ROTATING ELECTRICAL MACHINE, NAMELY ASYNCHRONOUS ELECTRICAL MACHINE OF DOUBLE-WAY FEED IN POWER RANGE OF 20 MV A TO 500 MV A AND HIGHER |
摘要 |
FIELD: electricity.SUBSTANCE: invention relates to electrical engineering and can be used in a rotating electrical machine, and namely an asynchronous electrical machine of double-way feed in the power range of 20 MV·A to 500 MV·A. The asynchronous electrical machine of double-way feed includes a rotor rotated about the axis and concentrically enveloped by a stator; the stator includes rotor pack (14) assembled of metal sheets divided into layers and pressed in axial direction for attachment; the above rotor pack is divided in radial direction into internal mechanical zone (14b) and external electrical zone (14a), and in which rotor winding (18) is located in electrical zone (14a). Axial clamping of the pack of rotor sheets of such a machine is optimised by the fact that rotor sheet pack (14) in mechanical zone (14b) is pressed by means of shear bolts (22) going in axial direction through rotor sheet pack (14) and in electrical zone (14a) - by means of other bolts (21).EFFECT: providing protection of insulation against damages.13 cl, 10 dwg |
