Txoj cai ntawm kev tiv thaiv overvoltage ntawm cov khoom siv hluav taws xob ntau zaus

Kev ntsuas ntawm kev tiv thaiv overvoltage yog siv lub varistor nyob rau hauv parallel nrog ob kawg ntawm lub hwj huam mov kab. Lub varistor yog rhiab heev rau voltage. Thaum qhov hluav taws xob ntau tshaj ib qho nqi, nws qhov kev tiv thaiv tam sim ntawd ua me me, yog li qhov tam sim no nce sharply. Thaum lub cuab yeej muaj overvoltage, nws yuav ua txhaum lub varistor, yog li ntawd ob qho tag nrho ntawm lub hwj huam mov yuav raug txiav, yog li tiv thaiv lub nraub qaum kawg ntawm lub hwj huam mov thiab tsis txhob muaj kev pheej hmoo ntawm overvoltage, uas ua hauj lwm rau lub hom phiaj ntawm kev tiv thaiv overvoltage. Ntev npaum li lub varistor hloov ntau zaus, cov cuab yeej siv tau ib txwm siv, tab sis peb yuav tsum hloov lub varistor hauv lub sijhawm, uas yog lub zog ua haujlwm. Yog tias nws tsis tuaj yeem hloov tau raws sijhawm, cov khoom siv hluav taws xob yuav raug puas ntsoog, thiab txawm tias hluav taws kub hnyiab tuaj yeem tshwm sim hauv qhov xwm txheej hnyav.

Kev tiv thaiv overvoltage thiab kev tiv thaiv undervoltage ntawm high-frequency quenching khoom yog ib qho tseem ceeb heev. Ntev npaum li tus nqi hluav taws xob ntawm peb cov khoom siv tshaj qhov pib, qhov taw qhia lub teeb ntawm cov cuab yeej yuav teeb thiab lub tswb yuav raug tso tawm. Lub sijhawm no, cov neeg ua haujlwm yuav tsum tau ntsuas tam sim ntawd kom tsis txhob muaj qhov xwm txheej ntawm cov khoom zoo dua qub kuj tiv thaiv qhov tshwm sim ntawm cov teeb meem xws li hluav taws kub. Nws muaj kev nyab xeeb thiab ua haujlwm zoo.
