Umuhanda wa MCB utemba

Utwuma duto tw'amashanyarazi (MCB) bigira uruhare runini mu kurinda imiyoboro n'ibikoresho. Izi miniature circuit breakers zagenewe guhagarika urujya n'uruza rw'amashanyarazi mu buryo bwikora iyo hagaragaye ikosa, birinda kwangirika kw'imikorere no kurinda umutekano w'abakozi. Ikintu cy'ingenzi cya MCB ni ubwoko bw'imiyoboro y'urugendo, bugena igihe cyo gusubiza n'igipimo cy'ubu cy'imiyoboro y'uruziga iyo iguye. Gusobanukirwa ubwoko butandukanye bw'imiyoboro y'urugendo ni ingenzi mu guhitamo MCB ikwiye gukoreshwa mu buryo bwihariye.

Uburyo bwo gucika kw'icyuma gito gikoresha amashanyarazi (circuit breaker) bugaragaza isano iri hagati y'umuyoboro wa rukuruzi ukoresha amashanyarazi n'umuyoboro ukoresha amashanyarazi. Hariho ubwoko butandukanye bw'uburyo bwo gucika, buri bumwe bukwiriye ubwoko butandukanye bw'imizigo n'ikoreshwa. Ubwoko busanzwe bw'uburyo bwo gucika kw'amashanyarazi kuri MCB burimo ubwoko bwa A, ubwoko bwa B, ubwoko bwa C n'ubwoko bwa D. Buri bwoko bufite imiterere yihariye kandi bukwiriye ibintu bitandukanye, kuva ku kurinda imiyoboro ya elegitoroniki ya semiconductor kugeza aho imitwaro iremereye itangirira.

Umuyoboro wa A urangwa n'umuyoboro wa rukuruzi wa (2-3) In. Ukwiriye kurinda imiyoboro ya elegitoroniki ya semiconductor, imiyoboro yo gupima ya transfoma z'ingufu nke, cyangwa sisitemu zifite imirongo miremire n'imiyoboro mito. MCB zo mu bwoko bwa A zagenewe gutanga igisubizo cyihuse ku makosa yo ku rwego rwo hasi, bigatuma ziba nziza ku bikoresho by'ikoranabuhanga byoroshye n'imiyoboro ikenera uburinzi nyabwo.

Umuvuduko wa rukuruzi wo mu bwoko bwa B tripping curve ni (3-5) In. Izi MCB zikwiriye imitwaro irinda gusa no gukoresha amatara make. Zikunze gukoreshwa mu buryo bwo gukwirakwiza ingufu z'amashanyarazi mu rugo, mu bikoresho byo mu rugo no mu kurinda umutekano w'umuntu ku giti cye. MCB zo mu bwoko bwa B zitanga uburinzi bunoze ku bikorwa bitandukanye byo mu ngo no mu bucuruzi.

Umuvuduko wa rukuruzi wo mu bwoko bwa C tripping curve ni (5-10) In. Izi MCB zikwiriye imitwaro ikoreshwa mu gukurura no mu matara afite ubushobozi bwo kuzamuka cyane. Zikunze gukoreshwa mu kurinda imiyoboro y’amashanyarazi n’amatara afite imiyoboro ikoreshwa mu gukurura cyane. MCB zo mu bwoko bwa C zirakoreshwa mu buryo butandukanye kandi zikwiriye gukoreshwa mu nganda zitandukanye aho hakenewe uburinzi nyabwo bw’imizigo ikoreshwa mu gukurura.

Umuyoboro wa D urangwa n'umuyoboro wa magnetic tripping wa (10-20) In. Izi MCB zikwiriye sisitemu zifite imizigo myinshi itera imbaraga n'imiyoboro minini itera imbaraga. Zikunze gukoreshwa mu kurinda ibikoresho bifite imiyoboro myinshi itera imbaraga, nka transformers na solenoid valves. MCB zo mu bwoko bwa D zagenewe kwihanganira imizigo iremereye no gutanga uburinzi bwizewe mu nganda.

Muri make, gusobanukirwa imiyoboro y’amazi y’ubwoko butandukanye bwa miniature circuit breakers ni ingenzi cyane mu guhitamo MCB ikwiye gukoreshwa mu buryo bwihariye. Byaba kurinda imiyoboro y’amashanyarazi yoroheje cyangwa ibikoresho bikomeye by’inganda, MCB zifite ubwoko bukwiye bwa miyoboro y’amazi ni ingenzi cyane mu kwemeza umutekano n’ubwizerwe bw’imikorere y’amashanyarazi. Kubera ubushobozi bwazo butandukanye, MCB ziracyari igice cy’ingenzi mu mutekano no kurinda amashanyarazi mu nganda zitandukanye.

Mutai Group imaze imyaka irenga icumi ikora kandi igurisha mu ngandaibikoresho byo gukata urujya n'uruza, ibikoresho byo kontakti, ingufu ebyiriswichi zo kohereza amafaranga mu buryo bwikora (ATS) n'ibindi bifitanye isano. Dutegereje cyane amahirwe yo gukorana nawe.
