    Abstract: A single-phase electric furnace transformer is provided according to the basic principle of the invention, comprising: a single magnetic core, said magnetic core comprising two side columns and at least one main column; a main transformer, comprising a first primary side winding and a first secondary side winding which are disposed on said at least one main column, wherein said first primary side winding consists of a first winding and a second winding which are connected in series with each other; and a voltage regulating autotransformer, which is disposed on one of two side columns of said magnetic core, and which comprises a second primary side winding and a second secondary side winding, wherein said second secondary side winding is an adjustable winding having on-load tap switch, and said adjustable winding is connected in series between the first winding and the second winding of said main transformer. The direct effect on the regulating winding and the regulating switch by the over-voltage of the grid can be avoided in the single-phase electric furnace transformer of the invention, and the voltage between two terminals of the primary winding of the main transformer can be reduced. Furthermore, the winding of the voltage regulating transformer is disposed on the side column of the main transformer in the invention, so that the material and the transformer loss can be reduced, and the installation space of the transformer can be decreased.
