Imikorere n'Itandukaniro hagati ya MCB na RCCB

GusobanukirwaMCBnaRCCB: Ibintu by'ingenzi bigize umutekano w'amashanyarazi

Umutekano ni ingenzi cyane mu gushyiraho amashanyarazi. Imashini ntoya zigabanya umuvuduko w'amashanyarazi (MCB) n'izigabanya umuvuduko w'amashanyarazi (RCCB) ni ibice bibiri by'ingenzi mu kurinda umutekano w'amashanyarazi. Ibi bikoresho byombi bifite imikoreshereze itandukanye ariko akenshi bikoreshwa hamwe kugira ngo bitange uburinzi bwuzuye ku makosa y'amashanyarazi. Iyi nkuru irasuzuma imikorere, itandukaniro, n'imikoreshereze ya za miniature circuit breakers (MCB) n'izigabanya umuvuduko w'amashanyarazi (RCCB), igaragaza akamaro kazo mu buryo bw'amashanyarazi bugezweho.

MCB ni iki?

Akamashini gato ko gukata amashanyarazi (MCB) ni agakoresho kigenga gakoreshwa mu kurinda amashanyarazi kurenza urugero n'imiyoboro migufi. Iyo umuyoboro unyura mu ruziga urenze urugero rwagenwe, MCB iragwa, igahagarika umuyoboro w'amashanyarazi. Ibi birinda kwangirika kw'ibikoresho by'amashanyarazi kandi bikagabanya ibyago by'inkongi ziterwa no gushyuha cyane kw'insinga.

Utwuma duto tw’amashanyarazi (MCB) dupimwa hakurikijwe imbaraga z’amashanyarazi bitewe n’ubushobozi bwatwo bwo gutwara umuriro, ubusanzwe kuva kuri 6A kugeza kuri 63A. Twagenewe kongera gukoresha intoki nyuma yo kugwa, ni amahitamo yoroshye ku buryo bw’amashanyarazi bwo mu ngo no mu bucuruzi. Ni ingenzi cyane mu kurinda uduce duto, nko kumurikira, gushyushya, n’aho amashanyarazi asohokera, kugira ngo uruziga rumwe rudakora ingaruka ku buryo bwose bw’amashanyarazi.

RCCB ni iki?

Imashini igabanya ubushyuhe bw'amashanyarazi (RCCB), izwi kandi nka "residual current device" (RCD), yagenewe kurinda amakosa yo ku butaka n'ihungabana ry'amashanyarazi. Imenya ubusumbane hagati y'imashini zikora n'izidafite aho zibogamiye, bushobora guterwa no kunanirwa k'ubushyuhe cyangwa gukorana n'ibice bizima ku buryo butunguranye, bigatuma amazi ava ku butaka. Iyo ubu busumbane bugaragaye, RCCB iraca inyuma ikanahagarika uruziga, bigagabanya cyane ibyago byo gushoka n'umuriro by'amashanyarazi.

RCCB ziboneka mu byiciro bitandukanye by’ubu, akenshi kuva kuri 30mA mu kurinda umuntu ku giti cye kugeza kuri 100mA cyangwa 300mA mu kurinda ibikoresho. Bitandukanye na MCB, RCCB ntizitanga uburinzi burenze urugero cyangwa uburinzi bwa "short-circuit", bityo akenshi zikoreshwa hamwe na MCB mu gushyiraho amashanyarazi.

Itandukaniro ry'ingenzi hagati ya MCB na RCCB

Nubwo MCB na RCCB byombi ari ingenzi ku mutekano w'amashanyarazi, bifite imirimo itandukanye:

1. Ubwoko bw'Uburinzi: MCB irinda umurego mwinshi n'umuvuduko mugufi mu gihe RCCB irinda ikibazo cy'ubutaka n'ihungabana ry'amashanyarazi.
2. Uburyo bwo Gukora: Imashini ntoya zikoresha amashanyarazi (MCB) zikora hashingiwe ku rugero rw'amashanyarazi, zigacika intege iyo umuriro urenze urugero rw'amashanyarazi rwagenwe. Imashini zikoresha amashanyarazi zikoresha amashanyarazi (RCCB) zikora hashingiwe ku kutagira ingano y'amashanyarazi, zigacika intege iyo hari itandukaniro hagati y'amashanyarazi asanzwe n'ay'amashanyarazi adafite aho ahuriye n'ayo.
3. Gusubiza: MCB ishobora kongera gukoreshwa n'intoki nyuma yo kugwa, mu gihe RCCB ishobora gukenera kongera gukoreshwa n'intoki nyuma yo gukemuka.

Ishyirwa mu bikorwa rya MCB na RCCB

Mu mazu no mu bucuruzi, utumashini duto dukoresha imiyoboro y'amashanyarazi (MCBs) n'utumashini dukoresha imiyoboro y'amashanyarazi (RCCBs) akenshi bikoreshwa hamwe mu kubaka uburyo bukomeye bwo kurinda amashanyarazi. Urugero, mu rugo rusanzwe, utumashini dukoresha imiyoboro y'amashanyarazi (MCBs) dushobora gushyirwa mu matara n'amashanyarazi, mu gihe utumashini dukoresha imiyoboro y'amashanyarazi (RCCBs) dushobora gukoreshwa mu bice bishobora guteza akaga nko mu bwiherero no mu gikoni, aho bishoboka ko habaho amashanyarazi menshi.

Mu nganda, MCB na RCCB ni ingenzi mu kurinda imashini n'ibikoresho amakosa y'amashanyarazi, gutuma imikorere yazo ikora neza kandi ikagabanya igihe cyo kudakora.

Mu gusoza

Muri make, utumashini duto dukoresha imiyoboro y'amashanyarazi (MCBs) n'utumashini dukoresha imiyoboro y'amashanyarazi (RCCBs) ni ingenzi mu byuma by'umutekano w'amashanyarazi. MCBs zirinda imiyoboro myinshi n'imiyoboro migufi, mu gihe RCCBs zirinda amakosa yo hasi n'amashanyarazi. Gusobanukirwa imikorere n'imikoreshereze y'ibi bikoresho ni ingenzi ku muntu wese ugize uruhare mu gushyiraho cyangwa kubungabunga amashanyarazi. Dukoresheje MCBs na RCCBs, dushobora gushyiraho ibidukikije by'amashanyarazi bitekanye, tukarinda abantu n'imitungo ibyago by'impanuka z'amashanyarazi.
