Abstract: A three-phase 48-pulse rectifier transformer includes two 24-pulse rectifier transformers phase-shifted through valve-side output windings. Each 24-pulse rectifier transformer has two sets of grid-side input windings and four sets of valve-side output windings. The two sets of grid-side input windings are connected in parallel and axially arranged in a split manner. Among the four sets of valve-side output windings, two sets of valve-side output windings are radially arranged in a split manner corresponding to one set of grid-side input windings, and the other two sets of valve-side output windings are also radially arranged in a split manner corresponding to the other set of grid-side input windings. The two sets of valve-side output windings that are radially split and the other two sets of valve-side output windings that are radially split are axially arranged in a split manner. The grid-side input windings of the two 24-pulse rectifier transformers are phase-shifted with respect to each other. In this way, a uniform difference of 7.5° is produced in voltages of the eight sets of valve-side output windings of the two 24-pulse rectifier transformers, and the eight sets of valve-side output windings of the two 24-pulse rectifier transformers are correspondingly connected to rectifiers to form a uniform 48-pulse rectifier transformer, which not only reduces the harmonic current generated by the rectifier, but also improves the load capacity of the rectifier.

Abstract: The present invention discloses a cell bottom structure of a reduction cell which comprises a reduction cell and a cathode bus, wherein the bottom of the reduction cell is provided with column-shaped cathode carbon blocks perpendicular to the bottom of the reduction cell, and a lower end of the column-shaped cathode carbon block is connected to the cathode bus. By means of inserting the column-shaped cathode carbon blocks perpendicular to the bottom of the reduction cell and connecting the lower end of the column-shaped cathode carbon block with the cathode bus, such that electrical current that guided from anode carbon blocks is guided through the molten aluminum to the column-shaped cathode carbon blocks and is downwardly guided out, the present invention reduces horizontal electrical current in the molten aluminum, such that the cathode extending into the molten aluminum can effectively reduce fluctuations of the molten aluminum to obtain a stable surface of the molten aluminum, thereby reducing a polar distance between a cathode and an anode and lowering cell voltage so as to achieve the object of lowering electricity consumption.
