Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] The invention provides a transformer group, which can solve the problem in the prior art that the three-phase axial double-split transformer used in the power conversion system is prone to failure when the load of the converter is unbalanced.

[0054] Such as figure 1 As shown, the embodiment of the present invention discloses a transformer group, including:

[0055] Three double-column single-phase transformers; wherein: the three double-column single...

Abstract

The invention discloses a transformer set. The transformer set includes three dual-column single-phase transformers, wherein the dual-column single-phase transformers respectively include a first corecolumn of a rectangular frame core, a second core column, a high voltage coil and a low voltage coil disposed on the first core column, and a high voltage coil and a low voltage coil disposed on thesecond core column. The transformer set is advantaged in that each core column includes only one low voltage coil, the magnetic coupling relationship along the low voltage coils is avoided, so leakageof a magnetic field due to unbalanced loads is avoided, eddy current loss is further avoided, and a problem of transformer fault caused by the unbalanced loads is avoided, moreover, compared with a three-phase axial dual-split transformer in the prior art, the three-phase dual-column dual-split transformer set is utilized, and the transformer set is safer and more reliable.

Description

[0001] This application claims the priority of the aforementioned invention application submitted to the China Patent Office on December 21, 2018, the application number is 201811574536.9, and the application name is "transformer group", and the aforementioned application submitted to the China Patent Office on December 21, 2018 The priority of utility model application No. 201822159503.X, application name "transformer set", the entire contents of the above two applications are incorporated in this application by reference. technical field [0002] The invention relates to the technical field of power systems, in particular to a transformer group.
