Abstract
An interrupted electric circuit recloser for reclosing an interrupted high voltage electric circuit system and a solenoid to be utilized for use in a sealed pressurized dielectric gaseous atmosphere. The recloser has a sealed tank and a solenoid therein. The solenoid has a plunger connected through a yoke for returning vacuum contact back to a closed contacting position, a dampener for regulating the opening movement of the plunger, a dielectric gas filling the sealed chamber and permeating the solenoid and acted on by the solenoid plunger. The solenoid also has a central chamber complimentarily accepting the plunger. The central chamber of the solenoid is substantially closed at one end and permits the ingress of the dielectric gas when the plunger is moved in an outward direction within the central chamber away from the closed end and a second dampener controlling the solenoid plunger's movement toward the closed end.
