Nrog rau txoj kev loj hlob sai ntawm kev lag luam automation, lub tsev ntse, lub zog tshiab thiab cov ntaub ntawv chaw tsim kho, cov khoom siv hluav taws xob xav tau ntau thiab ntau lub zog zoo thiab kev ua haujlwm ruaj khov. Txawm li cas los xij, xob laim tawm tsam, hloov daim phiaj hluav taws xob, cov cuab yeej pib thiab kaw tuaj yeem ua rau tag nrho cov hluav taws xob overvoltages (surges), uas tuaj yeem ua rau cov cuab yeej tsis ua haujlwm, kaw lub kaw lus thiab txawm tias cov khoom puas tsuaj.
Raws li cov chaw tsim khoom ntawm surge protector, peb feem ntau ntsib tib cov lus nug los ntawm peb cov neeg siv khoom: Yuav ua li cas xaiv tus tiv thaiv surge rau koj qhov project?
Qhov tseeb, cov haujlwm sib txawv muaj qhov sib txawv ntawm kev tiv thaiv kev tiv thaiv kev xav tau. Xaiv cov khoom raws li tus nqi lossis kev qhia tshwj xeeb yuav tsis ua tiav qhov kev tiv thaiv uas xav tau. Kab lus no yuav pab koj nkag siab txog ntau yam tseem ceeb uas yuav tsum tau saib xyuas thaum xaiv SPD los ntawm kev pom zoo ntawm daim ntawv thov.
1. Ua ntej, txhais qhov project thov scenario.
Ua ntej xaiv tus tiv thaiv surge, qhov tseem ceeb tshaj plaws kom nkag siab yog qhov twg los nruab lub cuab yeej.
