Clamping mechanism used for transformer core

Abstract

The invention provides a clamping mechanism used for a transformer core. The clamping mechanism comprises a bottom clamping plate, side clamping plates, and a cover clamping plate. The bottoms of the side clamping plates are fixedly connected with the left side and the right side of the bottom clamping plate. The cover clamping plate is screwed with the top of the side clamping plates. The bottom clamping plate, the side clamping plates, and the cover clamping plate form a clamping space clamping an iron core. The lower surface of the cover clamping plate is provided with a clamping groove corresponding to the top of the iron core. The upper surface of the bottom clamping plate is provided with a positioning column used to position the iron core. The front side and the rear side of the bottom clamping plate are provided with fixing portions extending outward horizontally. Through cooperation of the cover clamping plate and the bottom clamping plate, clamping and fixation of the iron core on a vertical direction are realized. Through cooperation of the side clamping plates and the front and rear clamping plates, clamping and fixation of the iron core on a horizontal direction are realized. Through the positioning column and the clamping groove, positioning of the iron core in the clamping space is realized. In a hoisting and carrying process of a transformer, the clamping device bears most external forces, and reliably prevents the iron core from being extruded and stretched and distorted.

Description

technical field [0001] The invention belongs to the field of transformers, in particular to a clamp for transformers. Background technique [0002] In the transformer, the iron core plays the role of magnetic conduction and support, and coil windings are wound on it. In order to avoid electromagnetic interference between each coil winding, a clamping device needs to be installed outside the iron core. In the prior art, multiple channel steels are mostly used. The clamping frame is surrounded by screws and bolts, but because the bottom of the clamping frame is essentially a quadrilateral structure, which is an unstable geometric shape, it is prone to deformation during the handling and hoisting of the transformer, resulting in the contact of adjacent coil windings. Extruded, the coil winding is deformed. Contents of the invention [0003] The problem to be solved by the present invention is to provide a clamping mechanism for the iron core of a transformer, which can withs...
