Hloov hom fais fab mov surge tiv thaiv txoj cai
Surge ProtectiveDevice (SurgeProtectiveDevice, SPD), tseem hu ua surge protector, yog siv los txwv qhov kev hloov pauv hloov pauv hauv lub kaw lus them nyiaj thiab coj kev tawm ntawm cov khoom siv hluav taws xob tam sim no ntawm cov khoom siv tiv thaiv tsis-linear los tiv thaiv qib qis ntawm hluav taws xob tiv thaiv hluav taws xob lossis hluav taws xob. systems los ntawm xob laim ntaus thiab xob laim electromagnetic mem tes los yog ua hauj lwm overvoltage puas. Nyob rau hauv xyoo tas los no, cov ntaub ntawv xov xwm hluav taws xob (xws li TV, xov tooj, kev sib txuas lus, khoos phis tawj, thiab lwm yam) kev loj hlob sai ntawm cov khoom siv hluav taws xob cov ntaub ntawv, muaj ntau qhov tshwm sim thiab muaj koob meej. Xws li cov tshuab thiab cov cuab yeej siv feem ntau kim dua thiab tseem ceeb, nws qhov kev khiav hauj lwm voltage, qhov hluav taws xob tiv thaiv qib qis heev, cuam tshuam rau cov teeb meem ntawm xob laim hluav taws xob mem tes, uas yuav tsum tau siv SPD los tiv thaiv overvoltage.
Raws li lub teb chaws ua raws li cov qauv sib txawv, cov khoom specifications tsis zoo ib yam, cov yam ntxwv ntawm lub logo kuj muaj lawv tus kheej lub hom phiaj, deb tsawg tshaj li lwm yam khoom siv hluav taws xob specifications, uas coj zoo inconvenience rau kev xaiv tsim. Hauv kev tsim qauv engineering, hom hom tuaj yeem muab faib ua cov khoom lag luam hauv tsev, cov khoom lag luam European thiab Asmeskas cov khoom raws li keeb kwm. Cov khoom lag luam hauv tsev parameter teeb tsa muaj kev ntxhov siab ntau dua, cov lus qhia tshwj xeeb muaj ntau yam, ntau dua qhov seem voltage. Specification ntawm cov khoom qauv teeb ib co imitation European khoom, ib co ua raws li lub teb chaws tus qauv tsis, feem ntau ntawm cov khoom yog cim nyob rau hauv thiab Imax. vim cov khoom siv hauv tsev ntawm daim ntawv thov ntawm qhov chaw qis dua, lub tsev theem tsis siab, cov khoom siv hluav taws xob muaj nuj nqis loj, yog li qee qhov kev cai yuav tsum tau ua kom haum.
Cov khoom lag luam nyob sab Europe feem ntau yog cim nrog qhov tso tawm siab tshaj plaws tam sim no, cov qauv khoom kuj tau teeb tsa raws li qhov ntsuas no. Piv txwv li, ib lub npe nrov European XXX65, XXX40, qhov twg tus nqi ntawm 65, 40 yog Imax. tab sis peb cov qauv qhia meej meej hais tias qhov nominal tso tawm tam sim no Nyob rau hauv kev xaiv, uas tam sim no ntsib nyob rau hauv engineering tsim ntawm ib tug txaj muag qhov teeb meem. Tom qab kuaj xyuas cov ntaub ntawv khoom, XX65 Hauv tus nqi tsis tshaj 20kA, XX40 Hauv tus nqi tsis tshaj 15kA. Yog tias ua raws li GB50343 tus nqi pom zoo, ob yam khoom no tsuas yog siv rau qhov kawg ntawm peb-theem kev tiv thaiv ntawm cov khoom siv, tab sis nyob rau hauv qhov tseeb tsim, tab sis ntsia nyob rau hauv thawj thiab thib ob theem, uas yog kom meej meej inconsistent. lub teb chaws tus qauv ntawm cov kev xaiv tsis, thiab qhov seem voltage yog siab tshaj qhov nruab nrab qauv feem ntau ntau tshaj 1200V, ib zaug cov xov ib puag ncig tsis zoo, nws yog ib qho yooj yim mus ua txhaum. Kev xaim ib puag ncig tsis zoo, nws yooj yim rau kev tawg ntawm cov khoom siv hluav taws xob. General European khoom Uc tus nqi yog me me, thiab speculative labeling kab voltage, yog li nyob rau hauv kev xaiv, nws yog ib qho yooj yim mus dag.
