Tus tiv thaiv hluav taws xobKev tiv thaiv tseem ceeb rau cov khoom siv hluav taws xob
Hauv lub ntiaj teb digital uas nce zuj zus, tib neeg vam khom cov khoom siv hluav taws xob ntau dua li yav dhau los. Txij li cov xov tooj ntse thiab cov laptops mus rau cov khoom siv hauv tsev thiab cov tshuab ua haujlwm, cov khoom siv no tau dhau los ua ib feem tseem ceeb ntawm peb lub neej txhua hnub. Txawm li cas los xij, qhov kev vam khom no kuj coj kev pheej hmoo ntawm kev nce hluav taws xob, uas tuaj yeem ua rau muaj kev puas tsuaj loj rau peb cov khoom siv hluav taws xob. Qhov no yog thaum cov khoom siv tiv thaiv kev nce hluav taws xob (SPDs) tseem ceeb heev.
Cov khoom siv tiv thaiv hluav taws xob ntau dhau (surge protectors) yog tsim 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 los ntawm ntau yam, suav nrog xob laim, hluav taws xob tsis ua haujlwm, thiab txawm tias kev ua haujlwm ntawm cov khoom siv loj uas siv hluav taws xob ntau. Thaum muaj kev nce siab, nws tuaj yeem ua rau lub cuab yeej hluav taws xob ntawm lub cuab yeej puas tsuaj, ua rau nws ua haujlwm tsis zoo lossis txawm tias ua tsis tiav kiag li. SPDs ua haujlwm zoo li ib qho thaiv, hloov cov hluav taws xob ntau dhau ntawm cov khoom siv rhiab heev, ua rau nws muaj kev nyab xeeb.
Qhov tseem ceeb ntawm kev tiv thaiv hluav taws xob tsis tuaj yeem hais dhau lawm. Raws li National Fire Protection Association (NFPA), kev nce hluav taws xob ua rau muaj ntau txhiab qhov hluav taws thiab ntau lab daus las hauv kev puas tsuaj rau khoom vaj khoom tsev txhua xyoo. Los ntawm kev nqis peev rau hauv cov khoom tiv thaiv hluav taws xob zoo, cov tib neeg thiab cov lag luam tuaj yeem tiv thaiv lawv cov peev txheej thiab zam kev kho lossis hloov pauv kim.
Muaj ntau hom khoom siv tiv thaiv hluav taws xob (SPDs) muaj nyob rau hauv kev ua lag luam, txhua yam muaj lub hom phiaj tshwj xeeb. Cov khoom siv tiv thaiv hluav taws xob ntsaws yog cov khoom siv feem ntau hauv cov khoom siv hluav taws xob hauv tsev. Cov khoom siv no zoo ib yam li cov hlua hluav taws xob, tab sis muaj kev tiv thaiv hluav taws xob ua ke. Lawv zoo tagnrho rau kev tiv thaiv cov khoom siv hluav taws xob tus kheej xws li khoos phis tawj, TV, thiab cov khoom ua si. Yog xav tau kev tiv thaiv dav dua, cov khoom siv tiv thaiv hluav taws xob thoob plaws hauv tsev tuaj yeem ntsia tau ntawm lub rooj tsavxwm faib khoom. Cov khoom siv no yog thawj kab tiv thaiv tiv thaiv hluav taws xob uas nkag mus rau hauv lub tsev lub cev hluav taws xob.
Hauv kev lag luam thiab kev lag luam, qhov xav tau kev tiv thaiv hluav taws xob ntau ntxiv yog qhov tseem ceeb dua. Cov lag luam feem ntau vam khom cov khoom siv kim thiab cov tshuab uas tuaj yeem cuam tshuam loj heev los ntawm kev nce hluav taws xob. Cov khoom siv tiv thaiv hluav taws xob ntau hauv kev lag luam (SPDs) tau tsim los tswj cov qib hluav taws xob siab dua thiab tuaj yeem tiv thaiv tag nrho lub kaw lus, kom ntseeg tau tias kev ua haujlwm tsis cuam tshuam thiab cov khoom siv tseem ua haujlwm tau.
Thaum xaiv lub tshuab tiv thaiv hluav taws xob ntau dhau, yuav tsum xav txog ntau yam. Lub zog clamping ntawm lub cuab yeej, lub sijhawm teb, thiab lub peev xwm nqus hluav taws xob yog cov yam tseem ceeb uas txiav txim siab nws qhov ua tau zoo. Lub zog clamping yog hais txog qib voltage uas lub tshuab tiv thaiv hluav taws xob ntau dhau (SPD) pib hloov pauv overvoltage. Lub zog clamping qis dua, qhov kev tiv thaiv zoo dua rau cov khoom siv rhiab heev. Lub sijhawm teb qhia tias lub cuab yeej teb sai npaum li cas rau lub zog surge, thiab lub sijhawm teb sai dua, qhov kev tiv thaiv zoo dua. Lub peev xwm nqus hluav taws xob ntsuas qhov ntau ntawm lub zog uas lub cuab yeej tuaj yeem nqus tau ua ntej ua tsis tiav, yog li nws yog ib qho tseem ceeb rau cov chaw muaj zog siab.
Ntxiv rau kev tiv thaiv cov khoom siv, SPDs ua rau lub neej ntawm cov khoom siv hluav taws xob ntev dua. Los ntawm kev tiv thaiv kev puas tsuaj los ntawm kev nce hluav taws xob, cov khoom siv no pab tswj cov khoom siv ua haujlwm thiab kev ntseeg siab rau lub sijhawm ntev. Qhov no tseem ceeb heev rau cov lag luam uas vam khom thev naus laus zis los ua haujlwm, vim tias lub sijhawm tsis ua haujlwm tuaj yeem ua rau poob nyiaj tau los thiab kev tsim khoom.
Txhua yam hais los saum toj no, lub cuab yeej tiv thaiv hluav taws xob yog qhov tseem ceeb rau txhua tus neeg uas siv cov khoom siv hluav taws xob. Txawm nyob hauv tsev lossis chaw ua lag luam, kev tiv thaiv hluav taws xob tiv thaiv yog qhov tseem ceeb rau kev tswj hwm kev ua haujlwm thiab lub neej ntawm koj cov khoom siv. Muaj ntau yam cuab yeej tiv thaiv hluav taws xob muaj nyob rau hauv kev ua lag luam, thiab nws yog ib qho tseem ceeb uas yuav tsum xaiv ib qho uas ua tau raws li koj cov kev xav tau tshwj xeeb. Ua li no, koj tuaj yeem ua kom ntseeg tau tias koj cov khoom siv hluav taws xob ua haujlwm zoo thiab ruaj khov, ua rau koj muaj kev thaj yeeb nyab xeeb hauv lub ntiaj teb hluav taws xob no.
