Abstract

A bridge joint cover assembly for a busway bridge joint, the assembly comprising a bridge joint cover plate having a cover plate hole, a viewing plate fixed to the cover plate, over the cover plate hole, and the viewing plate including infrared (IR) material. The IR material is further aligned with the cover plate hole in the bridge joint cover plate.

First claim

What is claimed is:

1. A bridge joint cover assembly comprising:
a bridge joint cover plate configured to extend between a pair of busways and to cover a bridge joint, wherein the bridge joint cover plate includes a cover plate hole; and
a viewing plate fixed to the bridge joint cover plate, wherein the viewing plate covers the cover plate hole; and
infrared (IR) material located on the viewing plate, wherein the IR material has physical properties suitable for obtaining a temperature reading therethrough, and wherein the IR material is aligned with the cover plate hole in the bridge joint cover plate.

2. The bridge joint cover assembly of claim 1 , wherein the IR material includes at least one port.

3. The bridge joint cover assembly of claim 2 , wherein the at least one port is a plurality of honeycomb-shaped ports.

4. The bridge joint cover assembly of claim 1 , wherein the viewing plate further includes a cover connected to the viewing plate.

5. The bridge joint cover assembly of claim 4 , further comprising a fastening assembly at an upper portion of the bridge joint cover plate, wherein the fastening assembly is configured to selectively lock the upper portion of the bridge joint cover plate to the viewing plate.

6. The bridge joint cover assembly of claim 1 , wherein the viewing plate is connected to the bridge joint cover plate via one or more bolts.

7. The bridge joint cover assembly of claim 1 , wherein the viewing plate is connected to the bridge joint cover plate via welding.

8. The bridge joint cover assembly of claim 1 , wherein the bridge joint cover plate includes two horizontally extending flanges to fix the bridge joint cover plate to at least one busway.

9. The bridge joint cover assembly of claim 1 , further including a top plate and a bottom plate that attach to the bridge joint cover plate, to cover a top and a bottom of a bridge joint.

10. The bridge joint cover assembly of claim 1 , wherein the bridge joint cover plate further includes at least one elongated hole configured to receive a bolt.

11. A method for reading temperatures at a bridge joint extending between a pair of busways, comprising the steps of:
opening an infrared (IR) material cover on a viewing plate of a bridge joint cover plate to expose IR material of the viewing plate, wherein the IR material has physical properties suitable for obtaining a temperature reading therethrough, and wherein at least a portion of a bridge joint is visible through the IR material of the viewing plate; and
measuring a temperature on at least a portion of the bridge joint, while the busway is live.

12. The method for reading temperatures at a bridge joint of a busway of claim 11 , wherein the step of measuring is performed with a non-contact temperature gun.

13. The method for reading temperatures at a bridge joint of a busway of claim 11 , wherein the measuring is done through the IR material of the viewing plate.

14. The method for reading temperatures at a bridge joint of a busway of claim 11 , wherein the IR material cover is attached to the viewing plate.

15. The method for reading temperatures at a bridge joint of a busway of claim 11 , wherein the IR material comprises a plurality of honeycomb-shaped ports.

16. A bridge joint cover assembly comprising:
a bridge joint cover plate configured to extend between a pair of busways and to cover a bridge joint, wherein the bridge joint cover plate includes a cover plate hole;
a viewing plate fixed to the bridge joint cover plate and covering the cover plate hole, wherein at least a portion of the viewing plate is constructed of infrared (IR) material, wherein the IR material has physical properties suitable for obtaining a temperature reading therethrough; and
a cover connected to the viewing plate.

17. The bridge joint cover assembly of claim 16 , wherein the cover is hingedly connected to the viewing plate.

18. The bridge joint cover assembly of claim 16 , wherein the viewing plate includes a plurality of ports constructed of IR material, and wherein the plurality of ports are separated by sections of non-IR material.

19. The bridge joint cover assembly of claim 16 , wherein the bridge joint cover plate includes a pair of flanges.

20. The bridge joint cover assembly of claim 16 , further comprising a back piece having a pair of flanges.
