Gusobanukirwa MCBs (Miniature Circuit Breakers) - Uburyo bakora nimpamvu ari ngombwa mukurinda umutekano

Mwisi yisi ya sisitemu yumuriro nizunguruka, umutekano ningenzi.Kimwe mu bintu by'ingenzi bigize umutekano w’umuzunguruko no kurinda niMCB (miniature yamashanyarazi).MCBs zagenewe guhita zifunga imirongo mugihe hagaragaye ibihe bidasanzwe, bikarinda ingaruka zishobora kubaho nkumuzunguruko mugufi numuriro wamashanyarazi.

None, MCB ikora ite?Reka twinjire mubikorwa byimbere yiki gikoresho cyingenzi.Hariho ubwoko bubiri bwitumanaho imbere muri MCB - imwe irakosowe indi ikurwaho.Mubikorwa bisanzwe bisanzwe, iyi mibonano ikomeza guhura nundi, ituma imiyoboro inyura mumuzunguruko.Ariko, mugihe ikigezweho cyiyongereye kirenze ubushobozi bwagenwe bwumuzunguruko, abimuka byimuka bahatirwa guhagarika imiyoboro ihamye.Iki gikorwa "gifungura" neza umuzunguruko, guca ikigezweho no gukumira ibyangiritse cyangwa akaga gashobora kubaho.

Ubushobozi bwa MCB bwo kumenya byihuse kandi neza kumenya umuyaga ukabije no gusubiza uhita uhagarika umuzenguruko bituma biba ingenzi muri sisitemu y'amashanyarazi.Inzira ngufi ibaho mugihe hari isano itunguranye hagati yinsinga zishyushye kandi zidafite aho zibogamiye, zishobora gutera kwiyongera gutunguranye.Niba MCB idashyizweho, umuyaga mwinshi uterwa numuzunguruko mugufi urashobora gutera ubushyuhe bwinshi, gushonga ibikoresho byokwirinda, cyangwa umuriro wumuriro.Muguhagarika byihuse umuzunguruko mugihe habaye uruziga rugufi, imashanyarazi ntoya ifite uruhare runini mukurinda ibiza.

Usibye imiyoboro migufi, MCBs irinda kandi andi makosa y'amashanyarazi nko kurenza urugero no kumeneka.Kurenza urugero bibaho mugihe umuzenguruko uremerewe cyane, ushushanya ibintu byinshi cyane, kandi kumeneka bibaho mugihe hari inzira itateganijwe kubutaka, birashoboka ko byaviramo amashanyarazi.MCBs irashobora kumenya no gusubiza ayo makosa, itanga umutekano wongeyeho sisitemu y'amashanyarazi nabantu bayikoresha.

Akamaro ka MCB ntabwo kari mubikorwa byayo gusa;Ingano yoroheje kandi yoroshye yo kwishyiriraho nayo ituma ihitamo ryambere kurinda umuziki.Bitandukanye na fuse gakondo, MCBs irashobora gusubirwamo nyuma yo gukandagira, ikuraho ibikenewe gusimburwa igihe cyose habaye amakosa.Ibi ntibizigama igihe n'imbaraga gusa, ahubwo binagabanya amafaranga yo kubungabunga no gusimbuza.

Ubwanyuma, MCB nintwari zitavuzwe zumutekano wumuriro wamashanyarazi, zikora zituje inyuma yinyuma kugirango zirinde imirongo nabantu babishingiraho.MCBs irashobora gutabara vuba mubihe bidasanzwe mumuzunguruko kandi nikintu cyingenzi mukubungabunga umutekano nubusugire bwa sisitemu yamashanyarazi.Haba ahantu hatuwe, mu bucuruzi cyangwa mu nganda, kuba MCB iremeza ko amakosa y’amashanyarazi akemurwa vuba, bikagabanya ibyago byangiritse nibishobora guteza ingaruka.Mugihe ikoranabuhanga rikomeje gutera imbere, imashini zangiza za miniature ntagushidikanya ko zizakomeza kuba urufatiro rwo kurinda umuzunguruko, biguha amahoro yo mu mutima kandi bikomeza amashanyarazi.
