摘要： A current limiting apparatus includes at least two pairs of generally parallel conductive rails each having an initial high conductivity portion and a more resistive portion. A sliding armature conductor is positioned between each pair of rails and makes sliding electrical contact with the rails such that a high fault current flowing through the rails and the associated armature conductor produces forces which propel the armature conductor along the rails thereby increasing the resistance through which current flows. The pairs of rails are geometrically associated such that current flowing in each pair of rails augments the accelerating force on the armature conductor located between the other pair of rails. Additional accelerating force augmenting may be provided by a multiple turn coil located near the high conductivity portions of the rails.

摘要： Rotating shaft carries contact arms which are stressed into the switch closed position where they are in contact with two stationary contact fingers by the torque of a stressed torsion bar. An electrodynamic drive motor additionally stressed the torsion bar to rotate the contacts on the contact shaft away from the stationary contact fingers. The contacts are held in the open position by a one-way clutch and disc brake. Release of the disc brake permits the torsion bar to return the rotating contact shaft bar to the switch closed position.

摘要： Automatic transfer switches and methods of forming such switches are disclosed herein. One automatic transfer switch disclosed herein includes a first source bar structured to connect to a first power source, a second source bar structured to connect to a second power source, and a stationary bar structured to be coupled to a load. The automatic transfer switch also includes a first movable bar and a second movable bar each electrically coupled and rotatably connected to the stationary bar. The length of each movable bar and the angle of each movable bar with respect to the stationary bus bar are selected to approximately balance the contact force on each movable bar. Thus, smooth and reliable operations of the automatic transfer switch can be achieved.

摘要： A fault interrupter and load break switch includes a trip assembly configured to automatically open a transformer circuit electrically coupled to stationary contacts of the switch upon the occurrence of a fault condition. The fault condition causes a Curie metal element electrically coupled to at least one of the stationary contacts to release a magnetic latch. The release causes a trip rotor of the trip assembly to rotate a rotor assembly. This rotation causes ends of a movable contact of the rotor assembly to electrically disengage the stationary contacts, thereby opening the circuit. The switch also includes a handle for manually opening and closing the electrical circuit in fault and non-fault conditions. Actuation of the handle coupled to the rotor assembly via a spring-loaded rotor causes the movable contact ends to selectively engage or disengage the stationary contacts.
