B1 消弧空間
Claims (3)
- 接点間に生じるアークを消弧する消弧装置を備え、
前記消弧装置は、アークを分断する複数の消弧板をその厚み方向に沿って並列に配置した消弧グリッドと、前記消弧グリッドを通過するアークを逃がす消弧空間とを有し、
前記消弧グリッドは、前記消弧空間のうち最も広い空間から離れるにしたがって前記各消弧板の間隔が大きくなるように構成されることを特徴とする回路遮断器。 - 固定接点を備え、
前記消弧グリッドは、前記固定接点に近いほど前記各消弧板の間隔が大きくなるように構成されることを特徴とする請求項1記載の回路遮断器。 - 前記消弧装置を収納する器体を備え、
前記器体は、前記消弧空間と対向する位置にアークを外部に排気する排気孔を有し、
前記消弧グリッドは、前記消弧空間のうち排気孔と対向する空間から離れるにしたがって前記各消弧板の間隔が大きくなるように構成されることを特徴とする請求項1又は2記載の回路遮断器。
