Imikorere n'itandukaniro riri hagati ya MCB na MCCB

GusobanukirwaMCCBnaMCBItandukaniro ry'ingenzi n'ikoreshwa

Mu bijyanye n'ikoranabuhanga ry'amashanyarazi no kurinda uruziga, amagambo abiri akunze gukoreshwa: MCB (miniature circuit breaker) na MCCB (molded case circuit breaker). Ibikoresho byombi bikora akazi k'ingenzi ko kurinda uruziga kurenza urugero n'uruziga ngufi, ariko bitandukanye cyane mu miterere yabyo, imikoreshereze, n'ubushobozi bwo gukora. Iyi ngingo igamije gusobanura itandukaniro riri hagati ya MCB na MCCB, ikagufasha gusobanukirwa igihe n'impamvu yo gukoresha buri kimwe.

MCB ni iki?

Akamashini gato ko gukata amashanyarazi (MCB) ni igikoresho gito gikoreshwa mu kurinda amashanyarazi kurenza urugero ndetse n'amashanyarazi magufi. MCB zikoreshwa mu mirimo yo mu ngo no mu bucuruzi zifite amanota make y'amashanyarazi, akenshi kuva kuri 0.5A kugeza 125A. Iyo amashanyarazi arenze urugero rwagenwe, MCB ihita igwa, ikarinda kwangirika kw'amashanyarazi n'ibikoresho bifitanye isano.

Utwuma duto dukoresha amashanyarazi (MCB) dutanga igihe cyo gusubiza vuba, ibyo bikaba ari ingenzi mu kugabanya ibyangiritse bitewe n’amakosa. Nanone dushobora kongera gusubizwa inyuma, bivuze ko iyo ikibazo kimaze gukemuka, MCB ishobora kongera gusubizwa inyuma byoroshye nta gusimbuza. Iyi mikorere ituma MCB iba amahitamo akunzwe yo kurinda ibyuma by’amatara, amashanyarazi, n’ibikoresho bito.

MCCB ni iki?

Ku rundi ruhande, MCCB zikoresha amashanyarazi yabumbwe neza kandi zigenewe gukoreshwa mu buryo buhanitse, ubusanzwe kuva kuri 100A kugeza kuri 2500A. MCCB zikunze gukoreshwa mu nganda n'ubucuruzi zifite imitwaro iremereye y'amashanyarazi. Zitanga uburinzi ku mazi menshi, ku buryo bugufi, no kurinda ikibazo cy'ubutaka, bigatuma zikoreshwa mu buryo butandukanye.

Utwuma dukoresha amashanyarazi (MCCBs) dufite uburyo bwo guhindura imiterere y’inzira, butuma abakoresha bahindura urwego rw’uburinzi hakurikijwe ibisabwa byihariye by’amashanyarazi. Iki kintu ni ingirakamaro cyane cyane mu nganda aho ibikoresho bikenerwa ubu bishobora gutandukana. Utwuma dukoresha amashanyarazi akenshi tuba dufite ibikoresho bigezweho nko kugenzura kure no gutumanaho, bikongera imikorere yabyo mu buryo bugoye bw’amashanyarazi.

Itandukaniro ry'ingenzi hagati ya MCB na MCCB

1. Ingano y'ubu**: Itandukaniro rikomeye hagati ya MCB na MCCB ni amanota yabo y'ubu. MCB ikwiriye gukoreshwa mu ikoranabuhanga rito (kugeza kuri 125A), mu gihe MCCB ikwiriye gukoreshwa mu ikoranabuhanga rito (100A kugeza 2500A).

2. Guhindura: MCB zifite imiterere y'urugendo idahinduka, mu gihe MCCB zitanga imiterere y'urugendo idahinduka, bigatuma habaho ubwisanzure bwinshi mu kurinda urujya n'uruza.

3. Imikoreshereze: MCB zikoreshwa cyane cyane mu mirimo yo mu ngo no mu bucuruzi bworoheje, mu gihe MCCB zigenewe gukoreshwa mu nganda no mu bucuruzi bukomeye, zikoresha imitwaro minini n'uburyo bugoye cyane.

4. Ingano n'igishushanyo: Utwuma duto duto (MCB) muri rusange tuba duto kandi duto kurusha utwuma duto duto (MCCB), bigatuma byoroha kubishyira ahantu hato. Utwuma duto duto (MCCB) ni tunini, dukenera umwanya munini, kandi dukunze gushyirwa mu byuma bihuza.

5. Ikiguzi: Utwuma duto duto (MCB) muri rusange turahendutse ugereranije n'utwuma duto duto, bigatuma tuba igisubizo gihendutse ku bikorwa bito. Ariko, imikorere yatwo irushaho kwiyongera n'imikorere yatwo bituma tuba ishoramari rikwiye mu bidukikije binini kandi bisaba imbaraga nyinshi.

Muri make

Muri make, utumashini duto dukoresha imiyoboro y'amashanyarazi (MCB) n'utumashini dukoresha imiyoboro y'amashanyarazi (MCCB) byombi bigira uruhare runini mu kurinda imiyoboro y'amashanyarazi, ariko uburyo bikoreshwa n'ubushobozi bwabyo biratandukanye cyane. Gusobanukirwa iri tandukaniro ni ingenzi mu guhitamo igikoresho gikwiye gikwiranye n'ibyo ukeneye byihariye. Waba uri kurinda imiyoboro mito yo guturamo cyangwa inganda nini, guhitamo umuyoboro ukwiye w'amashanyarazi bitanga umutekano, icyizere n'imikorere myiza y'ibikoresho byawe by'amashanyarazi. Buri gihe gisha inama umuhanga mu by'amashanyarazi cyangwa umuhanga mu by'amashanyarazi kugira ngo amenye igisubizo cyiza ku kibazo cyawe.
