Qhov ntsuas tam sim no ntawm cov yaj tsis sib npaug rau qhov ntsuas tam sim no ntawm lub fuse. Qhov ntsuas tam sim no ntawm cov yaj raug xaiv raws li qhov ntsuas tam sim no ntawm cov cuab yeej tiv thaiv. Qhov ntsuas tam sim no ntawm lub fuse yuav tsum siab tshaj qhov ntsuas tam sim no ntawm cov yaj thiab txiav txim siab hauv kev sib koom tes nrog cov khoom siv hluav taws xob tseem ceeb.
Lub charger pawg fuse feem ntau yog tsim los ntawm peb qhov chaw: yaj, plhaub thiab kev txhawb nqa, ntawm cov uas yaj yog lub ntsiab tseem ceeb los tswj cov yam ntxwv fuse. Cov khoom siv, qhov loj me thiab cov duab ntawm cov yaj txiav txim siab cov yam ntxwv fuse. Melt cov ntaub ntawv yog muab faib ua ob pawg: tsawg melting point thiab siab melting point. Tsawg melting point cov ntaub ntawv xws li txhuas thiab txhuas alloys muaj ib tug tsawg melting point thiab yooj yim rau fuse. Vim lawv qhov kev tiv thaiv loj, qhov sib txawv ntawm qhov loj ntawm cov yaj yog loj, thiab ntau cov hlau vapor yog tsim thaum lub sij hawm fuse. Nws tsuas yog haum rau fusing nrog tsawg tawg peev xwm. ntaus ntawv. Cov ntaub ntawv siab melting point xws li tooj liab thiab nyiaj muaj lub siab melting point thiab tsis yooj yim rau fuse, tab sis vim lawv tsis tshua muaj kev tiv thaiv, lawv tuaj yeem ua rau hauv qhov sib txawv me me dua li qhov qis melting point melts, thiab tsim cov hlau vapor tsawg dua thaum fused, uas yog tsim rau siab tawg cov ntsiab lus. muaj peev xwm fuse. Cov duab ntawm cov yaj yog muab faib ua ob hom: filament thiab ribbon. Hloov cov duab ntawm qhov sib txawv tuaj yeem hloov pauv cov yam ntxwv ntawm lub fuse.
Lub charger pawg fuse muaj qhov cuam tshuam lub sijhawm ncua sijhawm, uas yog, thaum lub sijhawm dhau los yog me me, lub sijhawm fusing ntev; thaum lub overload tam sim no loj, lub sij hawm fusing yog luv. Yog li ntawd, nyob rau hauv ib tug tej yam overload tam sim no ntau yam, thaum tam sim no rov qab mus rau qhov qub, lub fuse yuav tsis tshuab thiab yuav siv tau ntxiv. Fuses muaj ntau yam sib txawv cov yam ntxwv nkhaus, uas tuaj yeem siv rau kev xav tau ntawm ntau hom kev tiv thaiv khoom.
