Abstract

A compact busway system for low and medium voltage application is described. In particular, the described compact busway system is designed for low and medium power distribution systems for high current applications. The described compact busway system has a enclosure assembly with at least two side mount supports affixed to the enclosure assembly and at least two horizontal supports, a first horizontal support and a second horizontal support, which are connected and perpendicular to the at least two side mount supports. The compact busway system further includes at least one busbar affixed between the first horizontal support and the second horizontal support, at least one strap connected to the first horizontal support and the second horizontal support, and at least one ground bus connected to the enclosure assembly.

First claim

What is claimed is:

1. A compact busway arrangement comprising:
an enclosure assembly;
at least two side mount supports affixed to the enclosure assembly;
at least two horizontal supports, including at least a first horizontal support and a second horizontal support, connected and perpendicular to the at least two side mount supports;
at least one busbar affixed to and extending between the first horizontal support and the second horizontal support;
at least one strap connected to the first horizontal support and the second horizontal support; and
at least one ground bus connected to the enclosure assembly.

2. The compact busway arrangement of claim 1 further including:
at least one insulating boot, wherein the at least one insulating boot encapsulates an end point of the at least one busbar and sides of the at least one insulating boot are secured together;
at least one splice plate, wherein the at least one splice plate connects to the end point of the at least one busbar; and
at least one joint cover, connected to the end point of the at least one busbar to secure two or more compact busway arrangement sections together.

3. The compact busway arrangement of claim 2 , wherein the at least one splice plate connects the at least one busbar to a second busbar of the two or more compact busway arrangement sections.

4. The compact busway arrangement of claim 1 , wherein the at least one busbar has a two story busbar layout, the two-story busbar layout including:
four busbars arranged in pairs on the at least two horizontal supports.

5. The compact busway arrangement of claim 1 , wherein a phase conductor is included in the enclosure assembly without a phase barrier.

6. The compact busway arrangement of claim 1 further including a collar connection to secure two or more compact busway arrangement sections together.

7. The compact busway arrangement of claim 1 , wherein the at least one busbar is arranged in an interleaved configuration.

8. The compact busway arrangement of claim 1 , wherein the at least one busbar is a copper busbar and is arranged in a non-interleaved configuration.

9. The compact busway arrangement of claim 1 , wherein the compact busway arrangement is one of a straight configuration, elbow configuration, T configuration, or flange configuration.

10. The compact busway arrangement of claim 1 , wherein the at least two horizontal supports are one of glass polyester GPO-3, or epoxy or porcelain standoff insulators with GPO-3 supports.

11. A compact busway system comprising:
an enclosure housing assembly;
at least two enclosure housing assembly side supports connected to the enclosure housing assembly;
at least two or more horizontal supports, including at least a first horizontal support and a second horizontal support, connected perpendicular to the at least two enclosure housing assembly side supports, wherein the first horizontal support is connected parallel to the second horizontal support;
at least one or more busbars, the at least one or more busbars connected perpendicular to the first horizontal support and second horizontal support;
at least one strap connected to the first horizontal support and the second horizontal support;
at least one ground plate connected to the enclosure housing assembly;
at least one splice plate, the at least one splice plate connected to a busbar joint of the at least one or more busbars;
at least one insulating boot covering the busbar joint; and
at least one joint cover connected to the end point of the at least one or more busbars to secure multiple compact busway arrangement sections together.

12. The compact busway system of claim 11 , wherein the at least one or more busbars are uninsulated for use in a 600V application.

13. The compact busway system of claim 11 , wherein the at least one or more busbars are insulated for a 5 or 15 KV application.

14. The compact busway system of claim 11 , wherein the at least one or more busbars are interleaved in a two-story configuration.

15. The compact busway system of claim 11 , wherein the at least one or more busbars are non-interleaved in a two-story configuration.

16. The compact busway system of claim 11 further including a coupling plate configured to connect at a termination joint.

17. The compact busway system of claim 11 , wherein the at least two or more horizontal supports are configured to have one of a length stagger support arrangement or a height stagger support arrangement.

18. The compact busway system of claim 11 , wherein
the at least one splice plate includes at least four splice plates encapsulating the at least one or more busbars, the at least one or more busbars are not in connection with one another.

19. A compact busway system comprising:
a continuous enclosure housing configured to meet dimensions for a compact design application for use in indoor or outdoor applications;
at least two side supports configured to fit within the continuous enclosure housing and attached to the continuous enclosure housing;
at least four horizontal supports, including a first horizontal support adjacent to a second horizontal support, and a third horizontal support adjacent the second horizontal support and a fourth horizontal support, the at least four horizontal supports connected to the at least two side supports;
at least four straps bolted at opposite ends of the at least four horizontal side supports, configured to support and exert a clamp force on the at least four horizontal supports;
at least one busbar, wherein the at least one busbar includes a coating for insulation and a plating, the at least one busbar clamped to the first horizontal support and the second horizontal support; and
at least one ground bar connected to the continuous enclosure housing.
