Surge tiv thaiv rau cov khoom siv hluav taws xob Nws kwv yees tias 75% ntawm kev ua tsis tiav hauv cov khoom siv hluav taws xob yog tshwm sim los ntawm kev hloov pauv thiab nce ntxiv. Voltage transients thiab surges nyob txhua qhov chaw. Cov kab hluav taws xob, hluav taws xob, hluav taws xob, thiab txawm tias cov neeg taug kev ntawm cov ntaub pua plag yuav tsim ntau txhiab tus volts ntawm electrostatically induced voltage. Cov no yog cov tsis pom kev tua neeg ntawm cov khoom siv hluav taws xob. Yog li ntawd, txhawm rau txhim kho kev ntseeg siab ntawm cov khoom siv hluav taws xob thiab kev nyab xeeb ntawm tib neeg lub cev, nws yog ib qho tsim nyog yuav tsum tau ua kev tiv thaiv kev tiv thaiv hluav taws xob hloov pauv thiab surges. Muaj ntau qhov laj thawj rau kev nce siab. Lub surge yog ib tug spike nrog ib tug siab ntawm nce thiab ib tug luv luv lub sij hawm. Cov hluav taws xob hluav taws xob overvoltage, hloov hluav taws xob, rov qab qhov chaw, hluav taws xob zoo li qub, lub cev muaj zog / lub suab nrov, thiab lwm yam yog txhua yam uas ua rau muaj kev kub ntxhov. Lub surge protector muab ib txoj hauv kev yooj yim, kev lag luam thiab txhim khu kev qha tiv thaiv kev tiv thaiv hluav taws xob tiv thaiv hluav taws xob. Raws li peb txhua tus paub, cov khoom siv hluav taws xob feem ntau ntsib qhov kev xav tsis zoo ntawm cov khoom siv hluav taws xob thiab kev nce siab thaum siv, ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob. Qhov kev puas tsuaj yog tshwm sim los ntawm cov khoom siv semiconductor hauv cov khoom siv hluav taws xob (xws li diodes, transistors, thyristors thiab integrated circuits, thiab lwm yam) raug hlawv tawm lossis tawg. Thawj txoj kev tiv thaiv yog siv kev sib xyaw ua ke ntawm ntau qhov hluav taws xob hloov hluav taws xob thiab kev tiv thaiv hluav taws xob rau cov khoom tseem ceeb thiab kim ua tiav cov tshuab thiab cov tshuab los tsim ib qho kev tiv thaiv ntau theem. Qhov thib ob txoj kev tiv thaiv yog av tag nrho lub tshuab thiab lub cev. Hauv av (qhov kawg) ntawm tag nrho lub tshuab thiab lub kaw lus yuav tsum tau muab cais tawm ntawm lub ntiaj teb. Tag nrho lub tshuab thiab txhua lub subsystem nyob rau hauv lub system yuav tsum muaj ib qho kev ywj siab kawg. Thaum xa cov ntaub ntawv lossis cov cim qhia, cov av yuav tsum tau siv raws li qib siv, thiab hauv av xaim (nto) yuav tsum muaj peev xwm ntws mus rau qhov tam sim no loj, xws li ntau pua amperes. Txoj kev tiv thaiv thib peb yog siv cov khoom siv hluav taws xob hloov hluav taws xob thiab kev tiv thaiv hluav taws xob hauv tag nrho lub tshuab thiab qhov tseem ceeb ntawm lub cev (xws li lub khoos phis tawj saib, thiab lwm yam), kom cov hluav taws xob hloov hluav taws xob thiab cov surges hla mus rau hauv av subsystem thiab subsystem los ntawm cov cov cuab yeej tiv thaiv. hauv av, kom lub sijhawm hloov pauv hluav taws xob thiab cov surge amplitude nkag mus rau tag nrho lub tshuab thiab lub cev raug txo qis heev. Lub surge protector muab ib txoj hauv kev yooj yim, kev lag luam thiab txhim khu kev qha tiv thaiv kev tiv thaiv hluav taws xob tiv thaiv hluav taws xob. Los ntawm kev tiv thaiv kev tiv thaiv hluav taws xob (MOV), lub zog hluav taws xob tuaj yeem nkag mus sai sai rau hauv qhov hluav taws xob induction thiab kev khiav hauj lwm overvoltage. Lub ntiaj teb, tiv thaiv cov cuab yeej los ntawm kev puas tsuaj.
