发明名称 Gas-cooled electrical machine
摘要 In a gas-cooled electrical machine, the conductor bars (3, 4) in the winding overhang are cooled directly by a flow element of the cooling gas flow which is passed through cooling channels (8) located within the eyes (5a, 5b) of the bar ends. To this end, the bar levels of the winding bars, which are designed as a two-level bar, are spaced apart from one another in the eye region, and thus form a radial cooling channel (8). These radial cooling channels (8) are coupled to the discharge eyes (5b) by pipe connections (10) which are connected electrically, and in terms of the flow, to round connections (20). The cooling channels (9) in the round connections (20) are connected by means of insulating tubes (31) or insulating hoses to an induction area (32) of the machine fan, which is separated from the winding overhang area (30) by a bulkhead wall (33). The invention allows the bar ends and the round connections (20) connected to them in the winding overhang to be cooled optimally, since the cooling is direct.
