摘要(Abstract)：

基于钳形Rogowski线圈的互感器能够有效避免现场安装过程中的线路停电现象,减少停电损失。但是钳形Rogowski线圈测量过程主要受到气隙和一次导体偏心的影响,为研究钳形Rogowski线圈的性能,建立了气隙-偏心误差模型,充分分析气隙和一次导体偏心对线圈测量误差的影响,在此基础上提出了相应的误差补偿方法,并设计了一种基于校正PCB板的新型钳形Rogowski线圈,通过监测校正PCB板串联输出量,实现线圈的气隙自校准,从而实现测量误差的补偿。应用效果表明,设计的钳形Rogowski线圈测量准确度高,操作方便。

关键词(KeyWords)： 钳形Rogowski线圈;气隙;一次导体偏心;PCB板;误差补偿
