Abstract

The invention relates to a low-voltage regulating transformer and belongs to the technical field of manufacture of transformers. According to the technical scheme, a voltage regulator is serially connected to a low-voltage winding of a power transformer and comprises two windings and a regulator core, one winding is a series winding (6) serially connected with a low-voltage winding (3) of the transformer, the other winding is an exciting winding (7) connected with a power supply winding (2), and the power supply winding (2) in the transformer is used to power the regulator. A tap regulating device of the regulator is connected with the exciting winding of the regulator, or connected with the power supply winding, which is inside the regulator and powers the regulator. Voltage of the series winding (6) in different tapping modes is optionally changed by adjusting the number of turns of the power supply winding (2), the exciting winding (7) and the series winding (6), so that voltage of the low-voltage winding is regulated accurately. The low-voltage regulating transformer has the advantage that the voltage of the low voltage winding of the low-voltage regulating transformer can be regulated accurately.
