Abstract

The invention discloses a compacting device and method for a transformer body. The device part includes a web arranged on a transformer iron core, and also includes a plurality of compacting mechanisms arranged at intervals along the length direction of the web. Each compacting mechanism includes: The connecting piece is arranged in parallel above the pressure plate on the top of the body, and one end is fixed on the web, and the connecting piece has a threaded hole; the two ends of the laminated block are respectively against the connecting piece and the pressure plate, and the layer The top of the pressure block has a positioning hole corresponding to the threaded hole; the bolt is matched with the threaded hole, and the end extends into the positioning hole. The pressing mechanism of the present invention only includes three parts, compared with the five parts of the traditional nail sleeve structure, the structure is simpler, the production efficiency is greatly improved, and the cost is saved; the laminated block is an insulating material, which can reduce the main insulation distance , reducing the discharge probability of windings and leads.

Description

technical field [0001] The invention relates to the field of transformer manufacturing, and relates to a transformer body pressing device and method. Background technique [0002] With the expansion of power grid capacity, people have higher and higher requirements for the reliability of transformer operation in the process of power transmission. Therefore, improving the short-circuit resistance of transformer is undoubtedly the most favorable measure to improve the reliability of transformer operation. In the production of transformers, under the condition that other factors remain unchanged, to improve the short-circuit resistance of transformers, it is necessary to improve the reliability of the compact structure of the transformer body. [0003] Such as figure 1 As shown, it is a schematic diagram of an existing nail-type pressing device, which includes a web 1 and a connecting piece 2 whose end is fixed on the web 1. Press the nail set on the top to compress the body,...
