Patent ID: 7839642

Claim:
An electrical device with a support system comprising: a pair of opposing frame members operable to supply a supporting force; three electrical bussing members disposed between the opposing frame members; three heat-sink assemblies associated with a respective electrical bussing member, each including at least one heat sink and a rectifier puck in heat-transferring relation with at least one heat sink, the heat-sink assemblies operable to transfer heat from the pucks to a fluid flowing across the heat-sink assemblies; and a plurality of insulation members separating the three heat-sink assemblies and electrically isolating the three heat-sink assemblies from one another, wherein each one of the three heat-sink assemblies and respective electrical bussing member is associated with a different phase of a three-phase electric power supply, said frame members support the three heat-sink assemblies and the insulation members, and during an electrical fault condition of the electrical device, a first one of the three heat sink assemblies electrical bussing members produces a first electromagnetic force of a first magnitude in a first direction, a second one of the electrical bussing members produces a second electromagnetic force of a second magnitude in a second direction, and a third one of the electrical bussing members produces a third electromagnetic force of a third magnitude in a third direction, and at least two of the first, second, and third forces at least partially cancel one another out thereby reducing a total force caused by the fault condition that is transferred to the frame members.
