Embodiment Construction

[0016] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0017] A transformer lung lobe shielding stacking process, which is stacked from the inside of the insulating part, including the following steps:

[0018] 1) Fix the insulating part on the stacking platform, and use a metal baffle to block the opening end of the insulating part, so that the inner cavity of the insulating part forms a closed structure;

[0019] 2) When stacking, the silicon steel sheets are stacked from the non-center side to the center side, so that the two ends of the silicon steel sheet and the insulating part form a self-locking structure; the straight section of the inner cavity of the insulating part and the end of the metal baffle are one end of the silicon steel sheet Positioning, the other end of the silicon steel sheet forms the shape of the lung lobe according to the length of the silicon steel sheet;

[0020] 3) Bru...

Abstract

The invention relates to a lung-shaped shield stacking technology for a transformer, and belongs to the technical field of transformers. The technical scheme is that the shield structure at the end part of the high-capacity transformer body is lung-shaped, namely, silicon steel plates are inserted into an insulating body support plate and an insulating press plate; a lung-shaped inner cavity is formed through processing, the silicon steel plates are stacked one by one in the insulating part, and the silicon steel plates with different lengths are utilized to form the outline and round corners of the lung shape and fill the whole inner cavity of the insulating part. The lung-shaped shield stacking technology for the transformer has the advantages that, the lung-shaped shielding silicon steel plate adopted by the end part of the transformer body are arranged in the insulating press plate and the support plate, so that the leakage flux problem of the end part of the coil is effectively solved, the whole shielding structure of the transformer is simplified, and the shielding effect is improved.

Description

technical field [0001] The invention relates to a shielding stacking process of transformer lung lobes, which belongs to the technical field of transformers. Background technique [0002] The role of transformer magnetic shielding is to prevent the coil winding and magnetic core (iron core) of the transformer from radiating electromagnetic interference and affecting the normal operation of surrounding electronic circuits. The existing problems in the background technology are: the magnetic shielding process used for the end of the transformer body is unreasonable, and the magnetic flux leakage at the end of the coil is likely to occur, the overall shielding structure of the transformer is complicated, and the shielding effect is not ideal. Contents of the invention [0003] The purpose of the present invention is to provide a transformer lung lobe shielding stacking process. The end of the transformer body adopts the lung leaf-shaped shielding silicon steel sheet and arran...
