Imashini igabanya umuvuduko w'amashanyarazi (RCBO) ifite uburinzi bw'umuvuduko ukabije: kugenzura umutekano w'amashanyarazi
Mu ngo zigezweho, amashanyarazi ni igice cy'ingenzi cy'ibikorwa byacu bya buri munsi. Ariko, kubera ko gukoresha ibikoresho byinshi by'amashanyarazi bitera kwiyongera kw'imizigo y'amashanyarazi, ibibazo by'umutekano nabyo biravuka. Aha niho hagaragara ikibazoicyuma gihagarika umuriro gisigara gifite uburinzi bw'umuvuduko ukabije (RCBO)bishyirwa mu bikorwa, bikingira ingaruka zishobora guterwa n'amashanyarazi.
RCBO, izwi kandi nka residual current devices (RCD), ikoresha ikoranabuhanga rigezweho mu kurinda amakosa abiri asanzwe y'amashanyarazi icyarimwe: residual current na overload. Residual current iterwa n'amakosa ya circuit kandi ishobora gutera amashanyarazi cyangwa inkongi. Gushyiramo ibintu byinshi bibaho iyo umutwaro kuri circuit urenze ubushobozi bwayo ntarengwa, bigatera ubushyuhe bwinshi n'imikorere migufi.
ItsindaRCBOIkora nk'igikoresho cyo kugenzura cyihuse kandi ikagabanya amashanyarazi mu buryo bwikora iyo habonetse ikibazo. Inshingano yayo nyamukuru ni ukumenya ubusumbane buri hagati y'umuyoboro w'amashanyarazi usohoka n'umuyoboro w'amashanyarazi ugaruka muri circuit. Iyo ibonye umuyoboro w'amashanyarazi usohoka, nubwo waba muto nka milliamps nke, izahita igwa muri circuit, ikarinda impanuka z'amashanyarazi. Byongeye kandi,RCBOirinda ibintu biremereye cyane binyuze mu kuzimya urujya n'uruza rw'amashanyarazi mu buryo bwikora iyo umuyoboro w'amashanyarazi urenze urugero rwagenwe mu gihe runaka.
Imwe mu nyungu zo gukoreshaRCBOni ubushobozi bwayo bwo kumenya neza ndetse n'ingano nto y'amashanyarazi asigaye. Ibi bituma igira akamaro cyane mu gukumira impanuka y'amashanyarazi, cyane cyane mu bice bifite amazi nko mu bwiherero no mu gikoni. Byongeye kandi, ubushobozi bwayo bwo gukurikirana no kugenzura uburemere bw'amashanyarazi butuma iba igisubizo cyiza ku ngo zifite ibikoresho byinshi by'amashanyarazi.
Ikindi kintu cy'ingenzi cyaRCBOni uburyo ihura n'uburyo butandukanye bw'amashanyarazi. Byaba ari ahantu ho gutura, ubucuruzi cyangwa inganda,RCBOishobora gushyirwa mu bikorwa remezo by'amashanyarazi bisanzweho byoroshye. Imiterere yayo mito n'uburyo bworoshye bwo kuyishyiraho bituma iba amahitamo yoroshye yo kuyishyiraho no kuyivugurura.
Muri make,ibyuma bigabanya umuvuduko w'amashanyarazi (RCBOs) bifite uburinzi bw'umuvuduko ukabijeni ingenzi mu kurinda umutekano w'amashanyarazi mu ngo zigezweho. Ubushobozi bwayo bwo kumenya umuriro usigaye no gukumira umuvuduko mwinshi bituma iba igisubizo cyizewe kandi cyiza. Dukoresheje ubu buryo bw'ikoranabuhanga bugezweho mu by'amashanyarazi, dushobora kugabanya ibyago by'impanuka z'amashanyarazi no guteza imbere ibidukikije birangwamo umutekano.
