RSVP-TE Extensions For Shared-Mesh Restoration in Transport Networks

A disconnecting switch for a force-cooled isolated phase bus comprises means for interrupting magnetizing currents when the switch is opened. The interrupting means comprises a vacuum-type circuit interrupter located in the space between the bus conductor and its surrounding enclosure. The bus conductor comprises a plurality of bus sections, one of which is movable to establish a gap in the bus conductor and to actuate a cam for controlling the vacuum interrupter. When the gap in the bus conductor is established, a shunting path extends through the closed vacuum interrupter until the cam allows the vacuum interrupter to open. The cam includes an auxiliary portion movable with respect to the rest of the cam for maintaining the continuity of the shunting path through the interrupter until the interrupter opens.
