Abstract:
Power operator apparatus for switchgear having a switchgear operating shaft comprising:power drive means responsive to an energy source for providing a power-driven output;a manual drive input;an operator output adapted to be coupled to the switchgear operating shaft; anddrive coupling means coupled to said power-driven output and said manual drive input for coupling movement of said power-driven output and said manual drive input to said operator output, said drive coupling means comprising means for selectively coupling said power-driven output to move said operator output after predetermined movement of said power-driven output, said drive coupling means comprising a driven lever that is coupled to said operator output and that comprises first and second spaced apart driven surfaces, said drive coupling means further including a drive lever coupled to said power-driven output and including first and second spaced apart actuating portions that interact respectively with said first and second spaced apart driven surfaces via movement of said drive lever so as to contact and drive said first and second spaced apart driven surfaces.
