Abstract
Terminal boxes for large dynamoelectric machines provide a housing for high voltage terminal bushings which connect the dynamoelectric machine with a power grid. The stray flux from the terminal bushings induces eddy and circulating currents in the terminal box walls and consequent heating of the walls. To limit wall temperatures water is circulated through sealed flow channels fabricated to the terminal box walls and in series with the terminal bushings flow circuit. A preferred wall construction comprises an outer wall of stainless steel clad carbon steel and an inner wall of stainless steel.
