Abstract

The invention discloses an axial double-splitting rectification full foil winding transformer and a winding method. The transformer comprises one or more high-voltage windings (HV11, HV12 and HV21, HV22) and a low-voltage windings (LV1 and LV2). The two windings of the low-voltage winding set are different in phase and are connected with a rectification device. The winding directions of the HV11 and the HV12are opposite. The winding directions of the HV21 and the HV22 are opposite. The winding directions of the HV11 and the LV1 are same. The winding directions of the HV22 and the HV11 are same. The HV11 and the HV12 are connected in a series mode to form HV1. The HV21 and the HV22 are connected in a series mode to form HV2. The HV1 and the HV2 are connected in a parallel mode to form HV. The HV11, the HV12, the HV21, the HV22, the LV1 and the LV2 are all foil type windings. Needed insulating parts are few, the anti-short-circuit capacity is good, the production efficiency is high, the production cost is low, and the invention is suitable for the field of rectifier transformers.

Description

technical field [0001] The invention relates to the field of transformers, in particular to an axial double-split rectification full foil-wound transformer and a winding method. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. According to the different winding conductor structures, it can generally be divided into wire wound windings and foil windings. Foil winding uses copper or aluminum foil strips of different thicknesses as conductors, wide-band insulating materials as interlayer insulation, and narrow strip-shaped insulating materials as end insulation. The winding is completed once on the foil winding machine to form coils. shape coil. [0003] The State Intellectual Property Office of the People's Republic of China published a patent document titled "A Foil-Wound Transformer" on April 22, 2015 (Notice No.: CN204289063U). The disclosed foil-wound transformer includes: iron core; The m...
