LOW-VOLTAGE LEAD STRUCTURE OF SINGLE-PHASE MULTI-WINDING TRANSFORMER

WIPO Patent Application WO/2022/226916

A1

The present invention relates to the technical field of transformers, and provides a low-voltage lead structure of a single-phase multi-winding transformer, comprising a fuel tank, a plurality of single-phase transformers being provided within the fuel tank, a plurality of plug-and-pull type sleeves also being provided on a side wall of the fuel tank, and the plug-and-pull type sleeves being connected to coil connection points of the single-phase transformers by means of connection leads; and the low-voltage lead structure further comprises: a wire support, which is disposed within the fuel tank, the wire support comprising a plurality of mounting rods disposed in a first direction and a plurality of mounting rods disposed in a second direction, and the mounting rods each being provided with a plurality of wire clips. The foregoing technical solution solves the problem in the existing technology in which arranging a plurality of leads of a low-voltage side output of an in-phase power supply transformer is difficult.
