1501072 Mounting rectifiers in dynamoelectric machines KRAFTWERK UNION AG 16 Feb 1976 [17 March 1975] 06039/76 Heading H2A In a rectifier assembly arranged to rotate with the shaft 1 of an electrical machine, a discshaped rectifier 8 is mounted between two clamping members 9, 10 and held in position and in contact with an electrical connector 14 by a compression spring 19. The drawing illustrates one of two rectifier carrier wheels on the shaft 1, the rectifier assembly being secured to the conventional flange 6 by bolts 11. The A.C. input lead 14 is a flexible strap whlch carries a contact 16 and a pressure member 17, the latter having a threaded extension 18 surrounded by the spring 19 which is pre-stressed by a bolt 22 engaging the extension of the pressure member. The bolt 22 is removed after assembly. The outer clamping member 9 serves as a heat sink for the rectifier. In addition, ventilation apertures 23, 24 are formed in the inner clamping member 10. |
