介绍了EAST快速控制线圈的设计参数、电磁水冷分析和安装过程。引线部分受到巨大的垂直于自身方向的震荡力，常规的有机绝缘材料不能满足要求。线圈的绝缘材料采用 MgO 粉末，并在引线两端增加支撑固定。水冷计算表明，铜导体和水的稳定温度与点到进水口的距离成线性关系；当线圈通电电流为20kA时，为了保证出水口的水温不被加热至100℃，水的最小流速与运行效率的关系为v≈6K。

The design parameter, electromagnetic and water-cooling analysis and fabrication process of EAST active feedback control coils are presented. As the diagonal leaders suffer huge vertical force variation, conventional organic insulating material cannot meet the requirements. Magnesium oxide was used as insulating material and supports were added to both ends of the diagonal leaders. Water-cooling calculations show that the temperature of the copper conductor and water is linearly related to the distance from the point to the water inlet. In order to assure the temperature of outlet water not be heated to boil, the relation of the minimum velocity of water and operation ratio is about v≈6K when the current in the coil is 20kA.
