【摘要】 分析了目前我国电力系统具有代表性的几种消孤装置，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”结构可控消抓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抓装置的种种不足，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。更多还原

【Abstract】 Based on the comparison of advantages and disadvantages of several representative arc extinguishing apparatus. a new type magnetic valve arc extinguishing apparatus is introduced in this paper. The results of theoreticaI analysis and field testing show that the new type arc extinguishing apparatus can overcome the shortcomings of traditional ones and can provide a quick. accurate and optimal compensation to capacitive current in single-phase earth fault. It has important practical value and application prospect.更多还原
