Abstract
The current ultra-high voltage power transformer can not input or output power energy with two different voltage values for the same anti-freezing power cable. A technical proposal adopted for solving the defect is as follows: on the basis of a principal winding of each phase at the high-voltage side of the ultra-high voltage power transformer, an additional winding is added; the additional winding is electrically connected with the principal winding; the diameter of the additional winding is smaller than the diameter of the principal winding; when being put into operation, the line voltage of the additional winding is higher than the line voltage of the principal winding by 5V to 800V; and the additional winding is provided with a voltage regulating tap with the same performance with that of the principal winding, and a synchronous voltage regulating switch is arranged for synchronously regulating the voltage of the principal winding and the additional winding. The principal winding can input or output the power energy with the specified voltage for an operating sub-cable of the anti-freezing power cable, while the additional winding can input or output the power energy with required voltage for an auxiliary sub-cable of the anti-freezing power cable, thereby realizing the freezing resisting effect of the anti-freezing power cable.
