I-AFCI i-circuit breaker ethuthukisiwe ezophula isekethe lapho ithola i-arc kagesi eyingozi kusekethe eyivikelayo.
I-AFCI ingahlukanisa ngokukhetha uma kuyi-arc engenangozi ehambisana nokusebenza okuvamile kwamaswishi namapulaki noma i-arc eyingozi engenzeka, njengentambo yesibani enekhondatha ephukile.I-AFCI yakhelwe ukuthola inqwaba yamaphutha kagesi afaka ama-arcing asiza ukunciphisa isistimu kagesi ekubeni umthombo womlilo.
Nakuba i-AFCIs yethulwa futhi yabhalwa kumakhodi kagesi ngasekupheleni kwawo-1990 (izoxoxa ngemininingwane kamuva), izinganekwane eziningana zisazungeza ama-AFCIs - izinganekwane ezivame ukukholelwa ngabanikazi bezindlu, izishayamthetho zombuso, amakhomishana okwakha, ngisho nabanye abasebenza ngogesi.
Inganekwane 1:Ama-AFCI awekhoso okubalulekile uma kuziwa ekusindiseni izimpilo
"Ama-AFCI angamathuluzi okuphepha abaluleke kakhulu afakazelwe izikhathi eziningi," kusho u-Ashley Bryant, umphathi omkhulu wemikhiqizo ye-Siemens.
Amaphutha e-arc angenye yezimbangela eziphambili zemililo kagesi yokuhlala.Ngeminyaka yawo-1990, ngokusho kweKhomishini Yokuphepha Komkhiqizo Wabathengi base-US (i-CPSC), isilinganiso semililo engaphezu kuka-40,000 ngonyaka kuthiwa ibangelwa izintambo zikagesi zasendlini, okubangele ukufa kwabantu abangaphezu kuka-350 kanye nokulimala kuka-1,400.I-CPSC iphinde yabika ukuthi ngaphezu kwamaphesenti angama-50 ale mililo ibingavinjelwa uma kusetshenziswa ama-AFCI.
Ngaphezu kwalokho, i-CPSC ibika ukuthi imililo kagesi ngenxa ye-arcing ngokuvamile ivela ngemuva kwezindonga, okuyenza ibe yingozi kakhulu.Okusho ukuthi, le mililo ingabhebhetheka ingabonakali ngokushesha, ngakho-ke ingabangela umonakalo omkhulu kuneminye imililo, futhi igcina isibulala ngokuphindwe kabili kunemililo engenzeki ngemva kwezindonga, njengoba abanikazi bezindlu bevame ukungayiqapheli imililo engemuva kwezindonga kuze kube yilapho kungenzeka. sephuze kakhulu ukubaleka.
Inganekwane 2:Abakhiqizi be-AFCI bashayela izimfuneko zekhodi ezinwetshiwe zokufakwa kwe-AFCI
"Ngithola le nganekwane ivamile lapho ngikhuluma nabashayamthetho, kodwa imboni kagesi kufanele iqonde iqiniso futhi lapho bekhuluma nezigele zabo zombuso kanye namakhomishana okwakha," kusho u-Alan Manche, iphini likamongameli, izindaba zangaphandle, zeSchneider Electric. .
Empeleni idrayivu yezidingo zekhodi ekhulayo ivela ocwaningweni lwezinkampani zangaphandle.
I-Consumer Product Safety Commission kanye nocwaningo olwenziwe yi-UL mayelana nezinkulungwane zemililo eyenzeka ezindlini ngasekupheleni kwawo-1980 nasekuqaleni kwawo-1990 kwashayela ukuze kutholwe izimbangela zale mililo.Ukuvikelwa kwamaphutha kwe-Arc sekube yisixazululo esabonwa yi-CPSC, UL, nabanye.
Inganekwane 3:Ama-AFCI adingeka kuphela ngamakhodi enanini elincane lamagumbi ezindlini zokuhlala
"I-National Electrical Code ibilokhu ikhulisa ukufinyelela kwama-AFCI ngaphandle kwezindlu zokuhlala," kusho uJim Phillips, umongameli we-PE we-Brainfiller.com.
Imfuneko yokuqala Kazwelonke Yekhodi Kagesi (NEC) yama-AFCIs eyakhishwa ngo-1999 yayidinga ukuthi afakwe ukuze kuvikelwe amasekhethi aphakela amakamelo okulala ezindlini ezintsha.Ngo-2008 no-2014, i-NEC yanwetshwa ukuze idinge ukuthi ama-AFCI afakwe kumasekhethi emagumbini amaningi kakhulu ezindlini, manje esehlanganisa cishe wonke amagumbi—amakamelo okulala, amagumbi omndeni, amagumbi okudlela, amagumbi okuhlala, amagumbi elanga, amakhishi, imihume, amahhovisi asekhaya. , amaphasishi, amagumbi okungcebeleka, amagumbi okuwasha ngisho nezingubo zokugqoka.
Ukwengeza, i-NEC iphinde yaqala ukudinga ukusetshenziswa kwama-AFCI ezindlini zokulala zasekolishi kusukela ngonyaka wezi-2014. Iphinde yandisa izidingo ukuze zibandakanye amagumbi amahhotela/amamotela ahlinzeka ngemibandela yokupheka unomphela.
Inganekwane 4:I-AFCI ivikela kuphela lokho okuxhunywe endaweni ethile enesici ecupha i-arc kagesi.
"I-AFCI empeleni ivikela yonke isekethe esikhundleni sokuvikela kuphelai-outlet ethize enesici ebangela i-arc kagesi,” kusho u-Rich Korthauer, iphini likamongameli, ibhizinisi lokugcina lokusabalalisa, le-Schneider Electric.“Faka izintambo zikagesi, izintambo zikagesi eziya ezansi nomfula ezihamba odongeni, izindawo zokuphuma, amaswishi, zonke izixhumo zalezo zintambo, izindawo zokuphuma kanye namaswishi, nanoma yini exhunywe kunoma iyiphi yalezo zindawo futhi exhunywe kumaswishi kuleyo sekethi. .”
Inganekwane 5:I-circuit breaker ejwayelekile izohlinzeka ngokuvikeleka okuningi njenge-AFCI
Abantu babecabanga ukuthi i-breaker ejwayelekile izohlinzeka ngokuvikeleka okuningi njenge-AFCI, kodwa empeleni ama-circuit breaker aphendula kuphela ekulayisheni ngokweqile namasekhethi amafushane.Azivikeli ngokumelene nezimo ze-arcing ezikhiqiza ukuguquguquka nokuvame ukunciphisa okwamanje.
I-circuit breaker ejwayelekile ivikela ukufakwa ocingweni ekulayisheni ngokweqile, akuhloselwe ukukhomba ama-arcs amabi kumasekhethi ekhaya.Yiqiniso, i-circuit breaker evamile iklanyelwe ukukhubeka futhi iphazamise leso simo uma une-short short.
Inganekwane 6:Iningi “lohambo” lwe-AFCIkwenzeka ngobakukhona "ukukhubeka kwenkathazo"
U-Siemens' uBryant uthe uzwe le nganekwane kakhulu.“Abantu bacabanga ukuthi ama-arc fault breaker athile anesici ngoba avame ukukhubeka.Abantu badinga ukucabanga ngalokhu njengezaziso zokuphepha kunokukhubeka kwenkathazo.Izikhathi eziningi, lawa mahlephuli ahamba ngoba kufanele.Bayakhubeka ngenxa yomcimbi othize we-arcing on the circuit.”
Lokhu kungaba yiqiniso ngezimpahla "zokugwaza", lapho izintambo zilayishwa entwasahlobo ngemuva kwezimpahla ezingafaki izintambo ezizungeze izikulufu, ezihlinzeka ngoxhumo oluqinile.Ezimweni eziningi, lapho abanikazi bezindlu bexhuma ama-plugs ezitsheni ezilayishwe entwasahlobo noma bazikhiphe cishe, imvamisa ixhumanisa izinto ezifakwayo, ivumela izintambo ukuba zixege, okuzokwenza ukuthi ama-arc fault breaker ahambe.
