Description

Technical Field

[0001] The present invention relates to the technical field of dry-type transformers, and particularly to an adjustable dry-type transformer. Background Art

[0002] As one of many types of transformers, the installation process of dry-type transformers in the prior art is complex and not easy to disassemble, and it is also not easy to adjust them during hoisting.

[0003] Among them, the patent with publication number CN214848037U discloses an adjustable installation structure for a dry-type transformer, including a dry-type transformer, columns and an installation platform. Both ends of the installation platform are fixedly connected to the columns. A rotating platform is arranged above the installation platform. The bottom of the rotating platform is connected with a rotating shaft, and the rotating shaft is connected to the surface of the installation platform. The dry-type transformer is arranged on the surface of the rotating platform. A chute is opened on the surface of the rotating platform, and a clamping plate is installed in the chute. The clamping plate is threadedly connected with an adjusting screw rod. The adjusting screw rod is arranged in a rotating groove. The rotating groove is opened on the side walls of both sides of the rotating platform. The adjusting screw rod is connected to the inner wall of the rotating groove. One end of the adjusting screw rod is fixedly connected with a rotating handwheel. There are still defects in this technical solution:

[0004] In this technical solution, only the screw rod is used to drive the clamping plate to move to clamp and limit the transformer. However, the transformer will generate vibration during operation. Therefore, during long-term use, it is easy to cause the screw rod to rotate, which in turn causes the clamping plate to loosen, resulting in the transformer losing the only limit, and further leading to the risk of the transformer falling. Summary of the Invention

It solves the problem that in the adjustable installation structure of the dry-type transformer in the prior art, only the screw rod is used to drive the clamping plate to move to clamp and limit the transformer. However, the transformer will generate vibration during operation. Therefore, during long-term use, it is easy to cause the screw rod to rotate, which in turn causes the clamping plate to loosen, resulting in the transformer losing the only limit, and further leading to the risk of the transformer falling.
