应用 Applications
整流电抗器是用来减少线电流里的谐波成分，限制短路电流，使线电压波峰波谷值衰减，从而延长了电力半导体设备的使用寿命，限制了开关瞬间的转换电流。整流电抗器的串连阻抗由50Hz下相对电压降du％表示。它是由在额定电流下，与额定线电压的百分比值计算得出。
The function of these reactors is to reduce harmonic in the line current， to limit the short circuit currents (thanks to reduction of di/dt rate)， to attenuate the line voltage peaks and sags and to extend the power semiconductor devices operating life， by limiting the transition currents during switching instants. The series impedance provided by communication reactors is expressed by the relative drop dU% at 50Hz， calculated as a percentage of the rated line voltage， at nominal current.
