摘　　要：针对上下移动电抗器线圈和改变气隙分布可使电抗器损耗变化20%以上这一现象,用ANSYS软件对干式铁心电抗器的磁场进行了分析,得出线圈涡流损耗与铁心电抗器结构的关系,并提出了设计电抗器铁心时应考虑安匝平衡,以降低铁心电抗器的损耗。通过电磁场计算,分析了铁饼高度与气隙长度对线圈涡流损耗的影响程度,得出合理的铁饼高度和气隙长度的范围,可为今后电抗器设计提供参考。Since moving up and down the reactor coils and changing the distribution ol the air gap can cnange reactor loss of more than 20%, the author used ANSYS software to analyze dry core reactor magnetic field, thus acquired the relationship between coil eddy current losses and core reactor structure, and proposed that balanced am- pere- turns should be considered in the design so as to reduce core reactor losses. Through the electromagnetic field calculation, it also analyzed the impact of the discus height and gap length on the coil eddy current loss so as to acquire the range of reasonable discus height and gap length, which provides the reference for reactor design.
