Abstract
722,151. Cooling dynamo electric machines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 13, 1952 [Sept. 28, 1951], No. 20359/52. Class 35. The invention relates to the cooling of high voltage stator windings by fluid under pressure passed through ducts in the conductor slots and over heat exchangers. As shown, ducts 14 of lightly insulated poor conducting metal through which gas, preferably hydrogen, is passed under pressure, are disposed between stacks of conductors, and the main conductor insulation is provided by a sheath enclosing the whole assembly as shown in Fig. 7. The ducts may be continued throughout the end windings. Axially disposed gas coolers may be disposed between the stator core and easing and the gas may traverse radial or axial ducts in the stator core. In one form gas passes axially through all the ducts 14 in parallel from one end of the machine to the other in the same direction before passing to the coolers but in another form, gas flows throughout the length of the stator but in opposite directions in adjacent slots, the blower at one end of the rotor passing gas into half of the number of conductor slots, the other slots being fed from the other end. In a third form gas enters all the conductor slots at both ends and flows towards the centre of the machine where the slots, conductors and sheaths are arranged as shown in Fig. 13 over a small part of their length to enable the gas to emerge from ducts 14 and pass into radial ducts at or near the centre of the stator core. Specification 722,152 is referred to. Reference has been directed by the Comptroller to Specification 682,340.
