Sobanukirwa Amakosa ya Arc no Kurinda AFCI

Ijambo "arc amakosa" bivuga ikibazo cyoguhuza insinga zangiritse cyangwa zangiritse zitera guhuza rimwe na rimwe kugirango bitume umuyagankuba ucana cyangwa arc hagati yicyuma.Urimo wumva arcing iyo wunvise urumuri rworoheje cyangwa isohoka ryumvikana cyangwa urusaku.Iyi arcing isobanura ubushyuhe hanyuma igatanga imbarutso yumuriro wamashanyarazi, ibi mubyukuri bisenya insulation ikikije insinga ziyobora.Kumva switch buzz ntabwo bivuze ko byanze bikunze umuriro uri hafi, ariko bivuze ko hari akaga gashobora gukemurwa.

Ikosa rya Arc vs Ikosa ryubutaka nizunguruka rigufi

Amagambo arc amakosa, ikosa ryubutaka, hamwe nigihe gito-cyizunguruka rimwe na rimwe byateje urujijo, ariko mubyukuri bifite ibisobanuro bitandukanye, kandi buri kimwe gisaba ingamba zitandukanye zo gukumira.

• Ikosa rya arc, nkuko byavuzwe haruguru, ribaho mugihe insinga zidafunitse cyangwa insinga zangiritse zitera gucana cyangwa guterana, bishobora gutera ubushyuhe nubushobozi bwumuriro wamashanyarazi.Birashobora kuba intangiriro yumuzunguruko mugufi cyangwa ikosa ryubutaka, ariko kandi ubwabyo, ikosa rya arc ntirishobora guhagarika haba GFCI cyangwa icyuma cyangiza.Uburyo busanzwe bwo kwirinda amakosa ya arc ni AFCI (arc-fault circuit interrupter) - haba hanze ya AFCI cyangwa kumena amashanyarazi ya AFCI.AFCIs igamije gukumira (kwirinda) akaga k'umuriro.
• Ikosa ryubutaka risobanura ubwoko bwumuzunguruko mugufi aho imbaraga "zishyushye" zituma habaho impanuka kubutaka.Rimwe na rimwe, ikosa ryubutaka rizwi nk '“igihe gito-ku butaka.”Kimwe nubundi bwoko bwumuzunguruko mugufi, insinga zumuzingi zitakaza imbaraga mugihe cyikosa ryubutaka, kandi ibyo bitera urujya n'uruza rwumuvuduko rugomba gutuma icyuma cyizunguruka kigenda.Nyamara, icyuma cyumuzunguruko ntigishobora gukora byihuse kugirango wirinde guhungabana, Kode yamashanyarazi isaba ibikoresho byihariye byo gukingira kubwiyi mpamvu, niyo mpamvu GFCIs (interineti ikemura ibibazo byubutaka) igomba gushyirwaho ahantu hashobora kugaragara amakosa yubutaka, nk'ahantu hasohokera imiyoboro y'amazi cyangwa ahantu hanze.Barashobora guhagarika umuzunguruko na mbere yuko habaho guhungabana kuko ibyo bikoresho byumva imbaraga zihinduka vuba cyane.GFCIs rero, nigikoresho cyumutekano kigenewe ahanini kwirindaguhungabana.
• Umuzunguruko mugufi bivuga ibihe byose bitera imbaraga "zishyushye" zigenda hanze ya sisitemu yashizweho kandi igahuza inzira yaba itabogamye cyangwa inzira yo guhagarara.Urujya n'uruza rw'amashanyarazi rutakaza imbaraga zayo kandi rwiyongera mubunini mugihe ibi bibaye.Ibi byihuse bitera umuvuduko urenze ubushobozi bwa amperage yamashanyarazi yamashanyarazi agenzura uruziga, mubisanzwe bigenda kugirango uhagarike umuvuduko.

Kode Amateka yo Kurinda Amakosa

NEC (Code of National Electrical Code) ivugurura inshuro imwe mumyaka itatu, yagiye yongera buhoro buhoro ibisabwa kugirango irinde amakosa-arc kumuzunguruko.

Kurinda Arc-Ikosa Niki?

Ijambo "arc-amakosa yo gukingira" ryerekeza ku gikoresho icyo ari cyo cyose cyagenewe kurinda imiyoboro idahwitse itera arcing, cyangwa ikayangana.Igikoresho cyo gutahura cyumva arc amashanyarazi kandi kigahagarika uruziga kugirango birinde umuriro w'amashanyarazi.Ibikoresho birinda Arc-amakosa birinda abantu ibyago kandi nibyingenzi mumutekano wumuriro.

Mu 1999, Code yatangiye gusaba kurinda AFCI mumuzunguruko wose ugaburira ibyumba byo kuraramo, kandi guhera mumwaka wa 2014 ,, imirongo hafi ya yose itanga amasoko rusange ahantu hatuwe birasabwa kugira uburinzi bwa AFCI mubwubatsi bushya cyangwa mumishinga yo kuvugurura.

Kugeza muri NEC yo muri 2017, amagambo yo mu gice cya 210.12 agira ati:

Byose120-volt, icyiciro kimwe, 15- na 20-ampere yumuzunguruko utanga ibicuruzwa cyangwa ibikoresho byashyizwe mubikoni byamazu, ibyumba byumuryango, ibyumba byo kuriramo, ibyumba byo kubamo, salle, amasomero, indiri, ibyumba byo kuryamo, ibyumba byizuba, ibyumba byo kwidagadura, akabati, koridoro, aho bamesera, cyangwa ibyumba bisa cyangwa uturere bizarindwa na AFCIs.

Mubisanzwe, imizunguruko yakira uburinzi bwa AFCI hifashishijwe ibyuma bidasanzwe byumuzunguruko wa AFCI birinda ahantu hose nibikoresho byose kumuzunguruko, ariko aho ibi bidafatika, urashobora gukoresha ibicuruzwa bya AFCI nkibisubizo byububiko.

Kurinda AFCI ntabwo ari nkenerwa mubikorwa bisanzwe, ariko aho umuzunguruko waguwe cyangwa ukavugururwa mugihe cyo kuvugurura, ugomba noneho kwakira uburinzi bwa AFCI.Rero, umuyagankuba ukora kuri sisitemu asabwa kuvugurura umuzenguruko hamwe nuburinzi bwa AFCI nkigice cyakazi cyose abikoraho.Mu buryo bufatika, bivuze ko abasimbuye inzitizi zose zumuzunguruko noneho zizakorwa hamwe na AFCI kumena mububasha ubwo aribwo bwose bwo gukurikiza NEC (Code of National Electrical Code).

Ntabwo abaturage bose bubahiriza NEC, ariko, nyamuneka nyamuneka reba ubuyobozi bwibanze kubisabwa bijyanye no kurinda AFCI.
