Kev Nkag SiabCov Khoom Tiv Thaiv SurgeKev Nyab Xeeb Hluav Taws Xob Tseem Ceeb
Nyob rau hauv lub ntiaj teb digital uas nce zuj zus, cov khoom siv hluav taws xob tau dhau los ua ib feem tseem ceeb ntawm peb lub neej txhua hnub, thiab qhov tseem ceeb ntawm kev tiv thaiv cov khoom siv no tsis tuaj yeem hais ntau dhau. Ib txoj hauv kev zoo tshaj plaws los tiv thaiv cov khoom siv hluav taws xob yog siv lub tshuab tiv thaiv hluav taws xob. Tsab xov xwm no yuav saib ze dua txog cov tshuab tiv thaiv hluav taws xob yog dab tsi, lawv ua haujlwm li cas, thiab vim li cas lawv thiaj tseem ceeb hauv tsev thiab chaw ua haujlwm.
Lub tshuab tiv thaiv hluav taws xob yog dab tsi?
Lub tshuab tiv thaiv hluav taws xob (surge protector) yog ib lub cuab yeej siv los tiv thaiv cov khoom siv hluav taws xob ntawm qhov hluav taws xob nce siab. Cov kev nce siab no tuaj yeem tshwm sim rau ntau yam, suav nrog xob laim, hluav taws xob tsis ua haujlwm, thiab txawm tias cov khoom siv loj pib ua haujlwm sai sai. Thaum qhov hluav taws xob siab tshaj qhov txwv, lub tshuab tiv thaiv hluav taws xob yuav hloov qhov hluav taws xob siab dhau ntawm cov khoom siv txuas nrog, tiv thaiv kev puas tsuaj.
Lub tshuab tiv thaiv kev kub ntxhov ua haujlwm li cas?
Cov khoom tiv thaiv hluav taws xob ntau dhau siv ib qho khoom hu ua hlau oxide varistor (MOV). MOV yog ib qho semiconductor uas nws qhov kev tiv thaiv hloov pauv nyob ntawm qib voltage. Hauv qab cov xwm txheej ib txwm muaj, MOV tso cai rau tam sim no ntws mus rau koj cov khoom siv. Txawm li cas los xij, thaum muaj hluav taws xob ntau dhau, MOV ntes tau qhov overvoltage thiab xa nws mus rau hauv av, tiv thaiv koj cov khoom siv kom tsis txhob puas tsuaj.
Feem ntau cov khoom tiv thaiv hluav taws xob kuj muaj lwm yam ntxwv, xws li cov cuab yeej txiav hluav taws xob (uas txiav hluav taws xob thaum muaj hluav taws xob ntau heev) thiab cov teeb qhia (uas qhia seb lub cuab yeej puas ua haujlwm zoo). Qee cov qauv siab heev txawm tias muaj cov yam ntxwv xws li cov chaw nres nkoj USB rau them cov khoom siv mobile thiab cov Wi-Fi routers uas ua rau hauv.
Vim li cas cov khoom tiv thaiv hluav taws xob thiaj tseem ceeb?
1. Tiv thaiv kom tsis txhob muaj hluav taws xob ntau dhau: Lub luag haujlwm tseem ceeb ntawm lub cuab yeej tiv thaiv hluav taws xob ntau dhau yog tiv thaiv koj cov khoom siv hluav taws xob kom tsis txhob muaj hluav taws xob ntau dhau. Yog tsis muaj qhov kev tiv thaiv no, cov khoom siv xws li khoos phis tawj, TV, thiab cov khoom siv hauv tsev tuaj yeem raug kev puas tsuaj uas tsis tuaj yeem kho tau, ua rau muaj kev kho lossis hloov pauv kim heev.
2. Kev daws teeb meem uas pheej yig: Kev nqis peev rau hauv lub tshuab tiv thaiv hluav taws xob yog ib txoj hauv kev pheej yig los tiv thaiv koj cov khoom siv hluav taws xob muaj nqis. Tus nqi ntawm lub tshuab tiv thaiv hluav taws xob tsis tseem ceeb piv rau tus nqi ntawm kev hloov lub cuab yeej puas tsuaj.
3. Kev Thaj Yeeb ntawm Lub Siab: Kev paub tias koj cov khoom siv tau tiv thaiv los ntawm kev nce hluav taws xob tsis tau xav txog tuaj yeem ua rau koj muaj kev thaj yeeb ntawm lub siab. Qhov no tseem ceeb heev rau cov neeg uas vam khom cov khoom siv hluav taws xob rau kev ua haujlwm lossis kev siv tus kheej.
4. Ua kom koj cov khoom siv siv tau ntev dua: Los ntawm kev tiv thaiv cov hluav taws xob nce siab, cov khoom tiv thaiv hluav taws xob tuaj yeem pab ua kom koj cov khoom siv hluav taws xob siv tau ntev dua. Qhov no txhais tau tias koj tuaj yeem siv koj cov khoom siv tau ntev dua yam tsis txhawj txog kev puas tsuaj ua ntej lub sijhawm.
Xaiv Lub Tshuab Tiv Thaiv Surge Zoo
Thaum xaiv lub tshuab tiv thaiv hluav taws xob, xav txog cov hauv qab no:
- Kev Ntsuas Joule: Qhov kev ntsuas no qhia tau tias lub zog tiv thaiv hluav taws xob tuaj yeem nqus tau ntau npaum li cas ua ntej ua haujlwm tsis ua haujlwm. Qhov kev ntsuas joule siab dua, qhov kev tiv thaiv zoo dua.
- Tus naj npawb ntawm cov qhov hluav taws xob: Xyuas kom tseeb tias lub cuab yeej tiv thaiv hluav taws xob muaj cov qhov hluav taws xob txaus rau tag nrho koj cov khoom siv. Qee cov qauv kuj muaj cov qhov hluav taws xob sib nrug kom haum rau cov ntsaws loj dua.
- Lub Sijhawm Teb: Nrhiav ib lub cuab yeej tiv thaiv hluav taws xob uas muaj lub sijhawm teb sai kom ntseeg tau tias muaj kev tiv thaiv tam sim ntawd thaum muaj hluav taws xob ntau dhau.
