Surge, tseem hu ua qhov hluav taws xob hloov pauv, hais txog lub sijhawm dhau los uas dhau qhov kev ua haujlwm ib txwm muaj. Qhov tseem ceeb, kev nce siab yog qhov mob siab heev uas tshwm sim hauv ob peb lab thib ob ntawm ib thib ob. Tej yam uas yuav tshwm sim muaj xws li cov khoom siv hnyav, luv luv, hloov hluav taws xob, lossis lub cav loj. Cov khoom nruab nrog surge suppression pab kiag li lawm tuaj yeem nqus tau sai sai ntawm lub zog siab, tiv thaiv cov cuab yeej txuas los ntawm kev puas tsuaj.
Ⅱ,Cov yam ntxwv ntawm Surges
Lub sijhawm ntawm qhov nce siab yog luv heev, feem ntau ntawm qhov ntsuas microsecond. Thaum muaj kev kub ntxhov tshwm sim, qhov amplitude ntawm qhov hluav taws xob thiab tam sim no tshaj ob npaug ntawm tus nqi ib txwm muaj. Vim qhov ceev ceev ntawm lub hauvmuab lim capacitor, lub ncov tam sim no ntau dua li qhov ruaj khov -lub xeev cov tswv yim tam sim no. Cov khoom siv hluav taws xob yuav tsum txwv qhov nce siab uas AC hloov pauv, txuas txuas hluav taws xob, fuses, thiab EMI lim cov khoom tuaj yeem tiv taus. Rov ua dua qhov hloov pauv yuav tsum tsis txhob ua rau lub zog hluav taws xob puas tsuaj lossis ua rau lub fuse tshuab hauv AC input voltage.
Ⅲ,Core Classification of Lightning Surge (raws li IEC 61000-4-5 International Standard)
Kev tiv thaiv theem ntawm xob laim hluav taws xob feem ntau txhais tau los ntawm qhov qhib - qhov ntsuas hluav taws xob ntsuas hluav taws xob, uas yog qhov ntsuas qhov tseem ceeb rau kev ntsuas lub peev xwm ntawm cov khoom siv hluav taws xob los tiv thaiv qhov hluav taws xob tam sim no siab - qhov hluav taws xob cuam tshuam. Cov theem tshwj xeeb thiab cov voltages sib xws yog raws li hauv qab no:

Cov xwm txheej tshwj xeeb (piv txwv li, cov cuab yeej nyob ze -voltage substations, cov khoom siv tshwj xeeb hauv huab cua daj cua dub- thaj chaw uas tuaj yeem ua tau) |
IV. General Lightning Surge Requirements rau Fais Fab Adapters
Raws li cov qauv kev lag luam (IEC 61000-4-5), kev tiv thaiv kev tiv thaiv hluav taws xob rau cov khoom siv hluav taws xob sib txawv ntawm cov xwm txheej sib txawv:
Basic Indoor Scenarios (piv txwv li, cov khoom siv hauv tsev, cov khoom siv hauv chaw ua haujlwm): Feem ntau xav tau 1.0-2.5kV kev tiv thaiv los daws cov teeb meem me me lossis cuam tshuam tsis ncaj qha.
Cov xwm txheej nrog Kev Tiv Thaiv Kev Tiv Thaiv Tus Kheej (piv txwv li, cov khoom siv hluav taws xob ua lag luam, cov khoom siv hluav taws xob sib txuas): Yuav tsum muaj kev tiv thaiv txog 6kV kom tiv thaiv tau ze - ntau yam hluav taws xob tsis ncaj los yog muaj teeb meem hauv kab sib chaws.
Cov xwm txheej tshwj xeeb heev (piv txwv li, cov chaw nres tsheb sab nraum zoov, cov khoom siv nyob ze ntawm qhov siab -voltage thaj chaw): Yuav tsum muaj kev tiv thaiv kev tiv thaiv ntawm 10kV lossis siab dua, sawv cev rau qhov siab tshaj - tus nqi xav tau tshaj qhov kev xav tau ntawm kev lag luam loj.
V. Cov txiaj ntsig zoo ntawm Topow Power Adapters: Tshaj tawm cov qauv tseem ceeb nrog tag nrho -Scenario High Protection
Shenzhen Topow Electronics Co., Ltdtshwj xeeb hauv R & D thiab tsim cov khoom siv fais fab, ua raws li cov qauv nruj nruj. Tag nrho cov khoom tau dhau los ua kev ntsuam xyuas kev ntseeg siab, suav nrog IEC / EN 61000-4-5 (surge tiv thaiv 4/6kV), tiv taus hluav taws xob, rwb thaiv tsev, thiab thermal cycling, kom ntseeg tau tias lawv muaj kev nyab xeeb thiab ruaj khov hauv ntau qhov chaw hluav taws xob.
- 4kV Kev Tiv Thaiv: Siv zog ua haujlwm sab nraum zoov thiab muaj kev lag luam siab - Ib puag ncig txaus ntshai
Piv nrog rau 2.0-2.5kV tiv thaiv txwv ntawm feem ntau cov khoom lag luam hauv kev lag luam, peb cov khoom muaj peev xwm 4kV ncaj qha ua tau raws li qhov xav tau ntawm siab-frequency high-risk scenarios xws li cov khoom siv sab nraum zoov (xws li, sab nraum zoov, chaw them nqi) thiab cov khoom siv tswj kev lag luam. Qhov no ua rau muaj txiaj ntsig zoo txo qis hluav taws xob tsis ncaj rau hauv ntau thaj tsam, txo qis qhov tsis ua haujlwm vim muaj kev puas tsuaj loj heev.
- 6kV Kev Tiv Thaiv: Txhua yam -hauv-Ib Txoj Kev Hloov "Adapter + External Surge Protector" teeb tsa
Mainstream 6kV kev tiv thaiv feem ntau tso siab rau kev sib xyaw ua ke ntawm "adapter + external surge protector (SPD)," uas ua rau cov nqi nce, teeb meem kev teeb tsa, thiab tuaj yeem txo qhov kev tiv thaiv zoo vim muaj teeb meem sib xws. Peb cov khoom ua tau zoo ua -nyob rau hauv 6kV sib xyaw ua ke tiv thaiv circuits, tshem tawm qhov xav tau ntawm cov khoom siv ntxiv. Lawv siv tau ncaj qha rau hauv cov chav lag luam neeg rau zaub mov, cov khoom siv sib txuas lus hauv network, thiab cov cuab yeej siv pej xeem hauv huab cua huab cua- thaj chaw, txuag nqi thiab txhim kho kev ntseeg tau.
- Broad Scenario Compatibility: Los ntawm Kev Lag Luam mus rau Kev Lag Luam, Tsis Xav Tau Ntau -Specification Xaiv
Feem ntau cov tuam ntxhab xav tau cov qauv sib cais rau 2.5kV (tsev neeg), 4kV (kev lag luam), thiab 6kV (kev lag luam) kev tiv thaiv, yuam cov neeg siv khoom kom muaj ntau yam kev qhia tshwj xeeb. Peb cov khoom lag luam npog 4kV-6kV tiv thaiv ntau yam, nrog rau ib qho qauv sib ntsib txhua qhov xwm txheej los ntawm kev lag luam sab nraum zoov mus rau kev lag luam siab tiv thaiv, ua kom yooj yim cov saw hlau tswj thiab txo cov khoom lag luam siab.
- Superior Stability: Sib npaug tsim rau kev tiv thaiv siab thiab tsis tshua muaj kev cuam tshuam
Qee cov khoom siv tiv thaiv siab - ntsib qhov teeb meem ntawm "kev tiv thaiv hluav taws xob ntau dua ua rau muaj kev cuam tshuam tsis tseeb nyob rau hauv ib txwm muaj," cuam tshuam kev ua haujlwm ntawm cov cuab yeej. Siv cov khoom siv surge nrhiav kom pom cov chips thiab ntau- theem kev tiv thaiv Circuit Court tsim, peb cov khoom ua tiav 4kV-6kV kev tiv thaiv siab thaum ua kom "zero misjudgment" ntawm ib txwm kab sib chaws hloov pauv, ntsuas kev tiv thaiv kev ua haujlwm thiab kev ua haujlwm ruaj khov.
