Abstract

A device connectable to an electric power line conductor including an electrically conductive insulated wire wound at least twice. A first end of the wire is configured to be connected to a first power line conductor and a second end of the wire is configured to be connected to a second power line conductor. A housing is mountable to the wire and includes an iron core power supply transformer configured to surround the wire to power a power supply module.

Claims

1. A device connectable to an electric power line conductor comprising:

an electrically conductive insulated wire wound at least twice around a loop tube having a first end and a second end, wherein the wire is configured to be connected in series with a power line conductor; and

a housing including a pair of jaws mountable to the loop tube including an iron core power supply transformer configured to surround the wire to power a power supply module.

2. The device of claim 1 wherein the loop tube is a hollow loop with a slot around a periphery, wherein the slot is configured to accept the wire.

3. The device of claim 2 wherein the slot forms a heat transfer fin configured to remove heat from wire.

4. The device of claim 1 wherein the wire passes through the iron core power supply at least as many times as the wire is wound.

5. The device of claim 1 wherein the wire is configured to multiply the current realized by the power supply transformer to provide higher secondary voltage and higher secondary current to power the device.

6. The device of claim 2 wherein the wire is configured to be mechanically attached to the power line conductor.

7. The device of claim 1 wherein the wire is wound at least three times.

8. The device of claim 1 including an electrically insulated bridge mounted between the first end of the wire and the second end of the wire to prevent forces on the wire created by excessive power line fault current from pushing the wires apart.

9. The device of claim 2 including a first anchor rod electrically isolated from a second anchor rod.

10. The device of claim 9 wherein the first anchor rod is configured to attach to the power line conductor and a anchor rod is configured to attach to the power line conductor and a shorting bar electrically connecting the first anchor rod and the second anchor rod for electrically bypassing the wire.

11. The device of claim 9 including an electrically insulating spacer rod located between a first anchor rod and a second anchor rod, the spacer rod supports the wire and the housing and is configured to provide an electrically conductive path between the power line conductor and for providing tension in the power line conductor.

12. The device of claim 9 including at least one of an automatic dead end or a link attached to a first hole in the first anchor rod and secured with a retention pin.

13. The device of claim 12 including at least one of an automatic dead end or a link attached to a first hole in the second anchor rod and secured with a retention pin.

14. The device of claim 9 including a first hole in the first anchor rod and a second hole in the second anchor rod, wherein the first hole is configured to accept a first end cap on a first insulated post and the second hole is configured to accept a second end cap on a second insulated post.

15. The device of claim 9 including a first hole in the first anchor rod and a second hole in the second anchor rod, wherein the first hole is configured to accept a first link attached to a first suspension insulator and the second hole is configured to accept a second link attached to a second suspension insulator.

26. The device of claim 1 including a shorting bar for electrically bypassing the wire.

16. A device connectable to an electric power line conductor comprising:

a loop tube providing a form;

at least two turns of electrically conductive and insulated wire surrounding the loop tube configured to be connected in series with an electric power line conductor;

a housing mountable to the wire including an iron core power supply transformer configured to surround the wire to power a power supply module; and

a shorting bar for electrically bypassing the wire.

17. The device of claim 16 including a slot on a periphery of the loop tube for accepting the wire.

24. The device of claim 16 including a bracket configured to be mounted to a pole having at least one cantilevered insulator engaging the device and configured to be attached to a pole.

25. The device of claim 24 wherein the at least one cantilevered insulator engages a hole in an anchor rod.

18. A device connectable to an electric power line conductor comprising:

a loop tube providing a form including a slot for accepting a first locking device, the first locking device including a projection on one end that has a width approximately equal to a slot width and a depth approximately equal to a wall thickness of the loop tube;

at least two turns of electrically conductive and insulated wire surrounding the loop tube configured to be connected in series with a electric power line conductor; and

a “

U”

shaped first band for holding the projection into the slot and preventing the loop tube from rotating with respect to the wire located within the loop tube.

19. The device of claim 18 including a first band having a first end adjacent the projection holding the loop tube to the first locking device and a second end affixed to the other end of the first locking device.

20. The device of claim 19 wherein the loop tube, the first locking device, and the first band are affixed to a member, the member is configured to be connected to the first power line conductor.

21. The device of claim 20 including a second locking device spaced from the first locking device and a second band spaced from the first band for supporting the loop tube and the wire.

22. The device of claim 21 wherein the first locking device is attached to a first member and the first member is configured to be attached to the power line conductor and the second locking device is attached to a second member and the second member is configured to be attached to the power line conductor.

23. The device of claim 22 including a first connector attached to a first end of the wire and a second connector attached to a second end of the wire.
