Txoj Cai Ua Haujlwm Ntawm Surge Protector

Ib qho khoom siv tiv thaiv hluav taws xob (SPD) yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob tiv thaiv hluav taws xob. Yav tas los hu ua " xob laim ntes" lossis "overvoltage protector," nws cov lus Askiv yog SPD. Kev ua haujlwm ntawm tus tiv thaiv hluav taws xob yog txwv tsis pub dhau lub sijhawm dhau los nkag rau hauv cov kab hluav taws xob lossis cov kab hluav taws xob xa mus rau hauv qhov hluav taws xob ntau yam uas cov khoom siv lossis lub kaw lus tuaj yeem tiv taus, lossis cuam tshuam cov hluav taws xob hluav taws xob muaj zog rau hauv av, tiv thaiv cov cuab yeej tiv thaiv lossis kev puas tsuaj los ntawm kev tawg.

Hom thiab cov qauv ntawm surge protectors sib txawv nyob ntawm lawv daim ntawv thov, tab sis lawv yuav tsum tsawg kawg suav nrog ib qho tsis yog -linear voltage limiting element. Cov khoom siv tseem ceeb siv hauv cov khoom tiv thaiv hluav taws xob muaj xws li: cov pa tawm tawm, cov pa roj- cov raj xa tawm, cov varistors, cov diodes tiv thaiv, thiab choke coils.
