REDUNDANT SECONDARY POWER SUPPORT SYSTEM

摘要

A concurrently maintainable secondary power distribution system enables redundant secondary power support to electrical loads, which receive independent primary power support from separate primary power systems, via a secondary power busway. Separate bus ducts, each carrying power from a secondary power system, are coupled to opposite ends of the busway. Each bus duct can carry power from a separate secondary power system, and switching devices bridging the connections between the bus ducts and the power busway can selectively switch the power busway from one of the bus ducts to the other bus duct, thereby switching between one of the secondary power systems. The separate secondary power systems can be coupled together at various points in the respective power systems, so that one or more portions of one of the secondary power systems can distribute power received from an upstream portion of another one of the secondary power systems.

主权项

1. A data center, comprising:
an aisle space configured to provide computing capacity, wherein the aisle space comprises:
at least one row of rack computer systems extending along a length of the aisle space;at least two primary power busways extending through the aisle space in parallel with the at least one row of rack computer systems and configured to distribute primary power, received at each primary power busway of the at least two primary power busways from separate primary power systems, to the at least one row of rack computer systems to provide primary power support to the at least one row of rack computer systems; andat least one secondary power busway extending through the aisle space in parallel with the at least one row of rack computer systems, wherein the at least one secondary power busway comprises separate feed boxes at opposite ends and is configured to distribute secondary power, received in at least one of the separate feed boxes, to the at least one row of rack computer systems; and at least two bus ducts, wherein each bus duct extends along opposite ends of the length of the aisle space and is configured to distribute secondary power from at least one secondary power system to a separate one of the separate feed boxes of the at least one secondary power busway to provide redundant secondary power support to the at least one row of rack computer systems via the at least one secondary power busway.
