Vim li cas lub Surge Protector Device hlawv tawm?

Covsurge tiv thaivyog ib qho khoom siv tseem ceeb rau kev tiv thaiv overvoltage cuam tshuam ntawm cov khoom siv hluav taws xob hauv tsev.Raws li kev tiv thaiv ntawm SPD, txawm hais tias xob laim txog li kaum ntawm kiloamps invas lub sab hauv Circuit Court, lub surge protector tuaj yeem tawm sai sai rau hauv daim phiaj hauv av, los tiv thaiv kev ruaj ntseg thiab kev nyab xeeb ntawm peb cov khoom siv hluav taws xob.Txawm li cas los xij, nyob rau xyoo tas los no, qhov teeb meem hluav taws kub ntawm cov khoom tiv thaiv hluav taws xob tau tshwm sim los ntawm lub sijhawm.Txawm hais tias lub surge protector muaj kev nyab xeeb los yog tsis thiab vim li cas lub surge protector kub hnyiab tau dhau los ua kev txhawj xeeb rau cov neeg siv.Niaj hnub no, peb yuav muab ib tug nrov science rau koj vim li cas lub surge protector hlawv tawm.

xob laim tam sim no, feem ntau muaj cov tam sim no siab, ceev ceev cov yam ntxwv, feem ntau nyob rau hauv kaum ob los yog pua pua ntawm microseconds yuav dhau kaum ntawm kiloamperes ntawm lub siab tam sim no, yog tsis tso tawm, yuav ua rau tuag taus rau kev siv cov khoom siv hluav taws xob thiab tib neeg lub neej.Surge tiv thaiv siv lub siab-rhiab heev resistors los yog tawm qhov khoob, nyob rau hauv ib txwm ua hauj lwm yog sib npaug rau ib tug kuj zoo kawg thiab tsis cuam tshuam rau ib txwm ua hauj lwm ntawm lwm yam khoom siv hluav taws xob, nyob rau hauv lub xob laim tam sim no intrusion kab sai sai, xob laim tam sim no luv luv-circuit rau ceg. thiab tso tawm rau cov khoom siv hauv av.Lub xeev SPD tshwm sim los ntawm cov hluav taws xob muaj zog ncaj qha feem ntau yog tawg, thiab tsis muaj sijhawm rau SPD hlawv.Yog li vim li cas lub surge protector ntaus ntawv hlawv tawm?

Cov cuab yeej tiv thaiv hluav taws xob tau siv rau ntawm txoj kab ntev ntev, thiab nws yuav maj mam deteriorate.Lub sijhawm no, thaum cov khoom siv loj ntawm kab pib ua haujlwm, kev khiav hauj lwm overvoltage yuav raug tsim.Qhov kev khiav hauj lwm overvoltage no yuav ua rau lub varistor tsim luv-circuit tam sim no.Raws li cov qauv hluav taws xob hluav taws xob tsim hluav taws xob, thaum lub tshav kub mus txog ib theem, tus tiv thaiv hluav taws xob yuav ua kom muaj cua sov ntau thiab ua rau hluav taws kub hnyiab.Yog li ntawd, lub surge protector yog hlawv tawm, feem ntau tshwm sim los ntawm luv luv-circuit tam sim no.

Vim li no, nws tau hais meej meej nyob rau hauv GB 51348-2019 tias lub hauv ntej kawg ntawm tus tiv thaiv surge yuav tsum tau nruab nrog tshwj xeeb SPD backup tiv thaiv.Thaum lub caij luv luv tam sim no tshwm sim nyob rau hauv txoj kab, lub surge backup protector yog sai sai disconnected, yog li ntawd lub surge protector tiv thaiv, li no lub surge protector yuav tsis hlawv tawm.
