Ntu 2: Cov Qauv Kev Xaiv Tseem Ceeb
Xaiv txoj cai 3216 fuse yog ntau tshaj li kev sib txuam tam sim no ntaus nqi. Ib txoj hauv kev los tiv thaiv thaiv cov teb ua tsis tiav thiab ua kom muaj kev tsim qauv zoo.
Kauj ruam 1: Txhais cov haujlwm ib txwm muaj
1. Kev ua haujlwm ib txwm tam sim no (i ~ op ~):Txheeb xyuas qhov siab kawg txuas ntxiv mus rau lub Circuit Court yuav kos nyob rau hauv ib txwm muaj mob.
Txoj Cai Xaiv:Lub fuse's rated tam sim no (i ~ n ~) yuav tsum muaj kwv yees li 20 -}}} dua i ~ op ~ rau account rau kev hloov me me thiab zam kev nkees. Piv txwv li, yog tias koj lub xeev khov kho tam sim no yog 1A, pib los ntawm saib ntawm 1.25A lossis 1.5A fuse.

2. Kev khiav hauj lwm voltage (v ~ op ~):
Txoj Cai Xaiv:Lub fuse qhov ntsuas hluav taws xob yuav tsum yogntau duaLub kaw lus qhov siab tshaj plaws, suav nrog cov kev hloov pauv. Rau 12V system, system, 32v lossis 63v fuse yog qhov tsim nyog. Rau 48v system, 63v lossis 125v fuse yog xav tau.
Kauj ruam 2: Txheeb xyuas kev ua txhaum & Inrush mob
Nov yog qhov uas muaj ntau tus qauv tsim.
1. Inrush tam sim no (mem tes thauj khoom):Koj lub Circuit Court puas muaj kev pib qhib? (piv txwv li, lub cev muaj zog pib, capacitor them).
Nkaus:Yog tias muaj, koj yuav luag yeej xav tauLub sij hawm - lag (qeeb - tshuab tshuab)fuse. Txheeb xyuas lub fuse kuv ^ 2 ^ t cia - los ntawm tus nqi tiv thaiv koj mem tes profile ntawm cov ntaub ntawv. Lub fuse yuav tsum tiv thaiv cov mem tes yam tsis muaj kev txwv.
2. Txhaum Tam Sim No:Dab tsi yog qhov siab tshaj plaws muaj peev xwm luv - Circuit Court tam sim no koj lub zog tuaj yeem xa tau?
Nkaus:Xyuas kom meej lub fuseBreaking muaj peev xwmtshaj tus nqi no. Yog tias koj cov khoom siv fais fab tuaj yeem xa 100A rau hauv luv luv, koj lub fuse yuav tsum tau ntsuas kom cuam tshuam tsawg kawg uas muaj kev nyab xeeb ntau.
Kauj ruam 3: Xav txog ib puag ncig ib puag ncig
1. Ambient kub:Fuses yog rhiab rau qhov kub. Ntawm qhov chaw siab tshaj plaws, lawv yuav qhib ntawm qis dua tam sim no.
Nkaus:Tham nrog txoj kev nkhaus ua ke hauv lub datasheet. Lub fuse rau 2a ntawm 25℃tsuas yog tsim nyog rau 1.6a ntawm 70 degree.
2. Board chaw & Mounting:Paub meej tias 3216 hneev taw haum koj txoj kev teeb tsa. Nco ntsoov nws yog ob -} davhlau ya nyob twg.
Kauj ruam 4: Kev pov thawj zaum kawg & Kev Nyab Xeeb
1. Ntawv sauNtawv pov thawj:Puas yog koj cov khoom xav tau UL, TUV, lossis lwm lub koomhaum kev pom zoo? Xaiv cov fuse uas ua cov ntawv pov thawj tsim nyog.
2. Cov tswv yim fuseesy: Tso lub fuse Mas -}}}}}} Nws nyob rau ntawm lub hwj huam kev tsheb ciav hlau tam sim tom qab kev sib txuas. Qhov no tiv thaiv txhua qhov dej ntws hauv cheebtsam hauv qab.
