Lub zog kev koom tes txheej txheem ntawm surge tiv thaiv ntaus ntawv

Yuav kom pab tau covsurge tiv thaiv ntaus ntawvkom muaj txiaj ntsig zoo rau nws txoj haujlwm tam sim no-tso tawm thiab voltage-limiting zog, qhov hluav taws xob tam sim no tshwm sim los ntawm xob laim lossis kev ua haujlwm yuav raug qhia kom nyab xeeb rau hauv lub ntiaj teb, kom cov khoom siv hluav taws xob hluav taws xob muaj peev xwm tiv thaiv tau zoo dua, nws yog ib qho tsim nyog los ua haujlwm zoo ntawm lub zog. kev sib koom tes ntawm txhua theem ntawmsurge tiv thaiv ntaus ntawv.Cov txheej txheem tseem ceeb ntawm kev sib koom tes ntawm lub zog rausurge tiv thaiv cov cuab yeejyog:

1 Volt-ampere yam ntxwv

Raws li qhov zoo li qub volt-ampere yam ntxwv ntawm surge tiv thaiv ntaus ntawv, lub tswv yim no yog tsim rau kev koom tes ntawm voltage-txheej surge protectors.Txoj kev no tsis yog tshwj xeeb tshaj yog rau lub waveform tam sim no thiab tsis tas yuav tsum tau decoupling ntsiab.Qhov tawg impedance ntawm kab nws tus kheej muaj qee yam decoupling nyhuv.

2 Siv tshwj xeeb decoupling Cheebtsam

Nyob rau hauv thiaj li yuav tuaj txog ntawm lub hom phiaj ntawm kev koom tes, lub coupling caij nrog txaus surge kam rau ua yuav siv tau raws li lub decoupling caij (nyob rau hauv uas tus resistor yog feem ntau siv nyob rau hauv cov ntaub ntawv system thiab cov inductor feem ntau yog siv nyob rau hauv lub hwj chim system).Yog tias inductor decoupling raug xaiv, qhov steepness tam sim no yog qhov kev txiav txim siab.Qhov loj dua qhov inductance thiab tam sim no gradient, qhov yooj yim dua nws yog ua kom tiav lub zog kev koom tes.

3 Ua haujlwm nrog cov khoom siv tiv thaiv surge

Cov cuab yeej tiv thaiv kev tiv thaiv kab mob tuaj yeem siv los ua kom muaj kev sib koom tes ntawm cov khoom siv.Cov hluav taws xob hluav taws xob hluav taws xob ntawm cov khoom siv tiv thaiv hluav taws xob tiv thaiv hluav taws xob yuav tsum xyuas kom meej tias lub zog ua haujlwm siab ntawm cov khoom siv tiv thaiv kev sib koom ua ke tom ntej tsis tshaj.

Ntev npaum li qhov surge over-voltage thiab tshaj-tam sim no ntawm tag nrho cov kev txhawj xeeb, lub zog dissipated los ntawm ib qho ntawm ib qho ntawm cov kev tiv thaiv surge tsis tshaj nws txoj kev kam rau siab ua haujlwm, lub zog kev koom tes tuaj yeem ua tiav.Kev ua haujlwm tawm ntawm cov khoom siv tiv thaiv kev tiv thaiv zoo tshaj plaws yuav tsum siab dua li yav tom ntej.Cov khoom sib txuas tau raug xaiv los ua cov khoom sib txuas, thiab cov inductance tuaj yeem tawg los ntawm kev sib txuas ntawm ob-theem surge tiv thaiv cov khoom siv.Qhov voltage txwv ntawm qhov kawg thawj surge tiv thaiv ntaus ntawv yuav tsum tsawg tshaj li qhov voltage ntawm cov khoom tiv thaiv.
