Apparatus for securing a conductor in a power switching device
View Patent ↗A power switching device for use in a power distribution network has a conductive element that is shaped in a non-cylindrical form. The non-cylindrical shape of the conductive element allows the non-conductive material such as epoxy that is used to form the body of the device to securely fasten the conductive element in place to thereby keep the conductive element from rotating when excessive rotational force is applied to the conductor. The conductive element can be shaped with a protrusion or in a C-shape. The protrusion and C-shape help prevent rotation of the conductive element when a threaded bolt is applied to secure a power cable to one end of the conductive element.
1. A power switching device for use in transmitting and distributing power, said power switching device comprising:
a vacuum interrupter;
a non-cylindrical conductor, one end of said non-cylindrical conductor for electrical connection to a power source, the other end of said non-cylindrical conductor electrically connected to said vacuum interrupter, said non-cylindrical conductor and vacuum interrupter encased in a non-conductive housing, and
wherein the non-cylindrical conductor is C shaped.
2. The power switching device of claim 1 wherein the non-cylindrical conductor further comprises a protrusion.
3. The power switching device of claim 1 wherein the non-cylindrical conductor comprises copper.
4. The power switching device of claim 1 wherein the non-cylindrical conductor comprises aluminum.
5. The power switching device of claim 1 wherein the power switching device is a recloser.
6. A conductor for use in a power switching device, said power switching device installed in a power distribution network, said conductor comprising:
a cylindrical portion having a central axis;
a base portion;
a protrusion, said protrusion connecting said cylindrical portion to said base portion, said protrusion being offset from said central axis; and
wherein a gap is formed along said central axis between said cylindrical portion and said base portion.
7. The conductor of claim 6 wherein said base portion is disk-shaped and centrally aligned with said central axis.
8. The conductor of claim 6 wherein said base portion, said protrusion and a portion of said cylindrical portion form a C-shape.
9. The conductor of claim 6 further comprising a threaded hole in said cylindrical portion.
10. The conductor of claim 6 further comprising a metallic coating applied to said conductor.
11. A power distribution network comprising:
a power source; and,
a power switching device, said power switching device comprising a conductor for connecting to said power source, said conductor having a cylindrical portion having a central axis, a base portion and a protrusion connecting said cylindrical portion to said base portion, wherein a gap is formed along at least a portion of said central axis between said cylindrical portion and said base portion, said base portion, said protrusion and a portion of said cylindrical portion forming a C-shape.
12. The power distribution network of claim 11 wherein the power switching device is a recloser.
13. The power distribution network of claim 11 wherein the power switching device is a breaker.
14. The power distribution network of claim 11 wherein the power switching device is a switch.
15. The power distribution network of claim 11 wherein the power source is a substation.
16. The power distribution network of claim 11 wherein the conductor further comprises a threaded hole in said cylindrical portion.
17. The power distribution network of claim 11 wherein the conductor is coated in a metallic coating.
18. The power distribution network of claim 11 wherein said base portion is disk-shaped and centrally aligned with said central axis.
