GusobanukirwaRCD, RCBOnaRCCB: Ibikoresho by'ibanze by'umutekano w'amashanyarazi
Mu isi y’umutekano w’amashanyarazi, ukunze guhura n’amagambo nka RCD, RCBO na RCCB. Ibi bikoresho bigira uruhare runini mu kurinda abantu n’imitungo amakosa y’amashanyarazi. Gusobanukirwa imikorere yabyo, itandukaniro ryabyo n’imikoreshereze yabyo ni ingenzi ku muntu wese ugize uruhare mu gushyiraho cyangwa kubungabunga amashanyarazi.
RCD ni iki?
RCD, cyangwa igikoresho cy’amashanyarazi gisigaye, ni igikoresho cy’umutekano cyagenewe gukumira impanuka y’amashanyarazi n’inkongi z’umuriro ziterwa n’ibibazo byo ku butaka. Gikora mu kugenzura buri gihe umuriro unyura mu muyoboro. Iyo kibonye ubusumbane hagati y’insinga zishyushye n’izidafite aho zibogamiye (bigaragaza ko umuriro urimo kuva ku butaka), gifungura umuyoboro mu masegonda make. Ubu buryo bwihuse bushobora kurokora ubuzima bw’abantu, bigatuma RCD ziba ingenzi mu miyoboro y’amashanyarazi yo mu ngo no mu bucuruzi.
RCD zikunze gukoreshwa mu nsinga zitanga ibikoresho byo hanze, mu bwiherero no mu gikoni aho ibyago byo guhungabana kw'amashanyarazi biri hejuru. Ziza mu buryo butandukanye, harimo RCD zigendanwa zo gushyirwamo by'agateganyo na RCD zihoraho zishyirwa mu bikoresho by'abaguzi.
RCCB ni iki?
RCCB, cyangwa se residual current circuit breaker, ni ubwoko bwihariye bwa RCD. Inshingano nyamukuru ya RCCB ni ukumenya amakosa y'ubutaka no gufungura circuit kugira ngo hirindwe impanuka y'amashanyarazi. Bitandukanye na circuit breakers zisanzwe zirinda kurenza urugero n'imiyoboro migufi, RCCB zibanda gusa ku kurinda amazi ava mu butaka.
RCCB zikunze gukoreshwa mu byuma by'amashanyarazi byo mu ngo no mu bucuruzi kugira ngo zirusheho kugira umutekano. Ziboneka mu byiciro bitandukanye, bigatuma abakoresha bahitamo igikoresho gikwiye hakurikijwe ibisabwa byihariye byo gushyiraho amashanyarazi. Nubwo RCCB zitanga uburinzi bwiza ku gushoka kw'amashanyarazi, ntizitanga uburinzi ku buremere bw'amashanyarazi cyangwa imiyoboro migufi, ari naho ibindi bikoresho bikoreshwa.
RCBO ni iki?
RCBO, cyangwa se icyuma gihagarika umuriro gisigara hamwe n’uburinzi bw’umuriro urenze urugero, bihuza imikorere ya RCD n’icyuma gihagarika umuriro. Ibi bivuze ko RCBO idakingira gusa amakosa y’ubutaka, ahubwo inarinda n’ibintu byinshi biremereye n’imiyoboro migufi. Iyi mikorere ibiri ituma RCBO iba amahitamo menshi yo gushyiramo amashanyarazi agezweho.
RCBOs ni ingirakamaro cyane cyane aho umwanya ari muto, kuko zishobora gusimbuza RCD na circuit breaker icyarimwe. Ibi ntibyoroshya gusa switchboard, ahubwo binanongera umutekano binyuze mu gutanga uburinzi bwuzuye mu gikoresho kimwe. Ni nziza cyane mu mazu yo guturamo, mu nyubako z'ubucuruzi no mu nganda.
Itandukaniro ry'ingenzi
Nubwo RCD, RCCB na RCBO zifite intego zimwe mu mutekano w'amashanyarazi, imikorere yazo iratandukanye cyane:
- RCD: Ikoreshwa cyane cyane mu kumenya amakosa yo hasi no gukuraho urusobe rw'amashanyarazi kugira ngo hirindwe impanuka y'amashanyarazi. Ntitanga uburinzi bw'amashanyarazi menshi cyangwa uburinzi bw'urusobe rw'amashanyarazi rugufi.
- RCCB: RCD yagenewe by'umwihariko gupima amakosa y'ubutaka. Kimwe na RCD, ntirinda imipaka myinshi cyangwa imiyoboro migufi.
- RCBO: Ihuza imikorere ya RCD n'icyuma gihagarika uruziga kugira ngo birinde amakosa yo ku butaka n'ibintu byinshi biremereye/ibice bigufi.
Muri make
Muri make, RCD, RCCB, na RCBO ni ibikoresho by'ingenzi mu mutekano w'amashanyarazi. Gusobanukirwa imikorere yabyo n'itandukaniro ryabyo ni ingenzi mu guhitamo uburinzi bukwiye ku buryo bw'amashanyarazi yawe. Waba uri nyir'inzu, umuhanga mu by'amashanyarazi, cyangwa umuyobozi w'ikigo, gusobanukirwa ibi bikoresho bishobora kugufasha gufata amahitamo meza no gukumira ibyago by'amashanyarazi. Mu gihe utekereza gushyiraho ibi bikoresho, buri gihe gisha inama umuhanga mu by'amashanyarazi ubifitiye ubushobozi kugira ngo urebe ko amategeko n'amahame by'aho utuye byubahirizwa.
