摘　　要：介绍了ITER底部校正场线圈(BCC)管内电缆导体和氦管结构,对BCC管内电缆导体和氦管进行了压降实验。结果表明,低流量条件下气体的流动状态受到流道内摩擦的影响,由于摩擦系数无法通过经验公式进行计算,低流量条件下的摩擦系数被忽略。在较大流量条件下摩擦系数与雷诺数关系与标准样件实验获得的关系对应,完整的BCC校正场线圈的流阻符合理论设计值。The structure composition of cable conductor and helium tube for ITER bottom correction coils(BCCs) is presented, and its pressure drop experiment is carried out. The results show that the flow state of gas is affected by friction in flow channel at low flow rate. At large flow rate, the relationship between friction coefficient and Reynolds number corresponds to that obtained by the standard sample experiment, and the flow resistance of complete BCC tube accords with the theoretical design value.
