Nkhani Yokuthandizani Kumvetsetsa AFDD

1. Kodi ndi chiyaniChotsukira Dera Chotetezedwa ndi Arc Fault(AFDD)?

Chifukwa cha kuwonongeka kosakhudzana kapena kutetezedwa bwino kwa zinthu zotenthetsera, "mzere woipa" wokhala ndi mphamvu zambiri komanso kutentha kwambiri umapangidwa mu dera lamagetsi, lomwe silipezeka mosavuta koma limayambitsa kuwonongeka kwa zida komanso ngakhale moto.
Zochitika zomwe zimakhala ndi ma arcs olakwika
Cholepheretsa, chomwe chimadziwika kuti magetsi, kutentha kwapakati kumakhala kwakukulu kwambiri, chitsulo chimatuluka, zomwe zimapangitsa kuti moto uyambe mosavuta. Cholepheretsa chikachitika, waya wamoyo ndi waya wa neutral sizimalumikizana mwachindunji, chifukwa khungu loteteza kutentha limataya mawonekedwe a kutetezera kutentha kapena kuwonongeka kwa khungu, koma mtunda pakati pa waya wamoyo ndi mzere wa neutral uli pafupi kwambiri, ndipo mphamvu yamagetsi imaphwanya mpweya pakati pa waya wamoyo ndi mzere wa neutral, ndipo ma spark amatuluka pakati pa waya wamoyo ndi mzere wa neutral.

2. Makhalidwe wamba a arc yolakwika yamagetsi otsika:

1. Mafunde apano ali ndi phokoso lalikulu la ma frequency apamwamba
2. Pali kutsika kwa magetsi pa arc ya cholakwika
3. liwiro la kukwera kwa magetsi nthawi zambiri limakhala lalikulu kuposa momwe zinthu zilili
4. Gawo lililonse la theka la kuzungulira limakhala ndi dera lomwe mphamvu yamagetsi imakhala pafupi ndi zero, lomwe limatchedwa "dera la zero lamagetsi".
5. Mafunde a magetsi ali pafupi ndi rectangle, ndipo kusintha kwa magetsi mu dera la zero lamakono ndi kwakukulu kuposa nthawi zina, ndipo nthawi yayitali ndi pamene magetsi ali pamwamba pa zero.
6. Mzere wolakwika nthawi zambiri umakhala wosakhazikika, wosinthasintha
7. Mafunde apano ali ndi kusakhazikika kwamphamvu
Kupewa ndi kuwongolera moto wamagetsi, womwe ndi ngozi yoyamba ya moto, kukukhala kofunika kwambiri.Chosweka cha Arc Fault Circuit (AFDD), chosinthira magetsi chomwe chimateteza moto wamagetsi chikufunika poyamba.AFDD— chothyola ma arc fault circuit breaker, chomwe chimadziwikanso kuti chipangizo chozindikira ma arc fault, ndi mtundu watsopano wa zida zodzitetezera. Chimatha kuzindikira ma arc fault mu arc circuit yamagetsi, ndikudula ma arc circuit moto usanayambe, ndikuletsa moto wamagetsi womwe umachitika chifukwa cha ma arc fault.

3. Kodi malo ogwiritsira ntchito a AFDD arc fault circuit breaker ndi ati?

Njira yogwirira ntchito yophwanya dera la Arc fault circuit, circuit breaker system, mabungwe otseguka, makiyi owunikira, ma terminal blocks, chimango cha chipolopolo, monga kapangidwe kake, kapangidwe kake kamakhala ndi magetsi odziyimira pawokha, zida zamagetsi zamagetsi zodziwira dera lodziwika bwino (kuphatikiza microprocessor), kasinthidwe ka dongosolo ndi kukonza kutengera algorithm ya PCB nyerere, Pitirizani kuyesa kwamagetsi kwanzeru, kusankhana kwamagetsi kwapadera.
Mitundu yosiyanasiyana ya ntchito zazikulu popanda malo akhungu chitetezo china
Chotsekera ma circuit cha AFDD arc chimagwiritsidwa ntchito kwambiri m'malo okhala ndi antchito ochulukirapo komanso zinthu zopangira moto, monga nyumba zogona, malaibulale, zipinda zamahotela, masukulu ndi nyumba zina zachikhalidwe ndi za anthu onse. Kuphatikiza ndi thupi lake lopepuka komanso lofewa, m'lifupi mwake ndi 36mm yokha, zomwe zimasunga kwambiri malo a bokosi logawa, ndipo zimagwirizana ndi malo ambiri oyika. Chimakhala chisankho chabwino kwambiri popewa kuyang'anira moto wamagetsi.
