Abstract

771,770. Cooling dynamo-electric machines. ALLIS - CHALMERS MANUFACTURING CO. April 13, 1955 [May 20, 1954], No. 10699/55. Class 35. In a gas-cooled machine, gas is applied to the interconnecting leads and terminals in the form of jets from suitably located nozzles. As shown, hydrogen or other gas passes from the fan 16 over the cooler 43 to the high pressure end 41 of the machine whence it returns through the air gap and ducts in the stator and rotor slots, in contact with the conductors, to the fan. Some of the gas from the high pressure end passes through openings 46 into and traverses spaced axial channels 45 near the ends of which are pipes 47 terminating in nozzles 49 so located as to blow jets of gas into apertures 30 in the terminal bushings and other apertures in hollow leads 22 serving as inter-phase conductors. T-terminal studs 26 terminate in bushings 29 (Fig. 6), fitted with radiating fins 28, also tubular conductors 23 through which the gas travels circumferentially until it reaches an outlet in the low-pressure chamber 40, connections being made to the end winding at appropriate points. Similar gas exits are provided in the leads 22.
