Abstract:
An enclosure for a collector set on a turbine generator includes a non-conducting transverse baffle which divides the enclosure into a separate compartment for each polarity. An aperture in the baffle forms with the generator shaft an annular passage through which cooling air passes from one compartment to the other and in so doing flows directly over the collector ring and brush sets in each compartment to provide more efficient cooling. A removable housing is guided into place over the collector set by a grooved guide which engages the top edge of the baffle and forms a seal between compartments. Single doors on each side of the housing provide access to both polarities and carry a seal, which mates with the baffle with the doors closed, to force the air to pass through the annular passage. An insulated safety handle above each door provides support when leaning inward to change brushes with the generator at full load, and discourages inserting both hands into the enclosure at once.
