Abstract
A foreign matters trap in which a metallic corrugated plate is arranged in a ground tank so that a line connecting portions of the corrugated plate having the same height is made parallel to a central axis of the ground tank, a metallic round rod is mounted to an corrugated end of the corrugated plate, the corrugated plate and the metallic round rod are connected electrically to each other, and a surface of the corrugated plate is covered by an insulating material. The foreign matters trap is capable of surely trapping metallic foreign matters in a gas insulated electric apparatus and suppressing concentration of an electric field to become excellent in voltage endurance and which can be readily mounted in a ground tank.
