Ua ntej, ib txwm tam sim no: Ua ntej, peb yuav tsum paub cov fuse uas ntws los ntawm cov khoom siv tam sim no siv hauv cov khoom siv hluav taws xob. Feem ntau peb xav kom txo qhov sib txawv ntawm tus nqi them ua ntej thiab tom qab ntawd xaiv raws li cov hauv qab no: piv txwv li cov tam sim no ib txwm yuav tsum tsawg dua qhov ntsuas tam sim no thiab qhov derating yam khoom ntawm cov khoom.
Thib ob, fuse tam sim no: Raws li UL tus qauv, thaj fuse (fuse) yuav tsum ceev ceev ntawm ob zaug ntawm qhov ntsuas tam sim no. Tab sis feem ntau, txhawm rau kom ntseeg tau tias lub fuse muaj kev ntseeg siab, peb xav kom lub fuse tam sim no ntau dua 2.5 npaug ntawm qhov ntsuas tam sim no. Tsis tas li ntawd, lub sijhawm fusing tseem ceeb heev, tab sis kuj yuav tsum xa mus rau cov chaw tsim khoom' tus qauv fusing cov yam ntxwv los txiav txim siab.
Thib peb, luv-circuit tam sim no: qhov siab tshaj plaws tam sim no tus nqi thaum peb hu rau luv luv-circuit tam sim no. Rau txhua yam ntawm cov fuses, lub peev xwm tawg yog qhov yuav tsum tau ua thaum peb yuav tsum tau ceev faj tsis txhob xaiv cov fuses uas nws cov hluav taws xob tam sim no tshaj qhov muaj peev xwm tawg. Yog tias koj xaiv lub fuse nrog lub peev xwm me me, lub fuse muaj peev xwm ua rau tawg lossis ua rau hluav taws.
Plaub, impulse tam sim no: soj ntsuam cov txiaj ntsig ntawm qhov tam sim no waveform (mem tes tam sim no waveform) nrog tus nqi I2t (joule integral tus nqi) los xam nws lub zog. Qhov loj thiab tus nqi ntawm kev cuam tshuam los ntawm qhov tam sim no thiab cov nyhuv ntawm fuse yog txawv. Influences tus nqi tam sim no ntawm tus nqi I2t I2t ntawm lub fuse, thiab txiav txim siab tus naj npawb ntawm fuse resistances thaum lub sijhawm monopulse inrush tam sim no.
Thib tsib, qhib Circuit Court voltage: qhib Circuit Court voltage feem ntau yuav tsum tau xaiv tsawg tshaj li qhov ntsuas voltage. Piv txwv li, thaum lub ntsuas hluav taws xob yog AC100V DC24V fuse Circuit Court, nws tuaj yeem siv los teeb lub fuse lossis ua rau thaj tsam fuse tawg.
Yog li ntawd, thaum xaiv ib thaj fuse, tsuas yog ua tib zoo mloog rau tsib lub tswv yim no yuav ua rau nws yooj yim rau koj los daws qhov teeb meem ntawm kev xaiv fuse.
