    Surge Protection Device (1)

     

    Dab tsi yog Surge Protective Device (SPD)?

    Surge Protective Device (SPD) yog ib feem ntawm kev tiv thaiv hluav taws xob.Cov cuab yeej no txuas rau tib lub sijhawm rau lub zog hluav taws xob ntawm cov khoom thauj uas nws yuav tsum tau tiv thaiv.Cov cuab yeej tiv thaiv surge redirects hluav taws xob tam sim no zoo li nominal tawm tam sim no los ntawm luv luv Circuit Court.Nws ua li ntawd yog siv ib qho kev sib cuag nrog lub xeev lossis qhov hloov pauv huab cua.Tsis tas li ntawd, cov cuab yeej tiv thaiv surge ua hauj lwm ua ib qho kev ruaj ntseg shutoff ntaus ntawv rau overcurrent tej yam kev mob thiab ib tug recloser uas tswj lub voltage theem saum toj no lub rated voltage los yog tsawg voltage nyob rau hauv cov kev tshwm sim ntawm ib tug txhaum.Peb kuj tuaj yeem siv cov cuab yeej tiv thaiv surge ntawm txhua theem ntawm cov khoom siv hluav taws xob.Txoj kev no feem ntau yog qhov tseem ceeb tshaj plaws uas siv thiab ua tau zoo tshaj plaws ntawm kev tiv thaiv overvoltage.

    Surge tiv thaiv ntaus ntawv txuas nrog nyob rau hauv parallel nta ib tug siab impedance.Nyob rau hauv lwm yam lus, cov sum ntawm series impedance yog sib npaug zos rau impedance ntawm ib tug surge tiv thaiv ntaus ntawv.Thaum lub sij hawm overvoltage tshwm nyob rau hauv lub system, lub ntaus ntawv impedance txo, yog li surge tam sim no yog tsav los ntawm lub surge tiv thaiv ntaus ntawv, bypassing cov khoom rhiab heev.Qhov ntawd yog los tiv thaiv cov cuab yeej tiv thaiv overvoltage transients thiab cuam tshuam, xws li voltage spikes thiab hluav taws xob surges, zaus variations, thiab over-voltages tshwm sim los ntawm switching hauj lwm los yog xob laim.Thaum tus neeg siv nruab ib lub surge strip los yog ib tug surge tiv thaiv ntaus ntawv mus rau hauv ib lub hwj chim kab los ntawm lub hwj chim utility uas muaj xws li smoothing capacitors, surge suppressors tsis tsim nyog vim hais tias cov capacitors twb tiv thaiv los ntawm tam sim ntawd hloov nyob rau hauv voltage theem.
