摘要
Abstract
Using the mirror images method,empirical formula methods of CISPR and BPA,transmission line reference book 345 kV and above to analysis the influences of phase distance to ground,phase distance and parallel spacing on the ground electric field intensity,magnetic induction intensity,radio interference and audible noise under different rankings of phase conductors of 750 kV quadruple-circuit transmission lines,were found that the ground field and magnetic induction can be improved and independent of the parallel spacing under positive arrangement of phases.The RI and AN can be improved under alternating arrangement of phases.The most effective approach to improving RI and AN levels varies depending on the specific value of the phase spacing.关键词
