Abstract | A portable, remote racking device that is controlled by a remote control. The remote racking device includes a drive that fits into a corresponding crank access hole formed in a front panel of a cradle housing a circuit breaker installed into a switchgear. The drive turns a mechanism inside the cradle that causes the circuit breaker to be racked into or out of the switchgear. The remote racking device includes an actuator pin that abuts a corresponding button arm protruding through the front panel. The remote control includes a control for depressing the button arm and another control for causing a motor to rotate the drive. The actuator pin detects when the button arm pops out of the panel, and a circuit in the remote racking device briefly reverses the motor to bring it and the circuit breaker to a sudden stop, preventing the mechanical linkages of the mechanism from locking-up or becoming damaged and avoiding over-torquing the motor.
Se describe un dispositivo de activación/desactivación remota, portátil, que se controla por un control remoto. El dispositivo de activación/desactivación remota incluye un impulsor que se ajusta en un agujero de acceso de manivela correspondiente formado en un panel frontal de un bastidor que aloja un cortacircuito instalado en un aparato de conmutación. El impulsor hace girar un mecanismo dentro del bastidor que provoca que el cortacircuito se acople o desacople del aparato de conmutación. El dispositivo de activación/desactivación remota incluye un perno accionador que colinda con un brazo de botón correspondiente que sobresale a través del panel frontal. El control remoto incluye un control para presionar el brazo de botón y otro control para provocar que un motor haga girar el impulsor. El perno actuador detecta cuando el brazo de botón salta del panel, y un circuito en el dispositivo de activación/desactivación remota invierte brevemente el motor para llevarlo al cortacircuito a una detención súbita, evitando que conexiones mecánicas del mecanismo se cierren o se dañen y evitando la sobretorsión del motor. |
