Ubuyobozi bwuzuye bwaUdukingirizo duto tw'uruziga
menyekanisha
Muri iki gihe cy’iterambere, amashanyarazi ni ingenzi mu buzima bwacu bwa buri munsi, agatanga ingufu mu ngo zacu, mu biro no mu nganda. Kubwibyo, kugenzura ko akwirakwizwa neza kandi mu buryo butekanye ni ingenzi cyane. Kimwe mu bintu by'ingenzi muri iki gikorwa niakamashini gato ko gukata uruziga (MCB)Muri iyi nkuru, turareba mu buryo bwimbitse isi yautumashini duto two gukata uruziga, gusuzuma imikorere yabyo, ubwoko bwabyo n'inyungu zabyo.
GusobanukirwaUdukingirizo duto tw'uruziga
A akamashini gato k'itumanahoni icyuma gikoresha amashanyarazi cyagenewe kurinda amashanyarazi kwangirika guterwa n'umuvuduko mwinshi w'amashanyarazi, umuvuduko mugufi cyangwa umutwaro mwinshi. Bitandukanye na firigo zisanzwe zigomba gusimburwa nyuma yo gucika intege,utumashini duto two gukata uruzigaishobora kongera gukoreshwa ukoresheje intoki iyo ikibazo kimaze gukemuka. Iyi mikorere ituma byoroha cyane kandi bigahendutse.
Imirimo yautumashini duto two gukata uruziga
1. Uburinzi bw'umuvuduko ukabije w'amazi:
Inshingano nyamukuru ya MCB ni ugutanga uburinzi bw'umuyoboro urenze urugero. Iyo umuyoboro urenze urugero rw'umuyoboro (bigaragaza ikibazo muri circuit), icyuma gito gihagarika amashanyarazi kiracika, kigahagarika urujya n'uruza rw'amashanyarazi. Iki gikorwa kirinda kwangirika kw'imiyoboro n'ibikoresho by'amashanyarazi bihujwe.
2. Uburinzi bw'urujya n'uruza rw'amashanyarazi:
Umuyoboro mugufi ubaho bitewe n'imikoranire itaziguye y'amashanyarazi akoresha polarite zitandukanye, bigatuma umuriro uzamuka mu buryo butunguranye. MCB ihita imenya iyi ndwara idasanzwe hanyuma igafunga umuyoboro vuba, ikarinda ibyago bishobora kubaho nko gutwika amashanyarazi no kwangirika kw'ibikoresho.
3. Uburinzi bw'umutwaro urenze urugero:
Imiyoboro ifite ubushobozi bwihariye bwo kurenza ubushobozi bwo gucika intege cyangwa kwangirika. Imiyoboro mito y’amashanyarazi yagenewe kugenzura no kurinda ubushyuhe bukabije buterwa no kurenza urugero rw’amashanyarazi. Mu kugenzura buri gihe uko umuriro ugenda, MCB zirinda imiyoboro ingaruka zishobora kubaho.
Ubwoko bwa Miniature Circuit Breakers
1. Inkingi imweakamashini gato k'itumanaho:
Unipolar MCBs zikoreshwa mu mazu. Zirinda imiyoboro y’amashanyarazi ku giti cyazo nk’amatara, amasoko n’ibikoresho. Izi MCBs zifite inkingi yo kuzimya umuriro, bivuze ko zishobora gutandukanya umuyoboro umwe gusa.
2. Inkingi ebyiriakamashini gato k'itumanaho:
BipolarMCBzikoreshwa mu bikoresho bisaba ubushobozi bwo hejuru bw'amashanyarazi. Zirinda imiyoboro ifite imitwaro iremereye, nk'ibikoresho bikonjesha cyangwa ibyuma bishyushya amazi bikoresha amashanyarazi. Bitandukanye na MCB zikoresha unipolar, MCB zikoresha bipolar zishobora gufunga insinga zikora n'izidafite aho zibogamiye, bigatuma zigumana neza.
3. Inkingi eshatuakamashini gato k'itumanaho:
Inkingi eshatuMCBzikoreshwa cyane mu nganda aho usanga ingufu z’amashanyarazi zikoresha ibice bitatu. Zitanga uburinzi ku muyoboro mugufi, kurengera umubyimba mwinshi no kutagira ingano. Izi miniature circuit breakers zirinda umutekano wa moteri z’ibice bitatu n’ibindi bikoresho bikoresha ingufu nyinshi.
Ibyiza byaUdukingirizo duto tw'uruziga
1. Umutekano wongerewe:
MCB zitanga umutekano mwinshi ugereranije na fize zisanzwe kuko zigwa mu buryo bwikora mu gihe habayeho ikosa. Ubu buryo bugabanya ibyago byo gushoka kw'amashanyarazi, inkongi y'umuriro, cyangwa kwangirika kw'ibikoresho bihenze.
2. Gusubiza byoroshye:
Bitandukanye na za fuse, zigomba gusimburwa nyuma ya buri rugendo,MCBishobora kongera gukoreshwa vuba ukoresheje intoki. Ubu buryo bworoshye buzigama umwanya n'imbaraga kandi butuma amashanyarazi agaruka vuba.
3. Imikorere y'ikiguzi:
MCBni igisubizo gihendutse kuko gishobora gukoreshwa inshuro nyinshi kidasimbuwe. Ubushobozi bwabyo bwo kugwa vuba birinda kwangirika, bigabanya ikiguzi cyo gusana cyangwa gusimbuza insinga n'ibikoresho by'amashanyarazi.
mu gusoza
Utwuma duto tw'amashanyarazibigira uruhare runini mu gukwirakwiza amashanyarazi mu buryo bwizewe kandi bunoze. Birinda ibyago bishobora kubaho no kwangirika kw'ibikoresho binyuze mu bushobozi bwabyo bwo kurinda imiyoboro y'amashanyarazi ikabije, imiyoboro migufi, n'ibintu byinshi biremereye. Biboneka mu bwoko bwinshi kandi bifite inyungu nyinshi, MCB ni igice cy'ingenzi cy'amashanyarazi yacu akoreshwa mu ngo no mu nganda.
