Pehea e koho ai i ka mea hana palekana SPD mea hana
8 mau manaʻo nui o ke kūʻai ʻana mai i nā pono pale pale pluggable mai Kina
LSP mākou he mea hana Kina mai ka 2010, e kia i kā mākou mau hana i ka hoʻomohala ʻana i ka pale o ka piʻi ʻana a me ka hana ʻana o nā hāmeʻe pale AC AC PV, e hoʻoikaika e lawelawe i kā mākou mea kūʻai aku me nā huahana kiʻekiʻe.
Inā he mea lawe lawe uila ʻoe, ʻākena, mea hoʻokaʻawale, mea kūʻai aku a mea kūʻai aku paha, ke kūʻai ʻoe iā AC a me DC a i ʻole PV SPDs (nā mea pale pale), pono ʻoe e ʻike i nā manaʻo nui he 8 o ke kūʻai ʻana i nā pono pale pale pluggable surge (SPD) mai Kina.
1. Mea maka
(1.1) MetalʻOxida Varistor - Mov
Ma ke ʻano he kikowaena o loko o SPD, pono ʻole e ʻōlelo, pili ka maikaʻi o ka SPD i ka maikaʻi varistors. Hoʻomaopopo pono i ka Mov e lilo ana i mea nui, nui a nui nā varistors metala hao kuni kaulana no ke koho e like me EPCOS / TDK, Littelfuse, Keko, Varsi…
