description PURPOSE:To increase an arc voltage and improve a breaking performance. CONSTITUTION:A sealed contact apparatus comprises a sealed vessel 30 in which an electrical insulating gas is sealed into the inside and a hermetic space is formed, fixed contact points 32a and 33a secured in the sealed vessel 30, fixed contacts 32 and 33 connected to electrodes 2b and 3b, and a moving contact 35 having moving contact points 35a and 35b which is supported in the sealed vessel 30 by a moving rod 21 and is connected or disconnected to each fixed contact point 32a and 33a of the fixed contacts 32 aNd 33. Further, by installing grids 36 and 37 for extinction of arc in the proximity of the moving contact points 35a and 35b and the fixed contact points 32a and 33a, since an arc occurring between the moving contact points 35a and 35b and the fixed contact points 32a and 33a is drawn in and is divided, extension and cooling properties of the arc are improved and a high arc voltage can be generated. Thus, a long-term stable switching operation can be implemented.
