Abstract
【解決手段】酸化亜鉛素子1の周囲に複数本の絶縁支持体4を配置し、酸化亜鉛素子1と複数本の絶縁支持体4を絶縁外皮6で一体的に被覆する。絶縁外皮6の外周面に突設されたひだ間において、酸化亜鉛素子1の表面からの肉厚の薄い薄肉部7を設ける。また、薄肉部7は、絶縁支持体4間に設けられる。
【選択図】図2
Description
図1は、本実施の形態に係る避雷器の構成を示す縦断面図、図2は、図1のA−A矢視横断面図、図3は、図2のB−B矢視縦断面図である。図1〜図3に示すように、本避雷器は、主たる構成要素として、例えば複数積層された非直線抵抗素子としての酸化亜鉛素子1と、酸化亜鉛素子1の上端面に配置された押圧ばね2と、酸化亜鉛素子1および押圧ばね2からなる直列体の両端に配置された一対の端子電極3と、酸化亜鉛素子1の周囲に配置され酸化亜鉛素子1の積層方向に延伸して端子電極3を締結する棒状の複数の絶縁支持体4と、少なくとも直列体の外周を絶縁支持体4と一体的に覆う絶縁外皮6と、を備えている。
