Claims

[Scope of utility model registration request]

(1) A contact consisting of a cylindrical contact that uses insulating gas as an arc-extinguishing medium and has a deep redundancy as a contact part and is covered with a cylindrical shield supported on its pedestal, and a rod-shaped contact that can be brought into contact with and separated from the cylindrical contact. In a shaft-acting type gas disconnector equipped with a slave device, an arc generated when the switch is opened, which is provided on the opposite side of the rod-shaped contact in the cylindrical shield and is arranged at right angles to the axis and spaced apart. U with one V-shaped groove that serves as a current flow path
It consists of a plurality of grid plates made of ferromagnetic material in the shape of letters, and an insulator that supports the grid plates and has a hot gas flow path that communicates with each of the gaps and is parallel to the flow path of the arc current. A gas disconnector characterized by having an arc extinguishing chamber.

(2) Utility Model Registration The gas disconnector according to claim 1, characterized in that the pedestal is provided with a gas passage hole penetrating the back thereof.

(3) Utility Model Registration The gas disconnector according to claim 2, characterized in that a lid body having pores facing in a predetermined direction is provided on the outside of the gas passage.
