具備してなることを特徴とするアレスタ装置。 a pair of main electrodes airtightly attached to openings at both ends of the insulating tube, a ground electrode attached to the center of the insulating tube, each connected to the pair of main electrodes, and connected to the insulating tube. a pair of main electrode terminals extending in a direction perpendicular to the axis of the body; a ground electrode terminal connected to the ground electrode and extending parallel to the pair of main electrode terminals; It has a substantially U-shaped shape that is bent and extends to the pair of electrode terminals, the center portion of which is electrically connected to the ground electrode terminal,
Both ends are opposed to the pair of main electrode terminals by a spring action through a spacer made of a low melting point insulating material, and when the arrester overheats, the spacer is melted and the both ends and the pair of main electrode terminals are connected. An arrester device comprising a conductive short-circuiting element made of a spring material, which electrically connects the two main electrodes to each other by the spring action, thereby short-circuiting the pair of main electrodes and the ground electrode, respectively.
