三相电抗器;THREE-PHASE REACTOR

摘要

本案公开了一种三相电抗器，包括：一上轭部和一下轭部，上轭部和下轭部包含第一材料；至少三个第一芯柱，第一芯柱包含第二材料，且第一芯柱的两端分别与上轭部和下轭部连接；第一材料的相对磁导率高于第二材料的相对磁导率，并且每个第一芯柱设有至少一个气隙。本发明提出的三相电抗器采用不同的材料制成轭部与芯柱并且在芯柱中开气隙，能够极大地降低涡流损耗，满足大功率的使用要求。;The disclosure relates to a three-phase reactor. The three-phase reactor includes an upper yoke, a lower yoke and at least three first core posts. The upper yoke and the lower yoke include first materials. The first core posts include second materials, and two ends of each first core posts are respectively connected with the upper yoke and the lower yoke. The relative permeability of the first material is higher than the relative permeability of the second material. In addition, each of the first core posts has at least a gap. The three-phase reactor of the disclosure utilizes different materials for forming a yoke portion and core posts having gaps, so that the eddy current loss is effectively reduced, and the demands of large power are met.
