Description

Technical Field

[0001] The utility model relates to a transformer switch gear position switching tooling, belonging to the technical field of transformer wire welding test. Background Art

[0002] During the production process of a transformer, wire welding test must be passed before subsequent furnace drying. In the past, when a transformer was doing wire welding test, if an electric drive mechanism was used to switch the switch gear position through a switch gear box and a switch shaft, the operation must be carried out when the transformer body was installed inside the oil tank and the cover was buckled. This was because the connecting bracket for installing the switch gear box needed to be installed on the body cover before it could be used. Due to factors such as the arrival cycle of materials and the arrangement of personnel and sites, other components inside the transformer box may not be assembled completely during the test. At this time, it was necessary to open the body cover again, which not only required a large amount of manpower and material resources, but also had a greater impact. Content of the Utility Model

[0003] The purpose of the utility model is to provide a transformer switch gear position switching tooling. When in use, one end of the tooling body is fixed on the flange of the switch, and the other end is installed with a gear box, which can realize switching the switch gear position by using an electric drive mechanism without buckling the cover, and solve the above problems existing in the background art.

[0004] The technical solution of the utility model is as follows:

[0005] A transformer switch gear position switching tooling includes a tooling body, which is composed of an integrally formed left arc plate and a right connecting plate. The left arc plate is provided with a plurality of bolt holes I along the circumferential direction. The left arc plate and the flange of the switch are arranged up and down and are connected by bolts. The right connecting plate extends outwards from the transformer. The right connecting plate is provided with a through hole and bolt holes II distributed around the through hole. The gear box is connected to the right connecting plate through bolts and bolt holes II. The gear box is flush with the switch head cover. One end of the switch shaft A is connected to the switch driving device, and the other end of the switch shaft A passes through the through hole on the right connecting plate and is connected to the gear in the gear box. The transmission shaft of the gear box is connected to the switch head cover through the switch shaft B.

[0006] Further, the left arc plate is a strip-shaped arc plate, the middle position of which is integrally connected to one end of the right connecting plate. The other end of the right connecting plate far from the left arc plate is provided with a through hole, and four bolt holes II are distributed around the through hole.

[0007] Further, the right connecting plate is of a trapezoidal structure. One side of the left arc plate is integrally connected to the bottom edge of the right connecting plate. The other end of the right connecting plate far from the left arc plate is provided with a through hole, and two bolt holes II are distributed before and after on both sides of the through hole.

[0008] Positive effects of the utility model: It can realize the switching of the switch gear position by using an electric drive mechanism in the state where the transformer box body is not covered, optimizing the process flow and improving the work efficiency. Description of the Drawings
