MCB vs. RCCB: Uburinzi bw'Umutekano mu Cyumba cy'Umutekano

GusobanukirwaMCBnaRCCB: Ibyuma by'ingenzi by'umutekano w'amashanyarazi

Mu rwego rwo gushyiraho amashanyarazi, umutekano ni ingenzi cyane. Ibintu bibiri by'ingenzi bigira uruhare runini mu kurinda umutekano w'amashanyarazi ni Miniature Circuit Breaker (MCB) na Residual Current Circuit Breaker (RCCB). Ibi bikoresho byombi bifite intego zitandukanye ariko akenshi bikoreshwa hamwe kugira ngo bitanga uburinzi bwuzuye ku makosa y'amashanyarazi. Iyi nkuru itanga isesengura ryimbitse ku mikorere, itandukaniro, n'ikoreshwa rya MCB na RCCB, ishimangira akamaro kabyo mu buryo bw'amashanyarazi bugezweho.

Akamashini gato ko gukata uruziga ni iki?

Akamashini gato ko gukata uruziga (MCB) ni icyuma gikoresha ikoranabuhanga kirinda uruziga kurenza urugero rw'amashanyarazi n'uruziga ngufi. Iyo amashanyarazi anyura muri urwo ruziga arenze urugero rwagenwe, MCB iragwa, igahagarika amashanyarazi. Ibi birinda kwangirika kw'ibikoresho kandi bikagabanya ibyago byo gushya bitewe no gushyuha cyane kw'insinga.

Isuzuma rya MCB rishingiye ku bushobozi bwayo bwo gutwara, ubusanzwe buri hagati ya 6A na 63A. Zagenewe kongera gukoreshwa n'intoki nyuma yo kugwa, bigatuma ziba amahitamo yoroshye ku bikoresho by'amashanyarazi byo mu ngo no mu bucuruzi. MCB ni ingenzi mu kurinda imiyoboro imwe n'imwe nk'amatara, ubushyuhe n'aho amashanyarazi asohokera, kugira ngo ikibazo icyo ari cyo cyose muri iyo miyoboro imwe kitagira ingaruka ku miyoboro yose y'amashanyarazi.

RCCB ni iki?

Ibice bigabanya umuvuduko w’amashanyarazi bisigaye (RCCB), bizwi kandi nka residual current devices (RCD), byagenewe kurinda umuriro w’amashanyarazi n’inkongi z’umuriro ziterwa n’ikosa ryo ku butaka. Bipima ubusumbane hagati y’insinga zikora n’izidafite aho zibogamiye, bishobora kubaho iyo umuriro uva ku butaka, bigaragaza ko hari ikibazo gishobora kubaho. Iyo RCCB ibonye itandukaniro mu miyoboro y’amashanyarazi, iragwa mu masegonda make ikangiza uruziga, bigabanya cyane ibyago byo guhungabana k’amashanyarazi.

RCCB ziboneka mu byiciro bitandukanye, ubusanzwe kuva kuri 30mA mu kwirinda umuntu ku giti cye kugeza kuri 100mA cyangwa 300mA mu kurinda inkongi. Bitandukanye na MCB, RCCB ntizitanga uburinzi burenze urugero cyangwa uburinzi buciriritse; bityo, akenshi zikoreshwa hamwe na MCB kugira ngo zirinde umutekano wuzuye w'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 itanga uburinzi bw'umuvuduko mwinshi n'uburinzi bw'amashanyarazi, RCCB itanga uburinzi bw'ingufu z'ubutaka n'uburinzi bw'amashanyarazi.

2. Uburyo bwo Gukora: Akamashini gato gakoresha amashanyarazi gakora hakurikijwe urwego rw'amashanyarazi kandi kagatera iyo umuriro urenze urugero rw'amashanyarazi rwashyizweho. Mu buryo bunyuranye, RCCB ikora ku ihame ryo kuringaniza umuriro hagati y'insinga zikora n'izidafite aho zibogamiye.

3. Uburyo bwo gusubiza: MCB ishobora kongera gukoreshwa n'umuntu nyuma yo gusimbuka, mu gihe RCCB ishobora gukenera gusuzumwa no gukemurwa mbere yo kongera gukoreshwa.

4. Imikoreshereze: MCB zikunze gukoreshwa mu kurinda urujya n'uruza rw'amashanyarazi mu ngo no mu bucuruzi, mu gihe RCCB ari ingenzi mu bice bifite ibyago byinshi byo gushorwa n'amashanyarazi nko mu bwiherero, mu gikoni no hanze.

Akamaro ko gukoresha MCB na RCCB

Kugira ngo amashanyarazi agire umutekano mwiza, ni byiza gukoresha MCB na RCCB mu buryo butandukanye. MCB itanga uburinzi ku mubyimba mwinshi no ku muvuduko mugufi, RCCB itanga uburinzi ku mihindagurikire y'ubutaka n'ingufu z'amashanyarazi. Ubu buryo butuma sisitemu z'amashanyarazi zirindwa ingaruka zitandukanye zishobora kubaho, bityo bikongera umutekano w'abakoresha n'umutungo wabo.

Muri make, gusobanukirwa uruhare rwa MCB na RCCB ni ingenzi ku muntu wese ugize uruhare mu gushyiraho cyangwa kubungabunga amashanyarazi. Mu gushyira ibikoresho byombi mu buryo bw'amashanyarazi, ibyago byo guhura n'impanuka z'amashanyarazi bishobora kugabanuka cyane, bigatuma habaho ibidukikije bitekanye kuri buri wese. Haba mu ngo, mu bucuruzi cyangwa mu nganda, guhuza MCB na RCCB ni ingenzi mu mikorere ya none y'umutekano w'amashanyarazi.
