Multi-path cooling of a turbo-generator rotor winding

A turbo-generator has a rotor 1 with direct fluid cooling, the rotor 1 comprising a rotor winding 2 arranged around a central rotor body. Each rotor conductor has axial cooling ducts A, B and a sub slot 3 below the main winding slot. The rotor is characterized in that the axial cooling ducts A, B ar...

Zusammenfassung:A turbo-generator has a rotor 1 with direct fluid cooling, the rotor 1 comprising a rotor winding 2 arranged around a central rotor body. Each rotor conductor has axial cooling ducts A, B and a sub slot 3 below the main winding slot. The rotor is characterized in that the axial cooling ducts A, B are provided as parallel twin ducts for multi-path cooling, and that the inlets 4 and outlets 5 of the flow paths in adjacent axial ducts A, B within one conductor are offset from each other. A turbo-generator having improved cooling of the rotor windings, minimizing hotspot temperatures within the rotor winding conductors, is thus provided.
