摘要

Improvements in the arrangement of switches for the extinction of the arc caused by the electric discharge, characterized in that the breaker valve is constituted by: a covering of insulating material and resistant to atmospheric agents, which houses a housing of also insulating material, inside which it is in turn placed a cylinder of the same material, and that fits tightly in said casing; so that the juxtaposed surfaces leave a gap between them, so that the arc is formed when the valve operates, whose casing is surrounded by a band connected to earth, of a length greater than said cylinder.
