Onetsani Nthano zisanu ndi imodzi za AFCI

AFCI ndi chowotcha chapamwamba chomwe chimathyola dera likazindikira arc yowopsa yamagetsi yomwe imateteza.

AFCI imatha kusiyanitsa mwachisawawa ngati ndi arc yopanda vuto yomwe imachitika mwachizolowezi cha masiwichi ndi mapulagi kapena ma arc owopsa omwe angachitike, monga chingwe cha nyali chokhala ndi kondakita wosweka.AFCI idapangidwa kuti izindikire zovuta zambiri zamagetsi zomwe zimathandiza kuchepetsa mphamvu yamagetsi kuti ikhale gwero lamoto.

Ngakhale kuti ma AFCI adayambitsidwa ndikulembedwa m'makhodi amagetsi kumapeto kwa zaka za m'ma 1990 (tidzakambirana zambiri pambuyo pake), nthano zambiri zimazungulira ma AFCI - nthano zomwe nthawi zambiri zimakhulupilira ndi eni nyumba, aphungu a boma, makomiti omanga nyumba, komanso ngakhale ena amagetsi.

MFUNDO 1:Ma AFCI palibeso zofunika pankhani yopulumutsa miyoyo

"AFCIs ndi zida zofunika kwambiri zotetezera zomwe zatsimikiziridwa nthawi zambiri," adatero Ashley Bryant, mkulu wa mankhwala a Siemens.

Kuwonongeka kwa Arc ndi chimodzi mwazomwe zimayambitsa moto wamagetsi m'nyumba.Kupyolera m'ma 1990, malinga ndi US Consumer Product Safety Commission (CPSC), pafupifupi moto wopitilira 40,000 pachaka umachitika chifukwa cha waya wamagetsi apanyumba, zomwe zidapha anthu opitilira 350 ndikuvulala kopitilira 1,400.CPSC idanenanso kuti kupitilira 50 peresenti yamotowu ukadatha kupewedwa mukamagwiritsa ntchito ma AFCI.

Kuphatikiza apo, CPSC imanena kuti moto wamagetsi chifukwa cha kutsekeka nthawi zambiri umachitika kuseri kwa makoma, kuwapangitsa kukhala owopsa.Ndiko kuti, moto umenewu ukhoza kufalikira popanda kuzindikirika mofulumira kwambiri, choncho ukhoza kuwononga kwambiri kuposa moto wina, ndipo pamapeto pake umakhala wakupha kuwirikiza kawiri kuposa moto umene sunachitike kuseri kwa makoma, popeza eni nyumba amakonda sadziwa za moto umene uli kuseri kwa makomawo mpaka utatha. kuchedwa kwambiri kuthawa.

MFUNDO 2:Opanga AFCI akuyendetsa zofunikira zowonjezera ma code kuti akhazikitse AFCI

"Ndimaona kuti nthano imeneyi imakhala yofala ndikamalankhula ndi aphungu, koma makampani opanga magetsi akuyenera kumvetsetsa zenizeni pamene akuyankhula ndi aphungu awo a boma ndi zomangamanga," adatero Alan Manche, wachiwiri kwa pulezidenti, zochitika zakunja, kwa Schneider Electric. .

Kwenikweni chiwongolero chofuna kukulitsa ma code chikuchokera ku kafukufuku wachipani chachitatu.

Bungwe la Consumer Product Safety Commission ndi kafukufuku wopangidwa ndi UL wokhudzana ndi zikwi za moto zomwe zimachitika m'nyumba kumapeto kwa zaka za m'ma 1980 ndi kumayambiriro kwa zaka za m'ma 1990 adayendetsa galimoto kuti adziwe zomwe zimayambitsa motowu.Chitetezo cha zolakwika za Arc chakhala yankho lomwe linadziwika ndi CPSC, UL, ndi ena.

MFUNDO 3:Ma AFCI amangofunika ndi ma code m'zipinda zochepa za nyumba zogona

"National Electrical Code yakhala ikukulitsa kufikira kwa AFCI kupitilira nyumba zogona," adatero Jim Phillips, Purezidenti wa PE wa Brainfiller.com.

Chofunikira choyamba cha National Electrical Code (NEC) cha AFCI chomwe chinatulutsidwa mu 1999 chinafuna kuti akhazikitsidwe kuti ateteze mabwalo odyetsa zipinda m'nyumba zatsopano.Mu 2008 ndi 2014, NEC idakulitsidwa kuti ifune kuti ma AFCI akhazikitsidwe m'mabwalo kupita ku zipinda zochulukirapo m'nyumba, zomwe zikuphatikiza pafupifupi zipinda zonse - zipinda zogona, zipinda za mabanja, zipinda zodyera, zipinda zochezera, zipinda za dzuwa, khitchini, mapanga, maofesi apanyumba. , makoleji, zipinda zachisangalalo, zipinda zochapira zovala, ndipo ngakhale zofunda.

Kuphatikiza apo, NEC idayambanso kufuna kugwiritsa ntchito ma AFCI m'nyumba zogona zapakoleji kuyambira chaka cha 2014. Yakulitsanso zofunikira kuti ziphatikize zipinda za hotelo/motelo zomwe zimapereka chakudya chokhazikika chophikira.

MFUNDO 4:AFCI imangoteteza zomwe zalumikizidwa munjira inayake yolakwika yomwe imayambitsa arc yamagetsi.

"AFCI imateteza dera lonse m'malo mongotetezakutulutsa kolakwika komwe kumayambitsa arc yamagetsi, "anatero a Rich Korthauer, wachiwiri kwa pulezidenti, bizinesi yomaliza yogawa, kwa Schneider Electric."Phatikizani magetsi, mawaya akumunsi omwe amadutsa m'makoma, zotulutsira, zosinthira, zolumikizira zonse ku mawayawo, mawaya ndi masiwichi, ndi chilichonse chomwe chimalumikizidwa munjira iliyonse ndikulumikizidwa ndi ma switch pagawolo. .”

MFUNDO 5:Wowononga dera wokhazikika adzapereka chitetezo chofanana ndi AFCI

Anthu ankaganiza kuti wophwanya wamba angapereke chitetezo chochuluka ngati AFCI, koma kwenikweni ophwanya madera wamba amangoyankha mochulukira komanso mabwalo amfupi.Saziteteza ku arcing mikhalidwe yomwe imatulutsa molakwika komanso nthawi zambiri imachepetsedwa.

Wowonongeka wokhazikika amateteza kutsekereza kwa waya kuti asachuluke, sikunapangidwe kuti azindikire ma arcs oyipa pamabwalo anyumba.Zowonadi, chodulira chigawo chokhazikika chimapangidwa kuti chiziyenda ndi kusokoneza mkhalidwewo ngati muli ndifupikitsa.

MFUNDO 6:Maulendo ambiri a AFCIzikuchitika chifukwa iwondi "kuthamanga kwamphamvu"

Siemens 'Bryant adati adamva nthano iyi kwambiri.“Anthu amaganiza kuti ma arc fault breakers ndi opanda pake chifukwa amangoyenda pafupipafupi.Anthu ayenera kuganiza za izi ngati zidziwitso zachitetezo m'malo mongodumphadumpha.Nthawi zambiri, ophwanya awa amayenda chifukwa amayenera kutero.Akupunthwa chifukwa cha mtundu wina wa zochitika zapaderali. ”

Izi zitha kukhala zowona ndi zotengera "zobaya", pomwe mawaya amalowetsedwa kumbuyo kwa zotengera zomwe sizimazungulira zomangira, zomwe zimapereka kulumikizana kolimba.Nthawi zambiri, eni nyumba akamangirira zotengera zodzaza ndi masika kapena kuzitulutsa mozungulira, nthawi zambiri zimathamangitsa zotengerazo, ndikupangitsa kuti mawaya atuluke, zomwe zimapangitsa kuti arc fault breakers ayende.
