摘　　要：对托卡马克装置内壁产生巨大电磁力是等离子体破裂重要和直接的影响,这会对装置的安全运行造成巨大威胁.等离子体破裂期间电流猝灭率不仅与真空室内第一壁的负载设计有关,并且与装置重大部件的设计也相关.本文选用100%-40%区间统计研究等离子体破裂现象.分析结果表明:100%-40%区间统计下HL-2A上最小电流猝灭时间为0.7 ms,对应的最小面积归一化电流猝灭时间为1.4 ms m^(-2).瞬时最大电流猝灭率与平均电流猝灭率的比值大部分都大于1.An important and direct effect on the plasma breakdown is the huge electromagnetic force on the inner wall of Tokamak device, this will constitutes a serious threat to the safety of tokamak devices. The current quench rate is related not only to the design load of smaller in-vessel components, but also to the design of large components. The data of current quench have been statistically analyzed by using 100%-40% of the pre-disruption. The experimental results show that the minimum current quench time is 0.7 ms, corresponding to minimum area normalized current quenching time 1.4 ms m^(-2). The value of maximum instantaneous IP quench rate versus QR(100-40) are greater than 1.
