<p>PURPOSE:To obtain an arbitrary impedance by an autotransformer by concentrically winding part of a coil and part of a tertiary coil with a branch in series with the first core leng, parts of coils of series and shunt with the second core leg, tapped coil and further part of the tertiary coil on the second leg, and connecting the coils in series with or in parallel with each other in accordance with the prescribed system. CONSTITUTION:Part 4A of a tertiary coil, part 3A of shunting coil, and part 2A of a series coil are sequentially concentrically wound from the inside on one main leg 1A of two main legs of a single phase 4-leg core. Part 4B of the tertiary oil, tapped coil 6, part 2B of series coil and part 3B of shunting coil are similarly sequentially concentrically wound from the inside on the other main leg 1B. Thereafter, the coils 4A, 4B are connected in parallel with each other, tertiary terminals a, b are led, coils 3A, 3B are connected in series with each other, the coil 6 is connected in series at the neutral point sides of the coils, and middle voltage line terminal u and neutral point side terminal v are led. Further, the coils 2A, 2B are connected in series, and are led to the high voltage line side terminal U, and are connected to the terminal U side of the middle voltage side.</p> |
