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. One part of the insulating tube presents a hollow cylinder with projections while its other part presents a truncated hollow cone. Each insulating tube (8) for the supply of cooling agent is separated from a subsequent tube by several insulation layers (12) serving a continuation of the corresponding layers (6) of turn-to-turn insulation, with a screen layer (13) presenting an uninterrupted continuation of the screen layer (7) of the turn-to-turn insulation layers (6).
