Yuav ua li cas xaiv tus tiv thaiv surge - tsis txhob quav ntsej qhov no!

Yog tias cov ntaub ntawv muaj txiaj ntsig zoo siv hluav taws xob cov khoom siv hluav taws xob hauv lub tsev, lawv lub peev xwm los tiv thaiv cov hluav taws xob hluav taws xob tsawg dua li cov khoom siv hluav taws xob yooj yim, nws yog ib qho tsim nyog yuav tau siv cov khoom siv hluav taws xob.surge tiv thaivkom tswj tau cov khoom siv hluav taws xob zoo li no, tom qab ntawd yuav ua li cas thiaj xaiv cov surge Ua li cas txog cov khoom tiv thaiv?
Ua ntej xaiv asurge tiv thaiv, yuav tsum tau ua raws li kev soj ntsuam kev pheej hmoo ntawm xob laim thiab coj mus rau hauv tus account kev lag luam ntawm qhov project, tsis yog tsuas yog kev puas tsuaj ncaj qha, tab sis kuj muaj kev puas tsuaj ncaj qha (rau cov ntaub ntawv kev tswj hwm, kev puas tsuaj tsis ncaj feem ntau yog siab dua li ntxiv rau cov kev cai thiab cov kev cai. hnub no xav tau lub installation ntawmsurge tiv thaiv, xws li cov qauv kev lag luam hauv teb chaws xws li GB 50057. Hauv qab no, kuv yuav piav qhia yuav ua li cas xaiv tus tiv thaiv surge los ntawm ntau qib.

Txhawm rau kom ntseeg tau tias cov khoom siv hluav taws xob tsis yooj yim thiab cov ntaub ntawv xov xwm yuav tsis raug teeb meem los ntawm kev cuam tshuam ntawm xob laim thiab surges, IEC 62305 kom meej meej txhais cov ntsiab lus ntawm kev tiv thaiv hluav taws xob.

LPZ 0A: raug rau xob laim tawm ncaj qha, coj txhua qhov xob laim thiab tag nrho cov hluav taws xob hluav taws xob.

LPZ 0B: Kev tiv thaiv hluav taws xob ncaj qha, tiv thaiv qee qhov hluav taws xob tam sim no lossis cuam tshuam tam sim no, thiab tag nrho cov hluav taws xob sib nqus.

LPZ 1: Kev tiv thaiv hluav taws xob ncaj qha, hluav taws xob hauv zos lossis cov dej ntws tawm, thiab cov hluav taws xob sib nqus sib nqus.Lub surge yog txwv rau shunted ntawm ciam teb thiab tiv thaiv los ntawm ib tug surge protector, thiab electromagnetic teb muaj spatial shielded attenuation.

LPZ 2…n: Zoo ib yam li LPZ 1, tab sis nrog ntxiv attenuation ntawm electromagnetic teb rau xob laim.Raws li txoj cai kev tiv thaiv dav dav, cov khoom tiv thaiv yuav tsum tau muab tso rau hauv thaj tsam LPZ uas nws cov khoom siv hluav taws xob sib haum nrog lub peev xwm los tiv thaiv kev puas tsuaj los txo kev puas tsuaj (lub cev puas tsuaj, tsis ua haujlwm ntawm hluav taws xob thiab hluav taws xob vim yog overvoltage, thiab lwm yam.微信图片_20220427140412

Yuav ua li cas xaiv tus cojsurge tiv thaiv

Thaum nws tsis tuaj yeem ntsuas cov chav kawm 1 surge protector (Type1, Class1), Iimp≥12.5kA feem ntau siv, uas yog hais tias, 12.5kA yog txaus nyob rau hauv feem ntau.Peb pom zoo kom siv Iimp = 25kA, thiaj li yuav muaj lub peev xwm loj dua, lub neej ua haujlwm ntev dua.

Rau cov chav kawm 2 surge protectors (Type2, Class2), peb xaiv siv 20/40kA (In = 20kA, Imax = 40kA) fais fab surge protectors, thiab xob laim tawm tsam saum 40kA (tom qab LPZ1) tsis tshua muaj tshwm sim hauv cov ntawv thov tshwj xeeb.ntawm.Muaj ntau hom Class 2 surge protectors, xws li 40/80kA, 50/100kA, thiab 60/120kA power surge protectors.

Ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb hauv peb lub xeev ua haujlwm

1. Lub xeev tos: voltage aging yam ntxwv, av noo thiab tshav kub kuj yam ntxwv, muaj kev ruaj ntseg nqa tam sim no ntawm dual-chaw nres nkoj surge protector;

2. Surge suppression teeb meem: Ntxiv nrog rau lub zog ntawm lub zog ua haujlwm voltage, lub surge protector kuj muaj lub zog los ntawm qhov surge voltage;

3. TOV kev khiav hauj lwm lub xeev: cov hluav taws xob kev nyuaj siab ntawm lubsurge tiv thaivFeem ntau yog TOV ua haujlwm voltage thiab tam sim no.Qhov no muaj feem xyuam rau daim phiaj zoo, tsis tshua muaj hluav taws xob hluav taws xob thiab kev faib tshuab, nruab nrab qhov hluav taws xob faib tshuab thiab cov txheej txheem hauv av rau kev faib hluav taws xob.Qhov no yuav tsum tau muaj yog lub peev xwm ntawm tus tiv thaiv surge tiv thaiv overvoltages ib ntus, uas yog, tus tiv thaiv hluav taws xob tuaj yeem tiv taus UT teev hauv tus qauv.

Muaj ntawv pov thawj hauv tsev thiab txawv teb chaws

Thaum kawg, nws tseem yog ib qho tseem ceeb los xaiv cov khoom lag luam nrog cov ntawv pov thawj thib peb (xws li CE, TUV, CAS, CQC, thiab lwm yam), thiab xaiv cov tuam txhab nrog kev sib txuam, kev ua haujlwm zoo, thiab cov kev daws teeb meem zoo.

Raws li TUV, CE, CQC thiab lwm yam ntaub ntawv pov thawj thoob ntiaj teb, lub surge protector muaj cov cuab yeej tsim khoom zoo heev thiab kev siv thev naus laus zis hauv kev tiv thaiv xob laim, thiab tuaj yeem ua tau raws li daim ntawv thov nyob rau hauv cov xwm txheej huab cua xws li kub kub, kub thiab toj siab, thiab tuaj yeem tiv taus tam sim no thiab overvoltage rau lub sijhawm ntev.,Surge tiv thaivtuaj yeem kho tau rau cov neeg siv khoom hauv qhov chaw tshwj xeeb.
