摘要： A presently-preferred capacitor discharge system for a circuit breaker adapted for use in a switchgear enclosure comprises a capacitor discharge circuit adapted to be electrically coupled to the capacitor, and a contact switch electrically coupled to the capacitor discharge circuit and adapted to be mechanically coupled to a support truck of the circuit breaker. The contact switch is movable between a first and a second position. The system also comprises a resistor electrically coupled to the capacitor discharge circuit, and a lever arm adapted to be rigidly coupled to a racking mechanism of the circuit breaker and adapted to urge the contact switch into the closed position when a locking arm of the racking mechanism disengages from the switchgear enclosure. The capacitor discharge system is adapted to electrically couple the capacitor and the resistor when the contact switch is in the second position thereby discharging the capacitor.

摘要： Switch operator having an actuator, a drive mechanism coupled to the switch for actuating a switch in response to a rotational force applied to the drive mechanism, and a flexible shaft which couples the actuator to the drive mechanism and communicates the rotational motion of the actuator to the drive mechanism. An interlock mechanism prevents the actuation of a second switch as a function of a first switch and prevents the opening of a door as a function of the position of the first switch.
