Nyob rau hauv huab huab ib puag ncig zoo li siab thiab tsawg kub, qhov kev ua tau zoo ntawm fuses hloov pauv ntawm cov kev hauv qab no:
Qhov Kub Ib puag ncig
Rated Righ Tam Sim No
Kev kub siab nce kev nce qib tiv thaiv cov khoom siv fuse. Raws li Joule txoj cai (q=i2rt), cov cua sov tsim nce thaum cov tam sim no tas li. Txhawm rau tiv thaiv thaum ntxov melting vim overheating, qhov ntsuas tam sim no ntawm fuse tsawg. Piv txwv li, lub fuse nrog 10a rated tam sim no ntawm ib txwm muaj ambient kub yuav kov ib ncig ntawm 8a nyob rau ib puag ncig kub siab.
Lub sijhawm luv luv fus
Kev kub siab kub ua kom nrawm dua cov cua sov ntxiv hauv cov khoom siv fuse. Thaum qhov tam sim no mus txog ib qib kev txiav txim siab, lub fuse mus txog nws lub ntsej muag melting ntau dua sai, yog li txo lub sijhawm fused. Piv txwv li, thaum nws yuav siv sijhawm 10 vib nas this rau 15a txhawm rau tshuab lub fuse ntawm qhov kub thiab txias, nyob rau hauv lub siab - chaw, nws tsuas yog siv 5 vib nas this.
Nrov laus
Kev ntsuas kub siab rau cov tshuaj lom neeg ntau xws li oxidation hauv cov ntawv fuse cov khoom siv. Qhov no ua rau muaj kev poob qis zuj zus hauv nws cov khoom siv hluav taws xob thiab hluav taws xob, ua kom pom cov txheej txheem laus. Raws li ib tug tshwm sim, lub fuse yog ntau tshaj qhov tsis ua haujlwm txawm tias nyob rau hauv kev ua haujlwm ib txwm muaj.
Tsawg Ib puag ncig kub
Muaj peev xwm nce nyob rau hauv rated tam sim no
Ntawm tsawg kub, qhov tiv taus ntawm cov khoom fuse feem ntau txo qis. Rau qee qhov, qhov no tso cai rau qhov tseem ceeb tshaj plaws kom dhau yam tsis muaj ntau lub tshav kub ntau heev uas yuav ua rau yaj. Thiaj li, qhov ntsuas tam sim no yuav nce me ntsis piv rau qhov ntsuas kub ib txwm, txawm hais tias qhov kev hloov no yog tus menyuam yaus.
Ncua sij hawm fus
Hauv qhov tsawg - qhov chaw fuse ib puag ncig, cov khoom siv fuse dispipates tshav kub dua sai dua, qeeb qeeb kev sib tw. Thaum muaj ntau dhau los yog luv luv - Circuit Court tam sim no tshwm sim, nws siv sijhawm ntev dua rau cov fuse kom ncav cuag nws lub poelting. Piv txwv li, ib xyoos tam sim no melts lub fuse hauv 3 vib nas this thaum qhov ntsuas kub ib txwm yuav noj 5 feeb ntev dua los ua qhov chaw qis - ntsuas kub.
Nce brittleness
Tej yam fuse cov ntaub ntawv ua nkig thiab poob todness ntawm tsawg kub. Qhov no ua rau cov fuse ntau tau ua rau tawg thaum raug rau kev co lossis cuam tshuam, yog li cuam tshuam nws txoj kev tiv thaiv ib txwm muaj. Ib qho ntxiv, tsawg kub tuaj yeem ua rau lub fuse rau cov ntsiab lus sib txuas rau cov lus cog lus, nce rau kev sib chwv rau hauv ib cheeb tsam, uas cuam tshuam rau kev ua haujlwm fuse.
