SPD rau Cov Lus Qhia Xaiv Cov Koob Tshuaj Fais Fab

Kev teeb tsa SPD ntawm txhua thaj chaw tiv thaiv xob laim, raws li tus qauv ntawm qhov pom hluav taws xob qis, ua rau kev faib tawm ntawm cov khoom siv hluav taws xob raws li qeb dhau voltage, nws cov rwb thaiv tsev tiv taus impulse voltage theem tuaj yeem txiav txim siab xaiv SPD. Raws li tus qauv ntawm qhov pom hluav taws xob qis, ua rau kev faib tawm ntawm cov khoom siv hluav taws xob raws li qeb dhau voltage raws li qib teeb liab, qib thauj khoom, qib faib thiab tswj, qib muab hluav taws xob. Nws cov rwb thaiv tsev tiv taus impulse voltage theem yog: 1500V, 2500V, 4000V, 6000V. Raws li qhov chaw teeb tsa khoom siv tiv thaiv sib txawv thiab qhov sib txawv xob laim tam sim no ntawm thaj chaw tiv thaiv xob laim sib txawv, txhawm rau txiav txim siab qhov chaw teeb tsa ntawm SPD rau kev muab hluav taws xob thiab lub peev xwm tawg.

Qhov kev ncua deb ntawm txhua theem SPD yuav tsum tsis pub tshaj 10m, qhov kev ncua deb ntawm SPD thiab cov khoom siv tiv thaiv yuav tsum luv li sai tau, tsis pub tshaj 10m. Yog tias vim muaj kev txwv ntawm qhov chaw teeb tsa, tsis tuaj yeem lav qhov kev ncua deb ntawm kev teeb tsa, ces yuav tsum tau teeb tsa cov khoom sib cais ntawm txhua theem SPD, ua kom SPD tom qab chav kawm raug tiv thaiv los ntawm chav kawm SPD ua ntej. Hauv lub kaw lus fais fab tsawg voltage, kev txuas lub inductor tuaj yeem ua tiav lub hom phiaj sib cais.

SPD rau cov ntsiab cai xaiv cov khoom siv hluav taws xob

Qhov siab tshaj plaws ntawm lub zog ua haujlwm tas mus li: loj dua li cov khoom siv tiv thaiv, qhov siab tshaj plaws ntawm lub zog ua haujlwm tas mus li ntawm lub kaw lus.

TT System: Uc≥1.55Uo (Uo yog qhov system qis voltage rau null kab voltage)

TN System: Uc≥1.15Uo

IT System: Uc≥1.15Uo (Uo yog qhov system qis voltage rau kab voltage)

Qib Kev Tiv Thaiv Voltage: tsawg dua qhov rwb thaiv tsev withstand impulse voltage ntawm cov khoom siv tiv thaiv

Qhov ntsuas hluav taws xob tam sim no: txiav txim siab raws li qhov xwm txheej xob laim ntawm qhov chaw teeb tsa thiab thaj chaw tiv thaiv xob laim.
