Technical Field

[0001] The utility model relates to the technical field of transformer components, in particular to a transformer eccentric combined insulating ring body positioning structure. Background Art

[0002] The transformer body positioning is used to limit the transformer body and the oil tank to prevent relative displacement between the transformer body and the oil tank during transportation or operation, and to avoid damage to the transformer body due to impact.

[0003] The traditional transformer body positioning structure is a square positioning structure. Since the position deviation of each transformer body relative to the oil tank is uncertain, adjustment gaskets need to be placed in four directions to ensure that there is no gap between the transformer body positioning and the tank cover flange.

[0005] In view of this, we propose a transformer eccentric combined insulating ring body positioning structure. Utility Model Content

[0034] The utility model provides an eccentric concave insulating ring 201 and an eccentric convex insulating ring 202, and has the advantages of rotating the eccentric concave insulating ring 201 and the eccentric convex insulating ring 202, so as to adjust the gap between the positioning rod 5 and the positioning flange 1 at a certain distance and at any angle, thereby eliminating the influence of the cumulative tolerance of the transformer body positioning, and solving the problem that the number of adjusting gaskets used in the traditional transformer body positioning structure is uncertain and difficult to control.

[0035] Specifically, the outer ring on the bottom side of the eccentric concave insulating ring 201 contacts and cooperates with the annular protrusion on the bottom side of the inner ring wall of the positioning flange 1; after the eccentric concave insulating ring 201 is embedded in the positioning flange 1, the eccentric concave insulating ring 201 is supported by the annular protrusion on the bottom side of the inner ring wall of the positioning flange 1, and the eccentric concave insulating ring 201 is kept stable in the positioning flange 1 by the extrusion of the clamping bolt 3.

[0036] Furthermore, the cross section of the eccentric convex insulating ring 202 is T-shaped, and the eccentric convex insulating ring 202 is matched with the eccentric hole of the eccentric concave insulating ring 201 .

[0037] The utility model has the advantage that the eccentric convex insulating ring 202 with a T-shaped cross-section is provided, and the eccentric hole embedding connection between the T-shaped eccentric convex insulating ring 202 and the eccentric concave insulating ring 201 is more stable, and the eccentric convex insulating ring 202 is squeezed by the tightening bolt 3 so that the eccentric convex insulating ring 202 and the eccentric concave insulating ring 201 form a stable eccentric combined insulating ring 2.

During the installation process, according to the gap between the positioning rod 5 and the positioning flange 1, the eccentric concave insulating ring 201 and the eccentric convex insulating ring 202 are relatively rotated to adjust the gap between the positioning rod 5 and the positioning flange 1 until there is no gap between the positioning rod 5 and the positioning flange 1, thereby eliminating the influence of the cumulative tolerance of the transformer body positioning.
