Claims

[Claims for Utility Model Registration] Arc runner electrodes are provided on top of each of the fixed electrode and the movable electrode, facing each other in parallel, sandwiching these arc runner electrodes, and the area close to the two electrodes is wide, a pair of arc extinguishing plates forming a slit that gradually narrows toward the upper end of the arc runner electrode, the slit formed by the arc runner electrode on one side and the upper end of the arc extinguishing plate serving as a discharge port; In an arc extinguishing chamber of a current limiting device having a hexahedral pressurizing chamber which seals and covers the fixed electrode, movable electrode, arc runner electrode and arc extinguishing plate on five sides with an insulating container, the arc extinguishing chamber is interlocked with the movable electrode. 1. A current limiting device comprising: an electromagnetic repulsion device including a coil and a repulsion plate; and a structure in which gas is released into the pressurization chamber by the repulsion plate and cylinder.
