continuously variable induktionsstyrd voltage regulator, reglerlindning for such a procedure, as well as for governance

摘要

A step-free induction controlled voltage regulator, primarily for high-voltage regulation, includes a magnetic circuit based upon a magnetizable core (1) having one or more flux paths or legs (2) with at least one winding (3) supplying the output voltage (U). The output winding leg (2) includes a regulation arrangement (4-8) comprising a rotatable rotor means (4) carrying a regulator winding (6) electrically connected in series with the output winding (3). A compensator winding (7) can be arranged around the leg (2) and electrically connected in series with a capacitor means (8). At least one of the regulator winding (6) and the supply winding (3), or a part thereof, is wound by a high-voltage cable comprising at least one conductor surrounded by a first layer having semiconducting properties, a solid insulating layer, and a second layer having semiconducting properties.
