RCD, RCCB, RCBO: Ibisubizo by'umutekano w'amashanyarazi bigezweho

RCD, RCCB na RCBO: Menya itandukaniro

RCD, RCCB na RCBO byose ni ibikoresho by'ingenzi by'amashanyarazi bikoreshwa mu gukumira ibyago byo gushotorana kw'amashanyarazi n'inkongi y'umuriro. Nubwo bisa, buri gikoresho gifite intego itandukanye kandi gifite imiterere yacyo yihariye. Gusobanukirwa itandukaniro riri hagati yaRCD, RCCBnaRCBOni ingenzi cyane mu kubungabunga umutekano w'amashanyarazi mu ngo no mu bucuruzi.

RCD, mu magambo ahinnye avuga ko Residual Current Device, ni igikoresho cy’umutekano cyagenewe guca amashanyarazi vuba iyo umuriro usohoka ugaragaye mu muyoboro. Gusohoka kw'amashanyarazi bishobora guterwa n'insinga zitari zo, kwangirika kw'ibikoresho, cyangwa gukorana n'ibice bizima. RCD ni ingenzi mu gukumira impanuka y'amashanyarazi kandi zikunze gukoreshwa mu ngo, mu biro no mu nganda.

RCCB (ni ukuvuga Residual Current Circuit Breaker) ni ubwoko bwa RCD bwagenewe by’umwihariko kurinda amakosa y’ubutaka. RCCB igenzura ubusumbane bw’amashanyarazi hagati y’amashanyarazi ahoraho n’adafite aho ahuriye n’ubutaka, kandi igatera amashanyarazi iyo hagaragaye ko hari aho amazi aturuka ku butaka. Ibi bituma RCCB zigira akamaro kanini mu gukumira impanuka y’amashanyarazi iterwa n’ibibazo by’amashanyarazi.

RCBO (agakoresho gakingira umuyoboro w’amashanyarazi gasigara hamwe n’uburinzi bw’umuyoboro w’amashanyarazi urenze urugero) gahuza imirimo ya RCCB na miniature circuit breaker (MCB) mu gikoresho kimwe. Uretse gutanga uburinzi bw’ubutaka, RCBO inatanga uburinzi bw’umuyoboro w’amashanyarazi urenze urugero, bivuze ko ishobora gucika mu gihe cy’umuvuduko mwinshi cyangwa umuvuduko mugufi. Ibi bituma RCBO ziba nziza kandi zikwiriye gukoreshwa mu buryo butandukanye, harimo no kurinda imiyoboro imwe n’imwe mu miyoboro ikwirakwizwamo.

Kimwe mu bitandukanya ibi bikoresho ni uburyo bikoreshwa n'urwego rw'uburinzi bitanga. RCD zikoreshwa mu kurinda urusobe rw'amashanyarazi muri rusange, mu gihe RCCB na RCBO zikoreshwa mu kurinda urusobe rw'amashanyarazi cyangwa ibikoresho byihariye. Byongeye kandi, RCBO zifite inyungu yo kurinda umuriro mwinshi, bigatuma ziba igisubizo cyuzuye ku makosa atandukanye y'amashanyarazi.

Ku bijyanye no gushyiraho, RCD, RCCB na RCBO byagenewe gushyirwaho n'umuhanga mu by'amashanyarazi wabishoboye. Gushyiraho neza ni ingenzi kugira ngo ibi bikoresho bikore neza kandi bitange uburinzi bukenewe. Gusuzuma no kubungabunga buri gihe nabyo ni ingenzi kugira ngo RCD, RCCB na RCBO bikomeze gukora uko byari byitezwe.

Muri make, RCD, RCCB na RCBO ni ibice by'ingenzi mu byuma by'amashanyarazi bikingira umutekano, kandi buri gice gifite intego yihariye yo gukumira impanuka z'amashanyarazi n'ibyago by'inkongi. Gusobanukirwa itandukaniro riri hagati y'ibi bikoresho ni ingenzi mu guhitamo uburinzi bukwiye ku bikorwa bitandukanye. Byaba gukoresha RCD mu kurinda umutekano rusange, RCCB mu kurinda umutekano w'ubutaka, cyangwa RCBO mu guhuza uburinzi bw'ubutaka n'uburinzi bw'umuvuduko ukabije w'amazi, ibi bikoresho bigira uruhare runini mu kurinda umutekano w'amashanyarazi mu ngo no mu bucuruzi.
