Kutulutsa kwa UL 1449 4th-Free Download
Muyeso Wofunikira Wachitetezo pazida Zotetezera za Surge
Ma UL 1449 omwe atulutsidwa kumene a Standard for Surge Protect Devices for chitetezo ndipo ndiyomwe amakonda zida zonse za AC zoteteza (SPDs).
Tanthauzo Lovomerezeka
Zofunikira zomwe zimaphimba zida zodzitetezera (SPDs) zopangidwira kuchepetsa mobwerezabwereza ma voltage osakhalitsa monga amafotokozedwera muyezo wama 50 kapena 60 Hz magetsi osapitirira 1000 V.
Momwe Zovuta Zomwe Zimakhudzira Zida Zotetezera
- Mulingo wa UL 1449 umafotokozera mayesero osiyanasiyana omwe ma OEM amayenera kudutsa kuti adzitsatire
- Ma SPD oyenera ayenera kukhala ndi UL 1449 certification kuti akwaniritse chitetezo pamisika ina

- Dzina la wopanga
- Nambala ya Catalog
- Mtundu wa SPD
- Mavoti amagetsi
- Mwadzina kutulutsa kwamakono (In)
- Kutalika kwakukulu kwamagetsi (MCOV)
- Kuteteza kwa Voltage (VPR)
- Kuyeza malire amagetsi (MLV)
- Tsiku kapena nthawi yopanga
- Chiwerengero chachifupi chamakono (SSCR)
Mtundu wachinayi wamisonkhano yayikulu ndi mtundu wa 4 SPDs umafuna MLV, MCOV, magetsi, ndi ma ratings. Kwa mtundu wa 5 SPDs mavoti awa atha kuperekedwa m'mapepala azidziwitso.
Zakumapeto za Mawu Ofunika
- Vuto lamakono - Zamakono kuchokera kumagetsi omwe amayenda munthawi yochepa
- Zolemba malire mosalekeza opaleshoni voteji (MCOV) - Kuchuluka kwamphamvu yamagetsi yomwe ingagwiritsidwe ntchito mosalekeza ku SPD
- Anayesa kuchepetsa mphamvu zamagetsi - Kutalika kwakukulu kwamagetsi kuyesedwa mukalowa mu In
- Mwadzina kumaliseche panopa (In) - Mtengo wamtengo wapatali wamakono (8 x 20 mawonekedwe mawonekedwe) oyendetsedwa kudzera mu SPD nthawi 15 (SPD iyenera kukhalabe yogwira)
- Mwadzina voteji opaleshoni - Mphamvu yamagetsi yama AC yamtunduwu
- Mwadzina voteji (Vn) - DC voltage yoyezedwa kudutsa SPD pomwe 1mA ikuyenda
- Chiwerengero chachifupi chamakono (SCCR) - Kukwanira kwa SPD kuti mupirire mayendedwe afupipafupi kuchokera ku magetsi
- Kuteteza kwa Voltage (VPR) - Voteji yotsimikizika yomwe yasankhidwa pamndandanda wazomwe mungakonde mukamagwiritsa ntchito 6kV 3kA
