Lub tswv yim ntawm hluav taws xob thaiv cheeb tsam
Lub laj kab hluav taws xob tiv thaiv lub ntsiab lus tso cai rau los npaj, siv thiab ntsuas kev tiv thaiv. 
Txhua yam khoom siv sib txuas, kev teeb tsa, thiab cov tshuab yuav tsum muaj kev tiv thaiv zoo rau kev lag luam tsim nyog. Txog qhov kawg no, lub tsev faib rau hauv cov cheeb tsam nrog cov kev pheej hmoo txawv. Raws li cov aav no, cov kev tiv thaiv xav tau tuaj yeem txiav txim siab, tshwj xeeb, cov hluav taws xob thiab cov nplai tiv thaiv cov khoom siv thiab cov khoom siv.
EMC-based (EMC = electromagnetic compatibility) lub teeb tsa hluav taws xob tiv thaiv lub tswv yim suav nrog kev tiv thaiv sab nraud teeb pom kev zoo (huab cua-tshuab kaw lus, qis tus neeg xyuas pib, pob ntseg), kev sib koom ua ke, kev sib tiv thaiv sib tiv thaiv thiab tiv thaiv kom zoo rau lub zog hluav taws xob thiab cov ntaub ntawv thev naus laus zis system. Cov chaw tiv thaiv xob laim yog txhais raws hauv qab no.
Xob thaiv cov cheeb tsam thiab cov ntsuas kev tiv thaiv zoo
Cov cuab yeej tiv thaiv zoo tau muab cais ua cov xob laim tam sim no cov neeg raug ntes, cov neeg raug ntes, thiab cov neeg ntes sib txuas ua ke raws li qhov yuav tsum tau ua ntawm lawv qhov chaw teeb tsa. Xob laim tam sim no thiab cov tub ceev xwm ntes uas tau ntsia ntawm qhov kev hloov ntawm LPZ 0A rau 1 / LPZ 0A kom 2 ua tiav qhov kev nruj tshaj plaws raws li qhov muaj peev xwm tawm. Cov neeg raug ntes no yuav tsum muaj peev xwm tawm ntawm cov hluav taws xob ib nrab ntawm 10/350 waves yoj ob peb zaug uas tsis muaj kev rhuav tshem, yog li tiv thaiv kev txhaj tshuaj ntawm kev cuam tshuam ib feem ntawm xob laim tam sim no mus rau kev teeb tsa hluav taws xob ntawm lub tsev.
Cov neeg ntes cov neeg raug ntes tau raug nruab ntawm kev hloov los ntawm LPZ 0B rau 1 thiab nqes dej ntawm lub teeb hluav taws xob ntes tam sim no ntawm kev hloov los ntawm LPZ 1 rau 2 thiab siab dua. Lawv txoj haujlwm yog los ua kom tsis tshua muaj qhov seem ntawm cov theem pov thaiv kev tiv thaiv ib puag ncig thiab kom muaj kev txwv qhov tsis txaus siab hauv kev teeb tsa lossis kev tsim tawm hauv lub teeb.
Cov lus piav qhia txog kev tiv thaiv xob laim thiab ntsuas kev tiv thaiv ntawm thaj tsam ntawm cov chaw tiv thaiv xob laim yuav tsum tau siv ob qho tib si rau kev tso fais fab thiab cov ntaub ntawv siv thev naus laus zis. Cov kev siv tas li ntawm cov kev ntsuas piav qhia ua kom ntseeg tau tas mus li ntawm cov txheej txheem niaj hnub no.
Kev txhais cov ntsiab lus ntawm qhov chaw thaiv hluav taws xob
LEMP kev tiv thaiv ntawm cov qauv vaj tse nrog hluav taws xob thiab hluav taws xob nyob rau hauv raws li IEC 62305-4
ZPO 0A Thaj chaw uas qhov kev hem thawj yog vim muaj qhov tso hluav taws xob ncaj ncaj thiab lub teeb hluav taws xob puv hluav taws xob. Lub kaw lus sab hauv yuav raug rau ntawm kev ua haujlwm pabcuam tamsim no.
ZPO 0B Thaj chaw tiv thaiv tawm tsam ncaj qha xob laim tab sis qhov chaw hem yuav muaj hluav taws xob puv hluav taws xob. Lub kaw lus sab hauv yuav raug rau cov hluav taws xob qee qhov ntawm tam sim no.
ZPO 1 Thaj chaw uas qhov chaw phais tam sim no tau txwv los ntawm kev sib qhia tam sim no thiab los ntawm SPDs ntawm tus ciam. Kev thaiv cov xov hauv kev sib tsoo tej zaum yuav attenuate xob laim electromagnetic teb.
ZPO 2 Thaj chaw uas qhov chaw phais tam sim no yuav raug txwv ntxiv ntxiv los ntawm kev sib qhia tam sim no thiab los ntawm SPD ntxiv ntawm cov ciam teb. Kev siv cov xov thaiv ntxiv yuav raug coj los txuas ntxiv rau lub ntsej muag hluav taws xob hluav taws xob.
