Abrégé
(EN)
A continuously variable saturable shunt reactor includes a laminated core having two wound limbs (1,2) for each phase connected by yokes. A network winding branch (3,4) is disposed on each limb, high-voltage ends of winding branches of a phase are connected to a phase conductor and low-voltage ends (N1,N2) of winding branches are connected to a DC voltage source, to reduce power of the DC voltage sources, degree of distortion of the operating current and control error, and to reduce the number of DC voltage sources. The DC voltage source includes two stabilized, single-pole-grounded power converters (6,7) with opposite polarities and two electronic transistor changeover switches (5a,5b) controlled by a control system (14), for each phase. The control system feeds direct current to the winding branches of a phase in pulses using the switches and the direct current is fed into the winding branches at opposite poles from different power converters.

一种无级可调饱和补偿电抗器,包括层压的芯,其每一相具有两个通过磁轭连接的被缠绕的腿部(1,2),在每个被缠绕的腿部上布置有网络绕组支路(3,4),且一个相的两个网络绕组支路的高压端连接到相导体,这些网络绕组支路的低压端(N1,N2)连接到直流电压源。该无级可调饱和补偿电抗器应该减小直流电压源的功率、工作电流的畸变度以及减小直流电压源的数目。为此,直流电压源包括两个极性相反的、稳定化且单极接地的换流器(6,7),且每一相包括两个由控制系统(14)控制的电子晶体管转换开关(5a,5b),且控制系统构建为使得一相的两个网络绕组支路的直流馈电经由相应的电子晶体管转换开关脉冲式进行,且从不同的换流器的相反极进行所述直流馈电。
