Abstract

A transformer having a transformer core that forms a magnetic flux path between and through a top yoke, leg, and bottom yoke of the transformer core. A winding can be disposed about the leg. Further, a flitch plate, which can have at least one slot that is configured to reduce eddy losses generated by the winding, can be disposed adjacent to the leg and extend between the top yoke and the bottom yoke. The flitch plate can be clamped to the top and bottom yokes by top and bottom clamps, respectively. The top and bottom clamps can each include at least one cutout that reduces an attraction of stray flux from the winding and into the corresponding top and bottom clamps. Additionally, at least one of the top clamp and the bottom clamp can include an internal lattice structure.

Description

technical field [0001] The present application relates generally to transformers and, more particularly, to core clamping structures for transformers. Background technique [0002] Electrical systems and equipment, such as transformers, remain an area of ​​concern. Some existing systems have various weaknesses, disadvantages and deficiencies with respect to certain applications. For example, transformers include clamping systems that may experience relatively high temperatures during operation, which may damage the transformer and / or shorten the life of the transformer. In addition, at least some types of transformers attempt to prevent at least some operating temperatures from exceeding temperature limits by increasing the size of at least some transformer components, the size of the transformer tank, and the amount of cooling medium (such as oil) in the transformer tank . However, such an effort may increase the size and weight of the transformer and associated system, ...
