Isakhiwo esisisiseko se-zinc oxide arrester yipleyiti yevalve.Ivalve ye-oxide ye-zinc ifakwe phantsi kombane osebenzayo, kwaye i-current current incinci kakhulu, ngokubanzi i-10 ~ 15μA, kunye neempawu ezingabonakaliyo ze-valve ye-oxyde ye-zinc zenziwa ikakhulu ngumaleko womda wengqolowa.Igophe layo leempawu ze-volt-ampere likufutshane nelokubamba okufanelekileyo.
Ukongeza kokungahambelani okugqwesileyo, izibambi ze-zinc oxide nazo zineenzuzo eziphambili zilandelayo:
1. Akukho msantsa.Ngaphantsi kwesenzo sombane osebenzayo, ipleyiti yevalve ye-zinc oxide ngokwenene ilingana ne-insulator, engayi kubangela ukuba iphele.Ngoko ke, kunokwenzeka ukwahlula i-voltage yokusebenza ngaphandle kwe-gap yochungechunge.Ngenxa yokuba akukho msantsa, inokusabela ngokukhawuleza kwi-wave shock ngentloko enqabileyo, kwaye ukukhutshwa akunakulibaziseka, kwaye umphumo wokunciphisa ukugqithisa kulungile kakhulu.Ayiphuculi nje kuphela ukuthembeka kokhuseleko lwezixhobo zamandla, kodwa ikwanciphisa i-overvoltage esebenza kwisixhobo sombane, ngaloo ndlela inciphisa inqanaba lokugquma elilinganisiweyo lezixhobo zamandla.
2. Akukho kuqukuqela okuqhubekayo.Ukususela kwiimpawu ezingentla, kunokubonwa ukuba kuphela xa i-voltage esetyenziswe kwi-valve ye-zinc oxide ifikelela kumbane wokuqala wokusebenza, "ukuqhuba" kwenzeka.Emva "kwe-conduction", i-voltage eseleyo kwi-valve ye-zinc oxide ifana ngokusisiseko nokuhamba kwayo.Ayinamsebenzi kodwa ixabiso elihlala lihleli.Xa i-voltage esetyenzisiweyo ihla ngaphantsi kwe-voltage yokusebenza, imeko "yokuqhuba" ye-valve ye-zinc oxide iphelile, elingana ne-insulator.Ke ngoko, akukho frequency yamandla esimahla.
