Claims (2)
- 積層された非直線抵抗素子と、
この非直線抵抗素子の積層方向の両側に配置された一対の端子電極と、
前記非直線抵抗素子の周囲に複数本配置され、それぞれ前記積層方向に延伸するとともに、前記一対の端子電極を連結する絶縁支持体と、
シリコーンゴムを材料として形成され、前記非直線抵抗素子と前記複数本の絶縁支持体とを一体的に被覆するとともに、外周面に突設された複数のひだを有する絶縁外皮と、
を備え、
前記絶縁外皮の前記ひだ間に前記非直線抵抗素子の表面からの肉厚の薄い薄肉部が前記ひだ間にわたって設けられており、
前記薄肉部は、前記絶縁外皮の周方向における前記絶縁支持体間に設けられるとともに、前記積層方向に沿ってスリット状にすべてのひだ間に設けられて前記絶縁外皮の周方向における位置を同一として直線的に延在しており、
前記薄肉部は、前記絶縁外皮の外面に凹状に設けられており、
前記薄肉部は、前記周方向に2個設けられているとともに径方向に対向して設けられており、
前記絶縁外被は、短絡電流の通電時に発生するアークガスによっていずれか一つの前記薄肉部が開口すると、この開口した薄肉部が起点となり前記積層方向に沿って直線的に延在している他の薄肉部も開口し、前記積層方向に裂けて開口することを特徴とする避雷器。 - 前記薄肉部を隣接機器とは異なる方向に向けて設置したことを特徴とする請求項1に記載の避雷器。
