Le Tulaga Manaomia Tulaga Saogalēmū mo Masini Puipuiga galu
O le UL 1449 Standard ua maeʻa faʻatulagaina mo Surge Protective Devices mo le saogalemu ma o le tulaga e manaʻomia mo uma AC puipuiga puipuiga masini (SPDs).
Faʻauiga Aloaia
Tulaga manaʻomia e ufiufi galu puipuia masini (SPDs) fuafuaina mo le faifai pea tapulaʻa o le tumau volitiga galu pei ona faʻamaoti mai i le faʻavae i luga o 50 poʻo 60 Hz eletise eletise e le sili atu i le 1000 V.
Faʻafefea e le Aʻafiaga Aʻafiaga Faʻaalu Puipuiga Masini
- UL 1449 tulaga faʻapitoa faʻataʻotiina eseʻese suʻega e tatau ona pasia e le OEM e faʻamalieina ai le usitaʻia
- Standard SPDs tatau ona i ai UL 1449 tusi faʻamaonia e ausia ai le saogalemu tulaga faʻapitoa mo maketi faapitoa
O a SPD Ituaiga e ufiufi

Faailoga Manaʻomia
Ina ua maeʻa Maua UL tusi pasi, gaosi oloa ave le matafaioi e faʻamalieina tulaga faʻatauaina. Uma SPDs aofia manino ma tumau manaʻoga faʻailoga e mautinoa ai fofo e te filifilia feiloaʻi UL 1449.
- Igoa gaosi oloa
- Numera lisi
- SPD Ituaiga
- Faʻailogaina eletise
- Faʻailoga o loʻo iai nei (I) faʻailoga
- Tapulaʻa maualuga faʻaauau volitiga faʻagaioiga (MCOV)
- Fua faatatau puipuiga volitiga (VPR)
- Fua faʻatapulaʻaina volitiga (MLV)
- Aso poʻo le vaitaimi o le gaosiga
- Fuafua matagaluega taimi nei puʻupuʻu (SSCR)
Ituaiga 4 vaega faʻapotopotoga ma Ituaiga 5 SPDs manaʻomia MLV, MCOV, faʻagaioiga uila, ma I faʻavasegaina. Mo Ituaiga 5 SPDs nei faʻavasegaina mafai ona avatua i faʻamaumauga pepa.
Faʻaupuga o Upu Autu
- Sese nei - Taimi nei mai le eletise eletise e tafe i totonu o se auala puʻupuʻu
- Tapulaʻa maualuga faʻaauau volitiga (MCOV) - Tapulaʻa maualuga aofaʻi o voltage e mafai ona faʻaauau faʻaauau i SPD
- Fua faʻatapulaʻaina voltage - Ole aofaʻi maualuga ole voltage e fuaina pe a faʻaaogaina I totonu
- Nofoaga o loʻo faʻateʻa ai nei (I) - Tulaga taua o le taimi nei (8 x 20 galu foliga) faʻamalosia i totonu o le SPD 15 taimi (SPD tatau ona tumau faʻagaioiga)
- Laititi eletise faʻaaogaina - Masani AC paoa voltage o le polokalama
- Volosa (Vn) - DC voltage fuaina i luga ole SPD pe a tafe 1mA
- Fuafua matagaluega taimi nei puʻupuʻu (SCCR) - Talaʻiga o le SPD e tatalia ai le faʻalauiloaina o le taʻamilosaga puʻupuʻu mai le eletise
- Fua faatatau puipuiga volitiga (VPR) - Voltage rating filifilia mai se lisi o mea e sili ona taua pe a fai o se tuʻufaʻatasiga galu o 6kV 3kA e faʻaaogaina
