Nkhani Yoti Mumvetsetse AFDD

1. Kodi anArc Fault Protected Circuit Breaker(AFDD)?

Chifukwa cha kukhudzana kosauka kapena kuwonongeka kwazitsulo, "arc yoipa" yokhala ndi mphamvu zambiri komanso kutentha kwakukulu imapangidwa m'dera lamagetsi, zomwe zimakhala zosavuta kuzipeza koma zosavuta kuwononga zipangizo komanso ngakhale moto.
Zochitika zomwe zimakhala ndi ma arcs olakwika
Fault arc, yomwe imadziwika kuti spark yamagetsi, kutentha kwapakati kumakhala kokwera kwambiri, siponji yachitsulo imapezeka, yosavuta kuyambitsa moto.Pamene parallel arc ikuchitika, waya wamoyo ndi waya wosalowerera ndale sizimalumikizana mwachindunji, chifukwa chakuti kukalamba kwa khungu kumataya mawonekedwe kapena kuwonongeka kwa khungu, koma mtunda pakati pa waya wamoyo ndi mzere wosalowerera ndale uli pafupi kwambiri, ndipo wapano. imaphwanya mpweya pakati pa waya wamoyo ndi mzere wosalowerera, ndipo zowala zimatulutsidwa pakati pa waya wamoyo ndi mzere wosalowerera.

2. Mawonekedwe amtundu wocheperako wamagetsi otsika:

1. Mafunde amakono ali ndi phokoso lambiri
2. Pali kutsika kwamagetsi pa fault arc
3. Kuthamanga kwakali pano kumakhala kwakukulu kuposa momwe zimakhalira
4. Kuzungulira kwa theka lililonse pali malo omwe panopa ali pafupi ndi ziro, omwe amatchedwa "dera la zero panopa".
5. Mphamvu yamagetsi yamagetsi ili pafupi ndi rectangle, ndipo kusintha kwa zero zone yamakono ndi yaikulu kuposa nthawi zina, ndipo kuchuluka kwake ndi pamene panopa kupitirira zero.
6. Kulakwitsa kwa arc nthawi zambiri kumakhala kwapang'onopang'ono, kwapakatikati
7. Mafunde amakono ali ndi chisawawa champhamvu
Kupewa ndi kuwongolera moto wamagetsi, womwe ndi ngozi yoyamba yamoto, ikukhala yofunika kwambiri.Arc Fault circuit breaker (AFDD), switchgear yoteteza arc yomwe imalepheretsa moto wamagetsi poyamba, ikufunika.AFDD- arc fault circuit breaker, yomwe imadziwikanso kuti arc fault kuzindikira chipangizo, ndi mtundu watsopano wa zida zodzitetezera.Ikhoza kuzindikira vuto la arc mu dera lamagetsi, ndikudula dera lisanayambe moto wamagetsi, ndikuteteza bwino moto wamagetsi chifukwa cha vuto la arc.

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

Arc fault circuit breaker system, system breaker system, mabungwe osokonekera, makiyi oyendera, ma terminal, chimango cha zipolopolo, monga momwe zimakhalira, mawonekedwe ake amaphatikizanso magetsi odziyimira pawokha, zida zamagetsi zodziwikiratu kuti zizindikiritse vuto wamba ( kuphatikiza microprocessor), kasinthidwe kachitidwe ndi kukonza kutengera PCB nyerere koloni algorithm, Pitirizani kuyesa kwanzeru payekha yamagetsi, tsankho lamba lamagetsi lokhalokha.
A zosiyanasiyana ntchito zazikulu popanda khungu malo kwambiri chitetezo factor
AFDD arc fault circuit breaker imagwiritsidwa ntchito kwambiri m'malo okhala ndi antchito owundana komanso zida zoyaka moto, monga nyumba zogona, malaibulale, zipinda zama hotelo, masukulu ndi nyumba zina zachikhalidwe ndi zaboma.Kuphatikizidwa ndi thupi lake lopepuka komanso losakhwima, m'lifupi mwake ndi 36mm, zomwe zimapulumutsa kwambiri malo a bokosi logawa, ndipo zimagwirizana ndi malo ambiri oyikapo.Imakhala chisankho chabwino kwambiri chopewera kuwunika kwamoto kwamagetsi.
