Qhov cuam tshuam ntawm Cable ntev ntawm Kev Tiv Thaiv Qib Siab Tiv Thaiv Ntaus
Lub ntsiab lus ntawm kev txhim kho SPD tsis tshua pom hauv peb cov kev sib tham. Muaj ob qho laj thawj no:
- Kev teeb tsa ntawm cov khoom thaiv hluav taws xob tiv thaiv yuav tsum tau ua los ntawm ib tus kws tsim hluav taws xob tsim nyog. Peb tsis xav yuam kev tias qhov no yuav tsum tau ua los ntawm cov neeg siv. Thiab yog tias SPD tsis muaj xaim tsis raug, nws yuav ua rau muaj teeb meem.
- Muaj ntau ntau cov yeeb yaj duab nyob rau Youtube ua qhia yuav ua li cas rau nruab ib qho kev tiv thaiv kev tiv thaiv. Nws yog qhov yooj yim thiab yooj yim dua nyeem ntawv cov lus qhia.
Tiam sis tseem, peb pom tau yuam kev heev hauv kev txhim kho SPD, txawm los ntawm kev ua haujlwm. Yog li nyob rau hauv tsab xov xwm no, peb yuav los sib tham txog ib qho tseem ceeb hauv kev txhim kho kev tiv thaiv kev tiv thaiv: kom lub xov tooj kom luv li sai tau.
Vim li cas cov cable ntev tseem ceeb?
Koj yuav nug koj tus kheej li lo lus nug no. Thiab qee zaum peb nug los ntawm cov neeg siv khoom lag luam tias vim li cas koj tsis tuaj yeem ua rau SPD cov xov tooj ntev? Yog tias koj ua cov cable ntev ntev, tom qab ntawd kuv tuaj yeem nruab SPD me ntsis kom deb ntawm kab kev sib kis. Zoo, qhov ntawd yog qhov fab ntxeev ntawm cov chaw tsim khoom SPD xav kom koj ua.
Ntawm no peb ua kom paub ib qho parameter: VPR (Voltage Protection Rating) lossis Siab (clamping voltage). Tus qub hauv UL txuj thiab tus tom kawg yog hauv IEC tus qauv. Nkag qhov txawv ntawm lawv cov kev sib txawv, lawv qhia cov tswv yim zoo sib xws: ntau npaum li cas dhau qhov hluav taws xob uas SPD yuav pub kom dhau mus rau cov khoom siv nqes. Hauv hom lus, nws kuj yog hu ua qhov tsis sib txuas lus.
Txoj kab xev ntev muaj feem rau qhov cia-dhau ntawm qhov hluav taws xob. Cia saib hauv qab no ob qho kev tso cai-hla kev ntsuas.
Tej zaum koj yuav xav tias thawj SPD ua rau ntau tshaj qhov thib ob. Tab sis li cas txog peb qhia rau koj tias cov no yog tus cia los ntawm voltage ntawm tus tib surge tiv thaiv ntaus ntawv? Yog, qhov no yog qhov tseeb. Qhov no yog cov ntaub ntawv los ntawm kev sim ua los ntawm EATON. Los ntawm kev ua kom ntev ntev los ntawm 3ft, cia ntawm kev sib tw yuav luag ob zaug qhia tias muaj kev tiv thaiv tsis zoo heev rau cov khoom siv nqes.
Muaj ib txoj cai dav dav uas 1 meter ntawm cable hla los ntawm ib lub teeb xob tam sim no ua rau muaj kev sib tshuam ntawm 1,000V.

Cable ntev muaj qhov muaj zog rau kev tiv thaiv theem ntawm kev tiv thaiv kev tiv thaiv kabmob. Yog li ntawd yeej ib txwm nco ntsoov kom lub xov tooj kom luv li sai tau thaum txhim kho ib qho kev tiv thaiv kabmob. Txwv tsis pub, koj cov nyiaj tso rau kev tiv thaiv kom txhob muaj kev tiv thaiv yog khib nyiab thiab koj tsuas yog muaj kev ruaj ntseg ntawm kev ruaj ntseg.
