Txawm hais tias lub surge reserve tiv thaiv yuav tsum tau hloov tom qab xob laim tawm tsam lossis surge nyob ntawm qhov kev puas tsuaj thiab kev hloov pauv hauv kev ua haujlwm. Kev tsom xam tshwj xeeb yog raws li hauv qab no:
I. Cov xwm txheej yuav tsum tau hloov
Kev puas tsuaj mus tas li rau cov khoom siv
Cov khoom tseem ceeb ntawm surge surge protectors xws li MOV varistors thiab GDT gas paug hlab, tuaj yeem ua kom sov, poob kev ua haujlwm lossis tawg tom qab nqus lub zog. Yog kuaj pom:
Ntxiv MOV to tam sim no, tshav kub, los yog tiv thaiv luv luv Circuit Court;
GDT ignition voltage drift, teb qeeb, los yog iav raj lub cev darkening nrog hlau deposits residue ntawm electrodes;
Thaum lub fuse melts (qhov tseeb surge tam sim no tshaj qhov ntsuas tus nqi), hloov cov khoom siv los yog tag nrho cov surge protector yuav tsum tau.
Kev ua haujlwm poob qis
Txawm tias tsis muaj qhov ua txhaum loj, kev raug nthwv dej ntev ntev lossis hnyav hnyav (xws li qhov kub thiab txias, av noo thiab ntsev pos huab) tuaj yeem ua rau muaj hnub nyoog raws li hauv qab no:
Txwv tsis pub muaj peev xwm txo qis (piv txwv li U1mA ntau dua 10%);
Lub sij hawm teb tau ntev dua thiab lub zog surge tsis tawm hauv lub sijhawm.
Nyob rau lub sijhawm no, kev ntsuas kev tshaj lij (xws li ntsuas qhov seem seem thiab cov xau tam sim no) yuav tsum tau ua kom paub meej tias kev ua haujlwm. Yog tias nws tshaj li tus qauv ntau, nws yuav tsum tau hloov tam sim ntawd.
Qhov tshwm sim lossis kev puas tsuaj
Yog hais tias lub surge protector lub plhaub melts, deforms, qhov taw qhia lub teeb tsis ua hauj lwm zoo los yog lub installation ib puag ncig ua rau tiv thaiv corrosion (xws li cov ntug dej hiav txwv ntsev pos huab infiltration), nws yuav tsum tau muab hloov kom ruaj ntseg.
II. Qhov xwm txheej ib ntus irreplaceable
Ib txwm tsis siv neeg rov pib ua haujlwm
Qee qhov siab -cov khoom tiv thaiv zoo tuaj yeem rov qab los ntawm qhov tsis tshua muaj kev tiv thaiv siab tom qab ib qho kev cuam tshuam, thiab qhov tseeb tias qhov taw qhia qhov rai tsis hloov xim (xws li, los ntawm ntsuab mus rau liab) txhais tau tias lawv tseem ua haujlwm thiab tsis tas yuav hloov tam sim ntawd.
Tsis ncav cuag tus tsim lifespan
surge protector feem ntau yog tsim los kom kav ntev li 3-5 xyoos (qee yam khoom siv tau ntev txog 10 xyoo). Yog tias kev siv luv luv thiab tsis muaj kev cuam tshuam ntau zaus, txawm tias ib qho kev tawm tsam xob laim yuav tsis xav tau kev hloov pauv, tab sis kev soj ntsuam xyuas yuav tsum tau ntxiv dag zog.
III. Kev xa thiab hloov cov lus pom zoo
Kev tshuaj xyuas ib ntus thiab kaw
Kev soj ntsuam pom tsawg kawg ib xyoos ib zaug kom pom tias sab nrauv puas puas lawm thiab qhov taw qhia lub teeb yog qhov qub;
Thaum lub caij los nag, nws yog ib qho tseem ceeb uas yuav tsum tau xyuas thiab sau cov keeb kwm kev txij nkawm ntawm cov surge protector thiab nkag siab txog kev laus ntawm cov surge protectors.
Kev xeem kev tshaj lij
Cov tsis xws li qhov seem voltage thiab to tam sim no yog ntsuas siv cov cuab yeej tshwj xeeb. Yog tias qhov ntsuas tsis dhau tus qauv ntau (xws li cov dej ntws tawm> 20μA), lawv yuav tsum tau hloov tam sim ntawd.
Kev tiv thaiv kev hloov pauv
Cov cua daj cua dub raug pom zoo kom hloov txhua 3 mus rau 5 xyoos hauv thaj chaw uas lawv nquag, xws li sab qab teb;
Txawm hais tias cov kev txwv no yog 合格, lawv yuav tsum tau txiav txim siab hloov tom qab 5 xyoos ntawm kev ua haujlwm kom ntseeg tau tias muaj kev tiv thaiv.
Environmental adaptability txij nkawm
Nyob rau hauv qhov kub thiab txias, av noo thiab corrosion ib puag ncig, txo lub voj voog tshuaj xyuas thiab ntxiv dag zog rau kev tiv thaiv kev ntsuas (xws li txhim kho cov thawv tiv thaiv);
Yog tias muaj teeb meem tshwm sim hauv cov av hauv av (xws li kev tiv thaiv hauv av siab), kev saib xyuas raws sij hawm yuav tsum tau ua kom tsis txhob muaj qhov txhaum ntawm kev tiv thaiv kev tiv thaiv vim tsis zoo hauv av.
