I-AFCI yi-breaker circuit ehamba phambili eya kuphula isiphaluka xa ibona i-arc yombane eyingozi kwisiphaluka esiyikhuselayo.
I-AFCI inokukhetha ngokukhethayo ukuba i-arc engenabungozi eyenzeka ekusebenzeni okuqhelekileyo kokutshintsha kunye neeplagi okanye i-arc enokuba yingozi enokuthi yenzeke, njengentambo yesibane ene-conductor eyaphukileyo.I-AFCI yenzelwe ukukhangela uluhlu olubanzi lweempazamo zombane ezinceda ukunciphisa inkqubo yombane ekubeni ngumthombo wokutshisa umlilo.
Nangona i-AFCIs yaziswa kwaye yabhalwa kwiikhowudi zombane ekupheleni kweminyaka yee-1990 (ziya kuxubusha iinkcukacha ngakumbi kamva), iintsomi ezininzi zisajikeleza i-AFCIs-iintsomi zihlala zikholelwa ngabanini bezindlu, abawi-mthetho belizwe, iikhomishini zokwakha, kunye nabanye oombane.
INGQONGO 1:Ii-AFCI azikhoso kubalulekile xa kuziwa ekusindiseni ubomi
"I-AFCI zizixhobo zokhuseleko ezibaluleke kakhulu eziye zabonakaliswa ngamaxesha amaninzi," kusho u-Ashley Bryant, umphathi omkhulu wemveliso ye-Siemens.
Iimpazamo ze-arc ngomnye woonobangela abaphambili bemililo yombane kwindawo yokuhlala.Ukutyhubela iminyaka yoo-1990, ngokweKhomishini yoKhuseleko lweMveliso yoMthengi yase-US (CPSC), umyinge wemililo engaphezulu kwama-40,000 ngonyaka ibalelwa kwiintambo zombane zasekhaya, ezikhokelela ekufeni kwabantu abangaphezu kwama-350 kunye nokwenzakala okungaphezulu kwe-1,400.I-CPSC iphinde yaxela ukuba ngaphezulu kwe-50 yepesenti yale mililo ibinokuthintelwa xa kusetyenziswa ii-AFCIs.
Ukongeza, i-CPSC ibika ukuba imililo yombane ngenxa ye-arcing idla ngokuvela emva kweendonga, ibenze ibe yingozi ngakumbi.Oko kukuthi, le mililo inokunwenwa ngokukhawuleza ingabonakali ngokukhawuleza, ngoko ke inokubangela umonakalo omkhulu kuneminye imililo, yaye ekugqibeleni ibulala ngokuphindwe kabini kunomlilo ongenzekiyo emva kweendonga, ekubeni abaninimzi bethanda ukungayiqondi imililo esemva kweendonga de ifike. kuba kakhulu ukubaleka.
IINGQONDO 2:Abavelisi be-AFCI baqhuba iimfuno zekhowudi ezandisiweyo zokufakelwa kwe-AFCI
"Ndiyifumana le ntsomi ixhaphake xa ndithetha nabasemthethweni, kodwa imboni yombane kufuneka iqonde inyani xa bethetha kunye neesenenja zabo zelizwe kunye neekomishini zokwakha," kusho u-Alan Manche, usekela-mongameli, imicimbi yangaphandle, yeSchneider Electric. .
Ngokwenyani idrayivu yeemfuno zekhowudi ezandiswayo zivela kuphando lomntu wesithathu.
IKomishoni yoKhuseleko lweMveliso yoMthengi kunye nezifundo eziqhutywe yi-UL ngokubhekiselele kumawaka emililo eyenzeka kumakhaya ekupheleni kwe-1980s kunye ne-1990 yokuqala yaqhuba ukufumanisa izizathu zale mililo.Ukukhuselwa kwempazamo ye-Arc kuye kwaba sisisombululo esaqatshelwa yi-CPSC, UL, kunye nabanye.
IINGQONDO 3:Ii-AFCI zifunwa kuphela ngeekhowudi kwinani elincinci lamagumbi kumakhaya okuhlala
"IKhowudi yoMbane yeSizwe iye yandisa ukufikelela kwe-AFCI ngaphaya kwezindlu zokuhlala," kusho uJim Phillips, umongameli we-PE we-Brainfiller.com.
Imfuno yokuqala yeSizwe yoMbane yeKhowudi (NEC) yeemfuno ze-AFCIs ezakhutshwa ngo-1999 zafuna ukuba zifakelwe ukukhusela iisekethe zokutyisa amagumbi okulala kumakhaya amatsha.Kwi-2008 kunye ne-2014, i-NEC yandiswa ukuze ifune ukuba i-AFCIs ifakwe kwiisekethe ukuya kumagumbi angaphezulu nangaphezulu kumakhaya, ngoku igubungela phantse onke amagumbi-amagumbi okulala, amagumbi osapho, amagumbi okudlela, amagumbi okuhlala, amagumbi elanga, iikhikhithi, iindawo zokuhlala, iiofisi zasekhaya. , iipaseji, amagumbi okuzihlaziya, amagumbi okuhlambela iimpahla, kwanamagumbi okuhlamba.
Ukongeza, i-NEC nayo yaqalisa ukufuna ukusetyenziswa kwee-AFCIs kumagumbi okulala ekholeji ukususela ngonyaka ka-2014. Kwakhona iye yazandisa iimfuno ukuze ibandakanye amagumbi ehotele/emotele abonelela ngamalungiselelo asisigxina okupheka.
INKOMO 4:I-AFCI ikhusela kuphela into eplagwe kwindawo ethile eneziphene eyenza i-arc yombane.
“I-AFCI eneneni ikhusela yonke isekethe endaweni yokuphela kwayoindawo ethile enesiphene ebangela i-arc yombane, "watsho u-Rich Korthauer, usekela-mongameli, ishishini lokugqibela lokusasaza, kwi-Schneider Electric."Bandakanya ipaneli yombane, iingcingo ezisezantsi ezityhutyha iindonga, iindawo zokuphuma, izitshixo, zonke iintambo zombane, iindawo zokuphuma kunye nezitshixo, nayo nayiphi na into eqhagamshelwe kuyo nayiphi na kwezo zixhobo kwaye iqhagamshelwe kwizitshixo kuloo sekethi. .”
IINGQONDO 5:Umqhekezi wesekethe oqhelekileyo uya kubonelela ngokhuseleko oluninzi njenge-AFCI
Abantu bacinga ukuba i-breaker standard iya kubonelela ngokhuseleko oluninzi njenge-AFCI, kodwa eneneni abaphuli beesekethe eziqhelekileyo baphendula kuphela kumthwalo ogqithisiweyo kunye neesekethe ezimfutshane.Abakhuseli kwiimeko ze-arcing ezivelisa ngokungaqhelekanga kwaye zihlala zinciphisa okwangoku.
I-breaker circuit breaker ikhusela i-insulation kwi-wire kwi-overload, ayijoliswanga ukuchonga ii-arcs ezimbi kwiisekethe ekhaya.Ewe kunjalo, i-breaker circuit yenzelwe ukukhubeka kwaye iphazamise loo meko ukuba ufile.
IINGQONDO 6:Uninzi "lohambo" lwe-AFCIkwenzeka ngenxa yokuba"zihamba ngokukhawuleza"
U-Siemens uBryant uthe wayiva le ntsomi kakhulu.“Abantu bacinga ukuba ezinye ii-arc fault breakers zineziphene kuba zihlala zikhubeka.Abantu kufuneka bacinge ngezi zinto njengezilumkiso zokhuseleko kunokukhubeka.Uninzi lwexesha, aba baqhekezi bahamba kuba bekufanele ukuba.Bayakhubeka ngenxa yohlobo oluthile lomnyhadala we-arcing kwisekethe. ”
Oku kunokuba yinyani kunye nezixhobo "zokugwaza", apho iingcingo zilayishwa entwasahlobo emva kwezixhobo ezingenacingo ezijikeleze izikrufu, ezibonelela ngokudityaniswa okuqinileyo.Kwiimeko ezininzi, xa abaninimzi befakela i-jam kwizixhobo ezilayishwe entwasahlobo okanye bazikhuphe ngokukhawuleza, zihlala zixubha izixhobo, zivumela iingcingo ukuba zikhululeke, eziya kubangela ukuba i-arc fault breakers ihambe.
