With the increase in the length of 110kV substation 10kV cable lines, resulting in the 10kV single-phase ground c-apacitive current significantly increased, and the automatic arc suppression coil compensation device has been widely used. I-n this article, the author describes several arc suppression coil automatic compensation device, and analysis of the selection criteria of the arc suppression coil. Compare with the advanta-ges and disadvantages of arc suppression coil, the author puts forward some selection recommendations of 110kV substatio-n arc suppression coil automatic compensation device.% 随着110 kV 变电站10 kV 电缆线路长度的增加，导致10 kV 系统单相接地电容电流明显增加，消弧线圈自动补偿装置得到了广泛的应用。本文介绍了常用的几种消弧线圈自动补偿装置，并分析消弧线圈的选择标准。通过对消弧线圈优缺点的比较，提出110 kV 变电站消弧线圈自动补偿装置的选型建议。
