Built-in converter transformer core pulling plate column ring-current bypass structure

Abstract

The invention relates to a built-in converter transformer core pulling plate column ring-current bypass structure, in particular to a large-capacity converter transformer core pulling plate column ring-current bypass structure, and belongs to the technical field of transformer manufacturing. According to the technical scheme, the structure comprises a clamping piece (1), a pull plate (2), a copper compensation ring (3) and a core-lamination stack (4), the copper compensation ring (3) is arranged on the surface of the core-lamination stack (4), a short circuit loop is formed along an iron core window, and the copper compensation ring (3) is clamped and fixed to the pull plate (2) through the clamping piece (1). The built-in converter transformer core pulling plate column ring-current bypass structure has the advantages that the energy consumption of the pull plate is reduced on the premise that the structure and strength of the pull plate are not changed, eddy-current loss on iron core last-stage iron is greatly reduced, the space is saved, the structure is simple, and overall arrangement is reasonable.

Description

technical field [0001] The invention relates to a built-in converter transformer iron core tie-plate column circulation bypass structure, in particular to a large-capacity converter transformer iron core tie-plate column circulation bypass structure, which belongs to the technical field of transformer manufacturing. Background technique [0002] For high-end large-capacity converter transformers, there is inevitably the same problem, that is, the magnetic flux leakage of the tapped lead wires of the voltage regulating winding will generate an induced current in the core frame, and the strong induced current will cause a sharp loss of the pull plate resistance. Increased, so that the local overheating. Contents of the invention [0003] The object of the present invention is to provide a built-in converter transformer core pull plate inter-column circulation bypass structure, add copper compensation ring on the surface of the iron core, make the copper compensation ring for...
