Umutwe: Menya itandukaniro riri hagati yaUdukingirizo duto tw'uruziganaIbice Bikoresha Uduce tw'Urugendo Bikozwe mu Kato
Utwuma dukoresha amashanyarazi ni ingenzi cyane mu nyubako. Tugufasha kurinda inzu yawe, ibiro cyangwa ubucuruzi bwawe amashanyarazi menshi cyane ndetse n'utuzu duto. Utwuma dukoresha amashanyarazi tubiri dukoreshwa cyane ni utuzu duto dukoresha amashanyarazi (miniature circuit breaker).MCB) n'icyuma gikoresha amashanyarazi cyabumbwe (MCCBNubwo byombi bifite intego imwe, hari itandukaniro hagati yabyo. Muri iyi blog, tuzasuzuma iri tandukaniro.
1. Ingano n'ikoreshwa
Itandukaniro rikomeye riri hagati yaMCBnaMCCBni ingano yazo. Nk'uko izina ribigaragaza, MCB ni ntoya kandi zikoreshwa mu bikoresho bifite ingufu nke kugeza kuri ampemetero 125. Zikunze gukoreshwa mu bikorwa byo mu ngo no mu bucuruzi buto. Ku rundi ruhande, MCCB ni nini kandi zishobora kwihanganira imbaraga nyinshi kugeza kuri ampemetero 5000. Zikunze gukoreshwa mu nganda n'ubucuruzi zisaba ingufu nyinshi.
2. Ikomeye kandi iramba
MCCB irakomeye kandi iraramba kurusha MCB. Ishobora kwihanganira amashanyarazi menshi kandi yagenewe kwihanganira ibidukikije bikomeye.MCCBakenshi bikorwa mu bikoresho bikomeye nka ceramic cyangwa pulasitiki ikoze mu buryo bwa pulasitiki kurushaMCB, ubusanzwe bikorwa mu nzu ya pulasitiki. MCB zagenewe gukoreshwa ahantu hadakomeye cyane kandi ntizigomba gushyirwa ku bikoresho byangiza cyane cyangwa ubushyuhe bukabije.
3. Uburyo bwo kunyuramo
MCB zombi naMCCBbyagenewe gucika iyo umuyoboro w'amashanyarazi urenze urugero runaka. Ariko, uburyo bakoresha mu gucika buratandukanye. MCB ifite uburyo bwo gucika amashanyarazi bukoresha ikoranabuhanga rya rukuruzi. Iyi nzira ikoresha agace ka bimetal gashyuha kandi kagahinduka iyo umuyoboro w'amashanyarazi urenze urugero runaka, bigatuma agace kagabanya umuyoboro w'amashanyarazi gacika. MCCB ifite uburyo bwo gucika amashanyarazi bukoresha microprocessor kugira ngo isesengure umuyoboro w'amashanyarazi. Iyo umuyoboro w'amashanyarazi urenze urugero, microprocessor yohereza ikimenyetso kuri circuit breaker kugira ngo icika.
4. Ikiguzi
MCBmuri rusange bihendutse kurushaMCCBIbi biterwa nuko byoroshye mu miterere kandi bikozwe mu bikoresho bihendutse. Nanone ntibiramba cyane ugereranyije na MCCB kandi bifite ubushobozi bwo gutwara umuriro muke. MCCB zirahenze cyane bitewe n'imiterere yazo igoye n'ibikoresho byakoreshejwe, ariko ziraramba cyane kandi zishobora kwihanganira imitwaro myinshi y'umuriro.
5. Kubungabunga
Ibisabwa ku kubungabunga MCB naMCCBbitandukanye cyane. MCB yoroshye mu miterere kandi ntisaba isuku nyinshi. Igomba gusuzumwa buri gihe n'umuhanga mu by'amashanyarazi hanyuma igasimburwa niba ifite ikibazo. Ku rundi ruhande, MCCB zikenera isuku nyinshi, nko kugenzura buri gihe ibikoresho by'ikoranabuhanga, bishobora gusaza uko igihe kigenda bigakenera gusimburwa.
Muri make, MCB naMCCBifite akazi kamwe, ari nako kurinda sisitemu y'amashanyarazi kurenza urugero no gufunga umuyoboro mugufi. Ariko, nk'uko tubibona, hari itandukaniro hagati yabyo byombi. MCB ni nto, ziraramba kandi zirahendutse, mu giheMCCBzikomera, ziraramba kandi zirahenze. Ikoreshwa n'ibisabwa ubu ni byo bintu by'ingenzi ugomba kuzirikana mu gihe uhitamo hagati yabyo.
