    摘要： An electrical assembly includes a converter-based electrical device and a transformer for connecting the converter-based electrical device to an AC electrical network, a first transformer side of the transformer connected to the converter-based electrical device, a second transformer side of the transformer for connection to the AC electrical network, the transformer including a number of taps, the transformer including a tap changer operable to selectively connect to the or each tap to modify a turn ratio of the transformer. The transformer includes a controller configured to selectively operate the tap changer in an AC voltage modification mode, responsive to an abnormal operating state of the electrical assembly, to modify the turn ratio of the transformer so as to modify an AC voltage at the first transformer side.

    摘要： 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.
