分析了目前我国电力系统具有代表性的几种消弧装置，分别指出了它们的局限性。在此基础上提出了一种新颖的“阀式”结构可控消弧电抗器及其控制装置。理论分析和现场试验结果表明，新型可控自动消弧成套装置能够克服传统消弧装置的种种不足，并能对单相接地电容电流实现快速、精确的最佳补偿，具有重要的实用价值及应用前景。
This paper analyzes several typical arc suppression devices in China’s power system and points out their respective limitations. On this basis, a novel “valve type” structure controllable arc suppression reactor and its control device are proposed. Theoretical analysis and field test results show that the new type of controllable arc-extinguishing complete sets of devices can overcome the shortcomings of traditional arc-extinguishing devices, and can quickly and accurately compensate the single-phase capacitor currents with great practical value and application prospect.
