CURRENT-LIMITING REACTOR Russian patent published in 2001 - IPC

FIELD: electrical engineering; transformer manufacture; power reactors. SUBSTANCE: reactor has winding whose turns incorporate n parallel conductors, where n is integer number equal to or greater than 3, and m rows, where m is integer number equal to or greater than 3, arranged axially perpendicular to winding axis; parallel conductors are transposed at junction points between conductors of each preceding row and those of next one; common transposition of all parallel conductors is made at junction points between conductors of each odd-numbered row and those of next even- numbered one. Novelty is that at junction points between conductors of even-numbered row and those of next odd-numbered one transposition is made so that n-th conductor of even-numbered row is radially placed in same position in next row, (n ≥ 1)-st conductor of even-numbered row is placed in position of first conductor in next odd-numbered row, (n ≥ 2)- nd conductor of even-numbered row is placed in position of second conductor in next odd-numbered row, etc. ; accordingly, second conductor of even-numbered row is placed in position of (n ≥ 2)-nd conductor of next odd-numbered row, first conductor of even-numbered row is placed in position of (n ≥ 1)-st conductor of next row. EFFECT: improved uniformity of current distribution, facilitated manufacture, reduced consumption of active and insulating materials. 1 dwg
