Title: Stack of bus bars for a power distribution system.
Abstract: A power distribution system comprising a stack of bus bars having through-hole openings arranged in end portions of each of the bars such that the stack of the bars are connectable to bars of an adjacent stack. One or more connectors pass through the holes in one of the end portions of the bars of the stack. The one or more connectors also pass through holes in one of the end portions of the bars of the adjacent stack. One of the end portions of the bars of the stacks are interleaved with one of the end portions of the bars of the adjacent stack. ...

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application Ser. No. 61/308,215, filed on Feb. 25, 2010, to Edward C. Fontana, et al. entitled, “POWER DISTRIBUTION PLATFORM;” Provisional Application Ser. No. 61/287,322, filed on Dec. 17, 2009, to Roy Davis, et al. entitled, “HYBRID ARCHITECTURE FOR DC POWER PLANTS;” and Provisional Application Ser. No. 61/287,057, to filed on Dec. 16, 2009 to Edward C. Fontana, et al. entitled, “A FLOOR MOUNTED DC POWER DISTRIBUTION SYSTEM,” which are all commonly assigned with this application and incorporated herein by reference in their entirety.

TECHNICAL FIELD

This application is directed, in general, to a power distribution system and, more specifically, to a stack of DC power bus bars for a power distribution platform and method of installing the power distribution system having such a stack of bus bars.

BACKGROUND

This section introduces aspects that may be helpful to facilitating a better understanding of the inventions. Accordingly, the statements of this section are to be read in this light. The statements of this section are not to be understood as admissions about what is in the prior art or what is not in the prior art.

Telecommunication sites are evolving into large data centers, making extensive use of many similar configurations of server equipment. The Green Grid consortium has suggested that 48VDC is the most efficient and cost effective way to power such equipment, and, provide the highest availability and reliability of reserve power in case of utility grid failure. Present DC distribution and installation practices, however, can be time consuming, have high labor costs, and require large amounts of copper cabling with its associated overhead support structures, thereby further increasing the costs of such installations.

There is a long-felt need to more efficiently install and distribute DC power to server equipment at reduced labor and material costs.

SUMMARY

One embodiment provides a power distribution system. The system comprises a stack of bus bars having through-hole openings arranged in end portions of each of the bars such that the stack of the bars are connectable to bars of an adjacent stack. One or more connectors pass through the holes in one of the end portions of the bars of the stack. The one or more connectors also pass through holes in one of the end portions of the bars of the adjacent stack. One of the end portions of the bars of the stacks are interleaved with one of the end portions of the bars of the adjacent stack.

Another embodiment provides a method of assembling the above-described power distribution system. The method comprises positioning a first one of the bars of the stack in a target location of the system and positioning a first one of the bars of the adjacent stack such that a long axis end of the first bar of the stack contacts a long axis end of the first bar of the adjacent stack and the two first bars are coplanar. The method further comprises positioning a second one of the bars of the stack on the first bar of the stack such that at least one of the holes in the one end portion of the second bar of the stack aligns with at least one of the holes in the one end portion of the first bar of the adjacent stack. The method also comprises passing at least a first one of the connectors through the aligned holes in the second bar of the stack and in the first bar of the adjacent stack.
