摘　　要： 针对谐振法测量电容电流在自动消弧线圈中测量误差偏大的问题,推导出连续无级可调消弧线圈谐振测量法的改进公式以及有级可调消弧线圈谐振法的一般公式。试验和现场运行表明,基于新的谐振法所研制的自动消弧线圈电容电流测量精度明显提高,具有推广应用的价值。 Aiming at the problem of bigger test error of automatic arc-quenching coil in capatitance current test by resonance method, the improved formula of resonance test method for continuous stepless adjustable arc-quencing coil and common formula for step adjustable arc-quenching coil were derived. Tests and field operation show the accuracy of capatitance current test of automatic arc-quenching coil is greatly improved and this method has a wide application range.
