Lub qhov mount fuse zoo li tus kheej - tus neeg saib xyuas Circuit Court. Thaum qhov tam sim no siab dhau lawm, nws txiav txim siab yaj nws tus kheej, txiav tawm lub voj voog thiab tiv thaiv cov khoom siv hluav taws xob kim dua.
I. Nws yog dab tsi? Xav txog tej yam me me, tiaj tus cuboid (zoo li ib daim ntawm cov khoom qab zib sesame) nrog cov hlau electrodes ntawm ob qho kawg, siv los txhuam rau hauv Circuit Court board. Qhov no yog qhov chaw mount fuse.Nws cov yam ntxwv yog: me me: Raws li me me li cov noob hnav los yog cov nplej nplej, haum rau cov khoom siv hluav taws xob niaj hnub no. Surface Mount: Soldered ncaj qha mus rau saum npoo ntawm lub rooj tsav xwm Circuit Court, siv qhov chaw me me thiab tsim nyog rau kev siv tshuab ua haujlwm. Pov tseg: Thaum melted, nws tsis tuaj yeem rov qab los thiab yuav tsum tau hloov. II. Nws siv qhov twg?
Yuav luag txhua yam khoom siv hluav taws xob niaj hnub uas xav tau kev tiv thaiv kev tiv thaiv hluav taws xob tuaj yeem pom nrog nws. Nov yog qee yam uas koj tiv thaiv txhua hnub:
1. Smartphones & Tablets: Tiv thaiv cov chips ntawm lub motherboard thiab lub roj teeb them hluav taws xob.
2. Laptops & Desktops: Tiv thaiv cov khoom tseem ceeb xws li motherboard, hard drive, thiab USB ports.
3. Smart TVs & Monitors
4. Cov Khoom Siv Hauv Tsev: Xws li lub tshuab cua txias tswj boards, microwave qhov cub circuit boards, ntxhua khaub ncaws lub ntsiab tswj vaj huam sib luag, thiab lwm yam.
5. Automotive Electronic Systems: Central control screens, on -board computers, sensors, etc.
6. Fais fab Ntug Dej & Ntau Lub Hwj Chim Fais Fab
Cias muab, nws yog "tus saib xyuas tsis pom" ntawm cov khoom siv hluav taws xob niaj hnub no.
III. Nws ua haujlwm li cas?
(Core Principple)
Peb tuaj yeem nkag siab qhov no siv qhov piv txwv zoo heev:
Xav txog lub voj voog raws li txoj kev loj, thiab tam sim no raws li cov tsheb taug kev ntawm nws. Qhov saum npoo mount fuse zoo li ib"qhov siab / qhov hnyav txwv qhov ntsuas" ntawm txoj kev loj no.
Qhov xwm txheej (Normal Current):
Kev khiav tsheb khiav (tam sim no) ntawm txoj kev yog du thiab nyob rau hauv qhov siab txwv. Qhov "checkpoint" (fuse) no nyob ntsiag to, tso cai rau txhua lub tsheb hla tsis muaj kev cuam tshuam rau lub voj voog.
Qhov xwm txheej txawv txav (ntau dhau tam sim no, xws li luv Circuit Court lossis overload):
Tam sim ntawd, lub tsheb thauj khoom hnyav heev (ntau dhau tam sim no) lossis tawm - ntawm - tswj kev khiav tsheb (luv luv luv tam sim no) rushes mus rau qhov chaw kuaj xyuas. Qhov "checkpoint," tsim raws li cov qauv, tsis tuaj yeem tiv taus qhov cuam tshuam loj.
Yog li, txhawm rau tiv thaiv kev puas tsuaj los ntawm kev kis mus rau thaj chaw tseem ceeb dua tom qab (cov khoom siv hluav taws xob kim), nws tau xaiv "tus kheej- kev puas tsuaj"- melting tam sim ntawd thiab tawg (lub cev kub hnyiab tawm), txiav tag nrho txoj kev. Yuav ua li cas tom qab fais fab tuag? Qhov tawm - ntawm - tswj kev khiav tsheb (ntau dhau tam sim no) raug tso tseg. Lub nroog tom qab (koj lub xov tooj motherboard, lub computer nti) muaj kev nyab xeeb. Tab sis qhov chaw kuaj xyuas (fuse) kuj ua tsis tiav; Circuit Court raug thaiv tag nrho, thiab cov khoom siv tsis tuaj yeem ua haujlwm. You need to find a professional "road repairman" (maintenance personnel) to clean up the damaged old checkpoint and replace it with a new one of the exact same specifications.
IV. Qhov tseem ceeb Parameter (Dab tsi los saib thaum yuav khoom)
Thaum koj xav hloov lub fuse, koj tsis tuaj yeem siv ib qho xwb. Ua tib zoo saib rau cov kev txwv no:
1. Rated Tam sim no: Qhov no yog qhov tseem ceeb tshaj plaws parameter! Piv txwv li, `1A`, `2A`, `5A`. Qhov no qhia txog qhov siab tshaj plaws tam sim no nws tuaj yeem ua haujlwm ib txwm siv sijhawm ntev. Tsis txhob hloov nws nrog ib qho uas muaj zog dua tam sim no!**
2. Rated Voltage **: Piv txwv li, `32V`, `63V`, `250V`. Qhov no qhia tau hais tias qhov voltage nws tuaj yeem cuam tshuam tsis zoo ntawm lub Circuit Court.
3. Breaking Capacity **: Qhov siab tshaj plaws tam sim no lub fuse tuaj yeem cuam tshuam kev nyab xeeb. Rau cov khoom siv hluav taws xob zoo tib yam, tus qauv tawg muaj peev xwm txaus.
4.Fast Break/Slow Break:
Fast So: Tam sim ntawd melts thaum ntsib ntau dhau tam sim no, siv los tiv thaiv cov chips rhiab heev.
Slow Break: tuaj yeem tiv taus qhov luv luv tam sim no (xws li lub zog tam sim no thaum lub cav pib), thiab yuav tsis yaj tam sim ntawd; siv nyob rau hauv circuits nrog inductive Cheebtsam xws li motors.
