摘要: The invention relates to a rotating electric machine having a stator (1) with windings drawn through slots (5) in the stator. According to the invention the windings consist of high-voltage cable (6), the cable lead-throughs being surrounded by a casting compound in each slot (5). The invention also relates to a method in the manufacture of such a machine in which the stator is first wound with high-voltage cable, after which a casting compound in fluid or semi-fluid state is introduced into the slot.

摘要: The magnetic circuit of a generator in a hydro-generator plant is arranged to directly supply a high supply voltage of 20-800 kV, preferably higher than 36 kV. The generator is provided with solid insulation and its winding includes a cable (6) comprising one or more current-carrying conductors (31) with a number of strands (36) surrounded by at least one outer and one inner semiconducting layer (34, 32) and intermediate insulating layers (33). The outer semiconducting layer (34) is at earth potential. The stator winding may be produced with full or fractional slot winding, the phases of the winding being Y-connected. The Y-point may be insulated and protected from over-voltage by means of surge arresters, or else the Y-point may be earthed via a suppression filter. The invention also relates to a hydro-generator plant, a generator included in the plant and a procedure for building such a plant.

摘要: An insulated DC-cable and method for production of an insulated DC-cable with an insulating system comprising an extruded cross-linked polyethylene based insulation disposed around the conductor. The extruded polyethylene based compound comprises additives such as cross-linking agent, scorch retarding agent and antioxidant. The scorch retarding agent comprises a compound (D), 2,4-diphenyl-4-methyl-pentene-1 and the antioxidant comprises a compound (C), a diester of 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionicacid and thiodiglycol. The compounded polyethylene based resin composition is extruded and cross-linked at a temperature and for a period of time sufficient enough to cross link the insulation. The temperature and the period of time upon extrusion and cross-linking are limited so as to substantially suppresss or essentially avoid undesired polar by-products being formed in the cross-linked composition.

摘要: A device for mechanically securing and controlling the potential of winding cables (10) outer semiconducting layers (14) in the end windings region of the stator (2) of a rotating high-voltage electric machine comprises spacers (12) of resilient, electrically conducting material arranged between the semi-conducting outer layers (14) of adjacent winding cables (10, 10', 10''). Positioning devices (16, 18) are arranged to secure the cables in relation to each other with the outer layers in contact with the spacers. Means are also provided to connect the cables outer semiconducting layers and spacers with a reference potential (28).

摘要: In a plant containing a turbo-generator the magnetic circuit of the turbo-generator is included in an electric generator which directly supplies a high supply voltage of 20-800 kV, preferably higher than 36 kV. The insulation of the generator is built up of a cable (6) comprising one or more current-carrying conductors (31) with a number of strands (36) surrounded by outer and inner semiconducting layers (34, 32) and intermediate insulating layers (33). The outer semiconducting layer (34) is at earth potential. The phases of the winding are Y-connected. The Y-point may be insulated and protected from over-voltage by means of surge arresters, or else the Y-point may be earthed via a suppression filter.
