Abstract

A multi-phase transformer provided by the invention comprises a shell and an inductance transformation unit, the inductance transformation unit comprises a magnet assembly, a primary coil, a secondarycoil and an inductance coil; at least three placing spaces are formed in the shell, a blocking wall of the shell is blocked between two adjacent placing spaces, and an inductance transformation unitis arranged in each placing space; a first coil placement position and a second coil placement position are formed in the magnet assembly, the inductance coil is arranged in the first coil placement position, the primary coil and the secondary coil are arranged in the second coil placement position, and the inductance coil is connected with the primary coil in series. The shielding effect among the multi-phase inductance transformation units is ensured by the independent placement space; the primary coil and the secondary coil are concentrically arranged to reduce the volume of the magnet assembly, thereby reducing the volume of the multi-phase transformer; one-time resin encapsulation can be carried out in the shell, the heat dissipation performance of the product is guaranteed, the production efficiency is improved, only one-time positioning installation is needed when the multi-phase transformer is installed on a circuit, the installation difficulty is reduced, and the efficiency isimproved.

Description

technical field [0001] The invention relates to the technical field of transformer equipment, in particular to a multi-phase transformer. Background technique [0002] There is a single-phase co-packaged inductance transformer including a housing, a magnet assembly, a primary coil, a secondary coil and an inductance coil. The casing has a placement space, and the placement space is divided into an inductance space and a voltage transformation space by a barrier wall; the magnet assembly includes a first magnet, a second magnet, a third magnet and a fourth magnet, and the first magnet and the second magnet are relatively arranged on the inductance In the space, the third magnet and the fourth magnet are relatively arranged in the variable pressure space. The inductance coil is located between the first magnet and the second magnet; the first magnetic column and the second magnetic column are formed between the third magnet and the fourth magnet, the primary coil is wound on ...
