Sobanukirwa icyo MCB isobanura n'uruhare rwayo mu by'amashanyarazi (1)

Ingingo ya mbere: MCB ni iki

MCB, izwi kandi nkaakamashini gato k'itumanaho, ni ntoyaakamashini gakoresha urujya n'uruza rw'amashanyaraziIbyo bigira uruhare runini mu buryo bw'amashanyarazi. Bitandukanye na fiyuzi zisanzwe, MCB zishobora kongera gukoreshwa, zigatanga uburinzi burushijeho kugaragara ku makosa y'amashanyarazi aterwa no kurenza urugero rw'amashanyarazi cyangwa imiyoboro migufi. Imiyoboro mito igabanya amashanyarazi igenzura umutekano n'ubwirinzi bw'ibikoresho by'amashanyarazi binyuze mu kugenzura imikorere y'amashanyarazi mu buryo bw'intoki cyangwa mu buryo bwikora.

Ishusho ya kabiri: Uburyo MCB ikora

Ihame ry'imikorere ya MCB rishingiye ku buryo bwo gutinda kwa magnetique y'ubushyuhe. Iyo amashanyarazi atembera muri MCB, imbaraga za magnetique zirakorwa. Iyo amashanyarazi ageze ku gaciro kagenwe, MCB ihita igwa igahagarika uruziga. Byongeye kandi, ibintu bishyuha muri MCB bireba impinduka z'ubushyuhe. Iyo ubushyuhe burenze agaciro kagenwe, MCB izongera kugwa, ikabuza uruziga gushyuha cyane.

Igitekerezo cya Gatatu: Ubwoko bwa Miniature Circuit Breakers

MCB ziboneka mu buryo butandukanye hashingiwe ku muvuduko wazo, nka 6A, 32A, 64A, nibindi. Zishyirwa mu byiciro hashingiwe ku mubare w'inkingi zifite, kuva kuri unipolar, bipolar, kugeza ku miterere ya mpande eshatu. Byongeye kandi, ubushobozi bwo kugabanya uburebure bw'imashini ntoya zigabanya uburebure nazo ziratandukanye, harimo 4KA, 6KA, 8KA, nibindi.

Ingingo ya kane: Ibyiza bya MCB

MCB zitanga ibyiza byinshi ugereranyije na fuse zisanzwe. Ubwa mbere, miniature circuit breakers ni nto, zoroshye, kandi zoroshye gushyiraho no gusimbuza. Imiterere yazo nto ituma ziba nziza cyane mu gushyiraho amashanyarazi agezweho. Icya kabiri, miniature circuit breakers zishobora kongera gukoreshwa inshuro nyinshi, bigatuma zihendutse kandi zikora neza. Bitandukanye na fuse, zigomba gusimburwa nyuma yo gutsindwa, MCB zishobora kongera gukoreshwa gusa, bigatuma zigabanya igihe n'umutungo.

Byongeye kandi, MCB itanga umutekano n'ubwirinzi burushijeho kwiyongera. Ishobora guhagarika urujya n'uruza rw'amashanyarazi mu buryo bwikora cyangwa mu buryo bwikora iyo bibaye ngombwa, ikarinda kwangirika cyangwa ibintu bishobora guteza akaga. Iyo ikoze vuba, MCB ifasha ko urujya n'uruza rw'amashanyarazi ruhagarara vuba, ikarinda ibikoresho by'amashanyarazi kwangirika.
