The mounting structure for press blocks on a wound core of a stereoscopic dry transformer open baurt

摘要

Disclosed is a mounting structure for press blocks on a wound core of a stereoscopic dry-type transformer an open construction, having three coils (1), the vertically and are arranged in a triangle, wherein an insulating ring (2) at the upper end of each of the coils (1) is arranged, a compression block (3) for pressing the corresponding coil (1) on the upper side of each insulating ring (2) is arranged, an upper clip (4) above the billets (3) is arranged, and presser rods (40) on the underside of the upper clamp (4) are arranged, in order to the press blocks (3) to press. The upper clamp presses on the press blocks and the press blocks (3) pressing on the coils, so that a loosening of the coils is prevented and impact strength of the coils is ensured. In addition, the press blocks, which does not press on the coils with a clip to be clamped by the use of a screw. For this reason, the distance between the three coils are not increased, and there, it is ensured that the insulation distance between the coils is not increased. In addition, four press blocks are uniformly distributed on each of the coils, so that the loading of the coils is uniform and the coils are pressed together to form a better.
