Matrix power transformer system, modular power transformer, and method of assembling same

Abstract

A unique modular power transformer system, method, technique and apparatus are disclosed. One exemplary embodiment is a matrix power transformer comprising a plurality of block assemblies, each block assembly comprising a plurality of transformer modules, each transformer module comprising a primary winding coupled to an input and a secondary winding coupled to an output, in a block assembly The inputs of each transformer block in are coupled together, and the outputs of each transformer block are coupled together. One of the secondary windings includes a plurality of taps configured to be selectively coupled to the output of the associated transformer module assembly, or selectively coupled to another secondary of the associated module assembly winding.

[0002] This application claims the benefit of priority under 35 U.S.C. 119(e) of U.S. Provisional Application Serial No. 62 / 489,197, entitled "Flexible Voltage Transformation System," filed April 24, 2017, The entire contents of this US provisional application are incorporated herein by reference. technical field

[0003] The present disclosure relates to modular power transformers, and more particularly to power transformers that include a plurality of transformer modules that are selectively interconnected. Background technique

[0004] Power transformers are used in the transmission of energy from the point of energy generation to the point of energy use. The energy generated is typically transmitted at high voltage over long distances to a substation where a transformer reduces the voltage level of the transmitted power for use by consumers.

[0005] Power transformers include primary windings that receive varying curre...
