Abstract
A fluidly cooled flat plate neutral bus for electrically connecting the neutral bushings on dynamoelectric machines. The current carrying flat plate is in heat transmissive contact with a coolant carrying conduit which transfers heat generated in the neutral bus to the coolant flowing therethrough. The fluidly cooled flat plate neutral bus provides high heat flux while occupying a small volume. PAC BACKGROUND OF THE INVENTION 1. Field of the Invention: This invention relates to the neutral bushings on dynamoelectric electric machines, and more particularly to means for electrically connecting those neutral bushings and means for cooling the electrically connecting means. 2. Description of the Prior Art: Large turbine generators often have several (three for a three-phase machine) neutral lead bushings which are electrically connected by a bus. Several schemes have been utilized in the past to remove the heat generated in the bus as a result of the current flow therethrough during generator operation. For some small generators satisfactory cooling of the bus was obtained by natural convection while larger machines required a forced convection air flow to maintain the bus at an accep…
