1.Nyob Tam Sim No: Ua ntej peb yuav tsum paub qhov loj me me tam sim no uas ntws los ntawm lub fuse hauv Circuit Court siv.
Feem ntau peb yuav tsum teeb tsa kev txo qis ua ntej, thiab tom qab ntawd xaiv raws li hauv paus ntsiab lus hauv qab no: uas yog, qhov ib txwm muaj tam sim no yuav tsum tsawg dua li cov khoom lag luam ntawm qhov ntsuas tam sim no thiab txo qis coefficient.
2.Fuse Tam Sim No: Raws li UL cov lus qhia tshwj xeeb, lub fuse yuav tsum tau fused sai ntawm qhov ntsuas tam sim no ob zaug. Feem ntau, txawm li cas los xij, txhawm rau kom ntseeg tau tias fuse ntseeg tau, peb pom zoo tias fuse tam sim no yuav tsum ntau dua 2.5 npaug ntau dua li qhov ntsuas tam sim no.
Ib qho ntxiv, lub sijhawm fuse yog qhov tseem ceeb, tab sis kuj yuav tsum xa mus rau fuse tus yam ntxwv yam ntxwv uas muab los ntawm cov chaw tsim khoom los txiav txim.
3.Qhib Circuit Voltage: qhib qhov hluav taws xob qhov hluav taws xob feem ntau yuav tsum raug xaiv kom tsawg dua qhov ntsuas hluav taws xob.
Piv txwv li, thaum lub fuse nrog ntsuas qhov ntsuas ntawm dc24v tau siv hauv AC100v Circuit Court, nws tuaj yeem ua rau tawg lossis tawg lub fuse.
4.Siv luv-Circuit tam sim no: Tus nqi tam sim no siab tshaj plaws peb ntws thaum lub Circuit luv luv-hu ua luv-Circuit tam sim no. Rau ntau yam fuses, cov peev txheej tawg tawg tau teev tseg, thiab peb yuav tsum tau ceev faj tsis txhob ua kom luv luv-Circuit tam sim no muaj peev xwm ntsuas tau thaum xaiv lub fuse.
Yog tias lub fuse nrog lub peev xwm hluav taws xob tawg me me raug xaiv, nws yuav ua txhaum lub fuse lossis ua rau hluav taws kub.
5.Impact Tam sim no: Cov yoj (pulse tam sim no waveform) rau kev soj ntsuam ntawm qhov cuam tshuam tam sim no tau siv los laij nws lub zog siv tus nqi I2T (Joule ib qho muaj nuj nqis). Qhov cuam tshuam tam sim no sib txawv hauv qhov loj thiab zaus, thiab cov nyhuv ntawm fuse sib txawv. Qhov piv ntawm i2t tus nqi ntawm qhov cuam tshuam tam sim no rau fuse i2t tus nqi ntawm ib tus mem tes nkaus xwb txiav txim siab tus naj npawb ntawm lub sijhawm fuse tiv taus rau qhov cuam tshuam tam sim no.
