Lub hauv paus qauv ntawm zinc oxide ntes yog lub valve phaj.Lub zinc oxide valve yog rwb thaiv tsev nyob rau hauv qhov kev khiav hauj lwm voltage, thiab qhov dhau tam sim no me me, feem ntau 10 ~ 15μA, thiab cov yam ntxwv tsis zoo ntawm zinc oxide valve feem ntau yog tsim los ntawm cov nplej ciam txheej.Nws tus yam ntxwv volt-ampere nkhaus yog ze rau qhov zoo tshaj plaws ntes.
Ntxiv rau qhov zoo tshaj plaws nonlinearity, zinc oxide ntes kuj muaj cov txiaj ntsig tseem ceeb hauv qab no:
1. Tsis muaj qhov sib txawv.Nyob rau hauv qhov kev txiav txim ntawm kev ua hauj lwm voltage, zinc oxide valve phaj yog qhov sib npaug rau ib qho insulator, uas yuav tsis ua rau nws hlawv.Yog li ntawd, nws muaj peev xwm cais cov kev khiav hauj lwm voltage yam tsis muaj qhov sib txawv series.Vim tias tsis muaj qhov sib txawv, nws tuaj yeem teb sai sai rau qhov kev poob siab nrog lub taub hau siab, thiab qhov tso tawm tsis muaj kev ncua, thiab cov txiaj ntsig ntawm kev txwv overvoltage yog qhov zoo heev.Nws tsis tsuas yog txhim kho kev ntseeg siab ntawm cov khoom siv hluav taws xob tiv thaiv, tab sis kuj txo cov overvoltage ua rau cov khoom siv hluav taws xob, yog li txo qhov ntsuas hluav taws xob ntawm cov khoom siv hluav taws xob.
2. Tsis tas yuav ntws.Los ntawm cov yam ntxwv saum toj no, nws tuaj yeem pom tias tsuas yog thaum qhov hluav taws xob siv rau zinc oxide valve mus txog qhov pib ua haujlwm voltage, "conduction" tshwm sim.Tom qab "kev coj ua", qhov seem seem ntawm zinc oxide valve yog qhov pib zoo ib yam li qhov tam sim no ntws los ntawm nws.Irrelevant tab sis tus nqi tas li.Thaum cov hluav taws xob siv hluav taws xob poob qis dua qhov kev khiav hauj lwm qhov hluav taws xob, qhov "conduction" lub xeev ntawm zinc oxide valve raug txiav, uas yog sib npaug rau cov insulator.Yog li ntawd, tsis muaj hwj chim zaus freewheeling.
