Itandukaniro riri hagati ya MCB na MCCB

Ku bijyanye n'ibikoresho bigabanya umuvuduko w'amashanyarazi, hari amahitamo abiri akunze gukoreshwa cyane ni MCB na MCCB. Nubwo byombi bikoreshwa mu kurinda amashanyarazi kurenza urugero ndetse no kwangirika k'amashanyarazi, hari itandukaniro rikomeye hagati y'ibyo bikoresho byombi.

Akamashini gato ko gukata uruziga (MCB), nk'uko izina ribigaragaza, ni agakoresho gato gakoresha amashanyarazi menshi. Gakoreshwa cyane ahantu hatandukanye nko mu nganda, mu bucuruzi, mu nyubako ndende, no mu ngo. MCB zagenewe kurinda ibikoresho by'amashanyarazi mu nyubako. Hari ubwoko bwinshi n'ingano y'ibikoresho bikoresha amashanyarazi, bikwiriye gukoreshwa mu buryo butandukanye.

Kimwe mu byiza by'ingenzi bya MCB ni ubushobozi bwayo bwo guhangana n'ibipimo bitandukanye by'amashanyarazi. Ikwiriye kurinda imiyoboro myinshi cyane no kurinda umuvuduko muke w'amashanyarazi hamwe na voltage ya AC 50/60Hz 230/400V n'amashanyarazi agera kuri 63A. Byongeye kandi, utumashini duto two gufunga imiyoboro dushobora no gukoreshwa mu guhinduranya imiyoboro mu buryo budasanzwe mu bihe bisanzwe. Ubu buryo bworoshye butuma iba nziza kuri sisitemu nyinshi z'amashanyarazi.

Ku rundi ruhande,imashini zica urukiramende zikozwe mu buryo bwa foromaje (MCCB) zikoreshwa cyane cyane mu buryo bwo gukwirakwiza ingufu nke za voltage no mu miyoboro y’amashanyarazi. Itanga uburinzi ku mubyimba mwinshi no ku miyoboro migufi. Ikintu nyamukuru kiranga MCCB ni agasanduku kayo ka pulasitiki, gakora nk'agakingirizo kandi kagatandukanya ibyuma n'ibyuma bicukurwa. Bitewe n'uko byizewe kandi bihamye, imiyoboro y'amashanyarazi yakoreshejwe cyane mu nganda zitandukanye.

Nubwo MCB na MCCB byombi ari imiyoboro y’amashanyarazi, hari itandukaniro rikomeye hagati yabyo. Ubwa mbere, bifite ibipimo bitandukanye by’amashanyarazi n’iby’imashini. MCB ikwiriye insinga zigera kuri metero kare 10, mu gihe MCCB ishobora guhuza insinga nini, nk’insinga ziri hejuru ya metero kare 35. Ibi bituma MCCB ibasha guhangana n’ubushobozi n’imigezi yo hejuru.

Irindi tandukaniro ni uburyo bihuzwa. Ibice by'icyuma gikoresha icyuma gifunga imiyoboro bihuzwa n'imbuto, bishobora gukanda byoroshye kandi bigatuma bikorana neza. Mu buryo butandukanye, MCB zikoresha ibice bito bikanda bishobora gukazwa gusa hakoreshejwe screwdriver. Iri tandukaniro mu buryo bwo guhuza rigira ingaruka ku gukanda no ku bwiza bw'imikorere.

Byongeye kandi, MCB na MCCB bifite ahantu hatandukanye ho gukorera. MCB zagenewe gukoreshwa mu buryo butandukanye, bigatuma zikoreshwa mu buryo butandukanye. Ku rundi ruhande, MCCB ikoreshwa cyane cyane mu buryo buciriritse bwo guhinduranya ubushobozi.

Muri make, nubwo utumashini duto dukoresha imiyoboro y'amashanyarazi n'utumashini dukoresha imiyoboro y'amashanyarazi twombi dukoreshwa mu kurinda amashanyarazi, dufite itandukaniro rikomeye. MCB ikoreshwa cyane kandi ifite uburyo bwinshi bwo kuyikoresha, mu gihe MCCB ikoreshwa cyane cyane muri sisitemu zo gukwirakwiza ingufu nkeya no muri sisitemu zo kurinda moteri. Bitandukanye mu bipimo by'amashanyarazi n'ibya mekanike, uburyo bwo guhuza n'aho bakorera. Gusobanukirwa aya tandukaniro bizafasha kumenya umuyoboro ukoresha imiyoboro y'amashanyarazi ukwiriye ibyo ukeneye byihariye.
