Siv lub zog faib hluav taws xob raws li kev siv, surges tuaj yeem muab faib ua ob hom: sab nraud thiab sab hauv. Kev txheeb cais qhia tau hais tias sab nraud surges feem ntau yog los ntawm xob laim thiab lwm yam kev cuam tshuam, suav txog kwv yees li 20%; Internal surges feem ntau yog los ntawm qhov cuam tshuam ntawm cov khoom hluav taws xob sab hauv, suav txog kwv yees li 80%.
Hom Surges thiab Kev Ntsuas Zoo
Sab nraud surges yog mem tes-zoo li surges, raws li qhia hauv daim duab hauv qab no. Hom kev nce siab no feem ntau tshwm sim los ntawm sab nraud lub cev thiab yog tus cwj pwm los ntawm tus nqi siab heev tam sim ntawd, nce los ntawm ntau pua ntawm volts mus rau 20,000 volts hauv ob peb microseconds. Raws li qhov tshwm sim no, peb siv cov cuab yeej hluav taws xob hluav taws xob hluav taws xob txhawm rau txhawm rau nce siab tshaj tus nqi ruaj khov ntawm qhov hluav taws xob sinusoidal. Qhov no yog ib qho kev daws teeb meem zoo thiab siv tau rau kev tiv thaiv cov khoom siv hluav taws xob, tshwj xeeb tshaj yog muaj txiaj ntsig zoo tiv thaiv siab - zog pulse- zoo li surges generated sab nraud.
Internal surges yog oscillating surges, raws li qhia hauv daim duab hauv qab no. Hom surge no yog tus cwj pwm los ntawm kev nce ntawm ntau pua ntawm volts mus rau 6000 volts nyob rau hauv ob peb microseconds mus rau milliseconds. Raws li cov yam ntxwv no, peb siv cov cuab yeej siv hluav taws xob taug qab network. Lub hnab ntawv surge suppression hloov nrog sine yoj, ua rau nws muaj txiaj ntsig zoo tshaj plaws tiv thaiv sab hauv oscillating surges. Nws tuaj yeem ntes cov surges sai thiab kaw lawv hauv lub hnab ntawv sine yoj.
Kev Tiv Thaiv Kev Tiv Thaiv
Standard surge protectors xa tam sim no los ntawm lub hwj chim qhov hluav taws xob mus rau ntau yam khoom siv hluav taws xob thiab hluav taws xob ntsaws rau hauv lub hwj chim board. Yog hais tias muaj ib qho surge los yog spike tshwm sim, ua rau lub voltage ntau tshaj qhov tau txais, lub surge protector diverts cov tshaj tam sim no mus rau lub hwj chim qhov hluav taws xob hauv av hlau.
Feem ntau cov surge protectors muaj cov khoom siv hu ua Hlau Oxide Varistor (MOV) kom hloov hluav taws xob ntau dhau. Raws li pom nyob rau hauv daim duab, lub MOV txuas cov nyob hlau thiab hauv av hlau ua ke.
Lub MOV muaj peb ntu: cov khoom siv hlau oxide nyob rau hauv nruab nrab, thiab ob lub semiconductors txuas lub zog thiab hauv av xaim.
Cov semiconductors no muaj qhov sib txawv tsis sib xws uas hloov nrog qhov voltage. Thaum qhov hluav taws xob qis dua ib qho nqi, kev txav ntawm electrons hauv semiconductor generates tsis tshua muaj siab tsis kam.
Ib qho surge, tseem hu ua ib qho kev hloov hluav taws xob hloov pauv, yog qhov tam sim no overvoltage tshaj qhov kev ua haujlwm voltage. Qhov tseem ceeb, kev nce siab yog ib qho kev ua pa nyuaj uas tshwm sim hauv ib feem ntawm ib pliag. Tej yam uas yuav tshwm sim muaj xws li cov khoom siv hnyav, luv luv, hloov hluav taws xob, lossis lub cav loj. Cov khoom uas muaj surge tiv thaiv cov cuab yeej tuaj yeem nqus tau sai sai, lub zog loj los tiv thaiv cov cuab yeej txuas los ntawm kev puas tsuaj. Surge protectors, tseem hu ua xob laim ntes, yog cov khoom siv hluav taws xob uas muaj kev tiv thaiv kev nyab xeeb rau ntau yam khoom siv hluav taws xob, cov cuab yeej siv, thiab cov kab sib txuas lus. Thaum muaj hluav taws xob tam sim no lossis qhov hluav taws xob tam sim no tshwm sim hauv hluav taws xob los yog kab sib txuas lus vim muaj kev cuam tshuam sab nraud, tus tiv thaiv hluav taws xob tuaj yeem ua thiab hloov qhov tam sim no nyob rau lub sijhawm luv luv, yog li tiv thaiv kev puas tsuaj rau lwm yam khoom hauv Circuit Court.
