ABSTRACT:
An automatic resetting subcircuit is disclosed in a remotely actuated power distribution switch control circuit characterized by a two-position electromechanical control for an automatic actuation mechanism for operating the switch. The control is provided with two elements, each for moving the control in an opposite direction between the open and closed positions of the switch. The circuit includes a first energy storage capacitor for storing energy received from a source remote from the circuit. A first thyristor, when triggered by a locally generated control signal, applies the energy stored in the first energy storage capacitor to one of the elements to cause the switch to be operated in a predetermined direction. The automatic resetting subcircuit includes a second energy storage capacitor for storing energy received from the remote source with the second energy storage capacitor being electrically isolated from the first thyristor. A sensor switch responds to the position of the distribution switch and is connected to reverse the connections of the first and second energy storage capacitors in accordance with the position of the power distribution switch. A time delay circuit is provided in conjunction with a second thyristor which is connected to the second energy storage capacitor and to the sensor switch. The gate of the thyristor is connected to the time delay circuit and to a transistor base controlled by the voltage on the first energy storage capacitor. If the voltage thereon goes to zero, indicating a signal switch, and the power distribution switch does not operate, the second thyristor passes the energy stored in the second energy storage capacitor to the other element of the electromechanical control to return the control to its initial position.
