External circulation bypass structure between converter transformer core pulling plate columns

Abstract

The invention relates to an external circulation bypass structure between converter transformer core pulling plate columns, in particular to a circulation bypass structure between large-capacity converter transformer core pulling plate columns, and belongs to the technical field of transformer manufacturing. According to the technical scheme, a plurality of copper cables (4) are arranged in a conductor grip frame (3), the copper cables are connected with coil outgoing wires and then connected with an upper clamp and a lower clamp, and the copper cables, the upper clamp, the lower clamp and core main column pulling plates form short circuit rings (2) along core windows. The external circulation bypass structure has the advantages that on the premise that the structure and the strength of the pulling plates are not changed, losses of the pulling plates are reduced, eddy current losses of cores are greatly reduced, leakage flux is restrained, the structure is simple, and layout is reasonable.

Description

technical field [0001] The invention relates to an external 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 an external converter transformer core tie plate circulation bypass structure, the copper cable, the upper and lower clamps and the iron core main column tie plate form a short-circuit ring ...
