Urufunguzo rwo kurinda ibikoresho by'amashanyarazi n'umutekano w'abakozi: uruhare n'ishyirwa mu bikorwa rya RCBO

Umutwe wa Blog: Akamaro kaRCBOmu mutekano w'amashanyarazi

Mu rwego rw'umutekano w'amashanyarazi, hari ibikoresho byinshi bitandukanye bikoreshwa mu kurinda abantu n'imitungo ingaruka z'ibiza by'amashanyarazi. RCBO (imashini igabanya ubushyuhe bw'amashanyarazi irimo uburinzi bw'umuvuduko ukabije) ni kimwe muri ibyo bikoresho. Iki gikoresho kigira uruhare runini mu gukumira inkongi z'amashanyarazi, impanuka y'amashanyarazi, n'ibindi bintu bishobora guteza akaga. Muri iyi blog, tuzaganira ku kamaro ka RCBO mu mutekano w'amashanyarazi n'impamvu kigomba kuba igice cy'ingenzi cy'uburyo ubwo aribwo bwose bw'amashanyarazi.

Ubwa mbere, RCBOs zagenewe kumenya no guhagarika vuba amashanyarazi iyo hagaragaye ikibazo cy’uruziga. Ibi bishobora guterwa n’ubushyuhe bwangiritse, guhura n’amazi, cyangwa ikibazo cy’amashanyarazi gitera kuva. RCBO irinda umutekano w’abantu ku giti cyabo n’uw’umutungo wayo ihagarika amashanyarazi vuba kandi ikarinda ibyago byo gushotorana n’inkongi y’umuriro w’amashanyarazi.

Indi nyungu ikomeye ya RCBO ni ubushobozi bwo kurinda umuvuduko mwinshi. Ibi bivuze ko igikoresho gishobora no kumenya igihe hari umuvuduko mwinshi mu muvuduko, ushobora guterwa n'umuvuduko mwinshi. Muri iki gihe, RCBO izaca amashanyarazi, ikarinda ubushyuhe bwinshi n'ibyago bishobora gutera inkongi. Iki kintu ni ingenzi cyane mu ngo no mu bucuruzi aho ibikoresho byinshi by'amashanyarazi bikoreshwa icyarimwe.

Byongeye kandi, RCBO zitanga uburinzi bwo hejuru kurusha ibyuma bisanzwe bigabanya umuriro n'amasasu. Nubwo ibyuma bigabanya umuriro n'amasasu bifasha mu kurwanya imiyoboro myinshi y'amashanyarazi n'amasasu magufi, ntabwo bitanga uburinzi bw'amashanyarazi asigaye. Ku rundi ruhande, RCBO ishobora kubona n'amazi magufi agera kuri 30mA no gufata ingamba zihuse zo guhagarika umuriro. Ibi bituma RCBO ziba igice cy'ingenzi mu gushyiraho amashanyarazi agezweho, kuko ibyago byo gucika kw'amashanyarazi bibaho buri gihe.

Uretse kuba zifite imikorere yo kurinda, RCBO zoroshye kuzishyiraho no kuzibungabunga. Zishobora kongera gushyirwa mu buryo bw'amashanyarazi busanzweho kandi zikenera gusanwa gake cyane iyo zimaze gushyirwaho. Ibi bituma ziba igisubizo gihendutse cyo kongera umutekano w'amashanyarazi hatabayeho guhindura byinshi mu bikorwa remezo bihari.

Ni ngombwa kumenya ko RCBO zigomba gushyirwaho n'umuhanga mu by'amashanyarazi, kuko gushyiraho no gupima neza ari ingenzi cyane kugira ngo zigire akamaro. Ni byiza kandi kugenzura buri gihe RCBO kugira ngo harebwe imikorere yayo n'uburyo ikora neza. Ibi ni ingenzi cyane cyane mu nyubako zishaje cyangwa ahantu hashobora kuba hari amashanyarazi akomeye.

Muri make, RCBO ni igice cy'ingenzi mu kurinda umutekano w'amashanyarazi kandi zigomba gufatwa nk'igice cy'ingenzi cy'ikoranabuhanga iryo ari ryo ryose ry'amashanyarazi. Ubushobozi bwayo bwo kumenya umuriro usigaye, gutanga uburinzi bw'umuvuduko ukabije no gutanga umutekano wo hejuru kurusha ibikoresho bisanzwe byo kurinda uruziga bituma iba ishoramari ry'agaciro mu bikorwa byo mu ngo, mu bucuruzi no mu nganda. Dushyize RCBO mu bikorwa by'amashanyarazi, dushobora kugabanya cyane ibyago by'impanuka z'amashanyarazi no gushyiraho ibidukikije bitekanye kuri buri wese.
