RCBO ni iki kandi ikora ite?

RCBOni impfunyapfunyo ya "overcurrent isigaye isigaye yamashanyarazi" kandi nigikoresho cyingenzi cyumutekano wamashanyarazi uhuza imikorere ya MCB (miniature circuit breaker) na RCD (igikoresho gisigaye). Itanga uburinzi bwubwoko bubiri bwamakosa yumuriro: amashanyarazi arenze kandi asigara (nanone bita leakage current).

Kumva uburyoRCBOikora, reka tubanze dusubiremo vuba ubu bwoko bubiri bwo gutsindwa.

Kurenza urugero bibaho mugihe ibintu byinshi bitembera mumuzunguruko, bishobora gutera ubushyuhe bwinshi ndetse byashoboka numuriro. Ibi birashobora kubaho kubwimpamvu zitandukanye, nkumuzunguruko mugufi, umutwaro urenze urugero, cyangwa amakosa yumuriro. MCBs zagenewe gutahura no guhagarika ayo makosa arenze ukandagira uruziga ako kanya iyo ikigezweho kirenze imipaka yagenwe.

Kurundi ruhande, ibisigisigi bisigaye cyangwa kumeneka bibaho mugihe umuzunguruko uhagaritswe kubwimpanuka kubera insinga mbi cyangwa impanuka ya DIY. Kurugero, urashobora guhita utobora ukoresheje umugozi mugihe ushyiraho ifoto yifoto cyangwa ukayikata hamwe na nyakatsi. Muri iki gihe, amashanyarazi ashobora gutembera mubidukikije, bishobora gutera amashanyarazi cyangwa umuriro. RCDs, izwi kandi ku izina rya GFCIs (Ground Fault Circuit Interrupters) mu bihugu bimwe na bimwe, yashizweho kugira ngo imenye vuba n’umuvuduko w’iminota ndetse no kuzenguruka umuzenguruko muri milisegonda kugira ngo hatabaho ingaruka mbi.

Noneho, reka turebe neza uburyo RCBO ihuza ubushobozi bwa MCB na RCD. RCBO, kimwe na MCB, yashyizwe muri switchboard cyangwa igice cyabaguzi. Ifite moderi yubatswe muri RCD ihora ikurikirana ikigezweho kinyura mumuzunguruko.

Iyo habaye amakosa arenze urugero, igice cya MCB cya RCBO kimenya umuyaga mwinshi kandi ukazenguruka umuzunguruko, bityo bigahagarika amashanyarazi kandi bikarinda akaga ako ari ko kose kajyanye no kurenza urugero cyangwa umuzunguruko muto. Mugihe kimwe, yubatswe muri RCD module ikurikirana uburinganire buri hagati yinsinga nzima kandi zidafite aho zibogamiye.

Niba hari ibisigisigi bisigaye byamenyekanye (byerekana amakosa yamenetse), RCD ya RCBO ihita izenguruka umuziki, bityo igahagarika amashanyarazi. Iki gisubizo cyihuse cyemeza ko amashanyarazi yirindwa kandi umuriro ushobora gukumirwa, bikagabanya ibyago byamakosa cyangwa kwangirika kwimpanuka.

Birakwiye ko tumenya ko RCBO itanga uburinzi bwumuzunguruko, bivuze ko irinda imiyoboro yihariye mu nyubako itigenga, nkumuriro cyangwa amatara. Uku kurinda modular gutuma intego yo kumenya no kwigunga, kugabanya ingaruka ku zindi nzitizi iyo habaye amakosa.

Mu ncamake, RCBO (ibisigisigi birenze urugero byumuvuduko wumuzunguruko) nigikoresho cyingenzi cyumutekano wamashanyarazi uhuza imikorere ya MCB na RCD. Ifite amakosa arenze urugero hamwe nibikorwa bisigaye byo kurinda umutekano kugirango umutekano wawe bwite kandi wirinde ingaruka z’umuriro. RCBOs igira uruhare runini mukubungabunga umutekano wamashanyarazi mumazu, inyubako zubucuruzi n’ibidukikije byinganda mukuzenguruka byihuse mugihe hagaragaye amakosa.
