Ushicilelo lwe-UL 1449 lwe-4-Ukukhuphela mahala
Umgangatho ofunekayo woKhuseleko kwezixhobo zoKhuseleko lweSurge
Umgangatho osandula ukukhutshwa we-UL 1449 oMiselweyo wezixhobo zokuKhusela eziKhuselekileyo kwaye ngumgangatho okhethiweyo wazo zonke izixhobo zokukhusela i-AC (SPDs).
Inkcazo ngokusemthethweni
Izidingo ezigubungela izixhobo zokukhusela (ii-SPDs) eziyilelwe ukuthintela okuphindaphindayo kwamandla ombane njengoko kucacisiwe kumgangatho kwiisekethi zombane ezingama-50 okanye ezingama-60 ezingadluli kwi-1000 V.
Zichaphazeleka njani iiMigangatho yoKhuseleko lwezixhobo
- Umgangatho we-UL 1449 ucacisa iimvavanyo ezahlukeneyo ekufuneka zigqithwe zii-OEMs ukubanga ukuthotyelwa
- Ii-SPD eziqhelekileyo kufuneka zibe nesiqinisekiso se-UL 1449 ukuhlangabezana nemigangatho yokhuseleko kwiimarike ezithile
Zeziphi iintlobo ze-SPD eziGutyungelweyo

Ukuvavanya kubalulekile
Kubalulekile kuluhlu lwe-UL kuvavanyo olusemgangathweni. Le tafile inika iinkcukacha ngemigaqo yovavanyo lwendibano yesi-4 kunye nohlobo lwesihlanu lweendibano ze-SPD.

Okufunekayo
Emva kokufumana isatifikethi se-UL, umenzi uthatha uxanduva lokuhlangabezana nemigangatho ngokungathí sina. Zonke ii-SPD zibandakanya ukumakishwa okucacileyo nokusisigxina okufunekayo ukuze kuqinisekiswe ukuba izisombululo ozikhethayo ziyahlangana ne-UL 1449.
- Igama lomenzi
- Inombolo yekhathalogu
- Uhlobo lwe-SPD
- Ukulinganiswa kombane
- Inqanaba lokukhutshwa ngegama ngoku (ngaphakathi)
- Ubuninzi obuqhubekayo bokusebenza kwamandla ombane (MCOV)
- Inqanaba lokhuselo lwevolthi (VPR)
- Ukulinganisa umda wevolthi (MLV)
- Umhla okanye ixesha lokwenziwa
- Ukulinganiswa okwangoku kwesekethe (SSCR)
Chwetheza iindibano zecandelo le-4 kunye nohlobo lwe-5 SPDs ezifuna i-MLV, i-MCOV, i-voltage yokusebenza, kunye nokulinganisa. Kwii-5 ze-SPDs ezi zilinganiso zinokubonelelwa kumaphepha edatha.
Iglosari yamaGama aPhambili
- Ityala langoku -Ngoku ukusuka kwinkqubo yamandla ehamba kwisekethe emfutshane
- Ubuninzi bevolthi yokusebenza eqhubekayo (MCOV) Ubuninzi bevolthi enokusetyenziswa ngokuqhubekayo kwi-SPD
- Ukulinganisa umda wevolthi Ubungakanani obukhulu bevolthi yokulinganisa xa kusenziwa i-In
- Ukukhutshwa ngegama ngoku (ngoku) Ixabiso lencopho yangoku (8 x 20 imilo yokujija) eqhutywa ngamaxesha e-SPD 15 (SPD kufuneka ihlale isebenza)
- Umbane osebenzayo ngegama - Amandla ombane aqhelekileyo esixokelelwano
- Amandla ombane (Vn) Umbane we-DC ulinganiswe kwi-SPD xa i-1mA ihamba
- Ukulinganiswa okwangoku kwesekethe (SCCR) Ukulungela i-SPD ukumelana nesekethe emfutshane ebhengeziweyo evela kumthombo wamandla
- Inqanaba lokhuselo lwevolthi (VPR) Ixabiso leVolthi ekhethiweyo kuluhlu lwamaxabiso akhethiweyo xa kusenziwa iliza elidibeneyo le-6kV 3kA
