Lub roj teeb hluav taws xob fuse yog qhov tseem ceeb overcurrent kev tiv thaiv ntaus tshwj xeeb rau roj teeb - powered tshuab. Nws siv ielringicible melting tshuab los muab qib siab tshaj plaws ntawm kev nyab xeeb rau cov ntawv thov tseem ceeb xws li lub zog tshiab thiab lub zog khaws cia. Kev xaiv kom zoo thiab kev thov ntawm cov khoom no yog qhov tseem ceeb los ua haujlwm kom muaj kev nyab xeeb thiab ua haujlwm ruaj khov ntawm tag nrho cov zog hluav taws xob.
Cov tseem ceeb ua haujlwm
Lub luag haujlwm tseem ceeb ntawm lub roj teeb hluav taws xob fuse yog kom xa tau txhim khu kev tiv thaiv kev tiv thaiv ntau dhau. Raws li ib qho kev nyab xeeb tseem ceeb hauv kev tswj hwm roj teeb, nws tau teeb tsa hauv cov koob hauv lub circuit Court. Nyob rau hauv qhov kev tshwm sim ntawm txawv txawv overcurrent los yog luv- kev cuam tshuam rau lub zog, yog li tiv thaiv lub zog roj teeb, thiab cov hluav taws xob hnyav los ntawm kev puas tsuaj. Tseem ceeb tshaj, nws pab tiv thaiv kev nyab xeeb kev nyab xeeb xws li thermal khiav tawm thiab hluav taws kub.
Nws ua haujlwm li cas
Kev ua haujlwm ntawm lub roj teeb lub zog fuse yog raws cov joule cua sov muaj txiaj ntsig ntawm hluav taws xob tam sim no. Nws muaj cov encisely engineered hlau fuse keeb. Raws li kev ua haujlwm ib txwm muaj, thaum lub Circuit Cours tam sim no tseem nyob hauv qab cov nqi fuse tus nqi, cov cua kub tsim tau zoo heev, thiab lub ntsiab lus tseem tsis zoo. Thaum muaj kev sib tw dhau los, kev ua kom sov ua kom ua rau lub caij kom ncav cuag nws lub taw tes melting thiab so. Thaum lub sij hawm luv luv Circuit Court, qhov kev ntxhov siab tam sim no nthuav dav tshav kub yuav luag tam sim ntawd, vaporizing lub caij nyoog thiab cais cov faulty hluav taws xob nyob rau hauv milliseconds.
Cov muaj kev tiv thaiv Cheebtsam
Roj teeb Fais Fuses yog tsim nrog cov hom phiaj tiv thaiv kom meej. Lub hom phiaj tiv thaiv yog lub roj teeb pob nws tus kheej, tiv thaiv kev puas tsuaj sab hauv ntawm tes lossis thermal khiav tawm los ntawm overcuray. Lawv kuj muaj kev tiv thaiv lub hwj chim hluav taws xob ntxiv xws li Inverters, lub zog tswj, thiab DC- dc convers. Ib qho ntxiv, cov fuses xyuas kom meej tias cov hluav taws xob tseem ceeb thiab cov sib txuas tsis dhau, txo qis kev pheej hmoo ntawm cov kev pheej hmoo ntawm theem nrab. Lub hom phiaj kawg yog ua kom muaj kev nyab xeeb tag nrho thiab kev ntseeg siab ntawm lub roj teeb hluav taws xob.
Cov Nta Tseem Ceeb
Roj teeb Fais fab fuses yog cov cim los ntawm ob peb tus cwj pwm tseem ceeb uas ua kom muaj kev tiv thaiv zoo:
Lawv feem ntau yog ib qho - lub sij hawm- Siv cov cuab yeej siv, lav tau kev cia siab tsis muaj kev ntseeg tau yam tsis muaj kev pheej hmoo.
Lawv muaj qhov zoo -} Hais qhov siab siab, feem ntau yog qhov muaj peev xwm cuam tshuam rau kev xyuam xim kom muaj kev txhaum siab los ntawm cov roj teeb.
Nyob ntawm daim ntawv thov, Fused muaj nyob rau hauv Fast {{0} Ua yeeb yam semiconductor (rau kev tiv thaiv soob roj av) thiab sijhawm}}}}}}}}}}}}}}}} Subst ignents se).
