Kumena umuzunguruko usigaraho hamwe no kurindwa cyane (RCBO), mubyukuri ni ubwoko bwumuzunguruko hamwe nimikorere yo kurinda imikorere. RCBO ifite imikorere yo kurinda imikorere, amashanyarazi, kurenza urugero n'umuzunguruko mugufi. RCBO irashobora kubuza ibyifuzo byamashanyarazi kandi bifite ingaruka zigaragara kugirango wirinde impanuka zumuriro ziterwa no kumeneka kumashanyarazi. RCBOs yashizwe mumasanduku yacu isanzwe yo gukwirakwiza urugo kugirango umutekano wumuntu. RCBO nubwoko bwo kumena bihuza imikorere ya MCB na RCD muri kimwe cyo kumena umwe. Rcbos irashobora kuza muri pole 1, 1 + idafite aho abogamiye, inkingi ebyiri cyangwa inkingi ebyiri kimwe na amp igera kuri 6a kugeza kuri 100 a, rcd ubwoko bwa rcd a, a & Ac.
Ugomba gukoresha RCBO kubwimpamvu zimwe turasaba RCB - kugirango ngukize amashanyarazi yimpanuka no gukumira umuriro wamafaranga. RCBO ifite imico yose ya RCD hamwe na detector irenze urugero.
RCD ni ubwoko bwumuzunguruko wumuzunguruko bushobora guhita ukingura kumena kubamo mugihe cyisi. Uyu munwa yashizweho kugirango arengere ingaruka zo kumpanuka no kumuriro biterwa n'amakosa yisi. Amashanyarazi nayo ayita RCD (Igikoresho gisigaye) na RCCB (ibisiba birimo kumena umuzunguruko) ubu bwoko bwo kumena buri gihe bugira gusunika-buto yo kumena. Urashobora guhitamo inkingi 2 cyangwa 4, amanota ya AMP kuva 25 agera kuri 100 a, gutembera umurongo b, andika a cyangwa ac na ma rating guhera 30 ma.
Byaba byiza, byaba byiza ukoresheje ubu bwoko bwo kumena impanuka. Ibiriho iyo ari yo yose binyuze mu muntu ufite akamaro ka 30 MA irashobora gutwara umutima muri fibrililation (cyangwa guta injyana y'umutima) - ingaruka zikunze gupfa binyuze mu guhunga amashanyarazi. RCD ihagarika ubu muri milisegonda 25 kugeza kuri 40 mbere yuko amashanyarazi ashobora guhunga. Ibinyuranye, abamena usanzwe nka McB / MCCB (MCCB (miniature breaker) cyangwa fus bica gusa iyo ikiriho kirenze urugero (bishobora kuba inshuro ibihumbi Gutandukana gato no guhuza umubiri wumuntu birashobora kuba bihagije kugirango wice. Nubwo bimeze bityo, birashoboka ko bitagenda neza bihagije kugirango uhuze fuse cyangwa urenze kumena umuzunguruko kandi ntukihutire bihagije kugirango ukize ubuzima bwawe.
Itandukaniro nyamukuru hagati yabashakanye bombi ni uko RCBO ifite ibikoresho birenga. Kuri iyi ngingo, ushobora kuba utekereza kumpamvu basohora abayo niba bigaragara ko ari itandukaniro rimwe ryingenzi hagati yabo? Kuki utagurishwa ineza gusa ku isoko? Waba uhisemo gukoresha RCBO cyangwa RCD biterwa nuburyo bwo kwishyiriraho hamwe ningengo yimari. Kurugero, mugihe hariho isi yamenetse mumasanduku yo gukwirakwiza ukoresheje abahungu bose ba RCBO, gusa kumena ibintu bitanduye bizagenda. Ariko, iki giciro cyiboneza kiri hejuru kuruta gukoresha RCD. Niba bije nikibazo, urashobora gushiraho bitatu muri bine MCB munsi yikikoresho kimwe gisigaye. Urashobora kandi kuyikoresha kubisabwa byihariye nka Japuzzi cyangwa Bishyushye TUB. Ibishishwa bisaba vuba kandi bike ibikorwa byubu, muri rusange 10ma. Ubwanyuma, umworozi ushaka gukoresha biterwa nigishushanyo cyawe na bije. Ariko, niba ugiye gushushanya cyangwa uzamura ibyatsi byawe kugirango ugume mu mabwiriza no kwemeza ko amashanyarazi ari yo mutungo n'ibikoresho byombi, menya neza ko uzahura n'inzobere mu mashanyarazi yizewe.
Afdd nigikoresho cya arc igikoresho cyo gutahura amakosa kandi cyateguwe kugirango tumenye ko hariho ARC zamashanyarazi ziteye akaga no guhagarika umuzenguruko wagize ingaruka. Ibikoresho byo gutahura amakosa ya ARC bikora ukoresheje tekinoroji ya Micropropsorsor kugirango usesengure amashanyarazi. Bamenya imikono idasanzwe yasobanurwa arc kumuzunguruko. Afdd izahita ihagarika imbaraga kumuzunguruko wibasiwe neza gukumira umuriro. Barushijeho kumva arcs kuruta ibikoresho bisanzwe byumuzunguruko nka mcbs & rbcos.
