AFCI ndeye advanced circuit breaker iyo inotyora dunhu kana yaona ine njodzi yemagetsi arc mudunhu rainodzivirira.
AFCI inokwanisa kusarudza kusiyanisa kana iri arc isingakuvadzi inongoitika kune yakajairika mashandiro ekuchinja nemapulagi kana arc ine njodzi inogona kuitika, senge tambo yemwenje ine conductor yakatyoka.Iyo AFCI yakagadzirirwa kuona kuwanda kwekukanganisa kwemagetsi kunobatsira kuderedza hurongwa hwemagetsi kubva pakuva bviro yemoto.
Kunyange zvazvo AFCIs yakaunzwa uye yakanyorwa mumakodhi emagetsi mukupera kwema1990 (ichakurukura zvakadzama gare gare), nhema dzakawanda dzichiri kupoteredza AFCIs-ngano dzinowanzotendwa nevaridzi vedzimba, vezvematongerwo enyika, zvivako zvekuvaka, uye kunyange vamwe vemagetsi.
NGANO 1:AFCIs haasiso zvakakosha kana zvasvika pakuponesa hupenyu
"AFCIs zvakakosha midziyo yekuchengetedza yakaratidzwa kakawanda," akadaro Ashley Bryant, mukuru wechigadzirwa maneja weSiemens.
Arc kukanganisa ndeimwe yezvikonzero zvinokonzeresa moto wemagetsi ekugara.Kuburikidza nema1990s, maererano neUS Consumer Product Safety Commission (CPSC), avhareji yemoto inopfuura zviuru makumi mana pagore yainzi yakakonzerwa newaya dzemagetsi epamba, zvichikonzera kufa kwevanhu vanopfuura mazana matatu nemakumi mashanu uye vanopfuura zviuru zana nemakumi mana vakakuvadzwa.CPSC yakataurawo kuti pamusoro pe50 muzana yemoto uyu waigona kudzivirirwa paishandiswa AFCIs.
Uye zvakare, iyo CPSC inoshuma kuti moto wemagetsi nekuda kwearcing unowanzoitika kuseri kwemadziro, zvichiita kuti zvive nengozi.Kureva kuti, moto uyu unogona kupararira usingaonekwi nekukurumidza, saka unogona kukonzera kukuvadza kwakawanda kupfuura mimwe moto, uye unoguma wauraya zvakapetwa kaviri semoto usingabvi kuseri kwemadziro, sezvo varidzi vedzimba vasingawanzoziva nezvemoto uri seri kwemadziro kusvikira wagona. kunonoka kutiza.
NGANO 2:Vagadziri veAFCI vari kutyaira yakawedzera kodhi zvinodiwa pakuiswa kweAFCI
"Ini ndinoona ngano iyi yakajairika pandinenge ndichitaura nevamiriri vemitemo, asi indasitiri yemagetsi inofanirwa kunzwisisa chokwadi pavanenge vachitaura nemaseneta ehurumende uye makomisheni ekuvaka," akadaro Alan Manche, mutevedzeri wemutungamiri, wezvekunze, weSchneider Electric. .
Chaizvoizvo dhiraivha yekuwedzera kodhi zvinodiwa iri kuuya kubva kune wechitatu-bato tsvagiridzo.
Consumer Product Safety Commission uye zvidzidzo zvakaitwa neUL maererano nezviuru zvemoto unoitika mudzimba mukupera kwema1980 uye kutanga kwa1990s vakatyaira kuti vaone zvikonzero zvemoto uyu.Kudzivirirwa kweArc kukanganisa kwave mhinduro yakazivikanwa neCPSC, UL, nevamwe.
NGANO 3:AFCIs inongodiwa chete nemakodhi munhamba shoma yemakamuri mudzimba dzekugara
"National Electrical Code yanga ichiwedzera kusvika kweAFCIs kupfuura dzimba dzekugara," akadaro Jim Phillips, mutungamiri wePE weBrainfiller.com.
Yekutanga National Electrical Code (NEC) inodiwa yeAFCIs yakabudiswa muna 1999 yaida kuti iiswe kuchengetedza matunhu ekudyisa makamuri mudzimba nyowani.Muna 2008 na 2014, NEC yakawedzerwa kuti iite kuti ma AFCI aiswe pamaseketi kumakamuri akawanda uye akawanda mudzimba, zvino achivhara anenge makamuri ese — dzimba dzekurara, dzimba dzemhuri, dzimba dzekudyira, dzimba dzekutandarira, dzimba dzezuva, kicheni, madhimba, mahofisi epamba. , mikoto, dzimba dzokutandarira, dzimba dzokuwachira, uye kunyange mawadhiropu.
Pamusoro pezvo, NEC yakatangawo kuda kuti maAFCI ashandiswe mudzimba dzokurara dzepakoreji kubva mugore ra2014. Yakawedzerawo zvinodiwa kuti zvibatanidze makamuri ehotera/motel anopa zvinhu zvechigarire zvekubika.
NGANO 4:Iyo AFCI inongodzivirira iyo yakavharirwa mune chaiyo yakaremara kubuda iyo inokonzeresa arc yemagetsi.
"AFCI inochengetedza dunhu rose panzvimbo peiyo chetechakananga chakaremara chinoburitsa chinokonzeresa arc yemagetsi, "akadaro Rich Korthauer, mutevedzeri wemutungamiri, bhizinesi rekupedzisira rekugovera, reSchneider Electric.“Batanidza tambo dzemagetsi, tambo dzepasi dzinopfuura nemumadziro, maburi, maswichi, zvese zvinosungirirwa waya, maburi nema switch, uye chero chinhu chinobairwa mune chero chekubuda ikoko uye chakabatana nema switch pasaiti iyoyo. .”
NGANO 5:Iyo yakajairwa wedunhu breaker ichapa kuchengetedzwa kwakawanda senge AFCI
Vanhu vaifunga kuti iyo yakajairwa breaker yaizopa dziviriro yakawandisa seAFCI, asi chaizvo akajairwa edunhu mabreak anongopindura kune zvakawandisa uye mapfupi maseketi.Ivo havadziviriri kubva kune arcing mamiriro anoburitsa zvisizvo uye anowanzo kuderedzwa ikozvino.
A standard circuit breaker inodzivirira kuvharirwa pawaya kubva pakuremerwa, haina kurongerwa kuona yakaipa arcs pamasekete mumba.Ehe, yakajairwa yedunhu breaker yakagadzirirwa kutsika uye kukanganisa iyo mamiriro kana uine yakafa ipfupi.
NYAYA 6:Mazhinji AFCI "nzendo"zvinoitika nekuti ivovari "kunetsekana kukwira"
Siemens 'Bryant akati akanzwa ngano iyi zvakanyanya.“Vanhu vanofunga kuti mamwe maarc fault breaker haana kukwana nekuti anogara achifamba.Vanhu vanofanirwa kufunga nezvazvo seyambiro dzekuchengetedza kwete kugumburwa.Nguva zhinji, mabreaker aya anofamba nekuti anofanirwa kudaro.Vari kugumburwa nekuda kweimwe mhando yechiitiko che arcing padunhu. ”
Izvi zvinogona kuve zvechokwadi ne "kubaya" zvigadziko, uko waya dzinotakurwa-kuiswa kumashure kwemidziyo isina waya yakatenderedza screws, iyo inopa hukama hwakasimba.Muzviitiko zvakawanda, kana varidzi vemba vachiisa plugs muzvigadziro zvakatakurwa-muchirimo kana kuaburitsa kunze, kazhinji inomhanyisa midziyo, ichibvumira waya kuti dzisununguke, izvo zvinozoita kuti arc fault breaker ifambe.
