摘　　要：提出了一种不产生谐波,宽范围自动快速补偿对地电容电流的新型自动调谐消弧线圈的设计原理,其核心是基于磁通可控的大容量连续可调电抗器,而系统对地电容检测采用频率扫描法。文中详细分析了它们的原理,并说明了系统实现接地故障时电抗器与对地电容自动调谐的方法。样机实验证实了设计原理和方法的正确性。In the paper, a new principle of automatic resonantarc-suppressing coil is proposed, which produces no harmonics and automatically compensates the grounding capacity current with rapid response in a wide range. Its main part is a continuously adjustable high power reactor based on controllable magnetic flux. The method of frequency scan is used to detect grounding capacity. Their principles are analyzed in detail, and the way to realize automatic resonant of the adjustable reactor and grounding capacity is explained when the single -phase earth fault occurs. The principles and methods are proved by experiment results of a prototype.
