本文介绍了0.2m Ω/d超导-正常态转换电感限流器的研究结果。讨论了BSCCO环。环中的热过程被发现有一个重要的影响的瞬态响应特性的限制器。与小型装置的显著不同之处在于，中型限流器中的淬火过程伴随着高温超导环的强烈加热。由于高损耗和大的热惯性，超导环在整个限制时间期间保持在正常状态，并且在故障发生之后在环中的超导状态恢复之前经过至少几个AC周期。<<ETX>>
The results of investigations of an inductive current limiting device prototype based on superconducting to normal state transition in 0.2 m o/d. BSCCO rings are discussed. Thermal processes in the ring were found to have an important influence on transient response characteristics of the limiter. In a marked difference to small scale devices, the quenching process in a medium scale current limiter is accompanied by an intense heating of the HTSC ring. Because of high losses and large thermal inertia, the superconducting ring remains in the normal state during entire limitation time and at least a few AC cycles pass before the superconducting state in the rings is resumed after a fault occurrence.<<ETX>>
