Lub hauv paus ntsiab lus ntawm surge tiv thaiv rau kev hloov cov khoom siv hluav taws xob
Surge Protective Device (SPD), tseem hu ua surge protector, yog ib qho khoom siv tiv thaiv uas tsis yog siv nyob rau hauv cov tshuab nyob kom txwv tsis pub dhau lub sijhawm dhau los thiab qhia tawm cov dej ntws tawm. Nws yog siv los tiv thaiv hluav taws xob lossis hluav taws xob uas tsis muaj hluav taws xob tiv thaiv los ntawm xob laim hluav taws xob, hluav taws xob hluav taws xob los ntawm xob laim, lossis kev puas tsuaj los ntawm kev khiav hauj lwm overvoltage. Nyob rau hauv xyoo tas los no, hluav taws xob cov ntaub ntawv xov xwm (xws li TV, xov tooj, kev sib txuas lus, computer network, thiab lwm yam) tau tsim sai heev, thiab cov khoom siv hluav taws xob ntau tau tshwm sim thiab nrov. Cov hom tshuab thiab cov cuab yeej siv no feem ntau kim thiab tseem ceeb, nrog rau kev ua haujlwm tsis tshua muaj hluav taws xob thiab tiv taus cov qib voltage, thiab muaj kev cuam tshuam rau cov teeb meem ntawm xob laim electromagnetic pulses. Yog li, SPD yog xav tau rau kev tiv thaiv overvoltage.
Vim yog cov qauv sib txawv ua raws li cov teb chaws sib txawv, tsis muaj kev sib koom ua ke ntawm cov khoom tshwj xeeb, thiab kev txheeb xyuas ntawm cov tsis muaj lawv tus kheej tseem ceeb, uas yog qhov qis dua rau lwm cov khoom siv hluav taws xob tshwj xeeb, uas ua rau muaj qhov tsis yooj yim rau kev tsim thiab xaiv. Hauv kev tsim engineering, cov hom lag luam tuaj yeem muab faib ua cov khoom lag luam hauv tsev, cov khoom lag luam European, thiab cov khoom lag luam Asmeskas raws li lawv qhov chaw nyob. Cov khoom siv hauv tsev muaj chaotic parameter chaw, ntau yam specifications, thiab siab residual siab. Cov qauv tsim qauv tsim qauv suav nrog qee cov khoom lag luam nyob sab Europe, thaum lwm tus ua raws li cov qauv hauv tebchaws. Cov khoom lag luam feem ntau yog sau nrog In thiab Imax. Vim tias qhov kev xav tau ntawm cov khoom siv hauv tsev tsis tshua muaj rau thaj chaw thov, qib tsev qis, thiab cov cuab yeej siv hluav taws xob siab, qee qhov kev xav tau tuaj yeem ua kom haum.
Cov khoom lag luam nyob sab Europe feem ntau sau nrog qhov siab tshaj plaws tawm tam sim no, thiab cov qauv khoom kuj tau teeb tsa raws li qhov ntsuas no. Piv txwv li, lub npe nrov European hom XXX65 thiab XXX40, qhov twg qhov tseem ceeb ntawm 65 thiab 40 yog Imax. Txawm li cas los xij, tus qauv hauv peb lub teb chaws tau hais meej meej tias qhov nominal paug tam sim no nyob rau hauv yuav tsum tau siv rau kev xaiv, uas tam sim no yog qhov teeb meem tsis txaus ntseeg tau ntsib hauv engineering tsim. Tom qab kuaj xyuas cov ntaub ntawv ntawm cov khoom, tus nqi ntawm XX65 tsis tshaj 20kA, thiab hauv tus nqi ntawm XX40 tsis tshaj 15kA. Yog tias cov txiaj ntsig tau pom zoo ntawm GB50343 tau ua raws, ob yam khoom no tsuas yog siv tau rau kev tiv thaiv peb theem tom kawg ntawm cov khoom siv. Txawm li cas los xij, hauv kev tsim qauv tiag tiag, lawv tau teeb tsa rau qib thawj thiab qib thib ob, uas yog qhov pom tseeb tsis sib haum nrog cov kev xaiv ntawm lub teb chaws tus qauv, thiab qhov seem hluav taws xob yog qhov siab. Cov qauv qub feem ntau tshaj 1200V. Thaum qhov chaw xaim tsis zoo, nws yog ib qho yooj yim kom dhau cov khoom siv tiv thaiv tus nqi hluav taws xob. Feem ntau, cov khoom lag luam nyob sab Europe muaj tus nqi Uc me dua thiab muaj lub sijhawm zoo rau kev sau cov kab hluav taws xob, ua rau nws yooj yim rau kev dag ntxias thaum xaiv.
