[0013] Example
[0014] like figure 2 As shown, it is a schematic diagram of the voltage regulation wiring of the three-phase on-load voltage regulating autotransformer provided by the present invention. By changing the iron core magnetic flux of the transformer, the voltage regulation of the high voltage voltage is realized, and the series windings 1 in the transformer are connected in series in order Winding 2, voltage regulating winding 3, that is, the voltage regulating winding 3 is connected in series at the end of the common winding 2, and the three-phase on-load voltage regulating autotransformer adopts a three-phase integrated voltage regulating switch. The voltage regulating winding 2 is located at the end of the common winding 3, and the current outflow terminals of the voltage regulating winding 2 (ie, the current outflow terminals of the voltage regulating switch) are connected together. Because the current outflow terminal of the three-phase integrated on-load s...
