Abstract: A coupling unit for two multilayer cables of a stator winding of a high-voltage generator, located in the end-face portion thereof, comprises terminations (1) of interconnected multilayer cables, wherein conducting layers (2,10) and conducting layer tubes (6,8) are concentrically arranged and separated from one another by insulating layers (7, 9, 14, 15), jumpers (18, 20, 22, 24) electrically coupling said conducting layers (2, 10) and conducting layer tubes (6, 8). A portion of each insulating layer (7, 9, 14, 15), facing the jumpers (18, 20, 22, 24) has a shape of an end insulation frustum (16). Each jumper (18, 20, 22, 24) is a totality of components made as a portion of a hollow cylinder limited by two planes. Each jumper (18, 20, 22, 24) carries an insulating bushing (12, 21, 23, 25). Thin-walled insulation cylinders (27, 28) are secured in each end insulation frustums (26) and in frustums (26) of the insulation bushings (19, 21, 23, 25).

Abstract: A coupling unit for connection of a generator high-voltage winding lead-out and a cable comprises a casing (1) wherein a generator high-voltage winding lead-out (5) with sheaths (6) and a cable termination (3) are arranged, their current carrying elements (8) being linked by a power jumper (9).

Abstract: The stator coil of a high-voltage generator comprises an electrical lead-in (1) of conductive material, turns (2) of conductive material coated with layers (6) of turn-to-turn insulation with a screen layer (7). The electrical lead-in (1) is fashioned as a tube. The stator coil of a high-voltage generator further comprises cooling pipes (3) adjoining the turns (2) and having side openings (4, 5), and insulating members (9). Each insulating member (8) consists of two parts (10, 11) made integral with each other. A portion of the first part (10), facing the coil turns (2), has two projections with holes communicated with the side openings (4 or 5) in the cooling pipes (3). The insulating member (9) is provided with passages communicated with spaces in the projections. The insulating members (9) are arranged concentrically with the electrical lead-in tube (1), and each pair of said insulating members forms an insulating tube (8) for the supply of cooling agent, made up of two parts.

Abstract: A stator of a generator, which stator comprises a housing accommodating a slotted magnetic core 2, a dielectric oil-separating cylinder 4 arranged next to the internal surface of the magnetic core, and a winding composed of two series-connected half-windings 7, 8, each composed, in turn, of high-voltage elements 6. The high-voltage elements 6 of one half-winding 8 in the slotted part of the stator are placed in insulation sleeves 14 which have hollow projections 15 on their internal surfaces. Placed between the hollow projections is a thermosetting compound. The part of each insulation sleeve, which extends beyond the slotted part of the stator, has a cylindrical portion integral with a cone-shaped cable-type termination reinforced with current-carrying layers.

Abstract: A coupling unit for connection of a generator high-voltage winding and an let bar comprises summary turns of the generator high-voltage winding made up of conducting layers which are insulated conductors connected in the zone of the high-voltage lead-in with the inlet bar (17) and cooling ducts. Summary turns of the generator high-voltage winding are made as concentrically arranged tubes (5,7,9,11,12) connected to one another in the zone of the high-voltage lead-in by means of template tubular elements (16) providing for gradual change over of the tube (5) of the first summary turn into a tube (7) of the second summary turn, of the tube (7) of the second summary turn into a tube (9) of the third summary turn and so on until the tube (9) of the penultimate summary turn becomes the tube (11,12) of the last summary turn of the generator high-voltage winding. Cooling ducts are divided into a central duct (6) and peripheral ducts (15) for cooling.

Abstract: A device for attachment of coil ends in a generator stator high-voltage winding includes insulation spacers (13) disposed on external surfaces of the coil end bars (16), auxiliary spacers disposed between coil end bars (16), a case (1), spring stops (15) anchored inside the case (1), and planks (14). The case (1) is made of two coaxial truncated-cone members (2 and 3) and a part of a torus member (4) made integral therewith and incorporating a joint (5) with a seal (6). Each plank (14) is arranged between two insulation spacers (13), and the insulation spacers (13) are arranged between the coil end bars (16) and the spring stops (15). The insulation spacers (13), the planks (14), the spring (15) and a side surface of the case (1) form cooling passages.
