Surge Protector Function Txoj Cai Thiab Cov Kab Xaim

Tus tiv thaiv tiv thaiv kuj tseem hu ua (tus tiv thaiv tiv thaiv) (SPD kom luv). Nws yog qhov tsim nyog rau AC 50/60HZ, ntsuas hluav taws xob 220V txog 380V cov khoom siv hluav taws xob (lossis kev sib txuas lus), thiab nws tuaj yeem cuam tshuam rau xob laim ncaj qha thiab xob laim ncaj qha lossis lwm yam kev hloov pauv. Kev tiv thaiv kev tiv thaiv hluav taws xob tsim nyog rau qhov xav tau ntawm kev tiv thaiv kev nyab xeeb hauv tsev neeg, kev lag luam qib siab thiab kev lag luam. Nws muaj theem-rau-theem, theem-rau-ntiaj teb, theem-rau-nruab nrab, nruab nrab-rau-lub ntiaj teb, thiab kev sib txuas ua ke ntawm kev tiv thaiv hom.

Surge kuj tseem hu ua nthwv dej, uas yog qhov hluav taws xob tam sim ntawd uas dhau ntawm qhov ua haujlwm ib txwm muaj. Qhov tseem ceeb, kev nce siab yog lub plawv dhia nrawm uas tshwm sim hauv ob peb plhom plhom ntawm ib pliag. Qhov ua tau tuaj yeem ua rau muaj kev cuam tshuam yog: cov cuab yeej hnyav, hloov pauv luv, hloov lub zog, lossis cov cav loj. Cov khoom lag luam uas muaj cov khoom thaiv thaiv tau tuaj yeem nqus tau lub zog loj tam sim los tiv thaiv cov cuab yeej txuas los ntawm kev puas tsuaj. Surge protector, tseem hu ua tus tiv thaiv xob laim, yog cov cuab yeej hluav taws xob uas muab kev tiv thaiv kev nyab xeeb rau ntau yam khoom siv hluav taws xob, cov twj paj nruag, thiab kab sib txuas lus. Thaum qhov hluav taws xob tam sim no lossis qhov hluav taws xob tau tshwm sim tam sim ntawd hauv hluav taws xob Circuit Court lossis kev sib txuas lus Circuit Court vim muaj kev cuam tshuam sab nraud, tus tiv thaiv kev tiv thaiv tuaj yeem ua thiab tshem tawm hauv lub sijhawm luv luv, thiaj li tiv thaiv kev nce los ntawm kev puas tsuaj lwm yam cuab yeej hauv Circuit Court.

Tus tiv thaiv kev tiv thaiv kuj tseem nrog kev nce qib ntawm zej zog, tshwj xeeb hauv cov tsev tshiab.

Cov txheej txheem tiv thaiv kev tiv thaiv

Tus txheej txheem tiv thaiv kev tiv thaiv yuav xa tawm tam sim no los ntawm lub qhov hluav taws xob mus rau ntau yam khoom siv hluav taws xob thiab khoom siv hluav taws xob ntsaws rau hauv pawg tswj hwm lub zog. Yog tias muaj qhov nce lossis qhov tshwm sim tshwm sim thiab qhov hluav taws xob siab tshaj qhov lees paub, tus tiv thaiv kev tiv thaiv yuav hloov qhov tam sim no mus rau hauv av ntawm lub qhov hluav taws xob.

Hauv kev tiv thaiv kev tiv thaiv feem ntau, muaj ib lub npe hu ua Hlau Oxide Varistor (MOV), uas yog siv los hloov qhov hluav taws xob ntau dhau.

MOV muaj peb ntu: hauv nruab nrab yog cov khoom siv hlau oxide, thiab ob lub semiconductors txuas nrog lub hwj chim thiab hauv av.

& quot; Cov semiconductors no muaj qhov tsis sib xws uas hloov pauv nrog kev hloov pauv hauv qhov hluav taws xob. Thaum qhov hluav taws xob qis dua tus nqi tshwj xeeb, kev txav ntawm cov hluav taws xob hauv cov khoom siv hluav taws xob yuav ua rau muaj kev tiv thaiv siab heev. Hloov pauv, thaum qhov hluav taws xob ntau tshaj qhov tshwj xeeb no, kev txav ntawm cov hluav taws xob yuav hloov pauv, thiab qhov tsis kam ntawm cov khoom siv hluav taws xob yuav raug txo qis. Yog tias qhov hluav taws xob zoo li qub, MOV yuav tsis ua haujlwm. Thaum qhov hluav taws xob siab dhau lawm, MOV tuaj yeem ua rau muaj ntau qhov tam sim no thiab tshem tawm qhov hluav taws xob ntau dhau.

Raws li qhov tam sim no ntau dhau tau xa mus rau hauv av xaim ntawm MOV, cov xov hlau nyob qhov hluav taws xob yuav rov zoo li qub, ua rau qhov tsis kam ntawm MOV nce ntxiv sai dua. Hauv txoj kev no, MOV tsuas yog hloov pauv qhov kev nce siab tam sim no, thaum tso cai rau tus qauv tam sim no txuas ntxiv txuas lub hwj chim cov cuab yeej txuas nrog tus tiv thaiv kev tiv thaiv. Piv txwv li, MOV ua zoo li lub siab-rhiab valve, qhib tsuas yog thaum lub siab siab dhau.
