Abstract
A shaft grounding apparatus including a grounding rope in electrical contact with ground, and an adjustable rope guide configured to guide the grounding rope on an electrically conductive surface of a rotating shaft of an electric machine. The adjustable rope guide includes a plurality of articulating segments configured to provide the adjustable rope guide with a variable radius of curvature to closely follow a radius of curvature of the rotating shaft.
Claims20
A grounding rope guide for guiding a grounding rope on an electric machine, the grounding rope guide comprising:
- a first segment;
- a second segment, wherein the second segment is adjustably coupled to the first segment such that a radius of curvature of the adjustably coupled first segment and second segment is adjustable to align with a radius of curvature of a rotating shaft of the electric machine;
- wherein the first segment and the second segment are adjustably coupled to guide the grounding rope on an electrically conductive surface of the rotating shaft.
A grounding rope guide for guiding a grounding rope on an electric machine, the grounding rope guide comprising:
- a first channel configured to receive a grounding rope;
- a first segment;
- a second segment, wherein the second segment is adjustably coupled to the first segment to form a radius of curvature that is adjustable to align with a radius of curvature of a rotating shaft of the electric machine;
- wherein a radius of curvature of the first channel is adjustable to guide a grounding rope on an electrically conductive surface of the rotating shaft.
A grounding apparatus for grounding a rotating shaft of an electric machine, the grounding apparatus comprising:
- a mounting fixture;
- a grounding rope guide extending from the mounting fixture, the grounding rope guide comprising:
- a plurality of guide segments, each of two or more guide segments are adjustably coupled to an adjacent guide segment;
- one or more channels adapted to receive a grounding rope while the grounding rope maintains electrical contact along at least a partial circumference of the rotating shaft having a radius of curvature.
