Imikorere n'itandukaniro riri hagati ya MCB na RCCB

GusobanukirwaMCBnaRCCB: Ibintu by'ingenzi bigize umutekano w'amashanyarazi

Umutekano ni ingenzi cyane mu isi y’ibikoresho by’amashanyarazi. Ibikoresho bito bigabanya umuvuduko w’amashanyarazi (MCB) n’ibisigazwa by’amashanyarazi bisigara (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 mu buryo bwimbitse imikorere, itandukaniro, n’imikoreshereze ya bisigazwa by’amashanyarazi bigufi (MCB) n’ibisigazwa by’amashanyarazi bisigara (RCCB), kandi igaragaza akamaro kabyo mu buryo bw’amashanyarazi bugezweho.

MCB ni iki?

Akamashini gato ko gukata amashanyarazi (MCB) ni icyuma gikoresha amashanyarazi mu buryo bwikora kigamije kurinda amashanyarazi kurenza urugero rw'amashanyarazi n'imiyoboro migufi. Iyo umuyoboro unyura mu ruziga urenze urugero rwagenwe, MCB irahungabanywa ikanahagarika amashanyarazi. Ibi birinda ubushyuhe bwinshi n'ibyago bishobora guterwa n'umuyoboro ukabije w'amashanyarazi. Umuyoboro upima agaciro ka MCB uterwa n'ubushobozi bwayo bwo gutwara umuriro, akenshi hagati ya 6A na 63A, kandi wagenewe gukora vuba kugira ngo ugabanye kwangirika kw'ibikoresho n'insinga.

Utwuma duto two gusohora amashanyarazi (MCB)ni ingenzi mu miturire, ubucuruzi, n'inganda. Akenshi zikoreshwa mu byuma bihindura amashanyarazi kugira ngo zirinde amashanyarazi ku buryo bumwe, bigatuma amashanyarazi adakora neza ku buryo bwose. Utwuma duto duhindura amashanyarazi dushobora kongera gukoreshwa, bityo amashanyarazi ashobora kugarurwa byoroshye nyuma yo gusanwa, bigatuma aba amahitamo yoroshye yo kurinda 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'insinga zikora n'izidafite aho zibogamiye, bishobora kubaho iyo insinga zikora ku buryo butunguranye cyangwa iyo impanuka ikoze ku bice bizima bigatuma umuriro ugwa ku butaka. Iyo ubu busumbane bugaragaye, RCCB iraca inyuma uruziga, bigagabanya cyane ibyago byo gucika kw'amashanyarazi n'inkongi y'umuriro.

RCCB ziboneka mu byiciro bitandukanye by’ubuhanga, ubusanzwe kuva kuri 30mA mu kwirinda umuntu ku giti cye kugeza kuri 100mA cyangwa 300mA mu kurinda ibikoresho. Guhitamo ubuhanga biterwa n’uburyo ikoreshwa n’urwego rw’ubuhanga rukenewe. Urugero, mu gace k’iwabo, RCCB ya 30mA ikoreshwa mu kurinda abantu amashanyarazi, mu gihe mu nganda, RCCB ifite ubunini bw’amashanyarazi bushobora gukoreshwa mu kurinda ibikoresho.

MCB vs RCCB: Itandukaniro ry'ingenzi

Nubwo ibicamo ibice bito (MCB) na bicamo ibice bisigara (RCCB) byombi ari ingenzi mu mutekano w'amashanyarazi, bikora imirimo itandukanye. Itandukaniro rikomeye riri mu buryo bwo kubirinda:

- MCB: Irinda umuvuduko mwinshi n'umuvuduko muke. Ntitanga uburinzi ku butaka cyangwa amashanyarazi.
- RCCB: Irinda ikibazo cy'ubutaka n'ihungabana ry'amashanyarazi. Ntitanga uburinzi bw'umubyigano cyangwa uburinzi bw'amashanyarazi magufi.

Bitewe n'iri tandukaniro, utumashini duto dukoresha amashanyarazi (MCBs) n'utumashini dukoresha amashanyarazi (RCCBs) dukunze gukoreshwa hamwe mu gushyiraho amashanyarazi. Ubu buryo butanga uburinzi bwuzuye, butuma sisitemu z'amashanyarazi n'abakoresha barushaho kugira umutekano.

Ishyirwa mu bikorwa rya MCB na RCCB

Mu mihana y’abaturage, utumashini duto dukoresha imiyoboro y’amashanyarazi (MCB) dukunze gukoreshwa mu kurinda urumuri n’amashanyarazi, mu gihe utumashini dukoresha imiyoboro y’amashanyarazi (RCCB) dushyirwa ahantu hafite ibyago byinshi byo gushorwa n’amashanyarazi kugira ngo umutekano urusheho kwiyongera, nko mu bwiherero no mu gikoni. Mu mihanda y’ubucuruzi n’inganda, ibikoresho byombi ni ingenzi mu kurinda imashini no kurinda umutekano w’abakozi.

Muri make, utumashini duto duto (MCB) n'utumashini duto duto dukoresha ingufu z'amashanyarazi (RCCB) ni igice cy'ingenzi cy'uburyo bw'umutekano w'amashanyarazi. Gusobanukirwa imikorere n'imikorere yabyo ni ingenzi ku muntu wese ugize uruhare mu gushyiraho cyangwa kubungabunga amashanyarazi. Mu guhuza utumashini duto dukoresha ingufu z'amashanyarazi (MCB) n'utumashini duto dukoresha ingufu z'amashanyarazi (RCCB), hashobora kubakwa uburyo bukomeye bwo kurinda ingaruka zitandukanye z'amashanyarazi, bigatuma habaho ibidukikije bitekanye kuri buri wese.
