The invention belongs to the technical field of dry-type transformers and further discloses a dry-type transformer winding structure. The structure comprises an iron core, wherein an inner winding iswound on a circumferential surface of the iron core, an outer wall, close to the inner winding, of the circumferential surface of the iron core is sleeved with an outer winding insulating layer, an outer winding is wound on an outer wall, close to the outer winding insulating layer, of the circumferential surface of the iron core, an adjusting hole is formed in the iron core, two adjusting rods are symmetrically mounted in the adjusting hole, and supporting plates are mounted at opposite ends of the two adjusting rods. The structure is advantaged in that the two adjusting rods are pulled, theadjusting rods are moved to the position, needed by a user, in the adjusting hole, the adjusting rods and a supporting plate are fixed by screwing down an adjusting bolt, the supporting plate abuts against a transformer outer frame, the device can be adjusted according to the transformer outer frame, the structure can be suitable for transformer outer frames of different specifications, and a application range of the structure is widened.
Description
technical field [0001] The invention belongs to the technical field of dry-type transformers, and in particular relates to a winding structure of a dry-type transformer. Background technique [0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. The cooling method is divided into natural air cooling ( AN) and forced air cooling (AF), when natural air cooling, the transformer can run continuously at the rated capacity for a long time, when forced air cooling, the output capacity of the transformer can be increased by 50%, suitable for intermittent overload operation, or emergency accident overload Operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operating state, so it should not be placed in continuous ov...
