摘 要: 精确的测量和跟踪是自动调谐式消弧线圈精确地补偿系统电容电流、有效地熄灭接地点电弧的前提和基础。在模拟试验和现场运行经验的基础上,分析了影响测量精确度的几个问题,并提出了修正公式和应对措施;最后讨论了跟踪准确度和灵敏度的实现方法。 Precisely measuring and tracing is a precondition and basis of arc-suppression coil with automatic tuning accurately compensating system capacitive current and efficiently quenching ground arc. Based on the simulation test and practical experience, this paper analyzes several problems of affecting measurement in detail, and presents the correcting formulas and countermeasures. In the end, the accuracy and sensitivity of tracing are discussed.
