ʻO ke kumu kumu o ka zinc oxide arrester ʻo ka pā valve.Hoʻopili ʻia ka valve zinc oxide ma lalo o ka volta hana, a he liʻiliʻi loa ke kahe o kēia manawa, ma ke ʻano he 10 ~ 15μA, a ʻo nā hiʻohiʻona nonlinear o ka valve zinc oxide i hoʻokumu ʻia e ka papa palena o ka palaoa.ʻO kona ʻano volt-ampere ʻano ʻokoʻa kokoke i kahi mea hopu kūpono.
Ma waho aʻe o ka nonlinearity maikaʻi loa, loaʻa i nā mea hopu zinc oxide nā pono nui aʻe:
1. ʻAʻohe kaʻawale.Ma lalo o ka hana o ka volta hana, ua like maoli ka zinc oxide valve plate me kahi insulator, ʻaʻole ia e hoʻopau ʻia.No laila, hiki ke hoʻokaʻawale i ka volta hana me ka ʻole o ke kaʻe.No ka mea, ʻaʻohe wahi āpau, hiki iā ia ke pane koke i ka nalu haʻalulu me ke poʻo kiʻekiʻe, a ʻaʻohe lohi o ka hoʻokuʻu ʻana, a maikaʻi loa ka hopena o ka palena o ka overvoltage.ʻAʻole ia e hoʻomaikaʻi wale i ka hilinaʻi o ka pale ʻana i nā lako mana, akā e hōʻemi ana hoʻi i ka overvoltage e hana ana i nā mea hana mana, a laila e hōʻemi i ka pae insulation i helu ʻia o nā mea mana.
2. ʻAʻohe kahe mau.Mai nā hiʻohiʻona i luna nei, hiki ke ʻike ʻia i ka wā wale nō i hoʻopili ʻia ka volta i ka valve zinc oxide i ka volta hana mua, hiki ke "conduction".Ma hope o ka "conduction", ʻo ke koena o ka volta ma ka pahu zinc oxide e like me ke kahe e kahe ana i loko.Pili ʻole akā he waiwai mau.Ke hāʻule ka volta i hoʻohana ʻia ma lalo o ka volta hana, ua hoʻopau ʻia ke kūlana "conduction" o ka valve zinc oxide, e like me ka insulator.No laila, ʻaʻohe mana alapine freewheeling.
