12-Pulse Rectifier Circuit and Structural Type of Power Transformer

以6脉波整流电路为基础,着重研究12脉波整流电路与电源变压器结构型式,并对其产生谐波电流进行分析和计算,阐述了12脉波整流机组的连接方式,由此可以很好地抑制6脉波整流电路中某些特定次数的高次谐波。通过调整每台变压器网侧的匝数来改变电抗,对电流分配有调节作用,完全可使两台整流电路达到负荷电流平衡分配。

Based on 6-pulse rectifier circuit, this paper studied the 12-pulse rectifier circuit and tile structural type of power transformer, and tile harmonic currents were analyzed and calculated. Tile combining means of 12-pulse rectifier set were elaborated, and the certain higher harmonic were restrained well. The reactance was changed by adjustitlg the number of turns of per transfonner network side, which had the regulating effect on cmTent distribution, and the load currents of the two rectifier circuits were distributed averagely.
