  • Publication number: 20150001983
    Abstract: The invention relates to a corona shield for an electrical conductor in a rotating electric machine, comprising an outer corona shield and a terminal corona shield which is mounted adjacent to the outer corona shield, on a high-voltage insulation of the electrical conductor, and also comprising a strip that has a limited electrical conductivity, is arranged around the high-voltage insulation of the electrical conductor, and is impregnated with a resin. The invention is characterized in that a paint having a limited electrical conductivity is arranged at least between the high-voltage insulation and the strip, in the transition zone between the outer corona shield and the strip of the terminal corona shield.

  • Patent number: 8922088
    Abstract: Provided is a rotor for a dynamoelectric machine. The rotor includes winding elements arranged in axially extending grooves of a rotor body, a winding head arranged axially adjacent to the rotor body, and a winding head carrier, connected to the winding head by means of tension bolts, all arranged in such a way that reliable securing of the winding head against radial expansion due to centrifugal forces is ensured, while resulting in a compact and cost-effective configuration as well as sufficient cooling.

  • Publication number: 20140175953
    Abstract: The invention concerns a monitoring device for a double-fed electrodynamic asynchronous machine, having a stator and a rotor body held rotatably therein, whose shaft is mounted on at least one bearing, and at least one insulation layer for electrical insulation of the rotor body with respect to a zero potential. The invention is characterised by at least one contact element for tapping an electric voltage, which is applied with respect to the zero potential by means of said at last one insulation layer, and a measuring and signalling unit, which is connected to the contact elements for measuring the applied voltage and is designed for emitting a warning signal depending on the height of said voltage.

  • Publication number: 20140159537
    Abstract: The invention concerns an asynchronous machine having a slip-ring rotor for use with a variable rotational speed, with a rotor, a rotor body, having grooves mounted radially into the rotor body, winding elements of the rotor, from which respectively at least one element runs axially through each of the grooves, locking elements, which co-operate in a form fit manner with the rotor body and close the grooves radially and outwardly, a high voltage insulation with outer corona protection around each of the winding elements. The invention is characterised in that between the outer corona protection of the winding element and at least one neighbouring wall of the groove in peripheral direction electrically conducting connecting means are arranged for releasable connection of the winding element with the rotor body.

  • Publication number: 20140083592
    Abstract: A method for producing an electrical insulation system of a conductor of a winding head of an electric machine is provided. The method includes applying a porous main insulation paper to the conductor of the electrical machine; applying a porous overhang corona shielding paper to the main insulation paper, as a result of which an insulation blank of the insulation system is formed; impregnating the insulation blank with a base resin, wherein the overhang corona shielding paper and the main insulation paper have a porosity such that the insulation blank is impregnated by the base resin to form a homogeneous base resin matrix; and completing the insulation system by curing the base resin.

  • Publication number: 20130187493
    Abstract: The invention relates to a rotor for a dynamoelectric machine, having the following features: winding elements which are arranged in axially extending grooves of a rotor body; a winding head which is arranged axially adjacent to the rotor body, wherein in the region of the winding head the winding elements exit the grooves in the axial direction, then extend at an angle to the axial direction, and then extend in the axial direction again in the vicinity of the axial ends of said winding elements, and are connected with further winding elements; a winding head carrier which is radially arranged within the winding head; the winding head is connected with the winding head carrier by means of tension bolts which engage at the radially outer ends thereof on support bodies, which in turn lie on the winding elements in the region of the winding head; the tension bolts penetrate the winding head in the radial direction in the axially extending areas or the areas of the bending of the winding elements from the axia
