Nyob rau hauv lub ntiaj teb niaj hnub no uas siv thev naus laus zis ntau, cov khoom siv hluav taws xob tau dhau los ua ib feem tseem ceeb ntawm peb lub neej txhua hnub, thiab kev ua kom muaj kev nyab xeeb thiab lub neej ntev ntawm cov khoom siv no yog qhov tseem ceeb heev. Thaum muaj hluav taws xob ntau ntxiv, kev nqis peev rau cov khoom siv tiv thaiv hluav taws xob ntau dhau los ua qhov tseem ceeb. Cov khoom siv no muab ib txheej tiv thaiv ntxiv rau kev nce hluav taws xob sai sai uas tuaj yeem ua puas lossis rhuav tshem koj cov khoom siv hluav taws xob.

Cov khoom siv tiv thaiv hluav taws xob ntau dhau (SPDs) yog tsim los hloov cov hluav taws xob ntau dhau ntawm koj cov khoom siv thaum muaj hluav taws xob ntau dhau. Cov hluav taws xob ntau dhau tuaj yeem tshwm sim los ntawm xob laim, kev hloov pauv hluav taws xob, lossis cov khoom siv tsis ua haujlwm. Yog tsis muaj kev tiv thaiv txaus, cov hluav taws xob ntau dhau no tuaj yeem ua rau koj cov khoom siv hluav taws xob puas tsuaj, ua rau muaj kev puas tsuaj uas tsis tuaj yeem kho tau thiab poob nyiaj txiag.

Cov SPDs ua haujlwm los ntawm kev saib xyuas thiab tswj cov hluav taws xob uas ntws mus rau hauv lub cuab yeej. Thaum pom muaj hluav taws xob ntau dhau, lub cuab yeej yuav hloov cov hluav taws xob ntau dhau mus rau hauv av tam sim ntawd, tiv thaiv nws kom tsis txhob mus txog koj cov khoom siv muaj nqis. Qhov no ua kom koj cov khoom siv hluav taws xob tau txais hluav taws xob tas mus li thiab muaj kev nyab xeeb, ua rau lawv lub neej ntev dua thiab zam kev kho lossis hloov pauv kim.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm lub tshuab tiv thaiv hluav taws xob yog nws qhov ua tau ntau yam. Lawv tuaj yeem siv rau hauv tsev nyob, chaw ua lag luam thiab chaw ua haujlwm los tiv thaiv ntau yam khoom siv hluav taws xob. Txij li TV thiab khoos phis tawj mus rau lub tub yees thiab cua txias, txhua yam khoom siv hluav taws xob tuaj yeem tau txais txiaj ntsig los ntawm kev teeb tsa SPD.

Tsis tas li ntawd xwb, cov khoom siv tiv thaiv hluav taws xob tsis tu ncua yooj yim rau kev teeb tsa thiab muab kev daws teeb meem pheej yig los tiv thaiv koj cov khoom siv hluav taws xob. Nrog lawv cov qauv me me, lawv tuaj yeem txuas rau hauv lub qhov hluav taws xob lossis koom ua ke rau hauv lub switchboard. Kev nqis peev rau hauv SPD yog tus nqi me me los them rau kev tiv thaiv mus sij hawm ntev uas nws muab, tej zaum yuav txuag koj pua pua lossis txawm tias ntau txhiab daus las yog tias muaj hluav taws xob ntau dhau.

Thaum xaiv lub cuab yeej tiv thaiv kev poob siab, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov yam xws li clamping voltage, lub sijhawm teb, thiab Joule rating. Clamping voltage sawv cev rau qib voltage uas lub cuab yeej hloov pauv lub zog ntau dhau. Clamping voltage qis dua ua kom muaj kev tiv thaiv zoo dua. Lub sijhawm teb txhais tau tias lub cuab yeej teb sai npaum li cas rau kev poob siab, thaum Joule rating qhia txog lub cuab yeej lub peev xwm los nqus lub zog thaum muaj kev poob siab.

Xaus lus, kev vam khom rau cov khoom siv hluav taws xob ntau ntxiv yuav tsum muaj cov kev ntsuas zoo los tiv thaiv kev nce hluav taws xob. Cov khoom siv tiv thaiv kev nce hluav taws xob yog ib txoj kab tiv thaiv tseem ceeb hauv kev tiv thaiv kev puas tsuaj rau koj cov khoom siv hluav taws xob muaj nqis. Los ntawm kev nqis peev rau hauv SPD, koj tuaj yeem muaj kev thaj yeeb nyab xeeb tias koj cov khoom siv yuav tsis raug cuam tshuam los ntawm kev nce hluav taws xob uas tsis tuaj yeem kwv yees tau thiab yuav kav ntev dua. Ua cov kauj ruam tsim nyog los tiv thaiv koj cov khoom siv hluav taws xob nrog kev tiv thaiv kev nce hluav taws xob hnub no.
