Hlau oxide varistor
Apr 23, 2021
Qhov hloov pauv feem ntau yog cov hlau hloov pauv hlau (MOV, Hlau Oxide Varistor), uas muaj cov nplais pob zeb ua los ntawm cov zinc oxide hais me me thiab me me ntawm lwm cov hlau oxides lossis polymers, sib npaug ntawm ob daim hlau.
Cov nyhuv diode yog tsim los ntawm kev sib tshuam ntawm cov khoom thiab cov oxides uas nyob ib sab. Vim tias muaj ntau qhov tsis meej, nws sib npaug rau ntau qhov rov qab txuas nrog diodes. Ntawm qhov hluav taws xob qis, tsuas muaj qhov me me thim rov qab tam sim no. Thaum ntsib qhov hluav taws xob siab, cov diode Rov qab sib tsoo tshwm sim vim kub cov hluav taws xob thiab qhov ua kom zoo, thiab muaj dej ntws loj.
Yog li ntawd, qhov tam sim no-voltage yam ntxwv nkhaus ntawm tus varistor yog qhov tsis sib xws: siab tiv taus ntawm qhov hluav taws xob qis thiab tiv taus qis ntawm qhov hluav taws xob siab.
