ABSTRACT:
Device for electrically connecting a three-phase current exciter to rotating rectifiers includes support wheels fixed to the shaft of the exciter and insulatedly carrying the rotating rectifiers, the support wheels comprising intermediate rings formed of non-magnetic material mounted on the shaft, three-phase current connecting conductors distributed uniformly around the peripheral surface of the shaft and secured thereon against centrifugal force effects, the three-phase connecting conductors being formed of open-ended tubes, connecting conductor lengths extending through respective passageways formed in the intermediate rings in insulated relationship to the intermediate rings, the connecting conductor lengths being disposed at a greater distance diametrically from the shaft than the open-ended tubes and being of solid construction, and radial connecting members connecting the open-ended tubes to the respective connecting conductor lengths in vicinity of the support wheels, the connecting conductor lengths having portions thereof projecting laterally out of the intermediate ring passageways forward of the connection thereof to the radial connecting members whereby the projecting portions of the connecting conductor lengths act as fan blades during rotation of the exciter shaft.
