Arc Fault Detection Devices

Kodi ma arcs ndi chiyani?

Arcs ndizomwe zimatuluka m'madzi a m'magazi chifukwa cha magetsi omwe amadutsa mu sing'anga yosasinthika, monga mpweya.Izi zimachitika pamene magetsi amayatsa mpweya mumlengalenga, kutentha kopangidwa ndi arcing kumatha kupitilira 6000 ° C.Kutentha kumeneku ndi kokwanira kuyatsa moto.

Zomwe zimayambitsa ma arcs?

Arc imapangidwa pamene magetsi akudumpha kusiyana pakati pa zida ziwiri zoyendetsera.Zomwe zimayambitsa ma arcs zimaphatikizapo, kulumikizidwa kovala mu zida zamagetsi, kuwonongeka kwa kutsekereza, kusweka kwa chingwe ndi kulumikizana kotayirira, kutchulapo zochepa.

Chifukwa chiyani chingwe changa chiwonongeka ndipo chifukwa chiyani pangakhale zoyimitsa?

Zomwe zimayambitsa kuwonongeka kwa chingwe ndizosiyana kwambiri, zina mwazomwe zimayambitsa zowonongeka ndi izi: kuwonongeka kwa makoswe, zingwe zophwanyidwa kapena kutsekeredwa ndi kusamalidwa bwino komanso kuwonongeka kwa kutsekemera kwa chingwe chifukwa cha misomali kapena zomangira ndi kubowola.

Malumikizidwe otayirira, monga tanenera kale, amapezeka nthawi zambiri pakutha kowonongeka, pali zifukwa ziwiri zazikuluzikulu za izi;choyamba ndi olakwika kumangitsa kugwirizana mu malo oyamba, ndi chifuniro chabwino padziko lapansi anthu ndi anthu ndipo amalakwitsa.Pomwe kukhazikitsidwa kwa ma torque screwdrivers mu dziko la kukhazikitsa magetsi kwasintha izi zolakwika zitha kuchitikabe.

Njira yachiwiri yotayirira yotayirira imatha kuchitika chifukwa cha mphamvu yamagetsi yamagetsi yomwe imapangidwa ndikuyenda kwamagetsi kudzera mwa ma conductor.Mphamvu imeneyi pakapita nthawi idzapangitsa kuti maulumikizano asungunuke pang'onopang'ono.

Kodi Arc Fault Detection Devices ndi chiyani?

Ma AFDD ndi zida zodzitchinjiriza zomwe zimayikidwa m'magawo ogula kuti ateteze ku zolakwika za arc.Amagwiritsa ntchito ukadaulo wa microprocessor kusanthula mawonekedwe amagetsi omwe amagwiritsidwa ntchito kuti azindikire siginecha zachilendo zomwe zingatanthauze arc padera.Izi zidzadula mphamvu kudera lomwe lakhudzidwa ndipo zitha kuteteza moto.Amakhudzidwa kwambiri ndi ma arcs kuposa zida zodzitchinjiriza wamba.

Kodi ndikufunika kukhazikitsa Arc Fault Detection Devices?

Ma AFDD ndi oyenera kuganiziridwa ngati pali chiopsezo chowonjezereka cha moto, monga:

• Malo okhala ndi malo ogona, mwachitsanzo nyumba, mahotela, ndi ma hostel.

• Malo omwe ali ndi chiopsezo cha moto chifukwa cha chikhalidwe cha zinthu zokonzedwa kapena zosungidwa, mwachitsanzo masitolo a zinthu zoyaka moto.

• Malo okhala ndi zida zomangira zoyaka, mwachitsanzo nyumba zamatabwa.

• Nyumba zoyatsira moto, mwachitsanzo nyumba zofolera ndi udzu ndi nyumba zomangidwa ndi matabwa.

• Malo omwe ali pachiwopsezo cha zinthu zomwe sizingasinthidwe, mwachitsanzo malo osungiramo zinthu zakale, nyumba zolembedwa ndi zinthu zamtengo wapatali.

Kodi ndikufunika kukhazikitsa AFDD padera lililonse?

Nthawi zina, zingakhale zoyenera kuteteza madera ena omaliza osati ena koma ngati chiwopsezocho chimachitika chifukwa cha zida zofalitsa moto, mwachitsanzo, nyumba yokhala ndi matabwa, kukhazikitsa konse kuyenera kutetezedwa.
