y'amashanyarazi.
MCCBs zakozwe hamwe nubushobozi buhanitse bwo guhagarika, bushobora gucamo neza umutekano wamashanyarazi inshuro nyinshi urutonde rwabo. Iyi ngingo ningirakamaro mu kubungabunga umutekano wa sisitemu mugihe gikabije. Ubushobozi bwo guhagarika bushobora kuva kuri 10kA kugeza 200kA cyangwa hejuru, bitewe nurugero nibisabwa. Ubushobozi bwo kumena guhagarika imiyoboro yamakosa menshi nta byangiritse cyangwa akaga bigerwaho hifashishijwe ibyumba bizimya arc bizimya, ibikoresho byitumanaho, hamwe nuburyo bukoreshwa. Ubu bushobozi buke bwo guhagarika butuma MCCBs ikwiranye nuburinzi bwingenzi bwumuzunguruko hamwe ningirakamaro zingirakamaro zumuzunguruko aho impanuka zishobora kuba zikomeye.
Kubaka MCCBs byubatswe bitanga ubwishingizi bwiza no kurinda ibidukikije. Ibikoresho by'amazu bikoresha ubushyuhe n'amashanyarazi birinda umutekano w'abakoresha kandi bikarinda ibice by'imbere umukungugu, ubushuhe, hamwe n’imiti. Iyi myubakire ikomeye ituma MCCBs ikwiranye nuburyo butandukanye bwo kwishyiriraho, kuva ahantu h'imbere hasukuye kugeza mubihe bibi byinganda. Amazu akubiyemo kandi ibintu nka IP amanota yinzego zinyuranye zo kurengera ibidukikije n’umutungo wa flame-retardant, ukizeza igihe kirekire n’umutekano mubikorwa bitandukanye.
MCCBs ikubiyemo ibipimo byerekana neza byerekana imikorere yimena, harimo ON / OFF umwanya, urugendo rwurugendo, hamwe nubwoko bwerekana amakosa. Ibi bipimo bifasha abakozi bashinzwe kubungabunga kumenya vuba icyateye urugendo, byaba biterwa nuburemere burenze, umuzunguruko mugufi, cyangwa amakosa yubutaka. Moderi igezweho irashobora gushiramo LED yerekanwe cyangwa ibisomwa bya digitale byerekana urwego rwubu, amateka yamakosa, nandi makuru yo gusuzuma. Iyi mikorere itezimbere imikorere myiza kandi ifasha mugukemura ibibazo byamashanyarazi, kugabanya amasaha yo hasi no kunoza sisitemu yo kwizerwa.
MCCB igezweho irashobora kuba ifite ibikoresho bitandukanye byingirakamaro hamwe nibikoresho byongera imikorere yabo. Ibi birimo imfashanyo zifasha mugukurikirana imiterere ya kure, gutabaza kubimenyesha amakosa, ingendo shunt zo gutembera kure, hamwe nabakora moteri kubikorwa bya kure. Ibi bikoresho bifasha kwishyira hamwe na sisitemu yo gucunga inyubako, sisitemu ya SCADA, hamwe nubundi buryo bwo gukurikirana no kugenzura. Igishushanyo mbonera cyemerera kwishyiriraho byoroshye ibyo bikoresho, bigatuma MCCB ihuza noguhindura ibisabwa bya sisitemu nibikenewe byikora.
MCCB yateye imbere ikubiyemo imikorere yibikoresho byubushyuhe bikurikirana imiterere yubushyuhe bwumuzunguruko urinzwe na nyuma yurugendo. Iyi mikorere iremeza ko mugihe cyo kwisubiraho nyuma yurugendo rwubushyuhe, kumena kubara ubushyuhe busigaye mumuzunguruko, bikarinda kwangirika kwangirika byihuse kugera kumashanyarazi yamaze gushyuha. Imikorere yibikoresho yumuriro itezimbere kurinda neza nibikoresho kuramba urebye ingaruka ziterwa nibintu byinshi birenze urugero mugihe.
MCCB zigezweho zirimo ibice byurugendo rwa elegitoroniki byongera imbaraga zo kurinda no kugenzura ibikorwa. Ibice bishingiye kuri microprocessor bitanga ibisobanuro byukuri bigezweho hamwe no kurinda algorithm igezweho ishobora gutegurwa kubikorwa byihariye. Ibice byurugendo rwa elegitoronike bitanga ibintu nkibipimo nyabyo bya RMS, gusesengura guhuza, kugenzura ubuziranenge bwimbaraga, hamwe nubushobozi bwo kwinjiza amakuru. Barashobora kwerekana ibipimo nyabyo byamashanyarazi harimo nubu, voltage, ibintu byamashanyarazi, hamwe nogukoresha ingufu. Moderi igezweho ikubiyemo itumanaho ryitumanaho ryo kugenzura no kugenzura kure, bigafasha kwishyira hamwe na sisitemu ya gride yubwenge hamwe nuburyo bwo gucunga ingufu. Ibice byurugendo rwa elegitoronike byorohereza kandi kubungabunga ibicuruzwa hakoreshejwe isesengura riteganijwe, kugenzura uko wandikirana, no gutanga imburi hakiri kare kubibazo bishobora kuvuka, bigatuma biba ingirakamaro kuri sisitemu yo gukwirakwiza amashanyarazi agezweho.
MCCBs zakozwe hamwe nubushobozi bwubushakashatsi bwemerera kugenzura buri gihe kubungabunga bitarinze kuvanaho serivisi. Utubuto twibizamini dushoboza kugenzura uburyo bwurugendo, mugihe moderi zimwe zirimo ibyambu byipimisha byo gupima inshinge ibikorwa byo kurinda. MCCB igezweho ya elegitoronike irashobora gushiramo ibintu byo kwisuzumisha bihora bikurikirana ibice byimbere kandi bikamenyesha abakoresha ibibazo bishobora kuvuka. Ibi bikoresho byo kubungabunga byemeza imikorere yizewe kandi bifasha gukumira kunanirwa gutunguranye ukoresheje ibizamini bisanzwe no kubungabunga ibidukikije.
MCCBsbyerekana iterambere rikomeye muburyo bwa tekinoroji yo kurinda umuzunguruko, uhuza uburyo bukomeye bwo kurinda hamwe nubwubatsi bukomeye nibikorwa bitandukanye. Ibiranga ibintu byose byuzuye bituma biba ingenzi muri sisitemu y'amashanyarazi igezweho, itanga uburinzi bwizewe ku makosa atandukanye y'amashanyarazi mugihe itanga ihinduka rikenewe mubikorwa bitandukanye. Kwinjizamo igenamiterere rishobora guhinduka, ubushobozi bwo guhagarika byinshi, hamwe nubushobozi buhanitse bwo kugenzura bituma habaho uburyo bwiza bwo kurinda no kwizerwa kwa sisitemu. Hiyongereyeho ibikoresho byingirakamaro hamwe nubushobozi bwitumanaho, MCCBs zikomeje gutera imbere, zujuje ibyifuzo bya sisitemu zo gukwirakwiza amashanyarazi agezweho hamwe nubuhanga bwubaka bwubaka. Uruhare rwabo mumutekano wamashanyarazi no kurinda sisitemu bituma bagira uruhare runini mugushushanya no gukoresha amashanyarazi mumirenge yose, kuva mubikorwa byinganda kugeza kumazu yubucuruzi nibikorwa remezo bikomeye.
