Mu rwego rw'umutekano w'amashanyarazi,imashini zigabanya umuvuduko w'amashanyarazi (RCCBs)bigira uruhare runini mu kurinda abantu n'imitungo ingaruka z'amashanyarazi. Ibi bikoresho byagenewe gukumira impanuka y'amashanyarazi no kugabanya ibyago by'inkongi z'umuriro ziterwa n'ikosa ryo hasi. Iyi nkuru izavuga ku mikorere, akamaro, n'ikoreshwa rya RCCB mu buryo burambuye.
Igikoresho cyo gukata amashanyarazi gikoreshwa n'amashanyarazi (RCCB) ni iki?
Imashini igabanya umuvuduko w'amashanyarazi (RCCB) ni igikoresho cy'amashanyarazi gihagarika umuvuduko w'amashanyarazi iyo kibonye ubusumbane mu muvuduko w'amashanyarazi hagati y'insinga zikora (phase) n'izitagira aho zibogamiye. Ubu busumbane bushobora guterwa n'ikosa, nko gukora ku giti cy'umuntu ku bw'impanuka ku muvuduko w'amashanyarazi, cyangwa ikosa ry'amashanyarazi rituma umuvuduko w'amashanyarazi uva hasi. RCCB ikomeza kugenzura umuvuduko w'amashanyarazi mu muvuduko w'amashanyarazi, kandi iyo ibonye itandukaniro ry'umuvuduko w'amashanyarazi (ubusanzwe ni 30 mA kugira ngo yirinde umuntu ku giti cye), irahagarika kandi igahagarika amashanyarazi mu masegonda make.
Ni iyihe ngingo ngenderwaho y'imikorere y'icyuma gikoresha amashanyarazi asigaye (RCCB)?
Akamashini gakoresha ingufu zikoreshwa mu gukwirakwiza umuriro (RCCB) gakora ku ihame ry’umuvuduko utandukanye. Kagizwe n’inkingi y’icyuma n’imirongo ibiri: imwe y’insinga ikora n’indi y’insinga itagira aho ibogamiye. Mu bihe bisanzwe, umuvuduko unyura muri za conductors ebyiri urangana, kandi imbaraga za rukuruzi zikorwa n’imirongo zirasenya. Ariko, iyo umuvuduko usohoka uhari, iri teraniro rirahungabana, bigatuma habaho itandukaniro mu mbaraga za rukuruzi. Uku kutumvikana gutuma RCCB igwa, igahagarika urujya n’uruza kandi ikarinda ibyago bishobora kubaho.
Akamaro k'ibikoresho bigabanya umuriro bikoreshwa n'amashanyarazi
Akamaro k'ibikoresho bigabanya umuriro (RCCBs) ntibikwiye kwirengagizwa. Ni inzira y'ingenzi yo kwirinda impanuka y'amashanyarazi, ishobora gutera imvune zikomeye ku muntu cyangwa urupfu. Dukurikije amahame y'umutekano, inyubako nyinshi zo guturamo n'iz'ubucuruzi, cyane cyane ahantu hari amazi (nk'ubwiherero n'ibikoni), zigomba kuba zifite ibikoresho bya RCCBs. RCCBs zishobora gusubiza vuba ibibazo by'amashanyarazi, bikanoza cyane umutekano w'ibikoresho by'amashanyarazi.
Byongeye kandi, ibyuma bigabanya umuriro bikoreshwa n’amashanyarazi (RCCBs) bifasha mu gukumira inkongi z’umuriro. Ikosa ry’imirongo, kwangirika kw’ubushyuhe, cyangwa amakosa y’amashanyarazi byose bishobora gutera ubushyuhe bwinshi n’ibishashi, bishobora gutwika ibikoresho bishobora gushya. RCCBs zishobora guhita zihagarika uruziga iyo habayeho ikosa, bityo bikagabanya ibyago byo gushya no kurinda ubuzima n’imitungo.
Gukoresha Ibice Bikoresha Umuriro Bisigaye
Utwuma dukoresha ingufu zikoreshwa n'amashanyarazi (RCCBs) dukoreshwa cyane mu bice bitandukanye, harimo n'amazu yo guturamo, ubucuruzi, n'inganda. Mu mazu yo guturamo, dukunze gushyirwa ku gice cy'ingenzi gikwirakwiza ibikoresho kugira ngo turinde uduce twose. Mu mazu y'ubucuruzi, RCCBs ni ingenzi cyane mu kurinda ibikoresho no kurinda umutekano w'abakozi n'abakiriya. Mu nganda, cyane cyane aho imashini ziremereye zikoreshwa, RCCBs ni ingenzi cyane mu kurinda abakozi ingaruka z'amashanyarazi.
Byongeye kandi, ibikoresho bigabanya umuriro bikoreshwa n’amashanyarazi (RCCBs) bishobora guhuzwa n’ibindi bikoresho birinda, nka miniature circuit breakers (MCBs) na surge protectors (SPDs), kugira ngo habeho uburyo bwuzuye bwo kurinda amashanyarazi. Ubu buryo ntibutuma gusa hamenyekana kandi hagafatwa ingamba zo gukemura ibibazo by’ubutaka, ahubwo bunakemura neza ibibazo by’amazi n’ubwiyongere bw’amazi.
Ni iki gituma umuyoboro wa RCD ugwa?
Insinga ziremereye cyane, kwinjira k'ubushuhe, insinga zangiritse, amazi ava mu butaka, n'ibikoresho bifite ikibazo ni bimwe mu bituma RCD igwa. Gusobanukirwa ibi bintu bishobora kugufasha kumenya no gukemura ikibazo vuba kugira ngo urebe ko amashanyarazi ari meza mu rugo rwawe.
Muri make
Muri make, ibyuma bigabanya ubushyuhe bw'amashanyarazi (RCCBs) ni igice cy'ingenzi cy'uburyo bugezweho bwo kurinda umutekano w'amashanyarazi. Bimenya kandi bigakemura ikibazo cy'ubusumbane bw'amashanyarazi, bikaba ibikoresho by'ingenzi mu gukumira impanuka z'amashanyarazi n'inkongi z'umuriro. Uko ubuzima bwacu bwa buri munsi bugenda bwishingikiriza ku mashanyarazi, gusobanukirwa no gukoresha RCCBs ni ingenzi mu kubungabunga umutekano mu ngo, aho bakorera n'ahandi. Gushora imari mu bikoresho byiza bya RCCBs no kwemeza ko bishyirwa neza bitanga amahoro yo mu mutima kandi bikarinda impanuka z'amashanyarazi.
