Electrical circuit breaker with manual and remote actuators

摘要

An electricity switching device (10) has an control handle (16) reciprocally moveable between two positions. A remotely controllable operator (12) attaches to the switching device (12) and has an actuator (44) that is coupled by a lever (34) to the control handle (16) enabling for manual operation of the device. A motor (32) drives a threaded shaft (58) on which a driver (60) in mounted. Rotation of the threaded shaft (58) by the motor (32) causes the driver (60) to slide within the operator. A handle actuator (64) is coupled to slide with the driver (60) and pushes the control handle (16) between the two positions. Once the handle actuator (64) has been pushed into one of the two positions, the handle actuator moves over the other side of the control handle (16) in order to push in the opposite direction. Movement to the other side also eliminates the handle actuator (64) from interfering with manual operation of the electricity switching device (10). <IMAGE>
