    SPD rau Cov Khoom Siv Hluav Taws Xob Series Series Xaiv Phau Ntawv Qhia

    Kev teeb tsa ntawm SPD ntawm txhua cheeb tsam tiv thaiv xob laim, raws li tus qauv ntawm cov hluav taws xob tsis tshua muaj hluav taws xob zoo li, ua kom muaj kev faib tawm ntawm cov khoom siv hluav taws xob raws li cov khoom siv hluav taws xob dhau, nws cov rwb thaiv tsev tiv thaiv impulse voltage theem tuaj yeem txiav txim siab xaiv SPD.Raws li tus qauv ntawm cov hluav taws xob tsis tshua muaj hluav taws xob zoo li qub, ua kom muaj kev faib tawm ntawm cov khoom siv hluav taws xob raws li cov khoom siv hluav taws xob ntau dhau raws li cov teeb liab theem, theem kev thauj khoom, kev faib tawm thiab kev tswj hwm qib, qib khoom siv hluav taws xob.Nws cov rwb thaiv tsev tiv thaiv impulse voltage yog: 1500V, 2500V, 4000V, 6000V.Raws li kev tiv thaiv cov cuab yeej teeb tsa txoj haujlwm sib txawv thiab qhov sib txawv xob laim tam sim no ntawm qhov sib txawv ntawm kev tiv thaiv hluav taws xob, txhawm rau txiav txim siab qhov chaw teeb tsa ntawm SPD rau cov khoom siv hluav taws xob thiab lub peev xwm tawg.
    Qhov kev ncua deb ntawm txhua theem SPD yuav tsum tsis txhob ntau tshaj 10m, qhov kev ncua deb ntawm SPD thiab cov khoom tiv thaiv yuav tsum luv li sai tau, tsis ntau tshaj 10m.Yog tias vim muaj kev txwv ntawm txoj haujlwm kev teeb tsa, tsis tuaj yeem lav qhov kev ncua deb, ces yuav tsum tau nruab decoupling tivthaiv ntawm txhua qib SPD, ua rau tom qab chav kawm SPD tiv thaiv los ntawm chav kawm ua ntej SPD.Hauv qhov hluav taws xob qis hluav taws xob, kev sib txuas ntawm inductor tuaj yeem ua tiav lub hom phiaj decoupling.
    SPD rau fais fab mov system specification xaiv txoj cai
    Max.kev khiav hauj lwm tsis tu ncua voltage: loj dua cov khoom tiv thaiv, lub kaw lus max.tsis tu ncua kev khiav hauj lwm voltage.
    TT System: Uc≥1.55Uo (Uo yog qhov tsis tshua muaj hluav taws xob rau cov kab hluav taws xob tsis zoo)
    TN System: Uc≥1.15Uo
    IT System: Uc≥1.15Uo (Uo yog qhov hluav taws xob qis rau kab hluav taws xob)
    Voltage Protection Level: tsawg dua cov rwb thaiv tsev tiv thaiv impulse voltage ntawm cov khoom tiv thaiv
    Rated tso tawm tam sim no: txiav txim siab raws li qhov xwm txheej xob laim ntawm txoj haujlwm teeb tsa thiab kev tiv thaiv hluav taws xob.
