介绍SWIP-RFP装置等离子体环电压和环电流的测量方法和测量结果。对RFP环电压模型也作了初步分析,实验中采用单匝线圈测量的环电压很大程度地取决于外电路的电流,这一电压中存在一感应分量,即使考虑了测量环电压的感应分量,RFP等离子体的环电压也要大于环形磁约束系统等离子体的经典电阻环电压,这是反场箍缩等离子体螺旋量 Describes the methods and measurements of the plasma ring voltage and ring current of SWIP-RFP devices. A preliminary analysis of the RFP ring voltage model was also carried out. In the experiment, the loop voltage measured by a single-turn coil largely depends on the current of the external circuit. There is an inductive component in this voltage even though the inductive component , The RFP plasma ring voltage should also be greater than the ring magnetostatic system plasma classic resistance ring voltage, which is the reverse field pinch plasma helix
