摘　　要：自励式可控饱和电抗器和传统饱和电抗器的区别在于,自励式可饱和电抗器不另设直流绕组,不需专门大容量的低压整流电源为其供电,以其绕组自身的抽头为整流晶闸管、二极管供电,利用晶闸管周期性导通,并改变触发角α产生可控的直流偏磁,对其阻抗进行调节。通过对某单位的10 kV自励式可控饱和电抗器性能的测试,确认该电抗器不仅具有传统电抗器启动方式安全可靠、免维护的特点,而且还具有可控硅串启动的优良"软"特性。Self-excited Controllable Saturated Reactor is differ- ence with conventional saturated reactor,it does not need an ad- ditional DC winding and a special big large-capacity low-voltage rectifying power supply, takes the own tap of its winding as the power supply of the rectifier thyristor and diode, and produce controllable DC bias by triggering the thyristor periodically and changing the trigger angle to adjust its impedance.The perform- ance test of a 10 kV self-excited controllable saturated reactor was carried out.It was be confirmed the self-excited controUable saturated reactor not only is safe and reliable in startup mode as well as maintenance- free as conventional reactor, but also has excellent characteristics of soft start as SCR series start.
