The top and the bottom of a ceramic spacer for sustaining an electrode gap in a surge arrester contact with electrodes, in which there are triple junction points formed among the ceramic spacer, the gap electrodes, and the atmosphere. Electric field at the triple-junction point becomes large; therefore, the triple junction point may influence the discharge characteristics. We prepared some electrodes with a small step edge on an inclined plane of each electrodes, which played a role like a triple junction point. We investigated how the shape of the electrodes influences on discharge characteristics such as discharge ignition. The results showed that formation of a step edge on an inclined plane of each electrode contribute on lowering a discharge voltage and shortening a discharge time lag.}, pages = {155--158}, title = {直列ギャップ付ZnO避雷器のV-t特性の改善に関する研究}, volume = {46}, year = {2016}, yomi = {ホリエ, ヒビキ and サコダ, タツヤ and クボ, カツタカ and ミズタニ, マナブ and フカノ, タカト and ホリエ, ヒビキ and クボ, カツタカ and ミズタニ, マナブ and フカノ, タカト} }
