CONTACT SYSTEM (ALTERNATIVES) Russian patent published in 2002 - IPC

FIELD: electrical engineering; high-voltage disconnecting switches. SUBSTANCE: novelty introduced in known contact system that has current conductor, contact member, holder, contact blade stop, contact blade, and paired segments embracing contact member during ON-operation is that mentioned segments are secured to contact blade, each pair of segments being disposed in plane perpendicular to plane of contact blade turning and that contact member is hinged to current conductor by means of holder for turning together with holder in plane of contact blade turn under action of contact blade pressure onto stop; holder is provided in addition with extreme position stops and flexible member that functions to facilitate OFF-operation. As an alternative contact member may be secured to contact blade and segments may be hinged to current conductor by means of holder. EFFECT: enhanced uniformity of segments pressure on contact member; reduced shaft torque of operating mechanism. 2 cl, 6 dwg
