摘要： A rotating electrical machine and method for making the machine, where the machine includes a high-voltage stator winding and elongated support devices for supporting the winding. The machine and method employ an arrangement of cable that is made of inner conductive strands, covered with a first semiconducting layer, which is covered with an insulating layer, which is covered with a second semiconducting layer. The cable is wound in slots in the stator such that separate cable lead-throughs are positioned in specific arrangements with respect to each other and in slots of the stator. The arrangement of the cable in the stator protects the integrity of the respective components in the cable and particularly the second semiconducting layer.

摘要： For a method of operating of a synchronous compensator including a rotating electric machine including a rotor and a stator with at least one winding with a solid insulation enclosing the electric field, relevant parameters for temperature conditions in the rotor are determined, and during over-excited operation, to temporarily enlarge the field of operation of the synchronous compensator, cooling of the rotor is forced depending on a rotor temperature value determined from the parameters. The synchronous compensator measures parameters relevant for the temperature conditions of the rotor. A mechanism is also provided to force the cooling of the rotor depending on rotor temperature values determined from the parameters during over-excited operation of the electric machine.

摘要： The present invention relates to a laminated magnetic core for rotating electric machines. The laminated magnetic core comprises a number of stack members (40), each consisting of a number of sheets of metal joined together. Each stack member (40) is provided with two identical grooves (42) arranged to cooperate with wedge members (46) designed to join the stack members (40). The cross-sectional area of the groove (42) is larger than the cross-sectional area of the wedge member (46) and the wedge member (46) has two protrusions arranged symmetrically in relation to the longitudinal axis of the wedge member. The groove (42) has at least one part shaped to fit said protrusion. The stack members (40) in the laminated magnetic core are stacked on and partially overlapping each other to form different layers of stack members (40). The grooves (42) in the stack members (40) in the various layers are arranged substantially opposite each other with the wedge members (46) arranged in the grooves (42) and a protrusion abutting the complementary shape of the groove (42) in such a manner that the stack members (40) in one layer are secured counter-clockwise in tangential direction and that the stack members in at least one of the adjacent layers are secured clockwise in tangential direction. The laminated magnetic core also includes locking members arranged at least at the transition between layers secured clockwise and layers secured counter-clockwise in order to prevent tangential movement between the different layers.
