Yuav xaiv Fuse li cas?
Kev ntsuas fuse=(watts / volts) x 1.25
1. Xaiv lub fuse, zoo li lub sijhawm qeeb kev fuses rau sab hauv thiab kev ua haujlwm sai fuses rau tiv taus lub qub.
2. Sau lub zog (watts) ntawm cov khoom siv - feem ntau los ntawm cov ntawv siv khoom siv,
3. Sau qhov ntsuas voltage. Qhov ntsuas hluav taws xob yuav tsum ntau dua qhov hluav taws xob Circuit Court rau kev tiv thaiv kom zoo ntawm lub cuab yeej.
4. Siv qhov kev ntaus nqi siab tshaj plaws tom qab tshaj plaws. Piv txwv, yog tias qhov suav fuse ntsuas yog 8.659 amps, yog li rau qhov no peb yuav siv 9 amp fuse.
Cov yam ntxwv ntawm Fuses
Muaj qee qhov tseem ceeb ntawm cov fuses hauv hluav taws xob thiab hluav taws xob uas muaj raws li hauv qab no: -
Ntsuam Xyuas Tam Sim No:Cov kev ua haujlwm tsis tu ncua ntawm cov nyiaj tau txais tam sim no tuav lub fuse tsis muaj melting nws yog ua tus ua raws li kev ntsuas tam sim no. Nws yog lub peev xwm nqa khoom tam sim no, uas ntsuas hauvAmperes. Qhov no yog cov yam ntxwv thermal.
Tam sim no (xinesmas)=75% Tam sim no (ntsuam xyuas)
Ntsuas Kev Ntsuas:Hauv qhov yam ntxwv no, qhov voltage txuas hauv series nrog fuse tsis nce voltage kev ntsuas. piv txwv li,
V (fuse)> V (qhib ckt)
I2t Ntsuas:Qhov no yog tus nqi ntawm lub zog uas nqa los ntawm fuse keeb whenthere yog qhov txhaum hluav taws xob lossis qee lub sijhawm luv luv tshwm sim. Nws ntsuas lub zog cua sov (lub zog vim los ntawm ntws tam sim no) ntawm fuse& nws yog tsim thaum fuse tau tshuab.
Kev cuam tshuam los yog tawg lub peev xwm:Nws yog qhov ntsuas qhov siab tshaj plaws ntawm tam sim no yam tsis muaj kev cuam tshuam los ntawm lub fuse yog paub tias tawg lossis cuam tshuam kev muaj peev xwm ntawm lub fuse.
Rhuav tshem tau> siab kawg ntsuas qhov hluav taws xob
Rhuav tshem tau< luv="" ckt="" tam="" sim="">
Tus Ntsuas Hluav Taws Xob: Thaum ntau dhau tam sim no ntws, lub fuse caij melts thiab qhib lub Circuit Court. Vim tias qhov hloov pauv no thiab qhov voltage poob yuav ua qis dua.
Ntsig Kub: Hauv qhov no, kev ua haujlwm kub yuav siab dua; yog li qhov ntsuas tam sim no yuav tsawg dua, yog li cov fuse melts.
Fuse cov yam ntxwv
Lub teeb ntsuas no pom qhov ntsuas kub piv rau lub peev xwm tam sim no ntawm lub fuse. Hauv cov txheej txheem no, ntawm qhov chaw uas peb txoj kab sib ntsib ntawm 25 degrees Celsius, qhov tam sim no nqa lub peev xwm ntawm cov fuse yuav yog 100% thiab tom qab qee lub sijhawm muaj peev xwm tam sim no txo ntawm qeeb fuse, nws tseem yuav txo txog li 82% ntawm 65 degrees C. Qhov no ua rau pom tias, nce hauv qhov kub thiab txias yuav txo qis dua qhov nqa khoom tam sim no ntawm lub fuse.
Kev faib tawm ntawm Fuses
Tam sim no peb tab tom tham txogntau hom kev tsim txomCov. Lawv tau muab faib ua ob ntu AC Fuses& DC Fuses. Ntxiv mus, lawv tau muab faib ua ntau pawg tau muab rau hauv cov flowchart hauv qab no: -
