One of Kutin's latest inventions is the DC vacuum relay device with an angular impact break mechanism. This innovative relay device utilizes an angular 'impact break' method to achieve contact break. A rotatable armature is pivotally mounted to one end of the relay while its other end remains separated from the relay pole center by a spring. A separate rotatable actuator, carrying a moving contact, is movably positioned atop the armature and pivoted at the same point where the armature is pivotally mounted. The armature responds to the electromagnetic effects caused by the excitation of the coil and rotates downward towards the pole center. The actuator rotates along with the armature, due to a spring receptacle on the armature and an overtravel spring between the receptacle and actuator, until the moving contact connected to the actuator contacts the stationary contacts of the relay. After contact, the armature continues its rotation while the actuator maintains the contact between the moving and stationary contacts. Upon de-energization, the armature rotates upward and away from the pole center and, before making contact with the actuator, acquires kinetic energy which is imparted upon the actuator upon impact with the same. The impact force is sufficient to break the previously closed contacts and any welding that occurs between the contacts. The relay device further provides a number of features serving to reduce arcing, puddling, and welding. Another significant invention is the sealed relay device, which is of the high-vacuum type or may be backfilled with a dielectric gas such as a hydrogen-nitrogen mixture for improved arc suppression when switching high-voltage d-c currents. This relay uses controlled fixed contacts that enable the use of a reduced-diameter disk-shaped movable contact, allowing optimal placement of external arc-supporting permanent magnets on a ceramic relay housing in close proximity to the enclosed fixed and movable contacts. A staggered or offset positioning of the fixed contacts makes the relay polarity insensitive for bidirectional switching of high-voltage d-c currents.
