RCCB MCB: Ingwate ebyiri z'amashanyarazi atagira ingaruka mbi

GusobanukirwaRCCB na MCB: Ibintu by'ingenzi bigize umutekano w'amashanyarazi

Mu isi y’amashanyarazi, umutekano ni ingenzi cyane. Ibikoresho bibiri by’ingenzi bigira uruhare runini mu kurinda umutekano w’amashanyarazi ni ibisigazwa by’amashanyarazi bisigaye (RCCBs) na bisigazwa by’amashanyarazi bito (MCBs). Nubwo byombi bikoreshwa mu kurinda imiyoboro y’amashanyarazi, bikora mu buryo butandukanye kandi byagenewe intego zitandukanye. Iyi nkuru irasuzuma byimbitse imikorere, itandukaniro, n’imikoreshereze ya RCCBs na MCBs, igaragaza akamaro kabyo mu buryo bw’amashanyarazi bugezweho.

RCCB ni iki?

RCCB (Residual Current Circuit Breaker) ni igikoresho cy’umutekano kigenzura ubusumbane bw’amashanyarazi. Cyagenewe gukumira impanuka y’amashanyarazi no kugabanya ibyago by’inkongi z’umuriro ziterwa n’ikosa ryo ku butaka. RCCB igenzura buri gihe amashanyarazi anyura mu nsinga zishyushye n’izidafite aho zibogamiye z’uruziga. Iyo ibonye itandukaniro mu amashanyarazi (bigaragaza ko amwe mu amashanyarazi arimo kuva ku butaka), iragwa ikanafungura uruziga mu masegonda make. Iki gikorwa cyihuse ni ngombwa kugira ngo abantu barindwe impanuka y’amashanyarazi no gukumira ibyago bishobora kubaho.

RCCB zikunze kugaragazwa mu byiciro bya milliamperes (mA) kandi ziboneka mu byiciro bitandukanye by’ubuhanga bwo kwirinda indwara, nka 30mA yo kwirinda umuntu ku giti cye na 100mA cyangwa 300mA yo kwirinda inkongi. Zikunze gukoreshwa mu ngo, mu bucuruzi no mu nganda, cyane cyane aho amazi ahari, nko mu bwiherero no mu gikoni.

MCB ni iki?

Ku rundi ruhande, MCB (miniature circuit breakers) zagenewe kurinda circuits kurenza urugero n'imiyoboro migufi. Bitandukanye na RCCB, zibanda ku kumenya amakosa yo hasi, MCB zigenzura amashanyarazi anyura muri circuits. Iyo amashanyarazi arenze ubushobozi bwa MCB, azacikamo urujya n'uruza kugira ngo hirindwe ubushyuhe bwinshi n'ibyago by'inkongi.

MCB zihabwa amanota muri amperes (A) kandi ziza mu bwoko butandukanye, harimo Ubwoko bwa B, Ubwoko bwa C, na Ubwoko bwa D, zagenewe kunyura mu byiciro bitandukanye by'ubushyuhe. Ubwoko bwa B burakwiriye gukoreshwa mu ngo, mu gihe Ubwoko bwa C na Ubwoko bwa D bikoreshwa mu bucuruzi n'inganda aho aba yiteze ko amazi menshi yinjira.

Itandukaniro rikomeye hagati ya RCCB na MCB

Nubwo RCCB na MCB zombi ari ingenzi ku mutekano w'amashanyarazi, zifite imirimo itandukanye:

1. Imikorere: RCCB ikoreshwa mu kurinda ikibazo cy'ubutaka n'ihungabana ry'amashanyarazi mu gihe MCB ikoreshwa mu kurinda umurego mwinshi n'umuvuduko mugufi.

2. Uburyo bwo Gutahura: RCCB imenya ubusumbane buri hagati y'imigezi ikora n'iy'imirasire idafite aho ibogamiye mu gihe MCB igenzura umugezi wose unyura mu ruziga.

3. Gukoresha: RCCB ni ingenzi mu bice bifite ibyago byinshi byo guhungabana kw'amashanyarazi, mu gihe MCB ikoreshwa mu kurinda imiyoboro y'amashanyarazi ku muvuduko ukabije w'amashanyarazi.

4. Ububasha bwo gupima: RCCB zishobora kwibasirwa n'amazi make asohoka, mu gihe MCB zo zagenewe guhangana n'amazi menshi mbere yo kugwa.

Akamaro ko gukoresha RCCB na MCB

Kugira ngo amashanyarazi abe meza, ni byiza gukoresha RCCB na MCB. Ubu buryo butanga uburinzi bwuzuye bw'ubutaka n'uburinzi bw'umubyigano. Mu buryo busanzwe bwo gushyiraho amashanyarazi, RCCB ishobora gushyirwa ku kibaho kinini cyo gusimbuza kugira ngo irinde imiyoboro yose, mu gihe MCB itandukanye ishobora gukoreshwa kuri buri miyoboro kugira ngo irinde umubyigano w'umubyigano.

Muri make, gusobanukirwa uruhare rwa RCCB na MCB ni ingenzi ku muntu wese ugize uruhare mu gushyiraho cyangwa kubungabunga amashanyarazi. Mu gushyira ibi bikoresho byombi mu buryo bw'amashanyarazi, dushobora kunoza cyane umutekano, kurengera ubuzima bw'abantu, no gukumira kwangirika kw'imitungo. Uko ikoranabuhanga rigenda ritera imbere, akamaro k'ibi bikoresho kazakomeza kwiyongera, bigatuma biba igice cy'ingenzi cy'umutekano w'amashanyarazi ugezweho.
