| 摘要 | PURPOSE:To reduce the capacitance of winding to be required as well as to simplify the whole constitution by a method wherein the whole range to be adjusted is divided into a fixed part and a variable part and phase difference is generated directly by a main winding and a phase winding in the fixed part, whereas the phase difference is generated indirectly in the variable part through a series transformer. CONSTITUTION:A terminal 1 of a main circuit of a transformer 18 of the main circuit is connected to three-phase electric power system and each phase is provided with a first and a second terminal parts 12 and 15 respectively. Between the terminal part 12 and a neutral point terminal 4, a middle point 13 is arranged. A main circuit terminal 2, which is connected to the system through a series winding 20 of a series transformer 21, is connected to the terminal part 12. A main winding 11 is arranged between the part 12 and a terminal 14 and a polyphase winding 14 is arranged between the middle point 13 and the terminal part 15. Then, the windings 11 and 14 between the terminal parts 12 and 15 are determined to be a variable part which has the constitution that the phase difference is generated indirectly through the transformer 21, whereas the main winding 11 and the series winding 20 are determined to be a fixed part of the adjustment range, which has the constitution that the phase difference is generated directly thereby reducing the capacitance of winding to be required. | ||||||
