Chimiro cheiyo zinc oxide arrester ndiyo ndiro yevharuvhu.Iyo zinc oxide valve yakavharidzirwa pasi pemagetsi ekushanda, uye ikozvino inopfuura iduku zvikuru, kazhinji 10 ~ 15μA, uye maitiro asina mutsara we zinc oxide valve anonyanya kuumbwa nemuganhu wezviyo.Yayo volt-ampere hunhu curve iri padyo neiyo yeakanaka kusunga.
Kuwedzera kune yakanakisa nonlinearity, zinc oxide inosunga zvakare ine zvinotevera zvakakosha zvakanaka:
1. Hapana gap.Pasi pechiito chekushanda voltage, zinc oxide valve plate inenge yakaenzana ne insulator, iyo isingazoiti kuti ipise.Nokudaro, zvinokwanisika kuparadzanisa magetsi ekushanda pasina mutsara wakatevedzana.Nekuti hapana gaka, inogona kukurumidza kupindura kune kuvhunduka wave nemusoro wakadzika, uye kubuda hakuna kunonoka, uye mhedzisiro yekumisa overvoltage yakanaka kwazvo.Iyo haingonatsiridzire kuvimbika kwekudzivirira kwemidziyo yemagetsi, asi zvakare inoderedza kuwandisa kwekuita pamidziyo yemagetsi, nekudaro ichidzikisa iyo yakatemerwa insulation level yemagetsi emagetsi.
2. Hapana kuenderera kuyerera.Kubva pane maitiro ari pamusoro apa, zvinogona kuonekwa kuti chete kana iyo voltage inoshandiswa kune zinc oxide valve inosvika pamagetsi ekutanga ekushanda, "conduction" inoitika.Mushure me "conduction", iyo yakasara voltage pazinc oxide valve yakangofanana neyezvino inoyerera kuburikidza nayo.Hazvina basa asi kukosha kwekugara.Apo simba rinoshandiswa rinodonha pasi pemagetsi ekushanda, "conduction" mamiriro e zinc oxide valve inoguma, iyo yakaenzana ne insulator.Naizvozvo, hapana simba frequency freewheeling.
