Abstract

An elevated automatic transfer switch (ATS) cabinet provides power support redundancy to a set of electrical loads in one or more rack computer systems. The cabinet includes multiple-phase power feed input receptacles which each receive a multiple-phase power feed and distribute the separate phases of the power feed to separate ATS modules installed in the cabinet. Outputs from separate ATS modules can be distributed, via separate cabinet output receptacles, to electrical loads in one or more rack computer systems. Backup ATS modules can be installed in parallel with ATS modules, so that ATS modules can be replaced while maintaining power support. Particular bypass circuits in the cabinet can be selectively closed to bypass selected ATS modules with selected power feeds, based on manual interaction with one or more elements of the bypass circuit, including manual insertion of a conductive element into a slot element of the bypass circuit.

Dependent claims

A data center, comprising:

at least two power distribution systems configured to supply multiple-phase power;
at least one set of computer systems mounted in a rack and one or more power distribution units configured to distribute received power to the computer systems mounted in the rack;
and
at least one elevated automatic transfer switch (ATS) cabinet mounted in an elevated position above the rack, wherein automatic transfer switches of ATS modules mounted in the elevated ATS cabinet are each configured to selectively supply power, to computer systems included in the rack, from a selected one of the at least two power distribution systems,
wherein each elevated ATS cabinet of the at least one elevated ATS cabinet comprises:
at least two multiple-phase input receptacles configured to couple to at least two multiple-phase power feeds from the at least two power distribution systems, wherein each of the at least two multi-phase input receptacles are configured to distribute separate respective single-phases of a coupled multiple phase power feed to respective internal power feeds of the elevated ATS cabinet;
the respective internal power feeds, wherein the respective internal power feeds are configured to carry separate respective single-phase power feeds distributed from the at least two multi-phase input receptacles;
and
at least two ATS modules mounted in separate ATS module slots of a set of at least two ATS module slots of the elevated ATS cabinet, wherein each ATS module slot is configured to electrically couple a respective ATS module installed in the respective ATS module slot with a separate internal power feed of the respective internal power feeds of the elevated ATS cabinet, wherein the respective ATS module is coupled to the respective internal power feed of the elevated ATS cabinet based on respective blind-mate connections between a set of blind-mate slot power feed connectors of the respective ATS module slot and a set of blind-mate ATS inlet connectors of the respective ATS module.

6 more elements

An apparatus, comprising:

an elevated automatic transfer switch (ATS) cabinet configured to provide power support to a set of electrical loads via a set of ATS modules which are each configured to selectively distribute power to the electrical loads from a selected power feed, wherein the elevated ATS cabinet comprises:
a multiple-phase cabinet input receptacle configured to:
couple to a multiple-phase power transmission line;
and
distribute separate respective single-phases of a multi-phase power feed to respective separate internal power feeds of the elevated ATS cabinet;
the respective separate internal power feeds, each configured to carry a separate single-phase of the multi-phase power feed distributed from the multi-phase cabinet input receptacle;
and
a set of two or more ATS module slots, wherein each ATS module slot comprises a set of blind-mate slot power feed connectors electrically coupled to separate ones of the respective separate internal power feeds of the elevated ATS cabinet, wherein each ATS module slot is configured to electrically couple a separate ATS module installed in the respective ATS module slot with the separate ones of the internal power feeds carrying a separate single-phase of the multiple phase power feed, wherein the separate ATS module couples with the separate ones of the internal power feeds based on blind-mate connections between the set of blind-mate slot power feed connectors of the respective ATS module slot and blind-mate ATS inlet connectors of the ATS module.

5 more elements

A method, comprising:

configuring an elevated automatic transfer switch (ATS) cabinet to provide power support to a set of electrical loads via a set of ATS modules which are each configured to selectively distribute power to electrical loads from a selected power feed, wherein the configuring comprises:
coupling a multiple-phase cabinet input receptacle of the elevated ATS cabinet to a multiple-phase power transmission line carrying an individual multiple phase power feed, wherein the multiple-phase cabinet input receptacle is configured to distribute separate single phases of the individual multiple phase power feed to separate internal power feeds of the elevated ATS cabinet, wherein the separate internal power feeds are each configured to carry a separate single-phase of the multi-phase power feed distributed from the multi-phase cabinet input receptacle;
and
installing a set of two or more ATS modules in a set of two or more ATS module slots of the elevated ATS cabinet, wherein each ATS module slot comprises a set of blind-mate slot power feed connectors that are electrically coupled to a separate one of the separate internal power feeds of the elevated ATS cabinet, wherein installing a given ATS module in a given ATS module slot comprises establishing blind-mate connections between the set of blind-mate slot connectors in the given ATS module slot and blind-mate ATS inlet connectors of the given ATS module, wherein established blind-mate connections electrically couple the given ATS module with one of the separate internal power feeds configured to carry a separate single-phase of the individual multiple phase power feed.
