Ibisigisigi byumuzunguruko bisigaye hamwe nuburinzi burenze (RCBO), mubyukuri ni ubwoko bwumuzunguruko ufite ibikorwa byo gukingira.RCBO ifite umurimo wo kurinda kumeneka, guhungabana kw'amashanyarazi, kurenza urugero n'umuzunguruko mugufi.RCBO irashobora gukumira impanuka zatewe n’amashanyarazi kandi zikagira ingaruka zigaragara zo kwirinda impanuka z’umuriro ziterwa n’umuriro w'amashanyarazi.RCBOs yashyizwe mubisanduku rusange byo gukwirakwiza murugo kugirango umutekano wabantu ugerweho.RCBO ni ubwoko bwa breaker ihuza imikorere ya MCB na RCD muburyo bumwe.RCBOs irashobora kuza muri pole 1, 1 + idafite aho ibogamiye, inkingi ebyiri cyangwa inkingi 4 kimwe hamwe na amp amanota kuva 6A kugeza kuri 100 A, gutembera umurongo B cyangwa C, Kumena ubushobozi 6K A cyangwa 10K A, Ubwoko bwa RCD A, A & A AC.
Ugomba gukoresha RCBO kubwimpamvu zimwe dusaba RCB - kugukiza amashanyarazi atunguranye no gukumira umuriro w'amashanyarazi.RCBO ifite imico yose ya RCD hamwe na detector ikabije.
RCD ni ubwoko bwumuzunguruko ushobora guhita ufungura icyuma mugihe habaye amakosa yisi.Iyi breaker yashizweho kugirango irinde ingaruka ziterwa namashanyarazi nimpanuka zatewe namakosa yisi.Abanyamashanyarazi nabo babyita RCD (Igikoresho gisigaye cyubu) na RCCB (Ibisigisigi byubu byumuzunguruko) Ubu bwoko bwa breaker burigihe bufite buto-buto yo gukora ikizamini.Urashobora guhitamo kuva kuri 2 cyangwa 4, Amp igipimo kuva 25 A kugeza 100 A, kugendagenda kumurongo B, Ubwoko A cyangwa AC hamwe na mA kuva 30 kugeza 100 mA.
Byaba byiza, byaba byiza ukoresheje ubu bwoko bwa breaker kugirango wirinde impanuka zatewe nimpanuka.Umuyoboro wose unyura kumuntu ufite agaciro karenze 30 mA urashobora gutwara umutima muri fibrillation ya ventricular ventricular (cyangwa guta injyana yumutima) - niyo mpamvu nyamukuru itera urupfu binyuze mumashanyarazi.RCD ihagarika umuyaga muri milisegonda 25 kugeza kuri 40 mbere yuko amashanyarazi ashobora kubaho.Ibinyuranyo, imiyoboro isanzwe yumuzunguruko nka MCB / MCCB (Miniature Circuit Breaker) cyangwa fuse iracika gusa mugihe umuyoboro wumuzunguruko urenze urugero (ushobora kuba inshuro ibihumbi nibihumbi byumuyaga RCD isubiza).Akantu gato kameneka kanyuze mumubiri wumuntu karashobora kuba bihagije kukwica.Nubwo bimeze bityo, birashoboka ko bitazongera imbaraga zose zihagije kuri fuse cyangwa kurenza imitwaro yamashanyarazi kandi ntabwo yihuta kugirango urokore ubuzima bwawe.
Itandukaniro nyamukuru hagati yibi byuma byumuzunguruko ni uko RCBO ifite ibikoresho byerekana ibintu byinshi.Kuri iyi ngingo, ushobora kuba utekereza impamvu bagurisha ibicuruzwa bitandukanye niba bigaragara ko hari itandukaniro rimwe gusa hagati yabo?Ubona gute ugurishije ubwoko gusa mwisoko?Niba uhisemo gukoresha RCBO cyangwa RCD biterwa n'ubwoko bwo kwishyiriraho na bije.Kurugero, mugihe hari isi yamenetse mumasanduku yo gukwirakwiza ukoresheje ibyuma byose bya RCBO, gusa kumena hamwe na switch idahwitse bizashira.Nyamara, ubu bwoko bwiboneza ibiciro burenze gukoresha RCD.Niba bije ari ikibazo, urashobora gushiraho MCB eshatu kuri enye munsi yigikoresho gisigaye.Urashobora kandi kuyikoresha mubikorwa bidasanzwe nka jacuzzi cyangwa kwishyiriraho igituba gishyushye.Kwiyubaka bisaba kwihuta kandi bitagikora, muri rusange 10mA.Kurangiza, uwamena ushaka gukoresha biterwa nigishushanyo mbonera cya bije yawe.Ariko, niba ugiye gushushanya cyangwa kuzamura switch yawe kugirango ugume mumabwiriza kandi urebe neza uburyo bwiza bwo kurinda amashanyarazi kumitungo yibikoresho ndetse nubuzima bwabantu, menya neza kuvugana numuhanga wizewe wamashanyarazi.
AFDD nigikoresho cya Arc Ikosa Kumenyekanisha kandi cyashizweho kugirango hamenyekane ahari amashanyarazi y’amashanyarazi ateye akaga no guhagarika uruziga rwagize ingaruka.Ibikoresho bya Arc Kumenyekanisha bikora ukoresheje tekinoroji ya microprocessor kugirango isesengure imiterere yumuriro wamashanyarazi.Babona umukono udasanzwe wasobanura arc kumuzunguruko.AFDD izahita ihagarika ingufu kumuzunguruko wibasiwe no gukumira umuriro.Birumvikana cyane kuri arc kuruta ibikoresho bisanzwe byo kurinda imiyoboro nka MCBs & RBCOs.
