Abstract

The invention relates to a winding arrangement having a high electric strength. The winding arrangement has at least two juxtaposed windings (34, 37) arranged in a row, said windings being surrounded by a barrier arrangement (38, 40) configured with insulating material. A
tubular electric shield (62, 63; 64, 65) is provided in the area of both front faces of the winding (5, 6; 7, 8; 58, 59; 60, 61) of at least one of said windings (1, 3, 4), said shield coaxially surrounding the corresponding winding (1, 2; 3, 4; 37) while leaving an intermediate gap (23A, 63A) and extending axially outward over the corresponding front face of the winding (5, 6; 7, 8;
58, 59; 60, 61) in such a way that its axial height (B) relative to the corresponding front face of the winding (58, 59) is the same or greater than half of the radial width (A) of the intermediate gap (23A, 63A).

Claims (9)

1. A winding arrangement having at least two windings (34, 37), which are arranged next to one another in a row and each of which is surrounded by a barrier arrangement (38, 40) formed with insulating material, and each having a tubular electric shield (62, 63) in the region of each of the two winding end sides (58, 59) of at least one of the windings (34), each shield (62, 63) coaxially surrounding the at least one winding (34) leaving an intermediate gap (23A) and extending axially outwards beyond the respective winding end side (58, 59) such that its axial height (B), in relation to the respective winding end side (58, 59), is equal to or greater than half the radial width (A) of the intermediate gap (23A).
2. The winding arrangement as claimed in claim 1, characterized in that the two electric shields are formed jointly with a continuous, tubular, joint shield (23, 24) which extends axially over the entire winding (1, 2).
3. The winding arrangement as claimed in claim 1 or 2, which forms an inductor for high-voltage DC
transmission systems.
4. The winding arrangement as claimed in claim 1 or 2, characterized in that each of the two windings (34;
37) forms a respective external transformer winding (34; 37) of a respective transformer winding combination (32; 33), each transformer winding combination (32; 33) having the external transformer winding (34; 37) which coaxially surrounds an internal transformer winding (35; 36).
5. The winding arrangement as claimed in claim 4, which is part of a transformer for high-voltage DC
transmission systems.
6. The winding arrangement as claimed in one of the preceding claims, characterized in that, in the region of the respective winding end side (5, 6;
7, 8; 58, 59; 60, 61), the barrier arrangement (3, 4;
38, 40) has in each case at least one outer flange ring (9-12; 42, 43, 46, 47) which engages around the radially outer winding edge (19-21).

7. The winding arrangement as claimed in one of the preceding claims, characterized in that the shields (62-64; 23, 24) each have a screen (83, 91) for field guidance purposes in the region of their ends.
8. The winding arrangement as claimed in one of the preceding claims, which is arranged in a conductive tank (26, 66) .
9. The winding arrangement as claimed in one of the preceding claims, characterized in that the windings (1, 2; 34, 37, 35, 36) each surround a core limb (67;
68) of a transformer core (25, 69).
