Abstract (en)
[origin: US4659886A] A disconnect switch, suitable for various conductor runs within a section of a metal-clad, gas-filled, high-voltage switchgear, with shielding bodies enclosing the ends of the conductors, is operated through a rotating insulator shaft that is perpendicular to the plane of the phase-current path of the section. One shielding body is made approximately in the shape of a sphere, whose center lies on the axis of the rotating insulator shaft and on the longitudinal axis of a movable switch contact. In the interior of the sphere there are one or more surfaces to accept a connecting means necessary for connection with the end of a first conductor. The mid-perpendiculars of each of the connection surfaces lie in the plane of the phase-current path. The isolating gap also lies in the path of an angled second conductor.
