Claims
- 1. A switchgear conductor for engagement by a quick disconnect, said switchgear conductor comprising:
- a stacked pair of elongated flat members having first ends for engagement by said quick disconnect and at least one set of aligned, through apertures adjacent said first ends of said elongated flat members with recesses around each aperture at outer surfaces of said elongated flat members, and at least one fastener extending through said at least one set of aligned through apertures and having enlarged ends fully seated in said recesses.
- 2. The switchgear conductor of claim 1 wherein said recesses around each aperture at said outer surfaces of said elongated flat members are beveled countersinks.
- 3. The switchgear conductor of claim 2 wherein said fastener comprises an electrically conductive slug longer than a combined thickness of said pair of elongated flat members which is compressed into said countersinks.
- 4. The switchgear conductor of claim 1 wherein said fastener comprises an electrically conductive slug longer than a combined thickness of said pair of elongated flat members which is compressed into said recesses.
- 5. A switchgear assembly comprising:
- a cabinet;
- at least one electrical apparatus removably mounted in said cabinet and having a set of quick disconnects projecting from a face thereof;
- conductor supports including a first support extending across and spaced from said set of quick disconnects and having a set of through openings aligned with said set of quick disconnects; and
- a plurality of buses mounted in said cabinet and including interface conductors having first ends inserted through and supported in said through openings in said first support in position for engagement by said set of quick disconnects, each of said interface conductors comprising a stacked pair of elongated flat members having at least one set of aligned countersunk through apertures adjacent said first end, and a fastener with enlarged ends extending through and fully seated within said at least one set of aligned, countersunk through apertures clamping said free ends of said pair of elongated flat members together.
- 6. The switchgear assembly of claim 5 wherein said interface conductors extend generally horizontally within said cabinet and said plurality of buses include a set of risers extending vertically in said cabinet adjacent said first support and spaced by said first support from said quick disconnects, and wherein said conductor supports include a second support spaced horizontally from said risers remotely from said first support, some of said interface conductors are stabs connected to said risers and others of said interface conductors are runbacks extending between said risers and through said second support.
- 7. The switchgear assembly of claim 6 wherein said stabs have second ends of said pair of elongated flat members straddling and connected to said risers.
- 8. The switchgear assembly of claim 6 wherein said conductor supports further include phase-to-phase supports connected between said runbacks between said risers and said second support.
- 9. The switchgear assembly of claim 8 wherein said phase-to-phase supports comprise a spacer extending between adjacent of said runbacks, flanges on each end of said spacers bearing against said runbacks and fasteners securing said runbacks to said flanges.
- 10. The switchgear assembly of claim 9 wherein said phase-to-phase supports have opposed flanges extending laterally at each end of said spacer.
- 11. The switchgear assembly of claim 9 wherein said phase-to-phase supports comprise C-channel members having a web forming said spacer with said flanges extending along ends of said web.
- 12. The switchgear assembly of claim 6 wherein said runbacks include conductors having second ends of said elongated flat members adjacent said second support which are offset laterally by transverse sections with said pair of elongated flat members being spaced apart in said transverse section but abutting in said second ends which have aligned through apertures.
- 13. The switchgear assembly of claim 5 wherein said first support comprises a base member having said through openings and the rigid extensions projecting from said base member toward said quick disconnects along side said through openings and terminating in free ends, and fastener means securing said conductors to said rigid extensions adjacent said free ends.
- 14. The switchgear assembly of claim 13 wherein said rigid extensions have a planar surface aligned with an edge of said through opening and against which said conductor is secured by said fastener means.
