Abstract

A busway system enables multiple interchangeable power support redundancies to be provided to electrical loads. The busway system includes multiple busways extending through an aisle space, where some busways carry power from separate primary power sources, and one or more busways carry power from a secondary power source. Busways are coupled to loads to provide power support directly to the loads, indirectly via devices that distribute power to the loads via branch circuits, etc. The power support redundancy provided to a load is established based at least in part upon which busways are coupled to the load, and power support redundancies can be changed by changing the couplings of particular busways with the loads. The busways can extend through the aisle space in a staggered configuration to enable load balancing between busways by restricting loads in certain regions of the aisle space to coupling with certain busways and not others.

First claim

1 .- 20 . (canceled)

21 . A data center, comprising:
a plurality of rack computer systems in aisles; a physical arrangement of power busways in one or more of the aisles, the physical arrangement of the power busways comprising:
at least two primary power busways that extend in a staggered configuration through a portion of an aisle space of an aisle of the one or more aisles, and
at least one secondary power busway that extends through the portion of the aisle space;
wherein the staggered configuration of the at least two primary power busways physically restricts coupling of one or more of the plurality of rack computer systems in the aisle to one or more busways in the aisle.

22 . The data center of claim 21 , wherein each of the at least two primary power busways and the at least one secondary power busway extend at least partially through an elevated portion of the aisle space.

23 . The data center of claim 21 , wherein:
to extend in a staggered configuration, each of the at least two primary power busways extend at least partially through a common region of the aisle space; and the at least two primary power busways are configured to electrically couple, via separate power cables, to another proximate rack computer system located in the common region to provide power support redundancy to the other proximate rack computer system.

24 . The data center of claim 21 , wherein the at least one secondary power busway and a particular one of the primary power busways that extend through the portion of the aisle space are configured to electrically couple, via separate power cables, to a proximate rack computer system located in the portion of the aisle space to provide a power support redundancy to the proximate rack computer system.

25 . The data center of claim 24 , further comprising a switching assembly for routing power;
wherein to electrically couple, via separate power cables, to the proximate rack computer system, the secondary power busway and particular primary power busway are configured to couple with a switching device assembly, via the separate power cables, where the switching assembly selectively routes power from one of the secondary power busway and particular primary power busway to the proximate rack computer system via a branch circuit.

26 . The data center of claim 25 , wherein the secondary power busway and primary power busways are configured to change the power support redundancy provided to the proximate rack computer system, wherein, to change the power support redundancy provided to the proximate rack computer system, the particular primary power busway is decoupled from the switch device assembly via a particular power cable, and another primary power busway is coupled to the switch device assembly via the particular power cable while maintaining distribution of power to one or more of the rack computer systems via at least one other of the power cables and the branch circuit.

27 . The data center of claim 21 , wherein:
each of the at least two primary power busways is configured to provide exclusive primary power support to electrical loads located in a respective region through which the respective primary power busway extends independently of other primary power busways; and the at least one secondary power busway is configured to provide secondary power support to electrical loads that are located in separate respective regions of the aisle space and receive primary power support from separate primary power busways extending exclusively through the separate respective regions.

28 . A system, comprising:
a plurality of power busways configured to extend through one or more regions of an aisle space, each region spanning a full width and a separate limited portion of a length of the aisle space; and a plurality of power cables configured to electrically couple the power busways to electrical loads located in the aisle space, wherein a length of the power cables restricts each of the electrical loads from being coupled to a busway that does not extend through a respective region of the aisle space.

29 . The system of claim 28 , wherein:
the plurality of power busways are configured to extend in a staggered configuration through the aisle space, and at least one of the plurality of power busways that are configured to extend in a staggered configuration is configured to:
extend less than a full length of the aisle space and
extend through a particular region of the aisle space that is free of at least one other of the plurality of power busways.

30 . The system of claim 29 , wherein:
to extend in a staggered configuration, the plurality of power busways are configured to extend at least partially through a common region of the aisle space, the plurality of power busways are configured to interchangeably provide at least one of a plurality of power support redundancies to at least one electrical load located in the aisle space, and to interchangeably provide at least one of a plurality of power support redundancies to at least one electrical load located in the aisle space, the plurality of power busways are configured to provide power support redundancy to an electrical load in the common region of the aisle space.

31 . The system of claim 30 , wherein:
the common region of the aisle space extends through a central region of the aisle space; and each of the plurality of power busways extend at least partially, and independent of each other, through separate particular regions of the aisle space extending away from the central region of the aisle space towards opposite ends of the aisle space.

32 . The system of claim 31 , wherein:
at least one of the plurality of power busways comprises a secondary power busway configured to distribute power from at least one secondary power source; each of the remaining power busways that is not the secondary power busway is configured to provide exclusive power support to electrical loads located in a respective region through which the respective power busway extends independently of other power busways; and the secondary power busway is configured to provide secondary power support to electrical loads that are located in separate respective regions of the aisle space and receive power support from separate power busways extending exclusively through the separate respective regions.

33 . The system of claim 30 , wherein, to interchangeably provide power support redundancy to an electrical load in the common region of the aisle space, the plurality of power busways are configured to:
electrically couple with a particular rack computer system, via respective tap boxes coupled to each of the plurality of power busways; and electrically decouple from the particular rack computer system, via the respective tap boxes.

34 . The system of claim 30 , comprising separate tap boxes;
wherein to interchangeably provide at least one of a plurality of power support redundancies to at least one electrical load located in the aisle space, each of the plurality of power busways are configured to electrically couple with one or more electrical loads via separate power cables that are each coupled to a separate ones of the separate tap boxes and each have a limited length corresponding to a size of the particular region of the aisle space through which the power busway extends independently of at least one other of the plurality of power busways, such that the electrical loads located in the particular region are restricted from electrically coupling with at least the other power busway.
